What our gas leak repair includes
Every gas leak repair job is different, but here's what you can expect when you hire us. We'll tell you upfront if your job needs something beyond this scope.
Work order
Gas Leak Repair- Full system pressure test: We isolate your gas line, pressurize it with inert gas, and monitor the pressure gauge for 30 minutes. This confirms the leak is fixed and no others exist before we relight your appliances.
- Leak detection and location: Using a combustible gas detector and leak detection camera, we pinpoint the exact source - whether it's a fitting, a valve, or a section of pipe behind a wall or under a slab.
- Repair or pipe replacement: We cut out the damaged section and replace it with new copper pipe, PEX tubing, or CSST. We use brand-name fittings from SharkBite and Uponor and solder with a torch where code requires.
- Appliance relight and check: After the repair, we relight pilot lights on your water heater, furnace, and stove. We check that each appliance fires correctly and that no gas is escaping at the connection points.
- Written report and photos: You get a written summary of what we found, what we repaired, and the pressure test results. We also take before-and-after photos so you have a record for your insurance or home sale.

gas leak repair Lancaster PA: what it involves
A gas leak is not a wait-and-see problem. It is a safety issue that gets worse with time. Fixing it properly the first time is the only sensible choice.
It is not a DIY job. A single spark near a leaking fitting can ignite. Our technicians use a leak detection camera, pressure gauge, and combustible gas detector to pinpoint the source - whether it's a cracked pipe fitting, a failed valve, or a corroded section of copper pipe. We shut off the gas, repair or replace the damaged section, and pressure-test the entire line before turning the gas back on.
In Lancaster County, gas leaks often show up after seasonal temperature swings. Frozen pipes in January can crack a joint; summer ground movement can shear a buried line. Older homes in Downtown Lancaster and Millersville frequently have original black iron piping that's past its service life.

Our gas leak repair process
From the moment you call to the final pressure test, here's exactly what happens when you hire us for gas leak repair in Lancaster PA.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
A flexible inspection camera that lets us see inside walls, under slabs, and behind appliances without tearing everything apart. It shows us the leak source on a monitor.
We pressurize the gas line with inert gas and watch the gauge for drops. A steady reading confirms the repair is tight and no other leaks exist.
Clean, square cuts and press fittings for copper and PEX. These tools let us make code-compliant repairs quickly without open flames in tight spaces.
For copper pipe repairs, we solder with a torch where code requires. SharkBite push-to-connect fittings are used for quick, reliable joins in accessible areas.

How gas leak repair works in Lancaster
Lancaster County has a mix of housing stock that affects how gas leaks happen and how we repair them. In Downtown Lancaster and older neighborhoods like Southside and West End, many homes still have original black iron gas piping installed before 1950.
Downtown Lancaster
Century-old rowhomes with original gas piping. We see more joint leaks and corroded fittings here than anywhere else in the county.
Millersville
Newer construction with CSST gas lines. Rodent damage and shifting soil are common causes of leaks in this area.
Cedar Heights
Post-war homes with copper gas lines that are now reaching the end of their service life. We replace sections rather than patch them.

PhotoCracked fitting behind a kitchen stove
Before: A homeowner in Downtown Lancaster smelled gas every time she used her stove. The leak was a cracked brass fitting on the gas line behind the wall. She had been living with the odor for two weeks, afraid to call because she thought it would be expensive.
After: We replaced the fitting, pressure-tested the line at 10 PSI for 30 minutes, and relit the stove. She said she wished she had called sooner.
Buried gas line leak in Millersville
Before: A Millersville homeowner noticed dead grass in a stripe across his yard and a faint gas smell near the meter. The leak was in a buried copper line that had corroded through. His gas bill had been creeping up for months.
After: We located the leak with a soil probe and leak detection camera, excavated a 4-foot section, and replaced the copper with PEX. The pressure test held steady.
Commercial kitchen leak in Northside
Before: A restaurant owner in Northside smelled gas during dinner prep. The leak was at a union fitting on the main gas line feeding the kitchen. He had to shut down service for the evening and was worried about losing a weekend of business.
After: We arrived within an hour, isolated the line, and replaced the union fitting. We pressure-tested the commercial system and coordinated with the fire marshal for a same-night inspection. The restaurant reopened for lunch the next day.
Gas leak problems we solve in Lancaster
From faint odors to full-blown emergencies, these are the gas leak issues Lancaster homeowners call us about most.
Rotten egg smell near the meter or appliances
Mercaptan is added to natural gas so you can smell a leak. If you notice it, gas is escaping somewhere in your system.
Hissing sound from a gas line
A hissing sound means gas is escaping under pressure. It can fill a basement or crawlspace quickly.
Unexplained high gas bills
You pay for gas that never reaches your appliances, and the leak can worsen over time. We perform a full pressure test and leak detection scan.
Dead grass or wet spots above a buried gas line
Buried gas lines can corrode or shift with frost and soil movement. A leak underground can migrate into your home or a neighbor's.

What Lancaster customers say
I smelled gas near my stove on a Sunday night. Lancaster Plumbing Pros had a plumber at my door in 40 minutes. He found a cracked fitting behind the stove, replaced it, and pressure-tested the line. The price was exactly what he quoted. I can't recommend them enough.
Our gas bill spiked and we couldn't figure out why. Their technician used a leak detection camera and found a pinhole leak in the line running to our water heater. He repaired it the same day and showed us the pressure test results. Professional and thorough.
A gas leak in our kitchen could have shut us down for a week. Lancaster Plumbing Pros came out after hours, isolated the leak, and had us back open for lunch the next day. They knew the commercial code requirements and handled everything.
