How Long Does It Take To Repipe A House?

Typically, repiping a whole house can be completed within a timeframe of two days to one week. The process involves several key stages, such as demolishing and preparing the area, installing new pipes, conducting inspections, and adding final touches. 

Day 1-2: Preparation and demolition

The process of repiping a house commences with a thorough inspection by the plumber. This involves examining the water supply lines and shutting them off as necessary. Concurrently, the plumbing agency will initiate the process of securing the requisite permissions for repiping. 

Upon receiving approval, their team will conduct a detailed assessment to pinpoint the location of the current pipes. If access to the pipes proves challenging, they will proceed to demolish sections of drywall to reach the water lines.

Day 1-3: Installing new pipes

Historically, galvanized pipes were commonly used in older American homes. However, modern plumbers now prefer utilizing PEX or copper pipes due to their durability and ease of installation. Consequently, these new PEX or copper pipes will be installed by plumbers throughout the entire home. It includes:

  • Making holes in walls and floors
  • Cleaning the holes for better installation 
  • Installing new pipes and related systems 

Demolition and installation are necessary, making it essential to enlist the expertise of a skilled plumber to reduce the chances of extensive drywall and wall damage, as well as the removal of outdated pipes. 

Day 3-5: Inspections and finishing touches

Once the new pipes are in place, the plumber will notify the municipal inspector. Upon approval of the repiping and plumbing job, the inspector will give the go-ahead. The plumber will then fill any holes and test out the updated plumbing system. 

After a final inspection to ensure everything is in order, the plumber will hand over the newly repiped home to its owner.

What Affects the Repiping Time of a Home?

Several factors influence the repiping of a residence, including the house’s dimensions, the types of old and new piping materials used, their accessibility, and the expertise of the plumbing crew. 

Size of your home:

Homes ranging from 500 to 1200 square feet will typically require two to three days for repiping, while larger homes exceeding 1500 square feet may need three to five days. 

For houses over 2000 square feet, the process of redoing the entire plumbing system can take around one week due to the increased scale of work involved. 

Pipe materials:

In older homes, the prevalent presence of polybutylene or galvanized steel pipes signals that they are nearing the end of their lifespan. As a result, their removal demands careful handling, prolonging the pipe removal process and impacting the overall repiping timeline. 

Conversely, PEX and copper pipes offer ease of removal and installation, thereby streamlining the repiping procedure and requiring less time to complete.

Pipe accessibility:

Not all the pipes in your house are conveniently located for access. Some are hidden within the walls and pass through intricate areas of the house. Additionally, in older homes, the plumbing layout is intricate, making it difficult to reach the pipes. 

Therefore, the duration needed to repipe your home will be influenced by how easily accessible the pipes are, which often involves removing drywall. Moreover, numerous pipes could be situated under concrete, flooring, or on the rooftop, further affecting the time required for pipe removal and reinstallation.

Team size:

The pace of repiping a home is directly influenced by the number of plumbers involved in the project. Having a smaller team of 2 to 3 plumbers will result in a longer duration for the task, whereas a larger team of 5 to 7 plumbers will expedite the process. 

Therefore, it is advisable to communicate your budget and timeline constraints with the plumbing agency. By doing so, their experts can assess your requirements and inspect the property to determine the optimal number of plumbers and estimated duration needed for completing the repiping job efficiently.

When To Repipe A Home?

If you’re ever curious about the right time to replace a home’s piping, keep an eye out for signs indicating that the pipes are in need of immediate replacement due to damage. 

  • If a house was constructed prior to the 1990s, it may be necessary to promptly replace its pipes. Typically, pipes have a lifespan of 20 to 30 years, so evaluating the age of the pipes is essential in determining if repiping is needed. 
  • Occasionally, ongoing leaks indicate water supply line damage, necessitating replacement. Additionally, slab leaks signal pipe damage and the need for reinstallation.
  • Do the pipes often get clogged? This is likely due to the corrosion of the pipe material, causing blockages to occur more quickly. To prevent additional damage, it is recommended to replace the pipes.


Repiping a home typically takes anywhere from two to seven days. If the project involves replacing water heaters, faucets, and other plumbing fixtures, the timeline may be extended. Upon hiring a professional plumber, they will assess the existing water lines and provide you with an estimate for the repiping work, allowing you to plan accordingly based on their recommendations
