Insulation Company in Bellflower, CA
Blown in insulation is the fastest way to bring a 1950s Bellflower tract home up to modern thermal performance without tearing out drywall. Most of the single-story stucco houses in 90706 and 90707 were built when R-11 batts were considered plenty, and decades of compression plus air leaks mean those attics now behave more like ovens than insulators. We match the material to the job, not the job to whatever we have on the truck, and for Bellflower’s aging housing stock that usually means dense-packed cellulose or blown fiberglass in the attic.

Why Bellflower Homes Are Different
Bellflower’s housing stock is dominated by single-story, wood-frame tract homes built between the 1950s and 1970s with stucco exteriors. These homes were constructed before California’s Title 24 energy standards existed, which means the original insulation was often thin fiberglass batts or, in some cases, newspaper-based material that has since settled into a layer about as effective as cardboard. Attics in the older tracts near the 91 Freeway routinely exceed 140°F in summer, and that heat doesn’t stay in the attic. It radiates down through ceilings, forces your AC to run longer, and drives up Southern California Edison bills month after month.
The LA Basin climate shapes the work too. Bellflower gets hot, dry summers where the temperature difference between your attic and living space can hit 50 degrees by mid-afternoon. Mild winters mean heating bills are less of a concern, but summer cooling loads are brutal. Homes here need insulation that performs in a specific way: strong resistance to radiant heat gain, good air-sealing capability, and enough density to prevent thermal bypass around recessed lights, plumbing penetrations, and the dozens of gaps common in 60-year-old framing. Original fiberglass batts in Bellflower walls are often compressed, dirty, and separated from the drywall, which is why blown in cellulose and blown fiberglass are such effective retrofits here – they conform to irregular cavities instead of leaving gaps.
Our Main Bellflower Services
Bellflower homeowners call us most often about two things: attics that turn their homes into saunas and walls that leak conditioned air. Both services address the same root problem, just from different angles.
Attic Insulation in Bellflower
Most Bellflower attics have original fiberglass batts that have lost most of their R-value through decades of compression, rodent traffic, and moisture exposure. We remove the old material, air-seal the gaps around top plates and penetrations, and install new insulation matched to your attic’s specific conditions. In Bellflower’s hot summers, that often means a radiant barrier facing plus dense blown fiberglass or cellulose. Attic Insulation in Bellflower is the single highest-impact upgrade for older tract homes in 90706 and 90707.

Spray Foam Insulation in Bellflower
Some Bellflower homes have cathedral ceilings, converted garages, or kneewall spaces where blown material won’t stay in place or batts can’t fit properly. That’s where spray foam becomes the right tool. Open-cell Icynene works well for interior cavity filling and sound dampening, while closed-cell Demilec gives you a vapor barrier plus higher R-value per inch for areas with moisture concerns. We’ll walk you through which foam chemistry fits your specific Bellflower home. Spray Foam Insulation in Bellflower is worth considering if your home has odd-shaped framing or you want air-sealing and insulation in one step.

Blown In Insulation in Bellflower
Blown in insulation is the most practical retrofit for Bellflower’s 1950s and 1960s tract homes because it reaches places rolls and batts can’t: wall cavities with no insulation at all, irregular joist bays, and attics full of wiring and framing. Dense-packed cellulose through GreenFiber or blown fiberglass settles into every gap, restoring the thermal barrier these homes never really had. In Bellflower’s 140°F summer attics, that’s the difference between an AC that cycles normally and one that runs from noon to midnight. Most Bellflower jobs finish in a single day. Blown In Insulation is the workhorse retrofit for this city’s housing stock.

Blown cellulose for a typical Bellflower attic runs $1,200 to $2,800 depending on square footage and the R-value target.
How we do it
We remove or level existing material, air-seal penetrations, then dense-pack GreenFiber cellulose to the R-value your attic depth allows.

How long does blown in insulation last in a Bellflower attic?

What Bellflower Customers Say
"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Gilbert Ramirez"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Veronica Guzman"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Rachel Sullivan
