Get matched with top dock building and repair pros in Sumner, IL

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.

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.

It is possible to build your own dock, especially for simpler projects like a small floating dock, provided you are an experienced DIYer. However, dock building is a complicated process, and hiring a professional is recommended for larger, more complex projects that involve installing pilings or engineering a suspension structure.

A professional dock builder will have the necessary tools and skills to set post foundations, ensure proper anchoring, and build a safe, durable structure that can withstand marine conditions for decades. They are also knowledgeable about local regulations and permitting requirements. In some areas, it is illegal for anyone without a marine construction license to build a dock. Hiring a professional helps avoid these potential legal headaches and ensures the project is completed safely and correctly.

The cost of a new dock can range from $3,000 to $30,000, depending on the extent of the project size, location, and additional features.

For example, a boat lift can range from $1,000 to $8,000. The ladder you'll need for your dock can be anywhere from $100 to $800, not including installation. In addition, the decking you'll need for your dock can cost between $15 and $30 per square foot.
