Mold Removal – Wisconsin Department of Health Services

Before cleaning mold in your home, first understand why mold is there and fix the problem causing the mold growth. This will require a thorough inspection. Fungi (or mold) need a source of moisture, a source of organic matter, and proper temperature. Areas inside your home that have poor air movement and a source of moisture are likely areas for mold growth.

Once the source of the water intrusion and the food source have been found, they should be addressed to prevent future mold growth. If this is not done, mold may return. You must either eliminate or ventilate the source of water or moisture. Affected building materials, such as carpets or drywall, may need to be replaced.

Testing for mold is generally not necessary. If you can see and smell it, you have a mold problem. However, it is recommended that you do have a thorough inspection to determine the cause of the mold growth.DHS recommends that you hire a consultant specializing in building assessments to evaluate your entire house.

Here are IAQ consultants and mold remediation contractors whose primary focus is mold:

Occasionally, mold can be found in the bathroom, on a windowsill, shower curtain, or wall. This mold can be wiped off the surface with a damp cloth and cleaning agent (such as window or bathroom cleaner). Preventing mold growth requires controlling the moisture source, which may be as simple as using a dehumidifier or fixing a simple leak.

For larger mold problems (about 10 square feet), follow the three (3) phases below. (If you feel that the following guidelines are too vigorous, you should contact a mold contractor to complete the cleanup.)

CAUTION: The bleach solution is irritating and harmful to the skin, eyes, and clothing. Avoid direct contact with the bleach by wearing rubber gloves, respirator and goggles during the entire mixing and cleaning process.
