(Sorry to interrupt, with some actual DIY)
Our little used UPVC front door had begun to catch a little on the bottom frame cushion, just it was about to close. Not wear, more likely the hot weather causing distortion. The three hinges didn't match anything I could find online, to suggest how to go about adjusting them, but I could see a small rod, with a hex on it, between the frame part and the door part of the hinge. Nothing I had in the way of spanners would go in the arrow gap to the hex.
I dug out an old imperial open ended spanner, a touch to small in the jaw, thinned it's thickness down on the grinder, so it would go in the narrow gap, then opened its jaws up to fit the hex. A quick tweak on the adjusters and the door closes perfectly now. Saved calling 'a man' in and maybe £150. Spanner marked up, should it ever be needed in the future.
