So in my house the kitchen/living room is Amish laid tongue and groove oak. The subfloor is 3/4 inch plywood (not particle or flake board but real plywood), and there are a few spots that creak/squeak pretty good. So looking up from the basement.. whomever built this place actually used liquid nails between the subfloor and the joists. So my idea of being able to fill a crack or a lifting of the plywood from the joist.. shot to hell.So not knowing what else I can do I thought of this.. what about using a pretty tiny drill bit.. maybe .5 or 1mm drill a couple holes in the center of teh squeaky spots. Then using an applicator similar to this: http://bit.ly/2QHQOhY injecting glue below the oak but on top of the plywood?I realize it'd be difficult to gauge with real accuracy but assuming a top depth of 1/2 inch.. then possibly using the composition of the wood bits the drill bit creates I might be able to gauge when I've completed a pass through the oak. I could then go back over the hole with a nice, dark wood putty. I mean the hole will be very tiny so it won't take much to conceal it.Anyway you folks get what I'm going for.. what are your thoughts? How do the pros tackle speaky wooden floors? via /r/DIY http://bit.ly/2D6TJNN
