Job completed for Edelhar, Sam

The customer contacted us for professional mold mitigation after discovering severe, widespread microbial growth spreading across a textured plaster bedroom ceiling. The fungal colonization concentrated heavily around the HVAC supply vent, indicating that a hidden condensation defect or duct insulation failure inside the ceiling cavity was introducing persistent moisture into the drywall structure and creating an ideal environment for mold amplification.

We executed a systematic containment, source investigation, and structural remediation strategy to permanently resolve the mold issue. First, we established containment boundaries and carefully cut out the heavily contaminated ceiling drywall sections to safely access the floor joist cavity. Upon exposing the interior framing, our team diagnosed the root cause: an exhaust fan housing and its flexible aluminum duct line were improperly insulated and buried loosely under fiberglass batts, creating heavy thermal condensation that wicked into the surrounding structure. We performed a precise mechanical cleaning of the exposed wooden joists, subfloor sheathing, and HVAC components using HEPA vacuums. Next, we applied an industrial-strength, EPA-approved antimicrobial biocide across the entire open cavity to eradicate deep-seated fungal roots and protect the structural timber from future colonization before closing the area back up for reconstruction.
