"Pete is a great guy. I booked a reservation from Home Advisor to clear a clogged drain and to repair a possibly burst pipe. He responded promptly and arrived on time. Very polite and very professional. He listened very carefully and explained thoroughly about the issue. He left no mess when the job was done. He brought tarp and his slippers and took out the trash! The price is very reasonable. Very satisfied and strongly recommend."

"Dana knew right away that the problem was with the air handler. As it turned out the condensation drip pan had filled up and tripped the over flow switch. PTL for that switch. Dana drained the pan and cleared the drain. All ok now. Thanks for the help. Nice job Dana."

"I was making Thanksgiving dinner and created an impenetrable clog in my kitchen sink drain. Two types of drain cleaners and my pathetic snaking skills did nothing all day Friday. I called A.M. Botte at 8 AM Saturday and their Tech, Mel C., was here in fifteen minutes! He did an amazing, professional job and even gave me a veteran discount (I was pleased to learn that Mel is also a veteran). I would recommend A.M. Botte to anyone needing top-quality service."
