Insulation Company in Beverly Hills, CA
Blown in insulation solves the single most common problem we see in Beverly Hills homes: attic spaces and wall cavities that were built before insulation was standard practice. The 1920s and 1930s Spanish Colonial homes on the flats, and the custom hillside estates above Sunset, both run hot in summer and cool down fast on winter nights. We’re Hollywood Insulation Co, a dedicated insulation specialist working across 90210, 90212, and the surrounding Beverly Hills ZIP codes. Call (866) 605-6949 for a free estimate.
Why Beverly Hills Homes Are Different
Beverly Hills sits in a warm inland pocket that routinely runs 10 to 15 degrees hotter than Santa Monica or the coastal Westside. That means attic temperatures here climb higher, cooling loads are heavier, and the payoff from properly installed insulation is bigger than in beach-adjacent cities. The housing stock compounds the challenge. Many flat-street homes built between the 1920s and 1950s still have original frame walls and empty or barely-insulated attics, even after cosmetic renovations.
Above Sunset Boulevard, the terrain changes the job entirely. Hillside estates face canyon wind exposure, and the city’s wildfire-conscious construction expectations mean insulation in vented attics and eave areas often needs to be non-combustible. Rockwool mineral wool gets specified here where a contractor from the flats would default to fiberglass batts. Complex roof geometries on multi-level custom homes also make insulation detailing closer to commercial work than a standard residential install.
Our Main Beverly Hills Services
Beverly Hills homeowners call us most often about two services: attic insulation and spray foam insulation. Both address the heat, the energy bills, and the comfort issues that come with this city’s older housing stock and hot inland climate.
Attic Insulation in Beverly Hills
Attic temperatures in Beverly Hills climb fast, especially on the flat streets where the sun hits hard from mid-morning through late afternoon. An under-insulated attic pushes that heat down into living spaces and forces HVAC systems to run constantly. We install high-R ceiling insulation, radiant barriers, and proper ventilation tailored to the home’s specific roofline. Whether it’s a 1920s Spanish Colonial or a modern gut-renovation, the job starts with a full assessment of what’s currently up there. Learn more on our Attic Insulation in Beverly Hills page.
Spray Foam Insulation in Beverly Hills
Hillside estates above Sunset often have exposed framing, irregular cavities, and rooflines that standard batts can’t seal properly. Spray foam handles those gaps and creates a tighter building envelope, cutting both air leakage and cooling costs. We install both open-cell and closed-cell systems, including Icynene and Demilec, matched to the specific application whether that’s a vented attic needing air sealing or a cathedral ceiling with limited cavity depth.

Blown In Insulation in Beverly Hills
Blown in insulation is the most practical retrofit option for most Beverly Hills homes, especially the 1920s through 1950s construction on the flats that was never insulated properly in the first place. Loose fill material gets blown into attic floors and wall cavities through small access points, filling gaps and covering irregular spaces that batts leave exposed. In a climate that runs 10 to 15 degrees hotter than the coast, that coverage directly translates to lower cooling bills and more even room temperatures, which is why we recommend it so often for older Beverly Hills houses. For a deeper look at the method itself, see our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
You can see the attic floor joists through a thin layer of old insulation, or rooms directly under the attic get noticeably warmer than the rest of the house by mid-afternoon.
What it costs in Beverly Hills
Blown in cellulose for a typical Beverly Hills attic runs $1.75 to $3.10 per square foot installed, depending on the depth required and access conditions.
How we do it
We dense-pack or loose-fill GreenFiber recycled cellulose to the required R-value, working around existing wiring, recessed lights, and vent baffles as we go.
Blown In Attic Insulation
Signs you need it
Your cooling bills spike every summer while upstairs rooms stay uncomfortable, or you find old insulation has settled to half its original depth.
What it costs in Beverly Hills
Blown in attic insulation across Beverly Hills typically falls between $1,800 and $4,200 for a full attic, depending on square footage and target R-value.
How we do it
We air-seal the attic floor penetrations first, then blow loose fill to a consistent depth that meets or exceeds current California energy code for this climate zone.
What Blown In Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blown in cellulose (attic) | $1.75 – $3.10 per sq ft |
| Blown in fiberglass (attic) | $1.60 – $2.90 per sq ft |
| Full attic blown in insulation | $1,800 – $4,200 |
Hillside access, high ceilings, and the need to work around original knob-and-tube wiring push costs toward the upper end of these ranges. We give an upfront price before any material leaves the truck.
How long does blown in insulation last in Beverly Hills?
Cellulose typically holds its R-value for 20 to 30 years if kept dry, though settling can reduce ceiling coverage by a few percent after the first year. We factor that into the initial depth we install.
Can you install blown in insulation in an older Beverly Hills home without tearing out walls?
Yes. Blown in insulation is the standard retrofit method for the 1920s-to-1950s frame homes across Beverly Hills. We access wall cavities through small exterior or interior openings and patch them cleanly afterward.
Brands We Service in Beverly Hills
We install products from eight manufacturer brands, and we stock the materials Beverly Hills projects actually need: Icynene and Demilec spray foam systems, Rockwool mineral wool, GreenFiber cellulose, and CertainTeed fiberglass among them. Having multiple brands in the lineup means the recommendation is based on what your home needs, not what happens to be on the truck. See our brands for the full range.

FAQs About Insulation Company in Beverly Hills
In most cases, no. Adding or upgrading insulation in an existing home’s attic or walls is typically handled without a city permit as long as no structural changes are involved. If your project includes opening walls or altering rooflines, the city’s building department may require plans, and we coordinate that with your contractor.
We schedule most Beverly Hills appointments within two to four business days, with faster turnaround available during slower seasons. Since we’re based in Hollywood, travel time to the flats or the hillside streets is short, and we keep our daily schedule structured around the Westside.
Yes, and we treat those projects differently than flat-street homes. Hillside estates in the canyons above Sunset often need non-combustible insulation in vented attics and eave areas due to wildfire exposure, plus careful handling on steep lots. We plan the material and access around those conditions from the first visit.

What Beverly Hills Customers Say
"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"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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
