    at the corner of our house, at the bottom of the stairs, on one wall we have a wet patch.

    There is no black mould, but white stuff is accumulating (salts?). A surveyor friend reckons the render is in good condition. The waste pipe from the bathroom goes down the wall at this point but we can't see a sign of a leak. There is a small hole in the wall at second storey level. Also we think it's cavity wall but that no insulation has been put in. Please help

    Put an aluminium sheet below the leak and mak the water go down through the sheet without draining through the wall. which willl damage the entire house.

    If this wet spot is below grade then you might have a drainage problem.  Grade the land around your house so water drains away from the house.

    If the leak is above grade then you have a mechanical or structural leak.

    Whatever is causing the leak needs to be fixed because mold is on it's way.
