The linoleum did not run under the old dishwasher, there was some
plywood under there. I've removed the plywood because it got damp and
I'm going to dry everything out and put some new plywood, maybe lay
some tarpaper then put some 2X4's or something else that will bring
the dishwasher (hopefully) up to the same level that the new floor
will be. Does that sound ok?
The new floor is a solid wood prefinished floor (teak)

Do you mean that there is probably more damage from the dampness? Is
the only way to tell to pull them out? The cabinets are oak.
Thanks

How bad was the dampness? Do the walls seem damp also along it?

Some folks might go a little overboard on 'damp control' due to their area
where it is more of a problem. In your case, it seems more like a slow leak
with some softened plywood. You didnt indicate 'totally rotted out' (which
may mean problems under it as well).

Is your area a particularily damp area? Like New Orleans or Norfolk area
which was recovered swamp?

I'm in Norfolk area. We know lots about damp control ;-) I wouldnt pull
the cabinets myself if they seemed ok. I'm also on slab construction
(almost everything here is) so there's no problem with minor leaks on slab.

We're in Massachusetts, there are wetlands/swamp about 400 feet behind
the house and the area is heavily wooded so yes it's a pretty damp
area. There was no rotting in the cabinets or plywood and the only
dampness was on the wood on the floor. Basically the cabinets under
the sink and the one holding the diswasher have no bottoms to them,
there is just plywood over the floor and this plywood was damp. The
cabinets themselves didn't seem bad at all.
I've going to leave the cabinets in and hope for the best.
Thanks
