If you are thinking of buying a new garage door spring – or you are forced to because your one broke – then there are two main types of spring that you need to be aware of. Both are high tension and potentially dangerous, so don’t try and fit them if you don’t know what you are doing otherwise you could put yourself in danger.
The first type of spring you can buy is the torsion spring. These are wound up above the door on a rod, with one on each side. You need to inspect them both at the same time because if one isnt working correctly then it will put extra strain on the other causing it to break faster.
Torsion springs are usually used when you want an electric door as they can lift most of the weight of the door by themselves. You need to be careful with torsion springs as they are under such high pressure they could do you serious harm if they release unexpectedly.
Extension springs are more easy and less dangerous to repair by yourself. They usually go along the top and sides of the door and extend to lift, hence their name! You still need to be careful of the springs though because if the door is open they will be under high pressure.
If you aren’t completely sure how to repair your garage door springs or replace them with new ones then it always pays to get a professional in to do it. It will save you money in the long run and maybe even an injury.
Another good reason for hiring a professional is that they will make sure the springs are properly aligned so that they don’t break. If you want to get the maximum out of your springs then it is vital you get them fitted correctly otherwise they wont last anywhere near as long as they should or as long as you expect them to.
