We get a lot of calls from Kelowna homeowners who've just opened a renewal letter from their insurer. It usually says some version of the same thing: replace your poly-B within 60 to 90 days, or we won't renew your coverage.
It's a stressful letter to get. But here's the thing most homeowners don't realize: the smarter move — and the cheaper one — is to act before that letter shows up. Here's why.
What's changed with insurance and poly-B
For years, poly-B was barely a footnote in home insurance — maybe it bumped your premium up a bit. That's changed. Insurers are now sending non-renewal notices, and sometimes mid-term cancellations, to homes with confirmed poly-B. This isn't just a couple of smaller providers doing it either — it's becoming standard across the major Canadian carriers.
The reason is simple: water damage is the most expensive kind of claim in Canadian home insurance, and a poly-B failure typically runs $15,000 to $40,000 in remediation, depending on how long the leak goes undetected. Once that risk is tied to one specific, identifiable pipe with a known failure pattern, insurers stop treating it as bad luck.
Heads up: These deadlines are usually 60 to 90 days from the notice date. Miss that window and your coverage lapses, and finding a new insurer willing to cover a home with known poly-B on short notice gets difficult and expensive. If you've got a mortgage, your lender may step in and force-place insurance for you — often at two to four times the normal cost.
Why proactive replacement beats waiting for the letter
Here's what we see happen when homeowners wait for their insurer to force the issue:
Reactive replacement
Forced by insurer
60 to 90 day deadline. You're booking in a rush, competing with other homeowners in the same boat, and there's less room to compare quotes or work around your schedule.
Proactive replacement
On your terms
You book when it suits you, get a few quotes to compare, work around holidays or family schedules, and have time to get the house ready. No deadline breathing down your neck.
There's a money angle too. A lot of homeowners recoup some of the cost through better home value and lower premiums after replacement. Doing the work on your own timeline — and handing your insurer the permit and completion certificate — also puts you in a stronger spot when it's time to negotiate renewal, rather than scrambling under a deadline.
The real risk: poly-B fails without warning
Poly-B breaks down from the inside, and there's no way to tell from the outside how far along that is. A pipe that looks fine can rupture without any warning. If that happens behind a wall or under flooring, you're looking at serious water damage, mould, and structural issues — often before anyone even notices.
This matters even more here in the Okanagan. Our municipal water treatment, plus the pressure swings between hot summers and cold winters, speeds up the breakdown. Most poly-B in Kelowna homes went in between 1985 and 1998, so it's now pushing 30 years old — well past what it was ever built to handle.
A note on water damage claims: A lot of insurers cover sudden pipe failures but exclude gradual deterioration. Some will deny a claim outright for known poly-B — meaning if your insurer already knows you have it and a leak happens, you might not be fully covered. Worth checking your policy's exclusions closely.
What happens if I only replace part of it?
We don't recommend partial replacements. Mixing poly-B with newer pipe raises the risk of connection failure, and it may not meet building code or your insurer's requirements either. A full replacement is really the only way to get rid of the risk for good.
We see this sometimes — a past owner swapped out the poly-B under the sinks but left the rest in the walls. Insurers and home inspectors will still catch it, and you'll end up finishing the job eventually anyway. Doing it all at once is cheaper than doing it in stages.
What the replacement process actually looks like
A lot of homeowners put this off because they imagine it's a huge disruption. It's less disruptive than you'd think:
We walk the home, confirm the scope, and give you a fixed quote within 24 to 48 hours. No pressure, no commitment.
We keep at least one bathroom running throughout the job, so your day-to-day isn't completely thrown off.
Old poly-B comes out, new PEX goes in. We patch, texture, and paint the drywall. Most Kelowna homes are done in 2 to 5 days.
You get a Certificate of Completion and a copy of the closed permit — exactly what your insurer needs to update your policy.
What about selling the home?
If you sell, home inspectors almost always flag poly-B as a defect. Buyers use it to negotiate the price down, or ask for full replacement as a condition of sale. If you're planning to sell in the next few years, getting it replaced now takes that off the table and protects your asking price.
It also gives you time to get a few quotes and plan things properly, instead of rushing a replacement with a closing date bearing down on you.
The bottom line
Poly-B replacement isn't cheap. But doing it on your terms — planned, fixed price, no deadline breathing down your neck — almost always costs less than an emergency repair, water damage cleanup, temporary coverage, and a rushed job booked under your insurer's ultimatum, all added up.
