Insulation Company in Cerritos, CA
Blown in insulation is the most common retrofit job we perform in Cerritos, and it usually comes down to one problem: insulation that settled decades ago in homes built between the 1960s and 1990s. Cerritos’s planned tract developments went up fast, and many attics still hold original batts or loose fill that has compressed to a fraction of its rated R-value. The result is a house that fights itself in summer, when attic heat radiates through ceilings and forces the AC to run long cycles. We’re insulation-only contractors, not a general remodeler dabbling in one trade, so we diagnose exactly what’s happening above your ceilings and fix it with the right material, not whatever happens to be on the truck. Call (877) 680-3557 if you’d like us to look at your attic.
Why Cerritos Homes Are Different
Cerritos was built on dairy land after 1968, when the 605 and 91 freeways opened the area to rapid suburban development. That timeline matters for insulation. Most homes here are wood-frame tract builds from the 1970s through the 1990s with stucco exteriors, low-pitch or tile roofs, and attic assemblies that were insulated once, at construction, to the building codes of that era. Those codes called for far less insulation than today’s standards, and what went in has now been sitting in attics for thirty to fifty years. Fiberglass batts sag and lose loft. Loose fill compacts. The barrier degrades.
Because so many Cerritos neighborhoods came from the same developers in the same waves, the attic you have is often identical to the one three doors down. That’s an advantage. When a tech opens an attic in a 1980s planned unit development off South Street and finds four inches of settled cellulose, the same condition almost certainly exists across the block. The low-pitch tile roofs common here also make attic access predictable and repeatable, which means we can scope a job accurately and complete it without surprises.
Climate pushes the work in a specific direction too. Cerritos gets hot inland-influenced summers plus Santa Ana wind events that spike attic temperatures. Cooling loads, not heating loads, drive your energy bills. The practical priorities are attic radiant-heat management and ventilation, not just adding raw R-value. A dry climate also means blown-in fiberglass and cellulose hold their thermal performance well, but only if installed at proper depth and density.
Our Main Cerritos Services
Most Cerritos homeowners call us about two things: replacing or upgrading what’s in the attic, and sealing the thermal envelope with spray foam. Here’s what each job looks like in Cerritos.
Attic Insulation in Cerritos
Attic work in Cerritos almost always means removing or covering up settled insulation in a 1970s to 1990s tract home, not insulating new construction. Low-pitch tile roofs keep attic spaces tight, but our crews work in them regularly and know how to address ventilation alongside insulation depth. The goal is an attic that stops transferring summer heat into the living space below. We pull back or remove degraded material, air-seal the obvious bypasses, and install new insulation matched to your attic type and budget. See Attic Insulation in Cerritos for the full breakdown on materials and pricing.

Spray Foam Insulation in Cerritos
Spray foam serves a different purpose in Cerritos: air sealing. Older tract homes leak through top plates, can lights, and duct chases, and the Santa Ana winds find every one of those gaps. Closed-cell foam adds structural rigidity and a vapor barrier, useful in attics that double as storage or in floor assemblies over garages. Open-cell foam is often the better dollar-per-seal choice for attic rafters in this climate. We carry both Demilec and Icynene product lines, which means the decision is made by your house, not by our supplier. Read Spray Foam Insulation in Cerritos for the full detail.

Blown In Insulation in Cerritos

Blown in insulation in Cerritos is the fastest, most effective retrofit for attics in 1960s – 1990s tract homes where the original insulation has settled and compressed. Most Cerritos attics we open have four to six inches of material that once measured ten or twelve. Re-blowing to current recommended depth restores the thermal barrier without tearing out ceilings or disrupting living space, and in Cerritos’s dry, coastal-influenced climate, loose fill holds its performance for decades when installed at the right density. This is a core service for us, and you can read the full method and material options on our dedicated Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, settled, or dusty, and upstairs rooms run hot in summer even with the AC on full blast.
What it costs in Cerritos
Blown cellulose in a typical Cerritos attic runs $1,900 – $3,400 depending on square footage and whether old material gets removed first.
How we do it
We prep the attic, seal accessible bypasses, and blow GreenFiber cellulose to the density and depth that hits your target R-value without overloading the ceiling drywall.
Blown In Attic Insulation
Signs you need it
You can see the tops of ceiling joists in your attic, meaning less than six inches of loose fill remains between you and the roof deck.
What it costs in Cerritos
Blown-in attic insulation in Cerritos typically falls between $2,000 and $3,500 for a standard single-story tract home.
How we do it
We mask and protect the access point, run a hose to the attic, and blow insulation to a consistent depth with a calibrated machine while checking coverage across every bay.
Blown In Fiberglass Insulation
Signs you need it
Existing fiberglass batts are discolored, compressed, or shifted, leaving bare drywall patches and uneven temperature zones across the house.
What it costs in Cerritos
Blown-in fiberglass in Cerritos ranges from $1,800 to $3,200 for a typical attic, with the final number tied to depth and access.
How we do it
We remove or level the old material, then blow loose-fill fiberglass to a uniform height using guide markers so every section of the attic meets the same R-value.
Loose Fill Insulation
Signs you need it
Your attic has inconsistent coverage, with some bays full, others nearly empty, and you suspect settling after decades of Southern California heat cycles.
What it costs in Cerritos
Loose fill insulation jobs in Cerritos generally run $1,800 – $3,000 depending on the material chosen and the attic’s square footage.
How we do it
We choose between cellulose and fiberglass based on your attic’s condition and your priorities, then blow the material to a consistent depth with attention to soffit ventilation so airflow stays intact.

Is blown in insulation worth it for a Cerritos home built in the 1980s?
Yes. A 1980s tract home typically has R-19 or less in the attic. Bringing it to current recommended levels cuts cooling load meaningfully in Cerritos summers. Call (877) 680-3557 for a specific assessment.
How long does blown in insulation take in Cerritos?
Most Cerritos attics take one day, including prep, air sealing of obvious bypasses, and blowing to full depth. Larger or two-story homes can take a day and a half. Call (877) 680-3557 to schedule a look.

What Cerritos Customers Say
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Miguel Flores"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."
— Nia Robinson"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Mark Schaefer
