Gas lines
Gas line work that gets tested in front of the inspector
Gas is the one part of home services where a shortcut can kill someone. Every line we install or repair is pressure tested, permitted and inspected, and the test results are documented in writing.
Smell gas right now? Leave the house, do not flip switches or use a phone inside, and call 911 or Southwest Gas from outside. We handle gas line repair and installation, but an active leak is a utility and fire department emergency first.
Straight answer
What does gas line work cost in Phoenix?
A new line for an outdoor kitchen, pool heater, fire pit or garage heater typically costs $800 to $3,500 depending on length, route and whether a concrete surface has to be crossed. Repairs and appliance connections generally run $250 to $900. Pressure testing, permits and inspection are included in our written pricing.
Gas piping is permitted work in every Valley city we serve, and the inspection protects you. If a contractor offers to run a gas line without a permit, the answer for your insurance and resale purposes is no.
What our gas line service includes
- Pressure test and leak search on existing lines using a calibrated gauge and soap solution at every joint and valve.
- New line installation in black steel or corrugated stainless, sized correctly for the appliance's BTU demand.
- Appliance connections for ranges, dryers, water heaters, furnaces, fire pits, pool heaters and generators.
- Line replacement where coatings have failed, sections are corroded, or an old line cannot safely serve a new load.
- Permits and inspection pulled in your city, with the test witnessed and documentation emailed to you.
- Bonding and grounding checks on corrugated stainless lines, which code requires and inspectors verify.
Safety signs
Signs of a gas problem that needs attention
- A rotten-egg smell near an appliance, meter or exterior line.
- A hissing sound at a valve, fitting or meter connection.
- Dead grass or a persistent wet patch along a buried gas line route.
- Burners that light unevenly or a pilot that will not stay lit.
- A gas bill that jumps with no change in use.
- Any corrosion, physical damage or exposed pipe coating in the yard.
Carbon monoxide is a separate hazard with no smell at all, so a working CO alarm near sleeping areas belongs in every home with gas appliances.

Gas line questions
Leave the house. Do not flip switches, make calls inside or start a car in the garage. Call 911 and the gas utility from outside. An active leak is handled by the utility and fire department before any plumbing contractor gets involved.

Yes. New gas piping, replacements and appliance connections require a permit and pressure inspection in Phoenix, Scottsdale and the surrounding cities. We pull the permit, test in front of the inspector and give you the paperwork.
Black steel and corrugated stainless lines commonly last 25 years or more when properly installed and protected. Failures usually trace back to damaged coatings, movement, bad connections or corroded exterior sections rather than the pipe material.
