The short answer
At Barrett Plumbing, whole-home repipes start at $4,950. The final price depends mostly on the size of the house, how many bathrooms and fixtures it has, how easy it is to reach the pipes, and whether you choose PEX or copper. We give you a fixed, upfront price after an in-home assessment, before any work starts.
What a repipe includes
A whole-home repipe replaces the water supply lines in your house — the pipes that carry hot and cold water to every fixture. It does not replace your drain lines.
- New water lines in PEX or copper to every fixture
- New shut-off valves
- The permit and inspection
- Pressure testing before walls are closed
- Coordinating wall access and patching
- Cleanup when we're done
What changes the price
Two houses with the same square footage can have very different repipe costs. These are the biggest factors:
- Number of bathrooms, kitchens, and fixtures — more fixtures means more pipe and more connections.
- Access — an open basement or crawl space makes the work faster. Finished basements and multiple stories take more work.
- Material — PEX is flexible and usually costs less to install. Copper costs more but some homeowners prefer it.
- Wall openings and patching — the less we have to open, the lower the cost.
- Extras — adding a main shut-off valve, new hose bibs, or fixture upgrades at the same time.
Signs your home needs a repipe
Repiping is a big decision, and we won't recommend it unless the pipe is actually wearing out. These are the common signs:
- Pinhole leaks that keep coming back in different spots
- Low water pressure across the whole house
- Rusty or discolored water, especially from hot taps
- Galvanized steel pipe (dull gray, with threaded fittings)
- Polybutylene pipe (usually gray plastic), which was used in some homes built roughly from the late 1970s to the mid-1990s
Is it cheaper to fix leaks one at a time?
For a single leak in otherwise healthy pipe, yes. But when the pipe is corroding throughout the house, each repair just moves the problem to the next weak spot. Add up a few leak repairs plus water damage, and a repipe often costs less over time — and it ends the leaks for good.
How long does it take?
Most repipes are done in a few days, depending on the size of the house and how easy it is to reach the pipes. We give you a clear schedule before we start.
