Insulation in Inglewood, CA
Crawl space encapsulation and vapor barrier installation in Inglewood typically runs $2,800-$6,500 depending on crawl space size and existing moisture damage, with most jobs completed in one to two days. The combination of Inglewood’s marine-layer humidity and post-war crawl space construction - most homes built 1940s through 1960s with minimal ground sealing - makes this the starting point for envelope work here. Call (424) 704-9866 for a written price before any work starts.
We’re Envelope Insulation Co., operating under The Haven Standard since 2016. Our crews serve Inglewood from the brand’s Los Angeles office, and every job begins with a written scope and flat price - no exceptions. On applicable jobs, we publish before-and-after blower-door numbers so you can verify the air-sealing result in a single figure.
Why Inglewood Homes Are Different
Inglewood sits directly beneath LAX’s primary flight paths, placing large areas within 65+ dB Day-Night Level noise contours. LA World Airports’ Residential Sound Insulation Program has retrofitted thousands of homes with acoustic windows and doors, but typically leaves attic and wall cavities untouched - meaning insulation contractors here work at the intersection of noise-dampening and thermal performance, a combination rarely as pressing in neighboring Hawthorne or Culver City.
The housing stock is dominated by post-WWII stucco-over-wood-frame bungalows and tract homes built from the late 1930s through the 1960s, most constructed with minimal or zero wall cavity insulation. The persistent marine layer, especially during May-July “June Gloom,” drives attic moisture accumulation that degrades fiberglass batts and can promote mold in poorly ventilated roof assemblies. This mild climate led builders to systematically underinsulate, making retrofits cost-effective even though peak thermal loads are moderate. Homes near the airport that received LAWA sound insulation often have brand-new acoustic window inserts paired with original 1950s-era compressed fiberglass or no attic insulation at all.
Our Main Inglewood Services
Inglewood homeowners most often call us about attic work and spray foam - here is what those jobs involve locally.
Attic Insulation in Inglewood
Attic insulation in Inglewood means addressing decades of compressed or absent fiberglass in roof assemblies that were never designed for thermal performance. The marine layer keeps attics cooler than inland valleys but wetter, so we inspect for moisture degradation before recommending material. Most attic jobs here follow air sealing, not replace it. Attic Insulation in Inglewood
Spray Foam Insulation in Inglewood
Spray foam insulation in Inglewood works well for the tight cavities and irregular framing common in post-war tract construction. Closed-cell foam adds structural rigidity and vapor resistance, which matters in attics where June Gloom moisture accumulates. We specify Demilec or Icynene products, with no proprietary lock-in. Spray Foam Insulation in Inglewood
Blown-In Insulation in Inglewood
Blown-in insulation in Inglewood is often the most practical retrofit for homes with intact but underinsulated attics. We use Owens Corning or Johns Manville loose-fill, installed after top plates and penetrations are sealed - never over unsealed air leaks. The material fills irregular joist bays better than batts in these older framed roofs. Blown-In Insulation in Inglewood

Crawl Space Encapsulation & Vapor Barrier in Inglewood
Inglewood’s post-war crawl spaces were built with dirt floors and minimal ventilation, and the marine layer keeps ground moisture persistent year-round. Encapsulation stops that moisture from migrating into floor assemblies and degrading indoor air quality. Crawl Space Encapsulation & Vapor Barrier is the foundation of envelope work in this climate - we won’t insulate above a damp crawl space.
Crawl Space Vapor Barrier
Signs you need it
Musty odors rising from floor registers, visible condensation on ductwork in the crawl space, or sagging fiberglass batts hanging below joists indicate ground moisture is unchecked.
What it costs in Inglewood
A 6-mil to 20-mil vapor barrier installed over bare dirt in an Inglewood crawl space typically runs $1,200-$2,800 for homes under 1,500 square feet.
How we do it
We remove debris, grade the dirt floor, seam-seal polyethylene sheeting at all overlaps, and mechanically fasten to foundation walls - then deliver a Documented Photo Record of the sealed ground plane.
Crawl Space Encapsulation
Signs you need it
Standing water after rain, mold on floor joists, or hardwood cupping above the crawl space means vapor barrier alone won’t solve the problem.
What it costs in Inglewood
Full encapsulation with sealed vapor barrier, wall insulation, and conditioned air supply in Inglewood generally ranges $4,500-$8,500 depending on perimeter wall height and access constraints.
How we do it
We install sealed vapor barrier on floors and walls, close vents, add mechanical dehumidification if needed, and air-seal rim joists before any insulation goes in - sealed first, then insulated, always.
What Crawl Space Encapsulation & Vapor Barrier Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Vapor barrier (6-20 mil, dirt floor) | $1,200-$2,800 |
| Partial encapsulation (barrier + wall sealing) | $3,200-$5,500 |
| Full encapsulation with dehumidification | $4,500-$8,500 |
How long does crawl space encapsulation take in Inglewood?
Most vapor barrier jobs finish in one day; full encapsulation with dehumidification typically takes two to three days. We coordinate scheduling from our Los Angeles office and text when the crew is en route.
Will encapsulation help with the musty smell in my Inglewood home?
Yes - sealing the ground plane and controlling humidity at the source eliminates the conditions that produce musty odors. Call (424) 704-9866 for a free inspection and written price.
Radiant Barrier Installation in Inglewood
Inglewood’s mild summers mean attic temperatures rarely reach the extremes of inland valleys, but the combination of uninsulated post-war roof decks and LAX noise-mitigation programs that ignore attics leaves many homes with hot, radiant-gain-prone ceilings. Radiant barrier reflects infrared heat rather than absorbing it, lowering cooling loads in homes where the attic was never addressed. Radiant Barrier Installation pairs well with air sealing in these older framed roofs.
Attic Radiant Barrier
Signs you need it
Upstairs rooms that stay hot after sunset, high summer cooling bills despite moderate outdoor temperatures, or an attic floor too hot to touch indicate radiant heat gain through the roof deck.
What it costs in Inglewood
Attic radiant barrier installation in Inglewood typically runs $1,500-$3,200 for a single-story home, depending on attic square footage and accessibility.
How we do it
We staple perforated foil across rafter bays or lay it over existing attic insulation, maintaining ventilation channels - always after air sealing is complete, never before.
Radiant Barrier & Ventilation
Signs you need it
Attic mold, rusted nail heads on the roof deck, or insulation that feels damp to the touch mean radiant barrier alone will trap moisture without improved airflow.
What it costs in Inglewood
Radiant barrier with added soffit and ridge ventilation in Inglewood generally costs $2,800-$5,500, including baffle installation to preserve intake pathways.
How we do it
We install baffles at soffits, verify ridge vent clearance, then apply radiant barrier - documenting before-and-after attic temperature readings when applicable.
What Radiant Barrier Installation Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Attic radiant barrier (foil, staple-up) | $1,500-$3,200 |
| Radiant barrier with ventilation upgrade | $2,800-$5,500 |
| Radiant barrier roof deck (new construction or reroof) | $3,500-$6,800 |
Does radiant barrier work in Inglewood’s mild climate?
Yes - it reduces cooling loads even when peak temperatures are moderate, and the payoff is faster in homes with zero existing attic insulation. Call (424) 704-9866 for a written estimate.
Can radiant barrier go over my old insulation?
We prefer to lay it over existing insulation only after air sealing and inspection for moisture damage; in damp attics, we address ventilation first.
Insulation Removal & Replacement in Inglewood
Inglewood’s post-war homes often contain original fiberglass batts compressed to half their labeled R-value, or in some cases vermiculite that may contain asbestos. The LAWA sound insulation program touched windows and doors but left attics alone, so many homes have 70-year-old insulation under relatively new acoustic retrofits. Insulation Removal & Replacement starts with testing and documentation, not demolition.
Attic Insulation Removal
Signs you need it
Insulation flattened to less than half its original thickness, visible water staining, or rodent droppings throughout the attic mean removal precedes any new material.
What it costs in Inglewood
Attic insulation removal in Inglewood typically runs $1,800-$3,500 for a 1,200-1,800 square foot home, depending on access and contamination level.
How we do it
We contain the attic space, remove material with HEPA-filtered equipment, bag on-site, and deliver a Documented Photo Record of the clean deck before any replacement begins.
Contaminated Insulation Removal
Signs you need it
Strong ammonia odor from rodent urine, visible mold on insulation facing, or pest activity in the attic indicates contaminated material that should not be disturbed without protection.
What it costs in Inglewood
Contaminated insulation removal with sanitizing in Inglewood generally ranges $3,200-$6,500, including PPE, HEPA containment, and disposal.
How we do it
We suit in full PPE, establish negative air pressure, remove and bag contaminated material, apply enzymatic sanitizer to affected structures, and verify clearance before reinsulating.
What Insulation Removal & Replacement Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Standard attic insulation removal | $1,800-$3,500 |
| Contaminated insulation removal + sanitizing | $3,200-$6,500 |
| Removal + replacement with new batts or blown-in | $4,500-$9,000 |
How do I know if my Inglewood home has asbestos in the insulation?
Vermiculite insulation, common in homes built 1940-1980, requires lab testing before disturbance - we collect samples and wait for results before scheduling removal. Call (424) 704-9866 to arrange testing.
Can you remove insulation without replacing it the same day?
Yes - we often separate removal and replacement to allow for repairs, air sealing, or drying; the written scope specifies the schedule before work starts.
Attic Air Sealing in Inglewood
Inglewood’s post-war tract homes were built with top plates, can lights, and duct boots left open to the attic - standard practice in an era when energy was cheap and air conditioning rare. The marine layer means these leaks pull humid outdoor air into the attic year-round, accelerating insulation degradation and mold risk. Attic Air Sealing is the hard prerequisite we never skip; we publish blower-door numbers on every job so you can see the exact reduction in conditioned air loss.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling fixtures, cold drafts in exterior wall corners during winter, or insulation that appears to have been blown around by air movement indicate leaky top plates.
What it costs in Inglewood
Top plate and penetration sealing in Inglewood typically runs $1,200-$2,800 for a single-story home, depending on wall length and number of wire/plumbing penetrations.
How we do it
We access top plates from the attic, seal with fire-rated caulk and rigid foam, photograph each sealed penetration, and run a blower-door test before and after to document the reduction.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that flicker in windy weather, visible gaps around ductwork where it enters the ceiling, or rooms that never reach set temperature despite adequate insulation point to leaky boots and fixtures.
What it costs in Inglewood
Can light and duct boot sealing in Inglewood generally costs $800-$2,200, including fire-rated covers for non-IC-rated fixtures and mastic-sealed duct connections.
How we do it
We install pre-formed fire covers over can lights, seal duct boots with mastic and mesh, and verify with blower-door - the Haven Standard requires written numbers, not feelings.
What Attic Air Sealing Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Top plate and penetration sealing | $1,200-$2,800 |
| Can light and duct boot sealing | $800-$2,200 |
| Full attic air sealing (comprehensive) | $2,500-$5,000 |
What is a blower-door test and why does it matter for my Inglewood home?
A blower-door test is a pressurization reading that shows, in one number, how much air your building envelope is losing - we provide before-and-after readings on every air-sealing job so you can verify the result. Call (424) 704-9866 to schedule.
Can air sealing help with the noise from LAX flights?
Air sealing reduces the paths sound travels through, but for significant noise reduction we assess whether wall and attic insulation upgrades should follow - we write that scope before any work starts.
Wall Insulation in Inglewood
Inglewood’s post-war stucco homes were built with empty wall cavities - no insulation, no air barrier, just stucco over wire lath and open framing. The LAWA sound program added windows but left walls hollow, so many homes still transmit both thermal energy and aircraft noise through the same uninsulated planes. Wall Insulation in these homes requires drilling access and material selection that won’t trap moisture against stucco.
Drill & Fill Wall Insulation
Signs you need it
Exterior walls that are cold to the touch in winter, hot in summer, or rooms adjacent to flight paths that remain loud despite new windows indicate empty cavities.
What it costs in Inglewood
Drill-and-fill wall insulation with dense-pack fiberglass or cellulose in Inglewood typically runs $2,500-$5,500 for a 1,200-square-foot home, including stucco patch and match.
How we do it
We drill 2-inch holes at stud bays, dense-pack Knauf or GreenFiber to 3.5 pounds per cubic foot, patch with matching stucco texture, and photograph the filled cavity with an endoscope.
Interior Wall Soundproofing
Signs you need it
Bedrooms facing flight paths where LAWA windows helped but low-frequency rumble still penetrates, or home offices where exterior noise disrupts calls, suggest wall mass is insufficient.
What it costs in Inglewood
Interior wall soundproofing with Rockwool Safe’n’Sound and resilient channel in Inglewood generally costs $3,500-$7,500 per room, depending on square footage and electrical outlet relocation.
How we do it
We furr out existing drywall with resilient channel, fill cavities with Rockwool, seal perimeters with acoustic caulk, and deliver STC improvement estimates based on assembly - not guesses.
What Wall Insulation Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Drill-and-fill wall insulation (dense-pack) | $2,500-$5,500 |
| Interior wall soundproofing (per room) | $3,500-$7,500 |
| Exterior wall insulation (full removal and retrofit) | $6,000-$12,000 |
Will drilling holes damage my stucco exterior?
We drill 2-inch holes and patch with color-matched stucco - the repair is included in the written scope, and we photograph before and after. Call (424) 704-9866 for a free inspection.
Can wall insulation help with LAX noise after the sound program?
Yes - adding mass and damping to exterior walls addresses the low-frequency noise that acoustic windows alone cannot stop, a common finding in our Inglewood inspections.
Attic Cleaning & Rodent Proofing in Inglewood
Inglewood’s mature tree canopy and older housing stock create ideal conditions for roof rat activity, and post-war attics with unsealed eaves and vent screens offer easy entry. The marine layer keeps attics humid enough that rodent waste degrades air quality quickly once infestation begins. Attic Cleaning & Rodent Proofing follows our standard sequence: remove, sanitize, exclude, document - never skip a step.
Attic Sanitizing & Decontamination
Signs you need it
Visible rodent droppings, urine stains on insulation or drywall, or a persistent organic odor from the attic hatch indicate active or recent infestation requiring professional decontamination.
What it costs in Inglewood
Attic sanitizing and decontamination in Inglewood typically runs $1,500-$3,500, including HEPA vacuuming, enzymatic treatment, and disposal of contaminated material.
How we do it
We suit in full PPE, HEPA-vacuum all surfaces, apply enzyme neutralizer to organic waste, and deliver a Documented Photo Record of the sanitized deck before any new insulation is discussed.
Rodent Proofing & Exclusion
Signs you need it
Scratching noises at night, gnaw marks on eaves or vent screens, or recurring droppings after cleaning mean entry points remain open and re-infestation is certain.
What it costs in Inglewood
Rodent proofing and exclusion in Inglewood generally costs $1,200-$3,000, including metal flashing at eaves, hardware cloth over vents, and sealant at all penetrations.
How we do it
We inspect the roof perimeter and soffits, install 1/4-inch hardware cloth over vents, flash eaves with galvanized metal, and seal all gaps larger than 1/4 inch - then photograph every exclusion point.
What Attic Cleaning & Rodent Proofing Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Attic sanitizing and decontamination | $1,500-$3,500 |
| Rodent proofing and exclusion | $1,200-$3,000 |
| Full attic restoration (cleaning + proofing + reinsulation) | $4,500-$9,500 |
How do I know if rodents are in my Inglewood attic right now?
Listen for scratching after dark, check the attic for fresh droppings, and look for gnaw marks on eaves - if you find any, call (424) 704-9866 before insulation work begins.
Will rodent proofing keep them out permanently?
Our exclusion work carries the 365-Day Done Right Promise - if rodents re-enter through any point we sealed, we return and fix it at no charge.
Home Energy Audit in Inglewood
Inglewood’s post-war homes were built without energy codes, and the patchwork of partial upgrades - LAWA windows here, a new HVAC there - often masks the underlying envelope failures that drive bills. A home energy audit identifies the specific leaks, insulation gaps, and moisture paths that waste conditioned air. Home Energy Audit is where we start when a homeowner wants to know what to fix first, not just what to buy.
Blower Door Test
Signs you need it
Rooms that are never comfortable, high utility bills despite moderate Inglewood temperatures, or a home that felt fine until recent work was done suggest hidden envelope leakage.
What it costs in Inglewood
A standalone blower-door test in Inglewood typically runs $350-$650, or is included as part of a comprehensive energy audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - the single number that tells us how much air the envelope is losing.
Thermal Imaging Inspection
Signs you need it
Cold spots on ceilings in winter, hot spots on exterior walls in summer, or moisture stains that appear without roof leaks indicate insulation voids or air leakage visible only with infrared.
What it costs in Inglewood
Thermal imaging inspection in Inglewood generally costs $400-$800 as a standalone service, or bundled with blower-door testing in a full audit.
How we do it
We scan the building envelope with a FLIR camera during controlled conditions, mark anomalies on digital images, and correlate findings with the blower-door result for a prioritized repair list.
What Home Energy Audit Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Blower-door test (standalone) | $350-$650 |
| Thermal imaging inspection | $400-$800 |
| Comprehensive home energy audit | $600-$1,200 |
What does a home energy audit include in Inglewood?
A comprehensive audit includes blower-door testing, thermal imaging, insulation inspection, and duct leakage testing - you receive a written report with prioritized recommendations and a written price for each. Call (424) 704-9866 to schedule.
