Due to condensation, high humidity and obstructed soffit vents, Mold had overtaken the lower 4ft off attic sheathing. The remediation was made more difficult due to the furnace being in the attic, and the tubular ductwork covering the attic floor everywhere. This job was done in a day with 2 technicians and Bob DeBoer as project manager. Air filtration continued for 24 hours. Client was very pleased with the 10 year transferable warranty.
