National Baseline & Scope Drivers
Replacing all water supply lines in a home — typically galvanized steel or polybutylene with copper or PEX. National planning range for this job sits between $4,000 and $18,000.
Key Price Drivers for Whole-House Repiping
- Existing pipe material: Galvanized steel is the most common trigger — it corrodes from the inside and restricts flow. Polybutylene (grey plastic) is a failure risk at fittings. Copper repipes cost more in material than PEX.
- PEX versus copper: PEX is faster to install and costs 30 to 50% less in material. Copper lasts longer and is preferred in areas with aggressive water chemistry. Some HOAs and historic districts require copper.
- Access — slab versus crawlspace: Homes on a slab require pipes run through walls and attic — more labor than a crawlspace home where lines run below the floor.
- Number of fixtures and stories: A single-story ranch repipes faster than a two-story colonial with fixtures on both levels and a finished basement.
- Wall repair after: Repiping through finished walls requires access holes that need drywall repair and painting. Some plumbers include basic patching; full restoration is often a separate contractor.
