Hi! My husband and I started our first flooring project... we are putting down solid wood floors. We pulled up the old flooring and the junky, flaky subfloor. (composite?) We put down nice 3/4" plywood as the underlayment/subfloor. (there are planks underneath the plywood that are on the joists) My question is: should we have left a gap around the perimeter of the room for the plywood? Right now in most places, the plywood is right up to the wall. Of course we plan to leave a gap around the room for the hardwood flooring. Than you for your advice!!!
