We are buying an old (turn of the century) farmhouse. The floor sags in the middle of the house. I haven't put a level to it, but would guess that the floor is 4-6 inches lower in the center of the house than it is around the outside edges. Underneath is a short crawlspace (about 1-2 feet). There is a pile of rocks, that supports the middle of the house. What would be the process of raising the center up? How much trouble is the average do-it-yourselfer asking for when tackling this project? The house is 25' wide and 30' deep. The rock pile runs almost exactly down the middle of the house and has no mortar holding it together. There isn't a lot of room to work in the tight quarters. Let me know if I need to supply any additional info. Thanks!

I am thinking about using an interior channel drain system, such as the ones at Realdry.com or waterproof.com for one wall in a crawl space that has a small leaking problem along it's base, almost every spring when the snow melts. Has anyone used either of these with good results? I am leaning towards the waterproof.com method, since I like the idea it just seals to the floor, instead of attaching to the wall. Also, my sump is about 5 feet away in another room (that is always dry) from where I want to end this channel. I am thinking about trying to securely attach a small drain hose on the lowest part of the end plate of the channel that I would then run down into my sump. As long as I seal where this hose attaches, it seems like it should work. Any thoughts, advice or experiences would be appreciated on this. I am tired of learning the hard way! Randy.
