John Stewart came to fix the fallen piece of siding and was really great about it. He came very quickly after we first made contact on Thumbtack and fixed it on the spot. He inspected the entire house, found all the loose siding and nailed everything down.
He also found a couple of other non-related roof problems, which may have turned into water issues, and we arranged to fix those as well.
Got all this done at a very reasonable price, compared to what some of the other roofing companies were quoting just to do the one fallen piece of siding.
