Do not

  • Use a household vacuum on water
  • Turn on ceiling fans in wet ceilings
  • Throw items away before documenting them
  • Sign anything you do not understand

The notes that help later

Write down when you noticed the problem, what you saw and who you called. Keep these with your photos. A few lines made on the day are far more reliable than memory a month later, and they make insurance calls much simpler.

If you rent or live in a condo

Tell your landlord or building manager as soon as the water is under control, and do it in writing as well as by phone. They may control the shutoff, and they usually need to arrange work on the building. Your own insurance, if you have it, normally deals with your belongings. If the water came from a neighbor, let them know right away too, because they may not realize.

Questions

Questions about the first hour

What should I tell the contractor?

Say where the water came from, how long it has been there, how big an area is wet, and whether it is clean.
