Insurance Broker Partner Programme
A Partner Who Protects Your Name
When you send a client to Cornerstone after a loss, your name is on the line. We protect that trust — and keep you updated — on every claim we handle.
Independent Scope Review
We check the full scope of your client's loss to make sure nothing is missed. If there's a gap, we find it and put it in writing before the work starts.
Appraisal-Ready Documentation
Every report we build is ready for a formal claim review. If the file ever goes to dispute, your client already has the paperwork they need — done right the first time.
We Manage the Whole File
One team handles everything — the scope, the estimate, the rebuild, and the updates. You don't chase anyone, and neither does your client.
Your Client Stays Yours
A bad claim can cost you a client. We make sure the experience is smooth and professional, so the trust your client has in you stays right where it belongs.

What This Protects
Every Referral Protects Three Things
When you send a client to Cornerstone, you're not just passing along a name. You're protecting your client, your reputation, and the file.
Your Client Is Cared For
Your client gets a calm, professional team that handles the loss from start to finish. The hardest part of their year is made easier — because you sent them to us.
Your Name Is Protected
A bad claim can cost you a client. We make sure the work is done right, so the trust your client puts in you only grows. You look good because we do good work.
The File Is Documented
We document the full loss clearly and to code. If the claim is ever questioned, your client already has the paperwork they need — and you're never left explaining a gap.
In short —We don't pay you to refer. We protect the client you sent us, so the relationship you built stays yours. That's the whole deal.

Broker Case Study
The Scope Gap a Referred Client Would Have Discovered Too Late
A Durham Region water loss damaged three levels of a home. Before accepting the carrier's rebuild settlement, the homeowner asked Cornerstone for an independent review of the scope.
Rebuild Scope — Side by Side
~$60,000
in code, labour, and line-of-sight rebuild scope the original estimate did not include — every dollar itemized and tied to a code section, an IICRC standard, or the policy's own basis-of-settlement language. Nothing padded.
What the Review Found
- Electrical code deficiencies not in the original scope.
- Documented mould growth that went unaddressed.
- Drywall scoped at roughly half the opened area.
- Line-of-sight finishes omitted in several rooms.
- A wetted wall never opened or moisture-tested.
- Work-at-height labour the original estimate didn't allow for.
And we corrected a charge in the carrier's favour — a double-counted vanity that brought one room's figure below the carrier's number. The goal is an accurate file, not a bigger one.
