How Long Does Poly B Replacement Take in Victoria BC?

When homeowners in Victoria find out their Poly B pipe needs replacing, the first question is usually about cost. But the second question — and often the bigger worry — is about disruption. How long will this take? Will we have water? Do we need to move out?

Those are fair concerns. A full Poly B replacement touches every water line in your home, which means plumbers working in multiple rooms over the course of one or more days. But the reality is far less dramatic than most people expect.

In this guide we'll walk through realistic timelines by home type, what affects how long the job takes, and exactly what the process looks like day by day — so you can plan around the work with confidence.

Typical Timelines by Home Type

Every home is different, but after replacing Poly B in hundreds of Victoria homes, here are the general timelines we see:

These timelines cover the active plumbing work only — they don't include the initial assessment visit, permit processing, or final inspection, which happen on separate days.

Factors That Affect Duration

The difference between a one-day job and a three-day job comes down to a handful of factors:

• Home size — more square footage means more linear feet of pipe. A 900-square-foot condo has far less pipe than a 2,400-square-foot split-level.
• Number of bathrooms and fixtures — each bathroom adds hot and cold supply lines, shut-off valves, and fixture connections that need to be replaced individually.
• Wall accessibility — this is the single biggest variable. If your main runs are accessible through a crawlspace, unfinished basement, or mechanical room, the work goes significantly faster. Pipe buried behind finished drywall on every level takes longer to reach.
• Routing options — a skilled plumber will look for ways to route new PEX through existing pathways, chases, and accessible cavities rather than cutting through every wall. Homes with good routing options require less drywall work and finish faster.
• Strata coordination — if you're in a strata complex, there may be restrictions on work hours, noise, or common-area access that affect scheduling. The actual pipe replacement time is similar, but the logistics can stretch the calendar.

During your on-site assessment, your plumber will evaluate all of these factors and give you a clear estimate of how many days the work will take before you commit to anything.

Day by Day — What the Process Looks Like

Here is a typical sequence from first contact through to completion:

How Long Will You Be Without Water?

This is the concern we hear the most — and the answer is usually reassuring. Water is shut off during active work hours while the crew is cutting, connecting, and pressure-testing the new pipe. That's typically during the daytime, roughly 8 a.m. to 4 p.m.

At the end of each working day, your plumber will restore water to as much of the home as possible. In most cases, you'll have functioning toilets, sinks, and showers by the evening — even if the job isn't fully complete yet.

On a single-day job, water may be off for 6 to 8 hours. On multi-day jobs, you lose water during work hours each day but have it back each evening. It's manageable — nothing like the week-long outages some homeowners imagine.

Do You Need to Leave Your Home?

Generally, no. Most homeowners stay in their home throughout the entire replacement. The work is contained to specific areas at any given time, and the crew will communicate clearly about which rooms they need access to and when.

That said, it is an active construction environment during work hours — there will be noise, foot traffic, and temporary dust in areas where drywall is being cut. If you work from home and need quiet, it may be worth planning to work elsewhere for the day. Families with young children sometimes prefer to be out of the house during work hours simply for convenience.

You absolutely do not need to arrange alternative accommodation. By the time the crew leaves each day, your home is livable with water restored.

What About Patching and Painting After?

Any drywall that needs to be cut to access pipe runs will be patched as part of the job. Your plumber will cut small, strategic access holes rather than removing large sections of wall — the goal is always to minimize the impact on your home.

Painting over the patched areas is typically the homeowner's responsibility, and most people find it straightforward. A quick coat of matching paint and the patches blend right in. If you prefer, a handyman or painter can handle it for a modest cost.
