I have wood floorboards under the carpet that I'd like to level. Underneath them are the joists. What would be the best way to go about this?
I was thinking I'd lift them, place shims on the joists and then put down plywood sheets instead to serve as the new sub floor. I'd also place insulation underneath the 1st floor as the house doesn't have much.
Any insight into how to tackle this would be great!
