Why Professional Gas Fitting Matters
Gas is the most dangerous utility in your home. A single improperly fitted joint can leak natural gas or propane into your living space — causing explosions, carbon monoxide poisoning, and fatal house fires. Every year, DIY gas work and unlicensed handyman installs cause preventable tragedies.
Licensed gas fitters pressure-test every connection, verify proper pipe sizing for BTU demand, install code-required shut-off valves, and ensure your gas system is safe before turning on a single appliance. There are no shortcuts with gas work.
Explosion Prevention
Every joint tested under pressure
CO Protection
Proper venting & combustion air
Code Compliance
WA state gas code certified
Gas Fitting FAQs
Common gas fitting questions answered by our licensed experts serving Whatcom & Skagit Counties.
Can I do gas work myself?
Absolutely not. Gas fitting requires a licensed professional by Washington state law. Improper gas work causes leaks, explosions, carbon monoxide poisoning, and house fires. Never attempt DIY gas work.
How much does a gas line installation cost?
A simple gas line run (under 25 feet) typically costs $300–$800. Longer runs, multiple appliances, or attic/crawlspace routing ranges $800–$2,500+. We always provide an upfront quote before starting.
Can you run a gas line for my BBQ?
Yes — we run permanent gas lines from your meter to outdoor grills, fire pits, and patio heaters. No more refilling propane tanks. Properly buried, protected, and code-compliant.
What should I do if I smell gas?
Leave the building immediately. Do not flip light switches, use phones, or start vehicles near the building. Once safely outside, call 911 first, then call us at 360-685-8098 for 24/7 emergency response.
Can you convert my electric range to gas?
Yes — we run a new gas line from your meter or nearest supply point to your kitchen, install a shut-off valve, connect the range with a proper flex connector, and pressure-test everything.
Do you work with propane systems too?
Yes — we install and repair both natural gas and propane systems. We handle propane appliance hookups, tank line connections, regulators, and conversions between fuel types.
How do you test gas lines for leaks?
We perform a pressure test on every gas system after installation or repair. The line is pressurized and held for a set duration — any pressure drop indicates a leak that we locate and fix before gas is turned on.
Can you hook up my gas fireplace or insert?
Yes — we connect gas fireplaces, inserts, and log sets. We run the gas line, install the shut-off valve, connect the unit, and verify proper venting and combustion air before lighting.
What areas do you serve for gas fitting?
We provide gas fitting services across all of Whatcom and Skagit Counties including Bellingham, Mount Vernon, Anacortes, Burlington, Sedro-Woolley, Ferndale, Lynden, and surrounding areas.
