Dave was polite, clean, and took the time to explain everything without any upselling or pressure. You can tell they actually care about doing things right. The price was fair, and the whole experience was stress-free. Total time without hot water was less than 24 hours. It's nice to find an honest local plumber in Newton who still answers the phone and shows up when they say they will. Highly recommend!"
