Insulation in Beverly Hills, CA
Spray foam insulation in Beverly Hills usually costs $2.40-$7.50 per board foot, with closed-cell jobs on Trousdale-era flat-roof homes landing at the top of that range. Most Beverly Hills homes were built between the 1920s and 1960s with hollow plaster walls or minimal original insulation, so we spend a lot of time retrofitting spaces that were never designed for modern comfort. Call (424) 622-5846 and a live person answers 24/7, not a voicemail tree.
Why Beverly Hills Homes Are Different
The flats south of Santa Monica Boulevard hold large Spanish Colonial Revival, Tudor, and Mediterranean Revival estates from the 1920s through 1940s. Most still have their original plaster-on-lath walls with zero cavity insulation, which means drilling through stucco or ornamental plaster is a high-stakes decision on a multimillion-dollar home. North of Sunset, including Trousdale Estates, post-and-beam flat-roof modernists from the late 1950s and early 1960s were designed for indoor-outdoor living with minimal envelope insulation, and their flat roof decks absorb direct afternoon sun in a way pitched roofs never do.
Beverly Hills operates its own municipal building department, separate from LA City and LA County. Every permit, Title 24 compliance pathway, and inspection runs through a small, exacting local office. Trousdale renovation projects routinely require closed-cell spray foam on the underside of existing flat-roof decks to avoid disrupting the architectural roofline, but the design-review process means even mechanical penetrations for blown-in insulation on street-facing walls must be documented and approved. Contractors who do most of their work across the city line get caught off guard by how closely Beverly Hills scrutinizes high-value properties.
Our Main Beverly Hills Services
Most Beverly Hills homeowners call us first about the two spaces that leak the most conditioned air: the attic above and the crawl space below. Here’s what each job involves locally.
Attic Insulation in Beverly Hills
Older flat homes in the flats often still have original 1930s-era batt remnants or nothing at all, while Trousdale-era flat-roof homes need spray foam applied to the underside of the roof deck rather than the attic floor. We map the existing insulation, seal bypasses, then bring the assembly up to current Title 24 levels without disturbing original plaster details. Read more on our dedicated Attic Insulation in Beverly Hills page.
Crawl Space Encapsulation & Vapor Barrier in Beverly Hills
Many 1920s-1940s estates have vented crawl spaces that pull damp, musty air into the living space all year. We seal the floor and foundation walls with a reinforced vapor barrier, address drainage at the perimeter, and turn the crawl space into a dry, conditioned zone. Read more on our dedicated Crawl Space Encapsulation & Vapor Barrier in Beverly Hills page.

Spray Foam Insulation in Beverly Hills
Spray foam is the workhorse for Beverly Hills flat-roof modernists and hillside homes north of Sunset, where afternoon heat and Santa Ana winds superheat roof decks and make comfort a real fight. Closed-cell foam applied to the underside of a Trousdale roof deck adds insulation, air sealing, and structural rigidity in one pass without changing the roofline the design-review board approved. We run more closed-cell roof-deck jobs here than almost anywhere else in the LA area, and our crews know the permit office’s expectations before we start. For a broader look at options, see our Spray Foam Insulation hub.
Closed-Cell Spray Foam
Signs you need it
Rooms under a flat roof deck are 8-12 degrees hotter than the rest of the house on summer afternoons, and energy bills spike during Santa Ana events.
What it costs in Beverly Hills
Closed-cell spray foam typically runs $3.50-$7.50 per board foot in Beverly Hills depending on depth and access.
How we do it
We prep the roof-deck underside, spray the foam to the specified depth in continuous lifts, then trim and inspect the final surface for full adhesion.
Garage Ceiling Spray Foam
Signs you need it
The room above the garage never holds temperature, and the garage door opening blasts heat or cold into the ceiling assembly all day.
What it costs in Beverly Hills
Garage ceiling spray foam usually runs $2.40-$4.50 per board foot depending on whether you choose open-cell or closed-cell.
How we do it
We mask and ventilate the garage, spray the ceiling cavity to the target R-value, and trim back to the joist lines for a clean finish.
What Spray Foam Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Open-cell spray foam | $2.40-$3.80 per board foot |
| Closed-cell spray foam | $3.50-$7.50 per board foot |
| Spray foam roof deck retrofit | $4.50-$7.50+ per board foot |
Can spray foam be applied to a 1960s flat roof deck without re-roofing?
Yes. Closed-cell foam goes directly onto the underside of the existing deck between the joists, so the roofline and exterior finish stay untouched. Call (424) 622-5846 for an exact quote.
Will spray foam trigger a Beverly Hills permit review?
Most spray foam jobs on flat-roof or street-facing assemblies do require documentation through Beverly Hills’s building department. We prepare the submittal and handle the inspection path so you don’t have to.
Blown-In Insulation in Beverly Hills
Blown-in insulation is the cleanest retrofit for the 1920s-1940s estate homes in the flats, where original plaster walls and ornate ceilings rule out tearing into cavities. We blow loose-fill fiberglass or cellulose into attic floors and, with dense-pack techniques, into closed wall cavities through small, strategically placed access holes. For more detail, see our Blown-In Insulation hub.
Dense-Pack Wall Insulation
Signs you need it
Rooms along exterior walls feel cold in winter and hot in summer, and the walls sound hollow when you knock on them.
What it costs in Beverly Hills
Dense-pack wall insulation typically runs $2.20-$4.00 per square foot of wall area in Beverly Hills.
How we do it
We drill small access holes through stucco or plaster, dense-pack cellulose or fiberglass into each cavity at pressure, then patch and touch up discreetly.
Blown-In Top-Up
Signs you need it
The attic has old batts or loose fill settled below the joist tops, and upstairs rooms run hot despite the AC running constantly.
What it costs in Beverly Hills
Blown-in top-up over existing insulation runs $1.25-$2.50 per square foot depending on final R-value.
How we do it
We air-seal the attic floor, then blow fresh loose fill over the existing material to reach the target depth and R-value.
What Blown-In Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blown-in attic floor (new) | $1.75-$3.25 per square foot |
| Dense-pack wall insulation | $2.20-$4.00 per square foot |
| Blown-in top-up | $1.25-$2.50 per square foot |
Will blown-in insulation damage my original plaster walls?
No, the access holes are small and patched to match, and we never open full wall cavities. The plaster face stays intact.
Can you dense-pack walls in a Spanish Colonial Revival home?
Yes, we dense-pack through the exterior stucco or interior plaster, whichever offers cleaner access and better patch matching on your home.
Radiant Barrier Installation in Beverly Hills
Radiant barrier pays off most on hillside homes north of Sunset, where summer afternoons run noticeably hotter than the flats and roof decks bake under direct sun. A foil radiant barrier under the roof deck reflects radiant heat away before it can soak into the attic and push down into living spaces. See our Radiant Barrier Installation hub for the full picture.
Attic Radiant Barrier
Signs you need it
The attic hits 130 degrees or more on summer afternoons even with vents open, and the AC cycles constantly in the late afternoon.
What it costs in Beverly Hills
Attic radiant barrier runs $0.60-$1.50 per square foot of attic floor area in Beverly Hills.
How we do it
We staple a reinforced foil barrier to the underside of the rafters, keeping the reflective side facing the roof deck’s air gap.
Radiant Barrier & Ventilation
Signs you need it
The attic stays hot and stuffy even at night, and you can feel heat radiating from the ceiling after sundown.
What it costs in Beverly Hills
Radiant barrier paired with ventilation upgrades runs $1.40-$2.80 per square foot depending on the venting work required.
How we do it
We install the foil barrier, then verify and upgrade intake and exhaust ventilation so the reflective surface can actually do its job.
What Radiant Barrier Installation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic radiant barrier | $0.60-$1.50 per square foot |
| Radiant barrier foil | $0.40-$1.00 per square foot |
| Radiant barrier & ventilation | $1.40-$2.80 per square foot |
Is radiant barrier worth it in a mild climate like Beverly Hills?
Yes, especially on hillside and flat-roof homes that catch direct afternoon sun. Reflecting radiant heat away before it enters the attic cuts AC runtime measurably.
Can radiant barrier be added to an existing attic without removing insulation?
Yes. We install it against the rafters, so the existing attic floor insulation stays in place and keeps doing its job.
Insulation Removal & Replacement in Beverly Hills
Many 1920s-1940s Beverly Hills attics still hold their original 1930s-era batt remnants, or loose fill that’s been contaminated by decades of rodent activity in the hillside neighborhoods. When insulation is damp, compacted, or full of droppings, removal is the only honest starting point. For the full breakdown, see our Insulation Removal & Replacement hub.
Attic Insulation Removal
Signs you need it
Old insulation is matted, settled below the joists, or visibly dirty, and upstairs rooms never hold temperature.
What it costs in Beverly Hills
Attic insulation removal runs $1.00-$2.50 per square foot depending on depth and access in Beverly Hills.
How we do it
We vacuum out the old material with HEPA-filtered equipment, bag it, and leave the attic floor clean and ready for new insulation.
Contaminated Insulation Removal
Signs you need it
You smell musty or ammonia-like odors from the attic, or you’ve seen rodent droppings or nesting material in the insulation.
What it costs in Beverly Hills
Contaminated insulation removal typically runs $1.50-$3.00 per square foot including sanitizing.
How we do it
We remove the contaminated material, sanitize the deck and framing, seal entry points, and install fresh insulation in the same visit.
What Insulation Removal & Replacement Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic insulation removal | $1.00-$2.50 per square foot |
| Contaminated insulation removal | $1.50-$3.00 per square foot |
| Insulation replacement | $2.00-$3.50 per square foot |
How do I know if my Beverly Hills attic insulation needs replacing?
If the material is matted, damp, or full of rodent waste, it’s no longer performing and should come out. Call (424) 622-5846 and we’ll inspect it honestly.
Can you remove and replace insulation in one visit?
Yes, most removal and replacement jobs are completed in a single visit, so your home isn’t left open and unprotected between trips.
Attic Air Sealing in Beverly Hills
Attic air sealing is the quiet fix behind a lot of Beverly Hills comfort complaints, especially in older estate homes where original framing left gaps around chimneys, can lights, and top plates. Sealing those bypasses stops conditioned air from escaping into the attic and keeps hot attic air from pushing down into bedrooms. For the full method, see our Attic Air Sealing hub.
Attic Floor Air Sealing
Signs you need it
Upstairs rooms are drafty in winter and stuffy in summer even after adding insulation, and dust keeps collecting on surfaces.
What it costs in Beverly Hills
Attic floor air sealing runs $0.80-$1.80 per square foot depending on how many penetrations need sealing.
How we do it
We pull back existing insulation, seal every gap, crack, and penetration in the attic floor with foam and caulk, then reinstall the insulation.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights feel warm to the touch or you can feel air moving around them, and duct registers don’t blow as hard as they should.
What it costs in Beverly Hills
Can light and duct boot sealing runs $15-$35 per fixture or boot in Beverly Hills.
How we do it
We seal around each can light housing and duct boot with rated materials, restoring the air barrier without blocking the fixtures.
What Attic Air Sealing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic floor air sealing | $0.80-$1.80 per square foot |
| Top plate & penetration sealing | $1.00-$2.00 per linear foot |
| Can light & duct boot sealing | $15-$35 per fixture or boot |
How much of my energy bill is attic air leaks in Beverly Hills?
In older estate homes with original framing, attic bypasses commonly account for 20-30% of total air leakage. Sealing them is the highest-value comfort fix per dollar.
Will air sealing make my house too tight?
No, we seal bypasses between the house and attic, which is what building science calls for. We’re not sealing your home against ventilation it actually needs.
Wall Insulation in Beverly Hills
Wall insulation in the flats means working around hollow plaster-on-lath cavities in 1920s-1940s estate homes, where drilling through ornamental plaster or stucco is a decision you make once. In Trousdale-era homes, it means insulating post-and-beam walls that were designed with almost no envelope consideration at all. For a deeper look, see our Wall Insulation hub.
Drill & Fill Wall Insulation
Signs you need it
Exterior walls feel cold to the touch in winter, and rooms facing the street or hillside never hold temperature.
What it costs in Beverly Hills
Drill and fill wall insulation runs $2.20-$3.80 per square foot of wall area in Beverly Hills.
How we do it
We drill small access holes, blow loose fill into each cavity to full density, then patch and color-match the surface so it disappears.
Interior Wall Soundproofing
Signs you need it
You hear street noise, neighbor conversations, or plumbing runs through bedroom and living room walls.
What it costs in Beverly Hills
Interior wall soundproofing runs $2.80-$5.00 per square foot depending on the assembly and materials.
How we do it
We dense-pack interior cavities with sound-damping insulation, often Rockwool, which also adds fire resistance and thermal mass.
What Wall Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Drill & fill wall insulation | $2.20-$3.80 per square foot |
| Injection foam wall insulation | $2.80-$5.00 per square foot |
| Interior wall soundproofing | $2.80-$5.00 per square foot |
Will drilling into my original plaster crack it?
We use low-torque drilling and patching techniques designed for old plaster. Cracking is rare when done correctly, and we photograph every penetration before patching.
Can you insulate walls without touching the exterior facade?
Yes, we often work from the interior side in Beverly Hills to preserve original stucco or architectural details, then patch and color-match the interior surface.
Attic Cleaning & Rodent Proofing in Beverly Hills
Beverly Hills hillside neighborhoods sit right against open canyon land, and rodents find their way into older attics through original roof eaves and vent openings. We clean out contaminated insulation, sanitize the space, and seal every entry point so they can’t come back. For the complete process, see our Attic Cleaning & Rodent Proofing hub.
Attic Cleanout
Signs you need it
The attic has visible rodent droppings, nesting material, or old debris, and you hear scratching sounds in the evening.
What it costs in Beverly Hills
Attic cleanout runs $1.50-$3.00 per square foot depending on depth and contamination level in Beverly Hills.
How we do it
We vacuum out everything with HEPA equipment, bag and dispose of the waste, and leave the space ready for new insulation.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents in the attic before, or you notice gaps around roof eaves, vents, and pipe penetrations.
What it costs in Beverly Hills
Rodent proofing and exclusion runs $400-$1,200 depending on the number of entry points and linear feet of sealing.
How we do it
We seal every entry point with steel mesh, foam, and flashing, then verify the attic is fully excluded before we finish.
What Attic Cleaning & Rodent Proofing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic cleanout | $1.50-$3.00 per square foot |
| Attic sanitizing & decontamination | $500-$1,200 |
| Rodent proofing & exclusion | $400-$1,200 |
Will attic cleaning get rid of the smell?
Yes, we remove the contaminated insulation and sanitize the decking and framing, which eliminates the source of the odor rather than masking it.
Can you rodent-proof my attic in the same visit as the cleanout?
Yes, most cleanout and exclusion jobs are completed in a single visit, so the attic is left clean, dry, and sealed before we leave.
Home Energy Audit in Beverly Hills
A home energy audit is the diagnostic starting point that makes every other insulation job smarter, especially in Beverly Hills where homes range from 1920s plaster estates to 1960s post-and-beam moderns with completely different failure modes. The blower door and thermal imaging show us exactly where your home leaks air and heat, so we fix what matters first. For the full scope, see our Home Energy Audit hub.
Blower Door Test
Signs you need it
Rooms never hold temperature and energy bills are high, but you don’t know where the air is actually leaking.
What it costs in Beverly Hills
A blower door test runs $250-$450 as part of a full audit in Beverly Hills.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure total air leakage in CFM at 50 pascals.
Thermal Imaging Inspection
Signs you need it
Certain walls or ceilings feel cold or hot in patches, and you want to see the actual heat loss without opening anything up.
What it costs in Beverly Hills
Thermal imaging inspection runs $150-$300 as an add-on or part of a full audit.
How we do it
We scan every wall, ceiling, and floor with an infrared camera while the blower door is running, then document every anomaly with photos.
What Home Energy Audit Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Full home energy audit | $450-$800 |
| Blower door test | $250-$450 |
| Thermal imaging inspection | $150-$300 |
Is a home energy audit worth it before a big insulation job?
Yes, the audit shows exactly where leaks and weak spots are, so you don’t spend money insulating the wrong part of the house. Call (424) 622-5846 to schedule one.
Can you do the audit and the insulation work in the same week?
Yes, we schedule the audit first, then return with the crew to fix what the audit found. Most Beverly Hills jobs move from audit to finished work within days.

What Beverly Hills Customers Say
"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
- Priya Raman"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."
