Insulation Company in Beverly Hills, CA
Blown in insulation is the most common retrofit we perform in Beverly Hills, and for good reason: the city’s 1920s-1950s Spanish Colonial and ranch homes were rarely built with meaningful attic insulation, and their original plaster walls and clay-tile roofs make many other insulation methods impractical. Thermal Insulation Co has served Beverly Hills since 2012, focusing exclusively on insulation work – attic, blown-in, and spray foam – across ZIP codes 90210, 90212, 90213, and 90209. When cooling costs climb through August and Santa Ana winds push hot, dry air across the flats, the fix usually starts in the attic. Call (855) 382-3451 for a free estimate.
Why Beverly Hills Homes Are Different
Beverly Hills insulation work is dominated by mid-century ranch and Spanish Colonial homes being retrofitted for modern energy codes while preserving original plaster, custom millwork, and historic exterior profiles. That constraint matters. You cannot simply cut large access holes into a 1930s Spanish Colonial ceiling with decorative beams and expect the design review process to go smoothly. Much of our work here involves open-cell spray foam or blown-in cellulose executed in occupied, high-value homes where dust, overspray, and attic access through finished closets are deal-breakers.
The city’s own building standards and design review culture mean insulation upgrades frequently get folded into larger permitted remodels rather than done as standalone jobs. We coordinate with general contractors on those projects regularly. Many older homes on the flats still have uninsulated knob-and-tube-era attics, clay-tile roofs with minimal clearance, and original interior plaster that complicates blown-in and foam injection work. The Mediterranean climate – mild wet winters, long dry summers – means cooling loads and attic radiant heat matter more than heating, and fire-resistance at vents and eaves is a real consideration in the hillside areas north of Sunset.
Our Main Beverly Hills Services
Beverly Hills homeowners call us most about two services: attic insulation retrofits for older homes, and spray foam for new construction or hard-to-reach cavities. Here is what each involves locally.
Attic Insulation in Beverly Hills
Most pre-1960 Beverly Hills homes have attic insulation that is either missing entirely or compressed to a fraction of its original R-value. Clay-tile and slate roofs on flats and hillside estates leave almost no attic crawl clearance, so crews routinely do injection-foam and dense-pack work from the exterior through tile lifts rather than from inside. We assess the existing attic, check for knob-and-tube wiring that must be addressed first, then recommend the right material for the home’s roof profile and access constraints. Learn more about Attic Insulation in Beverly Hills.
Spray Foam Insulation in Beverly Hills
Spray foam solves problems other materials cannot in Beverly Hills: closed-cell foam adds structural rigidity to older roof decks, open-cell foam fills irregular cavities in Spanish Colonial eaves, and both air-seal against Santa Ana dust intrusion. For hillside homes north of Sunset, closed-cell foam at vents and eaves also improves ember resistance. We install both open-cell and closed-cell systems using Icynene and Demilec products. See Spray Foam Insulation in Beverly Hills for specifics.

Blown In Insulation in Beverly Hills
Blown in insulation – typically loose-fill fiberglass or cellulose installed with a pneumatic blower – is the workhorse retrofit for Beverly Hills attics built before 1960. Those homes rarely have enough attic clearance for batt installation, and the plaster ceilings below cannot tolerate aggressive maneuvering from above. Blown-in material flows around existing framing, settles into irregular cavities, and can be installed through small access points without disturbing finished living spaces. For occupied, high-value homes where dust and disruption are deal-breakers, blown-in cellulose from GreenFiber offers a recycled-content option that performs well in our Mediterranean climate’s long cooling season. Thermal Insulation Co installs blown-in insulation across Beverly Hills as one of our three core methods – batts, blown-in, and spray foam – and we will tell you which actually makes sense for your home. Visit our Blown In Insulation page for the full method breakdown.
Cellulose Insulation
Signs you need it
Your Beverly Hills home’s attic has less than 6 inches of old, settled insulation, or your upstairs rooms run 8-10 degrees warmer than downstairs from June through October.
What it costs in Beverly Hills
Blown-in cellulose in a typical Beverly Hills attic runs $1,800 to $3,500 depending on square footage and target R-value.
How we do it
We air-seal penetrations first, then blow GreenFiber cellulose through a hose run from the exterior or a small interior access point, building to the R-value your home’s ceiling assembly calls for.
Blown In Attic Insulation
Signs you need it
Your energy bills spike from May through September, or you can see the top of your ceiling joists when you peer into the attic.
What it costs in Beverly Hills
Blown-in attic insulation in Beverly Hills typically falls between $1,800 and $4,200 for fiberglass or cellulose across a standard 1,500-2,500 square foot attic.
How we do it
We measure existing R-value, check for gaps around recessed lights and vent penetrations, then blow loose-fill insulation to a consistent, code-appropriate depth across the full attic floor.
Blown In Cellulose Insulation
Signs you need it
You want a denser, quieter attic insulation that resists air movement better than fiberglass, especially in an older Beverly Hills home with irregular rafter spacing.
What it costs in Beverly Hills
Dense-pack cellulose in Beverly Hills walls or sloped ceilings runs $2,200 to $4,800, with the higher end reflecting tile-roof access work.
How we do it
We dense-pack GreenFiber cellulose into enclosed cavities at controlled pressure, which fills fully without settling and provides real air-sealing benefit.
What Blown In Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blown-in cellulose attic (1,500-2,000 sq ft) | $1,800 – $3,500 |
| Blown-in fiberglass attic (1,500-2,000 sq ft) | $1,600 – $3,200 |
| Dense-pack cellulose in walls or sloped ceilings | $2,200 – $4,800 |
Does blown in insulation work in older Beverly Hills attics?
Yes, blown-in insulation is often the best fit for pre-1960 Beverly Hills homes because it conforms to irregular framing and goes in through small access points without cutting into original plaster. Call (855) 382-3451 to schedule an attic assessment.
Is cellulose or fiberglass better for Beverly Hills cooling loads?
Cellulose typically performs better in high-heat conditions because its density slows air movement more effectively than loose-fill fiberglass, which matters during Beverly Hills’ long dry summers. We stock both so we can recommend based on your actual attic.

FAQs About Insulation Company in Beverly Hills
Most Beverly Hills projects start within one to two weeks of the estimate, depending on material availability and any permitting coordination needed for hillside properties. Free estimates are usually scheduled within one to two business days. Call (855) 382-3451 to check current availability.
For a straightforward attic insulation upgrade in an existing home, permits are generally not required. If the insulation is part of a larger remodel or involves structural changes, your general contractor’s permit will typically cover it. We can advise you during the estimate based on your project’s scope.
Yes. Blown-in insulation and injection foam are specifically chosen for older Beverly Hills homes because both methods work from the attic side or through small exterior access points, leaving original plaster ceilings and walls untouched. This is a big reason we carry multiple installation methods under one roof.

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."
— Maya Singh"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."
— Christine Park"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
