Insulation Company in North Hollywood, CA
Blown in insulation in North Hollywood is the workhorse retrofit for the San Fernando Valley’s older housing stock, where summer attic temperatures can climb 40 to 50 degrees above the outdoor air. We specialize in loose-fill cellulose and fiberglass, dense-packed into walls and attics of 1920s bungalows and mid-century tract homes that were built long before insulation was standard practice. If your North Hollywood home has uneven temperatures between rooms or an attic that turns into an oven by noon, call us at (855) 362-0195 for a free estimate.
Why North Hollywood Homes Are Different
North Hollywood sits deep in the San Fernando Valley, where July and August routinely bring 95 to 105 degree days. Attics here absorb that heat all afternoon and hold it well past sunset. Much of the housing stock dates from the 1920s through the 1950s, with bungalows and cottage courts near the NoHo Arts District that were framed before air conditioning existed and before Title 24 energy codes told builders to insulate anything. The result is a lot of homes with bare attic floors or a thin layer of paper-faced batts that have collapsed under decades of heat. Knob-and-tube wiring is common in these older properties, which means insulation work has to be done carefully and often starts with air-sealing and electrical assessment rather than simply blowing in material. Toward the 91605 and 91606 ZIP codes, mid-century tract homes from the 1960s and 1970s are only marginally better insulated, and apartment buildings there face the same attic heat gain problem on a larger scale. The classic North Hollywood job is a 1940s bungalow with a low-pitch roof, a shallow broiling attic, and no insulation at all.
Our Main North Hollywood Services
Most North Hollywood homeowners reach out to us about two things: attics that need to be brought up to modern R-values, and spray foam for hard-to-reach or moisture-prone spaces. Here’s what each involves in this part of the Valley.
Attic Insulation in North Hollywood
Attic work in North Hollywood often starts with removing whatever little insulation exists, air-sealing the floor penetrations, and then building up to R-38 or R-49 depending on the home’s age and roof design. Older bungalows near the Arts District frequently have shallow attics where access is tight and venting is inadequate, so the job involves more than just blowing in material. We address the whole thermal boundary, including radiant barrier where the sun exposure justifies it. For the full breakdown of attic services specific to this area, see Attic Insulation in North Hollywood.
Spray Foam Insulation in North Hollywood
Spray foam makes sense in North Hollywood when there’s an unvented attic, a bonus room over a garage, or a crawlspace that pulls in hot Valley air. We offer both open-cell and closed-cell formulations through Icynene and Demilec, matched to the moisture and structural needs of each space. Closed-cell also adds shear strength to older framing, which matters on some of the 1920s bungalows that have settled over the decades. Read more at Spray Foam Insulation in North Hollywood.

Blown In Insulation in North Hollywood
Blown in insulation is the fastest way to bring a North Hollywood attic or wall cavity from zero to a proper R-value without tearing the house apart. Most of the homes we work on in the 91611 and 91612 ZIP codes were built with empty wall cavities and bare attic floors, so dense-packed cellulose or loose-fill fiberglass makes an immediate difference in both summer heat gain and winter heat loss. This is where Blown In Insulation as a method really earns its keep: it fills irregular cavities in older framing, settles around obstacles like knob-and-tube wiring when properly installed, and costs substantially less than spray foam per square foot.
Cellulose Insulation
Signs you need it
Your home was built before 1980, the attic floor is bare or has batts that look flattened and gray, and upstairs rooms run 10 to 15 degrees hotter than the rest of the house in summer.
What it costs in North Hollywood
Blown-in cellulose for an average North Hollywood attic typically runs $1.10 to $2.80 per square foot installed, so a 1,200-square-foot attic usually lands between $1,320 and $3,360.
How we do it
We air-seal the attic floor penetrations first, then dense-pack or loose-fill GreenFiber cellulose to the R-value target using a calibrated blowing machine, with depth markers set so you can see the final depth yourself.
Blown In Attic Insulation
Signs you need it
Your air conditioner runs almost constantly from June through September, ceiling surfaces feel warm to the touch in the late afternoon, and you can feel heat radiating downward after sunset.
What it costs in North Hollywood
Attic-only blown-in projects in North Hollywood generally fall between $900 and $2,400 depending on square footage and current insulation depth, putting most homes in the $1,400 to $2,100 range.
How we do it
We remove or top up existing material as needed, install or repair vent baffles at the eaves, air-seal top plates and penetrations, then blow insulation to a uniform depth that meets code minimums for climate zone 3B.
Blown In Cellulose Insulation
Signs you need it
You want a recycled-content material, you have irregular joist spacing or odd cavities in an older North Hollywood home, or you want better resistance to air movement than fiberglass can offer.
What it costs in North Hollywood
Dense-packed wall cellulose in North Hollywood runs $2.00 to $4.20 per square foot of wall area, including drilling, filling, and patching access holes.
How we do it
We drill small access holes from the exterior or interior, dense-pack GreenFiber cellulose under pressure until the cavity reaches the target density, then patch and texture the openings to match the surrounding surface.
Blown In Fiberglass Insulation
Signs you need it
You have an open attic with standard framing, you want a faster and often less expensive loose-fill option, and your current fiberglass batts are thin, torn, or discolored from years of Valley heat.
What it costs in North Hollywood
Loose-fill fiberglass attic insulation in North Hollywood runs $1.80 to $2.60 per square foot installed, with most 1,000 to 1,500-square-foot attics finishing between $1,800 and $3,900.
How we do it
We blow Owens Corning or Johns Manville loose-fill fiberglass to the specified depth, using a machine calibrated for the material’s settling rate so the final R-value matches the depth chart, not the freshly blown height.
What Blown In Insulation Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Attic blown-in insulation (1,000 – 1,500 sq ft) | $1,400 – $3,900 |
| Wall cavity dense-pack (per sq ft of wall) | $2.00 – $4.20 |
| Attic air-sealing and prep (typical single-story home) | $400 – $900 |
How long does blown in insulation take in North Hollywood?
Most attic jobs are finished in one day. Wall cavity drilling adds time, especially on stucco exteriors common in North Hollywood, so plan for a second morning if we’re dense-packing multiple rooms.
Is blown in insulation enough for North Hollywood summers?
Yes, when the attic is air-sealed first and the material is blown to R-38 or higher. The heat gain problem here is real, but a properly sealed and insulated attic reduces it before your AC has to fight it.

What North Hollywood 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."
— Emily Gallagher"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Luis Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
