Poly B Disclosure Guide: What Sellers Generally Need to Know
If you know your home has Poly B and you're selling, disclosure is a real question — here's the general practice, with the caveat that this isn't legal advice.
Disclosure obligations are a legal matter that varies by province and situation — confirm specifics with your realtor or a real estate lawyer, not this page.

The General Practice
The General Practice Around Disclosing Known Issues
In most Canadian jurisdictions, sellers are generally expected to disclose known material defects or issues that could affect a buyer's decision or a property's value — Poly B, once known, commonly falls into that category given its documented failure history and impact on insurance and financing.
The specific legal disclosure requirements vary by province and by the exact facts of your situation, which is why this page describes general practice rather than telling you definitively what you're required to disclose — that's a question for your realtor or a real estate lawyer.
Why Proactive Disclosure Tends to Help
Why Being Upfront Generally Works in Sellers' Favour
Beyond any legal requirement, proactive disclosure is often viewed favourably by buyers and their agents, since it signals transparency rather than something being uncovered later during an inspection or after possession — which can create bigger problems, including potential disputes.
It also lets you frame the conversation on your own terms, whether that's alongside a firm replacement quote, a price already adjusted to reflect it, or a plan you've already put in motion — rather than reacting to a buyer's inspector flagging it unexpectedly.
The Two Practical Paths
How Disclosure Typically Plays Out in Practice
Some sellers disclose and let it factor into negotiation, referencing a firm quote (see our cost breakdown) so buyers have a real number rather than guessing. Others choose to replace it before disclosure even becomes a live issue, removing it from the conversation entirely — see our selling a house with Poly B page for that fuller decision.
Either path is legitimate; disclosure itself is really about being upfront about what you know, not about which specific business decision you make in response.

We can speak to general practice — not your specific legal obligation.

Getting a Real Number
Get a Firm Quote for Whichever Path You Choose
Whether you're disclosing and negotiating or planning to replace before listing, a referral to a licensed contractor gives you the real, fixed number to work with — talk to your realtor or a real estate lawyer for the legal side of the decision.
Working With Your Realtor
How Your Realtor Fits Into This
Your realtor has likely handled other sales involving Poly B and can advise on standard disclosure language and how it's typically framed in your specific market — that practical, market-specific experience is a valuable complement to the legal guidance a real estate lawyer can provide.
Bringing a firm replacement quote to that conversation, if you have one, tends to make the disclosure discussion more concrete and less speculative for everyone involved.
If you're at all uncertain about what you're required to disclose in your specific situation, err on the side of asking a professional rather than guessing — the cost of a short consultation with a real estate lawyer is small compared to the risk of a dispute after closing.
Common Questions
Frequently Asked Questions
Am I legally required to disclose known Poly B when selling?
This varies by province and situation — general practice leans toward disclosing known material defects, but confirm your specific obligation with a real estate lawyer or your realtor. Because these rules genuinely differ by province and by the specific facts of a sale, treating any general online guide, including this one, as a final answer rather than a starting point is where homeowners sometimes run into avoidable trouble.
Is this page legal advice?
No — it describes general practice only. For your specific legal disclosure obligation, consult a real estate lawyer.
Does disclosing Poly B hurt my sale?
It can affect negotiation, but proactive disclosure is often viewed favourably by buyers compared to it being uncovered unexpectedly during inspection. We can also provide our documentation in whatever format is useful for that broader conversation.
Should I disclose it or just replace it before listing?
Both are legitimate paths — see our selling a house with Poly B page for the fuller decision between disclosing and replacing beforehand. We're glad to support that process however we can.
Can you give me a number to reference if I disclose it?
Yes — a referral to a licensed contractor gives you a firm, fixed replacement quote you can reference in disclosure or negotiation. We're happy to be part of that conversation by providing the firm number — the legal specifics are best confirmed with a professional in that field. We're glad to help however is useful.
Do I have to disclose Poly B when selling?
Do I have to disclose Poly B depends on your province and on what you actually know, and this page is not legal advice. What is consistent is that a Poly B condition of sale - an inspection condition, a holdback, a price adjustment - is a normal way for it to get handled once it is on the table.
In Short
Poly B Disclosure Guide — The Short Version
Disclosing known Poly B when selling is generally viewed favourably and, in most jurisdictions, expected for known material defects — though your specific legal obligation depends on your province and situation, which this page can't confirm for you. Whether you disclose and negotiate or replace before listing, a referral to a licensed contractor gives you a firm number to work with. This guide can tell you what's generally common practice, but only a real estate lawyer familiar with your province and situation can tell you what you're specifically required to do — treat the two as complementary, not interchangeable, sources of guidance. That's the honest answer we can give.
