Step-by-step floating dock construction plans (DIY + pro)

Florida waterfront living isn’t complete without a dock. For many property owners, a floating dock is the best option — it rises and falls with the tide, requires less maintenance in shallow water, and offers flexibility for boat owners. But how do you actually build one? Here’s a step-by-step guide covering both DIY construction and what to expect when hiring a professional.

🛠️ Step 1: Planning Your Floating Dock

  • Check local permits: In Collier County, Naples, or Marco Island, you must apply for permits before starting.
  • Decide on size and shape: Most floating docks are 8–10 feet wide and can extend 20–40 feet.
  • Select materials: Common choices include wood decking or composite decking (Fiberon) for durability.

⚓ Step 2: Building the Frame

  • Cut treated lumber or aluminum beams for the outer frame.
  • Use galvanized hardware to prevent corrosion.
  • For DIY projects, make sure corners are reinforced with steel brackets.

🧊 Step 3: Adding Floats

  • Install drums, plastic barrels, or foam-filled floats underneath the frame.
  • Space floats evenly to keep the dock balanced.
  • Ensure floats are sealed and UV-resistant for Florida sun exposure.

🌊 Step 4: Decking Installation

  • Lay decking boards across the frame.
  • For longevity, many homeowners in Florida choose Fiberon composite decking — no rot, minimal maintenance.
  • Leave small gaps between boards for drainage.

🔗 Step 5: Anchoring the Dock

  • Use pilings, chains, or cables to secure the dock.
  • Floating docks must remain stable but flexible with tides and boat movement.
  • In hurricane-prone areas, anchoring systems must be extra strong.

👷 Step 6: DIY vs. Professional Construction

  • DIY build: Cost-effective, but requires skills, tools, and strict safety checks.
  • Professional build: Licensed marine contractors (like SeaBee Marine Construction, CGC 1536998) ensure permits, engineering, and hurricane-ready construction.

A floating dock can transform your waterfront property — but it must be built to last in Florida’s climate. If you’re unsure about DIY, let a professional handle design, permits, and construction for long-term peace of mind.
