How Much Does Property Insurance Cost in Sint Maarten? 2026 Windstorm & Flood Coverage Guide
Property insurance on Sint Maarten isn’t optional in practice — most Dutch-side mortgage lenders won’t close a loan without proof of windstorm coverage in place, so foreign mortgage buyers should be pricing this before they make an offer, not after. - Premiums are driven by construction type, roof age, elevation, and distance from the coastline far more than by the purchase price of the home. - “Windstorm” and “flood” are usually separate line items, sometimes from separate insurers, and a policy that covers one doesn’t automatically cover the other. - Reinsurance costs across the Caribbean basin have been rising, which means renewal premiums can climb even if nothing about your property changed. - The cheapest policy on paper is often the one with the highest named-storm deductible — read that number before you compare premiums.
If you’ve spent any time researching what it actually costs to own here, you’ve probably already read our breakdown of the full cost of owning property in Sint Maarten and the annual property tax guide. Insurance is usually the line item that surprises buyers most, because it doesn’t behave like insurance back home. This guide walks through what drives the number, what “windstorm” and “flood” actually mean here, and how to avoid finding out your coverage had a gap the week a storm is forecast.

Why Sint Maarten insurance doesn’t price like a US or Canadian policy
Sint Maarten sits in an active hurricane corridor, and insurers underwriting property here are pricing against a real, recent loss history — Hurricane Irma in 2017 reset how the local and regional insurance market prices risk, and premiums have not gone back down. Most insurers writing on the island are either local branches of regional Caribbean carriers or specialty lines placed through Lloyd’s-linked brokers, and they lean heavily on engineering data: roof type, tie-down construction, hurricane shutters or impact windows, elevation above sea level, and proximity to the shoreline.
That’s a different rating model than a standard homeowners policy in the US, where premium is mostly a function of home value and claims history. Here, two homes of identical value can carry very different premiums depending on whether one is a concrete-and-rebar build set back from the water and the other is a wood-frame structure on a beachfront lot.
Wei’s take:
I’ve had clients fall in love with a house, only to get an insurance quote back that changes the math on the whole purchase. Get a windstorm quote before you’re under contract, not during due diligence — it’s a five-minute ask that can save you from a deal that doesn’t actually work.
What drives your premium
- Construction type and roof age. Concrete block or poured concrete with a properly tied-down roof rates lower than wood frame or an older roof past its rated lifespan.
- Elevation and coastal proximity. Properties closer to sea level and closer to the water carry higher flood and storm-surge loadings than hillside homes in areas like Beacon Hill or Belair.
- Hurricane mitigation features. Impact-rated windows, storm shutters, and reinforced garage doors can meaningfully reduce your windstorm premium — ask your insurer for the specific credit before you assume it applies.
- Rebuild cost, not purchase price. Your insurer prices to the cost of rebuilding the structure, which on an island where most materials are imported is often higher per square foot than what you paid.
- Claims and vacancy history. A property with prior storm claims, or one that will sit vacant for long stretches as a seasonal home, can carry a loading — which matters if you’re weighing this as a rental property versus a full-time residence.
Windstorm coverage: what it actually pays for
Windstorm insurance covers wind damage from named storms and hurricanes — roof loss, structural damage from wind pressure, and damage from wind-driven debris. It typically does not cover flooding, storm surge, or water that enters through the ground rather than through wind-created openings in the structure. That distinction trips people up every hurricane season: a homeowner assumes “I have hurricane insurance” means “I have flood insurance,” and finds out otherwise when the claim is filed.
Windstorm policies on Sint Maarten commonly carry a named-storm deductible expressed as a percentage of the insured value — often somewhere in the 2%–5% range, applied specifically to hurricane and named-storm claims, separate from your regular deductible on other damage. On a home insured for $500,000, a 3% named-storm deductible means the first $15,000 of a hurricane claim comes out of your pocket before the policy pays anything. This is the number buyers skip past when they’re comparing premiums, and it’s the one that matters most the week you actually file a claim.
Flood coverage: usually a separate policy
Flood coverage on Sint Maarten is typically underwritten and priced separately from windstorm, sometimes through a different insurer entirely. It covers water intrusion from storm surge, heavy rainfall runoff, and rising water — the kind of damage that hits low-lying areas like parts of Simpson Bay and Cole Bay hardest during heavy-rain events, not just named storms.
If a lender is financing your purchase, ask explicitly whether they require flood coverage in addition to windstorm — Dutch-bank lenders underwriting through the requirements outlined in our Dutch bank mortgage guide for American buyers and Canadian mortgage financing guide will sometimes require both as a condition of closing, and that requirement should be priced into your budget from the start, not discovered at the closing table alongside your notary fees and closing costs.
What a realistic annual premium range looks like
Every quote is property-specific, and I’d rather send you to a licensed broker for a real number than guess at one — but as a planning range, buyers budgeting for a mid-size concrete-construction home or condo in a well-built development should expect combined windstorm and property premiums to run from roughly 1%–3% of the insured rebuild value per year, with older wood-frame structures, oceanfront exposure, or thin flood coverage pushing toward the higher end. That’s a meaningfully larger annual line item than most buyers coming from the US mainland are used to, and it belongs in the same spreadsheet as your property tax estimate and ongoing ownership costs before you make an offer.
Red flags to watch for when comparing quotes
- A quote that’s dramatically cheaper than the others — check the named-storm deductible and confirm exactly what perils are excluded before assuming it’s a better deal.
- No mention of flood coverage at all — silence on flood usually means it isn’t included, not that it’s automatically bundled in.
- A policy written on “actual cash value” instead of “replacement cost” — actual cash value pays out depreciated value after a loss, which on an aging roof can leave a real gap between the payout and what it costs to rebuild.
- Coverage that lapses on a strict calendar date rather than renewing automatically — if you’re managing the property remotely, as covered in our guide to managing a vacation rental from abroad, a missed renewal during hurricane season is the worst possible time to discover a gap.
- No confirmation of who holds the policy documents — if you’re buying through an LLC structure, make sure the policy is written to the correct legal owner, not an individual name that no longer matches title.
How this fits into your broader due diligence
Insurance shouldn’t be priced in isolation. It’s one line in the full due diligence checklist I walk every buyer through, alongside title review, long-lease vs. freehold status, and whether title insurance makes sense for your specific transaction. And it connects directly to how seriously you take hurricane season as a buyer — a property’s storm history and construction quality should shape both your offer and your insurance shopping from day one.
Frequently Asked Questions
Does Sint Maarten require homeowners insurance by law? There’s no blanket legal mandate for private homeowners the way there is for auto liability, but in practice any financed purchase will require windstorm (and usually flood) coverage as a lender condition, and most strata/HOA-managed buildings require unit owners to carry it as part of the association agreement.
Is windstorm insurance the same as hurricane insurance? Functionally, yes — “windstorm” is the technical policy term for coverage against wind damage from storms and hurricanes. It’s the piece that pays for roof and structural wind damage; it’s not the piece that pays for flooding.
Can I get flood and windstorm coverage from one insurer? Sometimes, but not always — several buyers end up with windstorm through one carrier and flood through another. Confirm this explicitly with your broker rather than assuming one policy covers both perils.
Does insurance cost more on the water than on a hillside? Generally yes. Coastal and low-elevation properties carry higher flood and storm-surge exposure than hillside homes in areas like Beacon Hill, and that shows up directly in the quote.
What’s the single biggest mistake buyers make with insurance here? Not getting a quote until after they’re under contract. Get the number early — it can change what you’re willing to offer, and it belongs in the same conversation as your closing costs and financing.
