In high humidity and damp conditions, mold can begin to grow as quickly as within 48 hours – and its effects can be far-reaching. Not only is mold damaging to property, but it can also be hazardous to human health. Health symptoms associated with mold exposure include intensified allergies, headaches, respiratory problems, brain fog, and more.

It’s easy to note if your basement has a mold problem. From a visual standpoint, it’s hard to miss. It tends to have a powdery texture and appears as black spots on both porous and non-porous objects and materials. It also gives off a strong musty odor.

Other Common Symptoms

  • Mold or mildew growth
  • Dampness or wetness on walls or floors
  • High humidity readings

Root Causes of Musty, Smelly Odors in the Basement

  • High Humidity: Basements and crawl spaces tend to be damp areas of the home. If humidity levels are too high in these areas – let alone anywhere in the home – conditions can give way to moisture buildup and present ideal conditions for mold and mildew growth.
  • Foundation leaks: If there’s water in your basement or crawl space following any type of rainfall, it’s likely coming in through a crack or gap in the basement walls or floor. And wherever there’s moisture, there’s the risk of mold growth.

If you’re experiencing any of these concerns, schedule a free consultation to discover how you can eliminate these issues for good.
