My (relatively new-build) flat has a balcony with a UPVC door. Ever since we bought it, the door scrapes/grinds against a metal plate at the bottom of the door frame (see pictures below - you can see the scratches on the metal plate) when you open it. It generally means that you have to give the door a good shove to get it open, accompanied by the sound of grinding. It is particularly bad when it's sunny (balcony is south-facing), which I imagine is down to the door and/or the metal plate expanding with the heat.
A couple of years ago I found online how to adjust the height of UPVC doors by turning some hidden screws inside the hinges. I did this and raised the door just enough so that it didn't scrape anymore, even in the summer. All was fine but then the problem started showing up again and now it's actually the worst it's been. The screws in the hinges are at their max so can't adjust them any further.
It does not appear that the hinges have moved (see picture) and the door is perfectly horizontal (measured using a level).
Any recommendations on what else I can do to fix this, or is it better that I call an expert to get it fixed?
Thanks
