Insulation Company in Hollywood, CA
Blown in insulation solves a problem Hollywood homeowners know well: rooms that bake in the afternoon sun while the AC never stops running. Fountain Valley Insulation specializes in blown-in work for the pre-war bungalows, Spanish Colonial duplexes, and 1960s stucco apartments that dominate the 90028 ZIP code. Most of these buildings were constructed before insulation was standard practice, and many still have nothing but empty wall cavities and bare attic floors. We match the material to your Hollywood home, not the other way around. Call (833) 390-3099 for a free estimate.
Why Hollywood Homes Are Different
Hollywood’s housing stock runs heavily toward 1920s-1940s Spanish Colonial and Craftsman bungalows, duplexes, and courtyard apartments framed with wood lath and plaster. These structures predate modern insulation entirely. Many still have balloon-frame wall cavities that run open from foundation to attic, and original asphalt-tar flat roofs with no thermal barrier at all. When we open a wall in an older Hollywood apartment building, it’s common to find the cavities packed with nothing but 1920s newspaper and plaster debris from some long-ago remodel. That’s not insulation; it’s just what was left behind.
The climate makes matters worse. Hollywood’s hot, dry, sun-baked summers drive cooling loads far more than heating. Intense afternoon sun on unshaded stucco and flat roofs pushes attic and roof-deck temperatures well past comfortable, and top-floor units in courtyard buildings become unbearable every August. Occasional winter rains and marine-layer mornings add condensation concerns inside older wall cavities. The Hillside areas introduce another variable: pier-and-beam foundations and sloped, irregular attics that make standard batt installs a poor fit. The job here is less about upgrading R-value and more about sealing leaky envelopes without gutting historic plaster.
Our Main Hollywood Services
Most Hollywood homeowners start with one of two services: attic insulation or spray foam. Both address the city’s most common comfort problem, but they work differently depending on your roof type, wall structure, and budget.
Attic Insulation in Hollywood
Attics in Hollywood run the full range: flat-roofed courtyard buildings with barely any crawl space, sloped Hillside attics with irregular joist spacing, and classic bungalow attics that are more storage than conditioned space. We assess your ceiling structure and roof deck before recommending blown-in fiberglass or cellulose. Flat-roof buildings need special attention because the roof deck sits directly above the living space, and unvented assemblies trap heat. Learn more about your options on our Attic Insulation in Hollywood page.
Spray Foam Insulation in Hollywood
Older Hollywood homes with unsealed wall cavities and roof decks that radiate heat into living areas often benefit most from spray foam. Closed-cell foam air-seals and insulates in one pass, which matters when you’re dealing with balloon-frame construction and original plaster that you don’t want to remove. We install open- and closed-cell foam through Icynene and Demilec, two brands most general contractors in Hollywood don’t carry. See the full breakdown on our Spray Foam Insulation in Hollywood page.

Blown In Insulation in Hollywood
Blown in insulation is the most practical solution for most Hollywood homes built before 1960. Dense-packed cellulose or loose-fill fiberglass fills wall cavities and attic floors without tearing out original lath-and-plaster, which matters in a city where preserving 1920s and 1930s character is part of the property’s value. In flat-roofed courtyard apartments, blown-in attic insulation sits directly above the ceiling and stops the roof deck from radiating August heat into top-floor units. Blown In Insulation is the core of what we do at Fountain Valley Insulation, and Hollywood’s housing stock is exactly what it was developed for.
Cellulose Insulation
Signs you need it
Rooms that heat up by mid-morning, even with the AC running, and original walls that feel hollow when you knock on them.
What it costs in Hollywood
Blown-in cellulose for an average Hollywood attic or wall cavity typically runs $1.10-$1.80 per square foot installed.
How we do it
We run a hose into the wall cavity or attic space through small access holes, dense-pack the material, and patch the holes cleanly.
Blown In Attic Insulation
Signs you need it
Top-floor rooms that stay hot well after sunset, or an attic that reads hotter than the outside air on a summer afternoon.
What it costs in Hollywood
Blown-in attic insulation in Hollywood typically runs $1.50-$2.50 per square foot installed, depending on depth and access.
How we do it
We blow loose-fill fiberglass or cellulose across the attic floor to the target depth, working around existing ductwork and wiring.
What Blown In Insulation Costs in Hollywood
| Item | Typical range in Hollywood |
|---|---|
| Blown-in cellulose (walls) | $1.10-$1.80 per sq ft |
| Blown-in fiberglass (attic floor) | $1.50-$2.50 per sq ft |
| Loose-fill attic (existing home, standard access) | $1,500-$3,000 total |
How long does blown in insulation last in Hollywood’s heat?
Cellulose and fiberglass both hold up well in Hollywood’s hot, dry climate. Expect 20-30 years of effective performance, though settling can reduce attic R-value over time and may call for a top-up.
Can you blow insulation into walls without removing the plaster?
Yes. We drill small access holes in the exterior or interior wall surface, dense-pack the material into the cavity, and patch the holes. Your original 1920s plaster stays intact. Call (833) 390-3099 for a free estimate.

What Hollywood Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
