Gas line repair in Aurora, CO
A gas leak is the one plumbing problem where you get out first and ask questions later. Once the utility or fire department has made the house safe, we find the leak on your side of the meter, repair it and pressure test the line.

Brands we work on every week
If you smell gas, leave the house now, then call 911 or Xcel Energy from outside. Do not flip switches or start a car in an attached garage. After the utility makes it safe, we locate the leak on your side of the meter, repair the pipe or fitting, and pressure test the system before gas is restored.
Warning signs
What tells you a gas line may be leaking?
A rotten egg or sulfur smell
Utilities add a sulfur odor to natural gas so leaks are easy to notice. If you smell it strongly anywhere in the house, get everyone out first and call from a safe distance.
Hissing near a pipe or appliance
A steady hiss at a fitting, valve or appliance connector can mean gas is escaping under pressure. Do not try to tighten anything yourself. Leave the house and make the call outside.
Dead grass in a straight line
A buried gas line leaking into the soil can kill grass or plants along its path. A brown strip running from the meter toward a grill, fire pit or detached garage is a warning sign.
Bubbles in puddles or wet soil
Gas escaping from a buried line can bubble up through standing water, mud or snowmelt near the pipe route. It looks odd, and it deserves a call to the gas utility right away.
A gas bill that jumps for no reason
A small, steady leak may not smell strong but can still show up as higher usage. A bill that climbs with no change in your habits or the weather is worth a pressure test.
Rusty pipe or a crushed connector
Black iron that is flaking at the threads, or an old flexible connector kinked behind a range or dryer, is a leak waiting to happen even if you smell nothing yet.
Step by step
From the first phone call to gas back on
- 01
Get out and call for help
If you smell gas, leave the house and call 911 or Xcel Energy from outside. Call us once the responders or the utility have made the home safe.
- 02
We confirm the gas is off
We verify the supply is shut at the meter or appliance valve, and we ventilate any rooms that still hold a smell before work begins.
- 03
We test and locate the leak
A pressure test confirms the leak, then branch by branch testing and electronic detection pinpoint the joint, connector or pipe section that failed.
- 04
We repair the faulty piping
You get a price before work starts. We replace the damaged section, connector or fitting with materials suited to the location and the gas load.
- 05
We pressure test and relight
The repaired system must hold pressure before gas is restored. Then we relight pilots and check every appliance burner served by that line.
Your safety comes before any repair
Natural gas leaks are handled by emergency responders and the gas utility first. They shut off the supply, ventilate and decide whether the house is safe to enter. In most of the Aurora area that utility is Xcel Energy. Our work starts once the immediate danger is controlled and the problem has been traced to piping on the customer's side of the meter.
That split matters. The utility owns and maintains the meter and the service line feeding it. Everything downstream, including the pipe through your walls, the branches to each appliance and any buried lines to a grill or garage, belongs to the homeowner. Repairing that house side piping, properly and safely, is exactly the work we do.

Finding the exact spot where gas is escaping
We isolate the system and pressure test it to confirm a leak exists, then narrow it down section by section. Common culprits are threaded joints that have loosened over decades, old uncoated brass connectors behind appliances, unions near the water heater and furnace, and corroded pipe where it passes through a damp wall or crawlspace.
We use electronic gas detectors and leak detection solution on every joint we can reach. When a leak sits inside a wall or underground, we test each branch separately so only the faulty run gets opened up. That approach keeps drywall cuts and digging to the smallest area possible, which saves you repair costs afterward.
Repairing, retesting and restoring gas service
Depending on what we find, the fix might be a new appliance connector, a remade threaded joint, a replaced section of black iron, or a new run of coated flexible gas line. Buried yard lines that have corroded are usually replaced rather than patched, since one rusted spot is rarely the only weak point along that pipe.
After the repair, the system is pressure tested and must hold steady before gas is turned back on. Then we purge air, relight pilots and check each appliance for proper burner operation. If the utility shut off or locked the meter, it typically restores service once the repaired piping has passed its test.
Aurora notes
Gas piping problems we see across Aurora
Older homes in Original Aurora and the central part of the city often still carry their original black iron gas pipe. Decades of temperature swings, settling and basement moisture can loosen threaded joints or rust pipe where it runs along a foundation wall. Front Range expansive clay adds another stress, because soil that swells when wet and shrinks when dry can strain buried lines and the spot where pipe enters the house.
Altitude plays a part too. Aurora sits at about 5,400 feet, so gas appliances need high-altitude setup for clean combustion and proper venting. When we repair a line serving a water heater, furnace or range, we check that the appliance is burning correctly before we leave. Gas piping work usually requires a permit and inspection in Aurora and nearby cities, and we pull the permit when the repair calls for one.
Pricing
How much does gas line repair cost in Aurora?
TYPICAL AURORA PRICE RANGES
| Gas leak detection and pressure test | $175 to $345 |
|---|---|
| Appliance flexible connector replacement | $165 to $295 |
| Threaded joint or gas valve repair on interior pipe | $245 to $565 |
| Interior gas pipe section replacement | $485 to $1,185 |
| Buried yard gas line repair or replacement | $945 to $2,875 |
These are typical Aurora ranges, not a quote. The real price depends on where the leak is and what we find once we test the piping.
- Where the leak isA leak at an exposed basement fitting is quick to reach. One inside a finished wall or under a deck takes more time to open up and close again.
- How much pipe failedA single bad joint costs far less than a run of corroded pipe that has to be replaced from one end to the other.
- Buried or exposedUnderground lines need a Colorado 811 locate before digging, then excavation, new pipe and backfill, which adds labor and time to the job.
- Appliances on the lineEvery appliance served by the repaired branch gets relit and checked. A house with several gas appliances takes longer to bring back online than one with a single water heater.

Questions
Gas Line Repair questions from Aurora homeowners
What should I do first if I smell gas in my Aurora home?
Get everyone out of the house without flipping light switches, using phones inside or starting a car in an attached garage. From outside and a safe distance, call 911 or Xcel Energy. Once they have made the home safe and traced the issue to your side of the meter, phone us for the repair.
Who is responsible for a gas leak, me or Xcel Energy?
In general, the utility handles the meter and the service line up to it. Piping on the house side of the meter, including the lines inside your walls and any buried runs to grills, heaters or outbuildings, is the owner's responsibility. That house side piping is what we repair and test.
Can a leaking gas flex connector be tightened instead of replaced?
We don't recommend it. Older connectors, especially uncoated brass ones, can crack inside the flare or along the corrugations, and tightening may make the leak worse. New coated connectors are inexpensive, so we replace a leaking one and test the joint every time.
How long does it take to get gas back on after a leak repair?
Simple repairs like a connector or a single joint are often finished and tested the same day. Larger pipe replacements can take longer, and if the work needs a city inspection or the utility has to restore a locked meter, the timing depends partly on their schedule.
Is a carbon monoxide alarm the same as a gas leak detector?
No. A carbon monoxide alarm senses a combustion byproduct, not natural gas itself. Explosive gas detectors are a separate device. Every home with gas appliances should have working CO alarms, and some owners add a natural gas detector near the furnace and water heater for extra warning.
