I could not be happier with the service from Precision, and Tom, especially. About a year and a half ago I called to have my garage door that was sticking, repaired. Tom came out same day and replaced, adjusted, serviced all moving parts and got it going smoothly. He has since come out within hours of a call to adjust and keep (what might not be the best) door, (originally installed by someone else), operating well. I recommend Precision and Tom with complete confidence.

A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]

Our technicians are specially trained to handle a variety of garage brands, styles, and configurations. After arriving at your home, a Sears technician will diagnose the problem and walk you through the options for fixing it. Next, the technician will make any necessary adjustments or replace broken parts to ensure the door can be operational once again. We always attempt to complete repairs the same day of service, and your satisfaction is guaranteed. Our representatives are standing by for your call and are happy discuss pricing options.
The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.[4]
After you’ve ordered your new garage door, we’ll perform a site inspection to confirm your door size. We’ll contact you to schedule the installation, and our professional installers will do the rest. They’ll deliver your door, take down the old door, reconnect your opener if there is one, seal your perimeter and provide a final walk-through where they’ll clean up the area and haul away your old door. Additional fees for haul away may apply in some markets. We are happy to provide answers to questions you may have at the time of your garage door and opener installation.
