There are a couple reasons why you may want to replace your existing door. The first is if the door is warped enough that it doesn’t function well, or if it’s too old to restore.   The second is if you’re deciding to remodel your home or change other aspects of the exterior, like paint, roof materials, or windows. Replacing the front door keeps everything cohesive and beautiful. It may even add to your home’s value, and it improves the curb appeal.
