Called for an estimate- they wanted to charge $150 just for an estimate. Made an appointment to come for 7am- they never showed, did not call. When we called to see what happened they said they had an emergency. No accountability for making people wait and the audacity to charge for an estimate. A simple phone call to let us know and an apology would’ve prevented a bad review. It’s rad the receptionist just slammed the phone when we told them we would not move forward with their services. People need to take off work to wait around and this is their service? No thank you.

Great price 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.))

I was in need of a new hot water heater. I called Buttermark & Sons at 9AM. The person I spoke to was very polite and professional. I was given an exact price that was fair and not an estimate. Within 2 hours they were at my house and replacing the water heater. The job was done quickly. The plumber that replaced it was courteous, friendly, and did a great job. What I thought was going to be a stressful process was pain free. I can't ask for much more.

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. Negative Professionalism
