House repairs

I don't know much about rendering issues but I'd be wondering if they applied a waterproof coating and that actually stopped the wall drying out to some degree so the damp stayed in the wall inspite of the repaired rendering.  But I'd also be checking the drain pipes to make sure the initial diagnosis was correct.  The damp might be caused by something other than cracked rendering.

But I totally agree that I'd have asked for a discount rather than trusting vendors who are going to be moving out of the building (so the motive to repair properly is weaker than if they were going to be living there for another 10 years) to do the repair.

You are new to all this. Damp and its rectification is an area of endeavour populated by purveyors of snake oil and a just few honest and informed people, so finding your way through it is a minefield.

Nowhere in your post did you mention the age of the property or the type of wall construction, but that's where reputable surveyors would start, along with a visual inspection of external features, like guttering and ground levels. There will be a remedy, but there seems to be a slim chance that  whoever did this work applied it. Perhaps it's only another area of blown render, but equally, it could be something else altogether.

Anyway, Adrian's post sets your situation out clearly and asks a relevant question.

To be fair, they probably lived with it and had as much idea of appropriate action as the OP, as well as little incentive..
