How To Use This Guide
Start with the benchmark context, then compare your quote wording and scope against the checklist before you respond.
Whole-house repiping is a major project - and one of the most difficult home improvement quotes to evaluate. The range is wide, scope descriptions vary enormously between contractors, and the materials chosen (copper vs. PEX vs. CPVC) significantly change the cost. This guide gives you the benchmarks and the checklist to evaluate any repipe quote.
Typical cost ranges
National reference ranges. Actual pricing still depends on region, scope, equipment, and labor conditions.
| Job type | Low | High | Notes |
|---|---|---|---|
| PEX repipe - 1,000–1,500 sq ft home | $3,500 | $6,500 | PEX is typically the most economical option. |
| PEX repipe - 1,500–2,500 sq ft home | $5,000 | $9,000 | Cost scales with home size and fixture count. |
| PEX repipe - 2,500+ sq ft home | $7,000 | $15,000 | Large homes with many fixtures and bathroom count. |
| Copper repipe - 1,500 sq ft home | $6,000 | $12,000 | Copper material costs are significantly higher than PEX. |
| Drywall patching (if not included) | $500 | $2,500 | Always confirm whether patching is included or excluded. |
| Permit and inspection | $150 | $500 | Required for repipe in virtually all jurisdictions. |
What drives whole-house repipe pricing
- >Home size and fixture count: more bathrooms, more piping, higher cost
- >Pipe material: PEX is the most cost-effective; copper is 40–70% more expensive
- >Accessibility: slab-on-grade homes are more difficult than homes with crawl spaces
- >Number of floors: multi-story homes require more pipe and more complex routing
- >Drywall and flooring access: how many holes must be cut and patched
- >Regional labor market: plumbing labor rates vary significantly by location
- >Water pressure and valve replacements included vs. excluded
- >Hot water distribution upgrade decisions (loop system, recirculation pump)
What a complete repipe estimate should include
- OKMaterial specified: PEX, PEX-A, copper, or CPVC - with brand and gauge

- OKMain shut-off valve replacement or inspection included
- OKDrywall patching: clearly included or clearly excluded in writing
- OKPermit and inspection fees included
- OKWater heater reconnection included
- OKPressure test and final inspection process

Red flags in repipe estimates
- !Patching excluded from the quote but not clearly stated - this is the most common repipe surprise charge
- !Material type not specified - PEX-A and PEX-B are meaningfully different in quality and flexibility
- !Permit not included on a job that always requires one
- !No fixture or bathroom count listed - no way to compare quotes with different scopes
- !Quote skips a site assessment and gives a price without seeing the home
- !Very low bid that excludes drywall, valves, and permit - confirm full scope before comparing price
- !No written labor warranty on a $5,000–$15,000 project

Frequently asked questions
How much does a whole-house repipe cost?v
A full PEX repipe for a 1,500 sq ft home typically costs $5,000–$9,000 including labor, materials, and permit. Copper repiping runs $6,000–$12,000 or more for the same size home. Larger homes (2,500+ sq ft) with many fixtures can run $10,000–$20,000 depending on material and complexity.
How long does a whole-house repipe take?v
Most whole-house repipes for a single-family home take 2–5 days. Complex installs in slab-on-grade homes or multi-story houses can take longer. Contractors can typically restore running water at the end of each day.
Is PEX or copper better for repiping?v
PEX is flexible, freeze-resistant, easier to install, and significantly cheaper than copper. It is the material of choice for most repipe contractors today. Copper has a very long proven track record and some local codes or water chemistry conditions may favor it. Ask your contractor specifically about the tradeoffs for your home and local water supply.
Does a whole-house repipe include drywall patching?v
This varies significantly by contractor. Some include patching in the base price; others specifically exclude it. Always confirm in writing whether drywall and flooring access and patching are included. An excluded patching scope can add $500–$2,500 to the final cost.
Do I need to turn off the water during a repipe?v
Yes - the water supply to the home will be shut off during active work. Most contractors restore running water at the end of each working day so the home remains habitable. Confirm this with your contractor before the job starts.
