Seaway Marine Group builds beautiful docks that are made to last.

Our state of the art dock building equipment enables us to build docks safely and efficiently, and we can drill into bedrock to set foundation piles from land or water.

We offer dock building throughout the St. Lawrence River and the Thousand Islands, from Henderson Harbor to Ogdensburg.

Stationary Docks

Our engineer designed steel pile stationary docks are strong and long lasting. We offer various deck options including concrete, wood and composite finishes to suit your budget and your needs.

Floating Docks

Floating docks allow flexibility with fluctuating water levels. Depending on your property’s location and exposure to wave action, a floating dock may be the best choice for your docking needs.

Our engineer designed floating docks constructed with spiral welded steel tubing are strong and steady on the water.
