Docks are essential for waterfront living in Jacksonville, Ponte Vedra, and along the St. Johns River. Over time, exposure to sun, salt, boat wake, and moisture causes wear. Many docks built decades ago used untreated wood or non-marine materials that were never designed for long-term performance in these conditions.
When problems appear, homeowners often ask the same question: Should I repair my dock or replace it entirely?
The answer depends on the dock’s structure, materials, and overall condition. This guide explains how to make the right decision and why modern docks built with composite decking and marine-grade pressure-treated lumber outperform older installations.
When Dock Repair Makes Sense
Dock repair is usually appropriate when the underlying structure is still sound.
Repair May Be Enough If:
- Damage is isolated to decking boards
- Pilings remain stable and properly embedded
- Framing members are structurally solid
- Hardware corrosion is minimal
- The dock is less than 15 to 20 years old
Replacing worn decking with composite materials is a common and effective upgrade that improves safety and reduces maintenance.
Signs Dock Replacement Is the Better Option
Replacement is often the safer and more cost-effective choice when the dock was built with inferior materials or has widespread structural issues.
Replacement Is Recommended If:
- Pilings show rot or severe marine borer damage
- The dock shifts or moves underfoot
- Framing members are cracked or failing
- Multiple repairs have already been attempted
- The dock was built with untreated or non-marine lumber
Attempting repeated repairs on a failing structure often costs more long term.
Material Quality Plays a Major Role
Older Dock Materials
Many older docks used:
- Untreated lumber
- Interior-grade wood
- Galvanized hardware not rated for saltwater
These materials deteriorate quickly in coastal environments.
Modern Dock Construction
BOSS Outdoor builds docks using:
- Marine-grade pressure-treated lumber for structure and pilings
- Composite decking for walking surfaces
- Marine-rated hardware
This combination delivers strength, longevity, and low maintenance.
Cost Comparison: Repair vs Replacement
While exact pricing varies and is based on the width and footage of the dock, typical ranges include:
- Minor dock repairs: $1,000 to $10,000
- Decking replacement with composite: $5,000 to $25,000
- Full dock replacement: $15,000 to $40,000 or more
A professional inspection determines which option provides the best return on investment.
Winter Is the Ideal Time to Evaluate Your Dock
Winter offers:
- Lower water levels for better inspection
- Reduced marine growth
- Easier access to structural components
- Better planning for spring construction
Scheduling an evaluation now avoids delays during peak boating season.
Why a Professional Marine Inspection Matters
A qualified marine contractor assesses:
- Piling embedment depth
- Structural load capacity
- Framing integrity
- Hardware condition
- Long-term safety risks
This ensures you make an informed decision rather than guessing.
