Repipe Cost in San Francisco

There's no honest flat price for a whole-home repipe in San Francisco, because the cost is driven by your home — its size, how many fixtures it feeds, how hard the pipes are to reach, and the material you choose. What we can do is explain exactly what moves the number, then give you a firm, upfront quote with no surprises.

What "repiping" actually means

Repiping replaces the water supply lines that run through your walls, floors, and ceilings — the pipes that carry fresh water to every faucet, shower, and appliance. In older SF homes those original lines are often galvanized steel, which corrodes from the inside out over decades. (Repiping is different from sewer/drain work, which carries water away — see your sewer lateral guide.)

When repiping is the right call

• Weak, falling pressure throughout the house (classic corroded-galvanized symptom).
• Rusty or discolored water, especially on the first draw of the day.
• Repeated pinhole leaks — fixing one only for the next to appear.
• A remodel that already opens walls, making it the efficient time to repipe.

What changes the price

These are the real cost drivers — the reason two "repipes" can land at very different numbers:

• Home size & fixture count. More bathrooms, kitchens, and runs = more pipe and labor.
• Material. Copper and PEX have different material and labor costs and different lifespans.
• Access. The single biggest swing factor — open crawlspaces and basements are far easier than finished plaster walls and tight Victorian framing.
• Stories & layout. Multi-level flats and stacked units add complexity.
• Permits & inspection. Required, and part of doing it right.
• Finish restoration. Patching the walls and surfaces opened during the work.

Anyone quoting a precise dollar figure sight-unseen is guessing. Typical SF repipe ranges depend heavily on the factors above — which is why we price it after seeing the home, not before.

What we see in San Francisco homes

Across the pre-1960 housing stock we work in, galvanized supply lines are the most common reason a whole-home repipe comes up — and access is almost always the factor that determines whether a job is straightforward or involved. Our approach is to scope the home, walk you through the material trade-offs, and put it all into a single upfront price. That's the Cabrillo promise: the price we quote is the price you pay.

How to get your actual number

The only way to a real repipe price is an in-home assessment. It's the fastest path to a firm quote — and if you already have a bid from another company, we're glad to give you a free second opinion on it.
