With reference to the article on fixing creaky floors: http://www.diydoctor.org.uk/projects/floor.htm
I believe that my particular problem is the t&g boards creaking under the stud wall. I have used soft wood wedges under the skirting boards and it appeared to fix it for a week or so. However, the creaking has returned. The article above suggests using gap filler after the wedges have been inserted. However, how much do i use? The article appears to imply that the gap between the skirting and the floor is filled, but don't i need that gap there for the carpet?
Any advise would be great, it's driving us mad and most of upstairs is like this!!
