Annual Inspection Checklist for Seawalls, Docks & Boat Lifts

From calm mornings on the dock to family days on the water, coastal living is unmatched; but the same environment that makes it beautiful can also cause hidden wear on your seawall, dock, and boat lift. Saltwater, shifting tides, and storms all take their toll over time.

Scheduling a professional inspection each year helps protect your property, prevent costly repairs, and keep everything running safely. Use this checklist to perform your own review, or schedule an inspection with Duncan Seawall, Sarasota’s trusted marine construction experts.

Why Annual Inspections Are Essential for Waterfront Structures

Florida’s weather and tides create a constant push and pull on marine structures. Saltwater weakens metal, concrete expands under heat, and tidal shifts erode soil and foundations. Without regular checkups, these small issues can quietly develop into major structural failures.

Annual inspections help catch these signs early. Detecting cracks, corrosion, or misalignment before they worsen can save thousands in repairs. Professional inspectors also use sonar mapping, pressure testing, and underwater cameras to reveal damage you can’t see above the surface.

According to the Florida Department of Environmental Protection’s Coastal Construction Guidelines, maintaining your shoreline structures is essential to protect nearby land and waterways. You can also explore NOAA’s insights on coastal erosion and sea level rise to better understand how Florida’s coastal conditions affect your property year-round.

Seawall Inspection Checklist

Your seawall is your property’s first line of defense. During your yearly inspection, start with a check for visible damage, then move through these key areas:

• Cracks or bowing: Walk along the wall and note any horizontal or vertical cracks, leaning panels, or bulging sections that suggest shifting pressure.
• Joints and seams: Check that seams are sealed and there are no gaps where water can seep through and erode soil.
• Erosion or soil loss: Soft spots or sinking areas behind the wall can indicate internal damage.
• Drainage holes: Make sure weep holes are clear to relieve pressure behind the wall.
• Metal components: Look for rust or exposed rebar, which weaken structural strength.
• Cap condition: Cracked or chipped concrete along the top edge can signal stress and should be repaired.

If you notice any of these warning signs, it’s time for a full integrity assessment. Duncan Seawall offers detailed seawall inspections and long-lasting repairs using materials built for Florida’s coastal climate.

Dock Inspection Checklist

A stable dock keeps your waterfront functional and safe for family and guests. Regular maintenance can extend its life and prevent small issues from becoming safety hazards.

Here are some things you should look at:

• Pilings: Check for wood rot, marine borer damage, or cracks in concrete pilings.
• Decking boards: Replace warped or slippery boards to prevent accidents.
• Hardware and fasteners: Tighten or replace any loose or corroded bolts and brackets.
• Railings and ladders: Ensure all attachments are stable and rust-free.
• Electrical systems: Outlets and lighting should be corrosion-free and protected with GFCI circuits.
• Fenders and bumpers: Swap out worn protection to prevent damage to your boat.
• Rinse with fresh water: After exposure to saltwater, give your dock a thorough rinse to remove buildup and prevent long-term damage.

Boat Lift Inspection Checklist

Your boat lift keeps your vessel clean, safe, and ready for the water. A quick annual check can prevent mechanical failures and extend its lifespan.

Here’s what to focus on during your annual boat lift inspection:

• Cables and pulleys: Look for fraying or rust that could cause uneven lifting.
• Lubrication: Apply marine-safe lubricant to keep moving parts running smoothly.
• Limit switches and remotes: Test to ensure the lift stops properly at both top and bottom positions.
• Bunks and brackets: Replace any loose or cracked pieces and check alignment so your boat sits evenly.
• Motors and wiring: Watch for corrosion, frayed wires, or unusual sounds during operation.

Annual servicing by professionals like Duncan Seawall ensures your lift stays balanced, reliable, and safe for daily use.
