Central Florida Seawall Inspection Checklist: 7 Signs Your Seawall Won't Survive the 2026 Hurricane Season

Hurricane season officially starts June 1. That gives you about seven weeks.

Seven weeks to walk your waterfront, look your seawall in the eye, and decide whether it's ready for what Central Florida summers can throw at it. Seven weeks to get a contractor out, pull a permit, and get real work done before storm surge, wind-driven waves, and saturated soils start doing the inspecting for you.

We built our company on seawalls, docks, and boathouses, and every year we see the same thing: homeowners who waited one season too long. A seawall that could have been repaired for a few thousand dollars in April becomes a full replacement in October. The damage almost never announces itself — until it does, all at once.

So before the first named storm forms in the Atlantic, grab this checklist, put on a pair of boots, and walk your waterline. Here are the seven warning signs we look for on every inspection, and what each one actually means.

1. Cracks Wider Than a Quarter Inch

Hairline cracks in a concrete or cap-poured seawall are normal. Concrete cures, shrinks, and settles — a few fine lines are part of the deal.

What you're looking for is different. Cracks wider than about a quarter inch — roughly the width of a pencil — tell you the panel or cap is moving. Horizontal cracks are the ones that really get our attention, because they usually signal pressure building up behind the wall from saturated soil. When a hurricane dumps six inches of rain in twelve hours, that pressure doesn't just build. It blows out.

Mark any cracks you find with a grease pencil and note the date. If they grow between now and June, that's a wall in active failure and it needs professional eyes on it immediately.

2. Soil Washout or Sinkholes Behind the Cap

Walk the yard side of your seawall and look for low spots, dips, or soft ground along the cap. You can also probe with a long screwdriver — if it slides in six or eight inches without resistance, you've got a void under your feet.

Voids behind the cap almost always mean water is moving through your wall when it shouldn't be. Either the weep holes are clogged (more on that in a minute), the tie-back rods have failed, or the panels themselves have separated at the joints. Every time the tide or the lake level rises and falls, a little more of your yard gets pulled out through the gap.

A minor washout is a repair. A major one, or several of them in a row, is often a sign the wall is ready to come down on its own schedule.

3. The Cap Is Leaning Toward the Water

Stand at one end of the seawall and sight down the cap like you're looking down a rifle barrel. It should be straight, level, and plumb.

If the cap is bowing outward, tilting waterward, or has a visible hump or dip in the middle, the tie-back system behind the wall is compromised. Tie-backs are the steel rods that anchor the wall into the deadman buried in your yard. They corrode. They snap. And when they do, the only thing holding the wall up is the weight of the wall itself — which is not nearly enough when a storm surge hits.

This is one of the clearest signs that a full repair, and sometimes a replacement, is on the horizon. It's also one of the most fixable if you catch it early.

4. Blocked or Missing Weep Holes

Weep holes are the small drains at the base of your seawall that let groundwater escape back into the lake or waterway. They are not decorative. They are the pressure-release valve for the entire structure.

Walk the waterline at low tide and look for them. You should see water trickling out during or after a rain. If they're packed with mud, roots, mussels, or sand — or if you can't find them at all because someone buried them under riprap or fill — your wall is holding back every drop of water on your property.

Clearing weep holes is usually cheap. Replacing a wall that failed because the weep holes were blocked is not.

5. Exposed or Rusted Rebar

Spalling is the industry word for what happens when water gets into concrete, finds the rebar, rusts it, and pops chunks of concrete off the surface as the steel expands. Once you see orange streaks or exposed rust-colored bar, the clock is ticking.

In saltwater environments along the Gulf, this happens fast. In our freshwater lakes — Lake Weir, the Harris Chain, the Ocklawaha — it happens slower, but it still happens, especially on older walls that predate modern epoxy-coated rebar.

If you can see rebar at all, the wall has already lost its structural skin. Storm waves will accelerate the decay dramatically.

6. Separated Panels or Visible Gaps at the Joints

Run your hand (carefully) along the seams between seawall panels. You're feeling for gaps, shifts, or places where one panel has rotated forward of its neighbor.

Small gaps can sometimes be sealed. Larger ones — anything you can fit a finger into — usually mean the panels are no longer working as a unified wall. They're working as individual pieces, which is a problem, because a seawall's strength comes from the whole structure acting together.

Panels that have rotated or stepped out of alignment are telling you the soil behind them is on the move.

7. Damage to the Dock, Boathouse, or Deck That Ties Into the Wall

Your dock and your seawall are married. They share loads, they share fasteners, and in a lot of cases they share structural members. If your dock or boathouse is showing signs of stress — sagging boards, pulled fasteners, cracked pilings, a finger pier that's separating from the main run — the seawall behind it is almost certainly part of the story.

Don't treat them as separate projects. A good marine contractor will look at them as a single system, because that's how a hurricane will treat them.

DIY Inspection vs. Calling a Pro

You can handle the walk-through above in about an hour with a screwdriver, a tape measure, and a phone camera. That's real, useful work, and we'd rather have a homeowner who's been paying attention than one who hasn't.

But there are three situations where you should stop inspecting and pick up the phone:

You found two or more warning signs from the list above. Problems on a seawall don't show up in isolation. When you see multiple symptoms, the wall is telling you the underlying system is compromised, and a professional assessment becomes a matter of when, not if.

The wall is more than twenty years old. Older seawalls were built to different standards, with different materials, and against different water levels than what Central Florida sees today. A professional inspection every three to five years is cheap insurance.

You're planning to ride out the storm at home. If your family's safety depends on that wall holding, you want a second set of trained eyes on it before June 1.

What Happens If You Wait

We're not going to sugarcoat this part. A seawall that fails in a storm doesn't just cost you the wall. It costs you the yard behind it, the landscaping, sometimes the pool deck or the dock, and occasionally a section of the house itself. Insurance coverage for seawalls is notoriously uneven — many policies exclude them entirely, and the ones that cover them often require documented pre-loss inspections.

A repair in April is a line item. A failure in September is a project.

Pre-season repairs also move faster. Permit offices get swamped after major storms, contractors book out months in advance, and material prices spike. Getting on a schedule now means the work actually gets done before the water starts rising.

How JSC Contracting Approaches Seawall Work

We started in marine construction. Our roots go back to the 1984 founding of Labagh Marine, which we acquired in 2020, and seawalls have been part of our daily work ever since. We handle new construction, repairs, tie-back replacement, panel work, weep hole rehabilitation, and full replacements across Central Florida's lakes, rivers, and coastal communities.

We also handle the permitting. Every city, county, and state agency has its own process, and it's one of the main reasons waterfront projects stall out. We've pulled enough permits in Marion, Lake, Sumter, and surrounding counties that we know what each office wants before we walk in the door.

If you want the full picture of what we build, the Services page walks through our marine, residential, commercial, and agricultural work. And if a seawall isn't the only thing on your list this spring, we also build barndominiums, pole barns, and custom homes — so a single call can cover the whole property.

Book a Pre-Season Inspection

We're booking free pre-season seawall inspections through the end of May. One of our marine team members will walk your property, check every item on the list above, take photos, and give you an honest read on what the wall needs — whether that's a small repair, a full replacement, or nothing at all.

No sales pressure. No upsell. Just a straight answer before hurricane season starts writing one for you.

Contact us to get on the schedule, or call (352) 687-2030 to talk to someone today. You can also meet the team that will be showing up at your door.

You dream it, we build it — and when the water rises, we make sure it holds.
