Pure Eco installs blown-in insulation throughout Long Beach using professional-grade equipment and materials rated for California Climate Zones 6 and 8.
Blown-in insulation is the most practical and effective solution for most Long Beach attics. It installs faster than batts, fills irregular framing and tight spaces better, settles to a more uniform coverage, and is the standard method for topping up existing insulation without a full removal project. For Long Beach homes spanning a century of different construction eras, blown-in handles the variety of attic geometries better than any other product. Achieving a truly seamless thermal blanket requires both specialized equipment and a contractor committed to the highest industry standards.
As a licensed contractor (Lic #993589), we provide a 100% satisfaction guarantee on every installation. We offer free consultations and clear estimates before any work begins, ensuring you get honest advice with no pushy sales tactics. Our experienced local technicians focus on fast, professional results that prioritize your air quality and long-term energy savings.

Long Beach attics are not uniform. The early 20th-century bungalows in Bixby Knolls and California Heights have low-slope roof sections and tight eave runs that make batt installation difficult or impossible to do correctly. The postwar homes throughout Wrigley and Midtown have non-standard joist spacing and obstructions from HVAC equipment and electrical runs. The 1960s and 1970s tract homes in East Long Beach have more standardized framing but often have existing insulation that has settled unevenly and needs to be supplemented rather than replaced.
Blown-in insulation handles all of these conditions. The loose-fill material is conveyed through a hose and deposited in place, flowing around obstructions and filling irregular cavities to a uniform depth.

Long Beach is in California Title 24 Climate Zones 6 and 8, which requires a minimum attic insulation R-value of R-38 for existing homes and recommends R-49 as the performance target. Most Long Beach homes built before 1980 fall below that range. Blown-in insulation is the most efficient method for closing the gap, whether installed over existing material or as a full replacement after removal.
Material selection matters more in Long Beach than in inland cities. The persistent marine-layer humidity means blown-in fiberglass is often the better choice than cellulose for Long Beach attics, particularly in homes near the coast, where ambient humidity is consistently elevated. Fiberglass does not absorb moisture the way cellulose can, making it more stable in the Long Beach climate over the long term.
The City of Long Beach operates its own independent building department. Blown-in insulation projects that are part of a larger renovation may trigger permit requirements. The Long Beach building department can confirm current thresholds for your specific project.

A typical blown-in insulation installation in a standard Long Beach home takes three to six hours. The blower unit stays outside or in the truck, with only the hose and installer entering the attic. Living areas are not affected. When installation is complete, we remove all equipment, clean up any material near the access point, and walk you through the completed installation.
Scheduling attic cleaning before blown-in insulation installation ensures the space is free of contaminants, allowing the process to proceed efficiently without delays.
California Title 24 sets R-38 as the minimum for existing homes in Climate Zone 8 and R-49 as the recommended target. Even in Long Beach’s mild coastal climate, reaching R-49 delivers meaningful energy savings and comfort improvement.
Yes, blown-in insulation can be added over existing fiberglass, provided the batts are in acceptable condition. There should be no pest contamination, no moisture damage, and no significant mold. Blown-in insulation can be installed directly over intact existing batts.
All blown-in products settle somewhat in the first few months after installation. We account for this by installing to a depth above the target R-value. The final settled depth delivers the rated performance.
For homes near the coast where humidity is consistently elevated, we typically specify fiberglass because it does not absorb moisture. For homes further inland in East Long Beach, where humidity is less of a factor, cellulose is also a good option.
No, blown-in insulation will not block attic vents. We install baffles at eave vents to maintain the ventilation channel and verify that all attic ventilation pathways are unobstructed after installation. Proper ventilation is especially important in the Long Beach humidity environment.
