How Much Does It Cost to Repipe a House in 2025?

Cost Factors for Repiping a House

The cost of repiping a house can vary greatly depending on a few key factors, particularly the size of the home, the number of fixtures that need to be connected, the materials you choose, and the size of the pipes themselves.

Home Size

The larger your home, the more extensive the plumbing system, which means higher repiping costs. Larger repiping projects require more labor hours and more materials, driving the price ever higher. Installing new plumbing costs around $4.50 per square foot, and this table outlines the average cost of repiping homes of various sizes.

Number of Plumbing Fixtures

Another way to determine how much your repiping project will cost is by looking at how many plumbing fixtures (such as toilets, sinks, dishwashers, washers, and showers) will need to be connected. Of course, different features have different costs associated with them. For instance, installing plumbing for a toilet will cost less than the average water heater replacement cost. 

Generally speaking, though, rough-in plumbing for most fixtures will cost between $220 and $1,800 each. Naturally, the more fixtures you need to connect, the higher your project cost will be.

Pipe Material

Another key cost factor to consider is the price of various pipe materials. Your building code might mandate certain materials to be used. The most common pipe materials are:

• Copper: Typically used for supply lines, copper pipes cost about $3 per linear foot or $8 per linear foot for drain lines.

• PEX: A flexible plastic hose material with lower installation costs, at about $1.15 per linear foot.

• PVC: A common, inexpensive pipe material used for drain and waste pipes, costing between $2 and $4.50 per linear foot. 

• CPVC: A variant of PVC designed to withstand higher temperatures and used for supply lines, CPVC costs about $0.98 per linear foot.

Diameter of Supply and Drain Line

Another material factor is the diameter of the pipes you choose to install. Supply and drain lines with a larger diameter are capable of supporting higher water needs, which you might need if you’re repiping a large house with many fixtures. The cost to replace a drain pipe, for instance, will be higher if you need a 3-inch pipe versus a more common 2-inch pipe. 

Accessibility

The cost to hire a plumber will rise if any of your existing pipes are in difficult-to-reach places, such as pipes in crawl spaces, encased in concrete, or in an awkward spot between wall studs or floor joists. Expect your plumbing cost estimate to be higher if any of your existing pipes are difficult to access.

Additional Repiping Cost Factors

Beyond the more obvious repiping cost factors like home size and number of fixtures, you’ll need to make a few other key considerations, such as the cost of labor, inspections, permits, and disposal of old pipes.

Labor

Labor is the biggest factor in the price of repiping your house. You can expect to pay between $60 and $200 per hour to hire a local, professional plumber. That means the labor costs make up around 70% of the total price of a repiping project.

Inspection

Inspections are a necessary cost for all new construction, including for repiping projects. The exact costs of a plumbing inspection will vary depending on your location, so make sure you get an estimate before setting the final budget for this project.

Permits

Like inspections, permits are a vital part of getting a repiping project approved. Permit prices also vary greatly by region, but you can expect to pay somewhere between $50 and $500 to get the permits you need.

Disposal

Unless you’re piping a brand new home, you’ll need to pay to have your old pipes removed and disposed of. This cost will be reflected in your initial estimate, but you can expect it to add between $1,000 and $4,500 to your final bill. 

Repiping vs. Pipe Repair

With repiping being such a high-cost project, it’s important to know whether or not you really need to redo all of your plumbing. In many cases, you may be able to make some relatively inexpensive repairs to extend the life of your current piping system. However, if you’re facing any of the following problems, it might make more financial sense to repipe your home instead:

• Change in water color or taste: If your home’s water supply is discolored or if the taste of your water suddenly changes, it could be a sign of corrosion in your plumbing. In many cases, corroded pipes will need to be replaced entirely.

• Drops in water pressure: If you’re experiencing ongoing drops in your water pressure, it’s often a sign of issues with your supply lines. You may have to repipe your home or look into water main replacement costs.

• Back-ups: Are your sinks and tubs taking an extra long time to drain, even if the drain itself is clear? It could be a sign of issues with your drain or waste lines, which might need to be repiped.

• Leaks: Leaks (even small ones) can be a symptom of serious plumbing trouble, which can cause significant water damage to your home. If you notice leaking pipes, you’ll need to at least have the whole plumbing system inspected, if not replaced entirely.

• Aging pipes: Plumbing systems generally aren’t designed to last beyond 50 years. If your pipes are older than this, regular inspections are recommended to ensure there are no problems.

Does Repiping a House Increase Home Value?

Repiping a house doesn’t add home value in the same way that renovating a bathroom or remodeling a kitchen does. However, old or defective pipes are a major liability and will probably make any potential buyer think twice before making an offer, meaning you’ll have to lower your asking price. 

Because working pipes are an expectation and not a selling point, they don’t offer an ROI in the same way that other home improvements do. However, it’s well worth investing in new piping if your current plumbing isn’t likely to pass inspection.

Budgeting for Repiping a House

Repiping a house is an expensive endeavor, but it’s absolutely necessary in many cases. With that said, there are a few ways you can decrease the cost of this vital project:

• Choose materials wisely: The pipe materials you choose will have a big impact on your final price, so it’s important to put some thought into your decision. While PEX and CPVC pipes are far more budget-friendly, they don’t offer the long-term durability of a more expensive option, such as copper. Carefully balance upfront material costs with lifespan to determine the right pipes for your needs.

• Do your own prep: One way to save money on repiping is to DIY some of the prep work, such as clearing access areas to your old pipes, doing your own interior painting after the project, or even doing your own pipe insulation if you have the know-how.

• Consider partial repiping: In some cases, you may only have to repipe certain sections of your plumbing system, which will be far less expensive than repiping the entire house.
