DPC before or after re-pointing? Damp can be a major issue in the home. Find answers to questions or post your own here.

Hi there

Question 1)
The cavity wall of my 100 year old terraced house is in need of a damp proof course.
The outside of the external wall is in a bad condition. Old mortar needs to be raked out, some bricks need replacing and the wall needs re-pointing.
Would the DPC best be installed before or after the wall has been restored?

Question 2)
I have hacked of the entire plaster throughout the house and wish to plasterboard the walls. Can I use foiled plasterboards for the walls affected by rising damp?

Thanks for helping.
