FAQ

I found mold in my basement. Is waterproofing the answer?

Direct answer

Waterproofing addresses the cause; remediation addresses the existing mold. Mold needs moisture, so a chronically wet or damp Cincinnati basement will keep growing it until the water and humidity are controlled. Fix the moisture source first, then remediate, or the mold returns.

More detail

Mold and basement moisture are cause and effect, and the order of operations matters. Mold needs moisture to grow, so a basement with chronic seepage or high humidity will keep regrowing mold no matter how many times the visible growth is cleaned. Controlling the water and the humidity is the durable fix; remediation of existing growth is a separate step that only lasts if the moisture source is closed. For a Cincinnati basement, that usually means some combination of interior drainage (to stop liquid seepage), encapsulation with a sealed vapor barrier (to stop ground-moisture vapor through the slab and walls), and a dedicated dehumidifier (to hold relative humidity down in the Ohio River valley's humid summers). Once the basement is dry and humidity is controlled, existing mold can be remediated and it stays gone. Waterproofing is our lane, not mold remediation, so for significant existing mold we recommend addressing the moisture with us and the existing growth with a qualified remediation professional, in that sequence. The reason we are emphatic about sequence is the number of Cincinnati homeowners who pay for remediation first, watch the mold come back within a season because the wet source was never fixed, and pay again. Note also that mold is its own inspection and disclosure issue at resale, distinct from the water finding, so a basement with both a moisture problem and visible mold has two items to clear before listing, and the moisture fix has to come first for the remediation to hold.

    Moisture control is a core indoor-air-quality issue, and sealing the slab and sump while waterproofing also reduces radon entry paths.

  • MSD Greater Cincinnati

    Sump pumps and foundation drains may not discharge into the sanitary sewer; combined-sewer neighborhoods have backwater-valve and basement-protection programs.

  • Basement Health Association

    Interior perimeter drainage to a sump is an established method for managing hydrostatic seepage in below-grade spaces.
