If you want to do the repair yourself, get several phone estimates first, because rates vary widely among service companies. Most garage doors are heavy (200 to 300 lbs.), so call in three strong friends to help you lift the door and hold it open while you lock it in the full raised position with a locking pliers. Then move your vehicles and have your friends help you lower the door.
Check your garage door rollers to see if they have come off their tracks. If no damage has been done, a tech should be able to easily place them back on. If the track has become bent, however, it must be repaired and possibly (depending on the amount of damage) replaced. Don’t operate your door if it's off track or your track is bent. Your door could become seriously damaged. 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. http://www.youtube.com/embed/Z_eZc-kh40c
To install a single new garage door it should cost between $500 and $800. They demonstrate that the average homeowner can usually tackle such a project in a nine hour time span and a professional will be able to complete it in roughly five hours. Should it be a DIY project? Not really, most housing experts point out that it is a two-person job, requires advanced carpentry skills, and even knowledge of household electronic systems.
A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.
One of the large springs on our garage door broke the day before Thanksgiving, trapping our van inside the garage. We have a daughter in a wheelchair and had lots of errands to run before Thanksgiving, so we really needed our van. We called Overhead Garage Door and they told us approximately when they would arrive. They not only replaced the broken spring, they replaced the other spring, all of the rollers and most of the hinges. They also replaced several rollers and hinges on the second garage door. The technician, Micah, and his brother could not have been nicer. The garage doors have never worked as well or been this quiet. I highly recommend Overhead Garage Door to anyone in need of new garage doors, or repairs to existing doors. A first class business.
Often companies will show different types of springs like oil dipped, galvanized or powder coated and try to convince you that one is longer life than the other and that is why it is going to cost this much instead of that much. Galvanized and Powder coated are great for coastal areas as a rust preventative but do not change the cycle life and do not cost but a few dollars more.
In most cases, only one spring breaks or wears out at a time, and you can get away with replacing just the failed spring. But this is a little like replacing old car tires one at a time. You'll get the best performance if all the springs are new and have the same strength. Extension springs are replaced individually, making it more tempting to replace just one. With torsion springs, you have to disassemble everything to replace either spring, so it makes sense to swap out both springs during the repair.
