Get Hot Water Back — Repair or Replace
A water heater rarely fails at a convenient time. We connect you with a licensed Cornwall plumber to diagnose no-hot-water problems and quote repair versus replacement honestly — including high-efficiency and tankless upgrades suited to Cornwall's hard water. You'll get a free quote on both paths so you can decide based on the numbers, not pressure.

Repair or Replace? How to Decide
The age and the type of failure decide it. A tank over about 10 years old, or one leaking from the tank body itself, almost always warrants replacement — the steel has corroded through from the inside. A newer unit with a failed element, thermostat or igniter is usually worth repairing. Cornwall's hard water matters here: mineral scale builds on elements and accelerates tank corrosion, so local heaters often reach end-of-life a little sooner than the sticker suggests. A plumber will quote both so the choice is yours.
What a Water Heater Costs in Cornwall
A replacement tank water heater installed generally runs $1,400–$2,500+ depending on size, fuel type and any venting or code upgrades. A tankless upgrade typically runs $3,500–$5,500+, trading a higher upfront cost for endless hot water and lower standby loss. Straightforward repairs — an element, thermostat or igniter — are usually a few hundred dollars. The free quote gives the exact number for your unit.
What to Do if There's No Hot Water
For an electric unit, check the breaker first — a tripped breaker is a common, free fix. For a gas unit, confirm the pilot or igniter; if it won't stay lit, leave it and call a plumber rather than repeatedly relighting. If you see water pooling under the tank, shut off the cold-water supply valve on top of the heater and call for a quote — a tank leak only gets worse.

Water Heater FAQ
Should I repair or replace my water heater?
Tanks over about 10 years old, or leaking from the tank body itself, usually warrant replacement. Newer units with a failed element, thermostat or igniter are often worth repairing. A plumber will quote both so you can choose.
Do you install tankless water heaters in Cornwall?
Yes — connected Cornwall plumbers install and service tankless units, which suit homes that want endless hot water and lower standby loss. Venting and gas/electric capacity affect the quote.
How much is a new water heater installed in Cornwall?
A replacement tank water heater installed generally runs $1,400–$2,500+, and a tankless upgrade $3,500–$5,500+ depending on the unit, venting and any code upgrades. The free quote covers both options.
Why is my water heater leaking?
A leak from fittings or the T&P valve can sometimes be repaired, but a leak from the tank body itself means internal corrosion — that tank needs replacing. Cornwall's hard water speeds up that corrosion.
