MOST FLOOD PREVENTION COMPANIES DO NOT BUILD ANYTHING.
We engineer it, fabricate it and install it ourselves out of our own Florida factory. One company, one crew, one point of accountability.
Searching flood prevention companies turns up restoration crews, catalog resellers and dealer networks all wearing the same label. What you actually want is a flood protection company that measures your building, builds the panels to fit it, and stands behind the install.
Fabrication queues fill the moment a storm gets named. Earlier is cheaper and faster.
Call 727-344-9962Three kinds of company answer this search.
Type “flood prevention companies” into Google and you get three very different businesses using the same words.
Restoration companies. They arrive after the water is already in the house. Valuable work, and it is cleanup, not prevention. If you are searching before a storm, they are not who you need.
Distributors and resellers. They ship a product somebody else manufactured, in whatever sizes the catalog offers. If your opening is an odd width, or your threshold is an odd material, that is your problem to solve on install day.
Manufacturers who install. One company assesses the property, engineers the system, builds it, and mounts it on the building. When something needs to be right, there is one number to call and nobody to point at.
Dam It Defense is the third kind. Every opening is measured on site, every panel is cut and welded at our own Florida facility, and every install is done by our own crew. We are also homeowners who flooded, which is the reason the company exists at all.
Measures, builds and installs
Most of the category splits those three jobs across three businesses. Every seam between them is a place where fit problems live and nobody is responsible.
The assessment costs nothing
We walk the property, map every opening water can use, and leave you with the plan. You keep it whether or not you ever buy anything from us.
Four questions that sort this category fast.
Ask these of us and of everyone else you are talking to. The answers separate the manufacturers from the middlemen in about a minute.
Who actually builds it?
If the company sells a product somebody else manufactures, they cannot change anything about it when your opening is an odd size. Ask where the panels are made and who welds them.
Who installs it?
A subcontracted install means the people who measured are not the people mounting the channels. That gap is where fit problems come from, and it is where the finger pointing starts.
Is the assessment free?
A company that charges to look at your property before it has earned anything is telling you something about how it sees the relationship. Ours is free and the plan is yours regardless.
Are they local?
Our factory is in St. Petersburg and the founders’ own homes flooded in Hurricane Helene. That is not a marketing line, it is why the company exists. As featured on FOX 13.
A company that sells one part is not a plan.
Water does not pick one opening. Plenty of homes with a barrier on the front door still took water through the garage, the sliders, the sewer line or the flood vents. A real flood prevention service maps all of it in one pass.
Flood Barriers for Home
Custom panels measured to every opening on the house, not a one-size kit.
Garage Door Barriers
The widest opening you have and the first place water gets in.
Door Flood Barriers
Low thresholds that leak long before the street is under water.
Backflow Prevention
When the street system fills, it looks for somewhere to go. Usually your line.
Generator Protection
The one thing you need working after the storm, sitting at ground level.
Commercial Buildings
Storefronts, warehouses, condo and HOA buildings, municipal facilities.
One assessment, one coordinated system, one crew. The property gets protected as a whole rather than one opening at a time.
Five steps, and no handoffs in between.
Free assessment
We walk the property and find every opening water can use, including the ones nobody thinks about until the floor is wet.
Engineered to the opening
Every panel measured to the specific door, garage or slider it protects. Nothing gets ordered off a size chart.
Fabricated in Florida
Cut, welded and gasketed at our own facility. Not shipped in from overseas and not white labeled from another manufacturer.
Installed by our crew
Channels mounted, panels fitted, one practice run so you know exactly what storm day looks like. No subcontractors.
Ready every season after
Deploy in about an hour, store the panels flat, and use the same system every year. Bought once, used for years.
Built heavier, sealed tighter, made in Florida.
2.5X stronger. Better sealed.
Aerospace-grade 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. No dealer network, no shipped kit, no subcontractor showing up with a box and a drill. The people who measured your openings are the people who mount the channels.
View system specifications
Aerospace-grade cross sections, reinforced channel depth, and dual-phase EPDM gaskets. Put ours next to anything else on the market and the structural difference is visible.
The difference shows up on the one day it counts.
Fit is everything
A barrier that is close is a barrier that leaks. Water finds the gap you did not measure, and it does not care how good the product was in the catalog photo.
One inch is not a small number
An inch of water across a ground floor means flooring, baseboards, drywall, and everything that was sitting on the floor. The repair is never the part people budget for.
It happens more than once
Nobody floods once and then never again. A system you deploy in an hour and store flat is built for the second time and the fifth, not just for this season.
Custom takes lead time
Measured, fabricated and installed systems cannot be panic-bought. Queues fill the moment a storm gets a name. The cone is a terrible time to start shopping.
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

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 prevention companies: common questions.
What do flood prevention companies actually do?
The good ones assess the property, find every opening water can enter, then engineer and install a system sized to that specific building. We do all three in house from our St. Petersburg factory.
How do I choose one?
Ask who measures, who builds and who installs. If those are three different companies, nobody owns the fit. Our guide to choosing a flood barrier goes deeper on what to compare.
Is this the same as a flood restoration company?
No. Restoration comes after the water is inside. Prevention happens before the storm. We do prevention only.
Do you cover commercial buildings?
Yes. Storefronts, warehouses, condo and HOA buildings, and municipal facilities. Same engineered systems, sized to the opening. See commercial flood barriers.
What does an assessment cost?
Nothing. We walk the property, map every vulnerable opening and put a plan together at no charge, whether or not you buy anything.
What does a system cost?
It depends on how many openings need protecting, how wide they are, and what the thresholds are made of. Our flood barrier cost guide walks through what drives the number.
