How much does it cost to repipe a house?
Repiping a house typically costs $4,000–$15,000. A small single-story home repiped in PEX sits at the low end; a large or multi-story home in copper, or one with hard access and lots of drywall repair, pushes toward the top and beyond.
Ranges are typical planning guides — actual price varies by region, access, materials and your local pro. Always get a written quote.
| Scenario | Typical cost | Notes |
|---|---|---|
| Small home, PEX (1–2 bath) | $4,000–$7,500 | Most affordable path |
| 3-bed / 2-bath home, PEX | $6,000–$10,000 | Most common job |
| Copper repipe | $9,000–$18,000+ | Material + labor premium |
| Drywall repair & repaint | +$1,000–$3,500 | Sometimes quoted separately |
What affects the price
PEX vs copper
PEX is flexible, fished through walls with fewer cuts, and costs roughly half of copper installed. Copper lasts 50+ years and resists UV and rodents, but material and soldering labor cost far more.
Home size and fixture count
Price scales with bathrooms, kitchen, laundry and hose bibs — every fixture is a run back to the manifold or main. Multi-story homes add complexity and wall openings.
Access and finish repair
Crawl-space and attic access keeps drywall cuts down. Slab homes and finished walls mean more openings, and patching and painting can be a separate $1,000–$3,500 line — check the quote.

How much does it cost to repipe a house?
Typically $4,000–$15,000 — around $6,000–$10,000 for an average home in PEX, and $9,000–$18,000+ in copper. Drywall repair may be extra.
When should a house be repiped?
Repeated pinhole leaks, rusty or discolored water, low pressure throughout the house, or original galvanized or polybutylene pipe are the classic signs it is time.
How long does a whole-house repipe take?
Most repipes take 2–5 days of plumbing work, and water is usually only off during the day. Drywall patching and painting afterwards adds another few days.
