From “sweating” pipes to water droplets forming in and around the HVAC unit and ductwork to wet insulation, any moisture forming in or around these places in the crawl space can be problematic.

It’s often the first sign of a bigger problem that should be addressed. And if water is left to pool up or drip down from where it’s forming, too much of it could lead to property damage and mold growth.

Crawl space HVAC condensation is especially problematic, as it could cause excessive moisture to build up within the system, rusting or damaging parts from inside out. This can cause premature system damage and lead to inefficient operation.

Other Common Symptoms

  • Musty odors
  • Mold and mildew growth
  • Rusting of metal items in the crawl space
  • Wood rot
  • Excessive humidity

Root Causes

  • High humidity: The damp nature of crawl spaces can pose certain challenges, including high humidity. If humidity levels are too high in the crawlspace – let alone anywhere in the home – conditions can give way to moisture buildup and subsequent mold and mildew growth
  • Foundation leaks: If there’s water in your crawl space following rainfall, it’s likely coming in through a crack or gap in the foundation. And when there’s moisture in your crawl space, it can damage property, building materials and more.

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