Why Crawl Space Insulation Still Matters In The Summer
Crawl space insulation still matters in the summer because it's going to protect your home against moisture damage, regulate humidity, limit heat transfer, and keep your energy bills more manageable.
With proper floor and wall insulation, the crawl space can become an extended conditioned room in your home and a duct-friendly zone, circulating cool, humidity-free air.

Homeowners Typically Think Insulation is Only Beneficial During Winter Months
It's common to believe insulation is only for fall or winter once the temperature drops, but summer humidity is actually a bigger threat to your home.
In the tri-state specifically, with heavy rains and humidity from the river valley, moisture builds up quickly in our homes and crawl spaces. Insulation is not only designed to lock in heat, but also to control temperature and reduce heat, manage humidity like preventing condensation, and protect air quality by limiting mold spores and smelly odors.
This is especially important since your crawl space is often the source of the air you breathe in the upper levels of your home! Since air rises and circulates through the air in your vents, it originates in your crawl space.
The Truth About Humid Summers and Your Crawl Space in the WV, OH, and KY Tri-State
- Clay Soil: This presents a unique problem as moisture is released slowly into the air, the clay holds water, and if you live in a valley or flood-prone area, your crawl space may be damp all summer, even if it hasn't rained recently!
- Older Homes: With a higher volume of older homes in our communities, we also have more homes with vented crawl spaces. Those vents enable the humid summer air to come right inside the crawl space and home. Your insulation has to work overtime to keep up and can fail faster without an encapsulation.
- Condensation: A lot of homes in our neck of the woods have condensation once the warm, humid air combines with the cooler crawl spaces. This leads to mold, wood rot, and breaks down the insulation entirely. Your traditional fiberglass or paper insulation is probably not cutting it.
A Better Solution Than Traditional Insulation For Your Home
Crawl Space Encapsulation with CleanSpace and SilverGlo Insulation
Alford Foundation & Crawl Space Repair works to make your crawl space as cool, dry, and energy-efficient as possible in the summer. Not only that, but it'll be warm in the winter.

We do this with the CleanSpace vapor barrier and sealing all air leaks from the outside. SilverGlo insulation paneling reduces moisture and humidity, contains inorganic materials so it doesn't support mold growth, and can contribute to lower energy bills. Instead of stuffing the joists with paper or fiberglass, this graphite-infused foam insulation is installed along the walls and can be added along the rim joists or along the crawl space floor for the most savings!
