Zone 3C — Warm-Marine (coastal). Along the coast, the plumbing problems we hear about most are aging supply lines in older housing stock, corrosion on exposed fittings from salty marine air, and sewer laterals invaded by roots from mature street trees. Hard freezes are rare in San Francisco, so burst pipes are unusual — slow slab leaks and drain blockages are the more common emergencies.

FAQ

Common questions

Are the plumbers licensed?

We connect you with independent licensed, insured plumbers. California requires a CSLB license (C-36) for plumbing jobs of $500 or more — and we recommend verifying any license at cslb.ca.gov before work begins; see our guide.

How fast can someone get to San Francisco?

Response times depend on provider participation, location, technician availability, and demand. Emergency calls are prioritized; when you call, we tell you honestly what's available for San Francisco right now.

Why do older homes in San Francisco have low water pressure?

Many homes in coastal San Francisco County were built with galvanized steel supply lines. Decades of internal corrosion narrows the pipe and drops pressure. A licensed plumber can confirm the material and advise whether a repipe makes sense.
