We are a father and son business. we are both licensed and insured in MA. We offer free estimates on any job. We work with some great contractors and electricians so we can provide start to finish remodels and installs. Heating is our specialty. We also handle all gas work needed heating and other appliances.

"Poor quality work caused sewage leak in basement. Ryan Plumbing installed all new plumbing for a new 2nd bathroom in our house. 1 year after the project was complete the newly installed PVC pipe for the waste line fell out of an elbow joint and dumped waste into our basement. I called Jeff Ryan to repair it because I was hoping he would take ownership of his work. We talked about why it happened and he said that the overlap of the pipe within the elbow joint had only been half of what was needed (0.75 inch vs 1.5 inch). He apologized and did not charge for the repair. However, a couple of days later when I asked Jeff to pay for the $1,600 cleanup cost, he fabricated a new story about the problem being caused by a clog and not his quality of work."

WE INSTALL BOILERS. And we do it well! Commercial & Residential services available for: Plumbing, Heating & Gasfitting, BOILERS, Radiant Heating, Water Heaters, Solar Heating, Kitchens & Bathrooms. We've been providing these services for a VERY LONG TIME and would love to provide our expertise and attention to detail with your next project. Give us a call today! P.S. I always return emails

"Ray quoted a replacement natural gas steam boiler at a price well under what both Boston Standard and Sila quoted me. Well under meaning close to 20% less. Ray is very responsive by phone and he shows up when he says is going to. Ray had done maintenance on our old boiler prior to this complete replacement. He actually performed maintenance on our old steam boiler, unlike when Boston Standard and Sila did maintenance they would simply turn it on and made sure it fired up. When Ray came and did maintenance after the 4 years we had both Boston Standard and Sila maintain our boiler he disassembled and cleaned out the incoming piping, replaced the glass water tube level, added a skimming drain, skimmed the boiler, etc. The prior 2 companies never did that level of work and it was in bad shape. In addition, not many technicians have knowledge of steam boilers these days even though they are still quite common in New England homes. Back to the new replacement boiler that we just had completed. Ray did a fantastic job on the installation. I really couldn't ask for better service. He was timely and efficient (we had our heat back on the same day), explained everything thoroughly (usually multiple times for my benefit) and has called and come back to check on everything a couple times since the installation. He's really gone above and beyond. We have 1-pipe steam radiators and he understands the intricacy of steam quite well. Ray also did all the plumbing when we had our kitchen renovated. He was our contractor's choice for a plumber (which is how we found Ray) which gave him that extra credibility knowing other professionals use his services. I would not hesitate to use Ray again in the future and recommend him to everyone."

"In case my photo doesn’t capture it, Dan is a very meticulous craftsman. It’s been several months since the installation and everything is working perfectly. Dan’s skill and artistry may speak for themselves, but there are a lot of other reasons I appreciate working with him. While this job was by no means inexpensive, Dan’s bid was significantly lower than the other contractors I considered, and those bids were for inferior equipment (Navien) whereas Dan installed Lochinvar combination boilers. Although Dan tends to be busy, he was able to work around a scheduling disaster caused by Mass Save and another contractor, and as a direct result of that flexibility we did not have to freeze in the house this fall. Another great thing about working with Dan, that I have yet to experience with any other contractor, is that he showed up every morning he said he’d be here, finished the project exactly when he said he would, and stayed on budget. Dan is also very pleasant to work with and so are his collaborators, assistants and subcontractors. It’s hard to believe I just found Dan by accident because he was the only plumber who didn’t try to gouge me for an emergency heating repair in 2022. I can’t recommend him enough."

Gas Leak Repair questions, answered by experts

Local codes often mandate specific fittings, permits, and vent considerations for permitted function and safety, which are enforced by professionals.

Yes, professional services typically include venting, gas line installation, and necessary permits.

Element, gas features, and complexity, including venting and connections, are typically higher due to safety and expertise factors.

Yes, professional installations typically include safe gas and plumbing connections.

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.
