Your home's garage door goes up and down thousands of times per year - that's a lot of work for one door! That's why it's important to keep your garage door in proper working order. Garage doors provide convenience and security, but if they become damaged garage doors can become noisy, a security risk and a safety risk. Garage doors get their lift from high-tension springs mounted on either side just above the top of the garage door frame. Extension springs are used on single garage doors and tension springs on double garage doors. Extension springs extend and contract and are only able to lift limited weights such as the weight of a single garage door. Tension springs are stronger because they are wound up like coils. Tension springs are under extreme pressure and can lift double garage doors.
