Noticing gaps around your garage door? Whether it’s light coming through the sides or cold air under the door, these issues are more than cosmetic. Left unaddressed, they can lead to energy loss, water intrusion, pests, and long-term damage.
At ProLift Garage Doors of Spartanburg, we regularly diagnose and correct these problems. Below are the most common causes of garage door gaps and how to address them.
1. Worn or Damaged Weatherstripping
Your first line of defense is the garage door weatherstripping. Over time, it can crack, flatten, or pull away.
Common signs:
- Visible garage door side gap
- Brittle or missing vinyl
- Light coming in around edges
Solution:
- Replace side and top seals
- Ensure tight contact with the door
This is one of the most effective ways to seal gaps in garage door openings.
2. Failing Bottom Seal
The garage door bottom seal closes the gap between the door and the floor. If it’s worn or damaged, you’ll see daylight underneath.
Issues include:
- Flattened rubber
- Torn seal
- Uneven contact with the floor
Fix:
- Replace the bottom seal
- Consider adding a garage door threshold for extra protection
3. Uneven Floors or Driveways
Even a perfectly functioning door can have gaps if the concrete is uneven.
Symptoms:
- One side touches the ground while the other doesn’t
- Water entering under the door
Solution:
- Install a threshold seal
- Adjust the door where possible
4. Garage Door Alignment Problems
If your door is not sitting square in the opening, you may notice a garage door top gap or uneven spacing along the sides.
Causes:
- Shifted tracks
- Loose hardware
- Structural settling
Fix:
- Professional adjusting garage door tracks
- Realignment of the door system
These types of garage door alignment problems should be handled carefully to avoid further damage.
5. Garage Door Fitment Issues
Sometimes the door itself is not the correct size or was not installed properly.
Indicators:
- Persistent garage door frame gaps
- Uneven spacing all the way around
- New door with immediate issues
Solution:
- Evaluate for garage door fitment issues
- Replace or modify door components as needed
6. Insulation and Panel Issues
Damaged or poorly insulated doors can contribute to garage door insulation issues and allow air to pass through.
Look for:
- Warped panels
- Cracks or separation
- Increased garage door air leaks
How to Fix and Prevent Garage Door Gaps
Addressing these issues early helps prevent drafts in garage spaces and improves energy efficiency.
Recommended Steps:
- Replace worn seals and weatherstripping
- Install a threshold for uneven floors
- Check alignment and track condition
- Inspect door panels and insulation
These are all part of effective garage door sealing solutions and long-term weatherproofing garage door performance.
