Nearly every company that sells garage doors offers full garage door service, including delivery, removal of your old door, and installation.
Because garage doors are large, heavy, and mildly complicated, most people who buy them take advantage of these services. But, if you’re pretty adept at DIY tasks, you can save some money and enjoy the satisfaction of doing the job of installing a sectional garage door yourself. (Sectional garage doors travel up and down on rollers that ride along tracks at each side of the garage doorway.)
The garage door shown is equipped with a torsion spring system, which is much safer to adjust than the typical torsion-spring model.
You should not attempt to adjust or remove a garage door that has a standard torsion-spring mechanism because these are under extreme tension, which makes them dangerous. Call a professional garage door installer instead.
The instructions that follow will guide you through the general principles of sectional garage door installation. Be sure to follow all of the manufacturer’s instructions implicitly.
