Professional Gas Line Repair & Leak Detection Services
What is gas line repair & leak detection and when do you need it?
Gas line repair and leak detection is safety work first and plumbing work second, and Avanté Plumbing is licensed to carry it out across Sonoma and Marin County under California CSLB licence #841938 (C-36 Plumbing). If you can smell gas right now, stop reading, leave the building, and call your gas utility or 911 from outside — do not use light switches, and do not use the contact form on this website. For non-emergency work, we test and repair gas lines, track down small leaks at fittings and unions, and run new lines for ranges, dryers, water heaters, fire pits and outdoor kitchens. Warning signs worth a call include a faint gas smell near an appliance, a hissing sound at a connection, pilot lights that will not stay lit, or dead patches of grass over a buried line. Every job is pressure tested before we sign it off.

Common questions
Gas Line Repair & Leak Detection FAQs
What qualifications do your plumbers hold?
All our plumbers are fully licensed, insured, and have years of experience. They are trained to handle gas line repairs with precision and safety in mind.
Will I need to leave my home during the repair?
In some cases, if the leak is significant, it may be safest to evacuate until repairs are made. Our team will guide you through the process and keep you informed every step of the way.
Do you offer any warranties on gas line repairs?
Yes, we stand behind our work. Our repairs come with a warranty to give you peace of mind knowing that we'll be there if you encounter any issues after the service.
What should I do if I smell gas?
Leave the building first. Do not switch anything on or off, including lights, and do not use a phone inside the building — then call 911 or your gas utility from outside. This is the one plumbing situation where the correct first step is evacuation rather than a service call. Once the utility has made it safe, the repair itself is licensed plumbing work.
Do I need a permit for gas line work?
Yes, whenever gas piping is installed, extended, altered or relocated. Permit Sonoma's fee schedule expressly includes gas piping systems, listing $8.26 for a system serving one to four outlets against the $327 minimum trade permit fee, and its records show permits for dedicated gas lines and gas house line extensions. Those are county fees rather than ours.
Why would a gas line need upsizing?
Because appliances draw more than the existing pipe can deliver. Adding a tankless water heater, a larger range, a pool heater or a generator can exceed what the current line supports, and the symptom is appliances underperforming when several run at once. Sizing is calculated from total demand and pipe run length, not guessed, and it is a common hidden cost in tankless conversions.
