The problem with wooden floors (or wooden sub-floors) is they squeak.
if the wood is exposed, sweep TALIC powder over it, this will get down in the cracks and lubricate recducing or eliminating the squeak.
Wood, "Shrinks" as it dryes out, and it always dries out less it is under water.... In days of old, when I was bold, I was a ladder monkey.. We used mostly wooden ladders for assorted reasons.. Sometimes a ladder would get very loose and wobbly.. Soak it in the river for a short period and it would tighten right up.
(Do not, however soak it too long or it rots).
Home is where I park it!
