So I have a 100 year old house that I want to install laminate flooring in.
There was carpeting which I removed, and pulled out the baseboards (they had carpeted the baseboards!) so what's left is the original planks on top of the joists.
The original flooring I'm guessing is quarter sawn pine/fir. A lot of the boards are pretty mangled from electrical work, some are splintered like they literally ripped them up. There are also a lot of screw holes, cross-cuts, and the cracks are pretty drafty over the front porch, so I've kind of already decided not to refinish them.
So my question is, should I put a layer of plywood down to even out the floor first, or can I get away with just an underlayment?
Another consideration is I'm trying to keep the total thickness to 1" to meet the height of the beveled marble threshold to the bathroom.
Would 3/8" plywood be enough? Would I screw through to the joists, nail to the boards, or float the ply?
Thanks!
