Home Insurance and Poly B: What Your Insurer Actually Wants
If you've been told your home insurance is at risk because of Poly B pipe, you're not imagining it. Here's what's really going on with insurers and polybutylene, and what actually gets your coverage back to normal.
Canadian insurers increasingly decline, non-renew or surcharge homes with Poly B — some require full replacement to bind or renew a policy at all.

What's Changed
Why Insurers Care About Poly B
Poly B has a documented history of failing unpredictably, often at fittings and joints, sometimes years after a home was built with no visible warning sign. Insurers price risk, and a plumbing system with a known pattern of surprise leaks is exactly the kind of risk they've been tightening up on across Canada.
That's why home insurance and Poly B have become linked in a way they weren't a decade ago — it's no longer just a plumbing question, it's underwriting.
It also isn't unique to any one insurer. The shift has been broad enough across the Canadian home insurance market that Poly B now regularly comes up in renewal conversations and new-policy applications alike, not just after a claim.
What Insurers Actually Do
Decline, Non-Renew, or Surcharge
The real pattern is one of three outcomes: an insurer declines to write a new policy on a home with known Poly B, an existing policy isn't renewed at term, or the homeowner is offered continued coverage at a higher premium (a surcharge) to reflect the added risk. Some insurers go further and make full replacement a condition of binding or keeping the policy at all.
Mortgage and closing conditions can compound this — a lender or a buyer's insurer may flag Poly B during a purchase, which is a separate but related pressure point covered on our buying a house with Poly B page.
Getting Coverage Back
What Actually Restores Your Coverage
The path back to standard coverage is consistent across most insurers: replace the Poly B, not patch it. Because the whole system ages and degrades together, insurers generally treat a full replacement — not a spot repair — as the thing that resolves the underlying risk.
We can't promise what any individual insurer will decide, and we never guarantee an outcome — that call is always your insurer's. What we can do is give you the documentation they'll typically ask for.
Timing matters too — starting the replacement conversation before a renewal deadline or before a new-policy application, rather than after a decline letter arrives, generally gives you more room to work with your insurer or broker on next steps.

The Bigger Picture
Insurance Is Often the Real Trigger
For a lot of homeowners, the insurance letter is what actually starts the clock on replacing Poly B — not a leak, not an inspection, but a renewal notice or a new-policy application that comes back declined or surcharged. If that's where you're at, you're not alone, and it's one of the most common reasons we hear from homeowners booking an assessment.
Once you know that's the trigger, the next practical step is usually the same regardless of which insurer you're dealing with: get a firm quote and a realistic timeline, then take that information back to your broker so they know a plan is already in motion.

Common Questions
Frequently Asked Questions
Will my home insurance really be affected by Poly B?
It can be — many Canadian insurers now decline, non-renew or surcharge homes with Poly B. Policies and practices vary by insurer, so it's worth checking directly with yours.
Does insurance cover the cost of replacing Poly B?
Generally no — replacement is typically treated as proactive maintenance, not a covered claim, unless there's already been a loss. Your insurer's policy wording governs this, not us.
What actually restores my coverage after replacing Poly B?
Most insurers look for full replacement rather than a spot repair, plus documentation showing the work was completed. We provide that documentation as part of every job.
Can you guarantee my insurer will restore my policy?
No — that decision is always your insurer's. We give you a completed, documented replacement and the paperwork; the underwriting call belongs to them.
Is Poly B also an issue when buying or selling a home?
Yes — it's a common inspection and financing flag on both sides of a sale. See our buying a house with Poly B page for more on how that plays out for purchasers specifically.
