Gas Lines & Water Tanks Installation:

In 2026, working with natural gas and hot water systems in Ontario requires TSSA certification and strict adherence to safety codes. These Labor-Only rates cover professional installation, pressure testing, and certification for your home’s critical energy systems. Prices are per Unit/Installation.

1. Gas Line Installation (Stove, BBQ, Dryer)

Safety is the absolute priority when running fuel lines. Labor costs depend on the length of the pipe run, the complexity of the route, and the demand of the appliance.

• Below Market ($400 – $600/line): Running a new gas line up to 15ft through an unfinished basement. Ideal for adding a gas stove or dryer near the existing main line.
• Market Range ($600 – $1,300/line): The benchmark for BBQ hookups or gas fireplaces. Includes drilling through brick/foundation, proper outdoor mounting, and high-quality shut-off valves to ensure a leak-proof system.
• Above Market ($1,300 – $2,500+/line): Complex runs for pool heaters, standby generators, or outdoor fire pits requiring specialized trenching and heavy-duty gas piping (CSST).

2. Water Tank Replacement (Standard)

A proper tank installation ensures consistent water pressure and prevents catastrophic leaks. Labor includes the careful handling of both gas and water connections.

• Below Market ($550 – $800/unit): Replacing an old tank with a similar model in the same location. Includes disconnection of the old unit and basic reconnection to existing lines.
• Market Range ($800 – $1,500/unit): The professional standard. Includes installation of a new tank, replacement of aging shut-off valves, and thermal expansion tank setup to protect your home’s plumbing from pressure spikes.
• Above Market ($1,500 – $2,500+/unit): Required if converting from a traditional chimney-vent to a high-efficiency Power Vent system, or if the unit needs to be moved to a different area of the home.

3. Tankless Water Heaters (On-Demand)

The gold standard for modern Ontario homes, providing endless hot water while saving significant space in the mechanical room.

• Below Market ($1,000 – $1,600/unit): Swapping an existing tankless unit for a new one. Assumes all gas, water, and venting infrastructure is already in place and meets 2026 codes.
• Market Range ($1,600 – $3,000/unit): The most common upgrade. Includes wall-mounting the unit, upsizing the gas line for high-demand flow, and installing a dedicated venting system and condensate drain.
• Above Market ($3,000 – $5,000+/unit): Advanced setups with internal pumps for “instant” hot water at every tap, or complex installations in large estates requiring multi-unit coordination.
