The technician will unwind and remove all of the springs on your door and will replace them and as such, be prepared to spend up to $400 and even more. There are also some wooden garage doors that have two springs, yet they are extremely big and could cost as much as $400 to repair.
Introduction. Few things in nature can compare to the destructive force of a hurricane. Called the greatest storm on Earth, a hurricane is capable of annihilating coastal areas with sustained winds of 155 miles per hour or higher, intense areas of rainfall, and a storm surge.
In high category hurricanes (e.g. category 3 or higher), wind-borne debris damage occurs essentially in parallel with the damage due to differential pressures. Wind speed tends to decrease significantly within 12 hours after landfall (for more detail see Interaction between a Hurricane and Land).
