Florida’s summer heat isn’t just brutal on you—it’s brutal on your dock.
With UV indexes frequently above 10, salt-heavy air, daily humidity, and hurricane-level storms, South Florida is one of the most aggressive environments for waterfront structures.
For dock owners, especially those with older wood or exposed equipment, routine dock maintenance is critical to avoid rot, corrosion, and structural failure. The average cost to replace a dock in Florida ranges from $15,000 to $35,000. Routine care can help you avoid it.
At Tides Marine Construction, we’ve spent over a decade building and maintaining docks that can withstand Florida’s unique climate. This guide breaks down the 7 most important summer dock maintenance tips for homeowners who want to protect their investment and extend the life of their waterfront.
1. Clean Monthly with Marine-Safe Products
Why it matters:
Dock surfaces accumulate dirt, algae, bird droppings, and salt buildup—especially in the summer heat. If left untreated, these elements hold moisture and create the perfect conditions for rot and slippage.
What to do:
- Use a pressure washer at no more than 1500 PSI to avoid damaging wood or composite materials.
- Apply biodegradable dock cleaners like Wet & Forget or Simple Green Marine to remove stains and biofilm.
- Rinse thoroughly and allow to dry completely before resealing.
Cleaning not only keeps your dock looking good—it prevents structural deterioration.
Note: Avoid chlorine bleach. It’s corrosive to hardware and harmful to marine ecosystems.
2. Inspect for Structural Damage Every Month
What to check:
- Loose or splintering planks
- Protruding nails or screws
- Rusted or bent hardware
- Shifting or leaning pilings
- Gaps in decking or frame
- Wear on ladders, cleats, bumpers, and shelters
Heat expansion, especially with wood, causes screws and nails to loosen. Catching these early can prevent injury and expensive damage.
Post-storm inspections are especially important. Even moderate tropical activity can loosen connections or displace deck components.

3. Re-Stain and Seal Wood Every 2–3 Years
Florida’s UV rays age untreated wood 2–3 times faster than in northern climates. A board exposed to full sun can dry out, split, and gray in a single summer.
Your action plan:
- Re-seal with a marine-grade UV and mildew-resistant product.
- Use a semi-transparent stain to protect the wood while preserving its appearance.
- Spot-replace planks that show early signs of rot or splitting.
This is a critical part of long-term dock maintenance. A $60 gallon of sealant can prevent a $600 plank replacement.
4. Prioritize Dock Equipment Service Maintenance
Your dock is more than wood and nails—it’s a system.
Ladders, gangways, electrical lighting, and boat lifts take on as much heat and salt exposure as the deck itself.
Key areas to inspect and maintain:
- Electrical wiring and junction boxes for corrosion or shorts
- Lighting fixtures for rust, bulb burnout, or water damage
- Boat lift components (cables, pulleys, motors) for signs of wear
- Docking shelters and canvas awnings for tears, mold, or UV damage
We recommend annual maintenance programs for dock equipment and lifts to ensure safety and reduce downtime during boating season.
5. Rinse Hardware and Metal Fittings Weekly
Salt corrosion is the number one cause of fastener and bracket failure on docks.
Over time, rust weakens structural integrity—especially on aluminum or steel parts exposed to splash zones.
How to stay ahead of it:
- Use a garden hose with fresh water weekly to rinse exposed metal
- Apply anti-corrosion sprays or marine grease to moving parts
- Replace rusted bolts, washers, or angle brackets immediately
Routine rinsing can extend the life of your dock’s hardware by several years.
6. Monitor Your Pilings and Foundation
Your dock is only as strong as what it’s built on.
Pilings are constantly exposed to tidal changes, saltwater, marine pests, and shifting soil. A weak piling can cause sagging, instability, and even dock collapse.
Warning signs:
- Vertical cracking or visible rot on wooden pilings
- Movement or wobble in the deck above
- Discoloration or sponge-like texture near the waterline
- Sand loss around the base
If you notice these issues, contact us immediately for piling repair. Delayed action can compromise the entire dock.
7. Evaluate the Seawall for Signs of Stress
If your dock is connected to or near a seawall, your maintenance checklist needs to include it.
A compromised seawall undermines everything.
According to FEMA, poorly maintained seawalls are one of the leading causes of flood-related property damage on the Florida coast.
What to look for:
- Cracks or crumbling along the cap
- Bulging or bowing of wall sections
- Sinkholes or soil loss behind the wall
- Visible water seepage during high tides
Our team at Tides Marine Construction provides full seawall inspections and replacements to ensure long-term shoreline protection.
