The Aluminium Bi-Fold system in Ladbroke Grove W10 is misaligned due to slight movement in the building. As a result the top of the frame is warping.
Due to movement in the structure, there are many issues with this Aluminium Bi-Fold system. On a functioning door set there should be a concertina movement. However these doors are unable to due to the pressure on the middle section of the top guiding track.
The doors are not locking correctly due to misalignment. In addition the far right door is stuck in the locked position. This is due to the gearing shoot bolts being damaged. The gearing will need replacing.
The first course of bricks on the RSJ will need removed to allow the lintel to be repositioned. This will enable more space which will result in the frame being able to be corrected.
It will be necessary to replace the roller carriage and realign the whole system.
