Ask for a written diagnosis, scope, parts, and price before authorizing major repairs or replacements, and verify the claimed Massachusetts master plumbing license. The company appears suited to plumbing, boiler, heating, gas, and water-heater work, including emergency calls, when the proposed work is clearly documented.
Knowledge and helpful. Will hire again.
$895 It was very efficient in troubleshooting my heating issue,by diagnosing I needed componets for my furnace . Sam did apretty good job my was nisce and toasty.
My heat was not working. Sam immediately responded and was able to come within hours. He diagnosed the issue. found the necessary part, and installed it all same day. Even better he was extremely nice. Iâ ll surely be using Sam for all my heating and AC servicing moving forward.
My boiler was working fine; they came to service both units. The first time they turned the first floor on, it worked through the night. The next day, they heard a bang, and water began to run out of the boiler. Now I have to spend $1100 to get it fixed, and the plumber is not 100% sure if this will fix it or if I will need a new boiler. After seeing some reviews, I decided to call another plumber. Sad!
Sam was very prompt at contacting me back and was able to schedule me very quickly. He was on time, really efficient, walking me through the issue and discussed options, as well as being reasonably priced.
