Discolored Water

If the water flowing in your plumbing systems has turned brown, red, or just discolored, this could be a sign that your metal pipes have gotten rusty or moldy. Once you notice this, stop using the water immediately since it is most likely contaminated. Ideally, repiping your home to the affected parts could be the best solution.

Weird Tasting Tap Water from Rust and Mold

Rust and mold will change the taste of your water just like the minerals that dissolve in it. Therefore, any sudden change in the taste of your water is a sign it is time to consider repiping your home. Once you realize the taste of your water has suddenly changed, stop drinking or bathing your tap water until you have the pipes inspected by a professional plumber.

Frequent Leaks and Clogs

An occasional leak or clog is normal in any plumbing system, however, if your pipes are leaking quite frequently or getting clogged up, it could be a sign that your PVC pipes are damaged. The surest way to stop these persistent leakages or clogging is to repipe your home.

Low or Inconsistent water pressure from deformed pipes

Broken or deformed corroded pipes is yet another sign that it is time to repipe your house. Broken or twisted pipes can lead to wild swings in water pressure or to a gradual reduction in pressure in your piping system. This is not an inconvenience in the short term, but the water building up in many of your pipes can increase the risk of corrosion or mold.

Mold Growth on Water and Sewer Pipes

If you haven’t noticed any change in water quality or pressure problems with your plumbing system, it is best to keep an eye out for mold that grows near pipes. Pinhole leaks can lead to the growth of mold by spreading moisture in otherwise dry parts of your plumbing system without having any noticeable effect on water pressure.

Even though these small leaks can often be handled by minor plumbing repairs, if they occur in multiple parts of your home, you may require to do a repiping project.

These are some of the problems that are inconvenient and a threat to your health and safety as far as plumbing systems are concerned. Therefore, it is important to respond swiftly by rescheduling an inspection and repiping your house. If you have any severely damaged CPVC pipes, don’t hesitate to replace them.

What Does It Cost to Repipe a House

Repiping a 1,500 square foot home can cost you between $2,280 and $4,000 or between $0.40 to $2.00 per linear foot. However, this will depend on the type of pipe you intend to use. Besides, the accurate plumbing costs of your home will also be determined by the number of bathrooms that are there and how far they are from the kitchen, where the laundry room is and the number of fixtures that are there.

The cost of this plumbing project varies extensively on many factors, the main being the size of the house and the materials used. Homes that are older than 5o years need to be repiped mainly because of the corroded or cracked pipes.

A bigger home will definitely cost more to repipe than a small unit. a home being repiped with copper pipe will equally cost more than one that is being replumbed with PEX pipes.

Cost of Repiping a House with PEX

PEX piping costs range between $0.40 to $0.50 per linear foot. If your home is bigger, then it will cost you more than when small. PEX is a plastic tubing or hose that comes with many advantages when used for repiping a house. However, it has not been around for many years to gauge the health risks of using it in water supply lines for homes.


  • It is easy to install owing to its flexibility
  • It won’t burst if frozen due to its flexibility and will expand to fit
  • It is perfect for both hot-water and cold-water lines repiping
  • It is non-corrosive


  • Cannot be installed outside since UV light will break it down
  • Rodents can chew through it

Estimate Cost to Repipe with Galvanized Pipes

The cost to repipe galvanized pipes is between $2,000 to $15,000 on average depending on whether you want to use copper, PEX pipes, or another material. To replace galvanized pipes in older houses is crucial since galvanized pipes tend to degrade over the years. This is because galvanized pipes are made by coating steel pipes with zinc. As they age, the zinc erodes to expose the steel. The exposed steel will then rust and blockages can occur, pressure drops because of the blockage and your water gets discolored due to the rust. Rusty water is unhealthy to drink and will discolor your clothes if used in the laundry.

Average Cost of Repiping a House with Copper Pipes

The average cost to copper piping a home with copper pipes is roughly $8,000 to $16,000 or between $3 to $8 per linear foot. To replace plumbing systems such as galvanized drain, vent pipe, and sewer lines with copper can cost you between $13 to $15 per linear foot. This is because the copper pipe is quite expensive than PEX pipes, but comes with exceptional benefits.

  • It is naturally resistant to bacteria
  • It is recyclable and easy to install, though not as easy as PEX, but still convenient.
  • Copper is resilient to breakages thus good for areas prone to earthquakes.

Average Cost of Removing Existing Plumbing Pipes

Removing hazardous piping materials before repiping can cost you between $1,000 to $5,000 in an older house. This estimate is often included in the price of repiping a house rather than being treated as a standalone cost. Besides, it involves a “remove as you go” type of repair to repiping in an entire house, therefore, it is not a task you can do yourself to save some money.

However, this re-plumbing cost is dependent on the size of the house, the number of bathrooms, and plumbing fixtures such as laundry room, wet bar, mudroom among others. Also, the cost to repair the drywall that was cut into to access the plumbing fixture will add about $500 or more to your overall costs.

Average Cost to Repipe an Old House

A home that is over 50 years is due for repiping at a minimum cost of $2,000 and a maximum of $15,000. Note that the wide disparity of the price is because of the size of the home, the type of pipe you are using to repipe, and the extra repairs you may need to do any time you cut into the drywall.

So how long do plumbing pipes last before replacement is due?

  • Brass pipes are said to last between 40 to 70 years
  • Galvanized steel pipes can last from 20 to 50 years
  • Copper pipes can last up to 50 years

Factors that will Impact the Average Cost to Repipe a House

As we already mentioned above, the overall cost your will pay for repiping your home will depend on some essential factors. Let’s explore these crucial factors in detail.

Number of Plumbing Fixtures in your Home

Plumbing fixtures such as the bathroom, kitchen sink, shower, bathtub, toilets, washing machine, water heater, dishwasher among others will substantially impact your overall cost. The more of these fixtures you have the more expensive the repiping project will be. This is because you will be replacing more pipes and require more workers to get the work done thus increasing the cost to repipe.

Type of Repiping Material

Piping Material Cost per Linear Foot Features
Copper Pipes $2 to $8 Environmentally friendly

Resistant to corrosion and cracking

Most expensive pipe

May develop pinhole leaks if used with hard water

CPVC Pipes $0.50 to $1 Made of chlorinated polyvinyl chloride

Can withstand high water temperatures

Rigid plastic thus may be brittle over time

Best for hot water lines

PEX Pipes $0.50 to $1 Made of cross-linked polyethylene


Easy to install

Flexible plastic

Size of Your Home

Obviously, the bigger your home is, the more expensive the repiping project will be. This is because such plumbing jobs will need more piping material, more installation time as well as extensive labor. Moreover, repiping a multi-story home will even be costlier as the repiping plumbers will have to navigate through the walls and ceilings to install the pipes. Besides, they will have to demolish some walls to replace the vertical pipes.

Access to Each Fixture

Repiping fixtures especially in hard-to-reach areas of your house can cost more just because it takes longer to work therefore substantially increasing the cost of labor. For example, if you require repiping in your crawlspace, slab foundation, or closet, you can be sure to pay more.

Plumbing Contractor’s Cost

A plumbing contractor will first inspect your home before providing you a cost estimate of repiping. So, once you settle down to the right one, make sure the contract includes all the required details regarding the project planning, equipment, and material acquisition, area preparation, and protection, set up as well as final cleanup.

Also, ensure that the contractor is insured and has no customer complaints with the Better Business Bureau. Most importantly, check their online reviews regarding the quality of work and customer service. Note: Avoid a plumbing company that demands full payment upfront or declines to pull the essential permits and obedience to the local building code.

Local Permit Fees

Without a doubt, a major repiping project requires permits and inspections. Even though the permit fees might vary from one state to another, the common cost runs between $70 to $400. However, if the inspection reveals that your plumbing system needs some upgrades to get it to code, then the permit fees are bound to increase your repiping cost even further. Often, plumbing companies include the permit fees in the overall bid on your home repipe project.


If your home plumbing system is older or has been damaged beyond repair, shows signs of corrosion, rusting, or decay, it is high time to get them replaced. The earlier you repipe the better. Besides, you don’t want the leaks from these pipes to cause water damage in your home thereby costing you an arm and a leg in repairs and major plumbing renovation!
