Damp Proofing

Wall taken over by Black mould

Jade 19/05/2026 - 8.00 AM

My 1930s semi has a kitchen extension added onto the back built in the 1970s. I saw black mould on the wall, I started chipping away and the plaster board is also black which google is suggesting is extension structural rot/mould. I can visually see the mortar on the external wall is damaged. Any suggestions on how to proceed? Wanted to get building works/further extension in the future but not right now so am open to suggestions on how to fix this problem (I have photos on request)

Without looking at the area as a whole it's impossible to say what the best solution is.
