Had to change a rad in a downstairs bathroom today, terraced house built around the turn of the century.
Took the old rad off, old brackets nowhere near right for the new rad. Couldn't see any screws.
Turned out the wall had been rendered as part of a damp proofing 2 years ago - 4 mm of cement render applied over the face of the brackets! Not just that, the pipe clips were rendered into the wall as well.
So neatly done it was impossible to see which edge of the bracket was the right angle. Much hacking about & filling later I got it sorted.
The mind boggles - the time it must have taken to neatly render over/around things must have been about three times what it would have taken to remove/refix them!
Mustn't grumble though, got paid for the extra time.
