Garage door covers are an easy and creative way to decorate your home for holidays and events. But sometimes, after installation, you may notice small issues like wrinkles, gaps, or an uneven fit. These problems are usually minor and can be fixed in just a few minutes with the right approach.
This troubleshooting guide explains how to identify and correct common issues such as poor fit, wrinkling, and loose edges to help your garage door cover look smooth and well-aligned.
1. Check Your Door Size and Alignment

One of the most common reasons a cover doesn’t fit correctly is improper sizing. Covers are designed to fit snugly, often being slightly smaller than the garage door’s measurements to avoid sagging.
Before installation, measure your door’s width and height inside the frame, excluding trim and weather stripping. This ensures that the cover you’re using matches your door’s actual panel area.
If the cover seems off-center, remove it and start from the top center, working your way outward and downward for even placement. Keeping the door closed during this process helps maintain alignment.
2. Smooth Out Wrinkles and Air Pockets

Wrinkles and air pockets are often caused by uneven tension or residual fold lines from packaging.
How to fix it:
- Lay the cover flat for 15–20 minutes before installation to let the fabric relax.
- Clean the top panel of your garage door before applying the Velcro strip to ensure a firm hold.
- As you secure the cover with Velcro, smooth outward with your hands or a soft cloth to push out trapped air.
- Check for even tension on both sides. If one side feels looser, detach and realign slightly until the surface appears even.
Avoid using direct heat to remove wrinkles, as this can damage the material. Instead, allow sunlight and gentle tension to naturally smooth it out.
3. Eliminate Gaps Along the Edges
Small gaps near corners or edges can occur if the cover is not fully stretched or if bungee bands are uneven.
How to fix it:
- Always secure the top edge first, pressing it firmly to the door’s surface.
- Attach the bottom bands or hooks evenly on both sides. Adjust them until there’s consistent tension when the door moves.
- If the weather is very hot or cold, install during moderate conditions for the best material flexibility.
- For minor side gaps, you can use additional Velcro strips or adjust the cover’s position slightly to ensure it sits closer to the frame.
4. Reinstall if Needed
If wrinkles or misalignment persist after adjustments, it may help to start fresh. Remove the cover and reinstall following a top-down sequence:
- Position and secure the top edge first.
- Smooth the cover downward and outward while pressing firmly.
- Attach bottom straps or elastic bands last, ensuring consistent tension.
- Open and close the door to confirm that the cover moves smoothly without stretching or lifting.
This method helps the material sit flat and prevents wrinkles from reappearing later.
5. Preventing Future Issues
A few simple maintenance habits can keep your cover in great shape for future use:
- Store the cover rolled, not folded, to avoid deep creases.
- Clean and dry it before storage to prevent dirt buildup.
- Recheck strap or clip tension periodically if the cover is displayed for an extended time.
- Install only on a clean, dry surface to maintain Velcro strength.
Following these steps will make your next installation quicker and ensure a smooth, wrinkle-free look every time.
