Gas work

Gas fireplace service and gas lines in Ottawa

Every gas appliance in an Ontario home, from the fireplace in the family room to the barbecue on the deck, has to be connected by a TSSA-certified technician. We service and install fireplaces and run gas lines for ranges, dryers, pool heaters, outdoor kitchens and generators across Ottawa, Stittsville, Gloucester and the surrounding communities.

The fireplaces in the subdivisions

Almost every house built in Kanata, Barrhaven, Orléans and Stittsville from the 1990s on came with a builder-installed direct-vent gas fireplace, and most of them have never been serviced. Twenty years in, the pilot assembly is dusty, the thermopile is tired, the glass gasket has hardened and the blower rattles. A service cleans and tests all of that, replaces the gasket and any weak parts, and leaves the fireplace lighting first time. We also replace fireplaces and inserts outright, and fit new direct-vent units where there was none.

When a fireplace will not light, the suspects in order are the pilot, which may simply need relighting; the thermocouple or thermopile, which may no longer hold the valve open; the wall switch or remote receiver; and a pilot clogged after a summer of sitting idle. All are short visits. September and October are the months to book, before the November rush.

Gas lines for ranges, dryers, barbecues and pool heaters

New black-iron or CSST runs for kitchen ranges, clothes dryers, barbecues, outdoor kitchens, patio heaters, and pool and hot-tub heaters. Every line is sized for the appliance, pressure-tested and inspected as the Ontario Gas Utilization Code requires. A barbecue line from an existing supply in the basement to the deck is typically $450 to $900 installed in the Ottawa area in 2026; a pool heater or an outdoor kitchen depends on the distance and the pipe size and is quoted in writing after a look at the route. The same rules govern the supply to a new furnace or water heater.

Standby generators

The 1998 ice storm, the 2018 tornadoes and the 2022 derecho each left parts of Ottawa without power for days, and standby generators on natural gas or propane have become one of the most common gas-line requests in the region. We run the supply line, size it for the generator's full load, and coordinate with your electrician on the transfer switch. Propane-fed generators for Manotick and the rural south are connected the same way.

Common questions on fireplaces & gas lines

My gas fireplace will not light. What should I check?

Check that the wall switch or remote has power and that the gas valve on the supply line is open. If the pilot is out and will not stay lit, the thermocouple or thermopile has usually weakened and cannot hold the valve open, or the pilot assembly is clogged with dust after a summer idle. Those are a short fireplace service visit: the pilot assembly is cleaned, the thermopile output measured and replaced if low, the burner and logs reset and the glass cleaned. Book it in early fall; the calls pile up in November.

Do I need a permit to run a gas line in Ottawa?

The gas piping itself does not take a City of Ottawa building permit, but under Ontario law it must be installed by a TSSA-certified gas technician, pressure-tested, and inspected when it serves a new appliance. The appliance on the end of the line sometimes brings its own permit: a standby generator needs an electrical permit, and a pool heater or an outdoor fireplace may need a building permit. We handle the gas side and tell you what else applies before the work starts. See gas lines.

What does it cost to run a gas line to a barbecue in Ottawa?

A straightforward run from an existing basement supply to a quick-connect on the deck is typically $450 to $900 installed in Ottawa in 2026. A long run, a pool heater, a garage heater or a standby generator needs larger pipe and is quoted in writing after a look at the house. Every run is pressure-tested, and the quick-connect is fitted with a shut-off so the barbecue can be disconnected for winter. See gas lines.
