What to Do After Water Damage: First 24 Hours
Stop the water at the source if you can do it safely, shut off electricity to wet areas, photograph everything before moving items, and call a professional water damage team to begin extraction. Mold can start in 24–48 hours, so speed matters more than cleanup quality at this stage.

- 1
Shut off the water source
Close the supply valve to the failed fixture, or the main shutoff if you can't locate the source.
- 2
Cut power to wet areas
Use the breaker — never step into standing water near outlets or appliances.
- 3
Document everything
Photograph and video every affected area and item before you move anything. This is the foundation of your insurance claim.
- 4
Call a professional water restoration team
Extraction and structural drying in the first 24 hours determines whether materials can be saved or replaced.
- 5
Move salvageable items out
Lift wet items off the floor, take fabrics and electronics to a dry area, separate damaged items for documentation.
- 6
Notify your insurance carrier
Open a claim within 24 hours. Your restoration team can speak with the adjuster directly.
Safety considerations
- Never enter standing water near electrical outlets or appliances without cutting the breaker.
- Treat any water from outside, sewer lines, or unknown sources as contaminated.
- Don't run HVAC if water reached ducts — it can spread contamination.
Insurance & process notes
Sudden, accidental water damage from internal sources is usually covered by homeowners insurance. Surface flooding and sewer backup typically require separate coverage. Open your claim within 24 hours and keep all documentation.
When to call immediately
- Water is still actively leaking or spreading to additional rooms, ceilings, or lower levels
- The source is contaminated, unknown, or tied to sewage, stormwater, or appliance failure near electrical hazards
- Hardwood, finished basement materials, cabinets, or insulation have already been wet for several hours
Mistakes to avoid
- Waiting to call until after you finish mopping, which gives hidden moisture time to migrate deeper into floors and walls
- Running household fans across contaminated water or without a real drying plan, which can spread humidity instead of removing it
- Throwing away damaged materials before photos, readings, and scope documentation are captured for insurance
Chicagoland context
Across Chicagoland, water losses become mold problems fast because basements, seasonal humidity swings, and layered flooring systems trap moisture even after surfaces look dry. Fast extraction and real drying data matter more than cosmetic cleanup in the first day.
