Your request is in. A local coordinator will call you back within minutes — 24 hours a day, weekends and holidays included.
If you can do it safely: shut off the water source if a pipe is involved, cut power to any room where water is near outlets, and take photos and video of the damage for your insurance file before moving anything. Standing water does its worst damage in the first 24 to 48 hours, and your call is already in motion.
If your situation gets worse — rising water, a sewage backup, or water near your electrical panel — send the form again and note the change, and a coordinator will flag your request as urgent.
