Sean had done many welding jobs for both me and for our snowmobile club. He has all the right equipment for mobile emergencies or in house repairs. All of his work is professional and top notch.

Great welder, a golden arm! I think he does more industrial projects but I asked him if he could weld some brackets for my lawn mower. Not a problem for him. He is professional, thorough, and quick. His welds are beautiful!
