What Does Repiping a House Cost and Involve?
Repiping a house replaces every water line, typically costing $1,500 to $15,000. PEX is cheaper than copper. Learn the signs you need a repipe, material choices, and how the process works.
The short answer
Repiping a house replaces all freshwater pipes with new PEX or copper, costing $1,500 to $15,000 (average $7,500) as of 2026. PEX is typically $6,000 to $12,000 cheaper than copper on a 2,000 sq ft home. The work takes 2 to 5 days and involves cutting into walls and ceilings.
Key takeaways
- Know the signs: Frequent leaks, rusty water, and low pressure often mean it is time for a repipe.
- Material choice drives cost: PEX is flexible and affordable; copper is durable but pricier.
- Get multiple quotes: Prices vary widely by region and home size, so compare licensed plumbers.
- Plan for disruption: You will lose water for days and need drywall repairs after the repipe.
If your home has old, corroded pipes or you are facing repeated leaks, a whole-house repipe might be the smartest move. It replaces every freshwater line, eliminating constant patch repairs. But repiping is a major project, with costs ranging from $1,500 to $15,000 depending on home size, material, and access. Understanding what is involved helps you budget and choose the right approach.
What exactly is a house repipe and when is it necessary?
A whole-house repipe replaces all the water supply pipes in your home. It is often needed when pipes are corroded, leaking frequently, or made of outdated materials like galvanized steel or polybutylene. Unlike a spot repair, which fixes one leak, a repipe gives you a fresh plumbing system that can last decades.
- Repiping addresses chronic issues: rusty water, low pressure, or multiple leaks.
- Common candidates: homes over 50 years old, especially those with galvanized pipes (lifespan 20-50 years).
- After a slab leak, a repipe may be the best long-term fix if your slab has multiple leaks or is difficult to access. Learn more about slab leak repair options.
- The process takes 2 to 5 days and requires cutting into walls and ceilings to access pipes.
- You will need to relocate during the work since water is shut off for extended periods.
How can I tell if my house needs a repipe instead of a repair?
Before calling a plumber, check for key warning signs that indicate systemic piping failure. While a single pinhole leak might only need a spot repair, several issues together often point to a full repipe.
- Rusty or discolored water: Brown or yellow water from multiple faucets suggests internal pipe corrosion.
- Frequent leaks: If you are calling a plumber more than once a year for leaks, your pipes may be failing.
- Low water pressure: Mineral buildup inside old pipes restricts flow, especially in galvanized steel.
- Visible pipe condition: Check exposed pipes in basements or crawl spaces for flaking, dimpling, or green spots (on copper).
- Use our Repipe Cost Calculator to estimate material and labor costs for your home size.

What does repiping a house cost in 2026?
The national average cost to repipe a house is about $7,500, with most homeowners paying between $1,500 and $15,000 as of 2026. Costs depend on pipe material, home size, and local labor rates. PEX is significantly cheaper than copper. Cost disclaimer: Costs vary by region, access, and contractor. Ranges on this page are compiled from the sources on our methodology page.

- Whole-home repipe total: $1,500 to $15,000, average $7,500 source.
- Per fixture average: about $1,200.
- PEX installed per linear foot: $0.40 to $2.00.
- Copper installed per linear foot: $2.00 to $8.00, making it $6,000 to $12,000 more on a 2,000 sq ft home.

What do homeowners often get wrong about repiping?
Many homeowners underestimate the scope of a repipe or assume insurance will cover it. Avoid these errors to prevent unexpected costs and delays.
- Assuming insurance covers it: Standard HO-3 policies typically cover water damage from sudden bursts, not gradual pipe deterioration. A repipe due to old age is rarely covered. Confirm with your carrier.
- Ignoring the need for drywall repair: Repiping requires cutting into walls and ceilings; patching and painting are separate costs not always included in plumbing quotes.
- Choosing the cheapest material without research: PEX is affordable but may not be allowed in some local codes. Always check local code requirements with your building department.
- Not getting multiple quotes: Prices can vary by thousands. Compare at least two licensed plumbers.
- Forgetting to budget for living expenses: You may need to stay elsewhere for 2 to 5 days while water is off.
- Use the Repair Method Finder to see if a full repipe is your best option.
Which pipe material is better: PEX or copper?
The biggest decision in a repipe is choosing between PEX and copper. PEX is flexible, freeze-resistant, and much cheaper, while copper is durable, widely accepted, and more expensive. For most homes, PEX offers the best balance of cost and performance.
- PEX (cross-linked polyethylene): Costs $0.40 to $2.00 per linear foot installed. Flexible, quiet, and resists scale buildup. However, it can be damaged by UV light and rodents.
- Copper: Costs $2.00 to $8.00 per linear foot installed. Longest lifespan (50+ years) and resists bacteria, but prone to pinhole leaks if water chemistry is aggressive.
- Cost difference: On a 2,000 sq ft home, copper repipes run $6,000 to $12,000 more than PEX.
- Resale value: Copper might appeal to buyers familiar with it, but PEX is now standard in most new construction.

Can I repipe my house myself, or should I hire a plumber?
Repiping a house is not a DIY project. It involves cutting into walls, soldering (for copper) or using specialized expansion tools (for PEX), and meeting local plumbing codes. Mistakes can lead to leaks, water damage, or failed inspections.
- DIY scope ends at assessment: You can check for signs like rusty water and low pressure, and use the Slab Leak Triage tool if you suspect a slab leak.
- Licensed plumber required: Repiping requires a permit in most areas, and a pro ensures proper sizing, connections, and pressure testing.
- Risks of DIY: Improperly installed PEX can kink; poorly soldered copper can leak. Water damage from a failed repipe can exceed the cost of hiring a pro.
- What you can do: Get multiple quotes, compare materials, and prepare your home (clear access areas, plan for relocation).

What are the signs you need your house repiped?
Frequent leaks, rusty or discolored water, low water pressure throughout the house, and visible corrosion on exposed pipes are key signs. If your home has galvanized pipes over 50 years old, a repipe is often necessary.
How long does repiping a house take?
Most whole-house repipes take 2 to 5 days, depending on home size, number of fixtures, and material. You will typically be without water during the work and may need to stay elsewhere.
Is PEX or copper better for repiping?
PEX is cheaper ($0.40-$2.00 per linear foot installed), faster to install, and freeze-resistant. Copper costs more ($2.00-$8.00) but lasts 50+ years and is accepted everywhere. For most homes, PEX offers the best value.
Does homeowners insurance cover repiping?
Standard HO-3 policies typically cover sudden water damage from burst pipes, not gradual deterioration or repiping due to old age. A repipe is usually considered maintenance. Confirm with your carrier.
Can I stay in my house during a repipe?
No, you will need to relocate during the project. Water is shut off for extended periods, and areas are inaccessible. Most homeowners stay with family or in a hotel for 2 to 5 days.
Should I repipe or keep repairing leaks?
If you have more than one leak per year, multiple leaks in a short time, or rusty water, a repipe is often more cost-effective long-term than repeated spot repairs. Use our Repair Method Finder to compare options.
Do I need a permit to repipe my house?
Yes, most municipalities require a plumbing permit for a whole-house repipe. A licensed plumber will pull the permit and ensure the work meets local code. Check with your building department.
Repiping a house replaces all freshwater pipes, typically costing $1,500 to $15,000 (average $7,500) as of 2026. Choosing between PEX and copper is the biggest cost driver. For a personalized estimate, try our Repipe Cost Calculator, and compare all your options on the repiping hub.
