Owning waterfront property comes with both opportunity and responsibility. A dock or seawall is not just a luxury, it is a smart investment in shoreline protection, functionality, and long-term value. Whether you're envisioning a place for boating or aiming to guard against erosion, understanding the process is key.


This guide walks you through the five essential steps of building a dock or seawall, along with a few extra tips to help you plan confidently and avoid surprises.


Step 1: Site Evaluation and Consultation

Every project begins with a thorough site assessment. A contractor will evaluate your shoreline, water depth, erosion risks, and local conditions to determine the best design and materials.

For example, calm water may allow for wood or composite materials, while deeper, rougher areas may require reinforced concrete.

 

Why it matters: These early insights shape the entire project, from permitting to performance. Duncan Seawall customizes every build to match your property’s specific needs.


Step 2: Permitting and Regulations

Waterfront construction often requires approval from local, state, or federal agencies. In Florida, this could include the DEP, Army Corps of Engineers, or local environmental boards.

 

What to expect: Permit timelines vary, and larger or environmentally sensitive projects may take longer. Partnering with a contractor like Duncan Seawall ensures compliance and saves you the hassle of navigating complex paperwork. Download our permits guide for additional tips and insights.


Step 3: Design and Materials

This is where your vision comes to life. Your design should reflect both your lifestyle and the unique demands of your shoreline.

Common materials include:

  • Wood: Natural look, higher maintenance
  • Composite: Durable and low-maintenance
  • Concrete: Ideal for seawalls and high-impact areas
  • Vinyl: Corrosion-resistant and cost-effective

 

Step 4: Construction Process

Once permits and plans are in place, construction begins.

 

Typical phases include:

  • Site prep and foundation work
  • Material installation
  • Drainage and structural reinforcement
  • Finishing touches like decking, rails, or landscaping

Timeline: Smaller docks may be completed in weeks. Larger seawalls can take several months depending on scope, weather, and permitting.


Step 5: Final Inspection and Turnover

After construction, inspections confirm the build meets both safety and regulatory standards. Duncan Seawall provides you with care instructions, warranty details, and maintenance tips to protect your investment for years to come.
