Dock Building and Repair questions, answered by experts

Repair costs range from $500 to $5,000, depending on material type, structural damage, and labor. Extensive piling or decking replacements increase the price.

Boat docks need maintenance every year. Get an inspection at the end of each warm weather season, and remove the dock from the water if possible (if it’s made of wood) when not in use. You can also treat the wood to lessen the impact of moisture damage.

Docks can last between 20 and 30 years, provided regular maintenance has been performed. Upkeep tasks like staining your dock annually to prevent water damage, repairing broken elements quickly, and using dock covers regularly will help extend your dock’s life. Your dock is likely nearing the end of its lifespan when it shows signs of rot, rust, and foundation damage.

Minor repairs like replacing boards can be DIY-friendly, but structural or underwater repairs require professional expertise.

Regularly inspect for structural issues, clean debris, and apply sealant to protect from water damage.
