About our gas fireplace installation service

We install gas fireplace inserts (replacing old wood-burning fireplaces), zero-clearance units for new construction, and free-standing stoves. Every install is permitted, pressure-tested, vented to manufacturer spec, and safety-verified.

Fireplaces here get installed for two very different reasons: ambience in the newer Snow Valley and Horseshoe Valley builds, and genuine backup heat in shoreline cottages around Lefroy and Big Bay Point where a winter power outage can last a day. That difference changes the recommendation. If you want heat when the grid is down, you want a millivolt or battery-backed ignition, not an electronic system that dies with the power.

What's included

  • Inserts, zero-clearance, and free-standing
  • Direct-vent and B-vent installations
  • Remote or wall-switch operation
  • Permitted and TSSA-inspected

Where we provide gas fireplace installation

Innisfil is home base, and our trucks run the same routes daily across Simcoe County and north York Region.

  • Barrie Barrie's older housing stock has plenty of undersized or aging gas piping that needs upgrading before a new appliance can be connected safely.
  • Bradford West Gwillimbury Bradford's larger family households burn through hot water fast, which is why tankless conversions are popular there.
  • Essa Rural Essa properties north toward Newton Robinson are frequently on propane, and appliance conversion has to be done and documented properly.
  • East Gwillimbury Newer East Gwillimbury homes commonly arrive with a rental water heater the owner would rather replace and own outright.
  • Springwater Hard well water through Springwater scales tanks and tankless heat exchangers, so we plan descaling into every install we do out there.
  • Newmarket Newmarket's finished basements make appliance venting routes the deciding factor in what equipment can actually go in.
  • Oro-Medonte Seasonal and cottage properties around Oro-Medonte need equipment and gas work that tolerates being shut down for months at a time.
  • New Tecumseth Alliston and Beeton homes often pair a gas fireplace with the main heating system, and both need annual attention to keep venting safe.
