What we see in Chesterfield

  • Hillside lots and walkout basements are common, and water running downhill toward the house is a frequent cause of basement leaks.
  • Poured concrete walls in newer homes often show thin shrinkage cracks that are usually cosmetic. Ask the contractor to explain which cracks are structural and which aren't.
  • Sump pumps work hard on sloped lots during long spring rains. Ask about a battery backup.
