Self-Repairing Your Garage Door

Step 1 – Measure Your Existing Garage Door

Taking the measurement of your current garage door is important before replacing it with a new one. So, measure the width of the door from the starting point of the structural member. Taking the measurement from the trim piece is not accepted in this case. And also, make sure there is enough headroom for the door to operate smoothly.

Step 2 – Lower the Door

The process of taking down a garage door depends on the build. Some have to be taken down while keeping them hanging from above, and others can be taken apart while they rest on the ground.  Remember to take down the tension springs, then take them down first, keeping the door hanging from the top because there should be no tension while removing the door.

And with that done, keep in mind that there is nothing that supports the load. So, make sure that you have someone to manually take down the door or use clamps at the end of the doorway to make sure there is no impact. A door weighs pretty much around 150 pounds, which can cause significant damage on the door frame if you let go.

Step 3 – Remove the Door Panels

Loosen the brace and take out the pin from the top center brace. Next, take out the nuts and bolts holding the top panel, and it should come off nicely. Repeat this process until all the panels have been removed.

Step 4 – Remove the Door Operator

Unscrew and remove the old operator from the support by undoing the bracket holding it in its place, and cut the wire to stop its operation. Take some assistance to pull the motor down because it’s not a one-man job.

Step 5 – Make the Frame

Remove the old 2″ x 4″ frame of the old door before putting a new one in prior to the door installation.

Step 6 – Check the Door Alignment with the Ground

Properly ensure so that your new door smoothly aligns with the concrete floor of the driveway. Ensure the alignment with a level checker and use a compass to check the distance between the door end on the highest side. Cut off the extra bit using a circular saw and repeat the process until it’s done.

Step 7 – Install Proper Weather Stripping

Apply some weather stripping on the bottom of the door to stop the weather effect.

Step 8 – Attach the angle brackets to make the hinges

Attach the angle brackets all the to the bottom of the door and then work on the hinges.  The angle brackets (marked L and R) and the hinges are marked for correct placement. See a labeled image of the corner bracket and hinges placement for clarity.

Step 9 – Assemble the Tracks and Rollers

Tracks and rollers are easy to assemble once the hinges are set. The track should be set close to the bottom of the wheel, and the brackets should firmly fasten the track to the wall. The track being flexible is easy to attach to the rollers. Fix the track with the new 2″ x 4″ frame.

Step 10 -Mark the Hinges

Use a carpenter’s square marking tool to mark the hinges on the door. Usually, the middle hinge goes 48″ inside from the side, and the last hinge goes 1 – ¾” from the edge.

Step 11 – Assemble the Door Panels

At this point, it’s time to bring inside all your tools because the door assembly has to happen from the inside. Make sure to follow the manufacturer’s instructions very carefully to assemble the door because the springs on them are very rigid.

Step 12 – Attach the Tracks

Attach the tracks once you are sure that the rollers won’t get stuck or bump in the tracks. Make sure to attach the horizontal and the vertical tracks seamlessly so that the rollers do not bump while operating.

Step 13 – Install the End Bearing

The end bearing is one of the simplest things to install, yet it forms the base on which the tension rod slides through and spins to operate. Attach a hex head in the bottom, and a carriage bolt up on the top.

Step 14 – Attach the Hinges

Its time to attach the remaining panels using the hinges and the screws. These screws for attacking the center bracket is harder and different than the rest because it needs to last longer.

Step 15 -Assemble the Cable Spring

The cable spring goes hand-in-hand with the bottom door panel. You can use professional help if you find this one difficult to do by yourself.

Step 16 – Install the Support for the Operator

Firstly, install the operator bracket that holds the operator to ensure the giant motor is secure on top. After that, attach the bracket that supports the header support block, rail of the operator, and finally mount the motor.

Step 17 – Install the Trim and Paint

Get rid of the old caulk using a paint scraper and buy a new vinyl trim. Finally, paint the door for a finished look.
