Crawl Space Insulation
Crawl Space Insulation: Keep Cold Floors Out and Comfort In
If your floors feel cold in the winter or your energy bills keep climbing, your crawl space may be to blame. Without proper insulation, air moves freely under your home, bringing in cold drafts, trapping moisture, and putting extra strain on your heating and cooling systems.
At Force Basements, we install high-performance crawl space insulation that fits your home’s exact needs. Whether your space is vented or fully encapsulated, we use the right materials and methods to keep conditioned air inside and damaging moisture out.
How Force Basements Installs Crawl Space Insulation
Every home and crawl space is unique — that’s why our crawl space insulation process is customized to your space, building type, and existing conditions.
1. Inspection & Assessment
We examine your crawl space for existing insulation, moisture issues, airflow, and potential structural concerns. We also identify whether the space is vented or enclosed.
2. Prep & Moisture Control

4. Install & Seal
We insulate walls, rim joists, and sometimes floors above the crawl space (depending on design), sealing gaps to reduce drafts and heat loss.
5. Optional Upgrades
If desired, we can complete your crawl space with:
