After dealing with a roof leak, our neighbors in Winterville discovered mold in their home, and their pulmonologist actually recommended that they call us to have the mold safely remediated.
Inspecting for Mold and Asbestos
The leak occurred around the exhaust vent for a built-in fireplace insert. Water ran down the exhaust duct and wet the ceiling and wall drywall. The fireplace was installed in a corner of the living room after the house was built. A new wall was framed up that ran diagonally across the corner of the room. Therefore, drywall on the new wall as well as on the original walls behind it was affected by the leak.
Mold was also found on the ceiling drywall, ceiling joists, wall studs and subfloor. The house had a basement, so we were able to inspect the underside of the subfloor and determine that mold was not present on the bottom of the subfloor.
We sampled the drywall, drywall joint compound and ceiling texture for asbestos. The lab results were negative for the presence of asbestos, so we were able to proceed with mold remediation, rather than asbestos abatement and mold remediation. Asbestos in drywall, drywall joint compound and ceiling texture is more common than you might think.
The Mold Remediation Process
The affected area was confined to the living room, so we built a containment to prevent the spread of mold spores and dust to other areas of the house. We utilized a ZipWall barrier system, 6 mil polyethylene sheeting, spray adhesive, painter’s tape and duct tape to build our containment.
Due to the small size of the contained area, we placed our HEPA-filtered negative air machine outside the containment and connected it to the containment using additional polyethylene sheeting. We ducted the exhaust out a window using poly tubing, and constructed the containment with a flap door to provide makeup air.
Our mold remediation staff wore personal protective equipment consisting of disposable suits with built-in boots, gloves, half-face HEPA-filtered respirators and safety goggles. Drywall was removed inside the containment and sealed in 6 mil trash bags to be carried out of the house.
Once all water and mold damaged drywall was removed, we cleaned the ceiling joists, wall studs and subfloor with a mild detergent solution. Then we HEPA-vacuumed all surfaces inside the containment and treated the affected building materials with Concrobium Mold Control before removing the containment.
The Remediation Outcome: Safe, Contained, and Clean
Mold spores and dust were contained to the work area and were not spread to unaffected areas of the home. Our customers were left with a clean area, free of mold, and ready for reconstruction!
