Diagonal Cracks Radiating from Basement Window Corners

Diagonal cracks radiating upward and outward from the top corners of basement windows are a classic indicator of differential foundation settlement. One section of the foundation is dropping at a faster rate than the remainder, and the window opening concentrates the resulting tensile stress.

In New Jersey homes founded on fill soils or near former stream channels, this pattern often appears on one side of the home before the other. Left untreated, the cracks widen and the window itself may rack out of square. Underpinning stabilizes the settling section and halts further movement.
