Warning Signs

Signs your water heater needs attention

Call us if you notice any of these. Catching them early can prevent a messy failure and help you plan a repair or replacement on your own terms.

No hot water

No hot water at all, or water that never gets hot enough.

Inconsistent temperature

Water that swings hot and cold instead of staying steady.

Rusty or discoloured water

Rust-tinted hot water coming from the taps.

Rumbling or popping

Noises from sediment building up inside the tank.

Pooling or leaking

Water pooling or leaking around the base of the unit.

An aging system

A unit that is past its expected lifespan.

Repair or Replace

Repair or replace your water heater?

A good rule of thumb.

Repair

makes sense when the unit is within its expected lifespan and the issue is isolated, like a faulty part.

Replacement

is usually the smarter choice when a tank is leaking from the base, is past 8 to 12 years old, or needs frequent repairs. Upgrading is also a good moment to consider a more efficient tankless system.

Our technicians give you a straight answer based on what is best for your home, not what costs the most.

FAQ

Water heater questions, answered

How long does a water heater last?

A traditional tank water heater typically lasts around 8 to 12 years, while a tankless system can last 20 years or more with proper maintenance.

Should I repair or replace my water heater?

If your unit is within its expected lifespan and the issue is a single faulty part, repair is usually the best value. If it is leaking from the base, past its lifespan, or needs frequent repairs, replacement is often the smarter long-term choice.

Is a tankless water heater worth it?

Tankless systems cost more upfront but deliver continuous hot water, use less energy, take up less space, and last longer than tank units. For many households, the long-term savings and convenience make them worth it.

Why is my water heater making popping or rumbling noises?

These sounds are usually caused by sediment building up at the bottom of the tank. Flushing the tank can help, but persistent noise may signal it is time for service or replacement.

Why is my hot water rusty or discoloured?

Rusty or discoloured hot water often points to corrosion inside the tank, which is a sign the unit may be nearing the end of its life. It is worth having a technician inspect it.
