Weather coating cost for exterior walls

The render on our gable end takes a battering from the rain and never seems to dry out. What do installers charge for weather coating a whole house?

"Depends on the render , if render is not drying out I would suggest a breathable new render system, krend )old sand and cement render systems do not breathe application off a coating system storm dry can cause further issues internally and on my experience does not work, the material is holding far to much moisture and will need replacing at some point.

"I have had a look and it would cost around £4,000 depending on the type of house the price varies and also with the cost of materials"
