At Crawl Space Ninja Supply, we often say the #1 enemy of a crawl space is humidity. The problem is you usually don't notice it until it starts causing musty odors, mold growth, elevated moisture levels, or poor indoor air quality.

Most people think mold is the problem in a crawl space…
But it’s really not.

Humidity is.

Mold, musty odors, wood rot all of that starts when crawl space humidity isn’t under control.

And honestly, we kept seeing the same thing over and over…

Homeowners would invest thousands into crawl space encapsulation,
only to skip a proper crawl space dehumidifier or buy a cheap one that breaks within 6 months
and a few months later, the issues start coming back.

That’s exactly why we built the Crawl Space Ninja® Dry Pro 70 Dehumidifier.

We wanted a crawl space dehumidifier that was actually designed for this environment

Something that just does its job:

• Controls crawl space humidity year-round
• Protects your home’s structure and subfloor
• Improves air quality throughout the home
• Completes your crawl space encapsulation system the right way

If you’re encapsulating your crawl space or already have this is the part you don’t want to overlook.

Want to know why we built the Ninja Dry Pro 70 and how it fits into a complete crawl space system?

Most homeowners never check their crawl space dehumidifier because they don’t want to crawl under the house just to see if it’s working.

These units allow you to monitor, control, and verify your crawl space humidity right from your phone. You can see if the unit is running, check humidity levels, and make adjustments without ever going under the house. It’s one of the easiest ways to make sure your crawl space stays dry and your system is actually doing its job.

The best part is DIY homeowners can install these. If you can run a drain line and plug in a unit, you can install one of these systems and start controlling the humidity under your home.

If you’re thinking about upgrading or installing a crawl space dehumidifier, give us a call and we’ll walk you through how to get 20% off any dehumidifier.

We’re happy to help you pick the right unit and show you exactly how to set it up.
