It’s a matter of preference. Steel doors are low maintenance, can be painted with latex-based paints, possess more extended warranties, and, with insulation, are more energy-efficient. Wood doors are great for curb appeal, can be stained, and come with unlimited options. Cal’s Garage Doors sells plenty of both, including options from manufacturers like Clopay, Amarr Garage Doors, Northwest Door, and Carriage House Doors.
