If you smell gas right now: Leave the house. From outside, call Atmos Energy at 866-322-8667 to shut off service at the meter (no charge). Then call us at 682-284-0966 to schedule leak detection and repair.
Texas Master Plumber License #M-17697. Serving Plano since 1990.
What to Do RIGHT NOW If You Smell Gas
- Leave immediately. Don’t turn on lights, don’t use a phone inside, don’t flip switches, don’t start vehicles in an attached garage. Any spark can ignite gas.
- From outside, call your gas utility. Atmos Energy emergency line: 866-322-8667. They will dispatch a technician and shut off service at the meter at no charge. This is the first call.
- Then call a licensed plumber. That’s us at 682-284-0966. Once Atmos has confirmed the shutoff, a licensed plumber locates the leak, pulls a permit, performs the required pressure test, makes the repair, and schedules the city inspection.
- Don’t try to find the leak yourself. The detection process requires a calibrated combustible gas detector and proper ventilation procedures.
Why Texas Requires a Licensed Plumber for All Gas Line Work
Texas Occupations Code Chapter 1301 requires that all gas line work — installation, repair, alteration, testing — be performed by a licensed plumber working under a Responsible Master Plumber. There is no homeowner exemption for gas.
NFPA 54 sets technical standards: gas line sizing based on BTU load, materials approved for residential use, pressure testing requirements, venting standards.
Local city codes in Plano, Frisco, McKinney, and Allen each have small variations we track. Every job gets a permit, a pressure test, and a final inspection by the city.
Gas Line Services We Provide
Gas Leak Detection: Combustible gas detector and pressure testing identify the leak location. Standard test is 2.5 PSI for residential, held for 15+ minutes.
Gas Line Repair: We pull the city permit, isolate the affected line, replace failed sections, pressure-test the repair, and schedule the city inspection. Atmos restores service after the green tag.
New Gas Line Installation: For new appliances (gas range, dryer, water heater conversion, outdoor kitchen, fire pit, pool heater). Sized based on total BTU load of all connected appliances.
Generator Gas Line Hookup: Whole-home standby generators require dedicated gas line capacity, typically 18,000–35,000 BTU/hr at the generator.
Tankless Water Heater Gas Line Upgrades: A tank water heater uses about 40,000 BTU. A whole-home tankless can need 180,000–199,000 BTU — 4–5x more. The existing line frequently can’t deliver it.
