Tilt & Slide Balcony Door Maintenance in Bromley By Bow

This Hautau tilt and slide door in Bromley by Bow E3 Is Juddering when Sliding backwards and forwards. Also when putting back into the closed position it is problematic. The runners have become misaligned over time due to the weight of the door and will need replacing. Also because this door has been forced at the handle when attempting to close, the link rail gearing has been damaged and will need repairing.
