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."

Gas Leak Repair questions, answered by experts

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

Installing a gas line can be extremely time-consuming and dangerous, so you will want to hire a seasoned professional. Perform a thorough search ahead of time to find a reputable and reliable plumber. Pay special attention to licensing and insurance as you go about choosing the best contractor for your needs.

Modern gas fireplaces are relatively efficient and don't burn excessive amounts of gas, especially compared to older models. A gas fireplace might use between 10,000 to 40,000 BTUs per hour; the total amount of gas used depends on the fireplace's size, heat output, and how often it's in use. To help keep your running costs down, consider using a thermostat and turning off the fireplace when not needed to minimize gas consumption

In most cases, a gas stove should be installed by a licensed plumber. Connecting gas appliances carries many risks, chief among them a fatal gas leak. If your home is already set up with the proper gas hookups, you may be able to DIY the installation (or save money by hiring a local handyperson or basic appliance installer near you rather than a plumber). If you’re ever in doubt, however, we recommend going with a professional master plumber.

If your existing gas line requires a simple fix or a small replacement and it's easy to access, you can expect it to take one or two hours. A more complex project like fixing an underground gas line can take several days to complete. Consult a gas plumber near you with the specifics of your project to receive an accurate estimate of the price and time commitment.
