Basement Mold Removal in Fife, WA

Why is my lower level always damp?

Ground conditions play a big part. Fife is a tideflat community on low, flat land extending from the Port of Tacoma, and in some parts the water table is only 10 to 15 feet below the surface. Southern portions of the city lie in the Puyallup River floodplain. A basement, sunken room or lower-level storage area dug into that ground sits close to wet soil for much of the year, and the long Puget Sound rainy season keeps it that way. Condensation adds to it: cold walls, little ventilation and moist indoor air are a reliable recipe for mildew in winter.

What should I do if the water keeps coming back?

Treat the water first and the mold second. Clean gutters, extend downspouts, check that soil slopes away from the house and look for plumbing leaks. Run a dehumidifier to keep humidity under 60 percent, as EPA suggests. Then remove and clean the mold: EPA says porous materials such as carpet may have to be thrown away once moldy and warns against painting or caulking over growth. In a high-groundwater area, ask a contractor whether interior drainage or a sump is realistic for your house. Fife's municipal code includes a flood damage prevention chapter administered by the community development director, so ask about it before major rebuilding. Building permits come from the City of Fife Community Development Department.

I rent an apartment with mold in the lower level. Who helps?

Start with the landlord, in writing. Washington landlords must keep units weathertight and in reasonable repair, and state law sets times for starting repairs after written notice. The Tacoma-Pierce County Health Department has said it does not have regulatory power over rental housing issues, though it has seen an uptick in complaints such as mold; its healthy housing page has tenant resources. This is general information, not legal advice.
