FLOOD PANELS FOR HOMES. MEASURED. BUILT. SEALED.
Custom aluminum flood panels measured to every opening on your home, fabricated in our own shop in St. Petersburg and installed by our own crew. Rated to hold back up to 10 feet of water.
Most flood panels are one-size sheets with foam edges. Ours are cut to your exact openings, lock into mounted channels and seal with compression gaskets, built to stand up to storm surge, not just rain.

A wall that goes up only when the water does.
A flood panel system has three parts: aluminum channels mounted on each side of an opening, panels that stack into those channels when a storm is coming, and gaskets that seal each panel to the next, to the channels and to the floor.
The channels stay on the house year round, flush and out of the way. The panels store flat until a storm is named. When it is, they slide in, stack to the height you need and seal the opening from side to side.
That is the difference between flood panels and plywood or sandbags. Plywood was never built to hold water back, and sandbags leak by design. Panels are measured once and go back up every storm.

of water our barriers are rated to hold back
Compare that to a sandbag line or a stick-on door dam. Those slow water down. They are not built for surge.
starting price per opening
Every opening is a different size, so every quote is itemized. The free assessment gives you an exact number, and flexible financing is available.
One system for every opening on the house.
Water does not pick one door. Here is where flood panels go and how each one is built.
Doors and sliders
Entry doors, French doors and lanai sliders each get panels cut to their exact width and height, sealed at the threshold and the sides.
Garages and wide openings
Two-car garages and wide sliders get a removable center post or brace set into the floor, so the panels stay rigid against moving water.
Storefronts and commercial
Flood panels protect business entrances too. Same channels and gaskets, measured to the storefront.
The 50% rule
After a flood, Florida’s 50% rule decides whether you can repair or must rebuild to current code. Keeping water out keeps damage below that line. How the 50% rule works.

This is what it looks like when a storm is named.
The channels are already mounted on your house, flush and out of the way. When a storm is coming, the panels slide in, stack and seal. Garage, front door, sliders onto the lanai, every opening that faces the water.
Every panel is labeled for its spot, so anyone in the house can put the panels up. Our crew walks you through it at install, so you have done it before the first storm.

Water is not picky. It comes through the front door, the garage, the sliders, the vents and the sewer line, sometimes all at once. Sealing one opening and leaving the rest is how houses still flood with barriers up.
Flood Barriers for Home
Custom panels measured to every opening on the house, not a one-size kit.
Door Flood Barriers
The threshold gap under every exterior door, sealed below the water line.
Garage Door Barriers
The widest and lowest opening you have, and usually the first one to let go.
Sliding Door Barriers
Lanai and pool deck sliders, where the track weep holes start running backwards.
Backflow Prevention
The drains. Barriers work above ground, this handles the line underneath it.
Flood Vent Covers
Foundation vents and utility penetrations, the openings nobody counts.
One free assessment maps every opening above ground and the sewer line below it, and puts all of it in a single plan.
From the call to a protected house.
Free assessment
We come to you, walk the property, and give you a straight answer on which openings actually need protection and which do not.
Exact measurement
Every door, slider and garage opening measured to the millimeter. Your system fits your house and nobody else’s.
Built in our factory
Panels cut, welded and gasketed by our own people. No dealer network, no shipped kit, no subcontractor with a box.
Install and walkthrough
We mount the channels, fit every panel, and put you through one practice deployment so you are not learning it in the rain.
Ready when it matters
Most homes deploy in about an hour. Prefer hands off? We offer storage and deployment service too.
Built heavier, sealed tighter, made in Florida.
2.5X thicker. Sealed under pressure.
Aluminum profiles roughly 2.5 times the thickness of most competing products, paired with larger, age-resistant dual-phase EPDM compression gaskets that seal tighter as water pushes against them. Rated to hold back up to 10 feet of water.
We build it. We install it. Nobody else touches your house.
Our founders’ own homes flooded, which is the reason this company exists. Every system is assessed, fabricated and installed in house. The people who measured your openings are the people who mount the channels.

Reinforced cross sections, deeper channels, solid cast stainless hardware and dual-phase EPDM gaskets. Put ours next to anything else on the market and the difference is visible.
You will forget it is there until you need it.
Your doors still work
The channels mount beside each opening. Your doors, sliders and garage open and close like normal the rest of the year.
Up fast when a storm is named
Panels slide into the channels and stack. Every one is labeled for its position.
Stores flat
When the storm passes, the panels come down and store flat on a shelf or against a wall.
Our crew, not a subcontractor
We fabricate in St. Petersburg and our own team does the measuring and the install. No middleman.
Measured to the opening. Built to seal.



What homeowners say after the install.
After our home flooded from storm surge, we decided to install flood barriers. Dam It Defense installed them at all our garage and door entryways, and they store and deploy them for us when hurricanes threaten. They answered all of our needs. The product is well constructed and heavy duty.
Lee was very informative about the system. The panels are light enough that anyone can install them, and they provided extra pieces and even offered to move the sliding system once my patio is finished. The company has been easy to work with. I have peace of mind if another hurricane comes. Would recommend this company!
We feel very fortunate to have found Dam It Defense. The pricing was lower than any other company and the product far superior. The install team led by Andrea was thorough, professional, and did an amazing job. Everyone from the owners to the installers was knowledgeable and incredibly service oriented. It was a no brainer to go with them.
I reached out to Dam It Defense and Lee came out the very next day, on time as scheduled. He went over the process, showed us samples of the panels, and measured all the entry points. He was extremely personable and patiently addressed every concern and question we had. It really put us at ease.
Don’t just take our word for it.
Our founders’ own homes flooded. They built the company local news has covered ever since.
Their homes were both flooded by Hurricane Helene, so they built a flood prevention system with sturdy aluminum and modular height options.Read the story
A pair of St. Petersburg flood victims opened Dam It Defense to provide residential flood barriers after Hurricane Helene impacted their homes.Read the story
The company opened its first factory in St. Petersburg’s Warehouse Arts District a year after Helene, with family and community atop the founders’ priorities.Read the story
Dam It Defense launched in 2025, sold several hundred systems, and grew into a local team of nearly 20 employees.Read the story
Flood panels: common questions.
What are flood panels?
Flood panels are removable aluminum barriers that slide into channels mounted on each side of a door, slider, garage or other opening. When a storm is coming, the panels stack and seal across the opening to keep floodwater out. The rest of the year, the channels sit flush and the panels store flat.
Are flood panels better than plywood or sandbags?
Plywood is not sealed and was never built to hold back water, and sandbags leak by design. Flood panels are measured to the opening, sealed with compression gaskets and rated to hold back up to 10 feet of water. They go back up every storm instead of being rebuilt.
Can flood panels protect sliding glass doors and garages?
Yes. Sliders and garages are some of the most common openings we protect. Wide spans get a removable center post or brace set into the floor, so the panels stay rigid against moving water.
How much do flood panels cost?
Systems start at $499 per opening. Larger openings like garages and wide sliders cost more because of their size. The free assessment gives you an exact, itemized quote, and flexible financing is available.
How long does it take to put flood panels up?
Most homes deploy in about an hour. Every panel is labeled for its spot, and our crew walks you through it at install. Prefer hands off? We offer storage and deployment service too.
Where do you install flood panels?
We build in St. Petersburg and install across Tampa Bay and the Gulf Coast, from Tampa and Clearwater to Sarasota, Fort Myers and Naples.
