What a whole-house repipe really costs in San Diego County

The short answer: in 2026, a whole-house repipe in San Diego County typically runs $4,500–$9,500 for PEX and $8,000–$15,000 for copper on a standard 2–3 bathroom home, including permits. Drywall repair is usually quoted separately and adds roughly $1,000–$2,500.

Now the longer answer — because the range is wide, and where your house lands depends on things you can actually understand.

What moves the price up or down

Fixture count, not square footage. A repipe is priced by how many things connect to water: every sink, toilet, shower, hose bib, ice maker and laundry hookup. A 3-bath house with a wet bar and two outdoor spigots costs more to repipe than a bigger house with fewer fixtures.

One story or two. Two-story homes mean longer runs and more routing work — typically 15–25% more.

Access. Homes with attic or crawlspace access repipe faster and cheaper. Slab-on-grade homes (most of North County's 60s–80s tract stock) route overhead through walls and attic, which is exactly the kind of work press-fit tools were made for.

Material. PEX runs about half the price of copper, installs with fewer wall openings, and — important around here — doesn't pit and pinhole the way copper does in our soil and water. Copper remains a great premium product, and some homeowners simply prefer it. We install both and we'll tell you honestly: for most North County repipes, PEX is the smart money.

Permits and inspection. A legitimate repipe is permitted and inspected. If a bid seems suspiciously low, ask directly whether permits are included. (Ours are.)

The San Diego wrinkle: why so many homes here need this

North County boomed in the 1960s–80s, and those homes were built with thin-wall M-type copper — often run under the slab. Between our alkaline soil, water chemistry and 40–60 years of service, that copper is failing on schedule: first one pinhole slab leak, then another. If your neighbors are getting repipes, it's not a sales wave — it's the same builder, same pipe, same year, all aging out together.

When you DON'T need a repipe

Plenty of plumbers jump straight to the biggest ticket. Here's our honest checklist:

• First-ever leak, otherwise healthy copper? A spot repair or single-line reroute is usually the right call — a fraction of the cost.
• Low pressure at one fixture only? That's a valve or fixture problem, not a piping problem.
• Selling soon? A targeted repair plus full disclosure sometimes beats repiping a house you're leaving — we'll talk it through with you honestly.

But if you're on your second or third leak in a few years, have rusty water from galvanized pipe, or found polybutylene in your walls — stop paying for the same emergency on an installment plan. That's when a repipe saves money.

What a repipe looks like with us

Day one: protect floors and furniture, cut clean access openings, run the new system. You have water that same night. Day two (and sometimes three): finish connections, pressure-test everything, city inspection. Then patching brings the walls back. A typical 2–3 bath North County home is a 2–3 day job — not weeks of chaos.
