How do I know what size garage door spring I need?
Basically, you run a tape measure along the length of a spring, and take down the number of inches. Therefore, if your tape measure indicates that a torsion spring is 36 inches from one end to the other, that’s a 36-inch — or three foot — torsion spring.
Can I use a different size garage door spring?
When you add everything up, you have the exact weight once done; you can then use two different size springs if it yields optimal balance. If you are a homeowner and the technician used two different size springs, don’t be alarmed. What matters is that the garage door is balanced.
What type of garage door spring is best?
Coated torsion springs are best. Torsion springs are safer than extension springs and often last twice as long. Coating a torsion spring makes it last even longer than a regular torsion spring.
What weight garage door springs do I need?
This is determined by the pitch with which the springs are wound. On sectional garage door springs, this normally is 15 percent. For example, a 100-pound pull spring requires 15 pounds of weight to separate the coils; when a door is open, the two springs will support 15 pounds of door weight without any stretch.
How much is a spring for a garage door?
Replacing garage door springs costs $150 to $350 on average. The springs alone typically run $30 to $75 each but you may find them as low as $15 a piece and up to $100 each. Commercial grade springs can run $300 or more.
Can I use a heavier garage door spring?
If your garage door springs have lasted less than five years, or if you plan to live where you are for many years, you may want to try the extra long life torsion springs. By using larger springs, you can, in most cases, quadruple your spring life while only doubling the cost of the springs.
How many turns on a 7ft garage door spring?
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).
Are torsion springs better than extension springs?
Torsion springs tend to be stronger and more durable than extension springs. And though they are more expensive, they last longer, between 15,000 and 20,000 cycles as opposed to 10,000 cycles with extension springs. They also offer greater balance and show more control when moving, not jerking as the door moves.
Do you need garage door springs?
These springs are essential for opening and closing your garage smoothly, especially if you have two. This means that you shouldn’t use your garage door opener without any springs since residential openers don’t typically have much horsepower.
Can you over tighten garage door springs?
1) Secure the door in place by putting a C-clamp on the garage door track above the bottom-most door roller. As you adjust the spring more tightly, there is the chance that the door may begin to rise if you overtighten it… a dangerous possibility!
How often should you change garage door springs?
A standard garage door spring should last between seven and 12 years before the stress it experiences through usage requires it to be replaced. You can reduce the risk of garage door spring damage by applying a small amount of spray lubricant to the garage door’s components twice a year.
