We ordered pre-hung doors and bi-fold doors for our basement. Due to variations in the basement ceiling height (boxed in duct work), the height of the doors needed to be customized. The staff at Windsor was very professional and helpful. The doors needed to be ordered in and customized in the shop. We were notified by phone at each step in the process. Windsor is more expensive than purchasing doors from big box stores, but the additional customization service is worth the money. I highly recommend Windsor!
