"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

I had planned to work a half day from home but ended up working the whole day from home. (I am fortunate that my employer is flexible.) Other than that, everything was great. They were professional, friendly, did good work, put down a tarp to protect my laminate flooring, and cleaned up after themselves. I would recommend them to others and would use them again."

"Leave your worries to us" We are a company that believes in taking care of our customers. Our customers are our priority. We stand behind our workmanship and parts.

"We purchased our house back in late April 2021. During the inspection process, we found a leak above the garage. Southern New Hampshire Plumbing and Heating was hired to fix the leak. Eric from Southern New Hampshire Plumbing and Heating came out on April 23rd 2021 to fix the leak above our garage. Turns out there was a water pipe that was punctured by contractors from when they nailed in baseboards in the laundry room above our garage. Fixing this required cutting a hole in the wall to get to the punctured pipe. When Eric fixed the pipe, we believed the problem was fixed, however now, 3 months later, we are noticing there is leaking again in the exact same spot. We called the company, as they claim they warranty their work for 12 months, and they are refusing to fix their work because “the property was technically sold after the work was done”. Even though the work was done FOR THE SALE, as PART OF THE TERMS OF THE PURCHASE AND SALE ON THE HOUSE. PLEASE take caution before hiring this company. Clearly their work doesn’t hold up, and they don’t honor their work like they claim to."

Gas Leak Repair questions, answered by experts

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

The cost to move a gas line is around $500 on average or $20 per linear foot . A pro will carefully disconnect the existing gas line and reroute it to its new path. This may involve excavation if the line is underground or drywall work to repair your walls and ceilings. The project will finish with a pressure test to check for leaks and turning the gas line back on.

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.
