Basement Dehumidifier Installation & Humidity Control in St. Louis
We help homeowners take control of indoor humidity and create healthier, safer spaces—starting from the ground up.
Protect Your Home from Excess Moisture
Musty smells. Sticky air. Mold. If your basement or crawl space has too much moisture in the air, you’re not just dealing with discomfort—you’re risking damage to your home and health. That’s why our team at Perma Jack of St. Louis offers professional dehumidifier installation using powerful whole-home AprilAire systems.
Humidity is more than just a nuisance. When levels climb above 50%, mold, mildew, and dust mites thrive. These irritants can trigger asthma, worsen allergies, attract pests, and damage wood, insulation, and even your home’s foundation.`

Benefits of Installing a Basement Dehumidifier
Even though AprilAire units don’t have built-in air filtration systems like some all-in-one models, their powerful moisture control still makes a huge impact on indoor air quality—reducing allergens, pollutants, and airborne irritants that thrive in damp environments.
