The math just keeps going up from there. All that money is not going into the door itself. The entrance system is often composed of a single or double doors, side panels called sidelights and a decorative panel above the door called the transom. Entrance costs can add up fast. Each sidelight costs at least two thirds as much as the door it accompanies.
Transoms can cost far more.
Doors from the International Wood Products designer series available through his company are actually signed by the artist, Shelley Jurs. My technicians do a wonderful job installing garage doors, but I wouldn't let anyone but a finish carpenter install an entrance door. When replacing an entrance door, measurement is critical. They usually wind up cutting off either the top of the door, weakening the door, or cutting into the header above the door, weakening the structure. The average entrance door is 6 feet 8 inches high by 3 feet wide.
