Hi everybody, this is my first post here and I am very new to doing home renovations. I'll explain my situation: My wife and I bought a trailer a couple years ago and in one of the rooms that we don't use we ignored the corner that is sagging down. Now that we found out that our first baby is on the way we need to fix up the room and make it into a baby room. The corner where the floor is sagging is around 2ft x 2ft. I don't really want to rip up the floor to fix this, but if i have to I will. I can get underneath the trailer, but its not possible to get to the floor from underneath. Also, we want to put down laminate floor once its fixed.
