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!
