Shield Plumbing installs and repairs gas lines for water heaters, ranges, dryers, grills and fireplaces in homes across Kannapolis, Concord, Salisbury and Mooresville. Every line is pressure tested before it goes into service.
If you smell gas, leave the house now and call your gas company from outside. For new gas lines, such as a range, dryer, grill or tankless heater, we size the pipe, run it, and pressure test it. You get an estimate before any work starts.
Some gas line needs are planned upgrades. Others are warning signs. Here is what to look for.

Gas lines carry natural gas or propane from your meter or tank to the appliances that burn it. When you add an appliance, the pipe must be sized for the total load on the system. An undersized line starves appliances. A poor joint can leak. Both are why gas work belongs with a licensed plumber.
| Job | Typical time |
|---|---|
| Appliance hookup on existing line | 1 to 2 hoursConnecting a range or dryer where a valve exists. |
| New line to one appliance | Half a dayDepends on the distance and route from the main line. |
| Outdoor grill or fire pit line | Half to a full dayIncludes routing outside and a shut-off valve. |
| Gas line upsizing for tankless | 1 full dayReplacing an undersized run from the meter. |
Gas line cost depends on how far the line runs, what it passes through and how much gas the appliance needs. A short hookup is a small job. A new run to the backyard is larger. You get an estimate before any work starts, including any permit the job needs.
| Factor | How it affects the price |
|---|---|
| Length of the run | Longer runs from the main line take more pipe and labor. |
| Access | Open crawl spaces are simpler than finished walls or ceilings. |
| Pipe size | High-demand appliances like tankless heaters need larger pipe. |
| Indoor or outdoor | Outdoor lines need weather-rated routing and sometimes trenching. |
| Upsizing the system | Adding a big appliance may mean resizing part of the existing line. |
| Permit and inspection | Gas work usually needs a permit and a county inspection. |
We add up every gas appliance so the pipe is sized to feed them all.
We map the shortest safe path through the crawl space, attic or wall to the appliance.
We install the pipe, add a shut-off at the appliance and seal every joint.
We pressure test the line for leaks, then light the appliance and check the flame.

Many older homes in Kannapolis and Salisbury started with electric appliances or a small gas water heater. Adding a gas range or a tankless heater often means the original line is too small. Old gas pipe in a crawl space can also show rust after decades in damp air.
Newer homes in Mooresville and Harrisburg often have gas already, but owners want lines for outdoor kitchens, fire pits and grills. Rural homes in Landis and Rockwell may run on propane from a yard tank. We work on the house side of the system and tell you when the supplier needs to be involved.
Leave the house right away. Do not flip switches, light anything or use your phone inside. Once outside and away from the house, call your gas company or 911. After the gas company makes it safe, a licensed plumber can repair the leaking line or fitting.
Yes, gas line work should be done by a licensed professional. The pipe must be sized for all your gas appliances, joints must be sealed correctly, and the line must be pressure tested. Most gas work also needs a permit and inspection from your county.
Yes. A fixed gas line ends the need to swap propane tanks. The line is run from your existing gas system, routed safely outside, and finished with a shut-off valve. A plumber checks that your system has enough capacity for the added load first.
Signs include a rotten egg smell, a hissing sound near a pipe, or dead grass along a buried line. If you notice any of these, leave the house and call your gas company from outside. Do not try to find the leak yourself. A plumber repairs the line once the gas company makes it safe.
Often it cannot without changes. Tankless units use much more gas while running than a tank water heater. Many lines were sized for a tank, a furnace and a stove. We measure your line and total your appliances, then tell you if any section needs upsizing.
Most new gas line work needs a permit and an inspection. The rules can vary, so check with your county building inspections office for your address. When we give you an estimate, we tell you whether we expect a permit and how inspection affects the schedule.
Common options are black steel pipe and flexible yellow-coated tubing called CSST. Each has its own rules for routing and bonding, which means connecting it to the home's grounding system. We choose the right type for your route and install it to code.
Yes. If your range is moving, the gas line and its shut-off valve need to move too. We plan the new route with you, run the pipe before the cabinets go in when possible, and pressure test it. Doing it early keeps the remodel on schedule.
We work on the gas piping inside and around the home, including propane piping from the tank regulator to your appliances. The propane tank, regulator and supply belong to your propane company. If the issue is on their side, we tell you so you can call them.
