Andy worked with our roofer so that we could save a little by having the exhaust fan vent installed while the roof was off. He came exactly when he said he was going to come, and finished the job exactly when he thought he'd be done. I had even added an extra task (moving the half-bath light). He's a really pleasant, professional man who knows his stuff and guided me on getting the appropriate exhaust fan. Even adding the extra task, his price was lower than the estimate, which is always a happy surprise. I would hire him again in a minute.
