The level of customer service they showed was appalling. I had them come out to quote my siding, which was a small portion of the house, and trim/insulation. The quote was triple another quote from another reputable vendor and didn't show any quantities. When I asked them to confirm the scope of the project, because their bid did not show any quantities, they said no, but don't worry because there's no way they're wrong, since they've been doing this for long, and I'd just have to trust them. Uh, no. There is no way anyone should sign off on a bid from a vendor like this that refuses to quantify their estimate. Always get three bids, too.
