Professional Gas Fireplace Repair in St. Louis
A gas fireplace is simple to use, but there is a lot going on behind the glass: a gas valve, a pilot assembly, a thermocouple or thermopile, an igniter, a remote receiver, a burner and a venting system that has to pull exhaust out of the house. When one of these parts fails, the fireplace stops lighting, shuts off after a few minutes, or burns with a lazy, sooty flame.
Our technicians test each part of the system instead of guessing. We check gas pressure, clean the pilot and burner, measure the millivolt output of the thermocouple and thermopile, inspect the vent and the glass gasket, and test the remote, wall switch and batteries. You get a clear explanation of what failed and an upfront price before any repair starts. We work on direct-vent, B-vent, vent-free and gas insert models, and we also offer pilot light and ignition repair, gas log repair and yearly gas fireplace maintenance.

Gas Fireplace Problems
Signs Your Gas Fireplace Needs Repair
Call a gas fireplace technician if you notice any of these problems:
- The pilot light will not light or will not stay lit
- The fireplace clicks but the burner never ignites
- The flame shuts off after a few minutes of running
- Yellow, tall or lazy flames, or black soot on the glass or logs
- The remote control or wall switch no longer turns the fireplace on
- A smell of gas, or a strong burning or chemical smell that does not go away
If you smell gas, do not try to light the fireplace. Leave the house and call 911 or your gas company from outside first.

Venting, Gas Leaks and Carbon Monoxide
A gas fireplace produces carbon monoxide and water vapor while it burns. If the vent is blocked by a bird nest, debris or a damaged cap, or the glass gasket has failed, exhaust can spill back into the room. Weak or yellow flames and soot on the glass are early warnings that something is wrong with combustion or venting.
As part of every gas fireplace repair we inspect the vent termination, the cap, the liner connection and the glass seal, check the gas connections for leaks, and confirm the flame looks right. Every home with a gas fireplace should also have working carbon monoxide detectors. Need the chimney or vent checked too? Book a chimney inspection.

FAQ's
Frequently Asked Questions
Why won't my gas fireplace turn on?
The most common causes are a pilot light that is out, a dirty or weak thermocouple or thermopile, dead remote or receiver batteries, a closed gas valve, or a failed igniter. A technician can test each part and find the cause quickly.
Why does my gas fireplace shut off after a few minutes?
This is usually a safety device doing its job. A weak thermopile, a dirty pilot flame or a vent problem that trips the spill switch can all shut the burner off. These need to be tested, not bypassed.
Is it safe to repair a gas fireplace myself?
Changing remote batteries and relighting the pilot by following the manufacturer’s instructions is fine. Work on gas valves, gas lines, burners and venting should be done by a trained technician because a mistake can cause a gas leak or carbon monoxide problem.
Do you repair all gas fireplace brands?
We service most common gas fireplace, insert and gas log brands. Tell us the make and model when you call so we can bring the right parts when possible.
How often should a gas fireplace be serviced?
Once a year, ideally before the heating season. Our gas fireplace maintenance visit cleans and tests the whole system and catches small problems early.
