Insulation in Beverly Hills, CA
Spray foam insulation in Beverly Hills costs $1.50 to $4.50 per board foot installed, with most full-attic jobs landing between $3,000 and $9,000 depending on depth and access. The homes here, many built between the 1920s and 1960s, were framed before California’s Title 24 energy code existed, which means most carry far less insulation than current requirements. For the pre-war estates south of Sunset and the flat-roof mid-century homes in Trousdale Estates, the right insulation strategy has more to do with preserving architecture than just adding R-value.

Why Beverly Hills Homes Are Different
Beverly Hills’s housing stock skews heavily toward pre-WWII Spanish Colonial Revival, Tudor Revival, and Georgian Colonial estates constructed with original lath-and-plaster walls. Those walls often have zero cavity insulation. Homeowners here don’t call us for a simple top-up; they call during luxury gut-renovations, when the plaster comes down and the stud bays are finally exposed. Every permitted project must clear Beverly Hills’s own independent building department, not the City of Los Angeles’s, alongside California Title 24 compliance. That combination makes the permitting process more exacting and slower than in any surrounding jurisdiction.
The terrain matters too. The hillside neighborhoods north of Sunset, particularly near Benedict Canyon, act as a heat trap during Santa Ana wind events. Interior temperatures in those homes run significantly hotter than the flats a mile south, so attic and roof-deck insulation becomes performance-critical, not an afterthought. And in Trousdale Estates, nearly every flat-roof architect-designed home from the late 1950s and 1960s has the same failure pattern: original built-up roofing over fiberboard or no rigid insulation at all. When a reroofing crew strips the membrane, the problem is right there, and the replacement assembly has to satisfy both the Beverly Hills permit desk and the architectural profile that drives the home’s market value.
Our Main Beverly Hills Services
Two jobs dominate the calls we get from Beverly Hills homeowners: attic insulation in the big pre-war attics and crawl space encapsulation under homes built into hillside slopes. Here’s what each involves locally.
Attic Insulation in Beverly Hills
Most Beverly Hills attics in the 1920s-1940s Period Revival estates are open-framed and accessible, which makes them good candidates for air sealing plus blown-in or spray foam work. In Trousdale Estates, we’re often working against a flat roof deck instead of a vented attic, and that changes the entire approach. Permits here run through Beverly Hills’s own building department, and we coordinate that process so the architectural profile of the house stays intact while the R-value comes up to current Title 24 expectations. Full details live on our Attic Insulation in Beverly Hills page.
Crawl Space Encapsulation & Vapor Barrier in Beverly Hills
Hillside lots above Sunset often have partial or full crawl spaces cut into the slope, and those spaces pull moisture from the ground year-round. That moisture finds its way into floor joists, subflooring, and eventually the living space above. Sealing the crawl space with a vapor barrier and insulation changes the humidity profile of the whole house, which is especially noticeable in Beverly Hills where original hardwood floors react badly to seasonal moisture swings. See Crawl Space Encapsulation & Vapor Barrier in Beverly Hills for how we approach those jobs.

Spray Foam Insulation in Beverly Hills
Spray foam insulation in Beverly Hills is the most common request we get for the flat-roof mid-century homes in Trousdale Estates, where the original roof assembly has almost no thermal barrier. When a reroofing contractor pulls the old built-up membrane, homeowners finally see the fiberboard and empty cavities they’ve been heating and cooling for decades. Our Spray Foam Insulation installers are trained on open-cell and closed-cell applications in these exact conditions, including the heat-trap reality of the hills north of Sunset during Santa Ana events.
Open-Cell Spray Foam
Signs you need it
Rooms directly under the roof deck run 10 to 15 degrees hotter than the rest of the house in summer, even with the AC running.
What it costs in Beverly Hills
Expect $1.50 to $3.00 per board foot installed for open-cell foam in a Beverly Hills attic.
How we do it
We seal bypasses, mask off non-target surfaces, and spray the foam to full depth, letting it expand into every stud bay and rafter cavity.
Closed-Cell Spray Foam
Signs you need it
Your flat roof has no rigid insulation above the deck, and the ceilings below feel warm to the touch on hot afternoons.
What it costs in Beverly Hills
Closed-cell foam runs $2.50 to $4.50 per board foot installed, with the higher end common for hillside homes with difficult access.
How we do it
We spray the foam directly against the roof deck, creating an air, vapor, and thermal barrier in one pass that also stiffens the roof assembly.
What Spray Foam Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Open-cell spray foam (per board foot) | $1.50 - $3.00 |
| Closed-cell spray foam (per board foot) | $2.50 - $4.50 |
| Full attic spray foam job | $3,000 - $9,000 |
Is spray foam worth it on a flat-roof Trousdale home?
Yes. Closed-cell foam against the roof deck solves the missing-insulation problem without raising the roof profile, which matters when Beverly Hills’s permit desk reviews the assembly.
Can you spray foam around original lath-and-plaster walls?
Typically not, because the plaster has to come down first. During a gut renovation, once stud bays are open, foam goes in fast and air-seals the home in the same step.
Blown-In Insulation in Beverly Hills
Blown-in insulation in Beverly Hills handles the big open attics of the 1920s-1940s Period Revival estates south of Sunset. Those attics usually have old, settled insulation or none at all, with lath-and-plaster ceilings below. Our Blown-In Insulation crews bring hoses through tight second-story access points and fill even the oddest old framing without tearing anything apart.
Blown-In Cellulose
Signs you need it
The attic insulation you can see is thin, settled, or covered in dust from decades of Santa Ana wind intrusion.
What it costs in Beverly Hills
Blown-in cellulose runs $0.80 to $1.50 per square foot installed for typical Beverly Hills attics.
How we do it
We dense-pack or loose-fill the cellulose across the attic floor, covering every joist bay to a consistent depth.
Blown-In Fiberglass
Signs you need it
Your attic has shallow fiberglass batts that no longer meet Title 24 levels, and you want a quick, clean top-up.
What it costs in Beverly Hills
Blown-in fiberglass runs $0.70 to $1.40 per square foot installed, depending on final R-value.
How we do it
We blow fiberglass over the existing insulation after air sealing, building the depth up to the R-value your Beverly Hills project requires.
What Blown-In Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blown-in cellulose (per sq ft) | $0.80 - $1.50 |
| Blown-in fiberglass (per sq ft) | $0.70 - $1.40 |
| Whole-attic blown-in job | $1,500 - $3,500 |
Can you blow insulation over the old stuff in a 1930s attic?
After we check for wiring issues and air-seal the bypasses, yes. Most Beverly Hills attics from that era take a top-up cleanly without removing the old material.
How long does a blown-in job take in Beverly Hills?
A typical pre-war attic runs four to six hours for the insulation and air sealing. Call (213) 527-4062 and we’ll give you an exact window.
Radiant Barrier Installation in Beverly Hills
Radiant barrier installation in Beverly Hills targets the hillside homes north of Sunset that bake during Santa Ana heat events. A radiant barrier in the attic reflects radiant heat before it reaches the insulation below, which directly lowers ceiling temperatures in the flats just below the roof. Our Radiant Barrier Installation team staples foil to the underside of rafters in pre-war attics and adapts the approach for flat-roof homes where access is tighter.
Attic Radiant Barrier
Signs you need it
The upstairs rooms directly under the roof stay warm hours after sunset, even during mild evenings.
What it costs in Beverly Hills
Attic radiant barrier installs run $0.60 to $1.20 per square foot in Beverly Hills.
How we do it
We staple perforated radiant barrier foil to the underside of the roof rafters, leaving a reflective air gap facing the attic.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing a flat or low-slope Beverly Hills home and want to cut heat gain before the new membrane goes on.
What it costs in Beverly Hills
Roof deck radiant barrier adds $0.60 to $1.20 per square foot when combined with a reroof.
How we do it
We lay the radiant barrier over the deck before the roofer installs the new assembly, coordinating with the roofing crew’s schedule.
What Radiant Barrier Installation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic radiant barrier (per sq ft) | $0.60 - $1.20 |
| Roof deck radiant barrier (per sq ft) | $0.60 - $1.20 |
| Typical 2,000 sq ft attic install | $1,200 - $2,400 |
Does a radiant barrier help on a flat-roof mid-century home?
Yes, but it’s most effective when installed during a reroof, because the deck is exposed. Retrofitting from inside a Trousdale attic is harder without a ventilated air gap.
Will a radiant barrier reduce my AC bill in Beverly Hills?
Most homeowners see the biggest difference during heat waves, when radiant heat is strongest. The upstairs rooms stop absorbing as much heat from the roof.
Insulation Removal & Replacement in Beverly Hills
Insulation removal and replacement in Beverly Hills usually happens because of rodent damage, old vermiculite, or a renovation that’s opened the walls and revealed what’s really in there. Homes from the 1920s through the 1960s often have insulation that’s settled, contaminated, or simply never existed in the first place. Our Insulation Removal & Replacement crews pull the old material, sanitize the space, and install new insulation suited to the home’s era and architecture.
Attic Insulation Removal
Signs you need it
The attic insulation is loaded with dust, pest droppings, or has compressed to a fraction of its original depth.
What it costs in Beverly Hills
Attic insulation removal runs $1.00 to $2.50 per square foot in Beverly Hills.
How we do it
We vacuum the old insulation out with HEPA-filtered equipment, bag it, and prepare the attic for new material.
Vermiculite & Old Insulation Removal
Signs you need it
You have loose, pebble-like vermiculite in the attic, common in homes built before the 1960s, and you don’t know what’s in it.
What it costs in Beverly Hills
Vermiculite removal runs $5.00 to $15.00 per square foot because of testing and containment protocols.
How we do it
We follow EPA guidelines for containment and disposal, keeping the material sealed from living spaces throughout the job.
What Insulation Removal & Replacement Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic insulation removal (per sq ft) | $1.00 - $2.50 |
| Vermiculite removal (per sq ft) | $5.00 - $15.00 |
| Replacement blown-in install (per sq ft) | $0.70 - $1.50 |
Can you remove insulation without damaging original lath-and-plaster?
Yes. In attic floors, we work from above without disturbing the plaster ceiling below, and we take care not to overload the old framing with foot traffic.
How do I know if my old attic insulation has to come out?
If it’s vermiculite, pest-damaged, or full of decades of dust from canyon winds, removal is usually the right call. Call (213) 527-4062 for a straight answer.
Attic Air Sealing in Beverly Hills
Attic air sealing in Beverly Hills addresses the stack effect that pulls hot attic air down into living spaces and conditioned air up through the ceiling. In old lath-and-plaster homes, the bypasses are everywhere: around chimneys, interior walls, can lights, and plumbing chases. Our Attic Air Sealing techs find and seal those paths before any new insulation goes in, because new insulation over a leaky attic just creates a warmer leaky attic.
Attic Floor Air Sealing
Signs you need it
Dust streaks on insulation around interior wall tops show air is moving from the house into the attic.
What it costs in Beverly Hills
Attic floor air sealing runs $1.00 to $2.00 per square foot in Beverly Hills attractions.
How we do it
We clear insulation from each bay, foam or caulk the joints, and re-cover the sealed areas before blowing new insulation.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights in the ceiling feel warm, and you can feel air moving around the trim rings.
What it costs in Beverly Hills
Can light and duct boot sealing runs $50 to $150 per fixture, depending on access.
How we do it
We install rated covers over the fixtures or replace them with IC-rated units, then seal the drywall junction with foam or mastic.
What Attic Air Sealing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic floor air sealing (per sq ft) | $1.00 - $2.00 |
| Can light sealing (per fixture) | $50 - $150 |
| Whole-attic air sealing package | $800 - $2,000 |
Do I need air sealing if I’m adding insulation?
Yes, in almost every pre-war Beverly Hills home. Insulation slows heat transfer but does not stop air movement, and the air leaks are what make old homes feel drafty.
Will air sealing make my home too tight?
Not in a 1920s or 1950s house. These homes leak far more than modern standards, and sealing brings them closer to balanced ventilation, not past it.
Wall Insulation in Beverly Hills
Wall insulation in Beverly Hills is almost always a gut-renovation job, because the original lath-and-plaster walls have no cavity insulation to add to without opening them. When a homeowner is already down to studs for a remodel, that’s the moment to insulate. Our Wall Insulation installers work alongside general contractors or directly for homeowners during those remodels, keeping the schedule tight so the Beverly Hills permit window stays on track.
Injection Foam Wall Insulation
Signs you need it
Exterior walls are cold in winter and warm in summer, and you can feel the temperature difference by touching interior drywall.
What it costs in Beverly Hills
Injection foam wall insulation runs $2.00 to $4.00 per square foot of wall area.
How we do it
We drill small access holes through the plaster or drywall, inject the foam, and patch the holes to a smooth finish.
Drill & Fill Wall Insulation
Signs you need it
Your walls are original and uninsulated, and you want to improve comfort without a full gut renovation.
What it costs in Beverly Hills
Drill and fill runs $1.50 to $3.00 per square foot of wall area in Beverly Hills.
How we do it
We drill through the exterior or interior finish, blow cellulose or fiberglass into the bays, and restore the surface.
What Wall Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Injection foam wall insulation (per sq ft) | $2.00 - $4.00 |
| Drill & fill wall insulation (per sq ft) | $1.50 - $3.00 |
| Exterior wall insulation (per sq ft) | $3.00 - $6.00 |
Can you insulate original lath-and-plaster walls without removing them?
Yes, drill and fill works through the existing finish. We access the bays from inside or outside, fill them, and patch so the work disappears into the original surface.
Is insulating walls worth it before a Title 24 remodel?
Absolutely. Once walls are open, the incremental insulation cost is small compared to the remodel, and Title 24 compliance essentially requires it for permitted additions and major renovations.
Attic Cleaning & Rodent Proofing in Beverly Hills
Attic cleaning and rodent proofing in Beverly Hills matters because the canyon-adjacent neighborhoods north of Sunset put homes directly against natural rodent habitat. Rats and mice find their way into old attics through roofline gaps, and once inside they nest in the insulation. Our Attic Cleaning & Rodent Proofing crews remove the contaminated material, sanitize the space, and seal the entry points so the problem doesn’t restart.
Attic Cleanout
Signs you need it
You hear scratching at night, see droppings in the attic, or the insulation is matted and tunneled through.
What it costs in Beverly Hills
Attic cleanout runs $1.00 to $2.50 per square foot in Beverly Hills.
How we do it
We remove all contaminated insulation and debris with HEPA vacuums, bag everything, and haul it off the property.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents in the attic even after trapping, which means entry points are still open.
What it costs in Beverly Hills
Rodent proofing and exclusion runs $500 to $1,500 for the typical Beverly Hills roofline.
How we do it
We seal every gap along the roofline, vents, and utility penetrations with steel mesh, flashing, and foam, then verify the attic is clear.
What Attic Cleaning & Rodent Proofing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic cleanout (per sq ft) | $1.00 - $2.50 |
| Rodent proofing & exclusion | $500 - $1,500 |
| Full cleanout + reinsulation package | $2,500 - $6,000 |
Do you handle dead rodent removal from attics?
Yes, we remove carcasses during cleanouts and sanitize the affected insulation and framing before installing anything new.
How fast can you respond to a rat problem in Beverly Hills?
We schedule attic cleanouts quickly, often within a few days. Call (213) 527-4062 and a live person will get you on the calendar.
Home Energy Audit in Beverly Hills
A home energy audit in Beverly Hills pinpoints exactly where a 1920s estate or a 1960s Trousdale home is losing conditioned air, before you spend a dollar on insulation. The independent building department here means renovations often require documented performance testing, and an audit gives you that data. Our Home Energy Audit includes blower door testing, thermal imaging, and insulation inspection in one visit, with a written report you can hand to your contractor or the permit desk.
Blower Door Test
Signs you need it
Your home feels drafty, your energy bills are high, and you can’t identify where the leaks are coming from.
What it costs in Beverly Hills
A standalone blower door test runs $200 to $500 in Beverly Hills.
How we do it
We mount the blower door in an exterior frame and depressurize the house, measuring total air leakage in CFM.
Thermal Imaging Inspection
Signs you need it
Rooms are unevenly heated or cooled, and you suspect missing insulation in walls or ceilings.
What it costs in Beverly Hills
Thermal imaging adds $150 to $300 to a full energy audit.
How we do it
We scan walls, ceilings, and rim joists with an infrared camera while the blower door runs, mapping every weak spot.
What Home Energy Audit Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blower door test | $200 - $500 |
| Thermal imaging add-on | $150 - $300 |
| Full audit with report | $400 - $900 |
Will Beverly Hills building department accept your audit report?
In most cases, yes. The blower door and duct leakage numbers match what Title 24 compliance requires for permitted renovations, and we format the report accordingly.
How long does a home energy audit take?
Two to four hours for a typical Beverly Hills home. You’ll have the written report in hand by the time we leave.

What Beverly Hills Customers Say
"Crawl space was wet every spring. They laid the heavy liner, sealed the vents, and put a dehumidifier down there. Floors are warm and the moisture meter he left reads fine now. He still answers when I text him a reading."
- Devon Pierce"Spray foam in the garage ceiling under the bonus room. That room used to be unusable in summer. Walt talked me out of foaming the whole attic because it did not need it - saved me a couple thousand and I trust him more for it."
- Bud Larkin"The house had rats in the attic insulation and a smell we could not place. Walt's crew pulled all of it, sealed the gaps where they were getting in, sanitized, and put in new blown-in. He sent photos of the sealed openings so I could see it done."
