Repiping Cost in San Diego County (2026)

By Thomas, Lead Tech, over 20 years of plumbing experience.

Prices last updated October 2026

Anywhere in San Diego County and the Temecula Valley, a whole-home repipe with us typically runs $2,500-$8,000 for a smaller home (under 1,500 sq ft) with PEX, and $8,000-$15,000+ for larger homes or copper. Inside those ranges, the price moves with square footage, the number of bathrooms, the pipe you choose and how much wall we have to open and patch.

Whole-home repipe prices by home size and pipe material
Option	Typical installed price	What's included
Smaller home (under 1,500 sq ft), PEX	$2,500-$8,000	New PEX supply lines to every fixture, new shutoff valves, a pressure test, drywall access cuts and patching as quoted, and the permit where one is required.
Larger home, or copper in any size home	$8,000-$15,000+	The same scope in more pipe, more fixtures or copper, which costs more in material and takes longer to cut, fit and solder.
Partial repipe (one section or one bathroom)	Flat, written price before work starts	Replacing only the failing run, priced after we see where the bad pipe starts and stops.
Main water line from the meter to the house	Flat, written price before work starts	A separate job from the indoor repipe. See main water line repair.

Prices are starting rates and may vary based on job complexity. Your price is flat and in writing before any work starts.

What makes a repipe cost more or less?

Most of the price is labor: opening walls in the right places, running new pipe to every fixture, and closing it up again. These are the things that change how much of that labor a house needs.

Size of the home and number of bathrooms: Every bathroom, kitchen, laundry and hose bib is another run of pipe and another set of valves. A two-bath house and a four-bath house of the same square footage are different jobs.
PEX or copper: PEX is flexible, comes in long runs and needs fewer fittings, so it installs faster. Copper takes more material and more time to cut, fit and solder. That difference is why copper sits in the higher range.
Slab or raised foundation: On a raised foundation, the crawl space gives us a path for new lines under the floor. On a slab, we usually route new lines through the attic and walls instead of breaking concrete, which changes how many access openings the job needs.
Access and finishes: Open attics and closets make access easy. Finished basements, tile walls, plaster and built-in cabinets take more care around them, and every access cut has to be patched.
Drywall patching: Your written price says how access cuts are patched, so you know whether you are getting finished patches or patches ready for paint.
Permits: Work that needs a permit is permitted, and the permit is in the written price.

What is included in a flat, written repipe price?

Included in the written price

New supply pipe to every fixture listed in the quote, PEX or copper as agreed
New shutoff valves at the fixtures we repipe
A pressure test before walls are closed
Access cuts and patching as described in the quote
The permit, where the work needs one

What would change it, before work starts

Hidden damage found once a wall is opened, such as rot or a second leak
Code issues nobody could see before walls were opened
Extra fixtures or a change in pipe material that you ask for
Any change is explained and approved by you in writing before we do it

Should I repipe or keep repairing leaks?

Repair one leak. Repipe when the leaks keep coming. A single pinhole in copper or one corroded fitting is a repair, and we will price it as one.

The case for a repipe is a pattern: leaks in different rooms, rusty water from galvanized pipe, falling pressure at several fixtures, or a slab leak in a house where the rest of the pipe is the same age. At that point each repair buys time on pipe that is failing everywhere, and the repairs add up.

We show you what we found and price both paths when it is close. If a house only needs a section replaced, we say so. Our post on the signs your home needs repiping walks through what to look for.

How long does a repipe take, and can we stay in the house?

Most San Diego homes repipe in two to five days, depending on the size of the home and the pipe material.

Usually you can stay. We work room by room, restore water service at the end of each working day, and keep the house livable throughout the project. Plan for some dust where access cuts are made.

Is PEX or copper the better buy?

Both are sound choices for supply pipe. PEX costs less to install, handles hard water scale well and needs fewer fittings inside the walls. Copper costs more and takes longer, and some owners prefer it for an older home or a remodel where they want to match what is already there.

We price the option you want and tell you plainly where the difference in cost comes from, so the choice is yours.

How do I compare repipe quotes without getting surprised?

Repipe quotes only compare fairly when they cover the same pipe, the same fixtures and the same patching. Ask each company:

Is this a whole-home repipe, or only some of the lines? Which fixtures are included?
PEX or copper, and which type and size of pipe?
Are new shutoff valves at each fixture included?
How many access cuts, where, and is patching included? Patched to paint-ready or finished?
Is the permit included in the price?
Will I have water at night while the work is going on?
What could change the price after you start, and will you tell me in writing first?

Repiping cost questions

How much does it cost to repipe a house in San Diego County?

With us, a whole-home repipe typically runs $2,500-$8,000 for a smaller home (under 1,500 sq ft) with PEX, and $8,000-$15,000+ for larger homes or copper. Your exact price is flat and in writing before work starts.

Why is copper more expensive than PEX?

Copper costs more as material and takes longer to install, because every joint is cut, fitted and soldered. PEX comes in long flexible runs with fewer fittings, so the labor is lower.

Do I need to move out during a repipe?

Usually not. We work room by room and restore water service at the end of each working day, so the house stays livable.

Does a repipe include the main line from the street?

Not usually. The line from the meter to the house is a separate job with its own price. See our main water line repair page.

Can I repipe just part of the house?

Yes, when the failing pipe is confined to one area. We find where the bad pipe starts and stops and give you a written price for that section.

Is the drywall patching included?

Your written price says exactly how access cuts are patched, so you know what the walls will look like before you agree to anything.
