Service Overview

About Gas Line Services

Natural gas and propane power some of the most important appliances in your home — ranges, furnaces, water heaters, clothes dryers, fireplaces, outdoor grills, and generators. When your gas system works well, it provides efficient, reliable energy. When it doesn't, the consequences range from cold showers and cold houses to genuine fire and carbon monoxide hazards. Gas line work requires licensed plumbers or gas fitters — this is not a DIY endeavor.

Gas line installation services cover new gas appliance connections (adding a gas line for a new stove or dryer), running natural gas lines to outdoor kitchens or fire pits, extending service for home additions, and installing gas meter and pressure regulators. New gas line installation costs $15–$25 per linear foot for materials and labor, with most single-appliance connections running $300–$800 total. Running a line across a yard to an outdoor kitchen can cost $500–$2,000+ depending on distance and obstacles.

Gas line repair addresses leaking connections, damaged or corroded sections of black steel or CSST (flexible corrugated stainless steel tubing) pipe, and failed shutoff valves. All repairs require pressure testing after completion to verify the line is sealed. Gas line repair costs $200–$800 for typical repairs; emergency leak repair with same-day response runs higher.

If you smell gas, the response protocol is immediate: stop using all electrical devices (including light switches), open windows, leave the building, and call both your gas utility's emergency line (on your bill) and 911 from outside the home. Your gas utility will turn off service at the meter; a licensed gas plumber will then locate and repair the leak before gas can be restored. Never attempt to locate or repair a gas leak yourself.

Warning Signs

Signs You Need Professional Gas Line Services

1
Sulfur or rotten egg smell near gas appliances

Natural gas is odorless; utility companies add mercaptan (a sulfur compound) specifically so you can smell leaks. Any gas smell requires immediate evacuation and emergency response — no exceptions.

2
Hissing sound from gas lines or connections

An audible hiss from a gas pipe, connection, or appliance indicates gas escaping under pressure. Evacuate immediately and call for emergency service.

3
Dead plants or vegetation over buried gas lines

A leaking buried gas line displaces oxygen in the soil, killing plants or grass above it in a strip-like pattern — often one of the first external signs of an underground gas leak.

4
Higher-than-usual gas bills without explanation

A small, slow gas leak may not smell but will register on your meter as unexplained consumption increase. Compare your bills month-over-month and year-over-year.

5
Gas appliance won't light or has weak flame

A blocked burner, bad igniter, or gas supply issue can prevent appliances from lighting or cause weak, yellow, or orange flames instead of the normal blue.

6
Installing new gas appliances

Any time you add a gas appliance — range, dryer, generator, outdoor grill — a licensed gas plumber must run and connect the supply line and verify proper pressure.

Common Questions

Frequently Asked Questions About Gas Line Services

Immediately: 1) Stop using any electrical devices — don't even flip a light switch. 2) Open windows if quick to do. 3) Leave the building immediately. 4) Call 911 and your gas utility from outside or a neighbor's home. 5) Do not re-enter until cleared by authorities. 6) Call a licensed gas plumber after the utility has confirmed the leak and shut off service.
In most states, licensed master plumbers are also licensed to perform gas line work. Some states require a separate gas fitter license. Always confirm your plumber is licensed for gas work in your state — ask to see their license number and verify it with the state licensing board.
Running a gas line for a new kitchen range typically costs $200–$600 depending on the distance from the nearest gas supply and whether walls need to be opened. If you're converting from electric to gas, add the cost of a new gas shutoff valve and appliance connector. Outdoor kitchens cost $500–$2,000+ depending on distance from the house.
Modern residential gas lines use black steel pipe (most common for main lines), CSST (corrugated stainless steel tubing — flexible, faster to install), copper (in some older homes), or polyethylene (underground service lines only). Each material has specific installation requirements. CSST requires bonding/grounding to prevent lightning damage.
The National Fire Protection Association recommends having all gas appliances, connections, and visible piping inspected every year as part of annual HVAC maintenance. Underground gas lines can be inspected via pressure test. If your home is over 25 years old, a full gas line inspection is worth scheduling proactively.
Your gas utility turns service back on at the meter after verifying the system is safe. If gas was shut off for a leak, a licensed plumber must complete repairs and provide documentation before the utility will restore service. The utility may require a pressure test to be present for. This process typically takes 1–3 days after the repair is complete.
