Dock Building and Repair questions, answered by experts

Yes, professionals can replace damaged flotation devices to maintain proper dock buoyancy.

Most dock repairs take 1-5 days, depending on the extent of the damage and weather conditions affecting the work schedule.

Bulging walls, cracks in the seawall's top or side, and the appearance of a seawall "pulling away" are all signs that you need repairs or reconstruction. The area around the seawall can also provide clues. For instance, you may notice water bubbling over in areas of your yard if your seawall has holes or cracks. The soil around the seawall may also appear to be sloping or sinking.

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.

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