Unmatched Support. The Right Part. DIY with Confidence!

YES, WE'RE OPEN FOR BUSINESS! DDM is considered a life-sustaining company because we are an internet retail company that provides essential products. Due to the Coronavirus and the Delta varation, however, we are continuing our local order pickup policy at our West Chicago location. To pick up an order you will need to order first. The quickest way to do this is through our online shopping cart. There you can select the local pickup option. Or, you can call 630-293-1337 for assistance and to place your order. Once ordered, your parts will be available for pickup in the lobby of our north side front entrance. Longer items will be picked up on the south side loading dock.

COVID / DELTA VARIANT UPDATE! NO MASK, NO SERVICE! When picking up parts please wear a mask. If you don't bring one we'll gladly provide one. Please honor the six foot social distancing rule to protect yourself and our employees. Thank you for your patience and understanding as we all navigate this challenge together. More information is available on our blog titled DDM Adjusts to the COVID-19 Coronavirus. In the same article you will also find documentation and an answer to the question: "Is a garage door repair company a life sustaining business?"

PLEASE NOTE: COVID has interrupted global supply distribution chains resulting in unprecedented delays on incoming door and dock industry products. The result is limited availability of many products, three month delays on incoming shipments, and an inflationary rate of over 50% just this year on many of our products.
