Mold removal
Attic mold removal
Attic mold usually grows on roof decking from condensation, poor ventilation, bathroom fans vented into the attic, or roof and AC leaks. Removal cleans or treats the decking and rafters, and the ventilation or moisture source is corrected so it doesn't return.
In hot, humid regions, ducts and air handlers sweat in the attic. In cold regions, warm, moist house air leaks into the attic and condenses on cold roof decking in winter. Disconnected bath fans and blocked soffit vents cause growth everywhere.
Attic mold is often found during a home inspection. It rarely affects living-space air the way wall mold does, but it can damage decking and is flagged by buyers.
