Shut it off, kill the power, photograph everything. What you do in the first sixty minutes decides how the next three weeks go.
Stop the source
Main shutoff if it’s a supply line. Most Atlanta houses have it at the street or where the line enters the crawlspace. If you’ve never found yours, find it now, before you need it in the dark.
Kill power to the affected area
Water and outlets don’t negotiate. If the panel is dry and safe to reach, cut the affected circuits. If you have to stand in water to reach it, don’t — call the crew and the utility.
Photograph before you clean
Wide shots of every affected room, close-ups of standing water, soaked materials, and the source. Timestamped. This is the single highest-leverage thing a homeowner does, because a claim without before-photos is an argument you lose.
Then call
Not tomorrow. Water wicks into subfloors and wall cavities within hours, and mold growth can start within 24 to 48 hours of saturation. Every hour you wait moves the job from drying toward demolition.
