A suspected gas leak is an emergency. Do not attempt to locate or repair it yourself — leave the building, leave the gas off, and call a licensed plumber. Scott's H Plumbing provides gas line repair and gas leak response throughout York County for natural gas supply systems: detecting the leak source, repairing or replacing the damaged section, pressure-testing the line, and verifying safe operation of all gas appliances before we leave. 24-hour emergency gas line response is available.
24-Hr Emergency Dispatch · York, PAIf you smell gas or suspect a gas leak: do not turn any electrical switches on or off, do not use a phone inside the building, do not light any flame. Leave the building immediately, leave the door open as you go, and call York County 911 from outside. After emergency services respond and the gas is confirmed off, call Scott's H Plumbing at (717) 842-9770. We locate the leak source using pressure testing and gas detection equipment, repair or replace the damaged section of gas pipe, pressure-test the repaired line, and verify that all gas appliances are operating safely before gas service is restored. Gas line work requires a licensed plumber — this is not a repair to attempt without the proper licensing, tools, and pressure-testing equipment.
If you smell gas: leave the building and call 911. For non-emergency gas line service or after emergency services have responded, call (717) 842-9770 for gas line repair and pressure testing.
York County has a well-established natural gas distribution infrastructure, and a significant portion of the housing stock — particularly in York City and the older boroughs — runs on natural gas for space heating, water heating, and cooking. The vintage of the home largely determines what type of gas piping is inside the walls: homes built before the 1960s typically have black iron pipe threaded together at fittings, homes from the 1960s through the 1990s may have a mix of black iron and flexible corrugated stainless steel tubing (CSST), and newer construction and renovations use CSST throughout for its flexibility in routing.
Black iron pipe develops two failure modes with age: threaded joint connections can develop slow leaks as thread sealant (pipe dope) dries out and shrinks over decades, and sections can corrode where they pass through masonry or contact soil or moisture. CSST is not susceptible to the same corrosion issues, but it requires proper bonding to the grounding system to protect against lightning-induced arc damage — unbonded CSST has a small but real risk of perforation in a lightning strike event, and older CSST installations in York homes are sometimes found to be unbonded.
Beyond the supply lines themselves, the connections at each gas appliance — water heater, furnace, boiler, gas range, gas dryer — are a common location for slow leaks. Flexible gas connectors at appliances are rated for a finite service life and should be replaced when they show signs of corrosion, kinking, or damage, or when an appliance is moved or replaced.
Using electronic gas detection equipment and pressure testing, we locate the source of a gas leak in the supply system — at a threaded joint, a corroded section, a flexible connector, or a valve — and repair or replace the leaking component. The line is pressure-tested after repair before gas is restored.
After a repair, after a gas line is extended or modified, or when a gas smell cannot be traced to an obvious source, a pressure test is the definitive method for confirming whether the supply system is leak-free. We pressure-test to the standard required by Pennsylvania plumbing code and document the result.
The flexible corrugated connector between the gas shutoff and the appliance is subject to mechanical fatigue from appliance movement and chemical degradation over time. We replace corroded, kinked, or aged flexible connectors at water heaters, furnaces, ranges, boilers, and dryers.
Gas shutoff valves at appliance connections and branch lines can corrode or seize with age. A valve that cannot be operated freely is a safety hazard — it cannot be closed in an emergency. We replace seized or corroded shutoff valves and verify free operation before leaving.
Adding a gas range, outdoor grill connection, gas fireplace, generator hookup, or additional gas appliance requires extending the supply system with a properly sized branch line. We size the new branch for the appliance's BTU demand, route it safely, and pressure-test the extended system before connecting the appliance.
Older corrugated stainless steel tubing (CSST) installations in York homes are sometimes found to be unbonded or improperly bonded to the electrical grounding system. We inspect CSST bonding and install bonding connections where required by current code to protect against lightning-induced arc damage.
Do not turn any electrical switch on or off — a spark from a switch can ignite gas. Do not light any flame. Do not use a phone, flashlight, or any electrical device inside the building. Leave as quickly and calmly as possible.
Leave the building immediately and leave the door open as you exit to allow gas to disperse. Call 911 from outside or from a neighbor's home. Do not return to the building until emergency services confirm it is safe to do so and the gas supply has been shut off.
After emergency services have responded and the gas is confirmed off, call (717) 842-9770. We locate the leak source, repair the gas line, pressure-test the repaired system, and restore gas service to the appliances safely. Gas line repair requires a licensed plumber with the proper pressure-testing equipment.
Gas line repair and installation in Pennsylvania requires a licensed plumber. Scott's H Plumbing is licensed to perform gas line work in York County and carries the required insurance. This is not work to assign to an unlicensed contractor or to attempt without the proper tools and testing equipment.
Every gas line repair is followed by a pressure test of the system before gas service is restored. A repair that passes the pressure test is confirmed leak-free by measurement, not by smell or assumption.
Gas leaks do not happen on a schedule. We provide 24-hour emergency gas line response for York County calls after emergency services have responded and confirmed the building is safe to enter for repair.
After gas service is restored, each appliance connected to the system is checked for proper operation: pilot lights, burner function, ignition, and absence of odor at the appliance connection. We do not leave until everything connected to the repaired system is confirmed working safely.
Two decades of gas line service in York County means we have worked on every generation of gas piping found in local homes, from threaded black iron in pre-war housing to CSST systems in 1990s construction. We know what to look for and where.
"Gas company found a leak at the meter and shut us off. Called Scott's and they had someone here within hours. Found the joint that was leaking, repaired it, pressure tested, and had our heat back on the same day. Professional and fast."
"Smelled gas faintly near the water heater. Scott's came out, found the flexible connector was failing, replaced it, and checked every other appliance connection while they were there. Appreciated the thoroughness."
"Needed a gas line run to a new range in the kitchen. Clean work, properly sized, pressure tested, and they handled everything. No issues with the install at all."
Gas line repair cost depends on what failed and where. A flexible connector replacement at a single appliance is a short job. Locating and repairing a leak in a buried or concealed section of pipe requires more time and access work. A gas line extension for a new appliance depends on the run length and the complexity of the route.
We quote the repair after locating the leak source and assessing what is required to fix it properly. You receive a clear price before any repair work begins. Gas line work is not an area to make decisions on price alone — a pressure test that confirms the repair is leak-free is the standard we hold to, regardless of the job size.

Leave the building immediately without operating any electrical switches, using your phone, or creating any flame source. Leave the door open as you exit. Call 911 from outside or from a neighbor's home. Do not return until emergency services confirm the building is safe. After the gas is shut off by emergency responders, call (717) 842-9770 for gas line repair service.
No. Gas line repair in Pennsylvania requires a licensed plumber. Beyond the licensing requirement, gas work requires pressure-testing equipment to confirm that a repair is leak-free — smell alone is not a reliable test for a slow or small leak. An unlicensed repair that appears to hold but fails a pressure test is a life safety hazard. Call a licensed plumber for all gas line work.
Gas leak detection uses two methods in combination: electronic combustible gas detectors that identify gas-rich air at any accessible point along the line, and pressure testing, which pressurizes the system with air or nitrogen and monitors for pressure drop. A pressure drop confirms a leak exists; the gas detector locates it. Used together, these methods reliably find leaks that are too small or too concealed to locate by smell alone.
Flexible gas connectors at appliances are not rated for an indefinite service life. The general guidance is to replace them when they show any sign of corrosion, kinking, or physical damage, and to replace them automatically whenever an appliance is moved or replaced. A connector that has been in place for more than ten to fifteen years without inspection is worth having checked. Corroded connectors are one of the more common locations for slow residential gas leaks.
CSST (corrugated stainless steel tubing) is a flexible yellow-jacketed gas supply tubing that became common in residential construction from the late 1980s onward and is still widely used. It is flexible, easy to route, and corrosion-resistant. York homes built or renovated from roughly 1990 to present may have CSST. Older installations may require bonding to the electrical grounding system to protect against lightning-induced arc damage — we check bonding status as part of any gas line service call on a home with CSST.
Yes. Adding a gas range, outdoor natural gas grill connection, gas fireplace, gas generator connection, or any additional gas appliance requires extending the supply system with a properly sized branch line. We size the new line for the appliance's BTU input demand, route it safely, and pressure-test the extended system before connecting the appliance. Call (717) 842-9770 to discuss what is involved for your specific application.
