I am a 21 y/o college student and my fiance and I have just purchased our first home. She works at a bank and we purchased the property through a foreclosure at her bank and got a really good deal. We don't plan on living in the house for another year or so. In the meantime, it really needs a lot of work. The home was built around the 1930's has the original wood foundation and subfloor. Needless to say, this all needs to be replaced. Me and my dad are planning on doing all the work ourselves since he can do about anything. The problem is, there is an underground water route the passes directly through the middle of the house and heads straight for a well next to the house. So there is always moisture under the house. The crawl-space is very small with no moisture barrier (maybe 2 feet from the floor and smaller in some places). So here is my question: Would we be better off taking the floors up and manually digging the dirt out from the top, increasing the crawl space an additional couple of feet, and placing plastic down to decrease moisture. In addition to placing a tile at the back of the house where the water runs. We would then scab on and reinforce the joists and put down advantec for the subfloor. Also, install more air vents in the foundation. Or, would be better off pouring concrete one room at a time for the subfloor and foundation to know we wouldn't have to worry about water. Any input would be greatly appreciated.
