How Insurers Approach It
Poly B Insurance Companies: How Insurers Generally Approach It
We won't name specific insurers or claim to know any single company's policy — but here's the general pattern across the Canadian home insurance market, and why it exists.
This is a market-wide underwriting shift, not one insurer being unusually strict — most of the Canadian market has moved the same direction.

A Note Before We Start
Why We're Not Naming Specific Insurers
Individual insurer policies change, vary by province, and aren't something a plumbing company can responsibly claim to know with certainty. Naming specific companies and their supposed Poly B stance risks being wrong, or out of date, the moment it's published — so we won't do it.
What we can speak to honestly is the general pattern across the industry, which is well enough established to describe without needing to point at any one company.
The General Pattern
How Insurers as a Category Tend to Respond
Broadly, Canadian home insurers have moved toward treating Poly B as an underwriting factor — some decline to write new policies on homes with known Poly B, some choose not to renew existing policies at term, and others offer continued coverage at a higher premium to reflect the added risk.
A number of insurers go further and make full replacement a stated condition of binding or maintaining a policy. Which of these applies to you depends entirely on your specific insurer and policy — this is a pattern, not a guarantee of any one outcome.
Why the Pattern Exists
Why Insurers Moved This Direction as an Industry
Insurance pricing is built on risk data, and Poly B's documented history of unpredictable failures — leaks and bursts that happen without warning, often years after installation — is exactly the kind of pattern that shows up in claims data across an industry, not just at one company.
That's why the shift has been broad rather than isolated to a single insurer being unusually cautious — the underlying risk data is shared knowledge across the market.

How to Find Out Where You Actually Stand
General patterns are useful context, not a substitute for your own policy.
The only reliable source for your specific policy's stance on Poly B.
Useful whether your insurer requires it now or you're getting ahead of a future renewal.

Getting Started
Get Ready for the Conversation With Your Insurer
A referral to a licensed contractor gives you a firm quote and, once the work is done, documentation your insurer or broker can review — useful groundwork no matter which way your specific insurer leans.
How to Verify Your Own Policy
How to Find Out Your Specific Insurer's Stance
The most direct way to know where your own insurer stands is to ask them or your broker plainly: does my policy currently reflect known Poly B, and what would restore standard terms if it does. Insurers generally have a clear internal answer to this even if it isn't published broadly.
Bring a firm replacement quote to that conversation if you have one — it tends to make the discussion more concrete and can speed up next steps on either side.
It's also fair to ask your broker whether they've seen this pattern with other clients recently — brokers who work with many homeowners often have a practical, current sense of how insurers in your specific market are actually behaving, even without official published policy statements.
Common Questions
Frequently Asked Questions
Which insurance companies cover Poly B homes?
We don't name or claim to track individual insurers' policies — they vary and change. Ask your own broker or insurer directly for your specific situation. We think that's the more honest answer than pretending to have current, verified knowledge of every insurer's internal policy, which changes over time and isn't something a plumbing company is positioned to track accurately.
Do all insurers treat Poly B the same way?
No — the general pattern (decline, non-renew, or surcharge) is common across much of the market, but individual policies and practices differ.
Why have insurers moved this direction as an industry?
Poly B has a well-documented history of unpredictable failures, which shows up broadly in claims data — not just at one company. That's a genuinely useful data point worth asking for directly, even though it's informal rather than official policy.
Is there a list of insurers that won't cover Poly B?
We don't maintain or publish one — insurer policies change and vary, and we'd rather send you to your own broker than guess. We'd rather be useful within our actual expertise.
What should I do regardless of which insurer I have?
Get a firm replacement quote and, once completed, insurer-ready documentation — useful groundwork no matter your specific insurer's stance. We'd rather send you to the right resource than pretend to have insider knowledge of policies we can't actually verify. We'd rather point you to the right source.
What if my insurance won't cover Poly B?
Where insurance won't cover Poly B, the obstacle is usually the market segment you are shopping in rather than one carrier's opinion. A broker who writes across several carriers can find who is still comfortable, and a completed replacement changes the conversation entirely.
In Short
Poly B Insurance Companies — The Short Version
Poly b insurance companies, as an industry, have broadly moved toward treating polybutylene as an underwriting risk — declining, non-renewing or surcharging affected homes in many cases — but we won't name specific insurers or claim to know any single policy. Confirm your own situation with your broker, and get a firm replacement quote and documentation either way. The takeaway isn't which company to avoid or seek out — we won't speculate on that — it's that the underlying risk pattern is real and broadly shared across the industry, which is exactly why proactive replacement tends to put homeowners in a stronger position regardless of which insurer they end up with. That's the fairest answer we can give.
