Insulation Company in Los Angeles, CA
Blown in insulation solves a very specific Los Angeles problem: attics that turn into convection ovens by noon and radiate that heat straight down into living space for the next eight hours. East Los Angeles Insulation Co has served Los Angeles since 2018, and most of the homes we work on are 1900s to 1950s wood-frame bungalows and stucco duplexes with minimal settled attic insulation and attics that hit 130°F plus in summer. The fix is usually loose fill blown dense and even across the attic floor, sealing the thermal boundary between that superheated attic and the rooms below. Call (866) 566-0304 for a free estimate, and we’ll tell you exactly what’s up there now and what it would take to fix it.
Why Los Angeles Homes Are Different
Los Angeles is a cooling-dominated market, which flips the usual insulation conversation on its head. Nobody here is worried about pipes freezing; they’re worried about the second floor of a Koreatown fourplex hitting 88°F at midnight because the attic spent all afternoon baking in direct sun. The unshaded, low-pitch or flat roofs common across South LA and East Hollywood make it worse: there’s often barely any attic cavity to begin with, and what little insulation exists has usually settled to R-19 or less after decades of service.
The housing stock itself presents challenges most national insulation guidance never addresses. Those 1920s Spanish stucco bungalows in the 90006 and 90007 ZIP codes were built long before anyone thought about thermal performance, with unsealed wall cavities, original knob-and-tube-era penetrations around windows and doors, and attic access that is often a single small scuttle hole in a hallway closet. Getting loose fill or batts into spaces like that takes a crew who has done it before and knows how to work fast in a 130°F attic without damaging original lath and plaster. Duct losses in hot attics are a huge part of the picture too: sealed, insulated attics mean the cool air your AC worked to produce actually reaches the rooms instead of warming up six degrees on the way through the attic chase.
Our Main Los Angeles Services
Los Angeles homeowners call us most often about two things: getting their attic insulation back up to where it should be, and sealing problem areas with spray foam where traditional insulation cannot reach. Both are covered in depth on their own pages, but here’s the short version.
Attic Insulation in Los Angeles
Attic work in Los Angeles is rarely a simple “add more” job. In older South LA and Koreatown homes, we typically find settled fiberglass, gaps around recessed lights and chimney chases, and bathroom vents that dump into the attic instead of outside. The work includes air sealing those bypasses, checking the existing depth, and bringing the attic up to a proper R-value for our climate. This is exactly the kind of diagnostic-first job that separates a dedicated insulation contractor from a generalist. See the full breakdown at Attic Insulation in Los Angeles.
Spray Foam Insulation in Los Angeles
Spray foam is the right tool for Los Angeles flat roofs, kneewalls, rim joists, and any cavity where air movement is the real problem. In 1920s stucco duplexes and mid-century fourplexes, air infiltration through unsealed exterior wall penetrations often matters more than the R-value of what is stuffed in the cavity. Closed cell foam seals and insulates in one pass, which is why we run Icynene and Demilec for this work. Full product and application details live at Spray Foam Insulation in Los Angeles.
Blown In Insulation in Los Angeles
Blown in insulation is our most requested service in Los Angeles because it is the fastest, most cost-effective way to fix an under-insulated attic in a 1900s to 1950s home. In neighborhoods like Koreatown, South LA, and East Hollywood, we routinely find attics with R-11 or less of settled fiberglass: nowhere near enough to stop a 90°F plus afternoon from turning the rooms below into an oven by 4 p.m. Blown in loose fill, installed dense and even across the attic floor, restores that thermal boundary quickly and corrects the uneven coverage that batts rarely achieve in tight, low-slope attics.

Cellulose Insulation
Signs you need it
Your attic insulation has settled to the top of the joists or below, and upstairs rooms run five to ten degrees hotter than the rest of the house on sunny days.
What it costs in Los Angeles
Blown-in cellulose in Los Angeles typically runs $1.20 to $2.10 per square foot of attic area, depending on depth and access.
How we do it
We air-seal the attic floor penetrations first, then blow cellulose to the target depth using a two-person hose-and-machine setup, one tech in the attic and one feeding the hopper below.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel hot by mid-afternoon, your AC runs for hours without cycling off, and the existing attic insulation is thin, patchy, or compressed in places.
What it costs in Los Angeles
Blown-in attic insulation in Los Angeles typically costs $0.90 to $2.10 per square foot, with most 1,200-square-foot attic floors landing between $1,100 and $2,500.
How we do it
We map the attic, seal bypasses around lights, wires, and top plates, then blow to an even depth across the entire attic floor in one continuous pass.
Blown In Cellulose Insulation
Signs you need it
Your attic has old, settling insulation with visible gaps and bare spots, and you want a denser, recycled-content material with better air-blocking performance than fuzzy fiberglass.
What it costs in Los Angeles
Blown-in cellulose in Los Angeles typically runs $1.20 to $2.10 per square foot installed, including removal of lightly settled existing material if needed.
How we do it
We prep the attic floor, run the hose through the scuttle or kneewall access, and blow cellulose to code-plus depth, checking density as we go rather than guessing by eye.
Blown In Fiberglass Insulation
Signs you need it
You need an economical, fast-install attic insulation that will not absorb moisture and works well in the tight, low-clearance attics common on South LA and Koreatown bungalows.
What it costs in Los Angeles
Blown-in fiberglass in Los Angeles typically runs $0.90 to $1.60 per square foot, making it the most budget-friendly option for a full attic re-insulation.
How we do it
We seal the attic floor penetrations, then blow loose fiberglass to the specified depth using a calibrated machine so the R-value is consistent wall to wall.
Loose Fill Insulation
Signs you need it
You have an irregular attic floor with lots of framing, cross-bracing, or low spots where batts cannot sit flush, leaving gaps that leak conditioned air.
What it costs in Los Angeles
Loose fill insulation in Los Angeles typically runs $0.90 to $2.10 per square foot, depending on whether we use fiberglass or cellulose and how deep you want to go.
How we do it
We blow loose material across the entire attic floor, working it into corners and around obstructions so coverage is continuous and the specified depth is met everywhere.
What Blown In Insulation Costs in Los Angeles

| Blown-in attic insulation (full attic floor) | $0.90 to $2.10 per sq ft |
| Blown-in cellulose | $1.20 to $2.10 per sq ft |

Does blown in insulation help with summer cooling bills in Los Angeles?
Yes. Most Los Angeles heat gain enters through the attic ceiling, so restoring a proper loose fill layer keeps upstairs rooms measurably cooler and shortens AC runtime, which shows up directly on summer electric bills.
How long does blown in insulation take in a Los Angeles attic?
Most single-family attics in Los Angeles take one crew about half a day from setup to cleanup. Tight scuttle access or a full air-seal pass can push it to a full day. Call (866) 566-0304 for a time estimate on your specific attic.
Brands We Service in Los Angeles
We stock Icynene and Demilec spray foam rigs for Los Angeles jobs, carry Owens Corning batts for cavity work, and keep GreenFiber loose fill on the truck for blown-in cellulose callouts across the city. Most products are on hand locally, which means we are not waiting on a distributor when your attic is already hot. See the full lineup at our brands.

What pushes price up in Los Angeles is access: flat roofs and small scuttle holes mean our techs are working in 130°F attics with limited mobility, and that takes longer and costs more per square foot. You get an upfront, line-item price before we start, and that number does not change unless we find something structural neither of us could see from below.

What Los Angeles Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
- Diego Castillo"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."
- Gilbert Herrera"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."
