The cost to install or replace plumbing in a residential home ranges from $358 and $1,994. If you have a small leak or only need to replace a portion of your piping, you may pay as little as $360 for repairs. However, if your entire home needs new piping, you'll usually pay about $7,500, but it can cost up to $15,000 if you have a large home or complex project.

Install or Replace Plumbing Prices

The cost of materials plays a large part in the overall cost of installing or replacing plumbing. The three primary types of pipe you'll choose from include copper, PEX, and CPVC, and pricing is influenced by the diameter of the piping you need and how much of it.

Copper Pipe

Copper piping is a popular choice from whole-house plumbing because it has a long history of durability. For material alone, copper pipe costs $2 to $8 per linear foot.

You'll notice that cooper is much more expensive than plastic alternatives, but it offers a wide range of benefits.

Because it has decades of verifiable durability, copper piping is accepted by building codes across the country. It's so strong that it often survives natural disasters that may level a home.

It's also naturally resistant to bacteria and won't break down with UV exposure. As with all types of pipe, it can corrode and eventually burst, but you can expect copper to last 50 to 100 years.

CPVC Pipe

In use since the 1960s, CPVC is the most common plumbing material found in modern construction. Priced much lower than copper, it costs $0.50 to $1 per linear foot.

Like copper, CPVC is rigid and requires joints to make angles, but it offers stronger connections at these joints than copper. CPVC has a lower temperature limit than copper, but it can withstand higher temperatures than PEX.

Despite a long history of use, CPVC does eventually leak and may ultimately burst, though this is more often to happen with low-quality materials and faulty installation. When a plumber correctly installs high-quality CPVC, it typically lasts 50 to 70 years.

PEX Pipe

Made of a highly versatile plastic, PEX piping costs $0.40 to $2 per linear foot. It costs much less than copper piping and about the same as CPVC, but the tubing material is often favored for its physical flexibility.

PEX doesn't corrode like copper, and it resists the damaging effects of chlorine and the buildup of scale. Another big benefit is that plumbers can couple it with other material types. This means that, depending on your home's needs, a plumber may use PEX and another type of pipe like CPVC, to complete the job. While PEX can eventually burst with age, you can expect a lifespan of 80 to 100 years.

Install or Replace Plumbing Installation Cost

The cost of hiring a plumber is the other part of the equation when it comes to determining how much you'll pay to install or replace plumbing.

Inspection

If you're unsure if your home actually requires pipe replacement or you're unclear on the extent of possible pipe damage, it's a good idea to reach out to a plumber for advice before committing to whole-house replumbing.

Many plumbers offer a thorough inspection service where they go through all the plumbing in your home (which could amount to hundreds of feet) to gauge its condition and identify trouble areas. This inspection can tell you whether you need to replace all the plumbing, replace some of the plumbing, or take no action because there are no issues.

This inspection can run $250 to $1,200, with an average of $700, but it can save you thousands of dollars in unnecessary work if it finds you only need a minor repair or no work at all.

Replacing Piping

A plumber typically charges $45 to $480 per hour, with the average being about $330 per hour.

However, when providing a quote for the installation or replacement of piping, a plumber will generally offer a per-project bid rather than bill you by the hour. Assuming you have a standard-sized home with two bathrooms, a plumber will generally take about 28 hours for the replumbing project.

"As a licensed plumber with close to two decades working on residential projects, I would advise homeowners to exercise caution whenever hiring a plumber or any tradesman who wants to do every project on a time plus material basis rather than providing an upfront quote for the work,” says Jeff Botelho, an Expert Review Board member and licensed plumber. “A plumber's reluctance to commit to a quote is often an indication of a lack of confidence in themselves to complete the work on time and within a budget. Some jobs have too many unknown factors and will have to be done on time and materials, but they're few and far between."

This translates to total labor charges of $1,260 to $13,440, with the average being $9,240. A plumber's labor charges generally include demolition; that is, cutting through ceilings and walls to access hidden piping, if necessary, and removing your old piping. It does not cover the cost of ceiling and wall repairs after the pipe installation.

Assuming your plumber has to cut through the ceiling or drywall, you'll need to hire a handyperson or drywall expert to make repairs. Ceiling repair costs generally run $45 to $90 per square foot, while the cost to repair drywall is $50 to $75 per square foot.

Install or Replace Plumbing Cost by Type

When it comes to replumbing a home, you'll have the choice between copper, CPVC, and Pex piping. The cheapest material typically costs $0.40 per linear foot, while the most expensive may cost $8 per linear foot.

MaterialMaterial Cost per Linear Foot
Copper$2 – $8
CPVC$0.50 – $1
Pex$0.40 – $2

Install or Replace Plumbing Installation Cost by Linear Foot

Assuming your plumber charges $1 to $2 per linear foot in labor charges, the following shows what you might pay for plumbing projects requiring 500 or 1,500 linear feet of piping.

MaterialMaterial and Labor per Linear FootMaterial and Labor for 500-Linear-Foot ProjectMaterial and Labor per 1,500-Linear-Foot Project

CPVC$1.50 – $3$750 – $1,500$2,250 – $4,500
Pex$1.40 – $4$700 – $2,000$2,100 – $6,000

Install or Replace Plumbing Cost Factors

There are many factors that affect the cost to install or replace plumbing in your home. The biggest considerations are the size of your home, how many plumbing fixtures you have, the location of your existing pipes, and the cost of materials.

Size of the Home

Single-story homes generally cost less to repipe than two-story homes because the latter require more material to reach bathrooms and other plumbing fixtures on the upper floor.

Number of Plumbing Fixtures

Each fixture or appliance in your home that requires plumbing contributes to the overall cost of installing new pipe. Plumbing fixtures include sinks, toilets, showers and tubs, water heaters, and washing machines. The more fixtures you have, the more you'll pay.

Location of the Pipes

The location of your plumbing pipes affects the total cost of the project due to access issues. Pipes located behind drywall are easy to access, but pipes in crawl spaces or under concrete are harder to work on.

Cost of Materials

The type of piping you choose and the diameter of the piping you require have a direct effect on materials costs. Piping made of copper costs more than CPVC, while larger-diameter pipes simply require more raw material during manufacturing than smaller-diameter pipes.

DIY vs. Hire a Plumbing Pro

Plumbing is a job that you need to take very seriously. Having access to water and safe waste elimination is vital. While you may think that locating existing pipes, removing them, and replacing them is an arduous but ultimately simple task, you must take into account what might happen if you don't execute the process perfectly.

Leaking pipes is a common issue with improper installation, and the damage they cause can range from being an inconvenience to being catastrophic. In many cases, the cost of professional plumbing will be much less than the cost of repairing extensive water damage.

Also keep in mind that plumbers have liability insurance to protect you in case something goes wrong during the installation. You have homeowners insurance in the event something goes wrong after, but it will only cover repairs if the plumbing was completed by a professional.

In almost all cases, it's better to hire a local plumber than attempt to DIY.

"Whether or not you decide you want to attempt any plumbing projects in your home, the single most important thing I can recommend to every homeowner is to learn how to shut off their utilities in the case of an emergency,” says Botelho. “Nothing helps more in the case of a leaking waterline than knowing how to turn it off quickly to minimize damage to your home. Get familiar with where your main water shutoff is located and get comfortable with operating it. Learning where this valve is located can also help you determine if the main valve itself should be replaced."

FAQs

How do I know if my pipes need to be replaced?

Leaks and water damage are obvious signs that you're having problems with your pipes. But they won't necessarily reveal the extent of the issue. The best way to determine whether you're experiencing a small problem or a large one that requires full-house pipe replacement is to contact a professional plumber and request an inspection.

Should I hire a plumber or pipefitter to replace my home's piping?

The right professional for installing or replacing piping in your home is a plumber.

While plumbers and pipefitters have similar skill sets, they typically work in completely different industries. Plumbers work residential and commercial jobs that deal with plumbing for fresh water and waste. Pipefitters most often complete industrial work concerning hazardous materials.

How do I find a reliable plumber?

There are several steps you can take to vet a plumbing contractor. First, determine which are your local plumbing companies. Research them by reviewing their websites and reading customer reviews and testimonials.

Develop a short list of highly-rated plumbers, and then request quotes. During the home visit, ask questions about your project to gauge their experience, knowledge, and overall demeanor. When you have several quotes, compare them to decide which best suits your needs.
