Why it matters here
Water does not have to reach the roof. It only has to reach the garage.
Southwest Florida floods from the bottom up: storm surge, canal rise and heavy rain find the lowest opening first. These are the figures Rubicon plans against.

Engineering
6063-T6 aluminum. Tested, not claimed.
Sandbags leak at every joint. Plywood floats. A Rubicon barrier is interlocking aluminum planks with closed-cell EPDM seals, pressed down into posts that are anchored once beside the opening, and it seals tighter as water pushes against it.
Full specifications- 31.0 KSI: Tested plank yield
- An independent tensile test of a production plank measured 31.0 ksi yield and 35.5 ksi ultimate, against ASTM B221 T6 minimums of 25.0 and 30.0. Material verification, not a system certification.
- 25–73 IN: Protection height
- Three to nine planks, 8 inches each. The height for each opening is set during measurement from the ground elevation, past water lines and the flood zone.
- 2.15 LB: Per foot of plank
- A 10-ft plank weighs about 21.5 lb. One person carries it, stacks it and takes it down. Side posts stay; everything else stores flat.
Our process
From the first call to a closed opening. Seven steps, measured first.
Review the water path
List the openings water has reached, where it came from first, and who will deploy the system.
Measure each opening
Clear width, protection height, threshold profile, jambs, obstructions, corners and how panels reach the opening.
Check the substrate
CBS, stucco, wood and tile each mount differently. Rubicon finds the load-bearing surface behind the finish.
Design and quote
Plank lengths, stack height, post locations and labels are set, and a written quote follows.
Fabricate and install
Channels and hardware are installed at the designed line, and fasteners are sealed.
Test deploy and hand off
Rubicon assembles the full system with you, checks seal contact, labels everything and agrees a storage spot.
Inspect each season
Before hurricane season, check labels, seals, channels and hardware, and book service for worn parts.
Between storms
Stored on site. Deployed by you.
Homeowners deploy the system themselves after Rubicon installs the posts and walks through the sequence. Bring the labeled planks to the right opening, clear and check the floor seal line, set any center post specified for the span, stack the planks in order, engage the compression hardware and check that the seal touches all the way along.
- Follow the opening label and the installed sequence
- Keep grit and debris out of the seal contact areas
- Do not leave out a required plank or support
- Rinse, dry and store the planks after the event
What we measure
One system. Every opening on the house.
Each opening has its own width, threshold and mounting surface. Start with the one water has used before.
Opening types
Garage flood barriersGarage openings are often the first place water gets in: the driveway slopes toward the door, the threshold is low and the span is wide.Fit and limits- Entry door flood barriersEntry doors are narrow but low.Fit and limits
Sliding glass door flood barriersSliders are wide, sit low and have tracks and weep holes that water can follow.Fit and limits
Lanai and wide-opening flood barriersLanai runs are long, often turn corners and meet screen frames.Fit and limits
Bookable visits

- Pre-season barrier inspectionFor owners of an installed Rubicon system: a technician checks panels, labels, EPDM seals, side channels, center posts and compression hardware, performs a test deployment with you and flags worn parts before hurricane season.Choose a day and time
Cost
What a measured barrier costs. Ranges now. Exact quote after measurement.
A measured, installed aluminum flood barrier runs about $2,200 to $4,800 for a front door and $2,800 to $6,500 for a single-car garage. Width, required height, number of openings and the mounting surface set the written quote.
Rubicon publishes planning ranges so you can budget, not per-foot prices that cannot be compared to a measured, installed opening.

Straight answers
Will a barrier lower my flood insurance?
Not automatically. NFIP premiums are driven mainly by elevation and building characteristics; some private carriers consider documented mitigation. Ask your carrier before you buy, and keep Rubicon's measurement and installation paperwork.
What a barrier cannot do
A barrier closes one measured opening up to its rated height. It does not stop water through floor drains, walls or over the top. Where water gets past a barrier

FAQ
Common questions.
Short answers about the system, the visit and the people who install it. Topic questions live on their own pages.
Book a free assessmentWhat does Rubicon Flood Control install?
BarrierX® removable aluminum flood barriers, sold as Rubicon Flood Panels: interlocking 6063-T6 aluminum planks with closed-cell EPDM seals that stack between side posts anchored beside a garage, door, slider or lanai opening. Rubicon measures the opening, fabricates the planks to that measurement, installs the posts and hardware, and walks you through deploying it.
What is BarrierX?
BarrierX® is the removable aluminum plank flood barrier system Rubicon installs. Planks are 6063-T6 aluminum, 8 inches tall each, stacked from 3 planks (25 in) to 9 planks (73 in). An independent tensile test of a production plank measured 31.0 ksi yield against the 25.0 ksi ASTM B221 T6 minimum.
Is the on-site assessment free?
Yes. The on-site flood barrier assessment is a free estimate visit, about 60 minutes at your property. A specialist traces how water reaches the home, measures each opening and sends a written quote after the visit.
How tall a flood barrier can Rubicon install?
From 25 inches (3 planks) to 73 inches (9 planks), in 8-inch steps. The height for each opening is set during measurement from the ground elevation at the opening, where water has reached before and the flood zone, not from a catalog.
What should I have ready for the assessment visit?
Know which openings water has reached before. Photos of past water lines help. Clear access to garage and lanai openings. Someone should be home to open the garage and lanai and to talk through where water came in before.
How quickly does Rubicon respond?
Rubicon replies within an hour during business hours and can schedule an emergency appointment within 24 hours. Visits are booked online at rubiconflood.com/book/flood-barrier-assessment or by calling (239) 330-8888.
