Gas Fireplace Repair in Newmarket
Most gas fireplace failures are small, electrical and completely predictable at a certain age. A thermopile that has dropped below the millivolt threshold, a pilot hood shifted a few millimetres off the sensor, a dirty flame rectification probe, a glass gasket that has gone hard and broken the sealed-combustion circuit. All are same-visit repairs when the technician arrives with the parts.

What we do
Gas Fireplace Repair in Newmarket — how it works
We are licensed G2 gas technicians, so diagnosis includes the things a general handyman cannot legally do: manifold and inlet pressure readings, spillage and combustion checks, and a proper safety-circuit test. If your fireplace has a carbon monoxide or venting issue, that is what finds it.
Signs you need this service
- Pilot lights but the main burner will not come on
- Fireplace runs for ten to fifteen minutes then shuts off
- Pilot will not stay lit at all
- Remote or wall switch does nothing, but a match works
- Soot on the glass, or a lazy yellow flame
- Blower noisy, rattling or not running
- Gas smell, or a carbon monoxide alarm near the unit
What's included
- Burner, pilot and logs cleaned as part of the repair
- Glass removed, cleaned and re-gasketed where required
- Venting and termination inspection
- CO test at the appliance
- Written report with the readings taken
Our process
Step by step, start to finish
- Step 1
Safety check first
Gas leak check, CO reading and venting inspection before anything is dismantled.
- Step 2
Electrical diagnosis
Millivolt output at the thermopile, valve continuity, switch and wiring tested.
- Step 3
Combustion and pressure
Manifold and inlet pressure measured against the manufacturer's spec plate.
- Step 4
Repair with stocked parts
Thermopiles, thermocouples, pilot assemblies, gaskets and igniters carried on the truck.
- Step 5
Full cycle verification
The unit runs a complete cycle on the actual control before we leave, with readings recorded.

Local knowledge
What this looks like around Newmarket
Glenway, Stonehaven, Summerhill and the Aurora Bayview builds are full of 1990s and 2000s zero-clearance units now hitting the age where the thermopile, pilot assembly and glass gasket all fail within a couple of seasons of each other. Doing them together on one visit is cheaper than three trips.
Newer Woodland Hill, Queensville and Stouffville homes are direct-vent with low sidewall terminations. Snow drifting over the termination is the single most common winter lockout in those neighbourhoods, and it is a five-minute fix once you know to look.
FAQs
Questions homeowners ask us
Why does my gas fireplace shut off after 10 minutes?
Almost always a weak thermopile or a pilot flame that has drifted off the sensor. The safety circuit reads the millivolt drop and closes the valve exactly as designed. It is a same-visit repair, typically $180 to $380.
How much does gas fireplace repair cost in Newmarket?
$180 to $600 for the vast majority of repairs. The diagnostic fee is $120 to $180 and is credited against the repair when you approve it. Gas valve replacements are the main exception at $450 to $850.
How often should a gas fireplace be serviced?
Every two years for occasional use, annually if it is a primary heat source. Service covers the burner, pilot assembly, glass gasket, venting and a CO test — the parts that fail quietly rather than dramatically.
Do you service all brands?
Napoleon, Valor, Regency, Continental, Marquis, Montigo, Heat & Glo, Majestic, Mendota and Kozy Heat, plus builder-grade zero-clearance units installed across York Region since the 1990s.
