Why Crawl Space Ventilation Is The Key To Keeping Your Home Safe And Dry

Share this article

Your crawl space may be great for storing that old box of Halloween decorations you can’t fit into your garage. But, they are notorious for leading to health issues as well as causing your home to have poor air quality. Learn how crawl space ventilation can keep your crawl space nice and dry, and how WAVE Home Solutions can ventilate your crawl space as well as improve the overall air quality of your home.

Why Crawl Space Moisture Is So Bad For Your Home And Health

Crawl space moisture can lead to mold and wood rot, both of which can cause structural damage to your home.

Crawl space moisture can also cause a plethora of health problems because of the impact it has on your home’s air quality. This moisture breeds mold, odor, toxic vapors, allergens, and radon. If not corrected, this poor air, along with the contaminants it breeds, makes its way upstairs to your living area.

Radon is a major source of poor air quality in homes because it is comes from the soil beneath your house and seeps into your crawl space, and it eventually travels up to your living area. It can lead to several health problems, including:

  • Coughing and wheezing
  • Coughing up blood
  • Chest pain
  • Shortness of breath
  • Hoarseness
  • Bronchitis
  • Pneumonia

What About Using A Crawl Space Dehumidifier?

Crawl space dehumidifiers can help with localized moisture, but they aren’t a solution for keeping your crawl space dry. This is because they don’t provide any actual ventilation. Crawl space dehumidifiers basically just recirculate the same unhealthy air throughout the area. They also don’t improve the air quality of your home because they can’t expel harmful gases or pollutants. They are pretty expensive to run as well and can cost you anywhere between $60 to $90 a month.

What About Crawl Space Encapsulation?

Crawl space encapsulation is a great first step to removing moisture in your crawl space, but it won’t keep your home moisture free or help with any moisture that’s already saturated in your floor beams.

When you encapsulate your crawl space, you install a vapor barrier on the crawl space floor that continues up to the foundation wall and covers the floor and posts.

It’s great for creating an environment that can be controlled for moisture because it helps keep outside moisture from coming in, but it doesn’t actually keep the moisture from developing inside the crawl space. Crawl space encapsulation doesn’t create the necessary air exchanges that expel and control moisture. It also doesn’t protect your home from air contaminants, like carbon monoxide and other dangerous gases. That’s where crawl space ventilation comes into play.

Crawl Space Ventilation

To really keep your crawl space nice and dry, you need to start with the source and install a ventilation system.

A crawl space ventilation system will do some very important things that encapsulation and a dehumidifier just can’t:

  • Expel moisture, odors, stagnant air, radon, toxic vapors and indoor pollutants so they can’t travel upstairs and impact your health.
  • Replenish the air of your crawl space with an equal amount of warmer, drier, fresher air.  
  • Ventilate the crawl space by increasing circulation for moisture extraction from your home’s walls, floors and beams, which reduces mold, odors, insects, and dust mites.
  • Improve the overall air quality of your whole home by reversing the natural air flow and creating air exchanges so the poor air doesn’t enter your living area.

The Department of Energy Swears By The Effectiveness Of Crawl Space Ventilation

The Department of Energy conducted a test that proved the effectiveness of crawl space mechanical ventilation by monitoring 12 identical homes. They compared crawl spaces with foundation wall vents to closed crawl spaces without foundation vents that utilized mechanical ventilation. Their findings show that at the end of the day, if you want to keep your crawl space dry, mechanical ventilation is the key. Plus, crawl space ventilation can lower your energy costs by 17%.

How WAVE Home Solutions Can Help

The WAVE Multi-Sensor Crawl Space & Booster Fan Unit will keep your crawl space dry by creating whole house air exchanges that will improve the overall air quality of your home. Our WAVE Multi-Sensor Crawl Space & Booster Fan Unit will also continuously expel harmful gases, including radon and carbon monoxide.

This maintenance-free unit is also compatible with the myHome App, which allows you to monitor your home 24/7, 365 days a year for carbon monoxide. If the WAVE unit’s monitor detects high levels of carbon monoxide, you will get an alert via the myHome app, and then the WAVE unit will automatically increase its ventilation rate to expel the carbon monoxide regardless of the level of moisture in your crawl space.

The myHome app also allows you to:

  • Receive real time data on the relative humidity and the temperature outdoors and in your crawl space and/or basement
  • View and change the current settings on your WAVE unit right from your smartphone.
