Could be a faulty thermostat, sediment buildup, or element failure. We test all three.

Is it dangerous to ignore water heater issues?

Yes — leaking tanks or failed relief valves can cause flooding or pressure hazards.

Most jobs take 1–2 hours. We’ll give you an exact timeline after diagnosis.

Will you have the parts on hand?
