Dock Building and Repair FAQs, 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.

The most significant factor in knowing whether to repair or replace your dock is the extent of the damage and its age. If you have minor cracks on a few boards and the dock is less than 15 years old, it'll likely be worth repairing the damaged part. However, it's time to replace this essential water feature if you have significant damage, such as rotting wood in multiple areas, warps or cracks in the dock supports, or a damaged foundation.

To maintain a dock, perform regular inspections for structural issues, clean away debris, and apply a sealant to wood components. This protects the dock from water damage and prevents premature wear and structural damage.

If you don’t want to rely on an anchor on land, you can also build dock posts. You’ll need to rent a water jet to blow out sand and silt from the lake floor in order to place the posts; it’s a complicated task that is best left to a professional.

Here are a few other considerations before you build, even if you're convinced you're in compliance with the law:

  • Are you damaging the environment? Bodies of water are often delicate ecosystems, and building a dock can be destructive and disruptive to the wildlife.

  • Are you blocking access? Lots of people like to use a lake, so you need to make sure your dock doesn't block public access to the water.

  • Can you enclose the dock? Just because you can build a dock doesn't mean you can build any dock you want. Some areas don't allow enclosed docks, for example.

  • Do you need to follow any specific rules or guidelines? Check with the National Oceanic and Atmospheric Association (NOAA) Office for Coastal Management for any guidelines you’ll need to follow, including size and type restrictions.
