  • Jeremy Mann

    "I recently had 2 boats detailed by Upstate Marine and my experience was fantastic! Adam and Chad were immediate to respond to my inquiry and I had a quote within minutes. They were professional from start to finish, they even picked up the boats and delivered them back to my boat slip when finished. Their work speaks for itself...Great Job Upstate Marine! HIGHLY RECOMMEND!"

  • Colton Knox

  • Josh Beams

    "Upstate Marine went above and beyond my expectations. Cant say enough good things about the communication between Adam and myself. They took ample time to do a lake test and many other odds and ends things that made the whole experience awesome.I drove here all the way from Louisville Ky. and when its time to upgrade In the future, this is definitely where I will be coming.Thanks Adam and Chad so much for taking so much time to make sure the boat was perfect."

  • James Henderson

    "Fantastic job. Volvo looks better than when it was new. Owners and employee's were very nice. Reasonable prices."

  • Jim Haynes

    "I had Chad pick up my boat from my dock, and it was a mess from being out of the country for two years. The cleaning they did on the pontoons and the carpet and compartments was nothing short of remarkable, even repairing some rotted carpet at the back of the boat. I cannot recommend them highly enough!"
