The Nashua angle on gas work
A Nashua pro's first questions are about the appliances and the run. Older downtown stock retains original galvanized and cast-iron plumbing. Add hard freezes: New Hampshire winters burst exposed pipes and freeze hose bibs — winterizing hose bibs and insulating exposed lines prevents the most common cold-weather calls., and exterior or crawl-space runs need the pro's judgment on protection and routing.
From French Hill to the North End, Nashua homes add gas appliances the same way: one project at a time. Older downtown stock retains original galvanized and cast-iron plumbing. Each addition is a chance to verify the line can carry the load.

When to call about a gas line
Gas issues divide into two categories: smell gas now (leave, call the utility), and everything else below — which still needs a qualified pro promptly.
- A rotten-egg or sulfur smell near gas appliances or lines.
- A hissing sound near a gas connection or meter.
- Dead vegetation in a line above a buried gas pipe outdoors.
- A gas appliance that will not stay lit or burns with a yellow flame.
- Higher-than-normal gas bills with no change in usage.
Install, extend, repair — what's covered
Every joint tested, every line sized, every permit handled. That is the scope of proper gas work.
- Assessment of the existing gas piping: material, sizing, and condition.
- New gas line runs for appliances, outdoor kitchens, generators, and fire features.
- Repair or replacement of corroded, undersized, or damaged sections.
- Proper sizing calculations so every appliance gets the gas it needs.
- Pressure testing of all work before anything is put into service.
- Coordination on permits and inspections where the locality requires them.
Safety first: what to do
Memorize the smell-of-gas drill before you ever need it. Then handle the non-emergency steps.
Safe to do now
- Know where your gas meter shutoff is and how to turn it with a wrench.
- Keep the area around the gas meter clear and accessible.
- Install a carbon monoxide detector near gas appliances.
- Note the location of buried gas lines before any digging — call 811 first.
Stop — call a pro
- Never attempt gas line work yourself — no fittings, no extensions, no exceptions.
- Do not use open flame to check for leaks.
- Do not ignore a gas smell hoping it dissipates — leave and call for help.
- Do not bury or conceal gas connections where they cannot be inspected.
How gas line work unfolds
From your appliance plans to a tested, inspected line — how it progresses.
Safety first: if you smell gas, leave the house and call the gas utility or 911 — do not operate switches or phones inside.
Leak detection: the pro isolates sections and pressure-tests to pinpoint the leak.
Repair or new run: damaged sections get replaced; new appliance runs get sized, routed, and permitted.
Test and verify: every joint is pressure-tested and inspected before gas service is restored.
What drives the price
Material, distance, trenching versus interior runs, and permit requirements shape the number. Know them.
- New installation versus leak repair.
- Line length and routing — through walls, attic, or underground.
- Pipe material — black iron, CSST, or copper depending on code and application.
- Permits and inspections required by the city.
- Number of appliances on the run and total BTU load sizing.
