A garage door spring replacement should cost between $175 and $225 for a single tension spring and between $250 and $300 for two tension springs. Most garage door companies carry a wide enough variety of spring sizes to cover most residential doors. As long as the proper amount of turns are put on the spring, there are more than one correct springs to use for any one door.
Torsion-spring doors have a drum-like pulley at each end of the metal rod that runs through the springs. Each pulley has a cable attached to the bottom of the door. The springs and pulleys are fixed to the rod so they all rotate together. When the door closes, the rod turns and winds up the springs, creating tension. When the door opens, the springs release the tension and turn the rod in the opposite direction. http://youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c
Squealing, screeching, or grinding noises from your garage door are usually indicative of a lack of lubricant or an accumulation of dirt or debris in the tracks. When removing debris, do not use harsh chemicals to clean the tracks. Once the track is clean, coat it with lubricant designed especially for garage doors, if possible. If you do not have access to this special type of lubricant, you can use WD-40 on the tracks and hardware. http://www.youtube.com/v/Z_eZc-kh40c&feature=youtube_gdata

"Our garage door wouldn’t shut on sunny days and the tech came out. He explained my options (swap the “seeing” sensor with the other, or replace them). He tried swapping and it was still an issue so he replaced them. In addition, he adjusted the spring because the company that installed it last year did not adjust it properly. He was here for about two hours and charged us for only the sensor replacement. Will definitely be using this company again! Highly recommend them. "

Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
6.1 It is time now to unwind the old spring that is not broken. A few warnings are in order. NEVER, NEVER, NEVER touch a set screw without first inserting a properly fitting bar into the winding cone! Also, do not use box or socket wrenches for the set screws. If the cone slips, the wrench could break your hand in 10 spots before unwinding completely. It's my guess that this is the number one cause of trips to the emergency room for inexperienced homeowners fixing or replacing their springs.
If you have decided to replace your springs, if you are sure your door had the correct springs, and if you are ready to buy new ones, we recommend that you measure your spring or springs following the instructions in Step 4 below. Measuring springs can be difficult; most individuals, even garage door technicians, sometimes have difficulty measuring torsion springs. Ordering incorrect springs wastes time and money. http://youtube.com/v/Z_eZc-kh40c
