I'm in the midst of my bathroom renovation. i put down an entirely new 3/4" plywood subfloor (attached with adhesive and screws). about 2 months later i got around to putting down 1/4"hardieboard with mortar and screws. yesterday, about 6 weeks later my floor has started to squeak along the tub. I still have not put the tile floor down. I'm not sure if it's the hardieboard/subfloor that is squeaking or the subfloor/joist that is squeaking. Before i put the tile on the floor i figured i would check for advice.
Not sure if i should just leave it and let it squeak or try to fix it. if i fix it...how??
