Bifold doors misalignment within the frame

Repairs made to this 3 leaf bifold door system, constructed of aluminum.

This is standard setup for London homes, comprising 3 leaves, which fold back on themselves. Hinged to one side wall and concertinaing, whilst sliding on a rolling carriage with 4 high load wheels. These wheels can be steel, or nylon, with ball bearings which reduce the friction on rotation.

The main door to the bifold system was dragging along the track and not opening. The folding section did not slide properly.

Bi-Fold Door Maintenance

Doors like this can develop problems with the Rolling Mechanism, Tracks, handles, locks or general folding and alignment issues. We suggest regular maintenance of the doors to ensure trouble free operation of the system.

The repair of the bifold doors consisted of several issues that needed to be resolved. Firstly, they were not parallel to the frame. This has occurred due to the roller carriage becoming defective.

Correct function was restored to the apparatus by renewing the roller carriage unit, installed between the master door and the center door. The existing roller carriage had moved from its correct position on the frame, causing premature wear. In addition, the hinges to the master door, were re-installed, with the correct shims.

The ultimate aim of this job will be to ensure that all doors are realigned to correct the counterbalance of the concertina section.
