Car garages can be compared to the horse stables of yesteryear. But the comparison ends right there, because the present day garages are automated, and they are fitted with contemporary security devices and door openers. The doors will be easier to open and close thanks to the involvement of the springs. These springs will break down over time, so it's important that they be replaced occasionally.
All garage doors fitted with a spring will be easy to open thanks to the application of the spring torsion principle. These springs are fitted in pairs and they are fitted on both sides of the door on the top portion. There are two types of garage door springs. Extension springs and torsion springs are the two main types. The use of torsion springs is much more common since they can last upwards of seven years.
With time and continuous operation, the garage door spring gets stretched and at one time it wears out in front of the stress. When this happens, it is a standard practice to replace the pair together. If you only replace one spring, then the other may break down in the future and need replacing too. You can think of extension springs as stretching mechanisms. You can expect these springs to last about seven years as well. These springs will set you back about $50. Your particular door may require a certain type of spring, so you will need to see what model you have.
The cost of replacing springs depends on two main factors. The cost of labor as well as the cost of the materials will play a role. Since the springs are under so much tension, replacement can be a very dangerous job. For this reason it is always a better option to allow only a professional to handle the replacement task.
It will take a few hours to get the job done. With all of the costs figured together, you can expect to pay anywhere between $150 and $300. If the company tries to charge you more than this, you should absolutely see why. The professional may try to repair other areas that don't really need it in order to charge you more money. Don't let them make the other repairs without your permission, as you should only try to get the necessary repairs done.
