John and his extremely professional crew has helped me tremendously here at Old Brockway Golf Course over the last decade and a half. I would highly recommend this company for any and all diving services, pipe replacement and pump repair. Their dedication and enthusiasm is second to none especially in emergency situations. They also have a well equipped and staffed fabrication shop to make anything I need. When my turf is on the line this is my first phone call.

I have worked with John and his company for the past three years and have found him to be reliable, honest, very capable, and hard working. As the operations manager at Ski Run Marina, I am an engineering perfectionist and have truly enjoyed working with John. When other contractors dont want to spend the time to fix complicated problems, John is able to provide economical and worthwhile solutions. He is adept at working on several projects at one time, from small to very large.

As a Project Superintendent for Wester Water Constructors, I have worked with Advanced Marine for about 5 years. We used them on a couple of complex projects requiring some work in SF Bay. They are timely and professional in work and documentation. They offer one-stop shopping for underwater construction & repair - providing engineering, fabrication, diving and installation services. They also helped us through the permitting process.We will use them again if we need this type of work in the future and would recommend them highly.

Very professional and knowledgeable in many aspects of construction.
