How Much Does It Cost To Repipe A House In 2022?

Kenneth Wilson

When your old plumbing system gets beyond saving with minor pipe repairs, or you already see visible signs of corrosion or rusting– that's the time to consider repiping your entire home.

The cost to repipe a standard 2 to 3 bedroom house can run from $1,725 to $17,000. It translates to an average price of $5 per square foot for new construction. A more definite average cost to repipe a house is $8,625, regardless of whether you're going with copper, PEX, or CPVC pipes.

Plumbing issues are inevitable for every homeowner, but we can't stress this enough– the sooner you do a whole-house repiping, the better. Corroded water pipes notoriously cause the pressure to drop. Hence, you might deal with frequent leaks that will only increase your water bills, rusty-tasting water, or burst pipes eventually.

Doing so will save you from the stress of residential piping network damage. In the long run, this may also cost you up to thousands of dollars in repairs.

Before you search for "local piping experts" or "repiping specialists near me," let's discuss the essential cost factors of your home repiping project. 

Factors Affecting Home Repiping Costs

Keep in mind that the cost to repipe house will depend on various factors, including the size and stories of the house, plumber labor costs, pipe type, and plumbing materials. Some properties may need to secure building permits for a repiping project, which you will also need to factor in the total project costs.

Here are some defining factors to keep into careful consideration as you set the proper budget for house repiping costs:

Number of Plumbing Fixtures

Simply put, the more fixtures you have– the more expensive costs you'll end up paying for a whole-house repiping project. It is primarily due to the increase in needed materials and time spent for installation work.

Fixtures are generally connected to the plumbing system, as they drain and deliver water in different areas of the home. Note that plumbing fixtures in your home could refer to the bathroom, dishwasher, faucets, shower, toilet, water heater, washing machine, and the like. Your plumber will need to separately replace the secondary drain as well as incoming lines for every fixture. (Related: Mandatory Fixes After A Home Inspection)

Access to Every Fixture

More than just the number of total fixtures in your home, if these are located in high, difficult-to-reach areas– you will need to pay your contractor more. Expect that it will take them longer to complete the job.

If your plumber can only access parts of the plumbing system through the crawlspace, closet, or slab foundation, this will also increase the total average cost to repipe a house. It will need additional effort, time, and expertise due to the limited space. 

Material Type

As you repipe your entire house, one crucial decision you’ll face is picking the type of piping material. Typically, you have three primary options in copper, PEX, and CPVC pipes. Each one has its own set of pros and cons. Your plumber can recommend a good material based on their preference or experience with previous clients.

It's best to understand the three different types of pipe to make an informed decision. Refer to the table below for a quick overview:

Piping Material

Average Cost

Remarkable Features

Copper Pipes

$9,200 - $23,000

Environment-friendly, crack resistant, expensive piping material

PEX (Cross-linked polyethylene) Pipes

$4,600 - $6,900

A durable and flexible plastic that’s easy to install

CPVC (Chlorinated polyvinyl chloride) Pipes


Rigid plastic that may be brittle in the long run, withstands hot water temperatures

  • Copper Pipes - Copper pipes are a common choice in the industry. In fact, these pipes are considered the oldest piping system today. A copper repiping project will easily cost you $9,200 to $23,000.  Several plumbers prefer copper pipes as it has been one reliable material over the years.  If you're wondering about its life expectancy, copper pipes can last you up to 75 to 100 years. Yes, you've read that right; it may last you a century at most.   However, the piping industry developed a recent trend of using alternative materials such as PEX and CPVC.   Copper pipes develop an increased risk of corrosion in the long run. These pipes also need meticulous maintenance and proper care.  When overlooked, pipes made of copper may leave blue-greenish stains in your plumbing fixtures. It may also infiltrate your home water supply or cause leaks in the plumbing system. 
  • PEX (Cross-linked Polyethylene) Pipes - PEX pipes are one of the newest materials on the market. It costs around $4,600 to $6,900.  What makes it a crowd-favorite choice? Well, it is flexible, easy to install, and versatile.  It's no wonder many builders prefer PEX pipes for modern homes and new construction projects.   Given that PEX material is relatively new, how long a PEX plumbing system typically lasts.  Another advantage of PEX pipes is that they can last you more than a century. That's longer than the average lifespan of copper pipes.  Once they are installed in place, you won't need to replace the pipes any time soon. Probably not once in your lifetime.  PEX material is also flexible; it can quickly contract or expand when exposed to freezing temperatures. It reduces the occurrence of burst pipes.  
  • CPVC (Chlorinated Polyvinyl Chloride) Pipes - Pipes made of CPVC material are another common choice in current remodeling projects. On average, this is priced at $8,625.  It has gained more popularity in recent years, given its easy installation and suitability for existing structures.   Although CPVC pipes do not last longer than copper pipes, you can count on them to give you 50 years of reliable plumbing. 

As the total diameter of your repiping project increases, the same applies to your preferred piping material. In some cases, you may also need to pay extra costs to your plumbing company to remove older pipes.

If you want to save money, you may keep the unused steel pipes just behind the walls. 

Home Size and Number of Stories

The bigger your house is, the more expensive the cost of whole-house repiping will be. You will need more materials, time, and extensive labor to complete the new plumbing system installation. 

In contrast, a smaller home will only require fewer materials and less installation labor. It will have cheaper project costs. Repiping a multi-story home will cost you more since you will have to demolish walls for vertical pipe replacement.

In some cases, repiping a house may need to drill around 8 to 20 holes in your walls and ceiling.  

Labor Costs

A local contractor will usually conduct an on-site assessment before giving you a cost estimate for whole-house repiping. With that said, labor costs may vary depending on a company's overhead costs.

Once you have chosen a contractor, it's essential to secure a written contract with all project details. It will give you complete transparency on where your expenses will go.

Pro tip: Prioritize insured contractors with solid ratings on the Better Business Bureau (BBB). You may also do a quick online search to browse online reviews from previous clients. 


Major plumbing renovation projects will need inspections and permits. The local permit fees may vary per state, but expect to spend $80 to $460.

After an inspection, chances are your plumbing system may require several upgrades to abide by code. Note that this may only increase the cost to repipe house.

Fortunately, most plumbing contractors will include the necessary permit fees in their initial bid. 

Plumbing Upgrades

You can also consider some upgrades and other plumbing-related renovations while having your residence repiped. Think of it as hitting two birds with one stone– you’ll end up saving money.  

  • Tankless Water Heater - Adding a tankless water heater will give you hot water at your convenience. Let's say you want to relax and soak in hot waters at the end of the long day. You can quickly achieve that well-deserved pamper time with this addition!   These heaters have a longer lifespan compared to standard storage-tank water heaters. Not to mention, they also take up less space than regular units. 
  • Low-flow Fixtures - If you want to take on a more environment-friendly approach, you may also choose to install low-flow fixtures during your repiping project.  Newer showerheads, faucets, and toilet models will use less water. As a result, you will pay lower water bills and save thousands of gallons of water in a year.  It is also one good way to increase the value of your residence. Now is the right time to consider being a conservationist in your way. 

What is the Most Cost-effective Choice for Repiping?

If you're working with a limited budget for a whole-house repiping project, you may benefit from PEX piping material. The cost to repipe house with pex is around $4,600 to $6,900.

It is less expensive than other piping material choices due to its lower labor and material costs. With that said, PEX pipes offer you a substantial cost-saving opportunity without necessarily sacrificing quality.

This flexible plastic hose can be easily twisted into the walls, creating minimal to no visible signs of damage. The flexibility of PEX material decreases the need for wall demolition on your end, which is a likely requirement if you choose rigid copper pipes. 

What are Some Signs that I Need to Repipe my House?

A complete house repipe is a significant investment. You might want to consider it as your next home project, given how it’s worth the effort and money. Replacing old pipes is highly unavoidable in most cases.

We have listed down some of the reasons why you might need to repipe your house: 

  • If you are constantly paying for repairs and plumbing work, installing a new pipe network can help you solve these lingering issues. Doing so saves you a lot of possible repair costs. 
  • Your house contains lead pipes. Pipes made of lead were only a concern in ancient homes centuries ago. However, there are still houses today with lead pipes which may present some serious health risks to homeowners. 
  • Your house might have galvanized steel pipes. Despite being a staple piping material before World War II, galvanized steel pipes can deteriorate after a certain number of years. Sediments caused by corrosion can end up in your tap or drinking water. 
  • House remodeling. If you plan to install a new bathroom or work on another plumbing fixture, consider having the house repiped simultaneously. It can help you save time and money. 

How Long Does Repiping A House Take?

Repiping an entire house may take a few days to one week to complete. Smaller homes will only take as quickly as two days, while large residences may take longer (especially those with multiple bathrooms).

Fortunately, you can still use your plumbing system throughout the repiping project. Your plumber will typically build a new plumbing network aside from the existing pipes. Once the change is made from the old system to the newly-built one, that may be the only time you will be without water. 

Checklist in Hiring a Local Plumber for Whole House Repiping

A residential repiping project is a critical task. Going the DIY route is out of the picture. Instead, you will need to focus on the most qualified local plumbers to carry out the job.

You wouldn't want to waste paying someone for their so-so service, who does the installation work haphazardly. It will only cost you more money on costly repairs in the long run.

Accordingly, here are some crucial considerations in hiring a plumbing company:  

  • Plumbers with license and insurance
  • With quality references and online testimonials
  • Active in the plumbing business for more than three years
  • Offers a full breakdown of labor and material costs, as well as any additional expenses (permits, on-site inspections)
  • Provides a guarantee or warranty after completing the repiping project

Entire home repiping sounds like a complicated job, but there's no need to be intimidated. As long as you take the time to understand the work involved, your local plumbing company or repipe specialist can get the job done correctly, quickly, and safely.

Repiping is one significant financial investment, but you will undoubtedly benefit from paying for a reliable plumbing network that you can use for a lifetime (Not an exaggeration, by the way). If you think it's time to change your old, worn-out pipes, consider a repiping project and get in touch with a reputable specialist today!
