Squeaky hardwood floors
Hi Jason, I found this article that will show you how to fix those squeaky floors - https://www.diynetwork.com/how-to/rooms-and-spaces/floors/how-to-fix-squeaky-floors
Do you have flexing in the floor joists under the floors?
I have heard that if you find the boards that are rubbing together (that’s what’s causing the squeaking), and shake a little talcum powder or baby powder between those boards, it will eliminate the problem.
I've used both baby powder and cornmeal. It works short term.
