Key Factors That Affect Repiping Cost

The national average cost to repipe a house ranges from $4,000 to $15,000. Several variables determine where your project falls in that range.

House Size

More square footage means more linear feet of pipe, directly increasing material and labor costs.

Number of Floors

Multi-story homes need vertical pipe runs and complex routing, increasing costs by 40% for two floors and 70% for three.

Bathrooms & Fixtures

Each additional bathroom adds $1,000 to $2,000 in extra piping, fittings, and labor.

Foundation Type

Slab foundations require tunneling or rerouting through walls and attics, adding $2,000 to $5,000.

Pipe Material

Copper costs roughly two to four times more than PEX or CPVC per linear foot installed.

Location & Labor Rates

Plumbing labor rates vary significantly by region. Urban areas and high-cost states tend to be more expensive.

Frequently Asked Questions

Common questions about house repiping costs answered.

For a 1,500 square foot single-story home with two bathrooms, expect to pay approximately $2,500 to $6,000 with PEX or $7,000 to $16,000 with copper. Add $2,000 to $5,000 if your home sits on a slab foundation. Use our calculator above for a personalized estimate.
PEX is the better value for most homeowners. It costs less, installs faster, and performs well in cold climates. Copper is the better choice if long-term durability and maximum resale value are your priorities, or if local building codes require it.
Yes. Whole-house repiping can increase home value by removing a major concern for buyers and home inspectors. Homes with outdated galvanized or polybutylene pipes may sell at a discount. Fresh copper or PEX plumbing is a strong selling point and can recoup 40% to 60% of the project cost at resale.
Most residential repiping projects take 2 to 5 days depending on the home size, number of fixtures, and accessibility. PEX repiping tends to be faster (2 to 3 days) because the material is flexible and requires fewer connections. Copper repiping typically takes 3 to 5 days because each joint must be soldered.
Standard homeowners insurance generally does not cover the cost of repiping as preventive maintenance. However, if a pipe bursts and causes water damage, the resulting damage repair may be covered. If your home has a history of leaks or your pipes are aging galvanized steel, some insurers may even require you to repipe before renewing your policy.
