Attic insulation installation by 101 Exterminators in Central California

New Insulation for Energy Efficiency and Pest Resistance

Blown-In Cellulose · Fiberglass Batt · Attic & Crawl Space

After insulation removal or when installing fresh insulation in an uninsulated or under-insulated space, proper installation restores thermal performance and can incorporate pest-resistant products. 101 Exterminators installs blown-in cellulose and fiberglass, as well as batt insulation for crawl space floor installations. We coordinate insulation work with any necessary pest exclusion or vapor barrier installation to ensure the completed result is both thermally effective and pest-resistant.

Why This Matters Here

California Title 24 energy standards require minimum R-values that many older homes in Monterey, Salinas, and Hollister do not currently meet. Upgrading insulation in these properties reduces energy costs and meets current standards. Borate-treated cellulose insulation (such as Cocoon or similar products) provides inherent pest resistance, making it an excellent choice for attics in termite-active areas.

Blown-in cellulose or fiberglass installation to achieve target R-value (typically R-38 to R-60 for California attics). Crawl space joist bay fiberglass batt installation for under-floor insulation. We work to California Title 24 standards and can provide documentation for permit purposes when required.

Signs You Need This Service

  • Attic insulation below R-19 or compressed to less than 4 inches — significant energy loss
  • Recent insulation removal that needs replacement
  • Home failing energy audit or experiencing higher-than-expected heating/cooling costs
  • Crawl space floor insulation missing or falling from between joists

Our Process

Every service follows a structured protocol designed to deliver effective, lasting results — not a temporary fix.

01
Step 01

Existing Conditions Assessment

We measure current insulation depth, note any areas requiring air sealing before installation, and confirm that the attic is rodent-free before new insulation goes in.

02
Step 02

Air Sealing (As Needed)

Gaps around recessed lights, plumbing penetrations, HVAC ductwork, and top plates are sealed before insulation is blown in to maximize thermal performance.

03
Step 03

Insulation Installation

Machine-blown cellulose or fiberglass is distributed to uniform depth and density across the attic floor or specified area. Depth gauges are placed and photographed for documentation.

04
Step 04

R-Value Confirmation

Installed depth is documented and final R-value confirmed. For permit applications, we provide the necessary documentation of materials and installation specs.

Frequently Asked Questions

What R-value do I need for my California attic?

California Title 24 requires R-38 minimum for new construction in most climate zones. For existing homes in Monterey and Santa Cruz counties (Climate Zone 3), upgrading to R-38 or R-49 is recommended. For inland areas like Hollister and South Santa Clara County (Climate Zone 5), R-49 or higher maximizes energy savings due to larger temperature swings.
