What is Involved with Repiping a House?

Your home’s plumbing requires regular maintenance, just like any other aspect of your house. Over time, pipes can corrode, leading to leaks and other issues that can result in low water pressure, discolored water, or strange noises. If you find yourself spending a significant amount on repairs, living in an older home, or planning a remodel, it may be time to consider repiping your house. In this article, we will explore the essential steps involved in repiping a house, including what to expect from the renovation and how to determine if it’s the right time for a repiping project.

What Does Repiping a Home Mean?

Repiping involves replacing the old plumbing system in your home with a newer, updated one. This is typically done in older homes with deteriorating pipes or significant problems, as well as during major home renovations.

When Should a Homeowner Consider Repiping?

Deciding to repipe your home is a significant undertaking. Here are some signs that indicate it’s time to consider repiping:

1. Your Home Has Lead Pipes or Galvanized Steel Pipes

Many homes built over a century ago were fitted with lead pipes, which pose a health hazard when lead leaks into the water supply. Even though many older homes have had updates, it’s crucial to check if your home still has lead pipes. Another common material used in older homes is galvanized steel, which is prone to corrosion that can cause leaks or lead to sediment in the drinking water.

2. Repairs Are Becoming Frequent and Costly

If your pipes constantly experience leaks or other problems, the cost of plumbing repairs can quickly add up. In such cases, it’s more cost-effective to repipe your home and address the recurring plumbing issues. Repiping will also provide you with a brand-new system designed to last for decades.

3. You’re Planning a Home Remodel

If you’re remodeling your kitchen, bathroom, or adding new rooms, it’s an opportune time to consider repiping your home and updating your plumbing system. By doing so, you can avoid potential issues that may arise when connecting the new and old systems during the remodel.

Before You Begin: Inspection and Estimate

Embarking on a full repiping project for your home is a substantial investment and renovation. It’s important to bring in a professional plumber to inspect your old plumbing system and provide an estimate for the work. It’s advisable to seek multiple estimates from local plumbers to determine the best offer. Based on your budget and preferences, you can then decide whether to fully repipe your home or tackle the project in stages.

The Repiping Process: What to Expect

During the repiping process, your home will undergo construction in most rooms. Here’s an overview of what you can anticipate:


Plumbers will need to cut holes in the drywall to access the old pipes and install the new ones. It’s essential to move all furniture away from the work area and cover it to protect against dirt and potential damage. Valuables such as flat-screen televisions, art, or other decor should also be taken into consideration.

During the renovation, your water supply will need to be shut off temporarily. Although you will have access to water from the old pipes for some time, as the plumber constructs the new system alongside the old one, there will be periods when the water will be completely off while the plumber connects the new system.

Plumbers Need Access

To install the new pipe system, plumbers will need access to the drywall in multiple rooms. Before the project begins, make sure to clear the way by moving furniture, artwork, or wall hangings that may obstruct the plumber’s work.

Duration of the Process

The duration of a repiping project can vary depending on the size of your home and the number of bathrooms. Typically, repiping can take anywhere from two to three days to a week. During this time, there will be temporary water disruptions. It is advisable to discuss with your plumber strategies to minimize the impact on water usage.

Similar to other renovations, obtaining a work permit for repiping is necessary. This should be done after the initial inspection and estimate, ensuring compliance with local regulations.

Inspection and Finishing

Once the new pipes are installed, it is crucial to have a professional inspection to ensure the quality of the work. After receiving approval from the inspector, your plumber can proceed with patching the drywall and repainting your walls, leaving them looking brand new.
