Insulation Company in Cerritos, CA
Blown in insulation is the workhorse upgrade for Cerritos homes built in the 1960s and 70s, because original R-11 attic batting has lost most of its effectiveness after five decades of Los Angeles Basin heat. We install loose fill cellulose and fiberglass from GreenFiber, CertainTeed, and Johns Manville, plus foam and batt systems where they fit better. If your attic runs hot enough to make the upstairs feel like a different climate zone, or your summer AC bill keeps climbing, call (866) 605-6949 and we’ll take a look.
Why Cerritos Homes Are Different
Cerritos was built out as a master-planned suburb in the 1960s and 70s, which means most of the housing stock is wood-frame stucco tract homes on low-pitch roofs. Those homes went up with R-7 wall insulation and R-11 attic batts, and a lot of that material is now compressed, dusty, or simply missing in spots. The original radiant-barrier staples you see in some Cerritos attics were a nice idea in 1972, but they were never a substitute for proper R-value.
The climate here does something specific to attics. Cerritos gets mild coastal influence, but summers are long and dry with intense afternoon sun. Attic temperatures routinely spike past 140°F, which cooks insulation and makes the duct runs above the ceiling work against your air conditioner. What we find in Cerritos attics more than almost anywhere else in the LA Basin is unsealed, sagging ductwork that has gone through decades of heat cycling. So a blown in insulation job in Cerritos is rarely just about adding R-value. It’s about sealing the thermal envelope and getting those ducts back to doing their job before we bury them in new material.
Homeowners here are often second or third owners entering a serious remodel wave. They bought a well-kept 1970s home, then discovered the attic was never upgraded. That’s the exact situation where a dedicated insulation specialist with multiple installation methods makes the difference.
Our Main Cerritos Services
Cerritos homeowners call us most often about two things: attic insulation that has finally hit the end of its useful life, and spray foam jobs where air sealing is the real goal. Here’s what each one involves in this city.
Attic Insulation in Cerritos
Most Cerritos attics from the 1970s still have the original fiberglass batts, and they’re doing almost nothing now. We remove the old material, air-seal the top plates and penetrations, then install new insulation matched to the home’s actual needs. The low-pitch roofs common in Cerritos make access tight, so we work carefully around trusses and ductwork rather than just blowing material in and hoping. Read more about our Attic Insulation in Cerritos service.
Spray Foam Insulation in Cerritos
Cerritos attics that spike past 140°F in summer are prime candidates for spray foam, because foam does something batts and blown-in material can’t: it air-seals while it insulates. We install both open-cell and closed-cell systems from Icynene and Demilec, and in these mid-century tract homes the air-sealing effect is often worth more than the R-value by itself. See the full breakdown on our Spray Foam Insulation in Cerritos page.

Blown In Insulation in Cerritos
Blown in insulation is the most common fix we install in Cerritos because it works so well in low-pitch attics where the original R-11 batts have failed. These 1970s tract homes have attics that spike past 140°F in summer, and the original fiberglass has compressed to maybe R-5 or worse. Blowing in fresh cellulose or fiberglass gets you back to R-38 or R-44, cuts the heat load on your AC, and does it without tearing out ceilings. It’s also the most cost-effective way to top off an attic that already has some insulation, which is exactly the situation in most Cerritos homes. Learn more about our Blown In Insulation approach.
Cellulose Insulation
Signs you need it
Your attic insulation is dusty, settled flat between the joists, or measures under R-19 when you check it with a ruler.
What it costs in Cerritos
Blown-in cellulose in Cerritos typically runs $1.50 to $2.80 per square foot installed, depending on depth and whether the old material needs removal first.
How we do it
We air-seal the attic floor, then blow in GreenFiber recycled cellulose to the target depth using two-person teams that walk the hose and keep coverage even.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run 8 to 10 degrees warmer than downstairs in summer, and your attic feels like a furnace when you open the hatch.
What it costs in Cerritos
Expect $1,200 to $2,800 for a complete blown-in attic job in a typical Cerritos tract home, including removal of old R-11 batting and air sealing.
How we do it
We remove the failed batts, seal every top plate and wire penetration with foam, then blow in fresh insulation to R-38 or higher across the entire attic floor.
Blown In Cellulose Insulation
Signs you need it
You want the recycled-content option that performs better than fiberglass in extreme attic heat and resists air movement through the material itself.
What it costs in Cerritos
Blown-in cellulose in Cerritos costs $1.50 to $2.80 per square foot installed, which lands most 1,200 to 1,800 square foot attics between $1,800 and $4,000 all in.
How we do it
We run the cellulose through a high-output blowing machine, and the material’s natural density lets it fill around ducts, wires, and trusses without leaving gaps.
Blown In Fiberglass Insulation
Signs you need it
You prefer the lighter-weight option, or you’re topping off an existing attic where fiberglass is already in place and you want to keep materials consistent.
What it costs in Cerritos
Blown-in fiberglass runs $1.00 to $2.10 per square foot in Cerritos, making it the lower-cost option when you need to add depth quickly.
How we do it
We blow in Johns Manville or CertainTeed loose-fill fiberglass to the required depth, checking coverage with depth markers as we go across the attic.
Loose Fill Insulation
Signs you need it
You have an attic with uneven joist spacing, lots of cross-bracing, or tight corners where batts were never cut to fit properly.
What it costs in Cerritos
Loose fill in Cerritos costs $1.00 to $2.80 per square foot installed, depending on whether you choose fiberglass or cellulose and how deep you need it.
How we do it
We blow the material into every cavity and corner, skipping the gaps and compression that happen when batts get stuffed into irregular spaces.
What Blown In Insulation Costs in Cerritos
| Item | Typical range in Cerritos |
|---|---|
| Blown-in fiberglass (attic) | $1.00 – $2.10 per sq ft installed |

How long does blown in insulation last in a Cerritos attic?
Cellulose and fiberglass loose fill both last 20 to 30 years in a Cerritos attic if the roof stays dry and the material stays at depth. The bigger issue here is the original 1970s batting failing after 50 years, not the new material wearing out. Call (866) 605-6949 if you want us to check what’s actually up there now.
Can you do blown in insulation without removing the old stuff?
You can blow new material over old batts if the existing insulation is dry, uncompressed, and free of rodent damage. In Cerritos tract homes from the 1960s and 70s we usually recommend removal first, because the original material is often broken down and hiding air leaks. Call (866) 605-6949 for a straight answer on your attic.
Brands We Service in Cerritos

That means no two-week waits on the common materials. See the full lineup on our brands page.

If you’re in a planned development with strict rules, we’ll provide a scope-of-work letter you can submit. The approval process is usually quick since insulation is considered maintenance, not modification.

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."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
