Mars Supply is a 50+-year-old family owned and run business, which began with our grandfather Bernard Ungar's sheet metal shop in the 1920s and evolved into hardware, electrical supplies and appliances. In the 1940s, Mars Supply became the contractor-based arm of the business, which today specializes in heating and cooling products and hardware, roofing, glass block, fasteners and much, much more. Bruce and Joel Ungar now own and operate this small but multifaceted supply house, which is the epitome of hands on. In a world where problem solving, expertise and the hard-to-find are being lost on Earth, Mars is the place they're found.
