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!
