Water Heater Service
Water heater problems usually show up as no hot water, not enough hot water, or a visible leak. We diagnose whether the fix is a component (thermostat, element, ignitor, valve) or a full replacement, and explain the tradeoffs.
Accurate pricing is provided after an on-site plumbing inspection. Repair options and pricing are explained before approved work begins.

FAQs about water heater service
Is a leaking tank always end of life?+
A leak from the tank itself usually is. A leak from a valve or fitting is often repairable.
Tank or tankless, which is better for me?+
It depends on hot water usage, gas/electric availability, and budget. We walk through it before recommending anything.
Why does my water heater rumble?+
Usually sediment build-up. A flush can help; a heavily corroded tank may need replacement.
How long does a water heater replacement take?+
A like-for-like tank replacement is usually completed in a single visit. Tankless conversions take longer.
