Factors affecting the cost of mold abatement include how early the mold is detected and treated.

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.

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.

Install vapor barriers to seal out ground moisture and wrap pilon supports.

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:

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.

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.
