What Is Included in Gas Line Repair
Every gas line repair job includes the diagnosis, the repair itself, and the testing that proves the line is safe before we leave.

Work order
Gas Line Repair- Full Line Inspection: We walk the entire gas run from the meter to every appliance, checking joints with a combustible gas detector and soap solution. You get a photo record of anything suspect, even if it does not need repair today.
- Pressure Test: The suspect section is isolated and pressurized with a gauge. A 15-minute hold confirms whether there is a leak and exactly which segment is responsible. This is the step that separates a real gas problem from a pilot light issue.
- Repair or Section Replacement: Failed fittings are cut out and rebuilt with new brass fittings and pipe dope. Corroded or damaged pipe is replaced with copper pipe, PEX tubing, or approved CSST. Most repairs take two to four hours.
- Appliance Reconnection and Testing: After the repair, we reconnect and relight every appliance on the line, checking flame color, draft, and gas pressure at each connection. You get a walkthrough of what was fixed and what to watch for.
- Permit Coordination: When the scope requires a permit under the Uniform Plumbing Code or International Plumbing Code, we pull it and schedule the inspection. You do not have to chase the paperwork or the inspector.

Gas Line Repair charleston SC: What the Work Actually Involves
A gas line is not a place to guess. We test it, find the problem, fix it with the right material, and prove it holds before we leave. That is the whole job.
Gas line repair charleston SC is the diagnosis and correction of leaks, corrosion, blockages, and damaged fittings on the pipes that carry natural gas or propane into your home or business. It covers everything from a single weeping joint at a water heater connection to a full underground run that has been compromised by root intrusion or shifting soil. A technician isolates the affected section, pressure-tests it, and either repairs the fitting or replaces the pipe with copper pipe, PEX tubing, or CSST rated for gas service.
In charleston, gas lines take a beating. Salt air off the harbor corrodes brass fittings and steel nipples faster than inland, and the older homes around Harleston Village and Radcliffeborough often still have original black iron pipe that has been patched over the decades. Add storm surge, saturated soil, and temperature swings, and you get the kind of slow leak that shows up as a faint odor near the meter. That is when most people search for gas line repair near me charleston SC and want someone out the same day.

What to Expect From Start to Finish
Gas line work follows a set sequence. Here is exactly how a job runs, from the first phone call to the final pressure test.
Tools and Methods We Use on Gas Lines
Each method answers a different question. Together they leave very little to guess.
A camera on a flexible reel that lets us inspect underground and behind-wall gas runs without full excavation. It shows us cracks, corrosion, and root intrusion directly.
The gauge that proves whether a line holds. We pressurize the isolated section and watch for a drop over 15 minutes. No drop, no leak.
Clean, square cuts on copper pipe and CSST. A square cut is what lets a fitting seal properly, which is why we never use a hacksaw on gas pipe.
Used for copper pipe joints where sweating is the correct method. We keep the flame controlled and shield nearby framing so nothing else gets hot.

How Gas Line Repair Runs in Charleston
Gas line work in Charleston is shaped by three things: salt air, old houses, and soil that moves.
French Quarter
Historic homes with original gas runs and tight access. We use detection cameras to avoid opening finished walls wherever possible.
Harleston Village
A mix of renovated and original homes. Corroded fittings near water heaters are the most common call here.
West Ashley
Post-war homes with slab runs. Underground gas line repair is frequent because the original pipe has reached the end of its life.

PhotoCorroded Fitting Behind Water Heater
Before: A Harleston Village homeowner smelled gas near the water heater closet. The utility locked the meter. The original brass fitting had corroded through, and the steel nipple behind it was pitted from years of salt air exposure.
After: We cut out the failed fitting and nipple, rebuilt the connection with new brass and pipe dope, and pressure-tested the line. The gauge held for 30 minutes. The utility restored service the same afternoon, and the homeowner had hot water back by evening.
Root-Damaged Underground Gas Run
Before: A West Ashley home had a faint gas smell in the yard for weeks. Two other companies could not find it. Our leak detection camera traced the problem to a cracked section of underground pipe where a live oak root had pushed through the trench.
After: We excavated the damaged section, replaced 14 feet of pipe with new copper, and pressure-tested the full run. The sewer line in the same trench was also camera-checked and cleared. Total job took two days, including restoration.
Undersized Gas Line for Tankless Upgrade
Before: A Johns Island family replaced their tank water heater with a Navien tankless unit, but the existing half-inch gas line could not deliver enough BTU. The unit kept throwing error codes and cycling off during showers.
After: We calculated the BTU load, upsized the gas line from the meter to three-quarter inch, and ran new pipe to the tankless unit. After commissioning, the unit fired correctly and held temperature through back-to-back showers. The repair took one day.
Gas Problems We Fix in Charleston Homes
Most gas line calls fall into a handful of categories.
Gas smell near the meter or appliance
A persistent gas odor means an active leak. We pressure-test the line, isolate the leaking section, and repair the failed fitting or pipe.
Corroded brass fittings from salt air
Salt air off the harbor eats brass and steel faster than inland.
Root intrusion on underground gas runs
Lowcountry soil moves with every wet season, and roots follow the trench.
Gas appliance won't stay lit
A water heater or furnace that keeps going out is often starved by low gas pressure, not a failed appliance.

What Charleston Customers Say
Smelled gas near the meter on a Tuesday morning. Called at 8, had a tech at the house by 10:30. He pressure-tested the line, found a corroded fitting behind the water heater, and had it rebuilt with new brass by early afternoon. Price was exactly what he quoted on the phone. No surprises.
Our kitchen lost gas pressure during dinner service on a Friday. Charleston Harborline had a crew out within two hours, isolated a root-damaged section under the back patio, and had us cooking again by Saturday lunch. They coordinated with the utility so we did not have to make a single call.
We had a slow gas smell for weeks and two other companies could not find it. This team brought a detection camera, tested every joint, and traced it to a pinhole in the original black iron pipe under the slab. They replaced the run with PEX and re-tested. Six months later, no smell, no issues.
