Working on renovating this 40 year old house and my husband says this underlayment doesn't have to be replaced. He's only going to replace the parts where there are water stains. It's particle board and in this particular room it looks like there are mold spots everywhere? Or maybe it's just dirty glue, not sure. He says it's sticky! I guess I'm just grossed out that we're not going to replace it all. We're trying to save money but I just wanted your opinions! We're going to put LVP flooring downstairs and carpet upstairs!

We have a 5'x10' wood "Landing Zone" in our garage. Basically a deck that allows you to leave shoes and stuff before entering the house. It has 3 steps that lead up to it. It is constructed just like a deck, yet the flooring is just 1/2" plywood. We are going to cover it with some 8mm waterproof laminate. The steps and railing will just be painted with the steps also getting rubber treads. My question is how to deal with the edges of the flooring at the edge of the deck. There are two exposed edges. I am thinking of just installing stair nosing all around, but not sure. The flooring is inexpensive (lowes), sadly, I did not see any dedicated stair nosing that matched. All they sell are the "4 in1" trim kits that are about 78" long and cost as much as a carton of flooring.
