Insulation in Beverly Hills, CA
Spray foam insulation in Beverly Hills is the highest-demand retrofit because so many Trousdale Estates and hillside homes were built in the 1950s and 1960s with zero insulation between the ceiling and the flat roof deck. Closed-cell foam applied to the underside of that roof deck adds R-value, vapor control, and structural strength without raising the roofline that Beverly Hills zoning protects. Call (424) 955-2557 for a straight answer on your home.
Why Beverly Hills Homes Are Different
The city splits into two distinct housing zones, and each one fails thermally in its own way. South of Santa Monica Blvd, the 1920s through 1940s Spanish Colonial and Tudor homes often still have original horsehair or no insulation inside plaster-on-lath walls. North of Sunset, the post-WWII estates, particularly the Trousdale Estates tract, were built with flat roofs, open-plan interiors, and floor-to-ceiling glass walls that were never designed with thermal performance in mind.
The hillside canyons, Benedict, Coldwater, and the Trousdale bench, create intense afternoon radiant heat gain in summer while channeling cool canyon air at night. That produces a wider daily temperature swing than the LA basin flats a few miles south, which means attic and roof-deck insulation works harder here. Santa Ana wind events then drive rapid heating through those poorly insulated flat roofs each fall. And every insulation job in Beverly Hills must pass through the city’s own independent building department, separate from LADBS, which enforces Title 24 compliance on its own timeline and permit process. We handle that paperwork. You shouldn’t have to.
Our Main Beverly Hills Services
Most Beverly Hills homeowners call us first about two things: attics that bake the second story all summer, and crawl spaces that smell damp and musty. These two services have their own dedicated pages here.
Attic Insulation in Beverly Hills
In Beverly Hills, attic insulation works hardest on the flat-roofed homes north of Sunset where the original roof assembly offers almost no thermal break. On a 1950s Trousdale home, we often find a thin wood or concrete deck exposed to full sun, plywood directly above it, and nothing else. That turns the attic into a heat battery. Attic Insulation in Beverly Hills covers what we typically find in these attics and how we fix them without disturbing original architectural finishes.
Crawl Space Encapsulation & Vapor Barrier in Beverly Hills
Older Beverly Hills homes in the flats south of Santa Monica Blvd sit on vented crawl spaces that pull moisture and air upward through the house, carrying whatever is down there into the living space. A sealed, vapor-barrier-lined crawl space changes that. Crawl Space Encapsulation & Vapor Barrier in Beverly Hills walks through the process, cost, and what you can expect in a 1920s-era home here.

Spray Foam Insulation in Beverly Hills
Spray foam insulation in Beverly Hills solves the core problem with mid-century flat-roof construction: there is no cavity to fill, only a roof deck sitting in full sun. Closed-cell Spray Foam Insulation applied to the underside of that deck adds structure, vapor control, and R-value in a single pass, without raising the roofline. Contractors working Trousdale Estates quickly learn the original 1950s and 1960s homes often have no insulation whatsoever between the interior ceiling and the roofing membrane, just a thin concrete or wood deck. Closed-cell foam is now the go-to solution because it does what nothing else can in that tight assembly.
Closed-Cell Spray Foam
Signs you need it
Your upstairs rooms get noticeably hotter than downstairs by late afternoon, and the ceiling feels warm to the touch even after sunset.
What it costs in Beverly Hills
Closed-cell spray foam on a roof deck in Beverly Hills typically runs $3.00-$7.00 per board foot, depending on depth and access inside the attic.
How we do it
We prep the attic, protect finished surfaces, spray directly against the roof deck in passes to hit the specified depth, then trim and inspect the finished surface.
Spray Foam Roof Deck
Signs you need it
You have a flat or low-slope roof, the attic is blistering in summer, and roofers have told you there’s no cavity insulation to upgrade.
What it costs in Beverly Hills
Full spray foam roof deck application in Beverly Hills falls between $4,000 and $12,000, with most mid-century homes landing in the middle of that range.
How we do it
We mask and protect the interior, spray closed-cell foam to a uniform depth on the deck underside, and seal any penetrations as part of the same pass.
What Spray Foam Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Open-cell spray foam (per board foot) | $0.50 - $2.00 |
| Closed-cell spray foam (per board foot) | $3.00 - $7.00 |
| Spray foam roof deck (full job) | $4,000 - $12,000 |
Is closed-cell foam worth the higher cost in Beverly Hills?
Yes, for flat-roof mid-century homes with no cavity insulation. Closed-cell adds structural rigidity and vapor control to an uninsulated roof deck, which no fiberglass or cellulose product can match in that assembly.
Can you spray foam a Beverly Hills attic without touching original finishes?
We mask floors, trim, and built-ins before spraying, and our crew is used to working inside high-value mid-century homes where original millwork cannot be replaced. Surfaces stay fully protected.
Blown-In Insulation in Beverly Hills
Blown-in insulation in Beverly Hills is the standard upgrade for homes with vented attics that have some existing insulation but not nearly enough for the hillside’s wide daily temperature swings. On a 1950s estate north of Sunset, we routinely find two or three inches of settled fiberglass under a roof that absorbs full afternoon sun. Blown-In Insulation gets you to the R-value the city’s climate actually demands, fast, without opening walls or disturbing finished interiors.
Blown-In Cellulose
Signs you need it
Your attic has bare spots or thin, settled insulation, and you can feel heat moving through the ceiling by mid-afternoon.
What it costs in Beverly Hills
Blown-in cellulose in a Beverly Hills attic typically runs $0.90-$2.10 per square foot, including the prep and cleanup.
How we do it
We air-seal the attic floor first, then blow GreenFiber cellulose to the specified depth, fluffing it level across the entire space.
Dense-Pack Wall Insulation
Signs you need it
Your 1920s or 1930s home has hollow plaster-on-lath walls and the rooms feel drafty even with the heat on.
What it costs in Beverly Hills
Dense-pack wall insulation in Beverly Hills runs $2.50-$5.00 per square foot of wall area, depending on how many penetrations are needed.
How we do it
We drill small access holes through the plaster or siding, blow cellulose under pressure at the right density, then patch and touch up.
What Blown-In Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blown-in cellulose (per sq ft) | $0.90 - $2.10 |
| Blown-in fiberglass (per sq ft) | $1.50 - $3.50 |
| Dense-pack wall insulation (per sq ft of wall) | $2.50 - $5.00 |
Is blown-in insulation enough for a Beverly Hills flat roof?
Only if the attic is vented with a real air space above. For unvented flat decks with no cavity, spray foam is the right call, blown-in won’t do the job there.
How long does blown-in attic insulation last here?
Cellulose keeps performing for 20 to 30 years in this climate, but Santa Ana heat and attic moisture can settle it in the first few years, so air sealing first matters. Call for an honest read on yours.
Radiant Barrier Installation in Beverly Hills
Radiant barrier installation in Beverly Hills attacks the intense afternoon radiant heat that hillside canyons like Benedict and Coldwater channel straight onto the roof. That heat radiates down through the roof assembly into the living space even when the attic air temperature is tolerable. Radiant Barrier Installation puts a low-emissivity surface between your roof deck and your living space, which is the single most cost-effective upgrade for cooling-season comfort on these mid-century flat roofs.
Attic Radiant Barrier
Signs you need it
Your ceiling feels warm to the touch by 3pm on summer days, even with attic insulation present.
What it costs in Beverly Hills
Attic radiant barrier in a Beverly Hills home runs $1.50-$3.00 per square foot installed, depending on rafter configuration.
How we do it
We staple aluminum-faced barrier to the underside of the rafters, leaving an air gap that’s required for it to reject radiant heat properly.
Radiant Barrier Roof Deck
Signs you need it
You have a flat-roof mid-century home where the deck itself radiates heat downward, and you want to cut heat gain without adding bulk.
What it costs in Beverly Hills
Roof-deck radiant barrier in Beverly Hills runs $2,000-$5,500 for a typical flat roof, depending on access and deck area.
How we do it
We install barrier directly under the deck surface or on top of existing insulation, keeping the required air gap so the foil can do its job.
What Radiant Barrier Installation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic radiant barrier (per sq ft) | $1.50 - $3.00 |
| Roof deck radiant barrier (full job) | $2,000 - $5,500 |
| Radiant barrier plus ventilation upgrade | $3,000 - $7,500 |
Does a radiant barrier make sense in a mild coastal climate like this?
Beverly Hills sits far enough inland that canyon exposure creates real radiant heat gain. If your ceiling gets hot to the touch in summer, a radiant barrier helps noticeably, especially under flat roofs.
Will a radiant barrier alone fix my hot upstairs?
It reduces radiant heat gain, but for a 1950s uninsulated roof deck you’ll generally pair it with spray foam or proper attic insulation to actually fix the temperature problem.
Insulation Removal & Replacement in Beverly Hills
Insulation removal and replacement in Beverly Hills usually starts because of one of two things: rodent contamination in an older flat-roof attic, or old vermiculite that predates any safety testing. In a 1920s Spanish Colonial in the flats, you may be the first person to open that attic in thirty years, and what’s up there often isn’t doing its job anymore. Insulation Removal & Replacement clears the old material out completely so the new layer can perform correctly.
Contaminated Insulation Removal
Signs you need it
You smell a persistent mustiness from the ceiling, or you have seen rodent droppings in the attic. Insulation holding that waste has to go.
What it costs in Beverly Hills
Contaminated insulation removal in a Beverly Hills attic runs $2.00-$4.50 per square foot, including the removal and disposal.
How we do it
We vacuum the old material out with a commercial HEPA rig, bag it, sanitize the attic, and haul everything away. We never leave it in your yard.
Vermiculite & Old Insulation Removal
Signs you need it
Your pre-1960s attic contains grayish, pebble-like vermiculite, a material that can contain asbestos and should never be disturbed casually.
What it costs in Beverly Hills
Vermiculite or old insulation removal in Beverly Hills typically runs $3,000-$8,000, given the containment and testing protocols involved.
How we do it
We take samples for testing if needed, then remove under controlled containment so neither your family nor our crew breathes the material.
What Insulation Removal & Replacement Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic insulation removal (per sq ft) | $1.50 - $3.50 |
| Contaminated insulation removal (per sq ft) | $2.00 - $4.50 |
| Vermiculite or asbestos-pattern old insulation removal | $3,000 - $8,000 |
How do I know if my Beverly Hills attic has vermiculite?
Look for small, shiny, gray-brown pebbles under newer insulation. If you see it, don’t disturb it. Call us, we’ll test before anyone goes up there.
Do you remove insulation the same day in Beverly Hills?
Most attics are removed in a single day, then we can schedule the new installation for the next day or the same visit depending on the job. Call (424) 955-2557 for a time estimate.
Attic Air Sealing in Beverly Hills
Attic air sealing in Beverly Hills matters because the stack effect pulls air up through your house and out the attic, and in the canyons that means hot air replacing cool conditioned air all afternoon. The flats-era homes South of Santa Monica Blvd are especially leaky around plaster cracks, recessed lights, and the attic hatch. Attic Air Sealing stops that air movement before you add insulation, because insulation cannot do its job when air is blowing through it.
Attic Floor Air Sealing
Signs you need it
Your air conditioning runs constantly in summer, yet the upstairs still feels muggy and you feel drafts near the attic hatch.
What it costs in Beverly Hills
Attic floor air sealing in Beverly Hills runs $1.50-$3.50 per square foot, which is the single best efficiency dollar most homes here will spend.
How we do it
We move insulation aside, seal every seam and penetration in the attic floor with foam or caulk, then put the insulation back in place.
Can Light & Duct Boot Sealing
Signs you need it
You have old recessed can lights that get hot, and you can feel air moving around them when you stand underneath.
What it costs in Beverly Hills
Sealing can lights and duct boots in a Beverly Hills home runs $300-$1,200, depending on how many penetrations need covers and sealing.
How we do it
We install fire-rated covers over each can from the attic side, seal the foam around the edges, then seal every duct boot connection.
What Attic Air Sealing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic floor air sealing (per sq ft) | $1.50 - $3.50 |
| Can light sealing (per fixture) | $25 - $75 |
| Full attic air sealing (typical 2,000 sq ft attic) | $3,000 - $7,000 |
Do I need air sealing before adding insulation in Beverly Hills?
Yes. Insulation cannot stop air movement, only heat transfer. Sealing first means the insulation you then add actually performs at its rated R-value.
Will air sealing mess up my 1920s plaster ceiling?
No. We work from the attic side, so the ceiling itself stays untouched. We protect finished surfaces and clean up fully after the job.
Wall Insulation in Beverly Hills
Wall insulation in Beverly Hills is most needed in the 1920s through 1940s homes south of Santa Monica Blvd, where hollow plaster-on-lath walls have almost no thermal resistance. But the hillside estates need wall work too, especially when owners are building home theaters or wine cellars and want interior sound control between rooms. Wall Insulation covers the retrofit approach, and in most older Beverly Hills homes it’s done from the exterior or through small penetrations, not by opening up plaster walls.
Injection Foam Wall Insulation
Signs you need it
Your walls are hollow when you knock on them, and rooms near the exterior wall get cold quickly once the heat turns off.
What it costs in Beverly Hills
Injection foam wall insulation in Beverly Hills runs $2.50-$5.00 per square foot of wall area, with plaster-era homes trending toward the high end.
How we do it
We drill small holes at stud-bay level, inject foam that conforms around existing lath and wiring, then patch the holes to match.
Interior Wall Soundproofing
Signs you need it
You hear conversation from the next room through the wall, or you’re building a home theater or wine cellar and want real acoustic separation.
What it costs in Beverly Hills
Interior wall soundproofing in Beverly Hills runs $2.00-$6.00 per square foot, depending on whether you want foam, dense-pack fiberglass, or mineral wool.
How we do it
We dense-pack the wall cavities with Rockwool or fiberglass at the correct density, which adds both thermal mass and acoustic damping.
What Wall Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Injection foam wall insulation (per sq ft) | $2.50 - $5.00 |
| Drill & fill wall insulation (per sq ft) | $2.00 - $4.50 |
| Interior wall soundproofing (per sq ft) | $2.00 - $6.00 |
Can you insulate my 1920s walls without destroying the plaster?
Yes. We drill from the exterior or through discreet interior points, inject or blow insulation into the cavities, then patch while preserving the original plaster and lath.
Will wall insulation help with noise between rooms in a Beverly Hills estate?
Dense-packed mineral wool or cellulose makes a real difference in interior sound transfer, which is why it’s our go-to for home theater and wine cellar builds.
Attic Cleaning & Rodent Proofing in Beverly Hills
Attic cleaning and rodent proofing in Beverly Hills goes beyond basic cleanup, because the hillside canyons and older flat-roof construction give rodents reliable entry points and plenty of nesting material. Insulation that has been used as a bathroom is a health issue and a performance problem. Attic Cleaning & Rodent Proofing removes the contaminated material, sanitizes the deck, and seals every opening so they cannot come back.
Attic Cleanout
Signs you need it
You hear scratching at night, or you have been up in the attic and seen droppings, nesting, or chewed insulation.
What it costs in Beverly Hills
A full attic cleanout in Beverly Hills runs $1,200-$3,500, depending on attic size and how long the rodents have been working.
How we do it
We vacuum out all contaminated insulation and debris, bag it for disposal, then wash down the deck surface before any new material goes in.
Rodent Proofing & Exclusion
Signs you need it
You have fixed the visible rodent problem but they keep coming back, or a new attic smell returns within weeks of cleaning.
What it costs in Beverly Hills
Rodent proofing and exclusion on a Beverly Hills home runs $800-$3,000, depending on how many entry points need sealing.
How we do it
We work the roofline, vents, and gaps around pipes and conduits, sealing every point a rodent can fit through with materials they cannot chew through.
What Attic Cleaning & Rodent Proofing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic cleanout | $1,200 - $3,500 |
| Attic sanitizing & decontamination | $600 - $1,800 |
| Rodent proofing & exclusion | $800 - $3,000 |
How do rodents get into a Beverly Hills flat roof attic?
Through the gaps where flat roof flashing meets parapet walls, around plumbing vents, and under loose eave gaps. We find the same handful of entry points on nearly every mid-century home here.
Can you clean my attic the same week I call?
Most Beverly Hills attic cleanouts are scheduled within a few days. Call (424) 955-2557 and we’ll give you a straight answer on timing and cost.
Home Energy Audit in Beverly Hills
A home energy audit in Beverly Hills is the fastest way to know whether your money should go into the roof deck, the walls, the attic floor, or the crawl space, before you spend on any of them. The hillside homes here have so many competing issues that guessing wrong is expensive. Home Energy Audit uses blower door and thermal imaging to find exactly where the house is losing conditioned air, and we give you a written report that ranks the fixes by payback.
Blower Door Test
Signs you need it
Your energy bills keep climbing and you need to know whether air leakage or missing insulation is the bigger problem.
What it costs in Beverly Hills
A blower door test as part of a Beverly Hills energy audit runs $300-$600, and it’s the core of the whole assessment.
How we do it
We mount a calibrated fan in the front door, depressurize the house, and measure exactly how many air changes per hour the building leaks.
Thermal Imaging Inspection
Signs you need it
Specific rooms stay cold or hot no matter what the thermostat says, and you want to see the missing insulation, not guess at it.
What it costs in Beverly Hills
Thermal imaging as part of a full home audit runs $200-$450, depending on house size and the number of images captured.
How we do it
We scan every room’s walls and ceilings with an infrared camera, documenting exactly where insulation is missing, thin, or wet.
What Home Energy Audit Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blower door test | $300 - $600 |
| Thermal imaging inspection | $200 - $450 |
| Full home energy audit with report | $500 - $1,500 |
Is a home energy audit worth it before a big Beverly Hills renovation?
Always. On mid-century and Spanish-era homes here, an audit regularly finds that the roof deck or crawl space, not the windows, is the real problem, which reshapes the whole renovation budget.
Do you give the audit report to me, or keep it?
You get the full written report with images and a ranked list of fixes. We’re happy to do none, some, or all of the work afterward.

What Beverly Hills Customers Say
"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
- Nadia Haddad"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
- Linda Baumgartner"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
