Water Heater Repair: Common Questions

My water heater is leaking from the bottom — repairable?

If the tank itself is leaking, no — tanks aren't repairable, and it will get worse. If it's a valve or fitting leaking, that's a cheap fix. A pro can tell in minutes; don't wait, tank failures flood.

What does a new water heater cost here?

Roughly $1,800–$3,500 installed for a standard tank in Western Washington; tankless conversions and heat-pump units run higher. See our water heater cost guide for the full breakdown.

How do I check a company's license?

Ask for their Washington L&I contractor number and verify it at secure.lni.wa.gov/verify — active license, bond, and insurance. Listings above with a green badge are ones we've already matched to an active license in state records.
