New DIY Instructions App for Cell Phones

Posted May 28th, 2015 at 11:20 am by Dan Musick


We’re happy to introduce our new app available for $1.00. It contains a wealth of technical information on garage door springs and spring conversions, garage door and opener maintenance and repairs, high lift conversions, low headroom solutions, weather seals, and dock leveler repairs.

One of our software developers, Nate Rupsis, recently re-organized our tutorials library. Afterward, and in keeping with the times, he formatted the page as an app to fit the more popular smart phones


This app has grown out of my 36 years in the garage door business.

I initially worked at the Overhead Door Company in Elk Grove Village, IL, the largest door business in the industry. In January of 1979 I began as a service man for the owners, Harold Tonnesen and Jim Weeks. In subsequent years I built an audio visual training library while serving as training coordinator for the company. During that time the company left the OHD franchise and changed their name to Door Systems. The owners also opened Northwest Door, a new sectional door manufacturing facility in Elgin, IL, where I developed training and manufacturing support materials.

In the eighties I developed a company with three divisions: (1) The sale, installation and repair of residential and industrial garage doors doors and operators, (2) The sale of garage door hardware, and (3) Training for building engineers and facilities maintenance personnel to repair their doors and operators.

In the early 90’s I sold Dortrak, the installation and repair company, and kept the other two divisions. These weren’t generating enough income to feed and shelter my family so I went to work for Harold Poling at Area Door in Elgin, IL for about 15 years. He agreed to let me grow my own business on the side as long as I didn’t work in his service area, which I honored.

While working there I grew the service and installation business. My older son, Erich, loved computers and the internet and in 1997 he developed and posted our website. In 1998 we began posting online repair instructions for various types of overhead sectional garage doors and openers.

In the early years of the Web we didn’t earn enough to justify paying to post the site. We joked about being a .org. One of our major stockholders suggested I close the business. We survived the year 2000 dot-com collapse – little invested, little lost.

From there the internet parts business grew with the installation and service business, and several years ago I left Area Door to work full time in this business.

Earlier this year we sold the installation and service company to Matt’s Garage Doors. He’s doing better with that part of the business than I ever did.

Now, as DDM Garage Doors, Inc. we continue to provide garage doors, parts and hands-on training. As DDM Web Services, Inc. we develop tutorials and software for the garage door industry, for building engineers and facilities maintenance personnel, and for the DIY market.

These programs have also inspired many entrepreneurs to start their own garage door repair companies, and for over a decade garage door repair technicians have benefited from our free online instructions and software.

God has blessed me with work that I love. I wish the same for everyone who works on all the different types of garage doors and openers. Life’s too short to endure work you hate. A friend of mine in my early years at Wheaton College advised, “Determine what you enjoy doing, and find someone to pay you to do it.”
