Foundation health is critical to the well being of your home. There are 3 types of foundations: footer/slab, Foots/ joist and footer/basement. All need to be considered separately, but there are common things to look for such as cracks, moisture and sagging. only a licensed structural engineer can advise as to the soundness of a foundation, not a home inspection personnel. When looking for yourself, look for cracks around the base of the home, in sidewalks near the home, puddling in a crawlspace, mold or any issue that seems out of context.
