We have just moved into a new house and discovered that the previous owner had left the boiler condensate to drip into the external wall - the pipe had been snapped off about half inch inside the external face of the brickwork, and left long enough for the wall to go green. Even our surveyor mistook the issue for something else which I am not best pleased about.
We have had the pipe repaired but are now left with a small surrounding area of mortar that has gone crumbly / completely missing that needs repairing.
How can I best go about this - some is missing quite a way back, and there may even be a spot or two where it's missing all the way through the outer leaf.
I was thinking of a pointing gun to get the mortar into the joints, but was worried about sending some through into the cavity - most of it hasn't gone back that far but there definitely are a few spots where it has.
Also there is a plastic air brick in the affected area.
So :
what mix should I use (or a pre mixed product)
what tools should I use - pointing gun or similar?
or shall I just call in a pro - if so what "sort" of pro am I looking for?!
Thanks
