Assess Basement Flood Risk Before Prolonged Heavy Rain

Cost Savings

Checklist Tasks

• Check soil grading to ensure water flows away from the foundation.
• Test sump pump by adding water and verify proper outside discharge.
• Clear debris from window wells and inspect for cracks or gaps.
• Inspect basement walls for efflorescence or damp areas signaling seepage.
• Seal foundation cracks with hydraulic cement to prevent stormwater entry.
• Confirm downspout extensions direct water at least six feet from house.
• Verify sump pump backup power to ensure operation during outages.
• Test floor drain by pouring water to ensure fast drainage and no backflow.
• Check basement plumbing traps for dry seals that may allow sewer gas or water in.
• Look for rodent or insect burrows at foundation that could channel water inside.
• Photograph vulnerable areas for insurance documentation before heavy rain.
• Install water leak sensors at the basement’s lowest point for early alerts.
