LARGO FLOOD BARRIERS. BUILT FOR THE WATER MILTON BROUGHT.
Custom aluminum panels measured to the openings on your house, fabricated at our own Florida factory and installed by our own crew. Built for the creekside and low-lying homes of Largo and mid-Pinellas.
Most Largo flood barriers are sold as one-size kits shipped in a box. Ours are measured to your exact doors, garage and sliders, from the streets along McKay Creek and Church Creek to the low-lying blocks of mid-Largo.

Largo floods from the creeks and the rain.
In August 2024, Tampa Bay recorded 17.78 inches of rain, a record for the month according to the National Weather Service, and the City of Largo reported flooding in several neighborhoods at levels not seen in many years.
Then came Helene and Milton. During Milton, Largo’s city manager put rainfall at 12 to 15 inches. McKay Creek overflowed into homes along Crescent Drive, where one resident said water reached about 18 inches inside a neighbor’s house, and Church Creek neighbors reported flooding too.
Largo does not need storm surge to flood. Heavy rain, high creeks and backed-up storm drains put water at the lowest openings first: garage doors, entries and sliders. That is what a flood barrier is built to seal.

That much rain in one storm overwhelms creeks and storm drains. When they back up, the water heads for the lowest openings on the house.

Flood damage repeats every time the water comes back. A barrier system is a one-time cost that goes up every storm.
The water comes from the creeks, the drains and the rain.
Largo sits in the middle of Pinellas County, laced with creeks that drain toward the bay. In a big storm, water comes from more than one direction.
Creekside homes
Homes along McKay Creek, Church Creek and Allens Creek flood when the creeks overflow their banks. Water crosses the yard and comes straight at the lowest openings.
Low-lying neighborhoods
The City of Largo calls mid-Largo, between Rosery Road and East Bay Drive, prone to flooding. When storm drains back up, low streets and driveways fill first.
No surge required
During Milton, rain alone pushed water into Largo homes that never expected it. You do not need to live on the water to need a barrier.
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 opening, so anyone in the house can put the whole system up in about an hour. Our crew walks you through it at install.

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.
Nothing changes day to day
Panels go up only when a storm is coming. The rest of the year the channels sit flush and out of the way.
Up in about an hour
Every panel is labeled for its opening. When a storm is named, your system goes up in about an hour.
For seasonal homes too
If you are up north when a storm is named, a property manager or neighbor can deploy it. We show them how at install.
Our crew, not a subcontractor
We fabricate in St. Petersburg and our own team does the measuring and the install in Largo and across Pinellas County. 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

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
