Basement Flooding Emergency — Act in the Next 60 Minutes
Standing water in your basement? Follow this exact sequence: safety first, pump planning, documentation, and when to call IICRC-certified pros before mold starts.
Emergency checklist
Do NOT enter a flooded basement if water may have reached electrical outlets — cut power at the main breaker first
⚠ Electrocution risk is the #1 basement flooding hazard
Identify the water source: groundwater seepage, sump pump failure, sewer backup, or supply line break
⚠ Sewage backup (Category 3) requires full evacuation until decontaminated
Photograph water depth marks on walls, damaged items, and the entry point before pumping
⚠ Insurance adjusters need pre-cleanup evidence
If safe and Category 1 water: use a submersible pump to remove standing water — never use a household vacuum
⚠ Pump toward a drain away from the foundation, not into the yard toward the house
Call an IICRC-certified restoration company — basement flooding requires commercial dehumidifiers and moisture mapping
⚠ Consumer dehumidifiers cannot dry concrete walls or subfloor in time
Call your insurer immediately — ask if sewer backup rider applies if water came from floor drain
⚠ Standard homeowners insurance does NOT cover groundwater flooding without flood insurance
