Efflorescence V.S Mold Growth

November 24, 2018 • Mold Remediation, Mold Removal, Prevention


Efflorescence is often mistaken as mold growth by Ohio home and business owners. Both efflorescence and mold occurs in damp environments and present similar growth characteristics. While efflorescence is not mold, it is an indicator of damp conditions, which can be conducive to mold growth if the moisture source is not properly addressed in a timely manner.

What is Efflorescence?

Efflorescence presents as a white and powdery substance. It is the result of water or water vapor seepage through your foundation walls, which forces soluble salts and minerals to the surface. These salts and minerals are then deposited on the surface of your foundation walls when the moisture evaporates, leaving behind a crystalline like structure. Efflorescence can look rather ominous and is often misidentified as mold by Cleveland property owners. Efflorescence is not mold, but it is important to understand that it is a sign of underlying water intrusion that could eventually create the ideal environmental for mold growth. If you notice efflorescence buildup in your basement or crawl space, you should address the underlying moisture issue to prevent additional problems like mold growth and water damage.

What Causes Efflorescence?

When water travels through the natural pores of your masonry walls, it carries water soluble salts and minerals. When the water on your foundation walls evaporate, it will leave behind salt deposits. Pinpointing the exact source of the moisture can be difficult, as numerous entry points are possible:

  • Foundation-leak-water-damage-cleveland-ohioGround water saturation– Capillary action can easily draw water from wet soil into masonry building materials.
  • Rain water– Either through a leak or through vapor drive.  This occurs when the sun hits a saturated wall and drives the moisture inward.
  • Sprinklers / artificial water sources– Occurs when sprinklers saturate an exterior wall, causing water to enter the wall and later retreat, carrying salts to the surface.
  • Water vapor– Airborne moisture forced through masonry walls can provide sufficient moisture to cause efflorescence. For example, during the winter months, warm, humid indoor air will move towards the cool exterior. Water vapors can settle on your foundation walls and leave behind efflorescence.

This is just to name a few key events that can cause efflorescence buildup in your basement or crawl space. If an underlying moisture issue is leading to additional issues like mold growth and water damage, you might need to consult a professional.
