How to Replace the Bottom Panel of a Garage Door?

January 19, 2024

Modern garage doors are designed in sections, with each panel able to fold when the door is opened. If one of these panels is damaged, it can affect the entire mechanism, so your door doesn’t open and shut properly. 

Bottom panels, in particular, are prone to damage because they are the closest to the ground. With that in mind, the garage door specialists team at Active Door is here with this quick guide on how to replace the bottom panel of a garage door. 

Common Reasons for Bottom Panel Damage

The bottom section of your garage door can become damaged for several reasons, most commonly overuse/age, bad weather, and impacts. Fortunately, you can often get away with just replacing the damaged panel instead of the entire door. 

However, you shouldn’t wait to fix the damage, as a broken panel can pressure other parts of the door. Specifically, door tracks might not properly support broken panels so the additional weight can pull the rest of the door off the tracks. A broken door might also leave gaps, creating a security risk. 

Changing a Garage Door Bottom Panel: Step-By-Step Guide 

This section will cover how to replace the bottom panel of a garage door. Before starting the job, you’ll need a few tools to make things easier:

  • Vice grips
  • Hoists
  • Measuring tape
  • Impact wrench
  • Gloves
  • Replacement panel

First, make sure you unplug the power cord to your garage door and detach the garage door opener from the door. Next, place one hoist near the top of the door on the track and the other at the second-to-last hinge from the bottom. You can then slightly lift the door off the ground to isolate and remove the damaged bottom panel.

From there, place the new panel into position, use the vices to secure it to the track, and attach the hinges and flange nuts and bolts on both sides. Secure the cable, attach it to the bottom bracket on the new panel, then slide the rollers onto the track. Once the bottom panel is secure on the track, lower the hoists and connect the hinges of the upper part of the door to the new bottom panel. Now, you can remove the hoists, turn the opener back on, and test the door to see if it opens and shuts properly. 

The new garage door section can be fairly heavy, so we recommend getting a second person to make sure the panel is stable when you are attaching it. Also, you should always wear gloves when dealing with cables and hinges, as they can cut or pinch your fingers.
