Quick Answer

TWIA is the state’s wind and hail insurer of last resort for the 14 first-tier coastal counties plus a portion of Harris County. You generally have one year to file a claim; TWIA generally has 60 days to accept or reject after receiving requested items and 10 days to pay an accepted claim. Disputes about the amount are resolved through appraisal or mediation — lawsuits are attorney work.

Who Does TWIA Cover?

The Texas Windstorm Insurance Association was created so coastal policyholders who cannot find windstorm and hail coverage in the voluntary market still have a place to turn. Per twia.org, eligibility covers the 14 designated first-tier coastal counties below, plus part of Harris County.

Aransas
Brazoria
Calhoun
Cameron
Chambers
Galveston
Jefferson
Kenedy
Kleberg
Matagorda
Nueces
Refugio
San Patricio
Willacy

Harris County (partial): TWIA reports that the covered portion of Harris County is inside the city limits and east of Highway 146 — including La Porte, Morgan’s Point, Pasadena, Seabrook, and Shore Acres. Eligibility is property-specific, so confirm your address with TWIA.

Filing a TWIA Claim: The Timeline

Once a windstorm or hailstorm hits, TWIA runs on its own claim clock. These are the general windows TWIA publishes; the exact dates that apply to your loss can vary.

1 year

File within the deadline

TWIA generally allows one year from the date of loss to file a windstorm or hail claim. Filing promptly with photos, a description of the damage, and your policy number gets the clock started.

60 days

TWIA investigates & decides

After receiving all the information it reasonably requests, TWIA generally has 60 days to investigate and notify you in writing whether it accepts or rejects the claim (twia.org/claims).

10 days

Payment on accepted claims

Once TWIA accepts a claim and you have provided all requested materials, it generally has 10 days to issue payment, less any applicable deductible and depreciation.

A TWIA policy applies a separate windstorm/named-storm deductible, frequently set as a percentage of your dwelling or building coverage rather than a flat amount. Model the math with our hurricane deductible calculator.

Disagree With TWIA? How Appeals Work

Appraisal

Appraisal is a formal process for disputes about the amount TWIA will pay. You generally have 60 days from the date of TWIA’s claim acceptance/assessment letter to demand appraisal. Each side names an appraiser, the two appraisers select an umpire, and the umpire rules on disagreements. The result is binding on the amount of the loss. You pay your own appraiser and half of the umpire’s fee (twia.org/claims).

Alternative Dispute Resolution (ADR)

Mediation is the primary form of alternative dispute resolution TWIA uses. Under its rules, ADR is generally completed within 60 days after a party requests it, unless extended, and the parties share the costs equally.

TDI complaints

If you believe TWIA mishandled your claim, the Texas Department of Insurance (TDI) accepts complaints and can help you understand the process (tdi.texas.gov). Lawsuits and bad-faith claims are legal matters handled by a licensed attorney — not a public adjuster.

How a Public Adjuster Can Help on a TWIA Claim

Inspect and fully document coastal wind and hail damage — roof, exterior envelope, water intrusion, and interior consequences.

Prepare a detailed, line-item repair estimate and read your policy in the ordinary course of adjusting (coverage, exclusions, endorsements, and the windstorm deductible).

Present the claim and supporting evidence to TWIA and negotiate the amount of the loss on your behalf.

Help you weigh whether to demand appraisal when the dispute is about the dollar amount of the damage.

Under Tex. Ins. Code §4102.104, a public adjuster’s total commission may not exceed 10% of the settlement. A public adjuster handles the valuation and documentation of the claim; legal disputes, demand letters, Chapter 542A pre-suit notices, and litigation are work for a licensed attorney, which DCS does not provide.

Frequently Asked Questions

What is TWIA and who does it cover?
The Texas Windstorm Insurance Association (TWIA) is the state’s wind and hail insurer of last resort. It provides windstorm and hail coverage to eligible policyholders in the 14 designated first-tier coastal counties — Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Refugio, San Patricio, and Willacy — plus a portion of Harris County. Per TWIA, the covered part of Harris County is inside the city limits and east of Highway 146, including La Porte, Morgan’s Point, Pasadena, Seabrook, and Shore Acres (twia.org).
How long do I have to file a TWIA windstorm claim?
TWIA generally allows one year from the date of loss to file a windstorm or hail claim. After TWIA receives all the information it reasonably requests, it generally has 60 days to investigate and notify you whether the claim is accepted or rejected, and 10 days to pay an accepted claim once you have provided all requested materials (twia.org/claims). Confirm the exact deadlines that apply to your policy.
How does a TWIA windstorm deductible work?
TWIA policies apply a windstorm and hail deductible, which is often stated as a percentage of the dwelling or building coverage rather than a flat dollar amount. The deductible (and any applicable depreciation) is subtracted from the covered loss before payment. Because percentage deductibles can be large on coastal property, it helps to estimate yours — our hurricane deductible calculator can model the math.
How do I dispute a TWIA claim decision?
For disagreements about the amount of the loss, TWIA offers appraisal — you generally have 60 days from the acceptance/assessment letter to demand it. TWIA also uses mediation as alternative dispute resolution, and the Texas Department of Insurance accepts complaints. Appraisal and ADR address the dollar amount of the claim; lawsuits and bad-faith disputes are legal matters for a licensed attorney.
Can a public adjuster help with a TWIA claim?
Yes. A licensed Texas public adjuster can inspect the damage, document the loss, prepare a detailed estimate, apply your policy and deductible, and negotiate the claim amount with TWIA on your behalf. Under Texas Insurance Code §4102.104 a public adjuster’s total commission may not exceed 10% of the settlement. A public adjuster does not practice law or file lawsuits — those are handled by an attorney.
