Mold can grow anywhere there is moisture. If there is mold in your home, you must clean up the mold and fix the water problem. If you don’t fix the water problem, mold will come back.
Note: Arlington County is unable to inspect, test, or remove mold, or to provide legal advice.
Indoor mold can cause health problems for some people, especially children and people with allergies or asthma. Common symptoms are cough, runny nose, wheezing, and sore throat. If you are worried about mold and your health, talk to a healthcare provider.
In most cases, you do not need to test for mold. If you can see or smell mold, you have mold.
- LOOK – Do you have leaks, standing water, water damage, or water marks? Have you had recent flooding? Look behind and underneath furniture and other materials in suspected areas. Mold on surfaces can look fuzzy or slimy and it can be brown, black, green, white, or a variety of other colors.
- SMELL – Sometimes you can’t see mold. If you smell an earthy, musty smell in a certain area of your home, you may have mold, especially if you have recent water damage or moisture.
Water and moisture are necessary for mold. Here are some things you can do to prevent mold:
- Use air conditioners (A/C) or dehumidifiers, especially in humid Virginia summers! If you do not have A/C, use fans.
- Use bathroom fans during and after baths or showers.
- Clean up spills and leaks quickly, especially on carpets.
- Use kitchen fans when cooking or running the dishwasher.
- Do not use humidifiers unless there is a medical reason to use one.
You can clean small areas of mold (less than 10 square feet):
- Protect yourself with rubber gloves, goggles or eye protection, a N-95 respirator, and long sleeves and pants.
- Scrub mold off hard surfaces with dish soap and water. Allow items to dry completely.
- Throw away moldy materials with tiny holes or openings (e.g., dry wall, carpet, upholstery, insulation). These materials are hard to clean.
- Do not paint or caulk over mold. Clean the mold and dry the surface first.
- Note: No matter how well you clean mold, you need to fix the water problem or mold will return!

For large areas of mold (more than 10 square feet), it is best to get help from a professional.
How do I know if the mold is gone?
The best ways to tell if mold is gone are:
- You found and fixed the water/moisture problem
- You cleaned or threw away anything with mold on it
- You do not see or smell mold
