Recent Review: George showed up on time (a little early actually). He cut a bigger hole in the drywall around the problem hole. The back of the wall were all dry with no mold present. George then repaired the drywall with a drywall piece from his supplies, caulked an smoothed the installation, sprayed it with the popcorn finish spray, used the paint I had left over from the builder and one of his brushes. The result was excellent - couldn't even see the patch. Then he sealed a couple of corners in the shower, inside and outside, that had led to the problem in the first place. All done in an hour and a half, including the cleanup.
