There was a plumbing leak and the repairs were all done. The wall was put back together and painted. The house looked ready for the sale… but the infrared camera found the wet insulation that was still in the wall and was never removed during the repair process. Whoops… This could be a source of mold and cause the sheetrock to start falling apart after a short period of time. The buyer was really glad this was found before they purchased the house, so it could be repaired correctly.
