Efflorescence is one of the most common, and often misunderstood, signs of moisture problems in a basement or crawl space. It appears as a white, powdery substance on concrete or masonry walls and floors. While it may seem like just a cosmetic issue, efflorescence is a red flag that moisture is seeping through your foundation. At Master Services, we offer a range of proven, brand-name solutions to tackle moisture at the source and prevent long-term damage to your home.
You may ask what efflorescence is even made of. Efflorescence is the crystalline deposit of salts that forms on surfaces like poured concrete, brick, or cinder block when water moves through the wall or floor and evaporates. As groundwater or moisture wicks through the porous material, it dissolves natural salts within the structure. When the moisture reaches the surface and evaporates, it leaves behind those salts as a white or grayish residue.
Efflorescence is not mold or mildew, but its presence often indicates the same underlying issue: water intrusion. Left untreated, this can lead to further deterioration of the material, musty odors, mold growth, and even compromised structural integrity.
Efflorescence won't harm your health, but it is a clear indicator that water is entering your home. Over time, persistent moisture exposure can lead to serios issues:
Addressing the cosmetic signs without fixing the root cause will only lead to recurring issues.
At Master Services, we don't just clean up surface-level symptoms. We eliminate the source of moisture to protect your home long term. Our proven waterproofing systems and products are designed to address all causes of water intrusion that lead to efflorescence.
CleanSpace is a heavy-duty, reinforced vapor barrier used to seal basement and crawl space walls. By creating a continuous moisture barrier, CleanSpace prevents water vapor from passing through the foundation walls, halting the process that causes efflorescence. It also brightens the space and helps to reduce humidity.
If groundwater is seeping through the walls or floor joints, our WaterGuard system is an ideal solution. Installed along the perimeter of the basement floor, WaterGuard collects water before it reaches the surface and redirects it to a sump pump system. This prevents future moisture buildup behind walls and helps stop efflorescence at its source.
Pairing WaterGuard with one of our sump pump systems ensures that any water entering the system is quickly and efficiently pumped away from your home. For added protection during winter months, we can include our IceGuard discharge line attachment, which ensures water can still escape even if exterior pipes freeze.
If you notice white, chalky residue on your basement or crawl space walls, don't write it off as a minor issue. Efflorescence is a key indicator that your home is being affected by moisture, and where there's moisture, there's serious problems. The good news? With Master Services' suite of industry-leading waterproofing solutions, you can take control of your home's environment and protect your investment for years to come.
