Visible Step-Down Between Old House and Newer Addition

A visible step or drop where the floor of an older NJ home meets a newer rear or side addition indicates the addition has settled. Homeowners commonly feel it underfoot or see trim separating at the junction.

Additions built without helical piers or deeper footings often drop half an inch to two inches in the first decade, especially on clay-heavy lots in towns like Westfield, Scotch Plains, or Cranford. Underpinning the addition restores level and prevents further drop.
