A homeowner in Monona, Wisconsin contacted Pure Maintenance Wisconsin after being referred by his health practitioner. Blood testing had revealed high mold levels in his system, and while there was visible mold growth on the windows throughout his home, the underlying sources were not immediately obvious. An investigation was needed before any remediation could begin.
Air sampling inside one of the HVAC units revealed a staggering reading of 112,160 spores per cubic meter — not ideal. Inspection of the crawlspace beneath the home, despite having a concrete floor, revealed significant fungal growth on the wood structural components. Humidity readings throughout the home were consistently elevated, and the home's location on a lake compounded the problem — lakefront properties in Wisconsin carry an inherently higher ambient humidity and spore load year-round.
The cause became clear. The home had not been dehumidified, allowing moisture to accumulate over time. Fungal growth in the crawlspace — driven in part by moisture releasing from the concrete slab as it dried — had been distributing spores throughout the home via natural air movement and the HVAC system. The elevated indoor humidity had also caused persistent condensation on the wooden window frames, creating secondary mold sources in virtually every room. The windows, the crawlspace, and the HVAC unit were all connected manifestations of a single root cause: chronic high humidity in a lakefront home without active moisture management.
This is precisely the type of scenario our patented vapor technology is designed to resolve. A one-day treatment brought the spore level from 112,160 spores per cubic meter to 0 in all three post-remediation samples taken throughout the home.- including the same location where the original 112,160 spores/m3 air sample was taken. Fungal growth on the windows and crawlspace wood was cleaned as part of the same process. The homeowner can now move forward with treatment for his mold toxicity with the confidence that his home environment is no longer working against his recovery.
