Insulation Company in Cerritos, CA
Blown in insulation is the retrofit workhorse for Cerritos, and that’s what most homeowners here call us about first. The city’s housing stock dates overwhelmingly to the 1960s through 1980s, which means original attics were built to R-11 or R-19 standards that made sense when energy was cheap and air conditioning was optional. It isn’t optional anymore. We install blown in fiberglass and cellulose across 90703, and most jobs come down to one thing: getting loose fill insulation up into a low-pitch attic and dense-packing walls that were never insulated in the first place.

Why Cerritos Homes Are Different
Cerritos is a master-planned, fully built-out city. Nearly every residential structure went up between the 1960s and the 1980s buildout, so we don’t see new construction here. We see tract houses with original foil-backed batts stapled under low, uniform rooflines, and townhomes on the planned street grid with uninsulated exterior walls. The homes near Cerritos Park East are a good example: the original 1970s foil-faced batts under those low-pitch roofs are often compressed, torn, or pulled apart by decades of HVAC and duct work. That foil backing loses its reflective value once it’s covered in dust, and the batt itself loses R-value when it’s compressed. Afternoon sun on west-facing roofs can push attic temperatures well past 140°F even in October, and that heat radiates down into living spaces all evening.
The climate here is inland-adjacent LA Basin: long, hot, dry summers and mild winters. That flips the insulation equation compared to colder climates. Attic heat load drives comfort and energy bills, not cold outdoor air. Reflective strategies on south- and west-facing roof decks matter more than chasing a higher attic R-value alone. We account for that when we recommend materials, because adding R-38 fiberglass over a dirty, torn foil batt without addressing the radiant heat problem is money spent on the wrong priority.
Our Main Cerritos Services
Two services account for most of the calls we get from Cerritos homeowners: attic insulation retrofits and spray foam air sealing. Here’s what each one involves in this city.
Attic Insulation in Cerritos
Most Cerritos attics have the original R-11 or foil-backed batts, and after 40 to 60 years of heat cycling, dust, and duct work, they’re underperforming. We remove or top-dress the old material depending on condition, air seal the ceiling plane where we can, and blow in fresh fiberglass or cellulose to bring the attic up to current code levels for this climate zone. The low, uniform rooflines the city’s design standards enforce make access predictable, but they also mean shallow attics where careful venting and baffle work matter. Attic Insulation in Cerritos has the full breakdown on materials and pricing.
Spray Foam Insulation in Cerritos
Spray foam earns its keep in Cerritos when the job calls for air sealing, not just insulation. Open-cell foam works well in attics where the roofline needs to breathe, while closed-cell foam makes sense on rim joists, crawl spaces, and any area where moisture or structural rigidity is a concern. In an older tract home with duct runs through a hot attic, foam can cut the heat gain at the source in a way blown in fiberglass alone can’t. Spray Foam Insulation in Cerritos covers the differences between open-cell and closed-cell in more detail.

Blown In Insulation in Cerritos
Blown in insulation is the right retrofit for most Cerritos homes because it solves two problems at once. First, it brings under-insulated attics up to current standards without tearing out ceilings. Second, it can be dense-packed into the uninsulated exterior walls found across 1960s and 1970s tract housing in this city, which no batt installation can do without opening drywall. With long summers and attic temperatures routinely exceeding 140°F, getting loose fill up to R-38 or R-44 in the attic is usually the single highest-impact energy upgrade available. We install both fiberglass and cellulose through our Blown In Insulation service, and the right choice depends on your attic’s condition, access, and existing material.
Cellulose Insulation
Signs you need it
Your attic has old, settling insulation, gaps around light fixtures, or you can see the tops of ceiling joists through the existing material.
What it costs in Cerritos
Cellulose insulation in a Cerritos attic typically runs $1.20 to $2.10 per square foot installed, depending on depth and whether we’re topping off or starting fresh.
How we do it
We dense-pack or loose-fill recycled paper cellulose with a blowing machine, building to the target R-value at a consistent depth across the attic floor, including around framing and duct work.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms are 8 to 12 degrees warmer than the rest of the house in summer, or your AC runs all afternoon and the house still won’t hold temperature.
What it costs in Cerritos
Blown in attic insulation in Cerritos generally costs $1,800 to $4,200 for a typical single-family home, with final numbers tied to square footage and the R-value you’re targeting.
How we do it
We prep the attic by air sealing penetrations where the old insulation allows, install baffles at the eaves to preserve ventilation, then blow fiberglass or cellulose to the agreed depth.
Blown In Fiberglass Insulation
Signs you need it
Your current attic insulation is compressed, stained, or blown thin in spots, and you want a clean, non-settling material with predictable R-value performance.
What it costs in Cerritos
Blown in fiberglass in a Cerritos home ranges from $1.10 to $2.00 per square foot installed, with R-38 to R-44 as the common depth for this climate.
How we do it
We blow loose fiberglass with a calibrated machine, checking bag count against square footage to confirm the installed R-value rather than eyeballing depth alone.
What Blown In Insulation Costs in Cerritos
| Item | Typical range in Cerritos |
|---|---|
| Cellulose insulation (per sq ft) | $1.20 – $2.10 |
| Blown in attic insulation (full house) | $1,800 – $4,200 |
| Blown in fiberglass (per sq ft) | $1.10 – $2.00 |
Is blown in insulation worth it in Cerritos?
Yes. Original R-11 attics lose heat through the ceiling all summer, and upgrading to R-38 or R-44 typically pays back in lower AC bills within a few years. Cerritos heat makes attic insulation the highest-ROI energy project. Call (866) 393-6041 for a free estimate on your specific attic.
Can you dense-pack walls in a 1970s Cerritos tract home?
Yes, and we do it regularly. Dense-packing cellulose into uninsulated exterior walls is the least invasive way to insulate them, requiring only small drill holes that are patched after. Call (866) 393-6041 to find out if your walls qualify.
Brands We Service in Cerritos
We work across eight manufacturer lines, so the material recommendation comes from your home’s needs rather than what we happen to stock. In Cerritos we commonly install Owens Corning and Johns Manville fiberglass, GreenFiber cellulose for dense-pack and attic work, and Demilec spray foam systems when air sealing is the priority. Parts and materials are staged locally, and most retrofit jobs can be scheduled within a few days. See our brands for the full list.
