What we see in Florissant

  • Post-war block and poured basements commonly show horizontal cracks or bowing where clay soil presses on the wall. That needs a structural assessment, not just sealing.
  • Short downspout extensions and soil that has settled toward the house are frequent causes of leaks.
  • Ask whether wall anchors, bracing or excavation is recommended, and why.
