Insulation Company in North Hollywood, CA
Blown in insulation solves the single biggest comfort problem in North Hollywood: attic heat gain that turns bungalows and small apartment buildings into ovens by mid-afternoon. Most homes here were built between the 1920s and 1950s, when insulation was an afterthought, and the San Fernando Valley summers now push well past 100°F. We retrofit those shallow, under-insulated attic cavities with blown-in fiberglass and cellulose, dropping attic temperatures and taking real load off the air conditioner. Call (866) 393-6041 for a free estimate.
Why North Hollywood Homes Are Different
North Hollywood sits in a hot-summer pocket of the East San Fernando Valley, where the housing stock was built for a milder climate than the one it actually gets. The 91601 and 91602 blocks are dense with 1920s to 1950s California bungalows and small stucco single-family homes, plus a thick band of mid-century and later low-rise apartment buildings. Most of these structures have shallow attics with little more than a thin, settled layer of old fiberglass or nothing at all. The result is predictable: attic temperatures climb to 140°F and higher in July and August, and that heat radiates down through the ceiling for hours after sundown.
What makes North Hollywood different from coastal Los Angeles is that the retrofit math flips. In the Valley, attic insulation and radiant-barrier work deliver far more comfort per dollar than wall insulation, because the dominant load is solar heat gain through the roof. Mild winters mean heating is secondary. For older NoHo homes with knob-and-tube-era construction details, blown-in insulation is often the only practical retrofit, since it fills irregular cavities without tearing open walls or ceilings. We have served North Hollywood since 2014, and these attic conditions are consistent across the ZIP codes we cover: 91611, 91612, 91615, and 91616.
Our Main North Hollywood Services
North Hollywood homeowners call us most about two things: getting their attics insulated before summer and sealing leaky building envelopes with spray foam. Each service has its own dedicated North Hollywood page.
Attic Insulation in North Hollywood
In the bungalow blocks of 91601 and 91602, we commonly find original attic spaces with a thin layer of settled fiberglass or none at all, and shallow roof cavities that make blown-in and batt retrofits the go-to fix before summer heat peaks. The job usually means air sealing the attic floor first, then installing insulation to the R-value that makes sense for a Valley summer. Read the full breakdown on our Attic Insulation in North Hollywood page.
Spray Foam Insulation in North Hollywood
Older NoHo homes leak air through rim joists, wall plates, and attic hatches, and spray foam is the only product that seals and insulates in one step. For small apartment buildings and converted garages, closed-cell foam from Demilec adds structural strength while it air seals, which matters in a housing stock this old. The details, including vapor control and R-value choices, are on the Spray Foam Insulation in North Hollywood page.

Blown In Insulation in North Hollywood
Blown in insulation is the workhorse retrofit for North Hollywood’s aging housing stock. In the bungalow blocks of 91601 and 91602, we routinely open attic hatches to find little more than a dusting of degraded fiberglass, and shallow roof cavities that make blown-in cellulose or fiberglass the fastest, least invasive way to bring a home up to modern performance. The payoff is immediate in a Valley summer: a properly insulated attic can hold indoor temperatures 10 to 15 degrees steadier, and your AC stops running nonstop from 2 p.m. to 8 p.m. Our Blown In Insulation work covers cellulose, fiberglass, and loose fill, all installed by the same crew that handles our attic and spray foam jobs.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the joists, or you can see bare drywall between the framing members.
What it costs in North Hollywood
Blown-in cellulose in North Hollywood typically falls between $1.10 and $1.95 per square foot installed, depending on depth and access.
How we do it
We air seal the attic floor penetrations, then blow GreenFiber cellulose to the target R-value with a two-person hose crew.
Loose Fill Insulation
Signs you need it
Your home has shallow, irregular attic cavities, vermiculite, or old batts that no longer fill the joist bays.
What it costs in North Hollywood
Loose fill insulation in North Hollywood runs from $1.00 to $2.10 per square foot installed.
How we do it
We remove or cap any compromised material, prep the attic, and blow loose fill to an even, consistent depth across the entire floor.
What Blown In Insulation Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Blown-in fiberglass insulation | $1.00 – $2.10 per sq ft installed |
| Blown-in cellulose insulation | $1.10 – $1.95 per sq ft installed |
| Loose fill insulation | $1.00 – $2.10 per sq ft installed |
Does blown-in insulation really help in North Hollywood summers?
Yes. Blown-in insulation slows the radiant heat that builds in a Valley attic from pushing down through your ceilings, which is the dominant cooling load in North Hollywood. Homes here see the biggest comfort shift from attic work, not wall work.
Can you blow insulation into an older NoHo attic without removing the old stuff?
In most cases, yes, as long as the existing material is dry and free of vermiculite or rodent damage. We inspect first, then blow fresh insulation over the old layer to reach the target R-value. Call (866) 393-6041 for an inspection.

We install blown-in fiberglass and cellulose from Owens Corning, Johns Manville, and GreenFiber, plus spray foam from Demilec. Parts and material are stocked locally for North Hollywood jobs, which means most retrofits are scheduled within a week. See the full list on our brands page.
