Common Water Heater Repair Problems in San Mateo
No hot water at all
A failed heating element, pilot light issue, or thermostat failure. We'll diagnose and restore hot water same day.
Water not hot enough
Sediment buildup, a failing dip tube, or thermostat issue can reduce temperature. We'll restore proper heating.
Water heater leaking
Tank corrosion, loose fittings, or a faulty T&P valve can cause leaks. We provide leak repair and replacement guidance.

Sediment buildup at the bottom of the tank causes these sounds. We'll flush the tank and inspect for damage.
