"Bill from WBI was the first to contact us and the first to give us a quote on the insulating of the attic and crawl spaces of our old farmhouse. The price was very fair for the professional quality of work we received. Bill is a very honest, competent, hard-working professional. He got the job done very quickly, and we are beyond pleased with the work he did for us. We can't say enough good things about WBI, and we highly recommend them!"

"They've maintenanced my furnace before I required a new one and they've always maintenanced the new one since I got it replaced about 3 years ago. Very easy to work with. I think I've been using them since 2008."

"We had a guy come out and assess our insulation and he was kind of creepy. The way he talked, the way he went up in the attic and grabbed a handful of insulation, showed us what was there and got it all over the couch and the floor, and he ended up telling me that he didn't think that I needed anymore insulation. I guess he was honest and I was a bit creeped out. He didn't make a bid because he didn't think I needed any more insulation. I'm pretty certain that we would not call them again."
