Foundation Warning Signs Every LI Homeowner Should Know
The ten visible signs of foundation trouble every Long Island homeowner should recognize before they become expensive.
Foundation failure rarely happens overnight. It starts with subtle signs that homeowners miss or dismiss. Here are the ten most common early warning signs on Long Island:
1. DOORS STICKING OR NOT LATCHING — especially when they were fine a year ago.
2. STAIR-STEP CRACKS IN INTERIOR DRYWALL — usually originating at door and window corners.
3. WINDOWS THAT WILL NOT CLOSE — or have recently developed uneven gaps.
4. SLOPED OR UNEVEN FLOORS — a marble rolls across them. A level shows more than 1/2 inch variation in 10 feet.
5. VISIBLE BASEMENT OR CRAWL SPACE CRACKS — especially horizontal, stair-step, or growing cracks.
6. BOWING OR LEANING BASEMENT WALLS — even subtle inward deflection.
7. EFFLORESCENCE (WHITE POWDER) ON BASEMENT WALLS — indicates water moving through the wall.
8. GAP BETWEEN THE HOUSE AND ATTACHED PORCHES OR CHIMNEYS — indicates differential settlement.
9. EXTERIOR BRICK OR BLOCK CRACKS — especially stair-step cracks in corner masonry.
10. BASEMENT WATER — seasonal or storm-related. Hydrostatic pressure causes structural damage if unaddressed.
Any three of these together is worth a free assessment. We'll tell you honestly whether it's structural or cosmetic.
