How many turns on a garage door spring chart?
A rule of thumb with springs is that four quarter turns equals a full revolution and the spring needs to be tightened a full revolution for every foot of door height (e.g. 7-1/2 foot door = 7 revolutions +2 (30 quarter turns).
What do garage door spring numbers mean?
When you look at the stationary or winding cone, you may spot a number such as 2.0 or 1.75. If you see the former, this means that the spring has a 2-inch diameter. That measurement is the spring’s diameter. The other important measurement of your garage spring is its overall length.
What is the average life of a garage door spring?
The average garage door spring, if correctly installed, should last about 10,000 cycles of opening and closing. If you only go in and out of your garage once a day, that means you should expect a broken garage door spring around 14 years after the spring is first installed.
What is the average cost to replace a garage door spring?
$150 to $350

Which way do you turn a garage door spring?
This is pretty easy to determine. Basically, door springs can either wind to the left or to the right. Right-hand winding springs wind in a clockwise manner with the end wire on the right, while left-hand winding springs go anticlockwise with their end wire on the left.
Do garage door springs wear out?
There is no hard and fast rule for how long torsion springs will last. But if you have a very heavy garage door, the springs could wear out after only four years. You can check the springs themselves for signs that they are weakening. If you notice gaps between the coils of the springs, they may need replacement.
Should you replace both garage door springs at the same time?
When replacing tension springs, it is recommended that both springs be replaced and matched because the older, unbroken spring will have lost some of its tension from years of use. Replacing both springs helps to balance the door so that it opens smoothly with equal force being applied to each side of the door.
Does garage door spring size matter?
Springs That Are Too Small Can Make the Opener Less Effective. If the spring for the door is small, it can make the door too heavy. When someone tries to raise the door, it will fall back down instead of continuing to lift. A user unaware of the garage door issue could get hurt by the door falling shut.
