How Long Does a PEX B Repiping Project Typically Take?

How long does it take to repipe a house? For most single-family homes, the plumbing work takes one day with PEX. Add the city inspection and drywall patching, and the whole project usually wraps up in about three days. Larger, two-story, or harder-to-access homes take longer. This guide walks through what happens each day, what can stretch the schedule, and how to get your home ready.

Here’s the quick version:

• A typical PEX repipe takes one day of plumbing work, then a city inspection, then a day of drywall patching, often about three days in all.
• Home size, number of bathrooms, two-story layouts, access, and inspection scheduling are what change the timeline most.
• PEX installs faster than copper because it bends around corners, needs far fewer fittings, and requires no soldering.
• Most families stay home during a repipe. Plan for the water to be off while the new lines are connected.
• A free on-site inspection is the only way to get a real schedule for your home.

How Long Does It Take To Repipe A House?

For most single-story homes with two or three bathrooms, the plumbing work itself takes one day. The full project, including the city inspection and drywall repair, usually takes about three days. That is the common schedule for the Southern California homes our crews repipe with Zurn PEX.

Bigger projects take longer. For national context, Angi’s repiping guide puts small homes at a few days and big multistory homes with lots of fixtures at up to several weeks. A one-bathroom condo sits at the short end of that range, and a large custom home with long runs and finished ceilings sits at the long end.

A Typical PEX Repipe Timeline, Day By Day

Here is what a standard three-day repipe looks like from the first visit to the last drywall patch.

Before Day One: Inspection, Estimate, And Permit

Every repipe starts with an on-site inspection. We check the existing pipe material and condition, count the fixtures, and plan the routes the new lines will take through the walls, attic, or crawlspace. You get a written estimate, and once you approve it, we pull the plumbing permit with your city. Many homeowners get a quote the same day they call.

Day One: The Repipe

The crew protects floors and furniture in the work areas, then opens small sections of drywall at each fixture and along the planned routes. New PEX lines are run to every sink, tub, shower, toilet, and appliance hookup, plus the water heater and the point where water enters the house. The old supply lines are taken out of service. Because PEX is flexible, most runs go through a handful of small openings instead of long cuts in the wall.

Day Two: City Inspection

The city inspector checks the new lines while the walls are still open. California’s plumbing code requires a new water supply system to hold its test pressure for at least 15 minutes without any sign of leaking. Inspection timing depends on the city’s schedule, which is why this step is often the one that moves.

Day Three: Drywall Patching

Once the inspection passes, our drywall crew closes every opening, patches, and textures the repairs to blend with the surrounding wall. We do our own drywall work instead of leaving holes behind for you to hire out. The patches are left ready for your paint.

After The Crew Leaves: Paint And Final Clean

The crews prep and clean as they go, but plan on a final wipe-down and on painting the patched areas, either yourself or with your painter.

Here is how one recent customer described the repipe and patch days:

Repipe Timeline At A Glance

What Can Make A Repipe Take Longer?

The three-day schedule covers most homes, but these factors can add time. Your estimator will flag them during the inspection so the schedule you get is realistic.

Home Size And Number Of Bathrooms

More fixtures mean more lines to run and more openings to patch. A four-bathroom home with a wet bar and an outdoor kitchen takes longer than a two-bathroom ranch house.

Two-Story Homes And Condos

Lines that run between floors take more planning and more openings. In condos and townhomes, shared walls and building rules can also affect when crews can work and when the water can be shut off.

Slab Foundations And Access

Many Southern California homes sit on a concrete slab, with the original water lines buried underneath. A repipe usually reroutes the new lines overhead through the attic and walls instead of breaking into the slab. That approach is often how homeowners end a run of slab leaks for good. Tight attics, low crawlspaces, and finished ceilings take more time to work through.

Tile, Cabinets, And Finished Surfaces

Pipes behind tile showers, built-in cabinets, or decorative finishes take more care to reach. Good planning routes around them whenever possible.

Older Wall And Ceiling Texture

Some older homes have textured paint or patching compound on walls and ceilings that contains asbestos, which the EPA lists among the places asbestos may be found. You cannot tell by looking, so before a project that opens walls, the EPA suggests having the home inspected by a trained and accredited asbestos professional, who should be the one to take any samples. In an older home, testing ahead of repipe day can add a few days to the start date.

Inspection Scheduling And HOA Approval

Each city runs its own inspection calendar, and some are busier than others. If you live in an HOA, you may also need its approval before the permit is pulled. Neither changes the work itself, but both can move the calendar.

Hidden Damage

Opening walls sometimes reveals old leak damage, rot, or mold that needs to be dealt with before the walls are closed, which can add time.

Is A PEX Repipe Faster Than Copper?

Yes. PEX is flexible, so it bends around corners and runs in long continuous lengths instead of needing a fitting at every turn. There is no soldering, and the expansion fittings we use form a full-strength seal as soon as the connection is made. Fewer joints and no torch work add up to a shorter day on site and fewer, smaller wall openings. Our guide to the benefits of PEX pipe covers the other reasons we recommend it, and our copper vs. PEX B comparison lays out the two materials side by side.

Will I Have Water During A Repipe?

Plan for the water to be off while the new lines are tied in on repipe day. On a typical one-day repipe, service is restored once the new system is connected and tested. Your estimator will tell you what to expect for your home. To make the day easier:

• Fill a few pitchers or jugs for drinking and cooking.
• Run the dishwasher and laundry the day before.
• Plan showers for the night before or after the crew finishes.

A homeowner with a large family shared how the schedule and the water shutoff worked out:

Can You Stay Home During A Repipe?

Yes, most families stay home. Expect noise from cutting and drilling in the work areas and some dust, which the crew contains with plastic sheeting and floor protection. If you work from home, a room away from the bathrooms and kitchen is the quietest spot. Keep pets in a closed room or out of the house for the day so doors can stay open for the crew.

How To Prepare Your Home For Repipe Day

• Clear the area under sinks and around the water heater, washer, and toilets.
• Move furniture and fragile items a few feet away from walls in bathrooms, the kitchen, the laundry room, and hallways where lines will run.
• Clear a path to the attic access and the garage.
• Take down wall art and mirrors in the work areas.
• Arrange parking near the house for the crew’s trucks.
• Let everyone in the household know the schedule and the water shutoff.

Frequently Asked Questions About Repipe Timelines

How Long Does It Take To Repipe A House With PEX?

Most single-family homes take one day of plumbing work. With the city inspection and drywall patching, the project usually takes about three days. Larger and two-story homes can take longer.

How Long Is The Water Off During A Repipe?

The water is off while the new lines are connected on repipe day. On a typical one-day repipe, service is back once the new system is tied in and tested. Your estimator will give you the plan for your home.

Can I Live In My House While It Is Being Repiped?

Yes. Most homeowners stay home during a repipe. Expect noise and some dust in the work areas, and plan around the water shutoff on repipe day.

Does A Repipe Need A Permit In California?

Yes, a whole-house repipe is permitted work in most California cities, and the new lines must pass a city inspection before the walls are closed. Angi puts typical permit fees between $50 and $500, depending on the city. Our repipes include the permit and the inspection.

How Long Does Drywall Repair Take After A Repipe?

On most homes, drywall patching takes about one day and happens right after the inspection passes. The patches are textured to blend in and left ready for paint.

Does A Two-Story House Take Longer To Repipe?

Usually, yes. Lines that run between floors need more planning and more openings. Your estimator will build the extra time into your schedule after seeing the home.

Is A Partial Repipe Faster Than A Full Repipe?

A partial repipe takes less time, but it leaves the rest of the old pipe in service, and the next failure is often close behind. See how to decide between a partial and a full repipe.

What Is The Best Time Of Year To Repipe?

Any time of year works in Southern California. The best time is before the next leak. If you are already planning a remodel or new flooring, repiping first lets you open walls once.
