//Quick answer
- The repipe signal is a pattern, not a single leak.
- Price is driven mostly by the number of bathrooms.
- PEX and copper are the two standard materials; both have trade-offs.
- Permitted, inspected work, with financing up to 10 years.
01Definition
What is a repipe?
Replacing the water supply piping throughout the house with new pipe, run to every fixture, with the old lines abandoned or removed. It is the fix for piping that is failing everywhere at once rather than in one place.
What are the signs?
Pinhole leaks in copper that keep appearing in different places. Galvanized steel lines that have rusted inside until flow is a trickle. Rusty, brown or metallic-tasting water from the hot and cold taps. Pressure that falls off when a second fixture runs. And a slab leak history that has reached its second or third repair.
02When it applies
When is a repair still the right answer?
A single leak in pipe that looks healthy around the repair. A pressure problem that turns out to be the regulator, not the piping. A discolored-water problem that is the water heater, not the lines. The technician's job is to say which one you have, including when the answer is that you do not need a repipe yet.
What decides the price?
Mostly the number of bathrooms, because each one adds fixtures and pipe runs; that is the primary driver across the $18,000 to $30,000 band. Foundation type, access and finishes matter too, and a repipe is permitted work with the fee separate.
03What goes wrong
What does patching a failing system cost over time?
Each pinhole repair is small on its own. Together, with the drywall, the flooring and the water damage between them, they add up to a repipe paid for in pieces with nothing to show for it. The point of the published range is to make that comparison possible before the third leak.

Common questions
$18,000 to $30,000, depending on the number of bathrooms.
Yes. A whole-house repipe is permitted and inspected work. Done-Rite pulls the permit.
Both are used for repipes and each has trade-offs. Done-Rite explains them for your house, with no pressure either way.
