Insulation Company in Tujunga, CA
Blown in insulation is the most common retrofit we install in Tujunga, and for good reason: much of the housing stock here dates to the 1920s through 1950s, when attic insulation was thin, settled, or never installed to begin with. Combine that with canyon heat that pushes attic temperatures far past what a coastal basin home sees, and the payoff for dense-packed cellulose or fiberglass is measured in immediate comfort, not abstract efficiency. Hollywood Insulation Co has served Tujunga since 2018, bringing eight manufacturer brands and three installation methods to every job. Call (866) 605-6949 for a free estimate.
Why Tujunga Homes Are Different
Tujunga sits in a sun-blasted canyon at the base of the San Gabriels, and the climate behaves nothing like the Los Angeles basin a few miles south. Summer days routinely cross into triple digits while winter nights get genuinely cold by Southern California standards, meaning a Tujunga home’s insulation has to work hard in both directions. West- and south-facing roofs on the steep canyon lots cook through the afternoon, driving attic temperatures far beyond what a shaded home in Burbank or Glendale would ever experience. That heat cycling is exactly why we regularly find blown-in insulation that has settled and compacted after years of thermal expansion and contraction.
The housing stock compounds the problem. Most of Tujunga is older single-family construction: small bungalows, ranch-style homes, and cabin-influenced builds from the 1920s through the 1950s. Many still carry original or thin attic insulation, knob-and-tube-era wiring that limits what can be buried, and vents that were never upgraded for modern airflow. Add-ons and unpermitted conversions are common here, which complicates a clean retrofit. And because much of Tujunga sits within the wildland-urban interface, insulation choices often have to balance thermal performance against ember-tolerant assembly details that coastal contractors rarely think about. This is not a market where a generic insulation approach works.
Our Main Tujunga Services
Tujunga homeowners call us most about two insulation methods: attic insulation for older homes with underperforming thermal barriers, and spray foam for canyon homes where air sealing matters as much as R-value.
Attic Insulation in Tujunga
Attic insulation in Tujunga is a different job than it is in the LA basin. The canyon’s diurnal temperature swing, with blazing afternoons and cold high-desert-adjacent nights, means the attic is the single biggest lever for comfort here. We evaluate what is already up there, determine whether it has settled or degraded, and install the right material for the home’s actual needs, whether that’s blown-in fiberglass, cellulose, or batt. Older Tujunga homes often have venting that was never upgraded, so the work frequently includes addressing airflow before adding insulation. Learn more about Attic Insulation in Tujunga.

Spray Foam Insulation in Tujunga
Spray foam insulation in Tujunga solves a specific canyon problem: air leakage. The thermal bypasses in older bungalows and ranch homes let conditioned air escape and hot canyon air pour in, and spray foam is the most complete air-sealing method we install. Closed-cell systems like Demilec add structural rigidity and moisture control, while Icynene open-cell foam provides strong R-value with a softer, more forgiving expansion profile. For homes in the wildland-urban interface, the air-sealing benefit also helps close ember-vulnerable eave and vent gaps. Read the full breakdown on Spray Foam Insulation in Tujunga.

Blown In Insulation in Tujunga
Blown in insulation in Tujunga is our most-installed attic retrofit because it works with the existing framing of older canyon homes rather than fighting it. Many of the 1920s-1950s bungalows and ranch houses in the 91042 and 91043 ZIP codes still have the original thin batt or nothing at all, and years of triple-digit attic heat have settled whatever was there into a compacted, underperforming layer. Blown-in cellulose and fiberglass reach into the irregular cavities, tight eaves, and add-on transitions that are so common in Tujunga’s older stock, creating a continuous thermal barrier without tearing out ceilings. For a deeper look at the method itself, see Blown In Insulation.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to under 6 inches, your upstairs rooms run 10 degrees hotter than downstairs in summer, or you can see bare ceiling joists from the attic access.
What it costs in Tujunga
Blown-in cellulose in Tujunga typically runs $1.20 to $2.50 per square foot installed, depending on depth, access, and whether old material must be removed first.
How we do it
We air-seal the attic floor penetrations, install baffles at the eaves to protect ventilation, then dense-pack GreenFiber cellulose to the specified R-value using a calibrated blower.
Blown In Attic Insulation
Signs you need it
Your energy bills climb every summer while the air conditioner runs constantly, or the attic feels oven-hot by mid-afternoon and radiates heat into the living space below.
What it costs in Tujunga
Blown-in attic insulation in Tujunga typically falls between $1,500 and $3,800 for a full attic on a standard canyon bungalow or ranch home, including air sealing and baffle work.
How we do it
We remove or top up the existing layer as needed, seal bypasses and penetrations, verify the venting, then blow Owens Corning fiberglass or GreenFiber cellulose to a consistent depth across the entire attic floor.
What Blown In Insulation Costs in Tujunga

How long does blown in insulation last in Tujunga’s heat?
Cellulose and fiberglass both hold up well, but Tujunga’s triple-digit attic temperatures accelerate settling. We recommend an attic inspection every 5 to 7 years. Call (866) 605-6949 to schedule a check.
Can you blow insulation over old insulation in Tujunga?
Yes, in most cases we can blow new material directly over existing insulation once we verify there is no moisture damage or knob-and-tube wiring exposed. We will assess on site and give you an honest answer.

Most attic insulation retrofits do not require a building permit in Los Angeles, but if your Tujunga home has unpermitted add-ons or you are doing spray foam in a conditioned attic, the rules can differ. We can tell you exactly what applies to your house after one look.
Yes, and this is a common condition in 1920s-1950s Tujunga bungalows. Insulation cannot be blown directly over live knob-and-tube wiring, so we evaluate the attic and work with you on the right sequence before any material goes in. Call (866) 605-6949 to have us take a look.

What Tujunga 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."
— Miguel Garcia
