What is Efflorescence?

Efflorescence is the dried-up salt deposits that are left behind in your basement from evaporated leakage. It is safe to have efflorescence in your basement. However, it is a red flag that you have a leak in your basement. If you notice a powdery substance on your concrete, then it is unlikely that it is mold, and more likely that it is efflorescence. Still, you should have a professional assess your basement for leaks and other types of water damage. Because, chances are if you’re seeing efflorescence, your basement is most likely suffering from a water problem.
