...LOVE THE PRODUCT, super high quality! Shipping to Alabama was great! Love my "Great Northern Dock" stairs down here in the south!

I worked with Gretta ordering the dock stairs descending into the water. Since I could not see the product, I was a little nervous ordering on my own. Gretta helped answer all my questions, and helped me figure out the best system for my situation! I don’t think I would have purchased had she not been such a great help. LOVE THE PRODUCT, super high quality! Shipping to Alabama was great! Love my “Great Northern Dock” stairs down here in the south!

As one of the larger dock installation companies in southern Maine I have worked directly with Great Northern for years. Their product is unmatched in Quality, Longevity and Look. There is no application or shoreline their docks can’t accommodate. Not only are Great Northern Docks in a class by themselves they are also the most installer friendly dock systems on the market. My dock business has been exclusively with Great Northern for years and they will always be the only company I will work with. From start to finish you will never be disappointed investing in a Great Northern dock system.

I purchased a new dock this season from Great Northern Docks and was extremely happy with the quality and service. From the initial site review, where the team came out and created options on paper, to the prompt delivery, everything went smoothly. When my installers were short some pipe, I called and GND quickly cut a 20’ pipe into two pieces and had it ready to go within the hour for no extra charge. They also gave me a refund for a few extra pieces that I had left over after installation.The dock itself is great looking, well constructed, and very functional for fun summer days on the lake; whether boating or just relaxing on the dock. Thank you GND!

Lindsay and the team at Great Northern Docks provided excellent support and guidance in the entire process of selecting the appropriate dock that meets our needs and budget. Assembly was straightforward and the quality of the material as well as the craftsmanship was excellent. My wife and I are looking forward to adding additional accessories next year.
