Count on LiftMaster automatic garage door openers
Garage doors are typically the largest moving part of a home or building. Without an automatic door opener, they can be quite difficult to open or close. At Dor‑Co Garage Doors, we believe choosing the right door opener is just as important as the door itself. That’s why we recommend LiftMaster door openers to all of our customers.
LiftMaster products are number one in the industry. Made by the Chamberlain Group, these automatic door openers are built to last. Their motors are powerful yet quiet, making them a great choice. LiftMaster openers can be customized with a wide range of accessories including smartphone connectivity and security systems.
To see which opener is best for your commercial or residential garage door system, please see the specifications listed in our door opener section. You may also visit one of our showrooms – our experts will be happy to provide you with personalized advice!

The Service Technician (Larry) showed up the next day (St Clair Township) and replaced both springs in an extremely efficient manner, then did an overall maintenance of the hardware on both Doors. We were extremely pleased with the overall experience and how proficient and personable the Technician was to interact with. Highly recommended.

Jeff Harris came out the same day I had called about getting garage door & opener. Jeff took the time to show the different door openers & different garage doors. Very good at what he does. The door opener we had wasn’t working. Jeff can back the following week to install the new garage door opener so we could use it till the garage new garage door came in. Two people came a few days ago and installed the new garage door. The new door looks good. The installers were good & did a nice job.
