Insulation Company in Cerritos, CA
Blown in insulation solves the most common comfort problem we see in Cerritos: original 1960s and 1970s attic insulation that has settled to half its intended depth. Most Cerritos homes were built as part of a master-planned development wave, which means block after block of wood-frame tract homes with the same attic configuration and the same weak point at the top of the house. When attic temperatures climb past 140°F in July, that tired insulation can’t stop heat from pressing down into living spaces. We’re Comfort Zone Insulation Co, an insulation-only specialist serving Cerritos since 2012, and we carry eight leading brands so the material we install is the one your home actually needs.

Why Cerritos Homes Are Different
Cerritos is a master-planned city developed largely in the 1960s and 1970s, and that single fact shapes nearly every insulation job we do here. The original construction was consistent: wood-frame tract homes with stucco exteriors, standard ceiling joist spacing, and loose-fill or fiberglass batts laid to the code minimums of that era. Fifty or sixty years later, those minimums don’t hold up. Original attic insulation in many Cerritos homes has settled or compressed to R-11 or less, roughly a third of what current energy standards recommend for Southern California attics.
The climate compounds the problem. Cerritos sits in an inland coastal zone with warm, dry summers and mild winters. What that means for homeowners is that the attic is where the house wins or loses its cooling battle. An uninsulated or under-insulated attic can exceed 140°F on a hot afternoon, and that heat doesn’t stay politely in the attic. It radiates down through the ceiling, pushes the air conditioner to run longer cycles, and leaves second-floor rooms or rooms at the back of the house five to ten degrees warmer than the thermostat setting. We see this pattern constantly in Cerritos, especially in resale homes where a new owner discovers the problem only when the first summer electric bill arrives.
Our Main Cerritos Services
Cerritos homeowners call us most often about two things: attics that are bleeding cool air all summer, and rooms that never seem to reach the temperature on the thermostat. Both usually trace back to insulation that was under-specified when the home was built.
Attic Insulation in Cerritos
The attic is the single highest-impact insulation zone in most Cerritos homes. When original loose-fill has settled to a thin layer over the ceiling drywall, you’re paying to air-condition a space you don’t live in. We treat attic work as its own dedicated service, starting with an assessment of what’s actually up there now, then air-sealing the bypasses that let conditioned air escape from the living space into the attic before adding new insulation to the correct depth. For a full breakdown of how attic work goes in Cerritos, see our Attic Insulation in Cerritos page.
Spray Foam Insulation in Cerritos
For Cerritos homes where air leakage is as much of a problem as low R-value, spray foam does double duty: it insulates and air-seals in one application. That’s useful in older tract homes where the original construction left gaps around plumbing chases, recessed light fixtures, and top plates. We install Icynene and Demilec open- and closed-cell systems, chosen based on the specific cavity and the performance goal. Details on when spray foam is the right call are on our Spray Foam Insulation in Cerritos page.

Blown In Insulation in Cerritos
Blown in insulation is our most-requested service in Cerritos because it’s the most direct fix for the settled-attic problem that defines this city’s housing stock. We blow loose-fill material across the attic floor to a uniform depth that restores the R-value your ceiling actually needs, covering every joist bay and odd corner without tearing open walls. For Cerritos homes built in the 1960s and 1970s, this single upgrade is often the difference between an AC that cycles off at 4 p.m. and one that runs until midnight. Learn more about the full scope of this work on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Rooms directly under the attic stay warm long after sundown in summer and the existing attic insulation looks thin, patchy, or settled well below the joist tops.
What it costs in Cerritos
Blown-in cellulose in Cerritos typically runs $1.35 – $2.60 per square foot installed, depending on the target R-value and how much old material needs to be removed first.
How we do it
We remove or level any compromised existing material, air-seal the ceiling penetrations that leak conditioned air, then blow GreenFiber cellulose to a consistent depth that achieves your specified R-value.
Blown In Attic Insulation
Signs you need it
Your attic has bare patches, your upstairs feels hotter than downstairs by mid-afternoon, or you can see the tops of the ceiling joists because the insulation has compressed.
What it costs in Cerritos
Blown-in attic insulation in Cerritos typically runs $1.35 – $2.60 per square foot installed, with total project cost shaped by attic square footage and access conditions.
How we do it
We set an intake hose from the truck to the attic, direct the blowing machine to distribute loose-fill evenly across the floor, and build depth progressively until we reach the R-value agreed on beforehand.
What Blown In Insulation Costs in Cerritos
| Item | Typical range in Cerritos |
|---|---|
| Blown-in cellulose (per sq ft installed) | $1.35 – $2.60 |
| Blown-in fiberglass (per sq ft installed) | $1.20 – $2.40 |
| Existing insulation removal (per sq ft) | $0.75 – $1.75 |
How long does blown in insulation take in Cerritos?
Most Cerritos attics are fully insulated in one working day, typically three to six hours depending on square footage and whether old material needs removal first. Call (855) 341-7856 for a project-specific timeline and free estimate.
Can you add blown in insulation over my old insulation?
In many Cerritos homes, yes. If the existing material is dry, free of rodent activity, and not compressed past usefulness, we can blow new material directly over it to reach the target R-value without removal. We confirm this during the on-site assessment rather than assuming it from a phone call.

We install and service blown-in products from Owens Corning, Johns Manville, Knauf, and Rockwool, among the eight manufacturer lines we’re authorized to install. Our Cerritos crews stock common loose-fill and batt materials locally, so most jobs start within the week. See the full portfolio on our brands page.

What Cerritos Customers Say
"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."
— Dustin Sullivan"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Marco Morales"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
