Date of Assessment: June 30, 2021
The cove base and several square-feet of floor tile were removed as Building Maintenance was aware and had visited the site prior to the Office of the Environment.
Black staining was observed on the plywood sub-floor which was also soft and flexible as noted above.
Mold growth was observed on the drywall in the location where the cove base would have been.
Building Maintenance removed and replaced the damaged sub-flooring and the mold impacted drywall. During the removal, the cause of the damage was found to be termites. The repair work was completed on July 30, 2021.
