Installing floating floor over squeaky wood floor- rip it up? (Q3)
Here's the other big question: the existing floor in my living room is oak t&g (5/8") over a diagonal plank sub-floor over joists. The home was built in 1955 and the floor has been carpeted since I bought the house 5 yrs ago.
When I pulled up the carpet, it revealed a pretty damaged hardwood floor-- hard to imagine what they did to it to ding it up that bad! Anyway, the major issue with the floor is that it squeaks badly and I'd like to take care of that before I lay the floating cork floor.
So my options are:
1) quick & dirty: locate the joists, run 3" screws through the existing floor and subfloor, which should pin down both the wood floor and the subfloor to the joists. But, yes, I know I know, wood expands and maybe this is a bad idea
2) not so quick but a lot dirtier- rip up the old wood floor, screw the subfloor back down to the joists (after 53 years a lot of the nails have worked loose, I'm sure), then glue/screw a new layer of 5/8" (OSB or plywood? opinions sought) on top of the sub-floor, THEN lay the floating floor.
3) Anything I haven't thought of?
PS- the basement is finished and I'm not interested in ripping up the ceiling to fix squeaks from below. Topside improvements are going to have to be good enough!
looking forward to your answers and thoughts-
