Replacing a Broken Garage Door Window
A broken garage door window can cause injury, lawsuits, and could be a security problem. The door is the likely the largest movable mechanism in a home and can weigh up to 400 pounds. Unlike a house window, the garage door window is part of this large moving structure. It is almost certain to drop broken glass. Given Houston’s weather, a broken window left unrepaired can result in water damage. It is also a clear invitation to insects and rodents. To replace a window you will need:
- 1. A pair of protective gloves.
- 2. A rubber mallet.
- 3. A tape measure.
- 4. A ladder.
- 5. A helper as this is a two person job.
This is a six-step process:
1. Remove power. The first step is to remove power if the door has an opener. Unplug the power cord from the overhead electrical outlet.
- 2. Remove the frame. The next step is to remove the screws which secure the window frame to the door in insulated doors. For non-insulated doors, remove the retainer snaps from the frame. Have the helper hold the window frame to the door from the outside during fastener/screw removal. Remove the screws/retainers snaps from the top of the door first, and then proceed to the sides, and then the bottom.
- 3. Remove the broken glass. Carefully clear any remaining glass out of the frame, starting at the top. Measure the inside height and width of the frame. Subtract 1/16 inch from each dimension and purchase a single strength plane of glass.
- 4. Insert the frame. Insert the frame into the garage door from the outside. Ask your helper to hold the frame flush against the door.
- 5. Replace the glass. Place the glass into the window frame and secure the inner retainers with the retaining screws if your window frame uses screws. If snaps are used, press as far in by hand as possible, then tap gently in with a rubber mallet.
- 6. Repower. Lastly, plug the power cord into the overhead outlet if the door is controlled.
