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!

Quick service
Kudos to Jeff Harris
We have Dor-co garage door since we bought our new house. Never got any issues with it. It was no brainer to call them for service when we have door bent after a little accident. Jeff came next day… Read more We have Dor-co garage door since we bought our new house. Never got any issues with it. It was no brainer to call them for service when we have door bent after a little accident. Jeff came next day after call and took care of everything. Door is back to working again. Great level of professionalism and tons of experience made his hard work look easy. Another happy customer of Dor-co.
Excellent service provided

Technician Jeff H arrived in less then 30 minutes and did an outstanding job assessing the very old garage door system (probably 50 years+) and was able to fix the broken bearings and cables in less then an hour. He then checked over the remaining parts of the system and cleaned and oiled all the parts so the door operates smoother then it has for years. Very pleased with our Dor-Co service experience.
Efficient service
The service was quick and efficient. Jeff showed pride in his work. Not only did he answer all my questions but gave me advice to help prevent problems in the future.
Great Service
Called Dor-co for service & they came out that day & explained what needed to be done. As our garage door was still functionable they gave us a follow up date for the repairs for a few days… Read more Called Dor-co for service & they came out that day & explained what needed to be done. As our garage door was still functionable they gave us a follow up date for the repairs for a few days later. Jeff showed up right on time. Our door works like a charm. We have had other companies come out & they always said our door was noisy because it was a heavy wood door. Jeff has this door working smoother than glass & it is so quiet when operating. It wasn’t this smooth & quiet since first installed!
Great Company!
From Sales with Dan to install was very professional and thorough! Great product and install person cleaned up nicely. Thankyou!
