I recently found out that my 2-level home is built on 24 inch centers as oppose to 16 inch. As a result, I am noticing a few cracks in the wall, in addition to a slight decline of the floor in the foyer area. Also several closet doors are not closing properly and the front door (glass) tends to stick. I did call around to a couple of foundation repair companies and the estimates I was given were all over $6000. Is there any other way I can get this issue resolve cheaper.
