Before replacing the carpet in my bedroom I cut the carpet and screwed down the sub floor to quiet down the squeaks.
Weeks later, the tiled floor in the bathroom adjacent to the bedroom now has a slight bulge upwards. The bulged area is about 6 inches away from the closest screwed down sub floor.
I guess screwing down the sub floor prevents them from moving horizontally due to moisture expansion.
If I cut slits between the sub floor boards with a circular saw, would that allow the floor to expand without bulging? Or should I just remove the screws and live with squeaks?
