Claims playbook

Prepare · File · Follow up

Start here

  • Photograph chip or crack and note date, location, and whether damage is spreading.
  • Check if comprehensive coverage applies and whether your state or policy waives glass deductibles.
  • Use carrier-approved glass vendors when required—OEM vs aftermarket glass may affect approval.

Workflow

Claim steps

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

  1. 1

    Photograph chip or crack and note date, location, and whether damage is spreading.

  2. 2

    Check if comprehensive coverage applies and whether your state or policy waives glass deductibles.

  3. 3

    Use carrier-approved glass vendors when required—OEM vs aftermarket glass may affect approval.

  4. 4

    For repairs under size limits, ask if repair (not replacement) is covered at $0 deductible.

  5. 5

    If replacing windshield with ADAS cameras, confirm calibration is included in the claim scope.

  6. 6

    Keep rental needs separate—glass claims rarely include rental reimbursement.

Preparation

Document checklist

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

  • Photos of damage and VIN
  • Repair shop or mobile glass estimate
  • Policy declarations showing comprehensive deductible
  • ADAS calibration invoice if applicable
  • Prior glass claim history if carrier asks
  • Police report only if vandalism-related

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.

Only liability coverage on policy

Glass falls under comprehensive—liability-only policies do not cover windshield damage.

Wear and pitting excluded

Old sand-pitted glass may be denied as maintenance—not sudden comprehensive loss.

Non-approved installer

Some carriers require network shops for warranty—out-of-network may reduce payment.

Deductible applies

In states without glass waiver, comprehensive deductible reduces net payment.

Timeline

What slows a claim down

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

ADAS recalibration scheduling

Windshield replacement on newer cars may need dealer calibration—adds days.

OEM parts approval

Insurer may offer aftermarket glass first—negotiate if lease requires OEM.

Chip vs crack size rules

Small chips may be repairable immediately; large cracks need full replacement approval.

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.

  1. 1Request written denial citing comprehensive exclusion before paying out of pocket.

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 delay repair—spreading cracks may be deemed worsening after initial notice.
  • Ask if $0 deductible repair applies to chip size under carrier limits.
  • Keep ADAS calibration line items separate on the invoice.
