If your home has failing galvanized, polybutylene, or old copper lines — or you’re fighting constant leaks — a whole-house repipe fixes the problem at the source. Here’s what to expect.
Typical repipe cost
A whole-house repipe usually runs $4,000 to $12,000+, driven mainly by home size, number of bathrooms, pipe material, and how accessible the existing plumbing is. A slab foundation or two-story home takes more labor than a simple single-story on a crawlspace.
What goes into the price
- Home size and number of fixtures and bathrooms
- Pipe material — PEX is common and cost-effective; copper costs more
- Slab vs. crawlspace access
- Drywall opening and patching
- Permits and inspection
Signs you may need a repipe
Repeat leaks, discolored water, low pressure throughout the house, and known bad pipe materials (polybutylene, old galvanized) are all reasons to consider a repipe instead of chasing one leak after another.
Frequently Asked Questions
How much does it cost to repipe a house?
Most whole-house repipes run $4,000 to $12,000+, depending on home size, pipe material, and whether the plumbing is under a slab or in a crawlspace.
How long does a repipe take?
Many homes can be repiped in a few days. The exact timeline depends on size, access, and how much drywall has to be opened and patched.
Is PEX or copper better for a repipe?
Both work well. PEX is flexible, resists freeze damage, and costs less to install; copper is time-tested and preferred by some homeowners. We\u2019ll walk you through the trade-offs.
