The serviceman was clearly extremely experienced. He was very friendly and courteous to me and respectful to my home. He restored things nicely after the work was done. He didn't act bothered at all that I wanted to observe while he worked and he gave helpful answers to my many questions. I'm guessing this is a rare find in a business that has to deal with so much crap (pardon the pun). I'll definitely use them again (hopefully unnecessaryf.)
