I have a carpeted creaky 13 tread 40 year old staircase that I've tried to repair several times with the breakaway screw systems found in the squeak elimination kits using breakaway screws that screw into joists through carpeting. The method has not worked for me, and I am considering ripping the carpet off the staircase and rebuilding the stairs.
I have not been able to locate any middle of tread stringers under the plywood treads to secure the the loose treads. I have also had no luck screwing the screws into the risers.
Has anyone had this problem and resorted to removing the carpeting and fixing the creaks by rebuilding the staircase. Would appreciate any experiences fixing creaky stairs
