What Does Repiping a House Mean?

Repiping a home is a process in which a plumber replaces old pipes with new pipes in your entire plumbing system. This is typically done when homes are older and the pipes are corroded or damaged, but some homeowners elect to repipe their homes when they remodel or renovate other rooms.

When Would a Homeowner Need to Repipe a House?

How can you tell when it’s time to repipe your home? Here are some signs to look out for:

Your Home Has Lead Pipes or Galvanized Steel Pipes

Homes that are a century old (or older) may have lead pipes. This common material was used in many homes from this period, but it was found to cause health problems when lead leaks into the water source. Though many of these homes have had repiping, it’s crucial that you check your home for lead pipes and update them.

Galvanized steel was also used in many older homes, typically from the 1940s to 1960s. These pipes are durable and were commonly used at the time. However, they corrode easily and can restrict the flow of water. They’re also prone to leaks and may cause sediment to contaminate the water supply.

No Matter How Many Times You Fix Your Pipes, They’re Still Broken

If you’re dealing with constant plumbing repairs and expensive bills, it may be time to just repipe your home. These small repairs add up, and it may be a more practical and cost-effective decision to simply upgrade your old plumbing system to a new one.

You’re Remodeling Your Home

If you’re adding a kitchen, bathroom, or new plumbing fixtures, this is a good time to evaluate your old system and whether it’s time to repipe. It’s a big undertaking but pairing new systems with old ones can create more problems. It may be best to bite the bullet and repipe your entire home.

Before You Start – Get an Inspection and Estimate

Repiping is an overhaul of your home’s plumbing and a big investment. Before you take on this renovation, contact several plumbers to get estimates and inspections. You can then see which company is the best fit for your needs.

What is Truly Involved in Repiping a House

A full repiping of your home will involve many rooms in your house. Here’s how you can prepare for the process:


Installing new pipes will mean renovations in most rooms in your home. It’s important to do your part and cover your furniture and décor to protect it from damage or dirt during the process. You may want to pack up fragile décor and move it to a safe place.

You should also remember that your water service will be cut off during some parts of the process, so speak to your plumber about minimizing the time you’ll be without running water.

Plumbers Need Access

Plumbers install new pipes by cutting holes in your drywall and constructing the new pipes next to the old ones. You should move furniture or wall hangings out of the way to provide access to your drywall and give the plumber room to work.

How Long Does the Process Take?

Repiping can take anywhere from a few days to a week, depending on the size of your home and the number of rooms with plumbing. Remember that you’ll have open drywall and some water shut off during that time, so plan your day accordingly.

A full repiping of your home is a major renovation that requires a permit from your municipality. This should be done after the initial work is complete.

Inspection and Finishing

After the plumber is done working, you will need to bring in an inspector to check the work and approve it. Once the inspection is done, your plumber will be free to repair and repaint the drywall and get your home looking like new.
