Common Issues with AluK Bifold Doors

 

Even high-quality AluK doors can experience issues over time. Some problems result from everyday use, while others are caused by poor installation, which can create long-term operational problems.

​

Common issues include:

​

• Dropped or Sagging Panels – Misaligned tracks or worn rollers can cause panels to drop. Poor installation can leave panels off-level, putting extra stress on hinges and locks.

• Stiff or Sticky Operation – Debris, roller wear, and temperature changes can make doors difficult to operate. Installation misalignment can worsen these problems.

• Worn Rollers or Wheels – Leads to uneven folding or dragging panels, especially when initial installation leaves uneven weight distribution.

• Hinge & Pivot Problems – Misalignment from installation or settling can cause jerky movement and increased stress on hardware.

• Track Misalignment – Tracks installed out of level or square can lead to rubbing, dragging, or uneven folding.

• Locking Mechanism Issues – Misaligned multi-point locks can fail to engage properly, often worsened by off-level panels.

• ​

Toe and Heel Misalignment

 

A long-term issue from poor installation is toe and heel misalignment, where the top (toe) and bottom (heel) of the door panel do not sit correctly within the frame.

​

Signs:

​

• Panels appear tilted when folded or closed

• One side drags while operating

• Increased stress on rollers, hinges, and locks

​

Causes:

​

• Panels not level during installation

• Frames not properly squared

• Building settling over time

​

How Pro-Lock Corrects Toe and Heel Misalignment:

​

• Realigning panels at the toe and heel to ensure smooth operation

• Adjusting hinges, pivots, and rollers to evenly distribute weight

• Correcting track alignment

• Providing guidance on ongoing maintenance

​

By addressing both normal wear and installation-related issues, Pro-Lock restores AluK doors to smooth, secure, and reliable performance.
