I live in a log house with tongue-and-groove floors. The downstairs floor is prefinished and sits on a plywood subfloor with a thin foam layer in between.
However, the upstairs floor, while thicker, was unfinished and spans beams. We had to polyurethane it ourselves. The house is now about 10 years old and there are two boards that the person in the bedroom frequently have to walk across and they squeak now.
It's two boards and it's at the end of the board. I'm looking for the best, least visible solution to fix the squeaking. I haven't looked yet, but I'm sure I can get to the underside of the board from downstairs. The upstairs floor is the downstairs ceiling. It wasn't a good idea in retrospect, but it's what we're dealing with. There isn't a large crack do get into to do repair work. If there was, and there was something underneath that edge, I'd think just screwing it down would be the answer. I suppose if I had to, and there was a beam under the edge, I could screw from the top down and put wood putty over the screw head, but I think that would look bad.
Does anyone have a suggestion on how to correctly fix this issue? Thanks. I'll try to find out whether or not there is a beam directly under the edge of the two boards or whether they're hanging out over open space and post back here tomorrow.
