I've recently moved into an apartment that must have the creakiest floor in the world. The entire thing is wall to wall carpeting. I've been using a stud finder to attempt to locate floor studs and then driver finish nails through the carpet and then countersink them below the carpet. It works great when I can find a stud, but finding them is turning out to be hit and miss.
Does anyone have an error proof way of finding the floor studs that I can try? I'm about at the end of my rope.
