I purchased a townhouse built in '69 with on a cement slab I believe. The downstairs floor is warped. There was water damage through the walls that was ongoing (a tenant lived there for 12 years and didn't report the roof leaks which have now been fixed. The upstairs is level. There are no cracks that I see in the foundation outside or on the stucco, nor inside anywhere except a slightly sticking bathroom door, and where the built in mirror on the fireplace shifted a little. Could the floor be the result of the longtime water expousure, or maybe just the age? Are there any products that will level the floor without having to do heavy duty foundation work? Thanks.
