New Jersey Crawl Space Dehumidifier Installation

Installing Dehumidifiers in Central & Northern NJ and the Jersey Shore

It's easy to think of your crawl space as unimportant and isolated from the rest of your New Jersey home, but the crawl space directly affects the quality of the air you breathe. If your crawl space is a dirty, damp haven for mold and pests, the outside air that passes through your crawl space up to the rest of your New Jersey home will pick up contaminants that you will breathe in, which can irritate and even causes allergies.

A damp crawl space can lead to other issues like wood rot, water damage, foul odors, bug infestation, and colonization. Blue Umbrella Waterproofing installs AprilAire dehumidifiers to remove excess moisture, prevent rot, and discourage cockroaches, termites, wood-destroying insects, and other pests.

Thankfully, a crawl space can be kept clean, dry, and free of contaminants with professional crawl space dehumidifier installation and crawl space encapsulation by the experts at Blue Umbrella Waterproofing. With over 20 years of experience, we have the tried and true methods you need to ensure that your New Jersey home is safe and protected.

What Is A Crawl Space Dehumidifier?

If left untreated, your crawl space can become a damp, moist area that is an even better home for mold than a three-week-old slide of bread. Thankfully you can keep your crawl space from becoming a petri dish with a crawl space dehumidifier.

A crawl space dehumidifier, like a basement dehumidifier, is a machine designed to play two roles.

First, it keeps your crawl space dry. The dehumidifier pulls in the damp air from your crawl space, removes the moisture, and blows out dry air.

Second, it keeps your crawl space air clean. The dehumidifier runs the air it pulls in through a MERV 13 hospital-grade filter that removes dust mites, mold spores, pollen, dander, bacteria, and other allergens, expelling clean, breathable air. By maintaining the humidity at a safe level, the dehumidifier prevents mold from growing in your crawl space and keeping the air clean stops you from breathing in harmful allergens.

Unlike the small dehumidifiers you might see in the big box stores, a crawl space dehumidifier is much more durable. A crawl space dehumidifier can absorb far more moisture and maintain the air quality of much larger spaces than a store-bought dehumidifier.

Do You Need A Crawl Space Dehumidifier?

The short answer is yes. Crawl spaces in New Jersey are notorious for moisture and mold, and a crawl space dehumidifier is an essential part of complete crawl space waterproofing and crawl space encapsulation. Unfortunately, crawl space waterproofing or encapsulation without a crawl space dehumidifier is almost asking for mold to grow.

Preventing Water Damage & Rot

A wet crawl space can also cause damage in the form of rot, particularly wood rot. Many New Jersey homes have wood in the crawl space ceiling joists that you need to protect. By installing a crawl space dehumidifier, you can keep the moisture in the area low enough, so rot never occurs, helping you avoid costly repairs.

Keeping Bugs & Pests Out

Keeping your New Jersey crawl space dry also discourages bugs and rodents from moving in. Without a damp, wet environment, there are much less likely to be spiders, water bugs, centipedes, thousand leggers, crickets, cockroaches, termites, wood-destroying insects, and other pests making their home in your crawl space.

Besides preventing mold growth, a crawl space dehumidifier can help put a stop to:

  • Mold Growth
  • Foul Odors
  • Allergens
  • Wood Rot
  • Water Runoff
  • Water Damage
  • Inefficient Heating & Cooling
  • Costly Utility Bills
  • Bug Infestation & Colonization

How to Install a Crawl Space Dehumidifier in Your NJ Home


  1. Select the right crawl space dehumidifier. Keeping in mind the size of your crawl space, you need to find a dehumidifier that is up to the job. Remember, the types of dehumidifiers you might see in a store are far too weak for a crawl space. When you work with Blue Umbrella Waterproofing, our experts select a dehumidifier designed to handle crawl spaces and one capable of treating a crawl space as ample as yours. 
  2. Find the correct location. Next, find a spot in the crawl space to put the dehumidifier. You'll want a place where the dehumidifier can drain properly while effectively treating the whole crawl space. Other factors to consider include noise levels, the level of the ground, and the risk of standing water. Our crawl space waterproofing team ensures the dehumidifier is where it needs to be.
  3. Install and Adjust Settings. Once you've picked the right location, you'll also need to crawl into your crawl space and set up the dehumidifier. While the exact settings of your dehumidifier will depend on the type selected and your specific crawl space, it is common to aim for about 50% humidity. Our experts can help customize your dehumidifier settings, ensuring that the dehumidification levels suit your crawl space's needs. In addition, we provide maintenance services, so your crawl space dehumidifier is always running smoothly.

Is a Dehumidifier Enough, or Do I Need Crawl Space Encapsulation?

Here at Blue Umbrella Waterproofing, we highly recommend installing a crawl space dehumidifier as part of overall crawl space encapsulation solution. A crawl space dehumidifier in your New Jersey home will do a lot to keep your crawl space healthy and dry, but it can't address the core problem of your crawl space. Unless encapsulated, your crawl space is open to the elements, making it vulnerable to moisture, mold, and pests.

Crawl space encapsulation is the answer, sealing off your crawl space and the rest of your home from cold, wet, dirty outside air and moisture. Without encapsulation, your dehumidifier is like a sailor with a bucket trying to scoop water out of a leaky boat. It might be a big bucket, but it can't completely stop the ship from taking on water.

How Much Does a Crawl Space Dehumidifier Cost?

The cost of a crawl space dehumidifier can vary greatly, with larger capacity and higher quality dehumidifiers costing more. The price of your crawl space dehumidifier varies based on the model you need and depends on: 

  • The size of your crawl space
  • The amount of water you get in your crawl space
  • The energy consumption of the dehumidifier
  • If you have an encapsulated crawl space
