Today I had two Upvc alignments to do and both were equally some of the very worst. The first job had flag hinges so I was quickly able to access the alignment screw and re set the door only thing with this type of flag hinge is getting the cover back on and died with its screw…. a absolute nightmare!!!
The second job didn’t have flag hinges but it did have a small amount of correction but that had been used and the hinges were almost failed so it was better to remove the door and replace the hinges, a lot longer to do but the door is now hung correct and the mechanism working correctly.
