We replaced a double entry door for one of our patios. The installation took longer than expected because the installer wasn’t made aware that our foundation is ICF (Insulated Concrete Foundation). We explicitly mentioned this to the salesman. The door is great, works well and has low E glass with no jail bars like the old one. The door should last as long as the house. Two downsides: We waited for months after the order to get the door and we feel it was a little expensive. Be prepared when you do your shopping, especially if you have the in-home experience. Make sure you tell the salesperson all of your requirements and they take note. The installers were professional and, as expected, did a thorough job on the install. We would recommend Folkers, but be prepared to wait awhile.
