What is the best way to seal bottom plates to subfloors when framing? In my current house, I went around and caulked after the walls were up. Is it better to put a sealant on the bottom plate before raising the wall? How about a 1/4″ Sill Seal like Denarco makes? Or an EPDM gasket? My walls are 2×8. I don’t want to spend huge amounts of money, so what is most effective, and cost effective?
