Find top rated water dock builders in your area

EZ Dock modules range in price from a few hundred to a few thousand dollars, depending on size and additional features. These plastic- or aluminum-framed sections snap together quickly, giving you a lightweight, flexible system that’s easy to move or expand. Add-ons such as rails, ladders, or integrated lifts push the total toward the higher end of the range.

Dock repairs average $3,215, but your bill will vary depending on the scope of work. Fixing structural damage, swapping out rotted boards, or treating rust all add labor and materials. Location, dock design, and the products you choose drive the final price, and hidden issues uncovered during the job can nudge costs higher. Budget a little cushion so unexpected repairs don’t leave you scrambling.

Swapping a wood frame for aluminum, paired with composite decking, can increase your build by roughly 20% to 50%. Material choice is the quickest way to change the bottom line, but you can still mix and match—think aluminum posts with wood or plastic planks—to hit the look you want without breaking the budget. These combinations enhance durability while allowing you to tailor the final design.

You can tackle a simple floating dock on your own if you’re comfortable with tools and local codes. Anything that involves driving pilings, engineering a suspension system, or working in deep water is best left to a licensed pro who has the equipment and permits. DIY where it’s safe and straightforward; call a specialist when structural integrity or safety is at risk.

Most jurisdictions require a permit—and sometimes several—before you install a permanent dock. Ensure you check city, county, and HOA rules early and confirm whether state or environmental agencies also need to approve. Securing paperwork up front keeps the project legal, helps you avoid fines, and prevents delays once construction begins.

Local rules set the maximum length and layout. Many areas cap a dock at one-quarter of the waterway’s width to protect navigation, shoreline habitat, and public access. County, city, or HOA boards may also regulate width, decking materials, and rail height. Before you sketch a design, review those codes so your plans sail through permitting.
