Water Heater Repair & Tankless Installation in Toronto & GTA — Same-Day Service
A cold shower at 6 AM in a Toronto January is not a minor inconvenience — it's an emergency. We diagnose water heater failures fast, repair what can be saved, and install new tank or tankless systems same-day when replacement is the smarter call.
Get Same-Day Hot Water ServiceTank vs. Tankless — Which Is Right for Your Home?
Standard Hot Water Tank
- Lower upfront installation cost ($800–$1,400 installed)
- Simple repair, widely available parts
- Works well for 1–2 person households with predictable demand
- Keeps a tank of hot water heated around the clock (standby heat loss)
- Typical lifespan: 10–12 years in Toronto's hard water
- Good choice when budget is the primary consideration
High-Efficiency Tankless System
- Higher upfront cost ($2,000–$3,500 installed), lower operating cost
- Heats water on demand — never runs out, even with multiple showers running
- Up to 30–40% more energy-efficient than a standard tank
- Compact wall-mounted unit frees up floor space
- Typical lifespan: 20+ years with annual descaling maintenance
- Ideal for families of 3 or more, and homes with high peak demand
Our Full Range of Water Heater Services
Emergency Repair — Same Day
No hot water, water pooling around your tank, or a pilot light that won't stay lit? We diagnose fast and carry common replacement parts on every truck — thermocouples, pressure relief valves, heating elements, ignitors — for same-visit repairs on most makes and models.
New Tank Installation
We right-size the replacement unit to your household's actual hot water demand — not just the closest unit on the truck. We remove and dispose of your old tank, install the new one to code, and commission it before we leave. Full TSSA-compliant installation documentation provided.
Tankless System Installation
Navien, Rinnai, Rheem, Bradford White — we install and commission all major tankless brands. This includes gas line sizing, venting configuration, condensate management, and flow-rate calibration for your home's fixture count. We explain optimal settings before leaving.

Calcium Descaling & Flush
Toronto's hard water builds calcium scale inside tank elements and tankless heat exchangers, choking efficiency and cutting lifespan short. Our annual flush service circulates descaling solution through the system to dissolve scale and restore full heating capacity — highly recommended every 12–18 months.
Anode Rod Replacement
The sacrificial anode rod inside your tank protects the steel lining from corrosion. When it's depleted, the tank itself starts rusting from the inside — leading to brown water and eventual failure. We inspect and replace anode rods as part of our maintenance service to extend tank life by years.
Expansion Tank Installation
Ontario building code requires an expansion tank on closed-loop plumbing systems. Without one, pressure spikes from the water heater can damage your plumbing fixtures and tank components. If your home doesn't have one, we identify this during our assessment and install it correctly.
