Hurricane Ian Rebuilds
Hurricane Ian damaged thousands of Cape Coral canal seawalls when it made landfall on September 28, 2022. Years later we are still pulling Ian-related repair and replacement permits across the City. If you have an open insurance claim, a denied claim, or a wall that has been waiting on a contractor, we will inspect, document scope-of-loss, prepare engineered drawings to current Cape Coral Land Development Regulation standards, and work directly with your adjuster.

What Goes Wrong
Cape Coral seawalls fail in predictable ways. The city was carved from marshland starting in 1957, so most lots are reclaimed dredge fill on a sandy substrate, which behaves very differently from natural ground. Add brackish canal water, hurricane surge, and 50-plus year old original concrete, and the failure modes below are what we see most often during free inspections.
Hairline cracks let saltwater reach the rebar. Once steel corrodes, it expands up to 7 times its original volume per the American Concrete Institute, splitting the cap from the inside.
Internal data: 74 percent of Cape Coral seawall caps we inspect from the 1960s and 1970s show measurable rebar corrosion. Cap repairWhen the cap pulls away from the panel below, the dredged fill behind the wall escapes into the canal and the wall loses lateral support. A half-inch gap can let cubic yards of soil drain over a single tide cycle.
Industry figure: 1 inch of cap-panel separation can release 8 to 12 cubic feet of soil per linear foot per year (FDEP studies). Cap restorationVoids behind a seawall stay invisible until a section of yard, driveway, or pool deck drops. Cape Coral's sandy dredge-fill soil flushes out fast once a leak path opens, and Ian accelerated this on thousands of walls.
EPA reports Gulf of Mexico sea level has risen approximately 6 to 8 inches since 1950, accelerating hydraulic flushing of fill. Void repairSalt spray and chloride ingress drive rebar corrosion in coastal concrete. NACE estimates corrosion costs U.S. infrastructure 276 billion dollars per year, and waterfront concrete is among the worst-affected categories.
ACI guideline: 1.5 inches of clear cover is required for concrete in saltwater. Older Cape Coral caps often have under 1 inch. Spalling repairTiebacks are the buried anchors that keep a seawall from rotating toward the canal. When they corrode or pull through the soft fill, the wall begins to lean. A 1-inch lean at the top usually means several inches of rotation below the waterline.
Internal data: 38 percent of pre-2000 Cape Coral seawalls show measurable rotation by year 25. Tieback repairHurricane Ian made landfall on September 28, 2022 with sustained Cat 4 winds in Lee County. NOAA recorded storm surge of 10 to 15 feet across parts of Cape Coral, overtopping nearly every canal seawall in the city. Charley in 2004 and Irma in 2017 added their own damage.
NOAA storm-surge atlas: Ian produced 10 to 15 ft surge along Lee County canals, the highest on record. Storm repairWhat We Do

Learn moreWhy Cape Coral Chooses Us
Cape Coral was dredged from marshland starting in 1957. Most lots are reclaimed fill on sandy substrate, with brackish water tides moving up and down the canal network twice a day. We engineer every repair to those exact conditions: galvanized hardware rated for ASTM B695 saltwater service, mix designs with corrosion inhibitors, and tieback depths sized to local soil borings rather than generic Florida averages.
Designed to ASTM B695 class 55 saltwater specWe mobilize from the canal using a shallow-draft work barge whenever conditions allow. That means no track-hoe on your lawn, no torn-up pool cage, and no surprise landscape restoration charges. For polyurethane foam injection in particular, the only access we need landside is a series of dime-sized injection ports through the cap.
85 percent of our jobs need zero landscape restorationEvery contract includes fully managed permitting through the City of Cape Coral, Lee County DCD, FDEP, and the U.S. Army Corps of Engineers when applicable. For Hurricane Ian rebuilds we prepare scope-of-loss documentation, work with adjusters and public adjusters, and design to current Cape Coral Land Development Regulation elevation and structural standards.
Permit prep, submission, and issuance handled end-to-endHow It Works
Above-water and underwater inspection of the cap, panels, tiebacks, and bottom scour. Written findings within 48 hours.
Scoped, line-item written estimate with method options, materials, warranty terms, and timeline. No high-pressure close.
We prepare sealed drawings, submit to the City of Cape Coral, Lee County, FDEP, and USACE when required. You sign once. We track and confirm issuance.
Crew arrives on the scheduled day with all materials. Final inspection, walkthrough, and signed 30-year transferable warranty paperwork before we leave.
Free Estimate
With more than 400 miles of canals in Cape Coral and thousands of Ian-damaged walls still in the repair queue, scheduling is tighter every year. The earlier you start, the more time you have for engineering, permits, and scheduling around hurricane season. Free inspection, no obligation.
Insurance Claim Assistance
Most Cape Coral seawall insurance claims rise or fall on engineering documentation, not on the visible damage. We prepare measured drawings, scope-of-loss letters, structural assessments, and cost backup that adjusters can act on. We coordinate with your public adjuster or attorney if you have one. The inspection is free and the documentation work is rolled into the project scope when you hire us to do the repair.
What Cape Coral Says
"Surge from Ian had washed out a 30 foot section of yard behind our cap. They injected polyurethane through ports in the cap, brought the grade back up, and the lawn is solid again. Documented the loss for our adjuster too. Two years in, no settlement."Helen K.SE Cape Coral · Polyurethane void fill
"Decades of saltwater had exposed the rebar through most of the cap. They removed the failed concrete, replaced corroded bar with epoxy-coated stainless, and patched with marine-grade mortar with inhibitor. Best documented repair I have seen on any home improvement project."Anthony D.Cape Harbour · Concrete spalling repair
"Two tiebacks had clearly failed and the cap was rotating toward the canal. They installed new helical anchors through the cap with all the torque logging the engineer wanted. Clean job, no excavation, no landscape repair after."Olivia F.Tarpon Point · Helical anchor pull-back

ViewAbout Us
Cape Coral Seawall Repair is a licensed Florida marine contractor focused exclusively on seawalls, bulkheads, and the structures that protect waterfront property across Cape Coral and Lee County. We have spent more than a decade repairing, replacing, and elevating walls from the Yacht Club to Tarpon Point and up the canals to NE Cape Coral. We do not chase pool decks, driveways, or general home services. Seawalls are the only thing we do, and that focus is why we can offer a 30-year transferable warranty in writing.
FAQ
Common signs of a failing Cape Coral seawall include cap cracks wider than a quarter inch, soil washing or sinkholes forming behind the wall, gaps opening between the cap and panels, rebar staining or rust streaks on the concrete face, sections of the wall leaning toward the canal, and water visibly pushing through joints at high tide. Any one of these warrants a free underwater inspection. What looks like a small problem above water often hides significant scour, void, or tieback failure below the waterline, particularly on walls that absorbed Hurricane Ian storm surge.
Yes. Lee County DCD and the City of Cape Coral are still processing Ian-related seawall permits years after the storm. The 2022 hurricane damaged thousands of Cape Coral canal seawalls, and many homeowners filed insurance claims that are still being resolved. We work directly with adjusters, public adjusters, and engineers to document scope, scope-of-loss, and code-compliant rebuild plans. Cape Coral seawalls rebuilt today must meet current Land Development Regulation cap elevation and structural standards, which differ from the original 1960s and 1970s construction.
Cape Coral seawalls fall under the Land Development Regulations and the Florida Building Code. New and replacement seawall caps in Cape Coral are typically required at a minimum elevation referenced to NAVD 88 datum, with additional requirements for tieback design, panel embedment, and reinforcement. After Hurricane Ian, the City has been more rigorous on enforcement of cap elevation and freeboard above mean high water. We design every project to meet or exceed current code and FEMA flood-zone considerations for your specific parcel.
Repair is the right call when the cap is intact, panels are sound, and the issue is soil loss, minor cracking, tieback failure, or localized spalling. Repair typically costs 50 to 75 percent less than full replacement and can be completed in 1 to 5 days using polyurethane foam injection, helical pile anchoring, and cap restoration. Replacement is warranted when panels are perforated, the wall has rotated significantly, or the structure has exceeded its useful life. Many Cape Coral seawalls from the 1960s and 1970s original development are now past that point. We provide a free underwater inspection and a written recommendation, not a sales pitch.
Yes. Every project includes fully managed permitting through the City of Cape Coral, Lee County DCD, FDEP for state submerged lands, and the U.S. Army Corps of Engineers for navigable waters when applicable. We prepare sealed engineering drawings, environmental documentation, and submit on your behalf. You sign once at the start, and we manage the rest until the permit is issued and the final inspection passes.
Most polyurethane foam injection projects are completed in a single day. Helical pile anchoring and tieback repairs typically run 2 to 5 working days. Cap restoration is usually 3 to 7 days. Full panel replacement or new seawall construction generally runs 3 to 8 weeks including cure time. Emergency stabilization for active failure or post-storm damage can begin within 24 to 48 hours of inspection, with permanent repair scheduled around permitting.
We work waterside from a barge whenever the canal allows it, which means no excavator on the lawn, no torn-up pool deck, and no landscape restoration costs added to the job. Polyurethane foam injection in particular is done through small dime-sized injection ports through the cap, leaving the surface essentially untouched. For repairs that require landside access, we protect surfaces with plywood, plate steel, and ground mats, and we include surface restoration in the written estimate before work begins.
Yes. We offer a 30-year transferable warranty on engineered seawall repairs and new construction, with line-item terms in writing on every contract. Polyurethane foam void fills, helical pile anchoring, cap restoration, and new panel installation each carry specific structural and workmanship coverages within that warranty framework. The warranty transfers to subsequent owners at no cost, which is a documented value-add when you sell.
Polyurethane foam injection void repair generally runs 35 to 95 dollars per linear foot depending on void volume. Cap crack and spall repair runs 60 to 180 dollars per linear foot. Helical pile tieback installation runs 1,800 to 3,500 dollars per anchor, with most residential walls needing one anchor every 6 to 10 feet. Full seawall replacement in Southwest Florida averages 850 to 2,200 dollars per linear foot depending on panel type, cap design, and access. Free written estimates are always provided after inspection.
