The nitwit alarm "engineer" has made a pigs ear of refitting the alarm sensor & magnet to our new uPVC windows in the utility room - they are neither straight, nor parallel. This is annoying my wife, who in turn annoys me...
I can easily refit them, but what do I do about the the screw holes the aforementioned nitwit has drilled? I'd get the alarm people back, but I really, really, really don't want to go through the ball-ache of finding another alarm company again.
Is there some way of filling them? Bear in mind I only want to move them a couple of mm.
