Where our flood barrier systems are deployed.
Our flood barrier installation process covers the actual geometry and load path of your openings, then deploys as a complete perimeter flood and storm surge protection strategy.
Garage Door Openings
Wide-span custom flood planks, engineered anchors, and reinforced channel depth for high-risk garage elevations.
Front and Side Doors
Compact barrier profiles with precision fit at thresholds and jambs to reduce seep paths at common entry points.
Sliders and Walkouts
Custom channel and compression design for long openings where temporary stacks fail under surge pressure.
Low Mechanical Openings
Integrated barrier planning around vents, utility transitions, and other envelope vulnerabilities near grade.
The Highest Quality Flood Prevention System on the Market.
2.5X Strength and Seal
Our systems use industrial-grade 6061-T6 aluminum profiles that are thicker and denser than many competing products. This is paired with larger, age-resistant dual-phase EPDM compression gaskets for stronger long-term sealing performance.
Every system is designed around your specific opening dimensions, substrate conditions, and deployment requirements. That matters because fit and compression are what determine whether a barrier works when surge pressure rises.
Not all flood barriers are built the same. Our aluminum flood barrier systems use 6061-T6 aluminum cross sections, reinforced channel depth, and dual-phase EPDM compression gaskets engineered to a higher standard than most competing flood protection systems on the market in Tampa Bay and St. Petersburg. When homeowners across Tampa Bay and the Gulf Coast compare flood barriers, the structural difference is visible.
Flood Planks vs Flood Gates: What homeowners should know.
Flood Planks (our primary system)
- Modular panel sections scale to opening width and height requirements.
- Compression-gasket sealing across threshold and side channels.
- Lower visual impact when stored and cleaner integration on residential facades.
- Easier staged deployment as watch timelines tighten.
- Ideal for most garage, slider, and door opening profiles in Tampa Bay neighborhoods.
Flood Gates
- Hinged gate assemblies can suit specific access-use cases.
- Can require more permanent visible hardware and swing clearance.
- May introduce maintenance points at hinges and gate interfaces.
- Best used where property layout supports gate travel and hardware footprint.
- Not always the best residential fit compared with custom plank systems.
During your assessment, we evaluate whether a flood plank system, gate strategy, or combination is best for each opening. The goal is engineering fit, repeat deployment speed, and long-term seal reliability.

What our customers are saying
EXCELLENTTrustindex verifies that the original source of the review is Google. Lee at Dam it Defense was great. Truly, a quality product and an amazing team.. They are quite busy, but once installed it was worth the wait. Their product is in a class of its own and in high demand.Posted onTrustindex verifies that the original source of the review is Google. Excellent experience all around starting with Mr. Bass, who came to the house for initial inspection and estimate, to the concrete crew whose team- leader ensured excellent cosmetic details and then finally the install crew led by Mr. Michael. The delivered product is great quality, the after installation customer follow up ensured that I was happy and that any trivial details not to my satisfaction were adressed promptly. After dealing with the horrible experience of the failure of traditional sandbags and catastrophic flooding, I feel much better prepared for upcoming hurricane seasons. Highly recommend this company over the competitors- they are local, their product is superior and their pricing better.Posted onTrustindex verifies that the original source of the review is Google. I have Peace of Mind!! After my home was destroyed by Hurricane Helene with the floodwaters and being displaced for 9 months and having to rebuild my home. I started researching the flood barriers to prevent this again. Had 4 companies come out and Lee Bass from Dam it Defense felt to me the most knowledgeable and trustworthy. He put me at ease and did not pressure me, he answered all of my concerns and went as far as to arrange a meeting (my request) for me to see the product installed on a home and I could ask more questions! Lee is top notch! The entire team that I worked with are all great! They earned my trust! No more hurricane flood waters in my house! Thanks to Dam It DefensePosted onTrustindex verifies that the original source of the review is Google. My home was flooded during the September 2024 hurricane events in Florida. We had to completely remove and renovate the lower level of our home, which has been a nightmare. I was approached by Lee Bass, a Dam It Defense representative, who told me about their product. I decided to move forward and purchase their flood defense product as insurance against future flood damage. They kept me informed about the progress of my project while I was awaiting final installation. Once my home was ready for final installation, the process only took a couple days. Their concrete team removed the pavers around my sliding doors to install footers to create a tight seal. The installation team was quick and efficient. I how have the barrier brackets permanently fixed to all of my doorways around my home, and they almost blend in with the normal decor of the home. I plan on painting them the same color to have them blend even further. I hope to never have to use their product, but now I have peace of mind to protect against flooding in the future, and I am so pleased that I never have to wait in sandbag lines again.Posted onTrustindex verifies that the original source of the review is Google. Lee Bass the salesman did a great job for us I would recommend him to everyonePosted onTrustindex verifies that the original source of the review is Google. Here's the deal breaker with Dam It Defense versus everyone else... the service! Lee and his team not only installed the unit in a few hours but they gave me a tutorial afterwards with options on set up and storage. More importantly the product is visually and virtually superior. While im not looking forward to hurricane season, I know that with this dam product, my line of defense is impenetrable!Posted onTrustindex verifies that the original source of the review is Google. The company was easy to work with and did what they said they would do.Posted onTrustindex verifies that the original source of the review is Google. Lee, Matt and John did a fantastic job! They worked with me and explained every step of the process and how these flood gates work to protect the home. Great communication and attention to detail all around. Best part is they will store the flood gates and come out and set them up when a storm is coming so the panels wont take up space in the garage. Amazing workPosted onTrustindex verifies that the original source of the review is Google. Installation was easy. System is better then I expected. Mike answered many and all questions. Andrea the install team were great . I feel very good with my purchase and I am not looking forward to another hurricane but at least I feel confident and proactive if one comes. Thank you Dam it Defense team.Posted onTrustindex verifies that the original source of the review is Google. After being taken out by Helene and a very lengthy rebuild, we found Dam It Defense to be the prevention method that worked best for our coastal home on LBK. Clay was great through the whole process, quotes, demonstration and explanations. The fact that the developers and owners were motivated by their own experiences with Helene and the flood damage, as well as the products resistance to salt water, gave us an extra layer of confidence. The installation crew was great and Michael followed up a number of times, even on his day off. Being part time residents, the storage and installation option for pending storms saves flights back and forth to storm prep. While we hope to never experience this again and is the one product I hope I never have to use, Im thankful that it serves as an extra layer of protection and provides some peace of mind.
Common flood barrier questions.
How much do custom flood barriers cost?
Cost depends on opening count, span width, required barrier height, substrate conditions, and anchoring requirements. Your assessment includes a scoped quote for your exact property.
Are your systems better than sandbags?
For repeat seasonal deployment, yes. Engineered aluminum planks and compression gaskets are more consistent, faster to deploy, and less labor-intensive than stacking sandbags.
Do flood barriers help with insurance conversations?
Documented mitigation can support insurer discussions, depending on your carrier and policy. We provide installation documentation for your records.
Can one home use both flood planks and flood gates?
Yes. Some properties benefit from mixed solutions based on opening geometry, access needs, and deployment priorities.
How long from assessment to install?
Timeline depends on opening volume and fabrication queue. We provide realistic timing during the initial site visit.
Where are systems fabricated?
All systems are fabricated in our St. Petersburg facility and installed by our in-house team.
