a. Identify the Source of Moisture
Before cleaning, find out where the moisture is coming from. Look for leaks, check insulation, and assess ventilation. Solving the root cause is crucial; otherwise, mold will keep coming back.
b. Improve Ventilation
- Use exhaust fans in kitchens and bathrooms.
- Open windows when possible.
- Use a dehumidifier in damp rooms.
c. Insulate Problem Areas
Adding insulation to corners that are prone to condensation can help prevent thermal bridging and reduce mold-friendly conditions.
d. Clean the Mold Safely
If the area is small:
- Wear gloves and a mask.
- Use a mixture of white vinegar or baking soda with water, or a mold-specific cleaner.
- Scrub the area thoroughly and dry it completely.
If the affected area is large or recurring, it’s best to hire a professional mold remediation service.
5. Preventing Mold in the Future
- Regularly check for and fix leaks.
- Use mold-resistant paint, especially in humid areas.
- Keep indoor humidity levels between 30–50%.
- Clean and dry water-prone areas like bathrooms and kitchens often.
6. When to Seek Professional Help
If:
- The mold covers more than 10 square feet.
- You experience persistent health issues.
- The mold keeps returning even after cleaning.
- There is hidden mold inside walls or under flooring.
Call a mold remediation expert who can assess the problem and safely remove it.
