Tenants and landlords should try to work cooperatively to investigate and correct moisture problems and remove mold growth. If mold can be seen, if a musty odor is present, or if there is a good reason to believe health problems are being caused by mold, a careful inspection of the home should be conducted. Attention should be paid to hidden areas, such as plumbing access areas, crawl spaces, behind mirrors, attics, behind furnishings, closets, and cupboards. Correcting a mold problem properly requires fixing the moisture problem, removing the mold, and keeping the home dry in the future. Mold growth should be cleaned from (non-porous) surfaces such as concrete, metal, glass, tile, and solid wood. Mold growth is difficult to clean on absorbent (porous) surfaces such as drywall, carpet, fleecy furnishing, and insulation. These moldy materials should be discarded. Personal belongings can be kept if there is no mold growth in them. They may need a deep cleaning to remove mold particles that have settled in the fabric. Merely applying a chemical, like bleach without removing the mold growth is not an effective solution; neither is simply painting over the problem. There are numerous private contractors who specialize in inspecting or cleaning mold in homes. Where problems cannot be identified or safely remediated, the landlord may want to hire a residential service provider. In addition, certain moisture problems may be covered under property or renter insurance.
