Insulation Company in Hollywood, CA
Blown in insulation solves a problem Hollywood homeowners know all too well: rooms that never hold temperature because the walls and attic cavities were never properly filled. Most of Hollywood’s housing stock dates to the 1920s and 1930s, when insulation was an afterthought or skipped entirely, and the result is homes that bake in summer, leak cooled air, and let street noise pour through exterior walls. Aliso Viejo Insulation Co has served Hollywood since 2014, installing blown in insulation, attic insulation, and spray foam with the material depth to match the right product to each home’s construction.

Why Hollywood Homes Are Different
Hollywood’s thermal and acoustic problems come from a rare combination of building age, density, and geography. The flats are packed with 1920s-era Spanish Colonial and Craftsman bungalows and courtyard apartments, many of which have never had insulation added. Walk through a courtyard building off Hollywood Blvd and you’ll find shared party walls with nothing but lath and plaster between units, which means a conversation next door sounds like it’s in your living room. Then the hills change everything. Hillside homes in the Hollywood Hills face steeper solar exposure, different wind patterns, and, in many cases, fire-zone requirements that affect which insulation materials are appropriate.
The climate does something specific here too. Hollywood’s Mediterranean weather means cooling loads dominate the equation. A house in Hollywood spends far more energy fighting heat than cold, which is why attic heat control and radiant barriers often matter more than deep cold-weather R-value. The basin’s heat-island effect, amplified by asphalt and dense development along Sunset and Santa Monica Blvd, keeps night-time temperatures elevated long after sundown. And then there’s the noise: street traffic on Franklin Ave, aircraft approaching Burbank, nightlife spilling out of clubs along the Boulevard. For many Hollywood homeowners, sound isolation is the feature that finally convinces them to insulate.
Our Main Hollywood Services
Blown in insulation is the primary service Hollywood homeowners request, but two related specialties cover most of the remaining calls. Here’s what each involves in Hollywood’s specific housing conditions.
Attic Insulation in Hollywood
Attics in Hollywood bungalows and Spanish Colonial homes are usually accessible but under-insulated, often with a thin layer of old fiberglass that settled decades ago. That’s a real problem when summer sun beats on tile and composition roofs, turning the attic into an oven that radiates heat into living spaces below. We assess existing attic insulation, check ventilation, and add insulation to bring the thermal boundary up to what Hollywood’s cooling-dominated climate actually needs. See the full breakdown on our Attic Insulation in Hollywood page.
Spray Foam Insulation in Hollywood
Spray foam has a specific role in Hollywood’s construction mix. For hillside homes with irregular framing, cathedral ceilings, or hard-to-reach rim joists, spray foam creates an air seal that batts simply cannot match. It’s also strong in courtyard apartments where party walls offer limited cavity depth and the goal is both thermal performance and sound attenuation. Homeowners who want open-cell versus closed-cell chemistry matched to their specific wall assembly and budget will find the full details on our Spray Foam Insulation in Hollywood page.

Blown In Insulation in Hollywood
Blown in insulation is the most common retrofit choice in Hollywood because the housing stock here was rarely built with insulation. A 1920s bungalow in the flats often has empty wall cavities and a thin layer of dust where the attic insulation should be. Blown in cellulose or fiberglass fills those cavities without tearing open walls, making it the fastest, least invasive path to real comfort in Hollywood’s older homes. Our team installs Blown In Insulation with methods matched to each home’s framing style, using materials from manufacturers like GreenFiber and Owens Corning. Here are the specific sub-jobs we handle most often in Hollywood.
Cellulose Insulation
Signs you need it
Rooms on the top floor feel hot within an hour of the morning sun hitting the roof, and interior walls facing the street let traffic rumble through all day.
What it costs in Hollywood
Cellulose insulation in Hollywood typically runs $1.10 to $1.50 per square foot installed, depending on depth and whether the job targets an attic or wall cavities.
How we do it
We drill access points at the top and bottom of wall cavities, blow the cellulose to a dense, consistent fill, then patch and clean up so the walls look untouched.
Blown In Attic Insulation
Signs you need it
The upstairs is 10 to 15 degrees hotter than the rest of the house by mid-afternoon, or your attic has less than six inches of existing insulation.
What it costs in Hollywood
Blown in attic insulation in Hollywood generally falls between $1,800 and $3,200 for a full attic in a 1,200-1,800 square foot bungalow, depending on depth and material.
How we do it
We air-seal bypasses around plumbing vents and wiring penetrations first, then blow insulation to the target depth and fluff it out to an even, consistent layer.
Loose Fill Insulation
Signs you need it
Rooms feel drafty in winter even with the windows closed, and attic insulation is thin, patchy, or has settled below the floor joists.
What it costs in Hollywood
Loose fill insulation projects in Hollywood average $1,500 to $2,800 depending on square footage, access, and whether we remove old insulation first.
How we do it
We remove or level existing insulation where needed, then blow the loose fill fiberglass or cellulose to the specified depth and verify coverage with a depth gauge.
What Blown In Insulation Costs in Hollywood
| Item | Typical range in Hollywood |
|---|---|
| Cellulose insulation per sq ft installed | $1.10 – $1.50 |
| Blown in attic insulation, full attic | $1,800 – $3,200 |
| Loose fill insulation, typical project | $1,500 – $2,800 |
The biggest cost variables in Hollywood are access, existing insulation removal, and whether the job includes air sealing. A hillside home with steep roof access or a packed attic full of old boxes and wiring will always cost more than an open, clean attic in a bungalow. We quote fixed prices before work starts so you know exactly what the job costs, with no per-hour surprises.
How long does blown in insulation take in Hollywood?
A typical attic takes four to six hours, and wall cavity work in courtyard apartments usually runs one full day. Call (877) 352-4780 to get a time estimate for your specific Hollywood home.
Can blown in insulation help with street noise in Hollywood?
Yes, dense-packed cellulose measurably reduces sound transmission through walls and ceilings, which matters a lot on busy streets like Hollywood Blvd and Sunset. The acoustic improvement is noticeable within a day of installation.

We handle both.

— Marcy Anderson"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Sanjay Patel"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
