Note: Before installing a new garage door, seek the advice of a professional. Doors made for most homes today use torsion springs (figure A), which are tightly would and can be dangerous — all the more reason to hire or consult a professional installer.
You’ll need an extra pair of hands to help take down the old door.
To begin installing the new door, slip the weather stripping into the channel at the bottom of the door, tucking in any excess to ensure a good seal (figure B).
Add vinyl trim around the frame to help with the seal and to give a finished look.
Set the first panel in the opening. Hold the panel in place and drive temporary nails at an angle into the door framing — but not through the door. Bend the nails over the ends of the panels to secure them.
Make sure the panel is level then continue stacking the remaining panels.
Install the hinges along the edges and middle of the door. Insert the roller shafts into the hinges and install any necessary brackets.
Place the tracks around the door. The mounting brackets should sit against the wood frame.
Assemble the curved J-shaped tracks and mount (figure C). Use a level to get the track even.
The rear track hangers carry the full weight of the garage door, so attach these securely to a rafter or joist. You’ll want to add barring brackets to the end and middle, which will hold the top roller.
Insert the outside brackets.
Finish by running a lift cable to the drum that connects the spring and doors. Test the door to make sure it closes gently on the floor. If the door lands too hard, simply increase the spring tension. Decrease the spring tension if the door doesn’t land hard enough.
Having a garage door is something you may take for granted but having one that works well can make life easier.
