How Long Does a Poly-B Repipe Take in a BC Home?

Once you've confirmed your home has Poly-B and decided to move ahead with a repipe, the next question is almost always about disruption. How long will it take, do you need to move out, and what does your daily routine look like during the work. Here's a realistic breakdown of the process and timeline for a typical BC home.

The Short Answer

Most single-family homes in the Lower Mainland and Fraser Valley are fully repiped in one to three days, depending on the size of the home, the number of bathrooms and fixtures, and how accessible the existing pipes are. Larger homes, homes with finished basements, or homes where pipes run through difficult-to-reach spaces can take longer.

There's no single number that applies to every home. The most accurate timeline comes from an in-person assessment, but the ranges below give you a solid idea of what to expect.

What Affects the Timeline

Size of the home. A smaller townhome or one-bathroom home moves faster than a large single-family home with multiple bathrooms, a kitchen, laundry room, and outdoor hose bibs all needing new supply lines.

Number of fixtures. Every sink, toilet, shower, tub, dishwasher, washing machine, and water heater connection is a point that needs new pipe run to it. More fixtures means more connections to complete.

Accessibility. Homes with a crawl space or unfinished basement are generally faster, since plumbers can run new pipe without cutting into as much drywall. Homes where pipes run through finished walls and ceilings on multiple levels take longer because of the drywall cutting and patching involved.

Home layout. Multi-storey homes with plumbing on more than one level typically take longer than single-storey homes, simply because there's more distance for supply lines to travel.

Access points. If your home has good access to the attic, crawl space, or mechanical areas, plumbers can often route new pipe more efficiently than in a home where everything is boxed in behind finished surfaces.

What the Process Actually Looks Like

Day one typically starts with water shutoff and access. The plumbing team turns off the main water supply and begins accessing the existing Poly-B lines, which may involve cutting small access points in drywall near fixtures, in closets, or in the ceiling below bathrooms.

New pipe is run throughout the home. Most BC repipes use PEX pipe, since it's flexible, durable, and well suited to the way homes here are built. The new lines are run from the main shutoff to every fixture in the home, following a route that's often more direct than the original Poly-B installation.

Fixtures are reconnected. Once the new supply lines are in place, each fixture (sinks, toilets, showers, the water heater, washing machine, dishwasher) is reconnected to the new piping.

Water is turned back on and tested. The system is pressure tested to confirm there are no leaks at any of the new connections before the job is considered complete.

Drywall patching. Most reputable plumbing companies handle basic drywall patching as part of the repipe, though paint touch-up is typically the homeowner's responsibility, since matching existing paint colour and texture isn't always something the plumbing crew can do to the standard you'd want.

If a permit is required for the work, which it generally is for a full repipe in BC, an inspection may need to be scheduled as part of the process. Our post on permits for plumbing and gas work in BC covers what that involves.

Do You Need to Move Out During a Repipe?

For most homes, no. You can typically stay in the home during a repipe, though you should expect the water to be shut off for portions of the work, some noise and dust from drywall cutting, and limited access to certain bathrooms or the kitchen at different points during the job.

Larger or more complex repipes sometimes work best in phases, allowing you to keep at least one bathroom functional throughout. If minimizing disruption is a priority for your household, ask your plumber about phasing the work when you're getting your quote.

Comparing Timeline to Cost

The timeline and the cost of a repipe are closely related, since both depend heavily on the size of the home and complexity of access. If you're trying to plan both the schedule and the budget, our post on how much a Poly-B repipe costs in BC breaks down the cost side in more detail.

Getting an Accurate Timeline for Your Home

The ranges above are a starting point, but the only way to get a timeline specific to your home is an in-person assessment. A plumber will look at your home's layout, how many fixtures need to be reconnected, how accessible the existing pipes are, and whether any complicating factors exist, like finished basements or multi-level plumbing runs.

Frequently Asked Questions

Can I use water during a repipe? Water is shut off for portions of the work, particularly while old pipes are being removed and new ones connected. Your plumber will let you know what to expect for water availability each day of the job.

Will I need to repaint after a repipe? Most companies patch the drywall they cut into, but matching paint colour and texture is usually left to the homeowner or a painter, since crews prioritize a clean structural patch over an exact paint match.

Does a repipe include the drain lines too? No. A Poly-B repipe addresses the pressurized water supply lines only. Drain and waste lines are a different system and aren't affected by Poly-B, since Poly-B was only used for supply lines.

Can the whole repipe be done in one day for a smaller home? For a smaller condo or townhome with fewer fixtures, some repipes can be completed in a single day. Your plumber can give you a realistic estimate based on your specific unit.

Do I need a permit for a Poly-B repipe in BC? In most BC municipalities, yes. A licensed plumber will pull the permit and coordinate any required inspection as part of the job.
