Directions for Installing a Garage Door

    Bottom Panel

    • The bottom piece of the door should have weatherstripping on the bottom and holes for hinges on the top. Hold this panel in place so it can't move. Nail it partially to the door jamb; use nails long enough to drive into both the panel and the jamb at an angle and still have plenty of room to remove them at the end. By now, you also need to have assembled the vertical tracks--the ones that run alongside the door--as per the manufacturer's instructions. You might as well assemble the curved and horizontal tracks now also. Connect the rollers for the bottom panel and slide each vertical track down onto the rollers on each side, connecting the panel to the tracks, If there are any brackets that connect the tracks to the jamb at the bottom of the door, you need to install those, too.

    Other Panels

    • The hinges for each panel are screwed on; using a power drill with the right screwdriver bit will make it easier. Attach the hinges to the top of the bottom panel. Now take the next door panel with its rollers connected and slide it into the tracks; you'll likely need a second person to hold and/or bend the tracks so you can insert the rollers. Once the rollers are within the tracks, fasten the panel to the bottom panel by connecting the bottom hinges to the new panel's bottom edge. Repeat this for every door panel. As you do this, you should use levelers to make sure the door is level and the tracks are plumb against the jamb.

    Vertical Tracks

    • Once the full door is installed, fasten the vertical tracks to the wall at the top plates; their lag screws need to penetrate the door frame within the wall to support the force the door will exert. When fastening the track's jamb brackets into the wall, don't drive their lag screws all the way in yet, because you might need to adjust the tracks later.

    Curved/Horizontal Tracks

    • Connect the curved tracks to the top of the vertical tracks with their screws or bolts, then attach the horizontal tracks to the curved ones. The horizontal tracks run parallel to the ceiling. Before the ceiling hangers installed, the horizontal tracks might need to be balanced on a ladder. You may also need to cut the hanger's length so it properly fits between the track and the ceiling. When screwing the track in place, make sure to screw it into a ceiling joist.

    Torque Tube

    • If the garage door comes with a torque tube, it's installed above the garage door and connects to the tracks with brackets that attach to the curved tracks. Because the tube and springs contain a lot of tension, you must follow the manufacturer's exact instructions and may be better off leaving this part to a professional. If you're going to install a garage-door opener, wait until you install that before tackling the torque tube.
