The ground floor of my house has been extended at the front, and we had rain
leaking in earlier this month. It turns out that rather than being the roof
(thankfully) the rendering on the wall on the first floor had a few (long)
cracks in it, and the mortar between the bricks behind it was damaged.
I repaired the mortar, but whilst I was there I noticed that around the
cracks in the rendering, some reasonable sized areas (18" to 2' across) of
the rendering have started to come away from the wall, presumably due to the
rain/frost. (This is as well as the smaller bits I pulled off to get to the
What I was wondering was, is it worth chiselling off the damaged rendering
and patching it (trying to match the slightly bumpy pattern as best I can),
or should I just get rid of the rendering all together? Either way I'm
going to repaint it.
I don't want to go to the trouble of fixing it, to be told when we sell the
place that "rendering is the new stone cladding", but then I don't know how
much risk there is of me damaging the mortar if I get rid of the rendering,
and having to repoint it all.
Any advice would be gratefully received.
