More about gas fireplace service
What gas fireplace service includes
A standard gas fireplace service includes cleaning the burner ports and log set, inspecting and testing the pilot assembly and ignition system, checking the thermocouple or thermopile, cleaning the glass panel, inspecting the gasket and door seal, and verifying proper venting. We test the fireplace through a full startup cycle before we leave.
Common gas fireplace problems we diagnose and fix
Pilot won't stay lit — usually a failed thermocouple or thermopile. Ignition clicks but won't light — often a dirty or misaligned pilot. Flame is weak or uneven — clogged burner ports. Glass keeps hazing — combustion products not venting properly. Remote or wall switch doesn't work — receiver or wiring issue. We diagnose the actual problem and fix it, rather than recommending replacement when repair is the right answer.
Gas fireplace installation
We handle full gas fireplace and insert installation — from framing and liner sizing through the final test fire. We work with direct-vent, natural-vent, and vent-free units depending on your application. We'll help you understand the right unit type for your space before the work starts.
Common Questions
How often should a gas fireplace be serviced?
Annually. Even though gas burns cleaner than wood, dust and debris still accumulate in burner ports, and ignition components wear over time. Annual service catches these issues before the fireplace fails mid-season.
My gas fireplace pilot won't stay lit — what's wrong?
Most commonly, a pilot that lights but won't stay on is a failed thermocouple — the safety sensor that tells the gas valve the pilot is on. It's a relatively straightforward repair. We'll diagnose it properly before recommending any parts.
Can you service a gas fireplace that hasn't been used in years?
Yes. If the fireplace has been dormant, we'll do a thorough inspection and cleaning before recommending restoration to service. Spiders and insects commonly nest in gas components during extended periods of non-use and need to be cleared before lighting.
Do you install gas fireplace inserts?
Yes. We handle full gas insert installation — including liner sizing and installation, framing, surround work, and final testing. We'll help you select the right insert for your existing fireplace opening.
