How To Control Mold In Kitchens

Mold needs moisture to grow. Keeping your kitchen area dry will help to control the mold. You can also use a mold-resistant paint on the walls and avoid having carpets and rugs on the kitchen floor, especially in front of the sink.

Laundry Rooms

The washing machine and sink create moisture that can cause mold in the laundry room, and wet clothes often contribute to the overall wetness of the area. Even running your dryer with the laundry door closed can lead to high humidity levels in the room. Laundry rooms are often considered a clean space, but when the relative humidity is too high, mold is often a problem.
