The foundation of your home’s well-being begins in your crawl space.

What are the signs of wet insulation and what does it mean for your home? Mount Valley Foundation Services is here to explain symptoms and provide a long-lasting solution.
Getting to the Bottom of the Problem: Wet Insulation
Insulation in your crawl space serves an essential function in sustaining a dry and wholesome atmosphere. However, when traditional insulation gets wet, it stops functioning effectively, leading to other problems, including greater energy use, structural damage, and compromised indoor air quality.
Signs of Moisture in Your Insulation
Unusual signs in your home often serve as red flags for lurking moisture issues. Here are some key indicators you should keep an eye out for:

- Moist or saturated insulation material: When the insulation in your crawl space feels wet or soggy, it’s a surefire signal of a moisture concern.
- Pungent odor of mold or mildew: A telltale earthy smell often points to mold or mildew, both thrive in moist surroundings.
- Cold floors: Damp insulation can bring down your home’s energy efficiency, causing you to feel cold floors in the winter or an overburdened air conditioner in the summer.
- Visible signs of mold or pests: Damp insulation can create a conducive environment for mold and pests, which can become apparent over time.
- Drooping insulation: Absorption of water makes insulation heavier, resulting in drooping or detachment from the walls or ceiling.
Primary Causes of Wet Insulation
Identifying the causes of damp crawl space insulation can help in finding the right solution. The primary culprits often are:
- Poor drainage: If your property’s drainage is poor or if the gutter and downspout system is faulty, rainwater can accumulate around your foundation and seep into your crawl space.
- Excessive humidity: The typically hot and humid climate of South Carolina and Western North Carolina can lead to crawl space condensation, resulting in damp insulation.
- Leaks in plumbing: Damp insulation can also be a result of leaks from plumbing lines traversing through your crawl space.
- Inadequate vapor barrier: Without an effective vapor barrier, moisture from the ground can evaporate into your crawl space, leading to damp insulation.
