It is important to replace your home’s front entry door if it shows any sign of damage.  If your door is scraping the floor when in use, not shutting properly, or allowing drafts to pass while closed, you need an exterior door replacement.  Having a new front entry door installed (or any type of exterior door installation) will help lower energy bill costs by keeping the temperature regulated inside the home and can add to the value of your home by improving curb appeal.  The best way to tell if you have damage to any of your home’s exterior doors is to have a professional door replacement contractor come out for a quick inspection.
