Draft proofing hole

[Dougie212]

Hi there.

I have just pulled out our kitchen units and discovered behind the sink a hole in the plaster board exposing the brickwork. The draft coming through the hole is quite alarming. Its an old house and appreciate that probably the pointing needs fixing and stuff... but before I put the new units in I'd like to stop the draft coming through the hole... My first thought was expanding foam but then I was concerned about the pipework in the future needing repair/replacement. My second thought was stuffing in rock wool and getting as much in there as possible.... but then with the pipework being a bit all over the place I don't know how I would finish it...... Ive attached a picture, so if anyone could help out with the best way to sort I'd be really appreciative!

Thanks as always
Dougie

That is a serious hole!
Easiest option is to screw a carefully cut board (or boards) with mastic to the wall or to build up the wall in bits to seal it

It’s horrible isn’t it!! Would you recommend expanding foam in the hole out to the outside tap??

Avoid foam that is a compression joint you may need access to it sometime , go with the rockwool if it is being covered with a unit as Tigercubrider says cut a cover for it if you want to leave it neat.
