Insulation Company in Cerritos, CA
Blown in insulation is the most common retrofit we handle in Cerritos, and it usually pays for itself faster here than almost anywhere else in the LA Basin. The city’s 1960s through 1980s tract homes were built with thin R-11 attic batts that have settled, compressed, and stopped doing their job. Add Cerritos’ inland heat and strong afternoon sun, and you get upstairs bedrooms that run 10 to 15 degrees warmer than the living room every July. We match the material to your home, not the other way around. Call (833) 390-3099 for a free attic assessment.
Why Cerritos Homes Are Different
Cerritos is a master-planned, fully built-out city. That sounds like planning trivia, but it changes the insulation work we do. There is almost no new construction here. Nearly every job is a retrofit or replacement inside an existing postwar or 1960s through 1980s tract home, mostly the single-story ranches and two-story plans that define the ABC-area developments north and south of Artesia Boulevard. Those homes were built for a different energy era. Original attic insulation is typically R-11 fiberglass batt, and after 40 or 50 years it is compressed, settled, and in too many cases contaminated by decades of rodent activity.
The climate adds another layer. Cerritos sits just inland enough to escape the coastal marine layer, so summers are hot and dry with strong afternoon sun, and Santa Ana heat events push attic temperatures well past 140 degrees. That makes cooling-load reduction the real insulation value here, which is exactly why high-R attic insulation and air-sealing matter more than heavy wall insulation in this climate. We also deal with Cerritos’ strict, proactive code enforcement and HOA-heavy tracts. Title 24 compliance and proper permit-pulling are a defining part of doing insulation work here, more than in the neighboring unincorporated pockets. Fountain Valley Insulation has served Cerritos since 2014, and we know which permits apply to which tract and when the inspector needs to see the attic access and ventilation.
Our Main Cerritos Services
Most Cerritos homeowners call us about two things: attic insulation replacement and spray foam for hard-to-condition spaces. Here is what each job looks like in this city.
Attic Insulation in Cerritos
In Cerritos tract homes, attic insulation is almost always a removal-and-replacement job rather than a simple top-off. The original builder-grade batts have usually settled below the top plates and lost most of their R-value. We pull the old material, air-seal the penetrations, and blow in fresh R-38 to R-49 insulation. Detailed costs and the full scope for Cerritos attics are on our Attic Insulation in Cerritos page.
Spray Foam Insulation in Cerritos
Spray foam earns its keep in Cerritos homes where an attic conversion, bonus room, or knee wall is leaking conditioned air. Because Cerritos is fully built out, many homeowners add living space by converting garages or enclosed patios, and those spaces almost never have adequate insulation. Closed-cell foam seals those cavities and adds structural strength at the same time. See what spray foam costs and how it performs in this climate on our Spray Foam Insulation in Cerritos page.

Blown In Insulation in Cerritos
Blown in insulation in Cerritos is the highest-impact upgrade for most of these older tract homes. The housing stock here dates mainly from the 1960s through the 1980s, when builders put in the minimum R-11 attic batts and moved on. After decades of heat, settling, and the occasional rodent, that material is compacted and underperforming. Blowing in fresh R-38 to R-49 insulation over an air-sealed attic floor is the single most effective way to cut cooling costs in Cerritos’ inland heat. We install both fiberglass and cellulose blown-in material depending on the attic condition and your goals. Learn more about the full range on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic batts are compressed below the top plates, you want a denser, quieter material, or you prefer a high recycled-content product that settles into tight corners.
What it costs in Cerritos
Cellulose insulation in Cerritos attics typically runs $1.20 to $2.00 per square foot installed for a standard R-38 upgrade.
How we do it
We remove old contaminated material, air-seal penetrations, then dense-pack or loose-fill the cellulose to the target R-valve with a calibrated blower.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms run noticeably hotter than downstairs in summer, your attic batts are visibly flattened or uneven, or your cooling bills climb every August.
What it costs in Cerritos
Blown in attic insulation in Cerritos typically costs $1.00 to $1.80 per square foot installed depending on depth, removal needs, and access.
How we do it
We remove and bag the old batts, air-seal all top plates and penetrations, then blow in fresh material to R-38 or higher with a settling allowance.
Blown In Fiberglass Insulation
Signs you need it
You want a fast, cost-effective attic upgrade with a material that does not settle as much as cellulose and carries strong fire-resistance credentials.
What it costs in Cerritos
Blown in fiberglass in Cerritos attics typically runs $0.90 to $1.70 per square foot installed for a standard R-38 coverage.
How we do it
We remove old material, air-seal, then blow in loose-fill fiberglass to the specified depth using baffles to protect soffit vents and a final depth check.
Loose Fill Insulation
Signs you need it
Your attic has irregular joist spacing, shallow bays, or lots of cross-bracing that make batt installation inefficient, and you need full coverage without gaps.
What it costs in Cerritos
Loose fill insulation in Cerritos attics generally falls between $0.90 and $1.80 per square foot installed, material-dependent.
How we do it
We prep the attic, air-seal, then blow the loose fill material to a consistent depth across every bay so there are no voids or compressed spots.

How long does blown in insulation last in Cerritos?
Properly installed blown in insulation lasts 30 to 50 years, though Cerritos attic heat can settle fiberglass a bit in the first year. Cellulose holds its depth better. We calculate settling allowance so you keep the target R-value. Call (833) 390-3099 for a free attic check.
Do I need to remove old attic insulation first in Cerritos?
In most 1960s through 1980s Cerritos homes, yes. Original batts are usually compressed, settled, and often contaminated by rodent activity, so blowing over them traps the problem. We remove, air-seal, and then blow fresh material.

What Cerritos Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
