You really have done the right thing by putting lime render on your outside wall. This allows the wall to breathe.
Our neighbours put a waterproof coating on their gable-end, which they have to come onto our land to maintain. It would never occur to us to stop the workmen coming back to re-do it, over and over again! The only stipulation we make is that they clear up after themselves.
Both our and their house are stone built. Fingers crossed, we have lime render which should not need anything done to it for at least 10 years. I love the way it changes colour as it dries out and then when it gets wet when it rains.
We have no damp course and I would assume, not much foundation either.
