Gas line work demands the highest level of expertise, licensing, and safety protocol — there is no margin for error with natural gas and propane. Plumbing HVAC Services New Hampshire employs licensed gas fitters who work exclusively within NH's regulatory framework for gas line installation and repair. We serve residential and commercial customers throughout New Hampshire for all gas line needs.
Gas Line Services We Provide in NH
Gas Line Installation in New Hampshire
New gas line installation is required whenever you're adding a gas appliance, converting from oil or electric to gas, extending service to an outdoor kitchen or fire pit, or connecting a whole-house generator. All gas line installation in New Hampshire requires permits and inspections by a state-licensed gas fitter — work we handle from permit application through final inspection.
We install both black iron pipe (the traditional material, still used for interior gas lines) and CSST (corrugated stainless steel tubing), which is approved for interior use in New Hampshire when properly bonded. Outdoor and underground runs use coated steel or PE gas pipe approved for burial.
Gas Leak Detection & Repair
Gas leaks are a serious safety emergency. If you suspect a gas leak — detected by smell (the odorant added to natural gas smells like rotten eggs), hearing a hissing sound near a gas line, or seeing dead vegetation above a buried gas line — leave the building immediately and call 911. Once the scene is declared safe, our licensed gas fitters can locate the leak precisely using electronic gas leak detectors and pressure testing, then repair or replace the affected pipe or fitting.
Propane Gas Line Services in NH
Many rural New Hampshire homes and businesses rely on propane because natural gas service is not available in their area. Propane lines serve the same appliances as natural gas but at different pressures and require different fittings and regulators. We're fully equipped for propane gas line work and coordinate with your propane supplier as needed.

Gas Line FAQs
Yes. New Hampshire requires a licensed gas fitter for any gas line installation or repair. This is not a DIY project — unlicensed gas work is illegal, voids homeowners insurance, and is genuinely dangerous. Always hire a licensed contractor.
The most common indicator is the smell of rotten eggs (the odorant added to natural gas and propane). You may also hear a hissing sound near gas lines or appliances, see bubbles in standing water near buried lines, or notice dead patches in your lawn above underground pipes. If you suspect a leak, leave immediately and call 911.
A simple appliance hookup or short gas line extension runs $150–$400. New full-home gas service or major extensions typically range $800–$3,000+ depending on run length, material, and complexity. We provide a written estimate before any work begins.
Yes. Running a permanent gas line to an outdoor grill, fire pit, or outdoor kitchen is a popular upgrade for NH homeowners. It requires permits and a licensed gas fitter but eliminates the hassle of propane tanks. Installation typically runs $400–$1,200 depending on distance from the gas meter and complexity.
Yes, when installed correctly. CSST (corrugated stainless steel tubing) is approved in NH but requires proper bonding to protect against lightning-induced arcing. We install CSST per NH code requirements including all required bonding connections.
