The most traditional and common type of garage door is a folding garage door. These doors are typically assembled with hinges in between each panel to allow for folding.
Step 1: Seal The First Panel With Weather Stripping
Assembling and installing a folding garage door is fairly simple and with the right tools, will not require much time.
To begin assembling and installing your folding garage door you will need to start by sealing the bottom of your first panel (the one that will be on the bottom) with a layer of weather stripping.
After sealing the bottom, position it into the entryway of your garage and hammer nails into the jambs on an angle to temporarily secure the door in place.
Attach the hinges to the top of the first garage door panel.Step 2: Put Together The Tracks
The next thing that you will need to do is to assemble the tracks that came with your garage door. You will have to assemble curved, vertical and horizontal tracks. Consult your manual for correct assembly instructions.
After you have your tracks assembled, attach the rollers and the brackets to the garage door. Place the vertical tracks on each of the rollers for the door. Fasten both of the vertical track’s top plates to the garage wall. Ensure that the lag screws are firmly secured to the framing material. These screws support the extreme force of the garage door opening and closing.Step 3: Attach The Hinges and Mount The Brackets
Using a power drill, or if you don’t have one, a nut driver, attach the hinges to all three sections of the garage door. Use a level to make sure that the tracks are level. Once you ensure that the tracks are level, secure the upper discs to the wall.
Once you have the upper discs of the vertical track secured to the wall, you will then need to mount the jamb brackets to the tracks as well as the framing material using the lag screws. When attaching the jamb brackets, make sure they are going into a sound and secure position.
Use you level and make sure that the horizontal track is level. Once you check it, you will need to trim back the hanger that is located on the back side of the track to the proper length. Once it is trimmed, attach the hanger to a permanent object. One method is to attach it to the garage wall or ceiling.
Once you have that done, fasten the track to the hanger.
Step 4: Hang The Door
Once you have assembled, secured and leveled the tracks you are now ready to hang the door itself. Position the door in the permanent location. This job is typically better done by multiple people.
Remove the nails that you used to secure the first panel in place at the beginning of your project.
Once you have the door in place, double check the track alignment and secure the fasteners. Make any needed adjustments at this time.
If you are using an automatic door opener you will not need to install a torque tube. If you are planning on using this door without an opener, consult the manufacturers instructions and install the torque tube now.
Once you have the door secured, test it to make sure that it goes up and down easily. If you find that your door will not stay up, use your ladder and adjust the tension springs at the top of the door.
