Crawl Space Insulation in Meridian, Idaho
Protect Your Home from the Ground Up
When most people think about insulation, they picture attics and walls, but your crawl space plays a major role in your home’s comfort and energy efficiency. At Marv’s Insulation, we specialize in professional crawl space insulation services for homes across Meridian and the Treasure Valley. Whether you’re building new or upgrading an older home, we’ll help you create a healthier, more efficient living space from the ground up.
Why Insulate Your Crawl Space?
A poorly insulated crawl space can lead to cold floors, high energy bills, and even moisture damage. Here’s how proper insulation makes a difference:
- Lower Energy Bills – Prevent heat loss through the floor and reduce HVAC strain
- Improved Comfort – Keep floors warmer in winter and cooler in summer
- Moisture Control – Reduce the risk of mold, mildew, and wood rot
- Radon & Pest Protection – Seal out harmful gases and unwanted critters
- Better Air Quality – Stop musty odors and allergens from entering your home
Did you know? Up to 40% of the air you breathe on the first floor comes from your crawl space.
What Type of Crawl Space Do You Have?
Understanding your crawl space helps determine the best insulation approach:
- Vented Crawl Spaces – Allow outside air to circulate; more prone to moisture issues
- Unvented (Sealed) Crawl Spaces – Fully enclosed and better for energy efficiency and moisture control
We’ll evaluate your space and recommend the right solution for your home and budget.
Best Insulation for Crawl Spaces
Not all insulation is created equal, especially when it comes to damp, enclosed areas like crawl spaces. We install:
Spray Foam Insulation
- Expands to seal gaps and cracks
- High R-value and moisture resistance
- Ideal for sealing around pipes, ducts, and joists
Rigid Foam Board Insulation
- Durable and moisture-resistant
- Great for crawl space walls and underfloor applications
- Helps prevent thermal bridging and heat loss
We avoid fiberglass in crawl spaces—it absorbs moisture and can lead to mold growth.
