Do Dehumidifiers Work In Crawl Spaces?

Crawl Space Dehumidifier

For the best living conditions, it is important that you know how air moves in your home. Air will be drawn upwards from lower levels and may include mold spores or moisture. Ventilation helps draw fresh air into an area as required.

This type of air movement or airflow is known as "the stack effect." This means most homes have half their air coming from crawl spaces. As a result, your crawl space needs to be as mold free as possible. It also needs to be as dry as possible.

This is why we use crawl space dehumidifiers.

Reasons to Use a Dehumidifier in Your Crawl Space

If you live in a humid climate or your home lacks ventilation, using the best crawl space dehumidifier is one of the best investments you can make.

Protect Health

Did you know that air in your crawl space has a direct impact on the health of your family? To protect their well-being, we recommend installing a dehumidifier. High humidity levels can encourage mold and dust mites which may lead to allergies like headaches, eye irritation or respiratory problems.

To avoid these symptoms, install a high quality crawl space dehumidifier.

Protection from Pests

A dehumidifier is the perfect tool to manage moisture in your home, not only for the protection of you and your family but also because it helps keep pests away. Rodents are attracted by water, so they often live in crawl spaces. Dehumidifiers can help reduce pest invasions while controlling excess humidity levels at the same time.

Improve Structural Integrity

When the humidity level in your crawl space is over 70%, it can cause condensation. Condensation will make wood more prone to rotting, which means it won’t be able to support all the weight above it.

If significant timber rotting occurs, then any load bearing structures are likely to fail.

When high levels of humidity have been detected by a humidistat in your crawlspace or basement, there's an increased chance for water droplets coming into contact with wooden supports.

This leads to damp and will produce mold growth, weaking wood.

Increased Comfort

The home should be comfortable. One of the issues with high humidity in a house is that it can make household members feel sticky, hot, and clammy. A dehumidifier will allow your air conditioning to work less hard. This makes maintaining a comfortable temperature easier.

Save Energy

Humidity can be a costly problem for those living in humid climates. Air conditioners must work harder, which means expensive energy bills.

A dehumidifier will help reduce humidity levels, which means your AC unit won’t have to work as hard, to keep your home cool.

This means a more comfortable home and lower power bills.

Final Verdict

Dehumidifiers work very well in crawl spaces. We recommend that every homeowner with a crawl space underneath their house should buy a dehumidifier.

This will provide many benefits for your home and family including increased comfort and lower running costs.
