Bi folding doors are a fantastic way to open up your home, connecting indoor and outdoor spaces in a stylish, functional way. However, even the best doors won’t perform well if they’re not installed correctly. From incorrect measurements to poor alignment, there are several common mistakes that can impact the doors’ performance, longevity, and overall functionality. Let’s go over some of the most frequent pitfalls to avoid to ensure your folding work smoothly & last for years to come.

1. Incorrect Measurements
One of the common mistakes is inaccurate measurements. If your door opening isn’t measured precisely, it can result in doors that don’t fit properly, leading to gaps or problems with operation.
What You Can Do:
- Measure the top, middle, and bottom of the door frame to account for any unevenness in the walls or floors.
- Double-check both the height and width before you order your doors.
- Consider having a professional handle the measurements to make sure everything’s spot-on.
Accurate measurements are the foundation of a successful installation and can help avoid costly adjustments later on.
2. Choosing the Wrong Material
Picking the wrong material for your bi-folding door panels or frame is another common issue. Different materials come with their own set of pros & cons, so it’s important to choose wisely.
Here’s a quick guide:
- Aluminum is lightweight, durable, and low-maintenance, making it a great choice for most homes.
- Timber gives a classic, natural look, but it requires regular maintenance to prevent issues like warping or decay.
- UPVC is budget-friendly and resistant to moisture, but it might not be the best choice for large door spans.
Choosing the right material will ensure your bi-folding doors stay functional and look great for years to come.
3. Ignoring the Track System
The track system is must for smooth operation. If the tracks are installed improperly or are of poor quality, your doors might stick, jam, or just not slide as smoothly as they should.
What to Keep in Mind:
- Make sure the track is level and securely fastened.
- Use high-quality rollers and tracks that are compatible with your door panels.
- Clean the tracks regularly to prevent dirt & debris from building up, which can cause problems down the road.
By paying attention to the track system, you’ll ensure your doors operate smoothly and last longer.
4. Poor Alignment of Panels
If the panels aren’t aligned correctly, you could end up with gaps, poor seals, or doors that don’t close properly. Misalignment can even impact the doors’ security and aesthetic appeal.
How to Avoid This:
- Use a level and spacer blocks to check the alignment as you go.
- Frequently check the alignment of each panel during installation.
- Adjust the hinges and rollers as needed according to the manufacturer’s instructions.
Proper alignment leads to better energy efficiency, smoother operation, and improved security.

Many people overlook the importance of weatherproofing, but if your bi-folding doors aren’t sealed properly, you might end up with drafts, water leaks, or dust getting inside. Over time, this can damage your interiors and affect your comfort.
What to Do:
- Install high-quality gaskets or seals around the edges of the doors.
- Consider adding weatherstripping for external doors exposed to the elements.
- Regularly inspect the seals to ensure they’re intact and replace them when necessary.
Good weatherproofing helps keep your home comfortable and protects your doors and interior from the elements.

While DIY projects can be fun, installing bi-folding doors isn’t something most people can do without the right expertise. Attempting it yourself can lead to all kinds of issues, from uneven panels to faulty tracks.

Simple Maintenance Tips:
- Clean glass panels and frames with appropriate, non-abrasive cleaners.
