screwed down squeaky sub floor, causes warped sub floor
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? |

Talcum powder is a good remedy for squeaky floorboards. From what I've read, you sprinkle the powder on the floor then sweep it around so it gets into the cracks. ^_^ http://lifehacker.com/163667/macgyve...-talcum-powder http://www.thisoldhouse.com/toh/phot...886389,00.html http://www.hardwoodinfo.com/articles/view/pro/28/242 [8~{} Uncle Squeaky Monster |

They probably didn't leave the required gaps between sheets to allow for expansion. Still seems unusual that just screwing it down more would cause this. I'd certainly try doing a relief cut, you would think that would work, if that's the source of the problem. |

In my former house, adding a sub floor, used T&G 3/4" ply with liquid nails (joist) before the floor was nailed down. Solid. Without that, a good sub floor _would_ have a ~3/16 - 1/8" gap between plywood sheets at the end joints. |
