STP Plumbing is a plumbing company based in Blackstone, Massachusetts. Its website says it has been in business for 16 years and lists water heater repair and replacement, tankless water heater work, gas hydronic heating system repair, boiler installation and radiant floor heating among its services. The website also states free estimates and 24/7 emergency service. Its Massachusetts plumber license is active on the state registry. One reviewer returned from vacation to no hot water. Steve tried to get a replacement part for their old combo system and, when that wasn't possible, walked them through other options; they ended up with a new gas boiler heating system and water heater, and in the meantime he left the family with a 30 gallon hot water tank. The reviewer said Steve and his team installed the new system in their 150-year-old house in Franklin, MA without issues. Another reviewer's water heater stopped working and was leaking. Steve showed up, provided options, gave a quote within 10 minutes that was half of the first company's estimate, and by mid afternoon a brand new water heater was installed. In another review, Steve replaced a hot water tank and walked the customer through all of the options along with associated pricing. Steve and Will responded to one reviewer's plumbing emergency in less than an hour and later returned to install a new hot water heater. For another household, Steve took a water sample, gave a quote on a Thursday and installed the entire water filtration system the next day. Chris, described in one review as the master plumber, and his technician Jack replaced an outdated basement toilet in a reviewer's mother's home. Another reviewer said STP Plumbing handled a pipe repair and a new toilet installation, explaining everything along the way.
⭐⭐⭐⭐⭐ Outstanding service! The BEST! Steve and Will responded to my plumbing emergency in less than an hour and had me back up and running quickly. They later returned to install a new hot water heater, and the entire experience was exceptional. They were on time, professional, neat, knowledgeable, and their pricing was very reasonable. It’s refreshing to find contractors who truly care about doing quality work. And I would be remiss if I didn’t mention Beth in the office, who quickly made phone calls to address the emergency! She was compassionate and really calmed my nerves during a very stressful situation. I highly recommend STP Plumbing to anyone looking for honest, dependable plumbers. Five stars all the way!
STP Plumbing recently provided me with excellent service for a pipe repair and a new toilet installation. They were extremely helpful from the moment I called to see if someone could come out to the time they finished the work- thoroughly explaining everything along the way. They were very knowledgeable, professional, and kind. I’m already hoping to have them come back for some additional work.
I had an excellent experience with Chris from STP. He provided great work at a great price, showed up on time, and was thorough from start to finish. Chris was professional, friendly, knowledgeable, and took the time to explain everything clearly. The quality of the plumbing repair and service was outstanding, and the pricing was fair and honest. I highly recommend STP to anyone looking for a reliable, affordable, and trustworthy local plumber. Great guy, great service, and a great overall experience. If you want it done right, this is the guy to call.
I had an outstanding experience with STP Plumbing, who recently replaced an outdated basement toilet in my mother’s home. From the first interaction, Beth, the dispatcher, was incredibly informative and set a positive tone. She recommended Chris, their master plumber, and he, along with his technician, Jack, met and exceeded my expectations!! They were honest about pricing and thorough in explaining all of my options. And efficient!! I felt completely at ease, knowing they had our best interests at heart. Their transparency and professionalism truly stood out though. I highly recommend STP Plumbing! Well done, STP!! 20 out of 10!!
We had a great experience with STP plumbing! Steve is very responsive and knowledgeable, and is passionate about what he does. He designed a water filtration system for our house which works perfectly, and is an upgrade I wish I had done years ago... Steve took a water sample and gave us a quote on a Thursday, and then installed the entire system the next day on Friday! The whole process was very efficient, and the equipment he installed is top quality.
