Claims playbook

Prepare · File · Follow up

Start here

Document all damaged electronics and appliances with photos and serial numbers before disposal.
Hire a licensed electrician or HVAC tech to write a cause-of-loss letter linking surge to storm if possible.
Check whether damage is sudden (covered) versus gradual equipment failure (often excluded).

Workflow

Claim steps

Follow these in order from pre-authorization through appeal-ready documentation.

1
Document all damaged electronics and appliances with photos and serial numbers before disposal.
2
Hire a licensed electrician or HVAC tech to write a cause-of-loss letter linking surge to storm if possible.
3
Check whether damage is sudden (covered) versus gradual equipment failure (often excluded).
4
File under dwelling vs personal property depending on hardwired equipment versus plug-in devices.
5
Mitigate further damage—unplug unaffected sensitive equipment after the strike.
6
Keep weather reports or news records for the lightning event date.

Preparation

Document checklist

Gather these before filing to reduce back-and-forth with the adjuster.

Photos of damaged devices and charred outlets
Electrician or technician cause-of-loss report
Repair or replacement estimates per item
Weather service lightning strike data for your address
Home inventory with ages and purchase proof
Policy declarations showing special electronics sub-limits

Risk watchlist

Common reasons claims get denied

These show up most often in adjuster decisions for this claim type. Knowing them in advance usually changes how you document the loss.

Gradual wear or power fluctuation over time

Carriers distinguish single surge events from chronic grid issues—need expert letter.

Electronics sub-limit

Plug-in devices may cap at $1,500 unless scheduled—see /guides/home-scheduled-personal-property-buying-guide.

Excluded power surge without lightning

Some policies require lightning as proximate cause—verify form language.

Unmaintained surge protectors

Failure to use protectors rarely voides claim but may affect adjuster skepticism—document protectors used.

Timeline

What slows a claim down

Most delays come from these causes — often fixable with a single phone call or follow-up email.

Cause-of-loss expert scheduling

Electrician reports take 3–7 days after storms—book early.

Item-by-item valuation disputes

ACV on older TVs reduces payment—provide replacement cost sources.

Multiple peril stacking

Wind opens roof then rain damages gear—separate lightning from ensuing loss.

Escalation

If your claim is denied, delayed, or short-paid

Concrete next steps for readers who hit a wall. Each one is a recognized consumer right or documented escalation path.

Paper trail

Talking to the carrier and your state regulator

How you communicate matters. These notes help you keep a written paper trail and use language carriers and state DOIs recognize.

Do not discard fried electronics until adjuster waives inspection in writing.
Label items by room in the proof of loss spreadsheet.
Whole-home surge protectors may help future insurability—keep install receipts.
