Visible Step-Down Between Old House and Newer Addition

A visible step or drop where the floor of an older New Jersey home meets a newer rear or side addition indicates that the addition has settled. Homeowners commonly feel the transition underfoot or observe trim separating at the junction.

Additions constructed without helical piers or deeper footings frequently drop between half an inch and two inches within the first decade of service, particularly on clay-heavy lots in municipalities such as Westfield, Scotch Plains, or Cranford. Underpinning the addition restores level and prevents further settlement.
