I am looking at a house that with a crawl space (see image). The crawl space has the full height of a basement, windows and a door leading outside in the back. It has French Drains along the downhill base of the house and plastic lining covering a rock floor. I saw water on top of the plastic in a few places. The foundation walls are footing and stem walls (I think). They appear nice but have some vertical cracks in several places upon closer inspection. The house was built in 2002.
Is the water concerning given the French drains installed? Are the wall cracks normal for the crawl space foundation... should they concern me?
