PSI Marine delivers dependable inland and island marine construction, transportation, salvage, and demolition services with safety, craftsmanship, and integrity at the core of every project.
Our Founder
Pat Patch founded PSI Marine in the 1990’s. He and the team have built docks, boathouses, foundations, and drilled wells for decades and has earned a strong reputation on the St. Lawrence River as the best in the business.
Pat and his wife Brenda are still involved in the day-to-day-operations of the company as we carry their legacy and devotion to excellence in marine construction moving forward.
What makes PSI Marine stand out
During the dock building process, we use a specialized method when driving our piles that ensures they do not lift, even in the harshest weather. Pat Patch developed this process over years of experience building on the St. Lawrence River, and our team follows these methods for all projects.
From the beginning of your dream project to after completion, we are here to ensure you have a great customer experience and a lifelong partner on the River. We at PSI Marine are proud to stand by our work.
