Unlike drier climates, Washington's near-constant moisture works its way into torsion springs, cable ends, and roller bearings year-round. Rust doesn't need a storm to form — it builds slowly through fall and winter, weakening metal fatigue points long before a spring visibly snaps. Homes closer to Puget Sound, including much of Edmonds, Mukilteo, and Everett, tend to see this wear even faster due to higher salt-air humidity.

​

Cold snaps add a second layer of stress: metal contracts in low temperatures, making already-worn springs and cables more likely to fail on the coldest mornings of the year — often right when you need the door most. A yearly tune-up (lubrication, hardware tightening, and a balance check) is the simplest way to catch this wear before it turns into an emergency repair.
