A whole-house repipe replaces old, failing supply lines, usually galvanized steel or corroded copper, with new PEX or copper piping throughout the home. Cost scales with the number of bathrooms and fixtures being reconnected, and PEX generally costs less than copper for both material and labor. Opening walls to run new lines means drywall patching and texture matching afterward, and the job requires a permit and inspection before it's signed off. Older San Diego homes with original 1950s-70s plumbing are the most common candidates for this work.

One or two pinhole leaks in an otherwise sound system can often be spot-repaired. Once leaks show up in multiple spots, or the pipe material itself is known to fail repeatedly, a full repipe stops the cycle of repeat repairs.

Whole-House Repipe Cost FAQ

The main cost drivers are the number of bathrooms and fixtures the new lines need to reach, whether you choose PEX or copper, and how much of the home's walls or slab need to be opened to run the new pipe. Permits and inspection are required and add to the total. Call (858) 400-4417 to get a quote from the licensed plumbers we connect you with based on your home's layout.

PEX is the more common choice today because it costs less to install and handles San Diego's hard water better than copper over time. Copper lasts a long time too and some homeowners prefer it, but it costs more in both materials and labor.

Expect some drywall to come down wherever new lines run, especially near bathrooms and the water heater. The licensed plumbers we connect you with typically coordinate the patch and texture work as part of the job, so the walls get closed back up and matched, not just left open.
