Why Glass Doors Fail: The 5 Most Common Mistakes We See

At Open Entrances, we’ve worked with countless clients who came to us after their original glass door installations didn’t live up to expectations. Whether it’s premature wear, performance issues, or safety concerns, many of these failures trace back to a handful of avoidable mistakes.

Here are the five most common reasons glass doors fail and how to avoid them when planning your next installation.

1. Poor Alignment

A glass door that’s not aligned properly from the outset is guaranteed to cause problems. Misaligned doors can scrape against floors, fail to close correctly, and place undue stress on hardware and hinges, leading to faster wear and tear.

What to do instead
Work with a specialist installer who understands the specific tolerances required for glass systems. Precision during installation is everything. Regular maintenance checks can also keep alignment in check over time.

2. Incorrect Glass Selection

All glass is not created equal. Choosing the wrong type, such as annealed glass instead of toughened or laminated glass, can compromise safety and durability. We’ve seen doors fail due to cracking under pressure or failing to meet required building standards.

What to do instead
Always assess the environment, usage level, and legal requirements before selecting your glass. At Open Entrances, we’ll guide you through the right options, whether it's for a high-traffic retail space or a statement entrance for a corporate HQ.

3. Seal Failure

Glass doors are more than just panels and hinges. Seals are crucial to performance. When seals fail, it can lead to water ingress, draughts, energy inefficiency, and even structural movement.

What to do instead
Use high-quality sealants rated for long-term performance and ensure proper application. Checking for degradation during routine inspections can help you catch minor issues before they escalate.

4. Incompatible Hardware

Not all hardware is suitable for glass doors. Using ill-fitting or low-grade components, especially closers, handles, and floor springs, can undermine even the best glazing work.

What to do instead
Specify hardware that’s purpose-built for glass. Look for load-tested, durable fittings and match them to the weight and function of the door. Our team helps clients get this right every time.

5. Lack of Planning for Movement

Buildings move, especially larger commercial properties. Failing to account for thermal expansion, settlement, or structural sway can put stress on glass doors and their frames, often leading to cracking or mechanical failure.

What to do instead
Build flexibility into the design. Expansion joints, floating frames, and careful planning of door positioning can allow for natural movement without putting your doors at risk.

Prevention Starts with Expertise
The good news is that every one of these issues is preventable with the right planning, materials, and installation partner. At Open Entrances, we combine deep technical knowledge with hands-on experience to make sure your glass entrance performs flawlessly from day one.
