Repiping Cost (2026 Pricing Guide)

Last updated: March 2026

By the Plumbing Price Guide Team

Repiping a house costs $4,000 to $15,000 in 2026 for a standard 2 to 3 bedroom home. Repiping is the process of replacing all the water supply pipes throughout the home with new pipe material, typically PEX, copper, or CPVC. The total price depends on the size of the home, the number of plumbing fixtures, the pipe material chosen, the accessibility of existing pipes, and whether drywall repair is included. Homeowners with aging galvanized steel, polybutylene, or lead pipes should understand the full cost picture before scheduling this work.

PEX repiping falls at the lower end of the range, typically $4,000 to $10,000 for a standard home. Copper repiping runs $6,000 to $15,000 or more. Most homeowners choose PEX today because it costs 30 to 40% less than copper, installs faster, and performs well in freezing climates. The prices above cover the plumbing work only. Drywall repair and painting after the repipe are almost always billed separately.

This guide breaks down repiping costs by home size, pipe material, and foundation type. It also covers how to tell when repiping is necessary, what the process involves, and how to save money on the project. For general plumbing pricing, see the plumbing cost guide. For smaller pipe issues, the pipe repair cost guide covers individual repairs.

How Much Does Repiping Cost by Home Size?

Home size is the single biggest factor in repiping cost. More square footage means more linear feet of pipe, more fittings, more labor hours, and more access holes in walls and ceilings. The number of bathrooms is a practical shorthand for the amount of plumbing in a home, since each bathroom adds a toilet, sink, and often a shower or tub.

These ranges assume standard accessibility. Homes with pipes running through finished walls, cathedral ceilings, or multi-story layouts will fall toward the higher end. Homes with open basements or crawl spaces where pipes are easily reached tend to cost less.

The number of fixtures also matters beyond bathroom count. A home with a kitchen, laundry room, wet bar, outdoor hose bibs, and a sprinkler connection has more pipe runs than a home of the same size without those features. Each additional fixture connection adds $200 to $500 to the project total.

How Much Does Repiping Cost by Pipe Material?

The replacement pipe material is the second largest cost factor. PEX, copper, and CPVC are the three materials used in residential repiping today. Each has different material costs, labor requirements, and performance characteristics.

PEX Repiping

PEX is the most popular repiping material in 2026. It accounts for roughly 60 to 70% of residential repipe projects. PEX is flexible, which means it can be snaked through walls with fewer access holes and fewer fittings than rigid pipe. This reduces both material and labor costs. PEX also resists freezing better than copper or CPVC because the tubing can expand slightly before cracking.

PEX comes in three types: PEX-A (most flexible, most expensive), PEX-B (good balance of cost and performance), and PEX-C (least flexible, least expensive). Most repipe contractors use PEX-A or PEX-B. The tubing is color-coded: red for hot water lines, blue for cold water lines, and white for either. PEX connects with crimp, clamp, or expansion fittings rather than soldering, which speeds up installation.

Copper Repiping

Copper is the traditional premium choice for residential plumbing. It has a proven track record of 70 to 100 years and remains the standard in some regions, particularly in the Northeast and parts of the West Coast. Copper is rigid, requires soldered joints, and costs more for both materials and labor compared to PEX.

Copper prices have risen significantly over the past decade due to global demand. The material cost alone for a whole-house repipe in copper can exceed $2,000 to $4,000, compared to $500 to $1,500 for PEX. Copper is also more labor-intensive to install because each joint must be soldered (sweated) by a skilled technician, and rigid pipe requires more precise cutting and fitting.

CPVC Repiping

CPVC is a rigid plastic pipe that handles hot and cold water. It costs slightly more than PEX but less than copper. CPVC uses solvent-cement joints (glued fittings), which are faster than soldering copper but slower than PEX connections. CPVC is approved for residential use in most areas, though some jurisdictions have restrictions.

The main drawback of CPVC is a shorter expected lifespan (25 to 40 years) compared to PEX or copper. CPVC can also become brittle over time, especially in areas with high chlorine content in the water supply. For most homeowners, PEX offers better long-term value unless local codes require CPVC.

What Is Included in a Repiping Quote?

Understanding what a repiping quote covers prevents surprises on the final bill. Most plumbing companies include the core plumbing work but exclude cosmetic restoration. Here is a breakdown of what is typically included and what is not.

Typically Included in a Repipe Quote

• Removal of old pipes. The plumber disconnects and removes accessible sections of the old piping. In some cases, old pipes behind walls are abandoned in place and the new pipes are run on a different path.
• Installation of new supply lines. All hot and cold water supply lines from the main shutoff to every fixture in the home are replaced.
• New shut-off valves. Individual shut-off valves at each fixture (sinks, toilets, water heater) are replaced with new quarter-turn ball valves.
• Pressure testing. The system is pressure tested after installation to confirm there are no leaks before the walls are closed up.
• Permit and inspection. Reputable companies include the cost of the plumbing permit and coordinate the required inspection.
• Basic access hole patching. The plumber covers the access holes cut into drywall with basic patches. This is functional, not cosmetic.

Typically NOT Included

• Finish drywall repair and painting. This is the most common exclusion. Budget $1,000 to $3,000 for a drywall contractor to tape, mud, texture, and paint all the access points after the repipe. Larger homes or homes with textured walls cost more.
• Drain line replacement. A standard repipe covers supply lines (incoming water) only. Drain and sewer lines are a separate project. If drain pipes also need replacement, expect an additional $2,000 to $8,000 or more.
• Fixture replacement. Faucets, toilets, and other fixtures are reconnected but not replaced unless specifically requested.
• Water heater replacement. The water heater is reconnected to the new piping but not replaced. If the water heater is aging, consider replacing it at the same time to save on a future service call.
• Hose bib replacement. Some quotes include outdoor hose bibs; others treat them as add-ons at $100 to $300 each.

Always ask for a written, itemized quote that specifies exactly what is and is not included. The plumbing quote checker can help homeowners evaluate whether a quote is reasonable for their area and project scope.

How to Know If Your Home Needs Repiping

Not every plumbing problem calls for a full repipe. Individual leaks, dripping faucets, and clogged drains are routine repairs. But certain patterns and conditions point toward system-wide pipe failure that makes a full repipe the smarter investment. Here are the signs that indicate repiping may be necessary.

• Frequent leaks in different locations. One leak is a repair. Two or three leaks in different parts of the house within a year or two suggest the entire system is deteriorating. Fixing individual leaks becomes a losing battle when the underlying pipe material is failing throughout.
• Rusty or discolored water. Brown, yellow, or orange-tinted water coming from the tap, particularly the hot water side, often indicates corroding galvanized steel pipes. Running the water for a few minutes may clear it temporarily, but the corrosion continues to worsen.
• Declining water pressure. Galvanized steel pipes corrode from the inside, gradually restricting water flow. If water pressure has noticeably decreased over the past several years, internal buildup is likely the cause. This problem cannot be fixed without replacing the pipes.
• Visible pipe corrosion. Green or blue-green staining on exposed copper pipes indicates corrosion at the joints. White, chalky buildup on galvanized pipes signals exterior deterioration. Flaking, pitting, or dimpling on any exposed pipe is cause for concern.
• Polybutylene pipes. If your home was built between 1978 and 1995 and has gray, flexible plastic pipes, those are likely polybutylene. This material has a well-documented history of failure due to a manufacturing defect. Most insurance companies will not cover water damage from polybutylene pipe failures. Use the pipe material identifier to check your home.
• Galvanized steel pipes. Common in homes built before the 1960s, galvanized steel pipes corrode internally over 40 to 60 years. Once corrosion begins restricting water flow, the only permanent solution is repiping.
• Lead pipes. Homes built before 1930 may have lead supply pipes, which pose a serious health hazard. Lead pipes should be replaced regardless of their physical condition.
• Home is over 50 years old and has never been repiped. Even copper pipes, which last 70 to 100 years, begin to show age after 50 years. A plumber can inspect exposed pipes and assess their remaining lifespan.
• Planning a major renovation. Opening up walls for a kitchen or bathroom remodel is the ideal time to repipe, since much of the access work is already done. Combining the projects can save $1,000 to $3,000 in drywall repair costs.

Pipe Material Problems by Era

The age of a home often reveals the type of pipes it contains, and certain pipe materials from specific eras have known problems. Understanding what is in the walls helps homeowners make informed decisions about whether to repipe, and how urgent the situation is.

Lead Pipes (Pre-1930)

Lead was used for water supply lines in some homes built before 1930, and lead service lines (the pipe connecting the home to the municipal water main) were installed as late as 1986 in some areas. Lead is a known neurotoxin, and there is no safe level of lead exposure. Homes with lead supply pipes should be repiped as a health priority, not just a plumbing concern.

Lead pipe replacement costs $4,000 to $12,000 depending on the scope. Some municipalities offer assistance programs to help cover the cost of replacing lead service lines. Check with the local water utility for available programs.

Galvanized Steel Pipes (1930s to 1960s)

Galvanized steel was the standard residential plumbing material from the 1930s through the early 1960s. These pipes are steel coated with a layer of zinc to prevent rust. Over time (typically 40 to 60 years), the zinc coating erodes, and the underlying steel corrodes from the inside out. This internal corrosion restricts water flow and introduces rust particles into the water supply. The galvanized pipe replacement guide for Indianapolis provides a regional cost example.

Galvanized pipes cannot be repaired or restored. Once corrosion has begun restricting flow, the only permanent fix is a full repipe. The galvanized-to-PEX or galvanized-to-copper repipe is one of the most common repiping scenarios in the United States.

Copper Pipes (1960s to Present)

Copper became the dominant residential plumbing material in the 1960s and remains in wide use today. Copper pipes last 70 to 100 years under normal conditions, making them the longest-lasting common pipe material. However, copper is not immune to problems.

Pinhole leaks in copper pipes are caused by aggressive water chemistry, particularly water with low pH (acidic) or high mineral content. Some regions experience higher rates of copper corrosion than others. Homes with copper pipes that are developing pinhole leaks in multiple locations may be candidates for repiping, even though the pipes are well within their expected lifespan.

Polybutylene Pipes (1978 to 1995)

Polybutylene (often abbreviated PB or referred to by the trade name Quest) is a gray, flexible plastic pipe used extensively in new construction and mobile homes from 1978 to 1995. An estimated 6 to 10 million homes in the United States were plumbed with polybutylene. The material was the subject of a major class-action lawsuit due to a manufacturing defect that causes the pipe to become brittle and crack, particularly at the fittings.

Polybutylene failures are unpredictable. A home may have polybutylene pipes for 30 years without a problem, then experience multiple catastrophic failures in a short period. Many insurance companies refuse to insure homes with polybutylene plumbing, or charge significantly higher premiums. Lenders may also require polybutylene replacement before approving a mortgage. For Atlanta-area homeowners, the polybutylene repipe cost guide for Atlanta covers local pricing.

CPVC Pipes (1980s to Present)

CPVC is a rigid plastic pipe that has been used for residential hot and cold water lines since the 1980s. While CPVC performs well in many applications, it can become brittle over time, especially in homes with high-chlorine water or pipes exposed to UV light in unconditioned spaces. CPVC that has become brittle will crack and leak, sometimes without warning.

Homes with CPVC pipes that are 25 to 30 years old should have the pipes inspected for signs of brittleness. If the pipes snap easily when bumped or feel rigid and chalky to the touch, repiping is advisable.

PEX Pipes (1990s to Present)

PEX is the current standard for residential plumbing. Early versions of PEX fittings (brass fittings with a zinc content, manufactured before 2010) experienced dezincification in areas with aggressive water chemistry, causing leaks at the connections. Modern PEX systems use improved fittings and have an excellent performance record. Homes with PEX installed after 2010 are unlikely to need repiping for 40 to 50 years or more.

Partial vs Whole House Repipe: How to Decide

A partial repipe replaces some of the pipes in the home while leaving others in place. This costs $1,000 to $4,000 depending on the scope. A partial repipe makes financial sense in certain situations, but it can also be a false economy if the remaining old pipes fail shortly after.

When a Partial Repipe Makes Sense

• Isolated problem area. If only one section of the home (such as a single bathroom or the kitchen) has developed leaks or corrosion, and the rest of the plumbing is in good condition with a different or newer pipe material, replacing just that section is reasonable.
• Mixed pipe materials. Some homes have been partially repiped in the past. If the kitchen and one bathroom already have PEX or copper, but the master bathroom still has galvanized steel, repiping only the remaining galvanized section makes sense.
• Budget constraints. If a full repipe is not financially feasible right now, a partial repipe of the most deteriorated section buys time. This is a stopgap, not a long-term solution, in homes where all pipes are the same problematic material.
• Renovation scope. If a remodel is opening up walls in one section of the home, repiping that section while the walls are open is cost-effective even if the rest of the plumbing is in acceptable condition.

When a Full Repipe Is the Better Choice

• Polybutylene throughout. Because polybutylene failures are unpredictable and the entire pipe system is at risk, a partial repipe leaves the homeowner exposed to future failures and potential water damage.
• Galvanized steel throughout. If all the supply lines are galvanized and the home is experiencing flow restriction or discolored water, the entire system is deteriorating and a partial fix is temporary.
• Lead pipes. Lead contamination affects every fixture connected to lead pipes. A partial replacement does not eliminate the health risk.
• Multiple leaks in different areas. If leaks have occurred in the kitchen, a bathroom, and the laundry room within a two-year period, the pipe material itself is failing. Replacing one section will not prevent the next failure in a different location.
• Planning to sell. A home with known polybutylene or galvanized pipes will face scrutiny during inspection. A full repipe resolves the issue cleanly and avoids negotiation delays during the sale process.

For single-line issues rather than whole-system problems, the water line replacement cost guide covers that specific scope of work.

What Does the Repiping Process Look Like?

A whole-house repipe is a significant project, but understanding what happens at each stage helps homeowners prepare. The process typically takes 2 to 5 days for a standard home, with drywall repair adding additional time afterward. Here is what to expect step by step.

Step 1: Inspection and Planning (Day Before or Day 1)

The plumber inspects the existing plumbing system, identifies the current pipe material and layout, and plans the routing for the new pipes. This includes determining how many access holes are needed, where the new pipe runs will go, and whether any fixtures need to be temporarily removed. The plumber also reviews the permit requirements and submits the application if not already done.

Step 2: Protecting the Home

Before cutting into walls, the crew lays down drop cloths, covers furniture and belongings near work areas, and sets up dust containment if needed. Some companies use plastic sheeting to isolate work areas from the rest of the home. Drywall cutting generates significant dust, so this step matters.

Step 3: Cutting Access Holes

The plumber cuts strategically placed openings in drywall, ceilings, or floors to access the existing pipes. An experienced repipe crew minimizes the number and size of access holes. In a typical 2-bathroom home, expect 10 to 20 access openings of various sizes.

Step 4: Installing New Pipes

New pipes are run from the main water supply through the walls and ceilings to each fixture. PEX can be snaked through wall cavities with fewer holes than rigid pipe. Copper requires more access points because it cannot bend around corners. Each fixture gets a new dedicated supply line (hot and cold) with a new shut-off valve.

Step 5: Connecting Fixtures

Each fixture (sink, toilet, shower, tub, dishwasher, washing machine, water heater, hose bibs) is connected to the new piping system. The plumber replaces all shut-off valves with modern quarter-turn ball valves, which are more reliable than the older gate valves found in many homes.

Step 6: Pressure Testing and Inspection

After all connections are made, the system is pressurized and tested for leaks. The plumber monitors pressure over a set period to confirm the integrity of every joint. Once the system passes the plumber's test, the municipal inspector visits to verify the work meets code. Water is not fully restored until the system passes inspection.

Step 7: Basic Patching and Cleanup

The plumber installs basic drywall patches over the access holes. These patches are functional, not cosmetic. The crew removes debris, vacuums the work area, and restores the home to a livable condition. Finish drywall taping, mudding, texturing, and painting are handled separately by a drywall contractor, unless the plumbing company offers that service as an add-on.

How Foundation Type Affects Repiping Cost

The home's foundation type has a direct impact on repiping cost because it determines how easily the plumber can access the pipes below the first floor. Water supply lines run horizontally through the lowest accessible space before branching up through walls to fixtures.

Slab foundation homes are the most expensive to repipe because the plumber cannot access the area below the first floor. In these homes, the new pipes are typically routed through the attic (common in southern states), through interior walls, or through a combination of both. Attic routing works well in warm climates but requires insulation to prevent freezing in colder regions.

For homeowners dealing with pipe problems related to their slab foundation, the pipe repair cost guide includes a section on slab leak repair, which is a different scope of work from repiping.

Regional Repiping Cost Variation

Repiping costs vary significantly by region due to differences in labor rates, cost of living, permit fees, and local building code requirements. The national average of $4,000 to $15,000 is a useful baseline, but actual costs in a specific area may be higher or lower. Plumber hourly rates vary from $75 to $150+ per hour depending on the market.

The Southeast and South Central regions tend to have lower repiping costs due to lower labor rates and a higher prevalence of slab foundations with attic routing, which is a well-established practice in those areas. The Northeast and West Coast have higher costs driven by higher plumber hourly rates and stricter permitting requirements.

For city-specific repiping pricing, see the local cost guides for Las Vegas, Raleigh, Atlanta (polybutylene), and Orlando (cast iron). These guides include local labor rates, common pipe materials in the area, and regional factors that affect pricing.

How to Save Money on Repiping

Repiping is a significant investment, but several strategies can reduce the total cost without compromising the quality of the work. Here are practical ways to keep the project affordable.

• Choose PEX over copper. PEX costs 30 to 40% less than copper for a whole-house repipe. The material is less expensive, and the labor is faster because PEX is flexible and uses push-fit or crimp connections instead of soldering. Unless local code requires copper or personal preference dictates it, PEX offers the best value.
• Get at least three quotes. Repiping quotes can vary by $2,000 to $5,000 or more for the same home. Three quotes provide a reliable range and help identify outliers. The guide to finding a good plumber covers how to evaluate contractors beyond price alone.
• Handle drywall repair yourself or hire separately. Plumbing companies that offer drywall repair typically subcontract the work and add a markup. Hiring a drywall contractor directly, or doing the patching yourself if you are comfortable with the work, can save $500 to $2,000.
• Schedule in the off-season. Plumbing companies are busiest during summer (outdoor plumbing season) and winter (frozen pipe emergencies). Scheduling a repipe in spring or fall may yield lower quotes and faster scheduling. Some companies offer off-season discounts.
• Ask about financing. Many plumbing companies offer financing for large projects like repiping. Some offer 0% interest for 12 to 18 months. While financing does not reduce the total cost, it makes the project accessible without depleting savings.
• Combine with other work. If the water heater is nearing end of life, replacing it during the repipe saves a future service call. If a bathroom or kitchen remodel is planned, scheduling the repipe to coincide with the renovation eliminates duplicate drywall work.
• Consider a partial repipe when appropriate. If only one section of the home has problematic pipes and the rest are in good condition, a partial repipe at $1,000 to $4,000 is a legitimate option. This is not advisable for homes with polybutylene or galvanized pipes throughout.

Use the plumbing cost calculator to estimate the repiping cost for a specific home size, material, and location before requesting quotes.

Permits and Inspections for Repiping

Repiping requires a plumbing permit in virtually every jurisdiction in the United States. The permit ensures the work is performed to code and inspected by a qualified authority. Homeowners should never hire a plumber who suggests skipping the permit to save money. Unpermitted work can create legal problems during a home sale and may void insurance coverage for water damage.

Permit Costs

Plumbing permit fees for a whole-house repipe range from $100 to $400 depending on the jurisdiction. Some municipalities charge a flat fee; others base the fee on the number of fixtures or the project value. The plumber typically handles the permit application as part of the project.

What the Inspector Checks

• Proper pipe material and sizing. The inspector verifies that the pipe material is code-approved and the pipe diameters are correct for the number of fixtures served.
• Support and securing. Pipes must be properly supported with hangers or straps at specified intervals to prevent sagging or movement.
• Pressure test. The inspector may require a pressure test to confirm no leaks exist in the new system.
• Proper connections. All connections to fixtures, the water heater, and the main supply must meet code specifications.
• Isolation valves. Modern code typically requires individual shut-off valves at each fixture.
• Expansion tank (if applicable). Homes with a closed plumbing system (a backflow preventer on the main line) may require a thermal expansion tank on the water heater.

Inspection Timing

The inspection typically happens after the new pipes are installed but before the walls are closed up. This is called a "rough-in" inspection. The inspector needs to see the pipes, connections, and supports before they are hidden behind drywall. If the plumber closes the walls before inspection, the inspector may require the walls to be opened again, adding significant cost.

Some jurisdictions also require a final inspection after the drywall is repaired and all fixtures are reconnected. Check with the local building department for the specific inspection requirements in the area.

Questions to Ask When Getting Repiping Quotes

Getting accurate, comparable quotes requires asking the right questions. Here is a checklist of essential questions for any plumber providing a repiping estimate.

• What pipe material do you recommend, and why? A reputable plumber should explain their recommendation and be willing to discuss alternatives. Be cautious of any contractor who pushes a specific material without explaining the reasoning.
• Is drywall repair included? Clarify whether the quote includes rough patches, finish drywall, painting, or none of the above. This is the most common source of misunderstanding in repiping quotes.
• Does the quote include the permit and inspection fees? Some quotes include permits; others list them as a separate line item. Know what you are comparing.
• How many days will the project take? A realistic timeline helps with planning. Be wary of estimates that seem unusually fast (cutting corners) or unusually long (inefficiency).
• Will I have water during the project? Most repipe crews can maintain partial water service during the project, shutting off water only when making specific connections. Some sections may be without water for a few hours at a time.
• Are you licensed and insured? Verify the plumber holds a valid plumbing license for the jurisdiction and carries both general liability and workers' compensation insurance.
• Do you offer a warranty on the work? Most repipe contractors offer a 1 to 5 year labor warranty in addition to the manufacturer's warranty on the pipe material (which can be 25 years or lifetime for PEX and copper).
• Will you handle the old pipes? Ask whether old pipes are removed or abandoned in place, and whether removal is included in the price. Copper pipes being removed have scrap value, which some plumbers keep as part of the deal.
• How will the new pipes be routed? Understanding the routing plan helps the homeowner anticipate where access holes will be cut and what the drywall repair scope will look like.
• What is your payment schedule? A reasonable payment structure might be 10 to 30% deposit, progress payments at milestones, and final payment upon completion and passed inspection. Avoid paying the full amount upfront.

Frequently Asked Questions

How much does it cost to repipe a house?

A whole house repipe costs $4,000 to $15,000 for a standard 2 to 3 bedroom home. PEX repiping costs $4,000 to $10,000. Copper repiping costs $6,000 to $15,000 or more. The price depends on home size, number of fixtures, pipe material chosen, and accessibility.

How long does repiping take?

A whole house repipe takes 2 to 5 days for a standard home. A small home with open access may take 2 days. A large home with pipes in finished walls may take a full week. Drywall repair adds additional time.

Is PEX or copper better for repiping?

PEX is the most popular choice today. It costs 30 to 40% less than copper, installs faster, and resists freezing better. Copper has a longer proven track record (70+ years). Both are excellent materials.

How do I know if my house needs repiping?

Signs include frequent leaks, rusty or discolored water, low water pressure that has worsened over time, visible pipe corrosion, polybutylene or galvanized steel pipes, or a home over 50 years old that has never been repiped.

Does repiping include drywall repair?

Most plumbing companies do NOT include drywall repair. The plumber patches major access holes, but finish drywall work and painting is typically hired separately. Budget $1,000 to $3,000 for drywall repair after a repipe.

Do I need a permit to repipe my house?

Yes. Repiping requires a plumbing permit in virtually all jurisdictions. Your plumber should handle the permit application. Fees are typically $100 to $400.

Can I repipe just part of my house?

Yes. A partial repipe ($1,000 to $4,000) makes sense if the problem is isolated. But if the home has polybutylene or galvanized pipes throughout, partial repiping is temporary. A full repipe is more cost-effective long-term.

What pipe materials are most problematic?

Polybutylene (gray plastic, 1978 to 1995) has a known manufacturing defect. Galvanized steel (pre-1970s) corrodes internally. Lead pipes (pre-1930) are a health hazard. All three warrant full replacement.

How can I save money on repiping?

Choose PEX over copper (saves 30 to 40%), get 3+ quotes, do your own drywall repair after, schedule in the off-season, and ask about financing options.

Does repiping increase home value?

A repipe does not significantly increase appraised value but prevents a sale from falling through during inspection. Homes with polybutylene, galvanized, or lead pipes often fail inspection or have lenders require remediation before closing.
