Quick Tips #210

Mold is everywhere around usoutside in soil, wood and rotting plants, and inside on carpet, drywall, wallpaper and insulation. Outside molds carry out natures work by breaking down decaying organic material such as dead plants, fallen trees or dead animals. Inside, mold growth can cause an array of health concerns. However not all mold is harmful; without mold we would not have certain food and medicines like cheese or penicillin. Mold is one category of non-green, plant-like organisms (along with mildew, mushrooms, rusts, smuts and yeast) that fall within the fungus family. All fungal matter shares the common characteristic of being capable of growth without sunlight. Because of this, mold can be found almost anywhere, and can grow on almost anything as long as moisture and oxygen are present. Many types of mold exist with approximately 1,000 known species found in the United States, and over 100,000 species worldwide.

Currently, there are no federal standards or American Conference of Governmental Industrial Hygienists (ACGIH) established threshold limit values (TLVs) for airborne concentrations of mold or mold spores. According to the Environmental Protection Agency's (EPA's) Mold Remediation in Schools and Commercial Buildings resource, allergic reactions to mold are common. Mold can produce allergens that can trigger allergic reactions, asthma attacks or produce potent toxins and/or irritants. Hypersensitivity pneumonitis (lung inflammation) has also been linked to mold exposure. People with the greatest risk of health effects from mold exposures are the elderly, the very young and expectant mothers, as well as individuals with mold allergies, asthma and other chronic respiratory ailments.

Mold growth frequently occurs when excessive moisture or water accumulates indoors. There is no feasible way to eliminate all molds and mold spores indoors, so the most effective way to control indoor mold growth is to control moisture. In buildings where mold is a problem, the mold must be remediated and the sources of moisture identified and eliminated.

It is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth from starting. Water-damaged porous or absorbent materials, such as ceiling tiles, wallboard, cellulose and fiberglass insulation, should be discarded and replaced. Discard non-valuable books and papers. Be sure to photocopy important paperwork before discarding the originals. Use a water extraction vacuum to remove water from carpeting. Then use dehumidifiers and fans to accelerate the drying process. Carpet that becomes moldy usually must be replaced. Nonporous surfaces can be vacuumed or wiped with mild detergent and allowed to dry completely.

Identify and repair leaky plumbing, roofs and other sources of water in a timely fashion to prevent moisture and mold growth. The EPA suggests you can minimize mold growth by reducing indoor humidity to below 60% and ideally between 30 and 50%. This can be done by venting bathrooms, kitchens, dryers and other moisture-generating sources to the outside; using air conditioners and dehumidifiers; increasing ventilation; and using exhaust fans whenever cooking, dishwashing and cleaning.

Also, reduce the potential for condensation on cold surfaces like windows, piping, exterior walls, roofing and floors by adding insulation. Do not install carpeting in areas where there is a continuous moisture problem, such as near drinking fountains, sinks or on concrete floors with leaks or frequent condensation.

A visual inspection is the most important initial step in identifying a possible contamination problem. The extent of any water damage and mold growth should be visually assessed. This assessment is important in determining mold remediation strategies.

Ventilation systems should also be visually checked, particularly for damp filters, but also for damp conditions elsewhere in the system and overall cleanliness. Ceiling tiles, gypsum wallboard, cardboard, paper and other porous surfaces should be given careful attention during a visual inspection.

The use of special equipment to view spaces in ductwork or behind walls, and/or by using a moisture meter to detect moisture in building materials, may be helpful in identifying hidden sources of mold growth and the extent of water damage.

The EPA's remediation guide for schools and commercial buildings offers detailed recommendations for a variety of mold removal scenarios and is a tremendous resource for anyone facing a mold problem.

Mold should be cleaned as soon as it appears. OSHA considers small remediation areas, less than 30 square feet (sq. ft.), of mold, which can be cleaned using a detergent/soapy solution or an appropriate household cleaner and allowed to dry completely. For larger areas (30-100 sq. ft.), there are commercial products that can be used for cleaning, disinfecting and sanitizing. Mold-resistant coatings are also available for use on insulation materials and inside duct work. A HEPA vacuum can be used to clean items such as furniture, concrete, carpeting or books after the material has been thoroughly dried.

According to OSHA, for small areas of mold growth, an N95 respirator, non-vented goggles and long gloves compatible with the chemicals used for surface cleaning should be worn. For larger mold remediation jobs, or in situations where high levels of airborne dust or mold spores are likely or long-term exposures are expected, the EPA suggests a full-face, powered air purifying respirator (PAPR) along with disposable coveralls, gloves and shoe covers. The cleaned area should be thoroughly dried. Dispose of any sponges or rags that were used to clean the mold, along with the used personal protective equipment (PPE).

If the mold returns quickly or spreads, it may indicate an underlying problem, such as a leak or excessive humidity. Any underlying water problems must be fixed to successfully eliminate mold problems from reoccurring. If mold contamination is extensive, an experienced remediation professional may need to be consulted.

A mold remediation project is something that might be small enough to handle on your own or requires professional intervention. Costs range from the price of some cleaning products and some elbow grease to thousands in professional restoration services like shown above. This large price discrepancy is why hiring an independent mold inspector separate from the removal process is a wise decision. Having an unbiased third party assess your proper is the best way to determine exactly what your home or business requires in terms of cleaning.First, we will discuss situations that professional mold removal services are NOT necessary. These instances can be seen when common non-toxic mold like cladosporium or basidiospores are seen throughout a property. Examples of this type of mold growth can be seen in showers, tubs, sinks, around window ledges, and on air conditioning vents. Fungus like this grows because of condensation that happens at a place where environments naturally change from hot to cold. Anyone can handle a cleanup like this because it is happening on a non-porous (Hard) surface like tile, aluminum, or metal and the species present is non-toxic. A bleach based cleaner can be used to clean up this type of growth, but we always recommend a more specific mold cleaning solution.On the other hand when a home or business has had some type of water damage you may require professional restoration services. Things like a pipe burst/leak, roof/window leak, flooding can all cause these types of issues. Organic building materials like wood, drywall, and insulation are perfect nutrients for mold to feed on. Add water to the equation and you have the recipe for some serious problems. Even if you do have these types of issues, it is possible that they can be cleaned and dried before any fungus starts to grow. Having air and surface samples collected by an independent mold inspector is the best way to determine if any problems have indeed started from the water damage. In the event mold colonies have in fact started to sprout on the building material inside your home or business, here is a typical procedure for what needs to be done in order to get rid of the problems.

Mold Remediation - Mold Inspection & Testing

The mold remediation industry is inundated with techniques totreatattic mold. Wire brushing, HEPA vacuuming, dry ice blasting, coatings with mold killing swords (seriously this exists), the list is quite long. One would assume this plethora of options would allow the best solutions to rise to the top and eventually the dubious techniques would fall away. This assumption would be very wrong.

The problem is revealed even before we talk about the types of treatments available. Its in the name itself. By referring to the task of mold remediation as a treatment it implies that the solution lies in some sort of chemical or coating. Treatments make sense in many situations. If youre building a deck, pressure treated wood will greatly increase the life of your lumber. If you have an insect problem, spraying a bug treatment around your property is a sensible technique for keeping the pests away.

You would not, however, treat a leaky pipe or a flooded basement. You would fix/ repair/ remediate/ the water intrusion problem. Yet when you step into the unscrupulous mold remediation industry, something strange occurs. Many contractors are perfectly happy to sell a treatment without fixing the underlying problem. All too often this succeeds. Why? Most homeowners have never dealt with a mold issue and have a difficult time parsing out the scam from the solution.

The motivation to forego fixing the underlying problem is understandable. Fixing the cause of attic mold growth can be hard. Crawling around the entire attic counting can lights and collecting measurementsis fairly unpleasant. Popping your head up in the attic for 2 minutes and performing your inspection from the hatch is a tempting alternative.

But of course, this is worthless. This is akin to hiring a plumber who, after finding a leaky drain pipe, doesnt bother fixing the broken pipe and instead tries to sell you a dehumidifier. If this sounds absurd, youre right. Yet, this is how 90% of attic mold projects are handled.

The attic in the image above was treated only 4 months before this photo was taken. Youll notice the mold growth is unimpeded by the mold treatment. Why is this? Unfortunately, all treatments run about against a cold, wet, unyielding fact: Within a few months a layer of dust settles on the treated surfaces (even inverted surfaces). This dust contains a lot of organic material. Mold eats organic materials. So, while the coating is proudly protecting the the sheathing beneath it, the mold is happily growing on the dust. Now, this is not entirely true. In time, the coating will fail and the mold will extend its growth into the sheathing.

This is a big giveaway. If the service a contractor isoffering doesnt actually solve the problem, the verbiage in the warranty will reveal the lack of confidence. Youll find it lurking amidst the legal jargon as an exclusion against any recurrence of moisture issues. Which, of course, is the whole reason you would seek a warranty in the first place. Mold growth onlyoccurs when elevated moisture is present. It will not grow in a dry attic. Therefore, if a warranty becomes void in thepresence of elevated moisture, the treatment hasnt accomplished anything.

Now the hard part begins. Its easy enough to shoot holes in the treatment only techniques. Its quite another task to successfully identify the cause of attic mold growth in each unique situation. The cause of the excess moisture must be clearly identified. In most cases, this is due to several compounding factors.

Poorly connected exhaust fan

Condensation often masquerades as a roof leak. The image below is showing the conjunction of the skylight and the roof. This is a common place for roof leaks. Its also a common location for condensation problems. During showering, a bathroom is inundated with tremendous amounts of humidity. If the exhaust fan isnt working well or the skylights are set in a deep channel in the ceiling, the warm moist air will become trapped in this area. Unless its well sealed, the moisture will quickly move into the attic space where it will hit the cool surface of the roof sheathing.

Attic mold remediation should include techniques to limit the amount of air movement from the occupied portion of the house into the attic. Much of the condensation that leads to mold growth in an attic is due to moist air move up through the ceiling. The discoloration on the insulation in the photo below shows this air movement.

Mold caused by lack of air sealing

Can lights can be a major source of air infiltration in the attic. This is especially true with older can lights without an AT rating. Notice the discoloration of the insulation around the can light. This is due to the leakage of warm, moist air through the gaps within and around the can light assembly.

If the mold remediation occurs during the winter months, dry out of the attic sheathing is often necessary. This can be accomplished either through the natural moisture loss that will occur due to the increased ventilation, or through active dry out with heaters, dehumidifiers, etc. We prefer to let an attic dry out naturally, as this provides strong evidence of the effectiveness of the ventilation improvements.

During extremely cold weather, the moisture on the sheathing may even freeze, leading to a white, frosty coating. If the condensation is heavy, dripping from the sheathing will begin to occur. This can look very similar to a roof leak and often leads to a misdiagnosis.

Water droplets on attic / roof sheathing due to condensation

Severe condensation leading to dripping on rafters

After the first two steps are addressed, themold growth itself is addressed (although sometimes this step is addressed before/during the dry out period).

*Heads up I earn a small commission on sales through Amazon links. This helps cover the expense of running the website (and answering your questions!)

Happy to help. In the photo it appears the soffit vents (assuming you have soffit vents) are blocked by the insulation. If so, its important to pull these back to allow the movement air up through the soffits. I always recommend rechecking the attic again during the fall/winter months as the condensation issues are most prevalent during cold weather.

Homeowners insurance covers mold damage if it was caused by a "covered peril." Otherwise, an insurance company will likely not cover mold damage. There are exceptions, which we will get into later in this article.

Home insurance policies usually don't cover mold that resulted from a preventable water leak, flooding, or high humidity.

Home insurance companies also typically don't pay for maintenance issues that insurers think a homeowner should have prevented. Insurers expect homeowners to proactively take care of those problems before they need to file an insurance claim.

Home insurance covers mold if a "covered peril" caused the mold. In that case, your home insurance policy will likely pay for repairs and clean-up.

Here are some of home insurance's covered perils:

Let's take a look at some real world examples. When home insurance will likely cover you:

These are "sudden and accidental" incidents. Insurance companies typically cover this type of damage. In fact, non-weather-related water damage is one of the most common home insurance claims and one of the most expensive.

There are many instances when your home coverage won't protect you. Here are some examples.

Your basement pipes freeze and burst. You don't notice it for a few weeks. Now, you have a few inches of water on your floor and mold growing.

Broken shingles on your 40-year-old roof allows water into the attic. Water saturates wood and insulation and leads to mold in the attic.

Mold forms in your shower. You don't think much about it until one day you notice that it's really unsightly and you're concerned about whether it's making your family sick.

In these cases, an insurer will likely not cover the damage. Why? An insurance company expects you to take care of your house. That means properly ventilating the bathroom, replacing an old roof, and checking your basement regularly. An important reason to stay on top of home maintenance.

Also, the standard homeowners insurance policy doesn't cover water damage caused by a flood. Thus if a flood causes water damage that leads to mold, the resulting mold issue wouldn't be covered by your home policy.

A separate flood policy will cover mold and mildew, as long as its not caused by the homeowners failure to inspect and maintain the property after the flood. That means, once you can get back into your home, you need to start trying to clean up and keep mold from growing or spreading.

Home insurance companies usually don't cover mold damage unless it's directly related to a "covered peril." The good news -- there are exceptions.

Check your homeowners insurance policy to see if there is any language about mold claims. Some insurers offer limited coverage for mold claims. This may mean limiting how much the insurer will pay for a mold-related claim. Or an insurer may increase the cost of a home insurance policy if you have mold-related coverage.

If you don't have mold coverage, you can buy an endorsement to your insurance policy that adds mold coverage. An endorsement is when an insurance company adds additional coverage to a regular home insurance policy, for an additional fee.

Some home policies provide a limited amount of coverage for mold claims. This can be by capping the amount the insurer will pay, for example at $5,000, or stating that the insurer will only pay for certain services, such as clean-up, and excluding others, such as testing and remediation.

Insurance companies hate risk. In fact, the insurance industry is all about limiting risk.

Risky homes, such as old homes with old wiring and plumbing, and risky areas, such as high-crime neighborhoods or homes near woods that often catch fire, usually have more claims. Insurance companies don't like paying out many claims.

The same goes for a home with mold or ones with previous mold-related claims. Insurance companies view those homes as risky.

In that case, your insurance company will likely decline a mold endorsement or charge you a lot for that coverage.

That means it might be worth paying for the mold removal yourself.

Similar to any other home insurance claim, contact your insurance company as soon as possible to file a mold claim.

If you're not sure if your policy covers mold damage, check your home insurance policy or call your insurance company.

Mold grows quickly so take photos and then stop the source of the leak and clean up the water before calling your insurance company. An insurance company expects you to be proactive in fixing problems and avoiding further damage.

Here are the steps to take:

Don't throw the materials away until you call your insurance company. Take photos and keep the damaged materials. An insurance adjuster might want to see the damaged materials. Put them in a garage or another place that's away from your living areas until you meet with an insurance adjuster.

If you're concerned about possible health risks, discuss with your insurance company if there's a need to move out of the house. If you do need to move out until the mold is removed, determine how much additional living expenses (ALE) your home insurance will provide you.

Mold forms and spreads quickly so it's important to prevent mold by reducing moisture.

The Centers for Disease for Disease Control and Prevention suggests the following ways to control mold growth:

Mold needs moisture and a "food source" to grow. Food sources include insulation, drywall, carpeting, and mattresses.

Mold is most commonly found in places with high humidity. That can include under leaky pipes and appliance hoses, in attics under a leaking roof, and in basements with drainage issues.

If you want mold insurance and it's excluded from your homeowners insurance policy, ask your home insurance company if you can add an endorsement to your policy. An insurer bases the cost on your home and area's risks.

Mold endorsements will cost you more in humid areas and in older homes made with materials more prone to mold. The cost can range between $500 and $1,500 annually.

Mold Removal Cost

The average cost of mold remediation is $2,325, with most homeowners spending between $1,500$3,150 or $15 to $31 per square foot. A small mold removal job costs an average price of $500$1,500 while a larger job costs around $3,000$6,000. If the moldy area is 10 square feet or less, you can handle the job yourself for about $50.

In some cases, mold remediation costs can escalate to tens of thousands of dollars if the mold has spread and the problem is severe. Mold mitigation costs vary depending on how much and where mold exists. Broken down, mold removal professionals charge $75$108 per hour.

Factors affecting the cost of mold abatement include how early the mold is detected and treated. If untreated for too long, additional costs mount because repairs of damaged drywall, lumber, subflooring, siding, and other potential areas might be warranted. The damage that needs to be addressed alongside the mold can increase costs by $5,000 and beyond.

Professional mold removal costs between $15 and $31 per square foot. The average cost for mold mitigation in a 100 square foot room will run $1,500$3,150. When mold growth becomes an issue in your home, you will need to consider three main categories of related expenses when looking at the final cost:

Overall, the final mold cleaning cost will depend on where the mold is in the home and how extensive the damage is. Most companies prefer to charge per hour, in line with prevailing rates in their area. The average cost to hire a mold abatement professional is $75$120/hour.

Mold usually grows in your attic because of a moisture problem from a leaky roof, leaking AC unit, or condensation from poor attic insulation. Attic mold treatment costs $1,500 to $3,500 on average and can go as high as $6,000 to $10,000 if the leak is large or has gone undetected for a long time.

Mold most frequently grows in basements because of the indoor high humidity, flooding from leaking pipes, and underground dampness. Mold also tends to grow in basement drywall, wood, and insulation. Treatment by a licensed professional includes vapor barriers on basement walls and floors to keep the high humidity from seeping through. Basement mold removal costs between $500 and $2,500 depending on the extent of the damage.

Return to Top

Bathrooms are usually not well ventilated, and moisture and mold can collect in the shower and bathtub, sink, and drains. Typically, bathroom mold removal costs $500 to $1,500.

The average cost to remediate mold growth in a crawl space is around $500 to $1,500 depending on how big the crawlspace is and how much mold is present. The average crawl space will take five to eight days to remediate from start to finish. The process involves the following:7

Pump dry heat into the crawl space to attract moisture so it can be vented out of the small area. Remove the mold. Use a High-Efficiency Particulate Air (HEPA) vacuum on the entire crawl space, remove all debris. Seal wood framing to prevent mold growth. Install vapor barriers to seal out ground moisture and wrap pilon supports.

Return to Top

Removing mold growth on drywall or concrete walls will cost between $15 and $31 per square foot. In many cases, the drywall or concrete may need to be replaced. In that case, the cost of drywall installation is around $2.12+ per square foot.

Throw out any clothing with mold on it. Mold can sometimes be removed from curtains if you ask a dry-cleaning establishment to try. Drop off curtains in a sealed bag to prevent any contamination of other clothing there. Expect to pay an additional $1 or 10% more than regular dry-cleaning fees for the service with the knowledge that they might not be able to take out some mold stains.

Return to Top

Mold grows from moisture in the air ducts from hot and cold air condensing in the vents. Because mold spores become airborne, youll need to turn off your HVAC system once mold is discovered, so you dont spread it through the home. The average cost for HVAC mold treatment is between $2,000 and $8,000 because ventilation systems require special cleaning.

You may need to replace all the hard surface air ducts and any infected insulation. Replacing air ducts and vents cost $110 to remove, $12$20 per foot to install on the second floor, and $24$38 per foot to install in walls. Add an additional $1.90/sqft of surface for insulation.

Heating, ventilation, and air conditioning systems require special cleaning, which can potentially increase costs. Be aware that no chemical biocides are currently registered by EPA for use in internally-insulated air duct systems, should your contractor recommend using them in the proposal.

There is also a possibility you will also need to replace your furnace:

If the entire house flooded and mold is everywhere, it could cost $15,000 to $30,000 or more to remove the mold and repair all the water damage. If you want to ensure mold is prevented in future, you might need to replace your windows for $300+, improve the drainage system in your basement for $200$1,000, to prevent any standing water, and regrade the land around the foundation for $300$1,000.

Black mold is the most dangerous type of growth that leads to serious health risks. A regular black mold testing kit will find black mold just as quickly as the other varieties of mold. A black mold test will cost you about $195 for a visual inspection, $350 for visual and indoor/outdoor sampling, and $8$45 for a home mold testing kit.

Youll need to hire a licensed mold remediation company to remove all your black mold because cleanup includes full containment of the affected area, protective gear for the remediation team, and safe disposal methods. Containment alone is $0.33/cubic foot.

A licensed mold assessment consultant prepares a protocol. The report will list recommendations for the remediation method, the materials to be remediated, the personal protective equipment, containment required, and the criteria for clearance. A small mold remediation job costs an average price of $1,500 while larger areas cost about $3,000$6,000. Keep in mind that these prices do not include repair work.

Here's the average mold treatment cost breakdown for a 10 x 10 (100 square feet) bedroom with mold on one wall:

Return to Top

On average a visual mold inspection costs around $195, while a visual and sampling testing costs $350. Many mold removal professionals offer free testing which includes an examination of past and current signs within walls, floors, and ceilings, sources of moisture, and indoor air quality.

Not every mold issue requires sampling and testing. If you can already see the mold, theres no need for testing in that areaa test will merely confirm the presence of that mold. However, a thorough inspection will find all the areas where mold is growing in your house.

Detecting and testing for mold with a DIY home mold test kit costs $8 to $45.

Mold can grow in your home in three common types:[1]

While black mold is more toxic and worse for health issues, all mold is dangerous for your health and needs to be removed.

Mold is a fungus that grows in threads of many types and colors. It causes natural materials to biodegrade, cause certain diseases through allergic sensitivity and can grow pathogenically in the body. Some types of mold can even infect and grow in the lungs or cause hearing loss, and some are carcinogenic. When its found in a home, it should be remediated, as it grows and spreads very quickly via airborne sporessometimes starting a colony within two days. One spot of mold can grow out by 30 feet.

While mold cant be eradicated, it can be contained and prevented from spreading. You can stop future mold growth by installing proper ventilation and controlling the humidity levels in every room of your home and fixing any pipe, roof, or window leaks immediately. If any flooding has occurred, clean and dry the area thoroughly.[3]

Mildew and mold are both fungi, and because they grow and spread by sending their spores through the air, they can both affect the health of everyone in the home. Mildew is easier to remove with some hard scrubbing and the right cleaner, whereas mold invades carpets, floor, and walls and might need to be contained as its cleaned and removed.

Mold testing will cost about $195 for a visual inspection, $350 for visual and indoor/outdoor sampling, and a home mold testing kit costs $8$45. Some mold professionals offer free testing.

On average, professional mold remediation costs $500 to $6,000 with most homeowners spending between $1,500$3,150 or $15 to $31 per square foot. However, the price can escalate to tens of thousands if the mold problem is severe and left untreated for a long time.

On average, mold remediation costs $15 to $30 per square foot depending on how much and where mold exists. Broken down, a mold remediation specialist charges $1,500$3,000 per 100 sq. ft. or $75$108 per hour.

The way to ensure the removal of all the mold is to hire a licensed mold removal company to do it for you. The affected area must usually be contained with polythene sheeting, the area cleaned, the mold removed, and all containment materials disposed of. Removal will be done in one of three ways: Antimicrobial cleaningmold is sprayed or cleaned with a sponge; abradingmold spores are removed by sanding, brushing, or scraping; or dry ice blastingmold is cleared with dry ice plus removal with a HEPA filter vacuum (removes 99% of mold spores very quickly). Materials cleaned are then encapsulatedmold residue is sealed to hinder future growth. Any affected portions of drywall, flooring, etc. are also replaced.

Some people compare the smell of mold to the smell of wet socks, or rotten wood or paper. If you smell it, youll need to remove it rather than try to mask the smell, because mold can multiply quickly and destroy everything it grows on, and also make people in the homesick. The Center for Disease Control and Prevention says you need to clean up the mold and fix the moisture problem to prevent its recurrence. See their recommendations here.

Most homeowners insurance policies do not provide coverage for mold. If a pipe bursts and you call a plumber immediately, an insurance company will likely cover your claim. However, if there was a small leak and you decided to put it off for a while which led to the growth of the mold, the insurance company might deny your claim based on negligence. Many insurance providers also offer flood insurance which means you're covered if groundwater rises and floods your home.

While its possible to remove the mold in your home by doing a lot of online research and following all the instructions to the letter, mold remediation services are trained in finding mold everywhere in your home and removing it according to the Environmental Protection Agency (EPA) guidelines. They can identify moisture sources, evaluate the level and quantity of mold growth, contain mold damage to the smallest area possible, and physically remove contamination safely and efficiently.[4]

A flooded home can leave you feeling frustrated, especially when mold is involved, but what can you do? Are you worried about the dangers of black mold to you and your family?

Take back some control with these do-it-yourself mold removal tips.

Follow these three tips to ensure that your do-it-yourself mold removal project will run smoothly and safely.

If the wiring in your home has been affected by mold, youll want to turn off the main power. When youre done disinfecting your home, enlist the help of a professional electrician to make sure its safe to turn the electricity on again.

Check for leaks in the water system before you spray your home down. Rent a hose that allows you to spray a soap and water solution together.

Spray down every moldy item in your home from floor to ceiling.If you havent spent time with heavy cleaning chemicals before, test yourself out by disinfecting a small area of your home to start.

If the fumes affect you too much, hire a professional mold remediator to disinfect the rest of your home.

Mold removal requires you to be as meticulous as possible. After the mold has been washed away, use cleaning pads or a stiff brush to scour each surface.

You can use a commercial cleaner to scrub moldy surfaces after theyve been sprayed, but any non-ammonia detergent will work just as well. Try a mixture of 1 cups bleach* with a gallon of water for a simple, homemade solution. (Update: We no longer recommend using bleach for mold.)

Furniture, walls, floors, ceilings, and heating and cooling registers and ducts must all be disinfected with a solution that has a quaternary, pine-oil, or phenolic base.

To be safe, get rid of a foot extra of drywall above the flooding level. Call in a professional to get any area that you arent able to reach on your own.

Dry each area for at least two days. If you dont, the mold will return.

Soft materials such as rags, clothes, paper and even heavily affected carpet will retain mold spores even after disinfecting and drying. Throw these items away in sealed bags.

When youre ridding your home of mold, the cure can be as dangerous as the illness.

To keep yourself safe from both mold and cleaning solution fumes, keep your home well ventilated throughout the cleaning. Take frequent breaks to get some fresh air.

Buy a mask or a particle remover respirator at a hardware store to protect you from mold spores released during the drying process.

Because respirators dont protect you from fumes coming from disinfectants such as bleach, spend as little time as possible around these chemicals.

Always wear gloves when youre handling anything containing mold and dispose of the gloves when you are finished with your project.

When youre finished doing all you can to disinfect your home, you may want to hire a licensed contractor to check your work.

A professional can help you find any mold that you missed or assure you that your do-it-yourself mold removal project was a success.

Mold Removal: 3 Tips to Do-It-Yourself Mold Blogger

How do I safely deal with moldy materials? If you are sensitive to mold or if the amount of mold is large, consider having another person or professional do the work. Use personal protective equipment, such as goggles, gloves, and an N-95 particulate respirator. A "dust mask" will not protect you from mold. It is also advisable to wear removable protective clothing (such as disposable suits) while handling moldy material, as mold can collect on clothes and be released later. It is important to prevent contamination from spreading from the source area to other areas in the home [see guidelines below]. It is alsoa good idea to ventilate the area you are cleaning to the outdoors during and after the work.

Cleaning non-porous materials:Scrub non-porous materials thoroughly with soap and water to remove mold. We do not recommend using bleach or products that contain bleach. Bleach can be a respiratory hazard and disinfection is not necessary if you have cleaned the material thoroughly with soap.

Removing porous materials:Moldy materials should be sealed in disposable bags or wrapped in plastic and disposed of as normal trash. The moldy material does not need to be treated as hazardous waste. The US EPA offers further tips and techniques for cleaning up mold in homes.

Should You Stay In Your Home During Mold Remediation?

Heres the procedure:

Any leftover bleach and water solution can be easily flushed down the toilet. Rinse out your brushes and rinse off your gloves and boots with the garden hose, and let everything air dry. You can also use this technique to clean siding, as well as sealed brick and patio stones. Note that you should avoid applying the bleach solution in direct sunlight or to unfinished wood. The solution should not be used for aluminum gutters or windows; rinse thoroughly if any contact occurs. You should also test the bleach solution on the area you want to treat in an inconspicuous area before starting your project. Sure, it sounds easy enough, and really, it actually is! Heres a picture tutorial to help you see how its done.

Mold and mildew builds up a little at a time over the winter. Theres less daylight and lousy weather, making it easier to put off dealing with (until you cant any longer!).

Use a large plastic tarp to protect the plants.

To make up 2 gallons of the bleach solution, use 1 cups of bleach. This makes it easier to dip a long handled brush into the solution. Measure water into the bucket and mark volume lines on the outside so its easy to just use the hose to fill the bucket to the correct volume. No guessing as to how much a gallon is!

Wet the surface with a garden hose. When its wet, the discoloration looks even worse.

The less you have to think about what you are wearing while you are working the better. Rubber rain boots and old clothes that you wont mind getting any bleach splashes on are perfect.

Use a long-handled brush to apply (and reapply by just dipping the brush back in the bucket) the bleach solution to the wall.

Some corners really can only be scrubbed with a hand-held brush. The gloves are really nice to have here:

If you have a large area to clean, dont try to do it all at once. To stay within the recommended 5 minutes of contact time, work in smaller sections, rinsing the first area before starting again on the next.

Wow what a difference!
