Why your insurance claim was underpaid — and what to do about it
Most underpaid claims are not a conspiracy. They are an arithmetic gap between the carrier's scope of loss and what the work actually costs. Here is how to find the gap and prove it.
A cheque arrives, you look at the number, and it is nowhere near what the builder quoted. This is the most common moment in a property claim, and it almost never means somebody is cheating you. It usually means the scope of loss — the carrier's itemised list of what they think the repair involves — is missing lines that the actual repair needs.
The gap is arithmetic. Which means it can be closed with arithmetic, if you can show your work.
Start by separating three different numbers
People argue about "the claim" as though it is one figure. It is at least three, and confusing them is what makes the conversation go in circles.
| The number | What it means | Where it comes from |
|---|---|---|
| Scope of loss | What the carrier agreed the repair involves | Their adjuster or estimating software |
| Paid to date | What has actually landed in your account | Cheques and drafts, minus deductible and depreciation |
| Cost incurred | What you have actually spent or been invoiced | Your receipts and your builder's invoices |
The shortfall is cost incurred on covered work, minus what the carrier has paid. That last qualifier does most of the work, and it is where most homeowners accidentally weaken their own case.
The mistake that costs people the most
If you total every dollar you have spent on the house and compare it to the insurance payments, you will produce a very large, very wrong number — and the first person to notice will be the adjuster.
On one job we reconciled, the total-out-minus-total-in method produced a shortfall of about $162,000. The defensible figure was $47,496.21. The difference was not fraud on anyone's part. It was upgrades, an added room, a new roof paid for by a family trust, and carrying costs like the mortgage — none of which the carrier ever agreed to cover, and none of which belong in a claim.
An adjuster who finds a mortgage payment inside your claimed repair costs now has a reason to doubt every other line. Overstating a claim is worse than understating it. Put the owner-funded work in a separate column and let the covered work stand on its own.
How to actually find your gap
- Get the scope of loss as a line-item document, not a summary. Ask for the estimate export if they will give it.
- Put every receipt and invoice into categories that mirror the scope: roof, windows, drywall, tile, and so on.
- Mark each category covered or not covered. Upgrades, additions and anything the adjuster excluded go in the second bucket and stay there.
- Total the covered categories. That is your cost incurred on covered work.
- Subtract every carrier payment, including the first draft and any supplements.
- What is left is the shortfall you can defend, line by line, with paper behind each one.
If you are doing this in a spreadsheet, the hard part is not the maths — it is keeping the receipts attached to the lines so that when somebody asks "what is this $8,400?", you can answer in one click rather than going through a shoebox. That is precisely what the claim file in Punchlist360 is for.
Then ask for a supplement, not an argument
A supplement is a formal request to revisit the scope because the repair turned out to involve more than the original estimate allowed. It is a routine part of the process, not a complaint. Supplements succeed when they are specific:
- Name the line. "Item 42, drywall, allows 1,200 square feet. The actual replaced area is 1,860 square feet."
- Attach the evidence. Photographs taken before the work was covered up, and the invoice.
- State the number. Not "this is not enough" but "this line is short by $3,140."
- Send it as one packet, not as a series of emails, so it can be assessed in one sitting.
What to do if it stalls
Most policies contain an appraisal clause: each side appoints an appraiser, and if the two disagree an umpire decides. It is faster and cheaper than litigation and it exists precisely for disputes about amount rather than coverage. A public adjuster works for you rather than the carrier and typically takes a percentage — worth considering on a large claim, less so on a small one. Read the honest comparison before you sign anything.
Whichever route you take, the packet you assembled above is the thing that carries the argument. Nobody wins a claim by being annoyed. They win by producing the document nobody can pick apart.
Common questions
How do I calculate my insurance claim shortfall?
Total what you have spent on work the policy covers, then subtract every payment the carrier has made. Exclude upgrades, additions and carrying costs like your mortgage — including them produces a much larger number that an adjuster can dismiss.
Can I ask for more money after I have already been paid?
Yes. It is called a supplement, and it is a normal part of the process. It works best when you name the specific line item, state the exact shortfall, and attach photographs and invoices.
What if the carrier will not move?
Most policies have an appraisal clause: each side appoints an appraiser and an umpire settles the difference. It is designed for disputes about the amount rather than about whether something is covered.
