What Does Pipe Replacement Cost for a Single Pipe or Project?

Pipe Replacement Cost Factors

Not all pipe damage requires extensive replacement. Often, plumbers can replace just the affected section. Costs depend on the complexity of the job and the pipe material.

Pipe Type

Modern plumbing uses three main pipe types, each with different costs, pros, and cons.

Chlorinated Polyvinyl Chloride (CPVC)

CPVC costs $0.50 – $3 per linear foot and has been used since the 1960s as a rigid, affordable alternative to copper. It resists corrosion but is prone to leaks if installed improperly. When used correctly, it can last 50–75 years.

Polyethylene (PEX)

PEX costs $0.40 – $4 per linear foot and is a flexible, corrosion-resistant option suitable for both small repairs and full replacements. It’s ideal for in-floor heating and new construction but requires proper insulation to prevent freezing. Some systems may not be compatible with PEX, so professional guidance is recommended. Its lifespan ranges from 80 to 100 years.

Copper

Copper pipes, priced at $2 – $12 per linear foot, are durable, recyclable, and widely accepted by building codes. They resist UV and bacteria but can freeze and corrode over time. Despite the higher cost, copper remains a reliable choice, lasting between 50 and 100 years.

Pipe Length, Diameter & Installation Costs

Longer pipes increase material costs and may require additional repairs to walls, ceilings, or floors. Larger-diameter pipes, often used for drainage, also cost more but improve plumbing efficiency.

Fixture-Based Pricing
Plumbing costs vary by fixture, with repairs ranging from $70 to $1,700 depending on location and complexity. Common repair costs include:

• Kitchen sink: $150–$500

• Toilet pipe: $70–$700

• Water main line: $360–$1,700

• Bathroom sink: $200–$800

Labor Costs

Plumbers charge $45–$200 per hour, with simple replacements taking a few hours and complex jobs lasting days. Hard-to-reach pipes or extensive repairs increase labor costs.

Permits & Old Pipe Removal

Permits, required for major plumbing work, range from $50 to $500. Removing hazardous old pipes like lead or galvanized steel adds costs, especially if excavation is needed.

Water Line Replacement

Replacing a main water line involves excavation and costs $50–$250 per linear foot, with total expenses averaging $1,800.

Inspections & Accessibility

A basic plumbing inspection costs around $150, while a full home check averages $200. Hard-to-access pipes, such as those behind walls or under floors, significantly raise costs, sometimes reaching $2,000.

Repairing Walls, Ceilings & Floors

After pipe replacement, repairing access points adds costs:

• Drywall repair: $50–$75/sq. ft.

• Ceiling repair: $45–$90/sq. ft.

• Floor repair: $2–$30/sq. ft.

• Interior painting: $2–$6/sq. ft.

Location-Based Costs

Labor and material costs vary by region. Urban areas tend to be more expensive, while rural locations may have higher costs due to limited access to services.

Rough-In Plumbing Cost for New Construction

Rough-in plumbing happens when you build or remodel a home. It’s the process of installing all the pipes in your walls before installing the final fixtures, like your sink or toilet. You’ll spend $4.50 to $5.25 per square foot, but the total cost depends on the number of appliances and piping they need.

Cost to Replumb a Home

So, what happens when you have a bigger job than replacing a single pipe? Sometimes, you may need (or want) to replumb a whole home—like if you’re doing a complete remodel, want to swap out aging galvanized or lead pipes, or your piping is over 50 years old.

The cost to repipe a house is between $1,500 and $15,000, and the average homeowner spends $7,500. You can expect to spend $0.40 to $8 per linear foot on the piping, depending on the type of pipe. Copper is on the higher end, and labor is an additional $1 to $4 per linear foot.

Though the overall cost depends on the size of your home, here are some common prices.
