Removing a sectional garage door is a job best left to a specialist, but if you are mechanically inclined and enjoy a challenge, you can save some money. The sectional garage door uses a system of hinges, tracks, rollers, pulleys, and springs to move up and down with or without a power opener. They might be made of wood, aluminum, steel, and full-view windows. Sectional garage doors are hinged to roll up into overhead space. Tracks on both sides of the door are secured with angle iron or struts.
Step 1: Ensure Safety
Plan the project in advance as in how would you do what, as removing a sectional garage door can be a dangerous job. The door is too heavy for one person to handle, although it is removed in sections. Try to have a second person available for the job. Either way, safety is of utmost importance. Keep several 2- to 4-foot pieces of wood nearby for bracing the door when necessary. Wear safety glasses and work gloves when handling the springs and other metal parts of the mechanism. Unplug the power garage opener if one is attached to the door. Keep the floor beneath the door where you will be working free from debris.
Step 2: Remove the Springs
The door is leveraged by a series of cables and springs to keep it gliding smoothly along the C-track channel in which it fits. Some doors use both torsion springs across the front and tension springs on each side of the door. Only the tension springs need to be removed. Your first job is to release the tension from these springs. Raise the door to the very top of the channel, releasing it from the power opener mechanism to raise it completely. Place C-clamps on each side of the track to hold the door in position. Loosen the tension springs and remove the attached cables from the lower door panel.
Step 3: Unhook the Hinges
After removing the springs and cables, lower the garage door to the floor. Each panel of the door is connected with a group of hinges. Using the drill/driver and sockets or screwdriver if necessary, remove the screws from all hinges. This will leave the door hanging as individual panels. Raise the second panel slightly away from the first and secure it with C-clamps. This is to keep it from falling when the first panel is removed.
Step 4: Removing the Rollers
Remove the rollers from each side of the first panel. It should slip from the track to be taken from the opening. Lower the next section to the floor and use the C-clamp again to separate it from the others. Loosen the rollers on each side so this panel can be removed from the garage opening. You need to repeat the steps for the remaining panel until the sectional garage door has been removed completely.
Once you are done with the doors, your project is finished.
