Save Your Crawl Space with a Dehumidifier

It seems like we spend a lot of time talking about crawl spaces, but that is because this often overlooked part of your home is so crucial to its stability and proper functioning. The truth is that the condition of your crawl space significantly impacts the overall health and comfort of your living environment. In terms of home health, a dry crawl space is a happy crawl space. Water and humidity are the enemies here, and one sure way to maintain a healthy crawl space is by installing a dehumidifier. 

A dehumidifier is a mechanical device designed to remove moisture from the air until the relative humidity is reduced to the desired level. There are several benefits to adding a dehumidifier to your home's crawl space. 

1. Moisture Control

Crawl spaces are prone to excess moisture due to their proximity to the ground and lack of ventilation. This moisture can seep through the soil, leading to damp conditions. By effectively reducing humidity levels, a dehumidifier prevents the buildup of moisture. This is crucial in maintaining a dry and stable environment, reducing the risk of structural damage and mold growth.

2. Mold and Mildew Prevention

High humidity levels create the perfect environment for mold and mildew to thrive. These fungi can cause significant health problems, including allergies and respiratory issues, as well as structural damage to your home. By controlling the humidity with a dehumidifier, you minimize the risk of mold and mildew development, ensuring a healthier living space.

3. Improved Air Quality

Moisture in the crawl space can lead to musty odors and poor air quality, which can permeate the rest of your home. A dehumidifier helps to maintain clean and dry air, improving the overall air quality. This is particularly beneficial for individuals with allergies or asthma, as it reduces the presence of allergens and irritants.

4. Enhanced Structural Integrity

Excess moisture in the crawl space can lead to wood rot and deterioration of your home's foundation. By maintaining appropriate humidity levels, a dehumidifier helps protect wooden beams, floor joists, and other structural components from damage. This not only extends the lifespan of your home but also saves on costly repairs in the long run.

5. Energy Efficiency

A dry crawl space contributes to a more energy-efficient home. When moisture levels are controlled, your HVAC system doesn't have to work as hard to maintain a comfortable temperature, leading to lower energy consumption and reduced utility bills. Additionally, a dehumidifier can help prevent the growth of mold and mildew in HVAC ducts, ensuring efficient operation.

6. Pest Prevention

Damp environments attract pests such as termites, rodents, and insects, which can cause extensive damage to your home. A dry crawl space creates an inhospitable environment for these pests, reducing the likelihood of infestations.

Signs that you could benefit from a crawl space dehumidifier

  • Unpleasant smells and musty odors

  • Water damage

  • Mold growth

  • Creaky doors, windows, cabinets and floors

  • Pets in your home and/or crawl space

  • Nothing seems to get dry

If you notice any of these symptoms, adding a dehumidifier to your home's crawl space might be just what you need. Depending on the size of your home, you can expect to pay from $200 - $500 for a basic residential unit, plus labor costs, which can run another $200 - $500 depending on the job. While several different brands of dehumidifiers are available, we often recommend Santa Fe for their quality construction and consistent positive reviews and performance.

Investing in a dehumidifier is money well spent because, along with protecting your home's structural integrity and improving energy efficiency, you will benefit from improved air quality and a fresher-smelling home. 

Maintenance

Installing a crawl space dehumidifier is not what we would categorize as a DIY project. 

Advanced-level electrical wiring is required, and it really should be professionally installed. Once that is done and the dehumidifier is operational, it requires relatively low maintenance. We recommend an annual check of the overall system and cleaning of the filters. Most professionals offer this service at reasonable rates.

So, how do you know if a crawl space dehumidifier is right for you? It starts by having your crawl space inspected and the moisture levels measured. If excessive moisture levels threaten your home, fight back by having the right dehumidifier professionally installed. You will avoid many costly future repairs and problems and sleep better at night, knowing your home is safe and dry. As always, we are here and happy to help.
