Your crawl space can be damaged by water and any debris at some point. A wet crawl space is a major problem sign that there’s an issue – like excessive moisture – going on in your home’s crawl space. Once water invades the crawl space, it permeates the insulation. At Peak Structural, we can help with wet insulation.

What Causes Wet Crawl Space Insulation

Excess Moisture and Humidity

If your crawl space is not fully encapsulated, meaning that it is not sealed off from external elements like humidity and rain, then moisture will find its way inside. While some moisture in your crawl space is normal, excessive amounts can contribute to abnormal moisture and temperature levels in your home. More importantly, this moisture will quickly saturate the insulation in your crawl space, leading to a wet mess that doesn’t allow your insulation to function as it should. If you notice moisture in your crawl space, you should have the problem fixed before it affects your insulation.

Open to the Elements

As mentioned above, a crawl space that has not been properly encapsulated can greatly contribute to the water levels inside your crawl space. Heavy rain and even snowmelt can creep into your crawl space, causing a surplus of water and moisture. If you live in an area with periods of heavy snow – such as Denver – then snow can be blown into your crawl space, where it will then melt as the temperature warms up, producing moisture in the air that will start to seep into the insulation in your crawl space.


Mold is attracted to dark, damp spaces, so your crawl space is one of its favorite places to flourish. This is especially true when it comes to your crawl space insulation. Extremely susceptible to water, crawl space insulation can quickly become a new surface for mold spores to gather. So, if you are noticing mold in your crawl space, on your crawl space insulation, or elsewhere in your home, then you should first call a mold remediator. After that, contact a foundation repair professional to remove the wet, moldy insulation and replace it with insulation that is less absorbent.


The insulation in your crawl space can get wet due to a variety of reasons, including high humidity and moisture levels, exposure to the elements – especially rain and snow – and living in areas where flooding or heavy snowmelts take place. Choosing not to encapsulate your crawl space can also directly affect whether your crawl space gets flooded. A flooded crawl space can make the living areas of your home experience a change in the quality of their environment. So, if you want to protect your crawl space insulation from getting wet, encapsulation is the best solution for you.

If your insulation is wet, it is not something that you should simply ignore. This problem will not go away on its own and will worsen the longer it is left untreated. Because mold is attracted to dark, damp spaces, your home’s crawl space is the prime spot to facilitate its growth. Once mold starts to form in your crawl space, it has the potential to spread to other parts of your home, like your living room or bedroom. This aggravates asthma symptoms and allergies.

There are several factors as to why your crawl space insulation is a target for moisture. Your crawl space is meant to be a dry area, but due to its contact with the ground and exposure to the elements, it is common for flooding to occur. Also, insulation is an absorbent material, so it takes on and holds water with ease. Insulation that is more protected against moisture is available to prevent moisture from infiltrating the insulation.
