Why Humidity is Your Crawlspace's Worst Enemy

Even with a proper vapor barrier installed, the natural dampness of the earth and the temperature difference between the crawlspace and the living area can cause humidity levels to soar. When relative humidity exceeds 60%, mold begins to grow and wood begins to rot.

Improves Air Quality

Since much of the air in your home rises from the crawlspace, dry air below means cleaner, healthier air above.

Energy Efficiency

Damp air is harder to heat and cool. Lowering humidity reduces the load on your HVAC system, saving you money.

Prevents Rot

Keeping the wood joists under your floor dry ensures they retain their structural integrity for the life of the home.

Commercial-Grade Solutions

A standard dehumidifier from a hardware store is not designed to operate in the cool, damp environment of a crawlspace. They will quickly freeze up or burn out.

  • Energy Star rated for maximum efficiency.
  • Self-draining directly to a sump pump—never empty a bucket.
  • Powerful enough to dry large crawlspaces quickly.
  • Auto-defrost prevents freezing in cooler temperatures.

Professional Installation

Our team seamlessly integrates your new dehumidifier into your crawlspace encapsulation system for zero-maintenance operation.
