Today we started a mold remediation job on an 8,000 square foot home. The home is a 3-story home over a basement. We did the initial environmental inspection a few weeks ago. The reason for the inspection is because an occupant of the house is being treated for mold toxicity and her doctor referred us to evaluate the home. The home is extremely nice and well built, but we still found issues. They have lived in the home for almost 20 years, and they were the ones that had it built so they know the history of the home. There is only one area that they knew of where water had intruded. It was a chimney flashing leak, and the water damage was evident in the 3rd floor bedroom. Due to the type and level of mycotoxins the lady tested for, I expected to find mold growth from xerophilic molds (low moisture). Xerophilic molds will grow in sustained elevated humidity. So, off to the basement I go. We found mold growth on furniture, unfinished drywall, and other contents in the basement. The levels in the spore trap tests in all the rooms in the basement were high. The main level has a laundry room that shows a bit of moisture in the ceiling with a thermal camera. You can see the red in the picture on the camera. That area was verified damp with a moisture meter.
There were several other small issues we found during the inspection, so we wrote them up and sent the report to the customer. Which brings us back to today. We started the job and today was demolition day! The small amount of moisture in the laundry room turned out to be a significant amount of mold. This area has a leak from the bathtub drain and is still wet. We are going to remove the cabinets so we can get the rest of the drywall out and then set a dehumidifier up in the contained area to dry it out. We’ll treat the mold later in the week using procedures from the ANSI/IICRC S520 (Standard for Professional Mold Remediation). Will provide an update once the job is complete.
