What Is A Crawl Space Dehumidifier?

A crawl space dehumidifier is a device that removes excess moisture from the air in a crawl space, preventing issues like mold growth, wood rot, and pest infestation. Relatively low-maintenance crawl space dehumidifiers are an effective way of improving the air quality of your home.

When Should You Install
A Dehumidifier In
Your Crawl Space

Not all crawl spaces require a dehumidifier, but it's essential to be aware of the warning signs of a humid crawl space. To prevent potential problems in your home, look out for the following indicators:

  1. Stair Step Cracks

    Musty Odors

    One of the first signs of a moisture problem is a persistent musty smell emanating from your crawl space.

  2. Tipping or Bowing

    Warped or Damaged Wood

    Prolonged exposure to moisture in your crawl space can cause warping or damage to wooden beams, floor joists, and other materials.

    Unwanted Pests

    Excessive crawl space moisture attracts pests such as insects, rodents, and termites, making it essential to address the issue promptly.

  4. Horizontal or Vertical Cracks

    Mold or Mildew Growth

    Mold or mildew in your crawl space or other parts of your home clearly indicates high humidity levels and requires immediate attention.

Common Questions About Crawl Space Dehumidifiers

As a homeowner, you want to do what’s best to protect your home. That’s why The Basement Doctor is here to help with answers to your questions about installing and maintaining crawl space dehumidifiers:

How Much Does Installing A Dehumidifier Cost?

The cost of installing a crawl space dehumidifier in your home depends on various factors, such as the size of your crawl space, the type of dehumidifier, and any additional features required. The Basement Doctor provides FREE inspections to install a dehumidifier.

How Long Does It Take To Install A Dehumidifier?

The installation process of a crawl space dehumidifier typically takes from a few hours to a full day, depending on the crawl space size and the complexity of the installation.

How Much Does A Crawl Space Dehumidifier Cost To Run?
While installing a dehumidifier will slightly increase energy costs, these increases are often offset by your HVAC system’s reduced workload and increased efficiency. For example, when installed as part of a crawl space encapsulation system, the overall improvements offset any additional utility costs.
Does A Crawl Space Dehumidifier Require Maintenance?
At The Basement Doctor, we recommend routine filter changes (twice per year) along with annual cleaning of the coils and pump equipment. While some of our customers elect to perform this maintenance themselves, we offer an annual maintenance program to keep your crawl space dehumidifier operating at its best. We also provide a FREE crawl space inspection during our service visits for added peace of mind.
