UPVC Tilt and slide door problem

[Jivebunny]

I have a tilt-and-slide uPVC patio door that’s around 20 years old. It’s been very reliable over the years, and has been siliconed lubed on a yearly basis, recently I’ve noticed I now need to push the top of the door inward for it to fully close. There seems to be strain on the top levers of the door when closing.

The door still slides fine, but as it reaches the fully closed position it tilts inward. I cant remember if this was always the case. Previously, I could close and lock it just using the handle, but that no longer works unless I manually push the top of the door in first.

Any advice appreciated.

These things are very adjustable. For the price of a drink I'm sure that any uPVC fitter would be willing to come & look.

The problem likely stems from a slight sagging of the door leaf or a hardware adjustment that has shifted over time. On older PVC tilt-and-turn doors, the rollers or the upper stay often become misaligned, requiring the top to be pushed in to lock properly.
