Gas fireplace installation & service
across Toronto & the GTA
A gas fireplace is a gas appliance that happens to live in your living room. It should light first time, burn clean, and be inspected once a year like anything else on the gas line.

Gas fireplaces that look sharp and burn clean
Sooting glass, a lazy yellow flame or an odour at start-up are all telling you the same thing: combustion is not right. Cleaning the glass treats the symptom. We look at the burner, the pilot assembly and the venting termination, because that is where the cause almost always is.
Autumn is when the annual service calendar fills up, and most of the December call-outs we attend are for something a September visit would have found — a blocked termination cap, a tired thermocouple, a pilot that was already struggling.
On new installations and wood-to-gas conversions the work that matters is mostly invisible afterwards: framing clearances, the gas rough-in, and an exterior termination that respects snow lines and the neighbour's windows. Finished rooms get covered before we start.
What matters most for gas fireplace installation in the GTA
Right sizing, licensed gas/refrigeration work, and commissioning beat the cheapest sticker price. We verify airflow, safety devices, condensate paths, and controls so your system does not fail the first extreme week of the season. Ask us about dual-fuel, zoning, and rebate-eligible models during your quote.
Efficiency notes for hearth upgrades
While fireplace-specific rebates are less common than furnace or heat pump programs, high-efficiency heating upgrades elsewhere in the home may still qualify. Review HVAC rebates & incentives when budgeting a broader retrofit.
Fireplace service triggers
- Pilot will not stay lit or igniter clicks without flame
- Black sooting on glass or ceramic logs
- Unusual odours at startup or shutdown
- Flame looks lazy, yellow, or uneven across the burner
- Remote or wall switch no longer responds
- Glass is cloudy and cleaning products are not enough
- You are renovating and want a modern insert
- Annual safety check is overdue before winter entertaining

Maintenance & safety
What an annual fireplace service covers
A gas fireplace is a gas appliance in a living room. These are the checks that keep it one you do not have to think about.
Annual inspection by a licensed technician
Gas appliances are inspected annually. On a fireplace that means the burner, pilot assembly, igniter, gas connections and controls checked and tested as a set, by a TSSA-licensed technician.
Venting and termination
The vent run and its exterior termination are checked for blockage, corrosion and clearance. Snow lines, nests and renovation work over the summer are the usual culprits behind an autumn lockout.
Carbon monoxide alarms
Ontario law requires a working CO alarm near sleeping areas in homes with a fuel-burning appliance. We check that one is present and in date — it is the backstop for everything else on this list.
Clearances to combustibles
Mantels, televisions, decorations and furniture move over the course of a year. Clearances are re-checked against the appliance listing, not against how the room looked at installation.
Glass front and screen
The glass on a direct-vent fireplace gets hot enough to injure. Where there are young children we will talk through barrier screens, which many units accept as an accessory.
Combustion and flame picture
Sooting glass, a lazy yellow flame or an odour at startup all indicate incomplete combustion. These are diagnosed rather than wiped off, because the appearance is a symptom and not the fault.

Client reviews
Fireplace clients share their experience
Our insert would not stay lit through dinner parties. They replaced the thermopile, cleaned the burner, and the flame is crisp again — glass spotless.
Forest Hill
Zero-clearance fireplace for our basement reno. Coordinated gas and vent perfectly with our builder's framing schedule.
Burlington
Converted an old wood opening to a modern gas insert. Looked showroom-ready and they walked us through remote operation carefully.

FAQ
Gas fireplace FAQ — Toronto
How often should a gas fireplace be serviced?
Annual service before winter is ideal: clean burners, verify ignition safety, inspect venting, and check for leaks. Heavy-use units may need attention mid-season.
Why is my fireplace glass turning black?
Soot usually means incomplete combustion — misaligned media, dirty burners, incorrect pressure, or venting issues. Do not ignore it; we clean and correct the root cause.
Can I install a gas fireplace in a condo?
Only when the building and unit allow venting and gas work. Many condos restrict or prohibit new terminations. We review rules before ordering equipment.
What is direct-vent versus B-vent?
Direct-vent sealed systems draw combustion air from outdoors and exhaust outdoors — preferred for modern installs. B-vent relies on indoor air and a chimney draft; we advise carefully on existing B-vent units.
Do gas fireplaces need electricity?
Millivolt systems can run without household power (useful in outages). Electronic ignition and blowers need power or battery backup — we explain which you are buying.
Can a fireplace heat my whole house?
Unlikely as a primary system. It can warm an open main floor zone. Whole-home heat still belongs to a furnace, boiler, heat pump, or radiant plant.
How do I request a fireplace quote?
Share photos of the existing opening or proposed wall, plus your gas availability. Start via contact us or call 647 953-4252.
How much does gas fireplace installation cost in Toronto?
Cost depends on equipment capacity, brand, duct or piping complexity, electrical/gas upgrades, and whether you repair or replace. We provide written quotes after a site assessment so you can compare options fairly. Call 647 953-4252 for a visit.
Do you serve my area in the GTA?
Yes. We are based in North York at 132 Cartwright Ave and regularly serve Toronto, Mississauga, Vaughan, Markham, Scarborough, Etobicoke, Brampton, and nearby communities.
Are your technicians licensed?
Yes. Gas and refrigeration work is performed by TSSA-licensed technicians. We follow Ontario code practice for venting, refrigerant handling, electrical disconnects, and condensate management.
