I had a boiler installed (first floor) and the external pipe leaked onto the wall outside, making my downstair's neighbour's bedroom wall damp. It was a low level leak but continuous through the thin pipe for a few days before we realised.
The interior wall was damp for days before drying out (though it was July). The neighbour wants to check it doesn't need damp proofing before painting again because it's still damp and especially as it's a Victorian house with old bricks and mortar.
I'm surprised it's still damp given the level of leak. Should I get an independent damp surveyor and then get it treated accordingly?
