Insulation Company in Hollywood, CA
Blown in insulation solves a problem Hollywood homeowners know well: walls and attics that were never insulated in the first place, or that have settled material leaving gaps heat pours through every summer. Fontana Insulation has served Hollywood since 2011, retrofitting 1920s courtyard apartments, mid-century stucco multifamily buildings, and bungalows across the flats with dense-pack cellulose and fiberglass. We carry eight insulation brands so the recommendation matches your wall cavities and budget, not our inventory. Call (866) 271-1602 for a free assessment.
Why Hollywood Homes Are Different
Hollywood’s housing stock creates retrofit challenges most suburban contractors never see. The 1920s courtyard apartments and bungalows that define the flats were built with wood framing, stucco exteriors, and wall cavities that are either empty or holding a thin layer of original material long since settled to uselessness. Many still have knob-and-tube wiring running through those cavities, which means blown-in insulation here requires a careful, code-conscious approach rather than a standard drill-and-fill job. Mid-century stucco-and-drywall multifamily buildings near the Boulevard present the opposite issue: adequate framing depth but almost no attention paid to air sealing when they went up.
The climate matters too. Hollywood gets long cooling seasons, mild winters, and occasional Santa Ana wind events that push dry heat through every unsealed penetration in a building envelope. Attic insulation here earns its keep against radiant sun on stucco and heat gain, not against freezing temperatures. That changes the calculation on R-value targets and material selection. And the sound issue can’t be overstated: with the 101 corridor, major surface streets, the Hollywood Bowl’s amplified season, and dense multifamily-and-tourist fabric packed together, many of our Hollywood clients specify insulation packages to cut noise transfer as much as cooling bills. That dual acoustic-plus-thermal brief doesn’t come up the same way in flatter, more suburban parts of LA.
Our Main Hollywood Services
Hollywood homeowners call on two services more than any other, and each addresses a different failure point in the local housing stock.
Attic Insulation in Hollywood
Attics in Hollywood’s older bungalows and courtyard apartments are usually the single biggest source of heat gain. The sun beats on stucco and roofing all day, and that heat radiates down through uninsulated attic floors into living spaces. Blown-in fiberglass or cellulose in the attic floor, paired with air sealing around penetrations, cuts that transfer significantly. In shared attic spaces common to older multifamily buildings, proper insulation also reduces sound flanking between units. Attic Insulation in Hollywood covers the full scope of this work.
Spray Foam Insulation in Hollywood
Where Hollywood homes need air sealing as much as insulation, spray foam is the right tool. Older wood-frame buildings with stucco exteriors leak air through rim joists, wall top plates, and around windows, and those leaks undermine any thermal improvement. Closed-cell spray foam air-seals and insulates in one pass, and it’s particularly useful in the higher-rise infill near the Boulevard where conditioned space meets hot ambient air. Spray Foam Insulation in Hollywood details material options and the applications where foam beats blankets or blown material.

Blown In Insulation in Hollywood
Blown in insulation in Hollywood is typically the most practical way to retrofit the empty or under-insulated wall cavities common in this city’s 1920s courtyard apartments and bungalows, because it can be installed through small access holes without gutting stucco exteriors or interior plaster. The dry, warm climate makes dense-pack cellulose and fiberglass effective against heat gain and radiant sun, while the material’s density also helps cut sound transfer through shared walls in multifamily buildings. Fontana Insulation has installed Blown In Insulation throughout Hollywood since 2011, and we carry multiple material options so the blow-in method matches your building’s framing and wiring conditions.
Cellulose Insulation
Signs you need it
Rooms that stay hot in the afternoon and cold at night despite running HVAC, especially in the stucco bungalows and courtyard apartments built before modern insulation standards, usually point to empty or settled wall cavities that dense-pack cellulose can fill.
What it costs in Hollywood
Dense-pack cellulose wall retrofit in Hollywood typically runs $1.50 to $3.50 per square foot of wall area, depending on cavity access and whether existing material must be removed first.
How we do it
We drill small access holes through stucco or drywall at each stud bay, dense-pack the cellulose to a consistent density that resists settling, then patch the holes flush so the original surface can be repainted.
Blown In Attic Insulation
Signs you need it
If your second floor or ceiling feels warm by mid-afternoon and your AC never seems to catch up, the attic floor likely has thin or missing insulation letting radiant heat pour down from the roof deck.
What it costs in Hollywood
Blown-in attic insulation in Hollywood typically costs $1.00 to $3.00 per square foot for the attic floor, including air sealing around penetrations where heat and Santa Ana dust enter.
How we do it
We seal the attic floor penetrations first, then blow loose-fill fiberglass or cellulose to the target R-value depth, keeping baffles clear at eaves so ventilation still works.
Blown In Fiberglass Insulation
Signs you need it
Open attics with visible joists and batts that have compressed, shifted, or been disturbed by old electrical work signal a good candidate for fresh blown-in fiberglass at a consistent depth.
What it costs in Hollywood
Blown-in fiberglass attic work in Hollywood generally falls between $1.00 and $2.25 per square foot, with dense-pack wall applications running higher at $2.00 to $4.00 per square foot depending on framing access.
How we do it
We run the blow hose across the attic floor in a controlled pattern, building up uniform thickness to the specified R-value, and we keep the material clear of recessed light housings and vent baffles.
What Blown In Insulation Costs in Hollywood
| Item | Typical range in Hollywood |
|---|---|
| Blown-in attic insulation | $1.00 – $3.00 per sq ft |
| Dense-pack cellulose wall retrofit | $1.50 – $3.50 per sq ft |
| Dense-pack fiberglass wall retrofit | $2.00 – $4.00 per sq ft |
Does blown in insulation actually cut noise between Hollywood apartment units?
Yes. Dense-pack cellulose and fiberglass both add mass inside shared wall cavities, which measurably reduces sound transfer through party walls and shared attics in Hollywood’s courtyard apartment buildings, especially where there was previously no insulation at all.
How long does blown in insulation take in a Hollywood bungalow?
Most Hollywood bungalow wall retrofits finish in one day, with attic work taking half a day to a full day depending on square footage and whether we’re removing old material first. Dense-pack jobs need extra time for patching access holes.

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."
— Michelle Bennett"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."
— Sarah Fletcher"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."
— Holly Mercer
