Hi, we have this external wall and the mortar is discolouring and becoming slightly flakey (more so in the bottom right of the picture). It is a Victorian terraced but the previous owners rebuilt this wall (some reason used smaller bricks and massive mortar joints). Anyway, we want to render the wall but want to address this issue first. Internally there are kitchen units and a plastic damp membrane so no issues with damp inside. But not sure what trade we need in (we rang a damp company we’ve used before but they say they only deal internally). Is it a builder? And do you know the remedy so we sort of know what to ask about to get them to come round for a quote.
I can’t see a DPC or any DPI holes. If needs a DPC can these bit fitted retrospectively? I wondered if it could be the drain leaking but the older bricks and mortar round the corner look fine. There are no air bricks on this length of wall too, but there are 3 that run along the other kitchen wall (the corner with the 3rd pic)
Cheers
John
