Insulation Company in Hollywood, CA
Blown in insulation is the most common fix we recommend for Hollywood homes built before 1980, because most of them have thin, settled, or missing attic insulation and no practical way to add batts without tearing into original ceilings. The job usually takes one day and involves dense-packing or loose-fill material into attic floors and wall cavities from small access points. North Tustin Insulation has served Hollywood since 2011, working on historic bungalows, courtyard apartments, and hillside homes across 90028.

Why Hollywood Homes Are Different
Hollywood’s residential building stock skews heavily toward 1920s and 1930s bungalows, Spanish Colonial courtyards, and Craftsman-era apartments, with a second wave of 1960s and 1970s low-rise buildings filling in the flatlands below Franklin Avenue and around Santa Monica Boulevard. Most of these homes predate California’s first meaningful energy codes, so wall cavities are often empty and attic insulation is either nonexistent or reduced to a thin layer of dust. Low-pitch roofs and flat roof decks leave very little attic cavity to work in, which changes how we approach blown in insulation in Hollywood. A standard loose-fill job in a 1930s bungalow near Whitley Heights looks nothing like a job in a newer tract home. Tight, zero-lot-line lots mean access is often through a hallway closet or a small ceiling hatch rather than a full attic entry. And because so much of Hollywood sits within or adjacent to historic districts, the work has to be done without disturbing original lath-and-plaster ceilings, decorative beams, or period vents. Solar gain through old uninsulated roofs is the single biggest driver of uneven temperatures here, even with the mild coastal climate. Wildfire smoke events during dry summers have also pushed more Hollywood homeowners toward air sealing and insulation that keeps outdoor particulates from drifting through gaps in old framing.
Our Main Hollywood Services
Most Hollywood homeowners call us about two things: insulation in the attic, and spray foam for hard-to-reach or unvented spaces. Here’s how each one works in this city’s housing stock.
Attic Insulation in Hollywood
Old Hollywood bungalows and courtyard apartments lose most of their conditioned air through the attic, especially when roofs are low-pitch and the attic cavity is only eighteen to twenty-four inches deep. We air-seal the attic floor first, then install the right insulation material for the space, whether that is blown-in fiberglass, cellulose, or mineral wool batts. In hillside areas around Beachwood Canyon and the Hollywood Hills, we often find vented crawlspaces and underfloor cavities that need a completely different approach than a flatland attic. See the full breakdown on Attic Insulation in Hollywood.

Spray Foam Insulation in Hollywood
Flat-roof apartment buildings and 1960s low-rise structures in Hollywood often have no usable attic cavity at all, which makes spray foam the only realistic option for adding insulation without a major roof rebuild. We install open-cell foam in vented spaces and closed-cell foam where moisture control or structural strength matters. The same approach works well for rim joists and crawlspace walls in hillside bungalows. Read more on Spray Foam Insulation in Hollywood.

Blown In Insulation in Hollywood
Blown in insulation is the workhorse solution for Hollywood’s older homes because it fills irregular cavities without opening walls or ceilings. In 1920s and 1930s bungalows, the framing is often non-standard, the cavities are shallow, and the plaster is fragile, so installing batts means demolition. Blown in insulation goes in through small holes and settles into every gap, which makes it the most practical way to add real thermal performance to a Hollywood home without changing its character. It is also the fastest way to cut solar gain through old roofs during hot, dry summers and reduce how much wildfire smoke gets pulled into living spaces through gaps in old framing. We match the material to your home, not the other way around. For a deeper look at the method, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, gray, or dusty, and rooms heat up unevenly even though your HVAC system runs constantly.
What it costs in Hollywood
Blown-in cellulose in Hollywood typically runs $1.50 to $3.25 per square foot installed, depending on cavity depth and access.
How we do it
We air-seal the attic floor, then dense-pack or loose-fill GreenFiber cellulose through a hose from the access point, building up to the R-value the space can hold.
Blown In Attic Insulation
Signs you need it
Your attic has less than six inches of insulation, or you can see the ceiling joists poking through what is there.
What it costs in Hollywood
Expect $1,800 to $4,200 for a full blown-in attic insulation job in a typical Hollywood bungalow or courtyard unit.
How we do it
We seal bypasses around wiring, plumbing, and recessed lights, then blow loose-fill material evenly across the attic floor to the specified depth.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are compressed, damp, or full of rodent debris, and the attic is too shallow for a clean batt replacement.
What it costs in Hollywood
Blown-in fiberglass in Hollywood usually falls between $1.80 and $4.00 per square foot, with flat-roof and tight-access jobs at the higher end.
How we do it
We run a fiberglass blowing system from the street or yard, feeding material through a hose to the attic, then level it to an even depth across the floor.
Loose Fill Insulation
Signs you need it
You have an attic with irregular joist spacing, odd framing, or a very low-slope roof that makes batt installation impractical.
What it costs in Hollywood
Loose fill insulation in Hollywood generally ranges from $1.50 to $3.75 per square foot installed, not including any air-sealing prep.
How we do it
We prep the space, install dams and baffles where needed, then blow the chosen loose-fill material to the target depth without compacting it.
What Blown In Insulation Costs in Hollywood
| Item | Typical range in Hollywood |
|---|---|
| Blown in cellulose (attic floor) | $1.50 – $3.25 per sq ft |
| Full attic blown-in job (bungalow/courtyard) | $1,800 – $4,200 |
| Blown in fiberglass (attic) | $1.80 – $4.00 per sq ft |
Is blown in insulation worth it in Hollywood’s mild climate?
Yes, because the problem here is solar gain, not extreme cold. An uninsulated attic in Hollywood can reach 130 degrees in summer, and that heat radiates down into rooms all evening. Blown in insulation drops the temperature delta fast.
Can you blow insulation into old Hollywood walls without gutting them?
Yes. We drill small access holes, dense-pack the cavity, and patch carefully so the original plaster and siding stay intact. Call (877) 265-5712 to find out if your wall framing will take dense-pack.

The biggest price movers in Hollywood are attic access and roof geometry. A flat-roof 1960s apartment with a two-foot attic cavity costs more to insulate than a Craftsman with a full attic stair. Tight zero-lot-line lots also mean we sometimes need to run hoses from the street, which adds a little labor. Every estimate is line-itemed and given before work starts, so you know the number before we begin.

FAQs About Insulation Company in Hollywood
Most Hollywood homes can be scheduled within a week of the estimate, and smaller blown-in attic jobs often fit into the same week. Hillside and flat-roof jobs may take an extra day or two for setup. Call (877) 265-5712 to check our current Hollywood schedule.
For most blown-in attic and wall insulation work, no permit is needed, but if your home is in a designated historic district, exterior wall access may trigger review. We check the property status before quoting so there are no surprises.

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."
— Ryan Rhodes"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Bethany Ziegler"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nathan Padgett
