Sixty minutes that decide how bad a basement flood gets

Discovering water across the basement floor is upsetting, and the first hour largely decides how much damage follows. The order of business: stay safe, stop the source, rescue belongings, and record the scene for the insurer.

Safety before anything

Keep out of water that may be touching outlets, cords or appliances. If the panel can be reached without wading, cut power to the basement circuits; if not, phone the electrical utility.

Stop the source

If a pipe is spraying, shut the house valve.
If the grate is rising, stop all water use upstairs.
Check the sump is running and has power.
Clear downspouts and window wells outside.
Call a plumber with what you have found.

Rescue and record

Photograph water levels and damage before moving anything
Carry valuables upstairs
Raise furniture on blocks
Phone the insurer early

One more thing

Once the source is stopped and everyone is safe, start removing water. A wet vacuum handles small amounts; larger floods may need a pump. Open windows and run fans and dehumidifiers to start drying.

Pull up wet carpet and underpad as soon as possible. Underpad soaks up water like a sponge and is rarely worth saving. Carpet can sometimes be dried and cleaned professionally.

Drywall left soaking past the second day frequently has to be trimmed away above the water line to prevent mould. Your insurer or a restoration company can advise on what to remove.
