These garage doors are low maintenance and come with 10 years warranty that includes: cracks or rust. We removed and hauled away the old doors and hardware and installed their new Amarr garage door with all the new parts: Tracks, Torsion tube, springs (double system for the 2 car garage), Cables, Silicon Rollers, Hinges, Drums and some other parts. Since they already had a garage door opener all we had to do is to plug it to the new door and make some minor adjustments that included: force adjustment, switch limit and sensors adjustment to it.
