Efflorescence on the basement wall? Here's Who to Call
The chalky white crust on a basement or foundation wall is efflorescence — mineral salts left behind as water moves through the concrete and evaporates. The powder itself is harmless, but it is a signal that moisture is passing through the wall, which over time erodes masonry and invites mold. A foundation specialist can find where the water is entering and waterproof the wall so the problem doesn't return.
