Water Heater Installation & Replacement

We install both natural gas and electric tank-style and tankless water heaters, ensuring every system is properly sized, safely connected, and optimized for long-term reliability. Whether you’re replacing a worn-out unit or upgrading to an energy-efficient model, we’ll help you choose the right solution for your home or business. For seasonal cottages and rural properties, we also provide propane water heater installations for safe, reliable hot water where natural gas service isn’t available.

Water Heater Repairs

No hot water? Leaks? Inconsistent performance? We provide fast, accurate diagnosis and repair for all major water heater brands and models. From pilot light and ignition issues in gas units to thermostat or heating element problems in electric systems, we restore safe and reliable hot water with minimal downtime.

Tankless Water Heaters

Looking for on-demand hot water and higher efficiency? We install and service tankless water heater systems that deliver comfort without the bulk of a storage tank. Our installations are completed to manufacturer specifications and Ontario safety codes, giving you dependable performance for years to come.

Water Heater Maintenance

Routine maintenance extends the lifespan of your water heater and helps prevent costly breakdowns. Our service includes inspection, flushing (where applicable), and performance checks to keep your system operating efficiently and safely.

Emergency & Same-Day Support

When hot water stops flowing, it can disrupt your whole household or business. We provide fast, responsive service for urgent water heater issues — prioritizing no-hot-water calls so you’re back up and running as quickly as possible.
