from The Grit Blueprint · host Grit Blueprint

Most people who sell doors have never seen one built. That is a problem. The product is more technical every year, the margins are tighter, and the warranty claims come fast when something is installed incorrectly.In this episode of Behind the Build, I walk through Magbee Contractors Supply in Winder, Georgia, with owner Bob Magbee. We tour the custom door shop and watch the process of making a door from start to finish.You’ll learn how doors are made on the Kval door machine, the Lamborghini of door machines. We cover the steps it takes to run a vertically integrated door manufacturing line at scale, including hinge routing, screw application, weather stripping, and threshold seal protection for the jobsite.You’ll learn what a split jamb is and how it comes apart in the field so casing can be pre-applied at the shop. We see a V-nailer in action, making brickmold hoops, and discover the benefits of assembling and applying these to the door unit in the shop instead of the field.Bob talks about why being vertically integrated matters for a dealer, how it solves warranty problems for builders, and why volume matters when you’ve made this kind of investment.This is the kind of behind the scenes content I wish I had when I started selling doors.
