Mold Prevention and Remediation in Homes and Apartments

Understanding Mold

Mold is a common household issue, especially in damp and humid environments. It can cause health issues, particularly for those with respiratory problems, allergies, or compromised immune systems. Mold prevention and timely remediation are key to maintaining a safe and healthy living space.

There is no test for mold.

If you see mold, or there is a musty smell in your home, you can assume mold is present somewhere. The Bridgewater Health Department cannot test for mold, and the CDC does not recommend routine mold testing. There are no state or federal mold standards for airborne concentrations or mold spores, so testing results cannot be compared to a recognized “safe level.”

1. Control Humidity Levels

• Keep indoor humidity below 60%, ideally between 30% and 50%.
• Use dehumidifiers if necessary, especially in basements and bathrooms.
• Refer to the EPA’s Guide to Indoor Air Quality for additional information.

2. Ventilation

• Use exhaust fans in kitchens and bathrooms to remove moisture.
• Make sure appliances such as dryers vent outside the home.
• Open windows and doors on dry days to improve air circulation and reduce moisture.

3. Fix Leaks and Water Issues

• Promptly fix any leaks in the roof, windows, or plumbing to prevent water from accumulating indoors.
• Address flooding issues immediately.
• Check your home’s foundation for cracks where water might seep in.

4. Regular Cleaning

• Clean and dry areas prone to moisture, such as bathroom tile and window sills, on a regular basis.
• Use mold-killing products, such as a bleach solution or commercial mold cleaners, on surfaces that tend to stay wet.

5. Monitor for Signs of Mold

• Mold may appear as black, green, or white spots on walls, ceilings, or floors.
• Musty odors can also indicate hidden mold growth.
• Regularly inspect damp areas such as basements, attics, bathrooms, and areas around plumbing fixtures.
