Do You Need A Garage Door Repaired Or Installed?
Broken Garage Door Spring Repair
There are two types of springs on garage doors:
Extension springs– Stretch above the parallel to the horizontal tracks for garage doors. Springs are also attached to cables that are anchored to the bottom of the bracket of the garage door. Unlike Torsion springs instead of winding these springs. Extension Springs apply resistive force as the springs stretches storing mechanical energy that is used to open the garage door.
Torsion springs– work by twisting or torsion and store mechanical energy when twisted. Special instruments are used to wind the coils of the spring which applies torque to the center shaft.

Professional Installation
Jay - Ottawa, IL
We were overwhelmed with how the curb appeal of our home improved. The Amarr garage doors are made of high quality materials. Each door is custom made per client. * As the saying goes, “You get what you pay for. “ Amarr doors are not cheap, but the quality and stability of doors are well worth the price. * Dan and John did an excellent job installing. Installing a high quality product requires top rated installers. Could not be any happier with the service provided by Doors Unlimited.
The Best!!
