Springs are one of the primary components in all garage door systems. Torsion springs are usually mounted horizontally over the door opening. As the door closes, cables add tension to the springs and as the door opens that tension is released. The opening of the door causes the springs to unwind in conjunction with the weight coming off the door. This achieves a natural buoyancy. However, as the door moves up and down over time and the cycle count rises, the steel in the torsion springs will grow weak and will no longer be able to create energy or lift your garage door.
Delivered on time, with the products described: springs, winding bats, & plastic bushing. Quick install, but apparently I measured wrong, so these total length I bought was larger (which is good as there is less stress on the spring). However this did mean that I needed more than the generic rule of 30 1/4-turns of preload. I wound up with 38 1/4-turns per side for the door to balance when open 3' (per familyhandyman.com recommendations). Would definitely do it again.
As a first time homeowner, Home advisors is an invaluable tool! There is a steep learning curve that comes with buying a house!!!! Being able to have access to unbiased information is great! It really helps to have a basic idea of what costs are, and all the different things that go into each project. who knew that there was so much to consider when looking to replace garage doors!!!!
Torsion springs do not last forever, regardless of what some companies claim. “Lifetime” springs do not exist – all springs have a lifespan. Most builders typically install the lowest costing door available and with that generally comes lower cycle springs. A torsion spring’s life is determined by the number of cycles the spring is rated to last. Whenever the door goes up and down is what is referred to as a “cycle.” The springs that builders install can last as little as 7,500 cycles which means the average homeowner could get 3-5 years of life. http://y2u.be/Z_eZc-kh40c
