What we do

Fireplaces services, end to end.

Every install is performed by a TSSA-licensed gas technician, vented to code, and finished cleanly — so the result looks as good as it works. Browse our recent installs on the gallery page.

Linear gas fireplaces

Sleek wide linear units that disappear into modern marble, stone, or wood feature walls.

Traditional & stone-hearth

Built-in gas fireplaces with stone, brick, or classic mantle surrounds — warm and timeless.

TV-over-fireplace builds

Coordinated install and venting so a wall-mounted TV sits perfectly above the firebox.

Replacement & relines

Swapping out aging or unsafe gas inserts; bringing venting and gas lines up to current code.

Service & repair

Pilot, ignition, fan, and venting service so an older fireplace lights and runs the way it should.

FAQ

Fireplaces questions, answered.

How much does a linear gas fireplace install cost in the GTA?
A linear gas fireplace install typically runs roughly $5,000–$12,000 as of 2026, depending on the unit, venting run, and the surround (marble, stone, wood). We give a clear quote that includes the fireplace, venting, and finish work.
Can I mount a TV above a gas fireplace?
Yes, with the right unit and venting plan. Modern direct-vent linear fireplaces are designed for TV-over installs — we choose the model and venting so heat is managed safely behind the screen.
Do you handle the surround and finishing?
We focus on the gas, vent, and firebox install — and we coordinate closely with finishers (drywall, stone, marble, woodwork). Many of our jobs are tackled as a single coordinated project so the result feels seamless.
Can you replace an old fireplace insert?
Often, yes. Aging inserts can be replaced with modern, more efficient gas units — and we make sure venting and gas lines meet current code as part of the swap.
