Premium Crawl Space Wall & Floor Insulation
A well-insulated crawl space can completely change how your home feels. Cold floors warm up, damp odors disappear, and energy bills start to level out. To get those results, the installation has to be done the right way, and that’s where our team comes in.
At Larson Home Services, we follow a proven process that ensures your crawl space is sealed, insulated, and ready to protect your home for years to come.
We begin with a full inspection to identify drafts, damp areas, or failing insulation.
Before new insulation is added, we use trusted air sealing methods to close cracks and leaks that allow air and moisture to sneak in.
Based on your crawl space and goals, we add insulation along walls or floors to create a durable thermal barrier. This step connects with our broader insulation services, so your entire home performs better.
After installation, we double-check every detail to make sure your crawl space is sealed, dry, and energy-efficient.
For many homeowners, the process begins with a home energy consultation. This assessment highlights where your home is losing energy and shows how crawl space insulation can deliver the greatest improvements in comfort and efficiency.
Benefits of Crawl Space Insulation
Insulating your crawl space isn’t just about what happens below the surface. The improvements show up throughout your home, from the air you breathe, the comfort you feel, and even in your utility bills.
Prevents Moisture
An unprotected crawl space often acts like a sponge, pulling dampness in from the ground. That excess moisture can lead to mold, mildew, and wood rot that weaken your home’s structure. Adding insulation helps keep the area dry and stable, protecting both your crawl space and your foundation.
Improves Indoor Air Quality
Air naturally rises, which means whatever is in your crawl space eventually makes its way upstairs. If that air is musty, humid, or filled with allergens, your family breathes it in daily. A sealed and insulated crawl space keeps pollutants out, so the air circulating in your home is cleaner and healthier.
Pest Prevention
Crawl spaces are a favorite hiding place for rodents and insects, especially if they’re damp or easy to access. Proper insulation closes off the small openings pests use to get inside, while also creating an environment that’s less appealing for them to settle in.
Improved Home Comfort
Cold winter floors, sticky summer humidity, and uneven room temperatures often trace back to the crawl space. Insulating it helps balance your home’s climate, so your living spaces stay consistently comfortable year-round.
Energy Savings
When your crawl space is leaking air, your heating and cooling systems have to work harder to keep up. According to ENERGY STAR, sealing and insulating this part of the home reduces wasted energy and lowers monthly utility bills. Over time, those savings add up, turning crawl space insulation into one of the smartest investments you can make in your home.
Types of Crawl Space Insulation
An unprotected crawl space often acts like a sponge, pulling dampness in from the ground. That excess moisture can lead to mold, mildew, and wood rot that weaken your home’s structure. Adding insulation helps keep the area dry and stable, protecting both your crawl space and your foundation.
Spray Foam Insulation
If you want insulation that truly locks down your crawl space, spray foam insulation is hard to beat. Once applied, it expands into every little gap and crack, sealing out moisture, drafts, and even pests. Because it offers one of the highest insulation values available, spray foam is especially effective in the cold winters and humid summers we see across Wisconsin and Minnesota.
It’s a long-term solution for homeowners who want dependable comfort and energy savings.
Batt Insulation
Batt insulation is the option many people are most familiar with. Made from fiberglass and fitted between joists, it’s a straightforward way to add thermal resistance in crawl spaces that are dry and easy to access.
While it’s an affordable choice, it doesn’t provide the same level of air sealing or moisture protection as other methods. Still, for certain crawl spaces, it can be a practical way to improve comfort without stretching the budget.
Foam Board Insulation
Foam board insulation, also known as rigid foam, gives crawl spaces a durable layer of protection. Installed directly along crawl space walls, these panels create a solid barrier against temperature swings and damp conditions.
When paired with proper sealing, foam board helps maintain steady indoor temperatures and prevents drafts from creeping up into your living spaces. It’s a smart, durable option that holds up well over time.
