"I had Rob install a tankless hot water heater, whole house water filter, and run a new gas line for my gas stove conversion. He was very professional and and was quick to set an appointment. The whole job took a single day and he even removed and disposed of the old outdated appliances. Quality work at reasonable prices! Would highly recommend."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Scheduling was challenging. On the first attempt, the service guy never arrived. When I called, the scheduler said there was some computer error, apologized, and rescheduled. On the second attempt, the guy came and did the service, then recommended having the expansion tank replaced. I was supposed to get a call to schedule the follow-up service, but never did. I called a few times and left a message, eventually getting a callback from someone who was able to schedule the service. Once again, the first attempt was a flop. They sent out a heating technician, not a plumber, to replace the expansion tank, which he was not certified to do...and he arrived late. On the second attempt, the plumber arrived on-time. He was very professional, efficient, and did great quality work. He made a recommendation for some other plumbing work after I asked him about an issue we had been having. He told me to call the company to schedule the work. Once again, I struggled to even get the service scheduled. This time, I gave up after 3 or 4 tries. I'll be contacting another plumber to get the work done at some point."

FAQs for gas piping projects in Portsmouth, NH

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
