Dock Building and Repair questions, answered by experts

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.

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.

Yes, many professionals handle necessary permits to ensure legal compliance.

Building a dock is a complicated and time-intensive project, so professional builders typically take several weeks or several months to complete dock construction. Smaller docks in relatively shallow water may take two to four weeks to complete, while large or ornate docks in deep water could take up to six months. The timeline depends on the size and type of dock you want, the weather conditions in your area, and how ornate the construction needs to be. Your dock builder should give you an estimated timeline for construction along with your quote.

In most areas, dock builders need some type of license. In some states, only a general construction license might be necessary, while a marine construction license is required in others. You can check online to see which is mandatory in your area, and then you can use Angi’s contractor licensing tool to make sure the company holds the proper license. Since dock construction is inherently dangerous, confirm with your builder that they are fully insured for everyone’s protection.
