The #1 Entry Point Floodwater Uses to Destroy Gulf Coast Homes. It's Not What You Think.

You've covered your windows. You've reinforced your garage door. You think your home is ready for storm season. But there's one entry point that almost every Gulf Coast homeowner overlooks — and it's responsible for some of the most devastating flood damage on record.

The Weak Point Nobody Talks About

Ask most Gulf Coast homeowners what they do to prepare for hurricane season and you'll hear the same answers: impact windows, storm shutters, a reinforced garage door. These are all smart investments. But they share a common blind spot.

None of them protect your sliding glass doors — and more specifically, none of them address what happens at the track level when floodwater rises.

Sliding glass door tracks are engineered to handle rain. They are not engineered to handle storm surge, flash flooding, or even a few inches of standing water. The moment water levels rise past the track threshold, water intrudes — fast, silently, and destructively.

Why Sliding Glass Doors Fail in a Flood

1. Water levels rise at the base of the door.
   Storm surge, flash flooding, or heavy rainfall runoff pools against the exterior of your sliding glass door. Standard weatherstripping begins to fail almost immediately.
2. The track channel fills.
   Sliding glass doors sit in a track channel at the base. This channel has a drainage design for rain — not for sustained water pressure. It fills within seconds.
3. Water intrudes into your home.
   Once the track fills, water has a direct path into your living space. By the time you see it, it's already soaking into flooring, baseboards, drywall, and furniture.
4. The damage compounds quickly.
   Mold begins developing within 24–48 hours. Hardwood floors warp. Drywall crumbles. What started as a few inches of water becomes a months-long remediation project.

Note: Hurricane shutters cover the glass — not the track. Even with shutters fully deployed, the door track at the base of your sliding glass door remains completely exposed to rising water.

The Real Cost of Getting It Wrong

FEMA's data on residential flood damage is consistent and sobering: just 6 inches of water causes an average of $35,000 in residential damage.

On the Gulf Coast, storm surge and flash flooding routinely produce far more than six inches — sometimes in a matter of hours.

StormArmour costs $585. One-time. Reusable every storm season.

The math is not complicated. The decision should not be either.

What Gulf Coast Homeowners Get Wrong About Flood Prep

Most people approach storm prep as a checklist: shutters, check. Garage door, check. Generator, check. The sliding glass door never makes the list — because nobody talks about it, and because the failure mode is invisible until it's catastrophic.

The three most common mistakes:

• Assuming shutters cover the track. They don't. Shutters protect against wind and debris, not rising water at the base of the door.
• Waiting for a named storm to act. Flash flooding — the most common cause of residential flood damage on the Gulf Coast — doesn't require a hurricane. Heavy rainfall events happen every season.
• Relying on towels or sandbags at the last minute. These delay water intrusion by minutes, not hours. They are not a substitute for a purpose-built barrier.

"StormArmour gives homeowners real protection when it matters most."

How StormArmour Solves It

StormArmour is the only barrier engineered specifically for sliding glass door water intrusion. It creates a watertight seal at the track level — the exact point where standard hurricane protection ends and vulnerability begins.

• Blocks up to 99% of water intrusion through sliding glass door tracks
• Installs in minutes with no tools and no contractor
• Miami-Dade NOA approved — the most rigorous hurricane-product certification in the U.S.
• Reusable every season — deploy before a storm, store after
• $585 — versus $35,000 in average flood damage

Your windows are protected. Your garage door is protected. Now protect your sliding glass doors.

Frequently Asked Questions

Do I need StormArmour if I already have hurricane shutters?
Yes. Shutters cover the glass and protect against wind and debris. They do not seal the door track at the base. StormArmour addresses that gap specifically — the entry point shutters leave completely unprotected.

How much water can StormArmour hold back?
StormArmour blocks up to 99% of water intrusion through sliding glass door tracks. Miami-Dade NOA approved — tested under the most stringent hurricane-product standards in the U.S.

How long does installation take?
Under 10 minutes. No tools required. Deployable even under storm warning conditions.

Can I use it on any sliding glass door?
StormArmour fits the most common residential sliding glass door sizes. Visit stormarmour.com to confirm compatibility before ordering.

Is flood damage covered by standard homeowner's insurance?
No. Standard policies do not cover flood damage — you need a separate NFIP or private flood policy. StormArmour prevents the damage before it happens, regardless of your coverage.

Do I need a new one each season?
No. StormArmour is fully reusable. Deploy before each storm, store between seasons.
