Quality
We are committed to creating exceptional products, never sacrificing quality. The doors are produced with precision from materials that are greater than industry standard.

We serve our customers to the highest standard and their satisfaction is our measure of success. Diamond Doors aims to be professional, helpful, and sincere in their customer service.
A Message From The Founder
Building bifold doors was something I did to help support my family during the off season while working as a commercial pilot. Diamond Doors was a company born because people had a need, and I knew I could provide what they needed: bifold doors engineered for quality, convenience, and longevity.
In the open sunshine, with my previous steel manufacturing experience and some ingenuity, I built my first bifold door. It took me a month. Once I had built my first door people started coming to me for help. I started building hangar doors for guys I flew with, then bifold doors for machine sheds and barns. Living in an agricultural community continued to bring new opportunities.
There came a time where I had to choose. Do I continue flying commercially or build doors full time? I could not do both. That is when I decided to create Diamond Doors. My wife thought the name had a nice sound to it. We went full time manufacturing in 1998, building custom bifold doors for hangars, machine shops, quonsets, storage buildings, architectural projects, and industrial applications.
My idea had been that when we build a door, the buyer should be able to install it with ease. Often customers would have to hire extra help to put up a door. It would take days to install. There were many components to assemble. This cost them extra money. Why not have all that assembly done in manufacturing? The Diamond Door comes completely assembled, pre-wired, and all electrical components are tested before it goes to the customer. It should take about 3 hours if you have never installed one before.
Diamond Doors uses a triple internal truss design, high strength tubular steel, maintenance free hinges, a UL 325/ CSA 22.2 certified electrical box, and aircraft grade lift cables with a 10X safety factor. There are many industry leading features that come standard on a Diamond Bifold Door because we want our customers to experience quality and have an exceptional door.
We operate on the values of honesty and integrity. It has never been about the money for me. Our measure of success has always been customer satisfaction. We serve our customers long after the sale is made. That is what I have told my sons. As a family business they have helped our company grow and become an industry leader. I would never have dreamed the Lord would bless our venture in the ways He has.
As long as people continue to ask for our doors, Diamond Doors will continue making them.
Sincerely,
Dick Suderman

2007
Humble beginnings. Brothers Jim and Terence Suderman working in the original office building.
2007
Founder Dick Suderman and his wife, Agatha. The couple worked together for many years to help grow the family business. We have Agatha to thank for the name Diamond Doors. Dick says, “She thought it sounded nice, especially when reception would answer the phones, it had a nice ring to it and represented the quality of our doors.” Agatha has since retired from day to day work at Diamond Doors, but we still see her from time to time (and are grateful when she brings homemade treats).
2009
