Q: What is the difference between a DIY (do it yourself) garage door opener you buy at a big box store, and one that Markham Garage Doors would install?
A: There are huge differences between the machines. The Liftmaster brand we carry is the premium machine on the market; its solid one piece construction is crucial for longevity. This is much stronger than the 100 piece kit that comes with a DIY unit. The solid rail is the backbone of the opener. The angle is stronger, the electronics are better, the warranty covers the machine installed, and every door gets a tune up with installation. We service so many DIY openers that are still new and already broken. Our machines will give 15 to 20 years of trouble free operation!
