Filing a commercial property insurance claim means notifying your carrier of the loss, protecting the property from further damage, documenting what was damaged, and supporting the repair cost with a detailed estimate. The carrier assigns an adjuster, reviews coverage and pays according to the policy. Most delays come from late notice, thin documentation or estimates that do not match.

1. Make the property safe and stop the damage

Life safety comes first. Then stop the source: shut off water, secure openings, tarp roofs and board up windows. Most policies require the insured to take reasonable steps to protect the property from further damage, and the cost of those emergency steps is typically part of the claim. Keep receipts and photos of everything done.

2. Notify the carrier promptly

Report the loss to your carrier or broker as soon as possible. Policies require prompt notice, and some set specific deadlines for notice or for a sworn proof of loss. Have the policy number, date and cause of loss, and a first description of the damage ready. You will be assigned a claim number and an adjuster.

3. Document before and during cleanup

Photograph and video the damage before anything is removed, room by room and from the outside. Keep samples of damaged materials where practical until the adjuster has seen them. For water losses, moisture readings and drying logs show why materials were removed; for storm losses, dated photos of the roof and exterior tie the damage to the event.

4. Get a line-item estimate

The adjuster will write an estimate, and you should have your own from the contractor who will do the work. Carriers commonly use Xactimate, so an estimate in that format, with quantities, unit prices and code-required items listed separately, is easier to reconcile line by line. A lump-sum number is hard to defend and slow to approve.

5. Understand ACV, RCV and depreciation

Many commercial policies pay on a replacement cost value (RCV) basis but first issue payment at actual cash value (ACV), which is replacement cost minus depreciation. The withheld depreciation is typically released after the repairs are completed and documented. Your deductible, and any separate wind, hail or named-storm deductible, is applied to the payment.

6. Plan for code upgrades and supplements

Repairs can trigger current building codes that the original building did not meet. Coverage for that work depends on the policy’s ordinance or law provisions, so identify code items early. Hidden damage found once walls or roofs are opened is submitted as a supplement, with photos and quantities, before the added work is done where possible.

7. Keep one set of records to closeout

Keep invoices, change documentation, photos of completed work and the final estimate together. They support the release of withheld depreciation and close the claim cleanly.

Where Apex fits

Apex stabilizes the property, documents the damage, and prepares a line-item estimate in the format carriers use, then builds the scope it priced. We work directly with adjusters on scope and pricing. Coverage decisions are between you and your carrier; if you want an advocate on coverage, you can retain a licensed public adjuster or counsel.

FAQ

Common questions

What is the first thing to do after commercial property damage?
Make the property safe and stop further damage: shut off water, secure openings, tarp the roof or board up windows. Then notify your carrier promptly and start documenting with photos and video before cleanup. Most policies require reasonable steps to protect the property, and emergency costs are usually part of the claim.
What is the difference between ACV and RCV?
Actual cash value (ACV) is the cost to replace damaged property minus depreciation. Replacement cost value (RCV) is the full cost to replace it. Many commercial policies pay RCV but issue ACV first, releasing the withheld depreciation after repairs are completed and documented. Your policy terms decide how this works.
What format should a contractor estimate be in?
Carriers commonly use Xactimate, so a line-item estimate in that format, with quantities, unit prices and code-required items shown separately, is easiest for an adjuster to reconcile. A lump-sum estimate is harder to review and slower to approve. Apex prepares line-item estimates in the format adjusters use.
What is a supplement on an insurance claim?
A supplement is a request for additional payment when damage is found that was not in the original estimate, such as rot or water damage revealed after walls or roofing are opened. It should be supported with photos, measurements and line items, and submitted before the added work is done where possible.
