Stop Basement Flooding When Drainage Fails

Cost Savings

Checklist Tasks

• Check basement perimeter for damp spots indicating new water entry.
• Deploy plastic sheeting and sandbags along pooling walls for a temporary barrier.
• Seal visible cracks in walls or floor with hydraulic cement to block leaks.
• Elevate appliances and valuables above floor level to reduce water damage.
• Install a portable sump pump at the lowest point and route discharge away.
• Check and clear floor drains of debris, test for backflow or blockage.
• Place water alarms in corners for early warning of rising water.
• Redirect downspouts and gutters to carry runoff at least 10 feet from the house.
• Turn off basement HVAC or furnace if water approaches to prevent electrical danger.
• Seal around pipe penetrations with expanding foam to prevent water bypass.
• Take photos of entry points and mitigation actions for insurance or repairs.
• Monitor exterior grading and dig emergency runoff channels if needed.
