If your walls are turning black in a corner, it’s no accident: find out what it really means (and how to fix it) (Page 2 ) | April 23, 2025

Preventing Mold from Returning

Once you’ve cleaned the affected areas, the key is to stop it from happening again.

Make sure your home is properly ventilated. If necessary, install or improve ventilation systems like extractor fans in kitchens or bathrooms.

Keep track of humidity levels with a hygrometer—an inexpensive tool that helps you ensure your indoor air stays between 40% and 60% humidity.

Consider using anti-moisture paint on walls that are prone to dampness. While it’s not a complete fix, it adds a layer of protection.

If you suspect deeper issues like leaks or insulation problems, it’s wise to contact a professional. Sometimes what you see on the surface is just a symptom of a larger hidden issue.

What If the Stains Keep Coming Back?

If mold reappears despite your efforts, it’s time to dig deeper.

Inspect your roof, gutters, and walls. The root of the issue could be hidden leaks or faulty insulation. There are also specialized treatments for rising damp, including resin injections and anti-saltpeter solutions for walls showing white or crumbling spots.

Hiring a certified moisture expert can save you from bigger repairs later. If you’re renting, be sure to notify your landlord—mold can be a serious health concern and should be addressed quickly.

Conclusion

Black spots on your wall may seem small, but they can be signs of a larger moisture issue. By staying alert and taking quick action, you can control the situation and create a cleaner, healthier living space. A bit of awareness and maintenance can go a long way in keeping your home mold-free.
