In December 2025, Pure Maintenance Wisconsin was contacted by a Madison condominium association after a water intrusion incident caused significant mold damage in a basement unit. A neighboring owner had used a hose that allowed water to leak into the affected condo, and what followed illustrated exactly why thorough investigation matters more than a quick fix.
The condo owners noticed visible mold in their pantry and began experiencing respiratory symptoms. They hired a remediation company, but that company only removed a small, obvious section of affected material — leaving baseboard trim in place and the surrounding areas uninvestigated. When Pure Maintenance Wisconsin arrived, it was immediately clear the water damage likely extended well beyond the pantry and behind the adjacent kitchen cabinets. Air samples taken behind the cabinet wall confirmed high mold levels in that concealed space. An air sample of the interior living area revealed hundreds of thousands of spores per cubic meter in a single reading — far exceeding healthy limits. The residents had been breathing that air every day.
Pure Maintenance Wisconsin removed the wallboard and insulation behind the cabinets as well as the flooring underneath. Direct cleaning and direct sanitation was performed where needed, followed by a full treatment with our patented vapor technology throughout the unit.
Spore counts went from 169839 spores/m3 before remediation to 119 spores/m3 post remediation. Within days the residents' respiratory symptoms disappeared. Four months later those symptoms have not returned. A permanent resolution to the mold problem in this Madison condo was found — not through a partial fix, but through a complete one.
This case is a clear example of why incomplete remediation can be worse than no remediation at all. It creates a false sense of resolution while leaving residents exposed. Air sampling behind walls and baseboards — not just in visible areas — is what reveals the true extent of a mold problem.
