Door Flood Protection
Door Flood Barriers Engineered for Florida Storms
Doors are the first place floodwater enters a home. Emerald Green installs custom aluminum plank flood barriers for front doors, sliding glass doors, patio doors, French doors, and garage entries across Southwest Florida and the United States Virgin Islands.
When a hurricane pushes storm surge inland or heavy rain overwhelms a property, water finds the lowest opening first. That is almost always a door. Standard weatherstripping is built for rain runoff, not for the standing water and wave action that follow a Florida storm. A purpose-built door flood barrier is what actually keeps water out. Emerald Green is a licensed Florida contractor specializing in removable aluminum plank flood barriers. Our systems are custom-engineered to the exact dimensions of each opening, code-compliant, and rated for the water depths the Gulf Coast and the Caribbean see in real storms. Every install is performed by our own team, not subcontracted.
Flood Barriers Built for Every Door on Your Home
Not every door is the same. A front entry, a sliding glass lanai door, and a garage service door each face floodwater differently. We custom-fit aluminum plank barriers to the opening type and the threat profile of the property.
Front and Entry Doors
The most common entry point for floodwater. We design barriers that mount cleanly to the door frame or surround, stack from the ground up, and seal flush against the threshold and jambs.
Sliding Glass and Patio Doors
Wide multi-panel sliders are uniquely vulnerable because their tracks sit low and span long distances. Our barriers span openings up to commercial widths with intermediate posts where engineering requires them.
French Doors and Double Doors
Pairs of swing doors need barriers that account for both panels and the center seal. We engineer the system so the planks distribute load evenly across both openings.
Garage Entry and Service Doors
Garages are a frequent flood path because their floors typically sit lower than the main house. We coordinate door barriers with full garage door protection so water cannot route around the system.
Side and Rear Service Doors
Mudroom doors, laundry doors, and pool equipment access doors are easy to overlook and easy for water to exploit. We protect every penetration that sits below the modeled flood elevation.
Commercial Storefront Doors
Restaurants, retail, and offices in Southwest Florida rely on storefront entries that flood barriers must protect without disrupting daily operations. Our commercial installs mount discreetly and deploy in minutes.
How Emerald Green Door Flood Barriers Actually Work
The system has two parts. A set of fixed-mount channels installs permanently into the structure on either side of the door opening. The mounts are discreet, powder-coated, and stay in place year-round without affecting how the door looks or operates. When a storm is forecast, marine-grade aluminum planks slide into the channels and stack one on top of the next. The planks seal against compression gaskets that run the full length of every contact surface. Once installed, the barrier holds back water through compression and engineered structural strength, not air pressure. The full barrier deploys in minutes per opening. After the storm, the planks come down and store flat. The mounts stay. That means the protection is ready every season without a service call.
Why Removable Aluminum Plank Barriers Outperform Inflatable Systems
Shopping for removable flood barriers for doors usually surfaces two options. Inflatable bladders and removable aluminum plank systems. They are not equivalent. Inflatable barriers rely on continuous internal air pressure to hold their shape. They are inexpensive and quick to deploy, but they are also vulnerable to puncture from wind-driven debris, they lose effectiveness if pressure drops, and they were not designed for the wave action and prolonged inundation that hurricane storm surge produces. Aluminum plank barriers are built for the threat profile Florida homes actually face. They are rated for repeated deployment, they handle debris impact, and they keep water out for the duration of a storm event, not just the first few hours. They cost more upfront and they last decades. For coastal and storm-prone properties, the math is straightforward.
Our Process
From Consultation to Protected
Every install follows the same four-phase process so nothing is missed and the system performs when the storm arrives.
-
Step 1
On-Site Consultation
We meet at the property, walk every door, measure each opening, and identify the threat profile based on flood elevation, surge modeling, and the structure itself.
-
Step 2
Custom Engineering
We engineer a system specific to your home or building. Every plank, mount, gasket, and post is sized to the opening and the water depth we need to hold back.
-
Step 3
Professional Installation
Our team mounts the permanent hardware, confirms a watertight seal on every opening, and walks you through deployment so you can install the planks yourself when a storm is forecast.
-
Step 4
Storm-Season Ready
Your barriers are ready every season. If you are in our Concierge Storm Program, we handle deployment for you when a named storm threatens.

Frequently Asked
Questions, Answered
Are door flood barriers removable?
Yes. The aluminum plank flood barriers Emerald Green installs are fully removable. The mounting hardware stays permanently in place around the door frame, and the planks themselves stack into place in minutes when a storm is forecast. After the threat passes, you remove the planks and store them. Your doors look and function normally between events.
Do flood barriers work for sliding glass doors and patio doors?
They do. Sliding glass doors and patio doors are some of the most vulnerable openings on a home because their tracks sit close to ground level. Emerald Green custom-fits aluminum plank barriers to span the full width of sliding door openings, including the wide multi-panel configurations common on Florida lanais.
How much do flood barriers for doors cost?
Pricing depends on the door width, the height of protection required, and the number of openings being protected. Most single-door installations land in the low-to-mid four figures. Multi-opening systems for a full home are quoted after an on-site consultation. Every Emerald Green proposal is fixed-price with no surprises.
What is the difference between aluminum plank and inflatable flood barriers?
Aluminum plank barriers seal against permanently installed mounts and rely on engineering, not air pressure, to hold back water. They handle wave action, debris impact, and prolonged inundation. Inflatable barriers depend on continuous air pressure, are vulnerable to puncture from storm debris, and are not designed for the hurricane-driven storm surge Florida homes face.
How long does installation take?
Most door installations are completed in one to two days per home. Custom fabrication of the planks happens before the install day, so the on-site work is focused on mounting hardware and confirming a watertight seal. Larger multi-opening projects can run longer.
How do I stop water from coming under my door during a storm?
Weatherstripping and sandbags are short-term fixes that almost always fail under hurricane conditions. The reliable solution is a properly engineered flood barrier system that mounts to the structure itself and seals the entire opening, not just the gap under the door. Emerald Green designs and installs systems rated for the water depths Southwest Florida actually sees.
