Insulation Installation in San Francisco, CA
101 Exterminators offers attic and under-floor insulation installation in San Francisco under SPCB Lic. #9119. The correct material and target depend on the accessible cavity, existing insulation and applicable requirements. Rodent entry or moisture should be addressed before new material goes in.
Warning Signs
When to Ask About Insulation Installation in San Francisco
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.
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
How It Works
What to Expect from Insulation Installation in San Francisco
Tell us which area needs insulation and whether pests or moisture have affected it. Those conditions should be checked before installation.
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.
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.
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.
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.

Common Questions
Insulation Installation FAQs for San Francisco
My Edwardian flat has almost no attic. Where could insulation go?
The available roof and floor cavities decide. An attic may be too shallow for the proposed material, while a floor over a garage or sub-area may be accessible. Ask for measurements and a plan specific to the flat.
Is insulation worth doing in San Francisco when winters are mild?
It may be. The value depends on existing insulation, available space and comfort or energy goals. Ask for an assessment rather than assuming San Francisco weather makes the work unnecessary.
Can new insulation go in before the rodent work is finished?
New insulation should follow assessment of any active rodent entry. Ask whether exclusion and trapping are separate work and when the space can be checked before installation.
