Whole-House Repipe Prices in National City
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.
Common Whole-House Repipe line items
| PEX repipe, 2 bath / ~1,500 sq ft | $4,500–$8,000 |
| Copper repipe, 2 bath / ~1,500 sq ft | $8,000–$15,000 |
| Each additional bathroom | $1,200–$2,500 |
| Drywall patch and texture | $800–$2,500 |
| Permit and inspection | $150–$450 |
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.

Sweetwater Authority water is hard, and a routine service call near National City Boulevard sometimes uncovers deeper repairs once a plumber gets a camera into the line.
Original cast iron sewer laterals common in older National City neighborhoods can hide root intrusion or collapse that only shows up once the work is underway, which changes a quote mid-job.

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.
A lot of homes near Kimball Park and Highland Avenue still run original cast iron sewer laterals from the 1950s through 70s. Once the licensed plumbers we connect you with get a camera down the line, root intrusion or a collapsed section sometimes shows up that wasn't visible from the surface.
Yes, older National City homes often pair galvanized supply lines with cast iron drains, and both add labor compared to a newer copper and PVC system. Call (858) 400-4417 and mention your home's decade built so your quote starts from an accurate baseline.
