Our Business' History

Paul Douglas started this business in 1979 by working out of a small garage. His cousin, Eddie Cormier, came to work for him in 1984.  In 1998 Paul and his brother Mark Douglas jointly purchased Formal Oil Co. from Russ Malone.  A few years following, "5 M Heating" was aquired as well.  In 2007, Paul's son, Scott Douglas, joined the family business after graduating from New England Fuel Institute and receiving his license in oil burning equipment. Since 1979, P.R. Douglas Co. Inc. has transformed to include six service vans, two fuel oil delivery trucks and a 6,500-square-foot shop.
