If you smell gas, leave first
Gas is the one plumbing system where the first instruction is not about the repair. If you smell gas, leave the building, and from outside call the gas utility's emergency line and then us. Do not flip switches or light anything. A gas leak is not a fix-it-yourself situation and not one to wait on. Once safety is handled, the repair is a careful, tested process, not a quick patch.
Leaks turn up at fittings that have loosened, at connections to appliances, or in lines that have corroded. Finding the leak precisely, repairing the section, and then pressure-testing the line to confirm it holds before restoring service is the whole method. The test is not optional, because a gas line that has not been proven tight is not a line anyone should light.
New lines, done to code and tested
Adding a gas appliance, a range, a dryer, a heater, a generator or an outdoor grill, means running a new line sized to feed it, and the sizing matters: a line too small starves the appliance. This is permitted work under the building code, pressure-tested, and inspected before use. A gas tankless water heater or a gas boiler in particular draws high volume when it fires, so an existing line sometimes needs upsizing to feed a new one properly.
| Job | What it involves |
|---|---|
| Suspected leak | Locate, repair, pressure-test |
| New appliance line | Size, run, permit, test, inspect |
| Generator or grill line | Dedicated line, sized for load |
| Upsizing for a tankless | Larger line to feed peak demand |
Because gas work is permitted and inspected, it is a natural part of a larger plumbing installation or remodel where appliances are being added or moved. The one constant is the test: no gas line we run or repair goes back into service until it has held pressure and passed inspection.
Why the pressure test is non-negotiable
Every gas line we run or repair is proven with a pressure test before it is put back into service, and that step is not a formality to be skipped when a job runs long. The test isolates the line and confirms it holds pressure over time, which is the only way to be certain there is no slow leak at a fitting that would otherwise seep gas into the house undetected. A line that has not been tested and passed is not a line anyone should light, full stop. It is the single practice that makes gas work safe rather than a gamble, and it is why permitted, inspected gas work exists in the first place. We hold that line without exception.
Questions
Gas Line Installation & Repair: common questions
What should I do if I smell gas?
Leave the building first. Do not switch lights on or off, do not light anything, and do not look for the leak yourself. Once you are outside, call the gas utility's emergency line and then call us. A gas leak is a safety emergency, not a repair to wait on. After the immediate danger is handled, we locate and repair the leak and pressure-test the line before restoring service.
Do I need a permit to add a gas appliance line?
Yes. Running a new gas line for a range, dryer, heater, generator or grill is permitted work under the building code, and it is pressure-tested and inspected before use. That process is what confirms the line is sized correctly for the appliance and tight enough to be safe. We pull the permit, run and test the line, and handle the inspection.
Can my existing gas line feed a new tankless heater?
Not always. A gas tankless water heater draws a high volume of fuel when it fires, often more than a line sized for older appliances can deliver. Part of the job is confirming the existing line can feed the new unit at peak and upsizing it if it cannot. The same is true for high-output gas appliances generally.
