How to Fix a Gap on One Side of Garage Door – A Guide

Dealing with a gap on one side of your garage door can be frustrating. Not only does it compromise the security of your garage, but it can also lead to energy inefficiency and allow pests into your home. Fortunately, fixing this issue is often simpler than it seems. In this guide by Genesis Garage Door, we’ll walk you through the steps to identify and fix a gap on one side of your garage door, ensuring a snug and secure fit.

Griping the Cause of the Gap

Before you can fix the gap, it’s crucial to understand what’s causing it. Several factors can lead to uneven gaps, including:

  • Misaligned Tracks: If your garage door tracks are misaligned, it can cause the door to sit unevenly.
  • Worn Out Weather Stripping: Over time, the weather stripping along the sides of your garage door can wear out, leading to gaps.
  • Spring Issues: If your garage door springs are not correctly tensioned, it can cause the door to close unevenly.

Step-by-Step Guide to Fixing the Gap

  1. Inspect the Tracks: Check the tracks for any signs of misalignment or damage. If you find any, carefully realign or replace the damaged sections.
  2. Adjust the Springs: If the springs are the issue, it may be best to call a professional, as adjusting garage door springs can be dangerous.
  3. Replace the Weather Stripping: If the weather stripping is worn out, remove the old stripping and replace it with new material, ensuring it’s securely attached along the door’s edge.

  • Regular Inspections: Periodically check your garage door tracks, springs, and weather stripping for wear and tear.

  • Professional Servicing: Have your garage door professionally serviced at least once a year to catch any potential issues early.


1. Can I fix a garage door gap myself?

Yes, many garage door gap issues can be addressed with some basic DIY skills. Minor adjustments, such as realigning the tracks or replacing worn-out weather stripping, can be easily done on your own. These tasks require minimal tools and can significantly improve the performance and security of your garage door. Adjusting or repairing garage door springs can be dangerous and should typically be handled by a professional to ensure safety and proper functionality.

2. How often should I check my garage door for gaps?

It’s wise to inspect your garage door for any gaps, wear, or other issues at least twice a year. Regular inspections can help you catch and address minor problems before they escalate into more significant, costly repairs. Seasonal changes can affect your garage door’s alignment and sealing, so checking at the transition between seasons is a good practice.

3. What tools will I need to fix a garage door gap?

To fix a garage door gap, you’ll generally need some basic hand tools. A wrench and a screwdriver are essential for adjusting hardware and securing components. A rubber mallet might be useful for gently tapping parts into place without causing damage.

4. Can a gap on one side of the garage door affect its security?

Yes, a gap on any side of the garage door can compromise its security. Even small gaps can be enough for pests like rodents to enter, and larger gaps may provide enough space for intruders to use tools to gain access. Additionally, gaps can reduce the energy efficiency of your home by allowing air exchange between the garage and the outdoors, which is especially significant if the garage is attached to your house. Ensuring your garage door is properly sealed and secure helps protect your home from both security and environmental elements.

5. What is the best weather stripping material for a garage door?

Vinyl and rubber are among the best materials for weather stripping on garage doors, offering a good balance of durability, flexibility, and cost-effectiveness. Rubber weather stripping, in particular, provides excellent sealing capabilities due to its flexibility, adapting well to slight irregularities in the floor or door surface.
