Hi,
I have a condensation issue in my bedroom and guest bedroom, I know the solution is better insulation on the outside of the windows and possibly between the outside and the plasterboard. It is a flat built in 1997 and top floor (3rd floor), the issue is there as the window protrudes slightly as the outside wall is slate that is at a slight angle.
I am wondering what sort of tradesman I require for this before proceeding?
Thanks and regards,
Duncan
