Our SaniDry™ dehumidifier & air systems

Even a basement with an effective waterproofing system can still develop moisture and mold problems and may feel damp. Concrete walls and floors continually absorb moisture from the soil and release it into the air in your basement, and store bought dehumidifiers simply aren't strong enough to solve the problem.

The latest generation of SaniDry™ dehumidifiers is more powerful and energy efficient than ever! Each one includes a comprehensive, written warranty upon installation. Each SaniDry™ installs with a powerful blowing motor that circulates dry air throughout the space, aggressively drying out your basement or crawl space. Collected water can be drained into a sump pump pit, a section of your perimeter drain, or away via a condensate pump. Our installers can provide you with either of these two award-winning dehumidifier systems:

We can help you create a drier, healthier home!

If you've waterproofed your basement, a reliable, low-maintenance dehumidifier system is a final touch that makes a big difference! You'll love how dry and clean our systems can make your basement feel! These systems work perfectly with our other basement waterproofing products or as a standalone option.
