Most Victoria homeowners with Poly B pipe know they should deal with it eventually. It sits on the to-do list somewhere between "should handle that" and "maybe next year." But when your insurance broker calls with news about your renewal — a premium spike, a new water damage exclusion, or a flat-out non-renewal notice — the conversation moves from someday to now.
If you own a home in Greater Victoria built between 1978 and 1995, there is a strong chance it has polybutylene plumbing. And across British Columbia, insurers are paying closer attention to that grey pipe than ever before.
This guide breaks down what BC insurers are doing, what questions to ask your broker, and how proactive Poly B replacement can protect both your home and your coverage.
How BC Insurers View Poly B
Insurance companies assess risk — and Poly B pipe is an aging, known-failure-point material. Polybutylene degrades from the inside out as chlorine in municipal water attacks the pipe wall. It can look perfectly fine on the outside and be crumbling on the inside. For an insurer, that is a water damage claim waiting to happen.
The trend across BC is moving in one direction. More insurers are:
- Adding exclusions — removing water damage coverage on policies for homes with Poly B, meaning a burst pipe claim may be denied outright
- Increasing premiums — charging more to reflect the elevated risk of insuring a home with aging polybutylene plumbing
- Declining to renew — some insurers are simply choosing not to offer continued coverage to Poly B homes at renewal time
- Requiring replacement timelines — asking homeowners to commit to a Poly B replacement within a set period as a condition of continued coverage
Not every insurer is handling it the same way, and timelines vary. But the direction is clear — Poly B is becoming a liability that insurers are less and less willing to carry.
What to Ask Your Insurance Broker Right Now
If you know your home has Poly B — or you suspect it does — contact your insurance broker before your next renewal. Do not wait for them to contact you. Here are the specific questions to ask:
- Does my current policy have any exclusions related to polybutylene pipe or water damage from plumbing failures?
- Is my premium being increased because of Poly B, and if so, by how much?
- Is there a risk of non-renewal at my next renewal date because of Poly B?
- If I replace the Poly B, what documentation do you need, and will it restore full coverage or lower my premium?
- Is there a deadline or timeline you need me to meet for pipe replacement?
Having this conversation early gives you time to plan the replacement on your own terms — rather than scrambling after a non-renewal notice lands in your mailbox.
What Insurance Does and Doesn't Cover
This is where many homeowners get confused, so it is worth being clear:
Water damage from a Poly B failure — may be covered
If your Poly B pipe bursts and causes water damage to your floors, walls, or belongings, your policy may cover the restoration and repair of that damage. However, this depends entirely on your specific policy wording and whether any Poly B-related exclusions are in effect. Verify this with your broker.
Poly B pipe replacement — not covered
Insurance does not pay for the cost of replacing your Poly B pipe. It is considered a home maintenance and improvement item, not an insurable loss. The replacement itself is the homeowner's responsibility regardless of whether a failure has occurred.
The takeaway: even if you have coverage for water damage today, that coverage can change at your next renewal. And the pipe replacement itself will always be out of pocket. The question is whether you do it proactively — or after a failure forces the issue.
What Happens at Renewal for Poly B Homes
Renewal is when the reality of Poly B typically hits. Your insurer reviews your file, and if your home still has polybutylene pipe, a few things can happen:
- Your policy renews as-is — increasingly rare for Poly B homes, but it does still happen with some insurers
- Your premium increases to reflect the elevated risk
- A water damage exclusion is added, meaning any Poly B leak claim would be denied
- You receive a non-renewal notice and need to find a new insurer — which is harder and often more expensive when Poly B is disclosed
If you are shopping for new coverage with Poly B still in your home, be prepared for higher premiums, restricted coverage, or outright declines. Fewer insurers are willing to write new policies on Poly B homes, and the ones that do are pricing in the risk.
The strongest position you can be in at renewal is to have the Poly B already replaced, with a plumbing permit and inspection certificate to prove it.
The Mortgage Angle
Insurance is not the only side paying attention. Some mortgage lenders in BC are also beginning to flag Poly B as a concern. Your mortgage requires you to maintain adequate home insurance — so if you lose your policy because of Poly B, you could find yourself offside with your lender as well.
For homeowners buying or refinancing, a property with Poly B can complicate the process. Some lenders are requesting proof of replacement or requiring it as a condition of financing. Buyers are increasingly aware of the issue too, and Poly B is a common negotiating point in real estate transactions across Victoria.
Replacing Poly B before you sell — or before your next mortgage renewal — removes a potential obstacle and protects the value of your home.
Using Insurance Requirements as the Case for Proactive Replacement
The insurance conversation often provides the clarity homeowners need to act. When you weigh the cost of Poly B replacement against the cost of rising premiums, the risk of losing coverage entirely, and the potential for an uninsured water damage event, the math becomes straightforward.
A proactive replacement on your timeline — with a licensed plumber, a proper permit, and a passed inspection — gives you:
- Full documentation to provide to your insurer and broker
- The strongest possible position at your next renewal
- Peace of mind that a hidden pipe failure will not cause thousands in uninsured water damage
- Added resale value and a clean inspection report when you decide to sell

"We had a homeowner in Saanich call us after receiving a non-renewal notice from her insurer. She had been in the same home for over twenty years, never had a claim, and her insurer told her they would not continue coverage because of the Poly B still in the walls. She called us the same week.
We assessed the home, replaced the Poly B with PEX-A, and had the inspection signed off within the week. She sent the documentation to a new broker and had a policy in place before her old one expired. That is the situation we see more and more — and the earlier you get ahead of it, the more options you have."
