Wow…I am glad I called Alex at DryHome. I thought I had a mold issue in my bathroom behind the drywall. Alex came out and dug around, checked with his instruments and informed me that it was just the tar/waterbacking and the covering drywall was just not placed properly by my handyman. He was professional, pleasant and even heard that my toilet was running and he fixed that too. I have heard horror stories about mold remediation companies ripping people off. Not that case here — you can't go wrong with his company. I highly recommend.
