Had a call from a tenant of mine. We have a extention which has an exterior wall (single skin) which has suffered from damp for yrs. In the winter the outside wall gets soaked and penetrates inside to the interior walls causing water stains and the finish plaster to blow. The gutters are ok and there are no leaks around the window unit. THe pointing is solid but appears to be retaining a lot of moisture.
Externally i was thinking of hacking out old mortar and repointing. Then will a water ressitant render (krend etc) be any use once the repaointing has been done?
