A gas leak is not a plumbing inconvenience — it is a life-safety emergency. Natural gas (Atmos Energy) and propane are both odorized with mercaptan to smell like rotten eggs specifically so leaks can be detected before ignition risk. If you smell that odor anywhere in the home, garage, or near an appliance, leave the building immediately. Do not switch lights, unplug appliances, or use the garage door opener. Call from a safe distance.
Crystal Falls Plumbing runs 24/7 licensed gas leak response across Leander and Williamson County. Our licensed gas plumbers arrive with combustible-gas indicators (CGI), soap-bubble test kits, and every fitting needed to isolate a leak, pressure-test the line, and complete a code-compliant repair with permit and inspection through the City of Leander or Williamson County.
Signs of a Gas Leak
The odor is the first sign, but there are others — dead vegetation, hissing, high bills, and unexplained illness in the home.
- Rotten egg or sulfur smell inside or near appliances
- Hissing sound at a gas line, meter, or appliance
- Dead grass or plants in a straight line in the yard
- Higher-than-normal Atmos Energy bill without usage change
- Unexplained nausea, headaches, or dizziness at home
- Yellow (not blue) burner flames on a gas stove or water heater
How We Handle a Gas Leak Call
- 1. Isolate & Ventilate
On arrival we shut the gas at the meter, ventilate the affected area, and confirm the leak with a combustible-gas indicator.
- 2. Locate the Leak
We pinpoint the exact leak with soap-bubble testing on suspect fittings, appliances, and the CSST run.
- 3. Repair to Code
The failed segment is replaced with new black iron or approved CSST, properly bonded to the electrical ground, and re-tested.
- 4. Pressure Test & Restore Service
The repaired line is pressure-tested at 3 PSI for the minimum time required by code, documented with photos, and gas is restored.
What a Gas Leak Call Actually Includes
- Phone-guided evacuation — we tell you to leave the house first and call from outside; no light switches, no fans, no touching anything electrical
- 24/7 dispatch of a licensed Master Plumber with active natural-gas and LP endorsements
- Combustible-gas detector sweep of the meter, service riser, buried run, appliance stubs, and every joint
- Immediate isolation at the meter or affected shut-off; every impacted line pressure-tested before restore
- Repair with matching material (yellow CSST or black iron per code) with bonding to current NEC and a permit pulled where required
- Written cause-and-scope report and closed inspection record for insurance and peace of mind

- 2Repair material (black iron, CSST)
- 3Whether the meter set requires Atmos Energy involvement

Serving Leander & Williamson County
In newer Leander construction — Travisso, Bryson, Crystal Falls, Mason Hills — yellow CSST tubing is used almost exclusively for gas distribution inside the walls. CSST requires proper bonding to the electrical grounding electrode to prevent lightning-induced pinhole failures. We routinely find missing or improperly installed bonding on 2- to 8-year-old Leander homes; if you own one, get it inspected.
