How Much Does It Cost to Repipe a House?
Real 2026 pricing for whole-house repiping — PEX vs copper vs CPVC, what drives the cost, and how to avoid getting overcharged.
Last updated: June 2026
Important: Repiping requires a licensed plumber in all 50 states. DIY repiping is illegal, voids insurance, and risks catastrophic water damage. This guide helps you understand costs — always hire a professional.
The Short Answer
Whole-house repiping costs $4,000 to $15,000 in 2026, averaging $7,500 for a typical 2,000 sq ft, 2-bathroom home. PEX is the most popular choice ($4K-$10K) — it's cheaper, faster to install, and lasts 40-50 years. Copper costs 2x more ($8K-$18K) but lasts up to 100+ years. Wall repair adds $1,500-$3,000 on top. Most jobs take 1-3 days for PEX, 3-7 days for copper.

5 Factors That Change Your Repipe Cost
1. House size
Larger homes need more pipe, more labor, and more wall openings. A 3,000 sq ft home costs about 50% more than a 2,000 sq ft home.
2. Number of bathrooms
Each bathroom adds ~15% because of fixture density (sink, toilet, shower = 3-5 fixtures per bathroom). A 4-bath home costs 45% more than a 1-bath home.
3. Stories
Two-story homes cost 20-30% more — pipe must route between floors, requiring cutting into floor plates and more complex paths.
4. Accessibility
Finished basements and attics add cost because plumbers must cut through finished surfaces. Exposed joists (unfinished basement) are cheapest.
5. Local labor rates
Licensed plumber rates range from $75/hr (Southeast) to $150+/hr (Northeast/West Coast). Same job costs 2x more in San Francisco than Atlanta.
Red Flags When Hiring a Repipe Contractor
- Quote without inspection: A real repipe quote requires walking the house, checking access points, and counting fixtures. Phone quotes are unreliable.
- Pressure to use copper only: Some contractors push copper because the job pays more. PEX is the right choice for 80% of homes — get a second opinion.
- No warranty on work: Reputable repipe specialists offer 10-25 year warranties on materials and labor. No warranty = no accountability.
- Quote doesn't include permits: Repiping requires permits and inspection in all jurisdictions. If they say permits aren't needed, walk away.
- Price 30%+ below competitors: Usually means cutting corners on pipe quality, fittings, or wall repair.

Frequently Asked Questions
How much does it cost to repipe a whole house?
Whole-house repiping costs $4,000 to $15,000 in 2026, with the national average around $7,500 for a 2,000 sq ft home with 2 bathrooms. PEX repiping runs $4,000-$10,000. Copper repiping costs $8,000-$18,000. CPVC is mid-range at $5,000-$12,000. Add $1,500-$3,000 for wall repair (drywall + paint) after the plumbing work. Total project cost including wall restoration: $5,500-$18,000.
How much does it cost to repipe a house with PEX vs copper?
PEX repiping costs $4,000-$10,000 (average $6,500) vs copper at $8,000-$18,000 (average $12,500) for the same 2,000 sq ft home. PEX is 40-50% cheaper because it installs 2-3x faster — flexible tubing snakes through walls without cutting multiple access holes. Copper requires precise measurement and soldering at every joint. PEX lasts 40-50 years; copper lasts 50-100+. Most homeowners choose PEX unless they need copper for specific code requirements or acidic water conditions.
Does homeowners insurance cover repiping?
Generally no — insurance covers sudden water damage (burst pipe, leak) but not proactive replacement of aging pipes. However, if a pipe failure causes damage, the resulting water damage may be covered even though the pipe replacement itself isn't. Some policies offer a 'service line coverage' rider ($30-$50/year) that can contribute to repipe costs. If you're repiping due to an active leak, document everything and call your insurer before starting work.
How long does whole-house repiping take?
PEX repiping takes 1-3 days for a licensed crew. Copper takes 3-7 days (each joint requires soldering). The job includes: cutting access holes, removing old pipe, running new pipe, pressure testing, and temporary wall patching. Full wall restoration (drywall + texture + paint) adds another 2-5 days and is usually done by a separate contractor. Total project from start to finished walls: 1-2 weeks.
What are signs my house needs repiping?
Common warning signs: (1) frequent leaks (more than 1 per year), (2) discolored water (brown/yellow = corroding pipes), (3) low water pressure throughout the house, (4) pipes over 40 years old (especially galvanized steel), (5) polybutylene pipes (grey plastic, used 1978-1995 — known high failure rate), (6) visible corrosion or mineral buildup on exposed pipes. Homes with polybutylene should repipe proactively before failure causes water damage.
Can I live in my house during repiping?
Yes, but it's disruptive. Water is typically shut off for 4-8 hours per day during active work. The plumbers will restore water each evening so you can shower and cook. Expect noise, dust, and holes in walls. Most families stay home for PEX repipes (1-2 days disruption). For copper repipes (3-7 days), many families stay elsewhere. Plan for: portable toilet if all bathrooms are affected, paper plates to reduce dishwashing, and a hotel for the worst 1-2 days.
