- 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.
