We had a moisture issue in our basement: damp smell and small spots of mold. My husband is DIY guy, but all his attempts to fix didn't make it better, in fact over time it got worse. So we searched for an expert. We got couple of estimates and choose doctor rooter to go with. Bill was great, answered all our questions and phone calls,even gave us tips how to keep the basement warm at winter time. They fixed two cracks in the basement wall, had to dig deep enough, it was nearly the bottom of the footing level. The whole job complete in two days with minimum disruption and total clean up after themselves. I would definitely recommend this guys.
