Causes Of Mold In Homes/Basements And Quick Solutions

Whenever a green mold (or other colors) shows up in your basement, then you should check the root cause. Because if you don’t, other molds may still return even after you’ve gotten rid of them.
Molds in basements are caused by a lot of things, which,  thankfully, can be fixed.

1. Molds can grow on wet clothes left on the floor – have these clothes washed and stored.

2. Roof or pipe leakage – identify the leaking areas and take the right step to stop the leak before mold starts growing on them.
3. Condensation is one of the biggest causes of mold – molds develop faster in cold surfaces. Concrete floors and metal pipes may cause condensation. Resolve this issue.
4. Lack of proper ventilation– Molds thrive in steam because it has the necessary humidity level for them to survive. Use an exhaust fan or open the windows to improve ventilation.
5./Molds thrive in high humidity– by that I mean humidity above 65%. You’ll need a dehumidifier to achieve this. 
Mold growth is due to continuous mold problems and to get rid of them you must fix the sources where they came from. While these are not expensive repairs, they’ll create a healthier life for you and your family.
