Broken Springs or Cables

Garage doors consist of various components, including springs and cables, which play a crucial role in their smooth operation. Springs are especially important as they counterbalance the weight of the garage door, making it easier to open and close. There are typically two types of springs used in garage doors: extension springs and torsion springs.

If the springs or cables in a garage door fail, it can have a significant impact on the door’s closure. When springs break, they no longer provide the necessary counterbalance, making the door extremely heavy to handle. This makes it difficult for individuals to manually close the door, and it can even pose a safety hazard as the door may suddenly slam shut. Additionally, broken springs can cause the garage door opener to work harder, potentially leading to malfunctions or complete failure of the opener itself. Similarly, if the cables in a garage door become damaged or break, the door’s closure can be compromised. Cables are responsible for lifting and lowering the door evenly, so any damage can result in an uneven closure or even prevent the door from closing completely. This not only compromises the security of the garage but also exposes it to harsh weather conditions and potential theft.
