Boat docks need maintenance every year. Scheduling a comprehensive inspection at the end of each warm weather season prevents minor issues from turning into major repairs. Annual upkeep—including cleaning, repairing defective parts, and applying protective treatments—preserves the dock’s structure. Consistent maintenance ensures safety and prolongs the dock’s durability while minimizing repair costs over time.

In most cases, yes, pressure washing a boat dock is a great idea. Pressure washing costs $210 to $450, removing algae buildup, stains, and debris, helping to keep your dock in excellent condition. However, some materials, such as vinyl and certain composites, may not be suitable for pressure washing. Always check the manufacturer's recommendations before proceeding.

On average, a boat dock lasts between 10 and 20 years. Performing regular maintenance and reapplying protective treatments as needed will help extend the life of your dock. It's important to address issues promptly to prevent them from becoming more significant problems. Keep your dock clean and free of algae and debris, and ensure you use the proper protective products for your dock's materials.
