Hinge and bracket

This weekend we laid a load of floor tiles at my mother-in-law's. Today we got to the front door, which is a Point-P metal and uPVC frame affair. It's not too bad, but it's sagged a little, and with the new tiles laid we had to raise it a fraction, and bring it closer to square. 

Today's back blip is a shot of the hinge mechanism - which was adjusted successfully. Have I mentioned that I don't like DIY?
