Property Type: Residential Basement

Location: Cuba City, WI

Primary Concern: Musty odor, allergy concerns

Key Findings: Elevated relative humidity, confirmed spore count

Recommendation: HVAC service, dehumidification

The Problem: Homeowner noticed a recurring musty odor in the basement after heavy spring rains

The Assessment:During the on-site analysis, I focused on identifying potential moisture pathways in the basement's lower-level finish. Using a pinless moisture meter, I performed a systematic grid-check of the North and East basement walls.

While the drywall surface appeared visually dry to the naked eye, the meter readings indicated elevated moisture content (exceeding 18% M.C.) in the drywall panels directly behind the HVAC supply plenum. To verify the ambient environment, I utilized my thermo-hygrometer to record an indoor relative humidity of 64% at the time of inspection, which is above the recommended indoor threshold for this region. By isolating these specific zones, I was able to identify that the moisture accumulation was isolated to the area of thermal bridging near the HVAC ductwork, rather than a widespread foundation leak.

The Findings: The pin less meter detected elevated moisture levels in the drywall behind the north wall, while air sampling confirmed the presence of Aspergillus spores.

The Solution: Explain the "Next Steps" you provided, even if you didn't do the remediation yourself. This reinforces that you are the expert advisor.
