Once you’ve shut down the water source and electricity, you may be staring at puddles and wondering, “What now?” Now it’s time to assess and do water damage repair—and do it quickly! Wet materials start developing very serious problems like mold after around 24 hours. You don’t have time to wait.

Believe it or not, there are three types of water. The first type is “clean” water from rain, condensation, leaky pipes, and so on. It’s relatively harmless to clean it up yourself. But if you decide to seek outside help, it costs around $3.75 per square foot for basic cleanup (replacements not included). The second type is gray water, slightly dirty water from dishwashers, washing machines, clean toilets, and so on. And it may have some contaminants. But you can clean it up yourself if you remove it carefully and with proper safety gear to protect yourself. Professional cleanup cost rises to $4.50 per square foot.
