According to Home Advisor, the Barn Door prices range from $200-$1000 and installation can cost the same. Having said that, the price of a custom crafted wood barn style garage door will be substantially higher. My advice is that your decision to install a barn style garage door should not be influenced by price. Shop for something that goes well with your home. Aesthetics and Durability is more important than Price, when it comes to Barn Style Garage Doors.
