We flooded too.
So we built something better.
Dam It Defense started after Hurricane Helene flooded our founders’ own homes in St. Petersburg. We couldn’t find a flood barrier we trusted, so we built one, drawing on over a decade of experience in aluminum manufacturing.
Today every system is measured, fabricated and installed by our own team in St. Pete, for homes, businesses, HOA communities and municipalities.

Providing Local Support and Relief When Disaster Strikes
Dam It Defense has partnered with the Cajun Navy Relief to provide funding and support to the local community when it needs it most. After deploying our flood prevention systems ahead of a hurricane, we will be reallocating our resources, including our fleet of Humvees capable of navigating 30 inches of water, to assist in search and rescue as well as other forms of aid.
We chose to partner with the Cajun Navy Relief because they are a group of volunteers who work tirelessly without pay to provide immediate rescue and relief during natural disasters across the United States. This is one of our many efforts to remain ST PETE STRONG.

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 on 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 on 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 on 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 on 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 on 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 won’t take up space in the garage. Amazing workPosted on 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 on 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, I’m thankful that it serves as an extra layer of protection and provides some peace of mind.
Frequently Asked Questions
Straight answers about flood barriers, installation and cost.
Get my exact quote freeHow much do flood barriers cost?
Dam It Defense systems start at $499 per opening. Your total depends on how many openings you protect and their size. The free on-site assessment gives you an exact, itemized quote, and flexible financing is available. See flood barrier cost.
What is a free flood assessment?
We come to your property, walk every opening water can enter, measure each one and give you an exact, itemized quote. No cost and no obligation.
How are flood barriers different from flood gates or flood planks?
Our panels are custom-measured aluminum barriers that lock into channels mounted to your home and seal with compression gaskets, rather than one-size gates or loose planks. Here is how to choose a flood barrier.
How fast can the barriers go up before a storm?
The channels stay mounted to your home and every panel is labeled for its opening, so most systems go up in about an hour with no special tools.
How much water can they hold back?
Our systems are rated to hold back up to 10 feet of water under sustained load, and each one is sized to your specific openings.
Where are the barriers made?
Every system is fabricated at our own facility in St. Petersburg and installed by our own licensed crew. No subcontractors and no outsourced fabrication.
Where do the panels go when they are not deployed?
We offer storage solutions with labeled panel organization and dedicated hardware containment, so your system is ready to deploy the moment a storm is named.
Can flood barriers lower my flood insurance?
Dam It Defense customers can save 5% on flood insurance through our insurance partner. Check with your own provider for other discounts.
Do you offer financing?
Yes. Monthly payment options are available through Hearth, with a 60-second pre-qualification that does not affect your credit score.
What areas do you serve?
St. Petersburg, Tampa Bay and Pinellas County, plus the Gulf Coast and Southwest Florida, including Anna Maria Island, Sarasota, Port Charlotte, Fort Myers, Cape Coral and Naples.
