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!

Dear Sirs:
On Monday, October 5, 2009, we had a service call scheduled for our garage door. About twenty (20) years ago your company installed our garage door and I must say that one (1) call in twenty years is excellent. Your service technician Dan Watson arrived and looked over the issue. I must say that it was an extreme pleasure to finally have someone come in and look over the situation and make the proper adjustments and repairs that were required. Dan was extremely efficient, pleasant and professional and I just wanted to take the time and commend him on his work.
Thank-you once again for the service rendered and be assured that I will recommend your services when required.
Take Care and Be Safe
