You just closed on a raised cottage in the East End, or you're weighing a condo by the Seawall, and the first quote came back in three pieces. That isn't a mistake. In Galveston, the house, the wind and the water are usually three policies, each with its own rules and deadlines.
The Census Bureau estimates the City of Galveston had 53,636 residents in July 2025. We're Watson Insurance, an independent agency in Friendswood, and this page covers the island city. On the Galveston County mainland? See our Dickinson insurance and League City insurance pages. For the wider region, start with our Houston Bay Area insurance guide.
What does Watson Insurance insure in Galveston?
The short answer: We quote homeowners, windstorm, flood, auto, renters, condo and landlord coverage for island addresses, and we build those policies to fit together so nothing falls between wind and water.
TWIA or private wind
Often a separate policy, with a percentage deductible.
Units and belongings
Your own policy for your things.
Rentals and second homes
The right form when you don't live there.
Is Galveston in TWIA windstorm territory?
The short answer: Yes. All of Galveston County is in TWIA's designated catastrophe area, so many island homes carry wind and hail on a separate TWIA or private wind policy with a percentage deductible.
TWIA's overview page (updated May 27, 2026) lists all 14 first-tier coastal counties, Galveston among them. TWIA's basic requirements:
- A turndown first from at least one private insurer.
- A Certificate of Compliance (WPI-8, WPI-8-E or WPI-8-C) for structures built or altered on or after January 1, 1988.
- Insurable condition, with no unrepaired damage.
TWIA covers wind and hail only, never flood, surge or liability. Put your deductible in dollars: TDI's market overview puts the 2025 preliminary average dwelling limit at $432,800 (viewed October 28, 2026); by our math, 2% of that is about $8,656 per claim. Our wind deductible guide and TWIA and private wind guide go deeper.
What is a WPI-8, and does your island home need one?
The short answer: A WPI-8 is TDI's certificate that construction or repair work met the windstorm code, and on the island it keeps a home eligible for TWIA after a new roof, an addition or major repairs.
TDI's windstorm inspection page (updated May 8, 2026) says most new construction, roof replacements and major repairs in the designated area need an inspection.
- During the work, an appointed Texas licensed engineer or a TDI windstorm inspector checks it, and the certificate is a WPI-8.
- After the work, a Texas licensed professional engineer can inspect it for a WPI-8-E, which TDI warns may cost more.
- Exempt: roof repairs of less than 100 square feet that don't involve decking, painting and other non-structural items, fences, gutters, plumbing and electrical repairs, and replacement glass.
Older homes. TDI's windstorm questions page says structures built before January 1, 1988 are eligible for TWIA under certain conditions, but later re-roofs and additions need their own certificate. Buying? TDI publishes WPI-8s online, or call 800-248-6032, option 3.
What matters most for Galveston home insurance?
The short answer: A dwelling limit that matches what it costs to rebuild an elevated or historic island house, a clear answer on which policy pays for wind, and a flood policy sized to the building.
Rebuild cost, not sale price. Pilings, decks and older materials add cost that online estimators miss. TDI's homeowners guide says most companies require you to insure for at least 80% of replacement cost, and some require 100%.
Historic neighborhoods. The city's historic preservation page lists the East End, Lost Bayou, Strand/Mechanic and Silk Stocking areas and says the city's Landmark Commission reviews new construction, rehabilitation, restoration and demolition. Own there? Ask us about ordinance or law coverage, which can help with the added cost of meeting current building codes when you rebuild after a covered loss.
The 50% rule. The city's flood protection page says repairs or improvements costing 50% or more of a building's market value need permits and an elevation certificate, and the building generally must be brought into compliance. If a flood substantially damages an insured building, NFIP's Increased Cost of Compliance coverage pays up to $30,000 toward meeting those rules; it doesn't fund elective remodels.
Our Galveston County home insurance comparison covers carriers, Ike and roof terms.
Second home, condo or short-term rental on the island?
The short answer: Tell us how the property is used before you buy coverage, because a standard homeowners policy may not fit a weekend house or a place you rent to guests.
The Census Bureau puts the City of Galveston's owner-occupancy rate at 46.2% (2020 to 2024), so more than half of occupied homes are rented. The questions we ask:
- Who lives there? If it isn't you, you may need a dwelling or landlord policy.
- Paying guests? TDI's home-sharing page (updated December 10, 2025) says homeowners insurance probably won't cover it if a guest gets hurt or causes damage, and landlord insurance "may not be appropriate for short-term rentals."
- Licensed? City Ordinance 25-060 (adopted November 13, 2025) requires an annual short-term rental license and a local contact who responds within one hour.
- Condo? Your belongings, and often parts of the interior, need your own policy, and the association's declarations decide where its coverage stops; TWIA's condo contents limit is $374,000 (TDI Order 2026-10103). Ask about loss assessment. See our condo page.
- Renting? TDI's renters tips say your landlord's insurance won't cover your belongings; the average Texas renters policy is about $20 a month. See our renters page.
Do Galveston homes need flood insurance?
The short answer: On the island, almost always, because flood is never on a homeowners or wind policy and surge can come from the Gulf or the bay.
In our review of FEMA's public claims data, about 91% of the city's 11,682 Hurricane Ike flood claims were rated in high-risk A or V zones. The National Hurricane Center's Ike report says the Seawall spared much of the city from Gulf waves, but water rising from Galveston Bay still flooded it.
TWIA ties wind to flood: it requires NFIP flood for V-zone homes built or altered on or after September 1, 2009, where NFIP coverage is available, and newer homes in federal Coastal Barrier Resources units can be shut out of both. If the city's Community Rating System discount applies, FEMA applies it to every NFIP policy in the community; we confirm the current class on every quote.
Our Galveston flood insurance guide covers V zones, the 18-inch elevation rule and NFIP versus private flood.
What should Galveston drivers know about car insurance?
The short answer: Island commutes are short but streets are busy: keep PIP, UM/UIM and comprehensive, and ask before you drive a golf cart on a city street.
Galveston workers average a 20.2-minute commute (Census, 2020 to 2024), against 26.7 for Texas. TxDOT's 2025 crash tables count 1,511 crashes inside city limits; by our math, about 28 per 1,000 residents, against roughly 18 countywide. City counts include visitors and through traffic.
- Golf carts. The city requires registration, a plate, seat belts and inspections for street carts. Your car policy doesn't automatically cover one.
- Keep the protections. TDI's auto guide says PIP and uninsured/underinsured motorist coverage stay on unless you reject them in writing. Comprehensive pays for fire, hail, theft, flood, flying gravel or hitting an animal.
Our Galveston County car insurance comparison covers the causeway, the Bolivar ferry and golf cart law.
How should island owners plan insurance around hurricane season?
The short answer: Fix coverage well before a storm forms, because a new NFIP flood policy generally takes 30 days to start and TWIA won't sell a policy while a hurricane is in the Gulf.
Galveston County's Office of Emergency Management sorts evacuation zones by ZIP code, and its 2025 disaster guide places the island's 77550, 77551 and 77554 in the Coastal Zone. TxDOT's I-45 project page lists better hurricane evacuation among its reasons for widening the island freeway.
- Before June: confirm your wind deductible in dollars, your flood limits and your roof certificate.
- Pack the paperwork: the county guide lists your insurance policy, a home inventory and property photos.
- Cars: surge damage to a car is a comprehensive claim, not a flood-policy claim, so it's covered only if you carry comprehensive.
Our hurricane insurance checklist and guide to sorting wind from flood cover the rest.
How do we serve Galveston from Friendswood?
The short answer: We confirm the address, the use and the building's paperwork, then compare our carriers and the wind and flood markets at identical limits, mostly by phone and email.
Our public carrier lineup for home and auto coverage is Geico, Progressive, Liberty Mutual and Safeco, plus TWIA and private wind and NFIP and private flood. We re-confirm which carriers can write your specific policy before every quote, because appetite and appointments change. We are not appointed with every carrier in Texas.
Every quote uses the same limits, deductibles and endorsements. When we re-shop coverage, clients save on average about $500 a year; your result will depend on your home, cars and record.
Our office is at 2 Parkside Drive, Suite 109, Friendswood, TX 77546, open Monday through Friday, 9:00 AM to 5:30 PM. Email your declarations pages, elevation certificate and any WPI-8s to info@watsoninsure.com or call (832) 703-1289. Got a non-renewal notice? Texas Insurance Code §551.105 requires the insurer to give you at least 60 days' notice before your policy ends; our non-renewal guide covers next steps.
The bottom line
Insuring on Galveston Island means three policies that fit: homeowners at real rebuild cost, wind with a deductible you can afford in dollars, and flood sized to the building. Keep your WPI-8s and elevation certificate, and tell us how the property is used. Mainland neighbors can see our Dickinson and League City pages, or you can start a free quote.
