Sinkhole Warning Signs

Sinkholes rarely strike without giving some warning in the surrounding environment or in a nearby home.  Here are signs to watch for that may indicate a problem:

  • Trees or fence posts that tilt or fall
  • Foundations that slant
  • New small ponds that appear after rain
  • Cracks in the ground
  • Sudden drainage of a pond
  • Rapid appearance of a hole in the ground
  • Dips, depressions, slopes that appear in a yard
  • Dead patches of grass or plants
  • Sinkholes in the neighborhood
  • Wilted vegetation in a limited area
  • Well water that is discolored or contaminated with debris
  • Cracking or buckling of home’s concrete slab
  • Presence of odd bugs like slugs and centipedes in the home
  • Earthy odor in home after rain
  • New or widening cracks
    • Separation between walls and ceiling or floors
    • Cracks in interior walls
    • Cracks around door and window frames
    • Cracked grout between tiles
    • Cracked tiles
    • Stairstep cracks in blocks or bricks
    • Uneven floors, warping of hardwood, bulging or sagging sections
    • Doors or windows that don’t open or close easily
    • Cracks in sheetrock near doors or windows

All homes are subject to some settling.  Any of these signs could exist without the presence of a sinkhole; however, the presence of one or more calls for further careful observation and an abundance of caution.
