Hot water for the way Markham households live
Households with basement apartments, second kitchens or extended family often outgrow a standard tank. When the hot water runs out halfway through the morning, the heater may be too small, half full of scale, or both.
We repair gas and electric tanks, power-vented and high-efficiency models, and tankless units. If a repair makes sense, we fix it. If the tank is leaking or worn out, we give you a flat price to replace it, whether that is like-for-like, a larger tank, or tankless.
Every installation is sized to how many people and bathrooms the heater serves, vented properly, and tested before we leave.
Water heater services in Markham
Repair, replacement and new installations for every common type of residential water heater.
Water heater repair
No hot water, not enough hot water, a pilot that will not stay lit, a failed element, a leaking relief valve or rumbling from the tank. We find the faulty part and fix it.
Hot water tank replacement
When a tank is leaking or worn out, we remove it, install the new one to code with proper venting and shut-offs, and test it.
Water heater installation
New gas or electric tanks, power-vented and high-efficiency models, including larger tanks for homes with a basement suite.
Tankless water heater installation
Endless hot water for busy households. We confirm the gas line and venting can support a tankless unit before recommending one.
Tankless descaling and repair
Hard York Region water scales up tankless heat exchangers. Error codes and units that shut off mid-shower are often fixed with a descale and service.
Rented tank replacement
If your rented tank has failed or you would rather own one, we can install a tank you own. Check your rental agreement for how the old unit is returned.
Hard water and Markham water heaters
York Region reports that its water is usually hard or very hard, and that is hard on water heaters in Markham. Scale builds up in tanks and on tankless heat exchangers alike, so both types need regular flushing or descaling to heat efficiently and last.
Finished basements and second kitchens are common in Markham, which puts more demand on water heaters than the house was first built for. Hot water that runs out early is one of the most frequent calls we take here.
Not sure whether to repair or replace? Start with the signs your water heater is failing, and our comparison of tankless and tank water heaters covers which suits a Markham household.
Signs your water heater needs attention
- Hot water runs out much faster than it used to
- Water pooling around the base of the tank
- Rumbling, popping or banging as the tank heats
- Rusty or discoloured hot water
- A pressure-relief valve that drips or discharges
- A tank that is 10 to 12 years old or more
Hard water speeds up most of these. Our guide to hard water in York Region explains what it does to your plumbing.

What affects the cost of a water heater
Every job is quoted on site after we see the heater and the space it sits in. You approve a flat price before work begins. The main factors are:
- Repair or replacement, and which part has failed
- Tank or tankless, gas or electric, and the size you need
- Venting: a standard chimney vent, power vent or direct vent
- Gas line size and whether it needs upgrading for a tankless unit
- Access to the heater and the space around it
There are no dispatch fees or overtime charges. See how our diagnostic and flat pricing works.
