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!

Company response:
As I explained to you there is a nation wide shortage on many Garage Door parts at this time. Once the product arrives we will contact you and make arrangements to get the parts replaced at your earliest convivence. I was off for the day but did come into the office to get you as much information as I could the same day. I also called and texted you from my personal phone so that you were able to contact me at any time. I sent you copies of the email we sent to our vendor as per your request showing that we did order the parts the same day we found out about the damages. Your review seems to have left out that we are continuously working to rectify this issue with the manufacturer. Thanks, and I look forward to meeting with you on Monday to discuss this further.Areas served by our team of professionals
