Locating a contractor - there are many professional overhead garage door companies. It is always advisable to contact at least three different agencies and request a bid or quote for the work. Be sure that each quote includes the costs for a few different types of doors, any installation fees, and the cost of wiring the electronic openers. Standard prices range from: http://youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c

Annual maintenance. Make an annual check of all nuts and bolts on rails and rollers to make sure they’re firmly tightened. Check the condition of all cables to make sure they’re not worn or frayed. Lubricate rollers and springs with a garage-door lubricant (see How to Fix a Noisy Garage Door for maintenance and problem-solving tips). The door should operate smoothly and be properly balanced. Check the balance by disconnecting the opener and lowering the door halfway- the door should hold its position. If it doesn’t, adjust the spring tension or replace the springs.
Whether you're planning on moving in the future or you're fixing up your forever home, replacing a garage door can provide an excellent return on investment and boost your home's resale value. According to Remodeling magazine's 2016 Cost vs. Value report, garage door upgrades provide a nationwide average return on investment of over 90%, making it one of the top five home improvement projects.

10.5 If the spring comes loose from the cone at about 6 turns, you are probably winding the spring backward because the springs are on the wrong sides. Switch the springs. Otherwise, after winding the torsion springs, you will need to stretch the springs and secure the winding cone. First, mark the shaft 1/4" beyond the winding cone with tape or with a file. We stretch the springs because the shaft floats horizontally between the flexible end bearing plates as the garage door operates. Although this may be as little as 1/4" the binding of the coils as the door closes often keeps the door from closing completely, especially when the springs and bearings are dry and need lubrication.
If you are not sure if your door had the correct springs, we recommend that you weigh your door using an analog scale. From my own field experience I would estimate that at least 10% of the doors have the incorrect springs on them. In addition to this, most manufacturers spring their doors using a 20 pound window. We like to improve the garage door balance.
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings. https://www.youtube.com/attribution_link?a=Z_eZc-kh40c&u=watch?v=XXXXXX&feature=share
If you have a single-car garage, an extension spring will do the job. If you’re looking for a smoother motion and an ability to lift heavier doors, you may be better off selecting the torsion spring option. And if you have a two-car garage, your door will likely be too heavy for an extension spring. In this case, the torsion spring is the better choice.
If your door feels heavy, it is likely that your springs have started to wear down and are no longer capable of bearing the weight that they once did. Now, don’t worry, just because a spring is starting to lose its strength doesn’t mean it will snap at any moment. However, simultaneously, a weak spring isn’t any safer to try and repair on your own.
After original dissatisfaction, the management and technician teams went above and beyond to correct the issue. I never expect perfection, but after voicing my concern, the team came together and made me a 100% happy customer. I would definitely recommend them, as they will not leave you out in the cold. The customer service and professionalism shown by both the managers and technicians was superb. Thanks for taking great care of our family!
Slide the left spring onto the tube and add the cable drum. When your new springs arrive, put the new left spring (the 1 with the end facing up and to the left) on the torsion tube, making sure that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.[9]
