At Lowcountry Basement Systems we focus on solving moisture, mold issues, and even flooding in crawl spaces. Moisture, mold, and flooding issues in crawl spaces are caused by ground moisture, thermal break, and infiltration of air. Although the solution to crawl space issues varies from case to case, whether it be adding a dehumidifier, seal your crawl space, or installing a sump pump in your crawl space. Lowcountry has the solution to reduce crawl space humidity in your home.
In this episode of “Ask the Expert”, a customer from Allendale, SC asks Rob Videon about the origins of a white powdery substance that is covering his basement walls. Could it be mold?
Rob explains that the white, powdery and sometimes sparkly substance that commonly appears on basement walls is not mold, but efflorescence – a tell-tale sign of ground water seepage through basement walls. The minerals in that water are deposited on the wall surface and that mineral buildup is what we know as efflorescence.
While efflorescence is not harmful, the drainage problem that is causing the water seepage and the efflorescence should be dealt with right away. If left untreated, it can lead to mold problems, more serious leaks, basement flooding and even structural damage to the foundation itself.
