Crawl Space Dehumidifier Installation in NJ, PA, and NYC

High-performance dehumidification & air filtration for your crawl space

rotted crawl space

Moisture damage. A crawl space that doesn't have proper airflow will have problems with moisture, mold, and wood rot.

Humidity and condensation in a crawl space is a recipe for disaster. Excess moisture leads to mold growth, wood rot, and foul odors, causing issues for your home's health, air quality, and value.

At Quality 1st Basement Systems, we specialize in preventing these problems with our patented crawl space dehumidifier. As part of our complete crawl space encapsulation system, a dehumidifier will ensure that your home has clean, dry air and help protect your crawl space from mold and other damage.

If you've had issues with mold, wood rot, or other crawl space humidity problems, call us today at 1-732-697-0557 or contact us online to learn more about how we can help! We offer free estimates on all our work in Philadelphia, Freehold, Edison and throughout the surrounding areas in New Jersey & Pennsylvania.

How humidity affects your crawl space

the stack effect

This diagram of the stack effect shows how cool air is pulled in through the lower levels of your home (click to enlarge)

Homes have never been completely airtight structures, and over the years outside air is given more and more access through both the changes you've decided to make to it and the natural decay of building products. This allows humid air to get into your crawl space, where it inevitably condenses and begins to cause problems.

Warm air rises and exits through upper windows and the roof, creating a vacuum in your home. In below grade spaces, this void is filled with humid air drawn from the outside. Once in your crawl space, this air condenses and leaves standing water before it works its way up and out of the home. Known as the stack effect, this process will worsen over time and create mold and wood rot while hurting your energy efficiency.

At Quality 1st Basement Systems, we solve these problems with our crawl space encapsulation system and crawl space dehumidifiers. By sealing your crawl space off from the outside, we can create an environment that remains dry, clean, and healthy, as well as far more energy efficient.

  • SaniDry™ Sedona Dehumidifier

    SaniDry™ Sedona Dehumidifier

    The SaniDry Sedona offers giant performance in a small package. It's the world's most efficient, high-performance dehumidifier, without a bulky heat exchange core. The Sedona easily fits in small crawl spaces, yet has a powerful blower to effectively dry large crawl spaces. Mold and mildew are common in crawl spaces, but the Sedona keeps the relative humidity below 55%, so mold won't stand a chance. As a high-efficiency dehumidifier, the Sedona removes more moisture (100 pints per day) for less electricity cost than conventional models.

    The SaniDry Sedona dehumidifier drains automatically and has a humidity sensor that monitors the air, so once it's installed, there's nothing else to do. Your crawl space will be drier and healthier - and so will the rest of your home too!

    Typical dehumidifiers simply can't handle the crawl space environment. They're bulky, inefficient, and don't remove enough water for the price you pay.

It can remove up to 109 pints of water per day, maximizing efficiency and effectiveness.

    By installing a SaniDry™ with a crawl space encapsulation system, you can ensure that your crawl space will remain dry and clean. A dehumidifier is essential to preventing mold growth, foul odors in the crawl space, and condensation.
