The Complete Handbook of Doors
For professionals, builders, and businesses who need to specify, install, maintain, and profit from doors
by Alumigogo Books
non-fiction
The professional reference for specifying, installing, and maintaining doors—with real guidance on codes, troubleshooting, and business opportunities.
About this book
Doors are infrastructure. They secure buildings, separate environments, control traffic, and define accessibility. Yet most professionals source them from incomplete spec sheets, YouTube videos, or trial and error—wasting time and money on rework.
This handbook is built for the people who do this work: architects choosing between hollow-metal and solid-core for a commercial renovation; contractors installing 40 doors on a multi-family project; facility managers diagnosing why a fire-rated door won't close properly; hardware retailers advising customers on hinge capacity and frame tolerance; and entrepreneurs looking to build a door-service business.
You'll find practical guidance on how doors actually work (and why the specs matter), how to choose the right configuration for your building type and code environment, how to install them correctly the first time, how to maintain and troubleshoot the most common failures, and how to position yourself as a professional in a category where most competitors guess. Grounded in real-world problems and written by someone who understands the professional context, not marketing.
Reader Reviews

★★★★★I wish the installation chapter had more diagrams showing common frame configurations, and the troubleshooting section could use a flow chart for diagnosing hinge vs. closer problems. That said, this is the most practical door reference I've found—the code compliance section alone saved me hours on a recent commercial project, and the business opportunities chapter gave me real ideas for expanding my service work.

★★★★★Finally, a door book written for people who actually install and maintain them. The Chapter 1 explanation of why specification matters before you buy was exactly what I needed to explain to a client why a $40 hollow-core door wasn't going to work for their server room. Clear, concrete, no fluff.

★★★★★Solid foundation for someone new to the door business. The types and specs chapter is thorough, and I appreciated the real-world examples. Some sections felt a bit basic for experienced contractors, and I would have liked more depth on commercial fire-rated systems. Still worth the read if you're getting serious about doors.

★★★★★This is the book I'll keep on the truck. Every chapter answers actual problems—not vague tips. The maintenance and troubleshooting section has already paid for itself by helping me diagnose a door that was failing code because of a closer adjustment I could do in 10 minutes instead of replacing the whole assembly. Exactly what a professional needs.

★★★★★Outstanding reference. I run a hardware retail business and was struggling to educate customers on why they shouldn't just pick a door by appearance. Chapter 2 on specifications and Chapter 3 on choosing the right door have become the foundation of how I position products and serve my customers. The glossary alone is worth having this book on hand.
