Gas is not something to troubleshoot yourself. If you smell gas, leave the property and call the utility or 911 first — then call us for licensed detection and repair. Our C-36 crews test, locate, and repair gas lines safely.
A suspected gas leak is a leave-now situation. Do not operate switches, test fittings, or search for the source indoors — leave the property and call the gas utility or 911 from a safe location. Once the immediate danger is handled, our licensed San Marcos technicians take over: we pressure-test the system, locate the leak, and repair or replace the affected line to code.
A California C-36 plumbing license covers gas piping, and gas work is exactly where licensing and permits matter most. We handle new gas lines for ranges, dryers, fire pits, pool heaters, and generators, plus repairs to corroded or damaged piping — always with testing and documentation, never a guess.
Signs of a gas problem
- A rotten-egg or sulfur odor near appliances or the meter
- A hissing sound near a gas line or connection
- Dead or discolored vegetation over a buried gas line
- A gas appliance that won’t stay lit or burns with an orange flame
- Higher-than-normal gas bills with no usage change
- Physical symptoms (dizziness, nausea) that ease when you leave the house
Our Process
- 1
Safety first
We confirm the property is safe to work on after the utility or 911 has addressed any active leak.
- 2
Pressure test
We test the gas system to determine whether it holds pressure and isolate the affected section.
- 3
Locate the leak
We pinpoint the failure at a fitting, corroded section, or damaged run.
- 4
Repair or replace to code
We repair or replace the line with proper materials and pull the required permit.
- 5
Re-test & document
A final pressure test and documentation confirm the system is safe before service is restored.

- Permit pulled, inspection scheduled, and a final pressure test before service is restored
Gas line installation done right
Adding a gas line for a range, dryer, outdoor kitchen, fire feature, pool heater, or standby generator isn’t just running pipe — it requires correct sizing for the appliance load, code-compliant materials and connections, a permit, and a pressure test. We plan the run, verify the system can carry the added demand, and document the work so it passes inspection and operates safely for years.
What Affects the Cost
Gas line cost in San Marcos depends on the length, access, and whether it’s a repair or new installation. Gas work requires testing and a permit, which we include and quote in writing.
- Repair of a leak vs. installing a new gas line
- Line length, routing, and access to the run
- Appliance load and required pipe sizing
- Pressure testing and permit/inspection
- Materials — black iron, CSST, or approved alternatives
