Gibson Marine Construction is a licensed marine contractor with deep experience building and repairing seawalls throughout Florida’s Gulf Coast.

Our crews are trained in both concrete and vinyl piling seawall systems, so we recommend the right solution for your situation instead of a one-size-fits-all approach.
We also handle the full scope of waterfront construction, from docks and boat lifts to bulkheads and accessories. That means if your seawall repair reveals related damage to your dock or shoreline structure, you are working with one contractor who can address everything. You can learn more about our approach and history on our About Us page.
We do not subcontract our marine work. Our own crews show up, do the job right, and stand behind it. That is the difference between a contractor who builds a relationship with you and one who disappears after the invoice is paid.
DIY Seawall Patching vs Professional Seawall Repair: What St. Armands Homeowners Should Know
Hardware store patching compounds and epoxy kits might slow down a small surface crack, but they do nothing for the structural problems behind it. Most seawall failures in St. Armands start below the waterline or at the tieback connections, areas that require marine-grade equipment and engineering knowledge to properly fix. A surface patch on a structurally compromised wall gives you a false sense of security heading into hurricane season.
Professional seawall repair addresses the root cause. That means checking the footing, replacing failed tiebacks, stabilizing backfill, and reinforcing or replacing panels that have lost their load-bearing capacity. Gibson Marine Construction has been doing this work across the Gulf Coast for years and understands the specific soil conditions and tidal forces that St. Armands seawalls face.
If your wall has a single hairline crack and zero soil loss, a DIY sealant might buy you some time. But if you see any leaning, settlement, or washout, a professional repair is the only option that actually protects your property.

Your Seawall Repair Questions Answered — St. Armands, FL
How do I know if my seawall in St. Armands needs repair or full replacement?
A qualified marine contractor can tell you after an on-site inspection that includes checking the wall below the waterline. Minor cracking and surface spalling can often be repaired. But if the wall is leaning more than a few inches, has multiple failed tiebacks, or shows major panel displacement, replacement is usually the better long-term investment. St. Armands seawalls deal with constant salt exposure and tidal pressure, so catching problems early almost always saves money.
Do I need a permit for seawall repair in St. Armands, FL?
Yes, most seawall repairs in St. Armands require permits through Sarasota County, and some projects also need approval from state environmental agencies. Gibson Marine Construction handles the full permit process for you so nothing gets missed or delayed.
How long does a seawall repair take in St. Armands?
Most seawall repairs take between one and three weeks of active construction, depending on the scope of the damage. Permit approval timelines in Sarasota County can add several weeks before work begins. We give you a clear timeline after your initial site evaluation.
What causes seawalls to fail on St. Armands Key?
The combination of saltwater corrosion, tidal pressure, storm surge, and soil washout behind the wall is what breaks down most seawalls on St. Armands. Concrete walls are especially vulnerable to rebar corrosion from salt intrusion. Hurricane seasons accelerate the damage significantly, which is why regular inspections matter.
Is a vinyl seawall better than concrete for St. Armands properties in 2026?
Vinyl sheet pile seawalls resist salt corrosion far better than traditional concrete and typically last longer in Gulf Coast conditions. They are a strong option for many St. Armands properties, especially where the existing concrete wall has corroded beyond practical repair. Gibson Marine Construction installs both materials and can walk you through the best fit for your specific shoreline.
