How to Know if a Foundation Crack in Your Home Is Serious

By: Danny Lipford

Most cracks in slabs are small expansion cracks that should not pose a problem. If the crack will show, it can be filled with a concrete repair caulk. However, if the crack is 1/4” wide or wider, and one side is higher than the other, you may have a settling problem that should be examined by a structural engineer.

    I live in Hacienda Hts., CA, and have noticed the home I rent a room in has cracks that are getting larger and the main beams in living room are buckling and are getting worse by the day. Should we be worried? And do other residents in my area have the same worries??
