Crawl Space Insulation, Cleaning & Rodent Protection

For this project, we focused on improving energy efficiency, cleanliness, and pest prevention in the crawl space. We began by installing new insulation in the rim joist area and over all vents. The insulation was carefully sealed around the edges with spray foam to create an airtight barrier, helping reduce drafts and energy loss.

To prevent rodent entry, wire mesh was installed over any gaps or openings, including between the crawl space and the slab on grade, as well as inside all vents. These areas were then insulated with rigid foam for extra protection.

Next, we sprayed all concrete surfaces with a germicide to neutralize rodent urine and improve overall sanitation. The heating ducts and sewer lines were wiped down, spider webs and loose debris were removed, and stored items were cleared out. Finally, a HEPA vacuum was used on the crawl space floor to safely remove rodent droppings and leave the area clean.

The result is a crawl space that is cleaner, healthier, and better protected against pests while improving the home’s comfort and efficiency.
