If You Smell Gas, Do This First
If you smell gas, leave the building immediately. Do not operate any electrical switches, appliances, or open flames. Do not use your phone until you are outside and away from the structure. Call 911 and PG&E from a safe distance. Once the immediate safety situation is handled, call Knights to locate and repair the gas leakage.
Why Modesto Gas Lines Fail
Modesto’s older neighborhoods in Sunnyside, Bret Harte, and the College Area have homes with gas lines that were installed 50 to 70 years ago. Stanislaus County’s clay-heavy soils shift significantly with seasonal moisture changes, placing ongoing mechanical stress on underground and in-wall gas line runs. Add decades of appliance replacements, each one a potential connection point that may or may not have been installed correctly, and the picture becomes clear: older Modesto homes carry a real gas line risk that most homeowners never think about until something signals a problem.
Common gas line failure points in Modesto include:
- Aging black iron lines corroded at fittings and joints
- Flexible appliance connectors. The corrugated connectors behind ranges, dryers, and water heaters have a finite service life and are a frequent source of small leaks
- Soil movement damage when underground runs shift with seasonal ground movement
- Previous uncertified work where connections were made without permits or pressure testing, and were never properly inspected
Gas Leak Detection and Repair
Professional gas detection equipment locates leaks precisely, including micro-leaks too small to smell clearly but significant enough to create ongoing risk. You get a fixed price before the repair begins. All plumbing work is licensed, permitted, and inspected. We don’t leave a gas repair without confirming the system is safe and up to code.
