The Short Answer
For most single-family homes in Orange County, a whole-house repipe runs roughly $4,500 to $15,000+ depending on the home’s size, number of bathrooms, pipe material, and how much wall access is needed. A small 1-bath house with easy access sits at the low end; a large two-story home with 3+ baths and slab construction sits at the top.

What Drives the Price
Pipe material. PEX is the most affordable and the most common choice today — flexible, quiet, and resistant to the mineral buildup that kills copper in our hard SoCal water. Copper costs more in both material and labor but some homeowners still prefer it.
Home size and bathroom count. Every fixture adds piping, valves, and labor hours. A 3-bath home is genuinely about twice the job of a 1-bath home.
Access. Single-story homes with attic access repipe faster and cheaper. Two-story homes and homes where lines run under the slab take more drywall openings and more patching.
Drywall repair. Ask whether patching and texture-matching are included — with Delta, they are, so you’re not hunting for a drywall contractor afterward.
Signs Your Home Needs a Repipe (Not Another Patch)
Repeated pinhole leaks in copper, rusty or yellow water from galvanized pipes, dropping water pressure throughout the house, or a slab leak diagnosis are the classic signs. If you’re calling a plumber for the second or third leak in a year, you’re already paying for a repipe — one leak at a time, plus the water damage. Our leak detection service can confirm what’s happening before you commit.
What the Job Looks Like
A typical repipe takes 2 to 5 days. Water stays on each night, we protect floors and furniture, replace every hot and cold line, install new valves and supply lines, pass city inspection, then patch and texture the walls. Details on our whole house repiping page.
