Water Heater Repair in San Francisco, California

The usual rule of thumb: if the unit is under about 8 years old and the failure is a component, repair. If it is over 10–12 years old, or the tank body is leaking, replacement is almost always the better spend. Ask the contractor for the manufacture date from the serial number.

That smell is normally sulfate-reducing bacteria reacting with the magnesium anode rod. Replacing the anode rod with an aluminum-zinc rod and sanitizing the tank usually resolves it. It is not a gas leak — but if you smell gas rather than sulfur, treat it as an emergency.

A conventional tank unit commonly lasts 8–12 years; tankless units are generally rated longer. Water hardness has a large effect — in hard-water areas, annual flushing matters.

Permits in San Francisco are issued by San Francisco Department of Building Inspection (DBI). As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.

Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering San Francisco can triage the urgency and bring the right parts.

Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.

The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.

Whatever the contractor offers in writing — PlumberCalifornia is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
