I used them to remove mold in the house. The problem is with the finish and clean up. Eli’s crew pretty much destroyed the windows, they left some anti mold stuff on the windows and frames. They came back several times to take the stuff off, but they ended up stripping the paint off the frames. I told them goo b Gone works just fine, but they needed to work harder to get the stuff off, Eli has said, on muliple occasions, they would come back and fix everything, but 6 months later, they still haven’t.
