Dock Building and Repair questions, answered by experts

The cost to build a new dock can range widely, typically from $5,000 to $65,000, with an average cost around $15,500. The final price depends on several key factors, including the dock's size, the materials used, the complexity of the installation, the depth of the water, the type of dock being built, and whether it is in fresh or salt water.

Common choices include pressure-treated wood, composite decking, and aluminum for durability and low maintenance.

Cedar wood is the best choice for a hardwood dock, as it is rot-resistant and does well in the water. Pressure-treated pine and spruce are two other solid options. Alternately, composite or waterproof plastic are materials commonly used for docks, and are frequently used in prefabricated kits.

You will likely need a permit to build a new dock or add to an existing one, especially if it's a permanent structure. Permit requirements vary by location, as they are typically set by local municipalities, counties, or cities rather than states. You should check with your local government or building department to determine what paperwork is required before you begin. In many areas, you may need multiple permits, including general construction permits and those designed to protect local marine life. Additionally, if you are part of a homeowner's association (HOA), they may have their own rules regarding docks, such as minimum distances between neighboring docks. It's best to check with all relevant authorities (city, county, HOA) to ensure you are in compliance. A professional dock builder can often handle the permit-pulling process for you.

Costs depend on dock type, size, materials, water depth, and labor.
