Beginnings

Tandem Built LLC roots begin with Thomas Mimidis Sr. opening his Garage Door company, Belle Vernon Door Sales, back in 1959.  The Company grew from not only providing Garage Door Service, but also providing Entrance Door, Storm Door, Window Service. In 1999 His son, Thomas Mimidis Jr. took over the Business and expanded into providing even more products such as, Retractable and Aluminum Awnings,  Custom Sheds & Decks. In 2019 Tom Jr. was introduced to Stephen Thompson who has incredible carpentry vision & unique skills. Seeing that the business had grown from its Garage Door Roots into many more areas of service, both Tom & Steve decided to bring their skills together and form Tandem Built LLC.
