Common Gas Fireplace & Gas Insert Problems We Fix
Gas fireplaces and gas inserts are convenient and efficient, but like any gas-burning appliance, they need a trained technician when something goes wrong. Our CSIA and NFI certified technicians regularly diagnose and repair:
- Pilot light won’t light or won’t stay lit. Often caused by a dirty or misaligned pilot assembly, a failing thermocouple or thermopile, or a weak gas valve.
- No flame or a weak, low flame. Usually linked to a clogged burner, a gas pressure issue, or a blocked orifice.
- Clicking or ticking sounds when trying to ignite. A common sign of an igniter or ignition module problem.
- Uneven, yellow, or lazy flames. Can point to a dirty burner, air-mixture problem, or ventilation issue that needs prompt attention.
- Soot buildup, a burning smell, or streaks on the glass. Often caused by incomplete combustion and should be inspected before regular use continues.
- Blower or fan not working. Reduces the heat you actually feel in the room even when the fireplace is running.
- Gas odor or a suspected leak. If you smell gas (often described as a rotten-egg odor), turn off the appliance, leave the area, contact your gas utility, and call our team right away.
Gas Insert Repair: What Makes It Different
A gas insert is a self-contained unit installed inside an existing wood-burning fireplace, which means repairs often involve the surround, the liner connection, and the seal between the insert and your existing masonry or prefab firebox — not just the burner and controls. Our technicians are experienced with the leading insert brands and know how to diagnose problems specific to retrofit installations, including venting restrictions, fan and blower assemblies unique to insert models, and surround or trim panel issues that can affect performance and appearance.
Warning Signs You Shouldn’t Ignore
Some gas fireplace and insert problems are more than an inconvenience — they’re a safety issue. Call a professional promptly if you notice any of the following:
- A persistent gas smell, even a faint one
- Soot, dark streaks, or discoloration around the appliance or on the glass
- The appliance shutting off unexpectedly or failing to stay lit
- Visible damage to the glass, logs, or burner components
- Unusual sounds during ignition or operation
What Does Gas Fireplace or Insert Repair Cost?
The cost of repairing a gas fireplace or insert depends on the issue, the age and brand of your unit, and the parts required. Minor fixes, such as cleaning a pilot assembly or adjusting a flame, are typically less involved than replacing a thermocouple, gas valve, or blower motor. Our technicians will inspect your appliance, explain exactly what’s wrong, and walk you through the repair options and costs before any work begins — no surprises.

Frequently Asked Questions
Why won’t my gas fireplace pilot light stay lit?
The most common causes are a worn or dirty thermocouple/thermopile, a misaligned pilot assembly, or a weak gas valve. A technician can pinpoint the exact cause and usually resolve it in a single visit.
Is it safe to keep using a gas fireplace with pilot light problems?
We recommend having it inspected before continuing regular use. Pilot light issues can sometimes indicate a ventilation or gas-flow problem, and a professional inspection ensures your appliance is operating safely.
How often should a gas fireplace or insert be serviced?
Most manufacturers recommend annual maintenance, ideally before the start of heating season, to catch small issues before they become bigger repairs. Learn more on our gas fireplace & insert maintenance page.
Do you repair gas inserts as well as freestanding gas fireplaces?
Yes. We repair gas fireplaces, gas inserts, and gas stoves. If your issue is with a freestanding gas stove specifically, visit our gas stove repair page.
