As your house ages, paint and other building materials age and break down as well. The same goes for your garage door. Many older garage doors are made of wood and tend to age rapidly when the paint fails and the underlying wood gets wet and weathers. Then the door looks bad and can often sag noticeably as the wood deteriorates. When this happens, not only does the door look bad, it may become a safety problem if the door becomes structurally weak. Remember – your garage door is above your head when the door is open. This could pose as a safety hazard to you and your family and the best option would be to get your garage door repaired or to get a replacement garage door. Sometimes if a garage door looks visually deteriorated, but otherwise safe, the garage door can be painted and can last a few more years. Then, you may want to save your money for a replacement at a later date. Most modern garage doors are made from steel. When properly cared for, a steel door can often last a lifetime – remaining safe and beautiful for decades. If you have a steel garage door that just needs paint, you can often make it look almost as good as new with a new coat of paint.
