I can't comment on their work because I can't get them to return a phone call. I have left at least 6 messages over three weeks. I had a neighbor who was very pleased with their work, but I'll find another company because if this is how they treat a prospective customer, I can only imagine what they will do (or rather, won't do) if something goes wrong. After I read the other comments, this seems to be norm rather than the exception.
