4 years ago, they installed a new boiler for me. The other day, it refused to light. I called, they showed up in a half hour. D. did diagnosis, didn't find the problem. Brought in the big guns, few minutes later, problem was diagnosed - a defective National Grid regulator (Not Buttermark's responsibility or business to service).
He was correct. It was only marginally bad, good enough to keep the water heater running, not good enough to run the boiler (The most difficult type of failure to diagnose and fix). Charge? "$0, boiler was a new system."
That's outstanding customer service and standing behind the sale.
((National Grid came in and replaced the regulator, all's good now.))

Donald from Buttermark Plumbing came to my mom’s house to make several repairs that were desperately needed. She has been a customer for years. Donald was professional, kind and extremely helpful and fixed everything perfectly. Donald is a superstar and a great asset to the company. Thank you for everything!!

The person who takes calls for this company, Angela is one of the rudest, most condescending people I have ever encountered. I’ve been a client of Buttermark plumbing for 7 years (yearly fire sprinkler inspection) and when I called with a leaky water heater issue she promptly told me they could not help - end of conversation. She had the audacity to ask what fire sprinkler inspection had to do with a water heater leak.
Nothing babe, but as a “professional” in the plumbing game you might have suggested what my next step might be.

Going on third day of telephone calls that I made. They don’t call you back. “Just follow protocol “. I tried talking nice but all I got was rudeness. Going to use someone else no matter what it costs.

Just got off the phone with Buttermark trying to schedule a potential repair. Rude as hell. Like I was bothering them. Never again.
