Torsion Spring Extortion
Garage door springs don't last forever and it's usually a DIY job to replace them. But do you have torsion springs or extension springs on your doors?
Extension springs are perfect for DIYers because you can buy them at your local home centers and they are trivial to replace.
Torsion springs are a little more work to replace, but they are very hard to fix QUICKLY because you might have a hard time finding them locally.
