Insulation in Beverly Hills, CA
Crawl space encapsulation and vapor barrier work in Beverly Hills runs between $3,800 and $8,500 for most homes, with the pre-war estates in the flats often requiring full perimeter drainage and sump integration before sealing. We’re Envelope Insulation Co., and we’ve sealed and insulated over 9,000 homes since 2016 under The Haven Standard - every job starts with a written price and ends with a documented photo record. In Beverly Hills, we dispatch crews from our Los Angeles office and coordinate directly with the city’s own Building and Safety Division, not LADBS. Call (628) 226-1097 for a free estimate with upfront pricing.
Why Beverly Hills Homes Are Different
Beverly Hills operates its own Building and Safety Division, and inspectors here are accustomed to scrutinizing high-value custom remodels - plan submittals that sail through LA City counters often return for more detailed thermal envelope documentation. The flats south of Sunset hold 1920s-1940s Spanish Colonial, Tudor, and Georgian Revival estates built with essentially zero wall insulation and single-pane steel casement windows that leak conditioned air faster than any attic bypass. North of Sunset, Trousdale Estates packs flat-roof modernist homes from 1955-1964 where the entire thermal boundary lives in a shallow roof-ceiling cavity, making the insulation choice critical and the air sealing precision non-negotiable. Hillside elevations above the flats intensify radiant heat gain and reduce marine cooling, so attic temperatures run meaningfully higher even in this mild coastal-adjacent climate.
Our Main Beverly Hills Services
Most Beverly Hills homeowners who call us start with attic work or spray foam - here is where those jobs live on our site.
Attic Insulation in Beverly Hills
Attic insulation in Beverly Hills means different work depending on whether we’re above a 1930s estate with a vented attic or a 1960 Trousdale flat roof where the ceiling is the roof. In the older homes, we typically find original rock wool or nothing at all, with bypasses around chimneys and balloon-frame walls that must be sealed first. Attic Insulation in Beverly Hills covers the full scope, from loose-fill fiberglass over sealed attic floors to rigid board in conditioned attics.
Spray Foam Insulation in Beverly Hills
Spray foam is the upgrade path for Trousdale Estates homes where the roof-ceiling cavity is shallow and every inch of R-value matters. Open-cell foam at 3.5 inches depth yields roughly R-13 and allows roof deck drying; closed-cell at the same depth hits R-19 but requires careful moisture management in our mixed-dry climate. Spray Foam Insulation in Beverly Hills details material selection and blower-door verification.
Blown-In Insulation in Beverly Hills
Blown-in cellulose or fiberglass remains the most cost-effective retrofit for vented attics in the flat’s pre-war stock, but only after air sealing is complete - we regularly find 4,000+ CFM50 on blower-door tests in these homes before we start, and blowing insulation over an unsealed attic floor locks in the leaks permanently. Blown-In Insulation in Beverly Hills explains our sealed-first protocol.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Beverly Hills
Crawl space encapsulation in Beverly Hills addresses a specific problem: the 1920s-1940s estate homes in the flats were built over unvented or poorly vented crawl spaces with dirt floors and no vapor barrier, and our winter rains plus summer irrigation saturation drive ground moisture upward through rim joists and into finished floors. We provide Crawl Space Encapsulation & Vapor Barrier as a complete building-envelope service, and every encapsulation job includes a written scope, written warranty, and documented photo record before we leave.
Crawl Space Vapor Barrier
Signs you need it
Your hardwood floors cup seasonally, the crawl space dirt smells musty from the access hatch, or you find efflorescence on the foundation walls.
What it costs in Beverly Hills
Most vapor barrier installations in Beverly Hills run $3,800 to $5,200 for a standard estate crawl space under 2,000 square feet.
How we do it
We lay 6-mil minimum polyethylene over 100% of the dirt floor, seam-seal with waterproof tape, and extend the barrier 6 inches up foundation walls before sealing to the wall with polyurethane caulk.
Crawl Space Encapsulation
Signs you need it
You’re running dehumidifiers indoors year-round, finding mold on rim joists, or your HVAC ducts in the crawl space sweat condensation.
What it costs in Beverly Hills
Full encapsulation with closed-cell spray foam on walls, sealed vapor barrier, and mechanical dehumidification typically ranges $6,500 to $8,500 in Beverly Hills.
How we do it
We install closed-cell spray foam on foundation walls to R-10 minimum, seal the rim joist band completely, add a sealed vapor barrier floor, and install a dedicated dehumidifier with condensate pump to a daylight drain.
What Crawl Space Encapsulation & Vapor Barrier Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Vapor barrier (dirt floor, no walls) | $3,800 - $5,200 |
| Full encapsulation with foam walls | $6,500 - $8,500 |
| Dehumidifier with condensate pump | $1,200 - $2,400 |
How long does crawl space encapsulation take in Beverly Hills?
Most jobs finish in two to three days, with the first day dedicated to prep, cleaning, and any drainage correction. Call (628) 226-1097 to schedule a free estimate with written pricing.
Do I need a permit for crawl space work in Beverly Hills?
Yes - Beverly Hills Building and Safety issues its own permits, and we handle the submittal, thermal envelope documentation, and inspection scheduling as part of our scope. Call (628) 226-1097 and we’ll walk you through what your specific job requires.
Radiant Barrier Installation in Beverly Hills
Radiant barrier installation in Beverly Hills is driven by the hillside microclimate north of Sunset, where reduced marine cooling and intense solar exposure on dark flat roofs push attic temperatures well above ambient even in mild months. The 1955-1964 modernist homes of Trousdale Estates are particularly vulnerable - their shallow roof-ceiling cavities concentrate heat gain directly into conditioned space, and reflective barrier can reduce radiant heat transfer by 40% or more when properly installed. We provide Radiant Barrier Installation with before-and-after attic temperature documentation on every job.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms run 8-15 degrees hotter than downstairs by mid-afternoon, or your asphalt shingle roof is less than 10 years old and absorbs significant solar gain.
What it costs in Beverly Hills
Attic radiant barrier installation in Beverly Hills typically runs $2,400 to $4,200 for a 2,500-square-foot roof deck application.
How we do it
We staple perforated radiant barrier foil across the bottom of rafters with a minimum 3/4-inch air gap above, or lay it directly over existing attic insulation if the roof deck is inaccessible.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing a flat or low-slope roof and want integrated thermal performance without sacrificing interior ceiling height.
What it costs in Beverly Hills
Radiant barrier integrated with roof deck replacement in Beverly Hills ranges $4,800 to $7,500 depending on access and whether we’re working with modified bitumen or TPO.
How we do it
We install a radiant barrier substrate directly to the roof deck before membrane application, ensuring the reflective surface faces an air space and is protected from construction damage.
What Radiant Barrier Installation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic radiant barrier (foil, existing attic) | $2,400 - $4,200 |
| Radiant barrier roof deck (with reroof) | $4,800 - $7,500 |
| Radiant barrier with attic air sealing | $3,600 - $5,800 |
Does radiant barrier work in Beverly Hills’s mild climate?
Yes - hillside homes above Sunset see enough radiant gain that barrier pays back in 4-7 years, especially when combined with air sealing. Call (628) 226-1097 for a free estimate and written price.
Can radiant barrier be added to a flat roof?
Yes, but it must integrate with the roof assembly during reroofing or recovery - we install barrier substrate facing an air gap, then protect it during membrane application. Call (628) 226-1097 to discuss your specific roof.
Insulation Removal & Replacement in Beverly Hills
Insulation removal and replacement in Beverly Hills is common in the pre-war flats, where original rock wool, vermiculite, or uncompressed cellulose has settled, been compromised by rodent activity, or absorbed decades of dust and debris from unsealed attic bypasses. We never add new insulation over contaminated or compressed old material - it locks in the problem and voids most manufacturer warranties. We provide Insulation Removal & Replacement with full containment, HEPA filtration, and documented photo records of the cavity condition before new material goes in.
Contaminated Insulation Removal
Signs you need it
You’re finding rodent droppings in the attic, smelling urine when the HVAC runs, or seeing dark staining on the insulation surface.
What it costs in Beverly Hills
Contaminated insulation removal in Beverly Hills runs $2,800 to $4,500 for a typical estate attic, with decontamination and odor sealing adding $800 to $1,500.
How we do it
We establish negative air pressure with HEPA-scrubbed exhaust, remove all contaminated material in sealed bags, apply enzyme decontaminant to substrate, and verify with ATP swab testing before any new insulation is installed.
Insulation Replacement
Signs you need it
Your attic insulation measures less than R-19 depth, has visible compression or water staining, or was installed before 1980 and may contain vermiculite.
What it costs in Beverly Hills
Insulation replacement with new fiberglass or cellulose in Beverly Hills typically ranges $3,200 to $5,800 depending on attic square footage and access difficulty.
How we do it
We remove all existing material, seal every top plate, penetration, and bypass with foam and caulk, then install new blown-in fiberglass or cellulose to R-38 minimum per current Title 24 requirements.
What Insulation Removal & Replacement Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Contaminated insulation removal | $2,800 - $4,500 |
| Insulation replacement (new material only) | $3,200 - $5,800 |
| Removal + replacement + air sealing | $5,800 - $9,200 |
Is vermiculite insulation common in Beverly Hills homes?
Yes - estates built 1920-1950 often have vermiculite that may contain asbestos; we test first, and if positive, use licensed abatement partners. Call (628) 226-1097 for testing and a free written estimate.
How long does removal and replacement take?
Most jobs complete in two to four days: one day for removal and sealing, one for new insulation, with vermiculite abatement adding time. Call (628) 226-1097 for a schedule and written price.
Attic Air Sealing in Beverly Hills
Attic air sealing in Beverly Hills is the single most cost-effective envelope upgrade for the flats’ pre-war stock, where balloon-frame walls, unsealed top plates, and original can lights create a chimney effect that dumps conditioned air into the attic year-round. We regularly measure 4,000+ CFM50 on blower-door tests in these homes before sealing, and we won’t install any insulation until that number drops - it’s Haven Standard protocol. We provide Attic Air Sealing with before-and-after blower-door documentation on every applicable job.
Top Plate & Penetration Sealing
Signs you need it
Your upstairs walls are cold in winter despite good attic insulation, or you feel drafts at electrical outlets on exterior walls even with the HVAC off.
What it costs in Beverly Hills
Top plate and penetration sealing in Beverly Hills typically runs $1,800 to $3,200 for a 2,500-square-foot home with accessible attic.
How we do it
We foam-seal every top plate joint, wire penetration, plumbing vent, and chimney chase with fire-rated spray foam and high-temperature caulk, then verify with blower-door directed depressurization to locate remaining leaks.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed can lights flicker when it’s windy outside, or dust blows from ceiling registers when the system cycles on.
What it costs in Beverly Hills
Can light sealing with fire-rated covers and duct boot sealing in Beverly Hills ranges $1,200 to $2,400 depending on fixture count and duct configuration.
How we do it
We install pre-formed fire-rated enclosures over every non-IC can light, seal with fire-stop caulk, then mastic-seal all duct boots to the ceiling drywall and verify with pressure pan testing.
What Attic Air Sealing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Top plate & penetration sealing | $1,800 - $3,200 |
| Can light & duct boot sealing | $1,200 - $2,400 |
| Full attic air sealing (comprehensive) | $3,200 - $5,500 |
Will air sealing alone lower my energy bills in Beverly Hills?
Yes - in pre-war flats with 4,000+ CFM50, sealing alone typically reduces HVAC runtime 15-25% before any insulation is added. Call (628) 226-1097 for a blower-door test and written estimate.
Do you seal attic hatches in Beverly Hills homes?
Yes - we build insulated, weatherstripped hatch covers with latch compression that eliminate the single largest attic bypass in most homes. Call (628) 226-1097 to include this in your scope.
Wall Insulation in Beverly Hills
Wall insulation in Beverly Hills means retrofitting the 1920s-1940s estate homes in the flats, which were built with plaster-on-lath walls and essentially no cavity insulation - balloon-frame construction creates continuous channels from basement to attic that move air freely through wall cavities. Trousdale Estates homes from the 1950s-1960s typically have some batt insulation in walls but often suffer from settling, compression, or gaps at framing intersections. We provide Wall Insulation using injection foam, dense-pack cellulose, or drill-and-fill methods matched to each home’s construction type.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls are cold to the touch in winter, you hear street noise clearly through closed windows, or energy bills stay high despite attic upgrades.
What it costs in Beverly Hills
Injection foam wall insulation in Beverly Hills runs $4,500 to $7,200 for a typical 2,500-square-foot home with accessible stud cavities.
How we do it
We drill 5/8-inch holes through exterior stucco or interior plaster at stud-bay spacing, inject slow-rise polyurethane foam to fill the cavity completely, then patch and match finish.
Drill & Fill Wall Insulation
Signs you need it
You want cellulose or fiberglass in walls without full interior demolition, and your plaster is in good enough condition to patch.
What it costs in Beverly Hills
Dense-pack cellulose drill-and-fill in Beverly Hills typically ranges $3,800 to $6,200 depending on wall height, cavity depth, and access.
How we do it
We remove a strip of baseboard or crown, drill at top and bottom of each stud bay, dense-pack cellulose to 3.5 pounds per cubic foot with continuous hose agitation, then patch and repaint.
What Wall Insulation Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Injection foam (polyurethane) | $4,500 - $7,200 |
| Dense-pack cellulose drill-and-fill | $3,800 - $6,200 |
| Exterior rigid board (remodel/addition) | $6,500 - $10,500 |
Can you insulate walls without tearing out plaster in Beverly Hills?
Yes - injection foam and dense-pack cellulose both install through small holes that we patch and match; most original plaster stays intact. Call (628) 226-1097 for a free estimate and written scope.
Does wall insulation require a permit in Beverly Hills?
Yes - Beverly Hills Building and Safety requires permits for thermal envelope modifications, and we prepare the thermal documentation and schedule inspections. Call (628) 226-1097 and we’ll handle the paperwork.
Attic Cleaning & Rodent Proofing in Beverly Hills
Attic cleaning and rodent proofing in Beverly Hills addresses a specific problem in the pre-war estate stock: mature trees, established rooflines with multiple penetrations, and unsealed attic floors create entry highways for roof rats and squirrels that nest in insulation and compress it with trails and waste. We regularly find 6-12 inches of contaminated, compressed material in these attics, with active rodent traffic continuing through unsealed eave returns and chimney gaps. We provide Attic Cleaning & Rodent Proofing with full decontamination, exclusion sealing, and photo documentation of every entry point found and sealed.
Attic Sanitizing & Decontamination
Signs you need it
You’re hearing scratching at night, finding droppings in the attic, or smelling ammonia-like odor through ceiling registers when the HVAC runs.
What it costs in Beverly Hills
Attic sanitizing and decontamination in Beverly Hills runs $2,400 to $4,200 for a typical estate attic with moderate contamination.
How we do it
We remove all contaminated insulation under HEPA containment, apply enzyme-based decontaminant to all surfaces, fog with odor neutralizer, and verify with ATP testing before any new material is installed.
Rodent Proofing & Exclusion
Signs you need it
You’re trapping rodents repeatedly, finding new droppings after cleanup, or seeing gnaw marks on fascia boards and eave returns.
What it costs in Beverly Hills
Rodent proofing and exclusion in Beverly Hills typically ranges $1,800 to $3,600 depending on roof complexity, entry point count, and whether we’re working with tile, shingle, or flat roof assemblies.
How we do it
We inspect every roof penetration, eave return, vent, and chimney gap with photo documentation, seal all entry points with rodent-proof mesh and sealant, and provide a written exclusion report with photos of every location addressed.
What Attic Cleaning & Rodent Proofing Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Attic sanitizing & decontamination | $2,400 - $4,200 |
| Rodent proofing & exclusion | $1,800 - $3,600 |
| Full attic restoration (clean + seal + reinsulate) | $6,500 - $11,500 |
How do I know if rodents are in my Beverly Hills attic?
Listen for scratching at dawn or dusk, check for droppings near attic hatches, and look for compressed insulation trails - roof rats leave 1/2-inch droppings and greasy rub marks. Call (628) 226-1097 for inspection and written pricing.
Does rodent proofing include trapping?
We seal every entry point to prevent return; active infestations require a licensed pest control partner for trapping, then we handle the cleanup, decontamination, and reinsulation. Call (628) 226-1097 to coordinate the full scope.
Home Energy Audit in Beverly Hills
A home energy audit in Beverly Hills gives owners of pre-war estates and mid-century moderns the documentation they need to prioritize envelope upgrades against a backdrop of high construction costs and strict permit requirements. Our audit protocol - blower-door testing, thermal imaging, and duct leakage measurement - produces the exact CFM50 number, the infrared images of thermal bypasses, and the written scope that Beverly Hills Building and Safety expects for permit submittals on thermal envelope work. We provide Home Energy Audit with all documentation delivered within 48 hours, including prioritized recommendations with written price ranges for each measure.
Blower Door Test
Signs you need it
Your energy bills are high despite recent HVAC replacement, rooms have uneven temperatures, or you’re planning envelope work and need a baseline for verification.
What it costs in Beverly Hills
A standalone blower-door test in Beverly Hills runs $450 to $650, or it’s included at no additional charge when bundled with a full energy audit.
How we do it
We install a calibrated blower door in an exterior doorway, depressurize the house to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure - to establish your exact envelope tightness.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls, want to locate hidden air leaks before drywall repair, or need infrared documentation for a permit or insurance claim.
What it costs in Beverly Hills
Thermal imaging inspection in Beverly Hills typically ranges $350 to $550 as a standalone service, or it’s bundled with our full audit.
How we do it
We scan every interior and exterior surface with a FLIR thermal camera during blower-door depressurization to make air leaks visible as temperature differentials, then annotate images with location and severity ratings.
What Home Energy Audit Costs in Beverly Hills
| Item | Typical range in Beverly Hills |
|---|---|
| Blower-door test (standalone) | $450 - $650 |
| Thermal imaging inspection | $350 - $550 |
| Full home energy audit (comprehensive) | $850 - $1,400 |
Is a blower-door test required for permit work in Beverly Hills?

What Beverly Hills Customers Say
"They air-sealed the attic floor before insulating and showed me the blower-door number before and after. The upstairs is finally the same temperature as downstairs."
- Marisol D."They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R.
