When our garage door was squealing upon opening and closing it, we tried WD-40 with no success. We noticed Angie’s list had a garage door offer through Aladdin Doors and called Aladdin. First, we were impressed with technician Dan who called ahead to let us know when he’d be here. Nice! He spent time in explaining the problem, replaced the rollers and lubed everything. Within six hours from start to finish, our door was working like new again. Great service!
