Insulation in Irvine, CA
Crawl space encapsulation and vapor barrier installation in Irvine typically runs $3,200-$6,800 for a full encapsulation, with most jobs completed in one to two days. Because Irvine’s master-planned villages were built in concentrated waves, the crawl spaces we encounter follow predictable patterns: 1970s-80s homes in Woodbridge and University Park often have bare dirt floors with no vapor barrier at all, while newer construction in Great Park Neighborhoods may have thin 6-mil poly that’s already failing. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in. Call (657) 286-7673 for a written price before any work starts.
Why Irvine Homes Are Different
Irvine’s housing stock isn’t random. The Irvine Company built entire villages from near-identical plans in tight construction windows, which means insulation problems cluster by neighborhood era rather than scattering house by house. In Woodbridge, when we find R-8 settled fiberglass in one attic, the next three doors down have the same issue.
The Saddleback Valley funnel makes Irvine significantly hotter than coastal Orange County during Santa Ana wind events, with fall temperatures regularly hitting the upper 90s to low 100s. That thermal load exposes every degree of under-performance in aging attic insulation. Meanwhile, the city’s unusually high share of attached condos and townhomes in Quail Hill, Portola Springs, and Great Park Neighborhoods sustains demand for shared-wall sound and thermal control that most Orange County markets cannot match. Many of these newer communities also operate under HOA maintenance standards that specify approved materials and installation methods.
Our Main Irvine Services
Most calls from Irvine homeowners center on attic performance and dense-pack solutions. Here’s where those jobs live on our site:
Spray Foam Insulation in Irvine
Spray foam insulation in Irvine is the right choice for complex rooflines, conditioned attics, and sound control in attached townhomes where fire-rated assemblies are required. We specify open-cell Icynene for above-deck applications and closed-cell Demilec for crawl spaces and rim joists. Every spray foam job includes a written scope, documented photos, and the 365-Day Done Right Promise. Spray Foam Insulation in Irvine details our process and pricing.
Blown-In Insulation in Irvine
Blown-in insulation in Irvine is the most common retrofit for 1970s-80s tract homes with open attics and minimal existing material. We use GreenFiber cellulose or Johns Manville fiberglass, blown to Title 24-compliant depth after air sealing is complete. The blower-door test confirms we didn’t just add insulation but actually reduced leakage. Blown-In Insulation in Irvine explains our density and coverage standards.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Irvine
Irvine’s older villages, particularly Woodbridge and University Park, were built with vented crawl spaces and bare dirt floors that allow ground moisture to rise into floor framing. During Santa Ana events, that humid air gets pulled upward into living spaces, accelerating mold risk and forcing HVAC systems to work harder. Newer attached homes in Quail Hill and Portola Springs often have thin 6-mil polyethylene that’s already torn or displaced. We provide Crawl Space Encapsulation & Vapor Barrier as a complete system, not a membrane-only fix.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare dirt or torn plastic, and you notice musty odors or cupping hardwood floors above.
What it costs in Irvine
A ground-only vapor barrier installation in Irvine typically runs $1,800-$3,400 depending on square footage and access.
How we do it
We remove debris, grade the floor, lay 12-20 mil reinforced polyethylene with sealed seams, and extend it 6 inches up foundation walls.
Crawl Space Encapsulation
Signs you need it
You’re seeing condensation on ductwork, mold on floor joists, or energy bills that spike despite recent HVAC service.
What it costs in Irvine
Full crawl space encapsulation in Irvine, including walls and conditioning, typically ranges from $3,200-$6,800.
How we do it
We seal all vents, install rigid foam board on walls, apply vapor barrier across floor and walls, add a dehumidifier, and provide before-and-after moisture readings.
What Crawl Space Encapsulation & Vapor Barrier Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Ground vapor barrier only | $1,800 - $3,400 |
| Full encapsulation with wall insulation | $3,200 - $6,800 |
| Dehumidifier installation | $1,200 - $2,400 |
How long does crawl space encapsulation take in Irvine?
Most jobs finish in one to two days. We bring all materials to the site and do not leave until the vapor barrier is fully sealed and documented.
Will encapsulation help with summer cooling costs in Irvine?
Yes. Sealing a vented crawl space stops hot, humid air from being drawn into your home during Santa Ana events, which reduces the load on your air handler. Call (657) 286-7673 for a written price and blower-door assessment.
Radiant Barrier Installation in Irvine
Irvine’s inland position in the Saddleback Valley creates intense attic heat loads during fall Santa Ana events, with roof deck temperatures regularly exceeding 150°F in unshaded homes. The original 1970s-80s villages of Woodbridge and University Park were built without any radiant barrier, and their dark composite shingle roofs absorb and re-radiate that heat directly into attic insulation that was already underperforming. We install Radiant Barrier Installation as a standalone retrofit or paired with air sealing and insulation upgrades.
Attic Radiant Barrier
Signs you need it
Your attic feels like a furnace by 10 a.m., your upstairs rooms stay hot past midnight, and your AC runs continuously during Santa Ana weeks.
What it costs in Irvine
Attic radiant barrier installation in Irvine typically runs $1,400-$2,800 for a standard single-story home.
How we do it
We staple perforated foil across rafter bays, maintaining ventilation channels, and verify installation with infrared imaging to confirm no gaps.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing a 1970s-80s Irvine tract home and want to address the primary heat gain path before new shingles go on.
What it costs in Irvine
Roof-deck radiant barrier applied during re-roofing in Irvine typically adds $1,800-$3,200 to the project.
How we do it
We apply reflective sheathing or foil-faced decking to the exposed roof deck before shingle installation, integrated with your roofing contractor’s schedule.
What Radiant Barrier Installation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Attic radiant barrier (retrofit) | $1,400 - $2,800 |
| Roof-deck barrier during re-roof | $1,800 - $3,200 |
| Radiant barrier with air sealing package | $2,600 - $4,400 |
Does radiant barrier work with existing insulation in Irvine?
Yes, but it’s most effective when paired with air sealing and adequate insulation depth. We measure your current R-value and leakage before recommending barrier-only versus full envelope work.
How much cooler will my attic get with a radiant barrier in Irvine?
Attic temperatures typically drop 20-35°F during peak sun hours. The exact reduction depends on roof color, pitch, and existing ventilation. Call (657) 286-7673 for a thermal imaging assessment and written price.
Insulation Removal & Replacement in Irvine
The concentrated construction waves in Irvine’s older villages mean we regularly encounter attics with 40-50 years of accumulated fiberglass, rodent debris, and failed vapor barriers in Woodbridge, University Park, and Turtle Rock. Santa Ana heat events bake this material into a compacted, dusty mat that performs closer to R-8 than its original R-19 label. We provide Insulation Removal & Replacement with full containment, HEPA filtration, and documented disposal.
Contaminated Insulation Removal
Signs you need it
Your attic insulation smells musty, shows rodent droppings, or was saturated by a past roof leak that was fixed but never cleaned up.
What it costs in Irvine
Contaminated insulation removal in Irvine typically runs $2,400-$4,200 depending on square footage and contamination level.
How we do it
We install negative-air containment, remove material with HEPA-filtered vacuums, bag and dispose per Orange County waste regulations, and provide photos of the clean deck.
Insulation Replacement
Signs you need it
Your original fiberglass has settled below joist tops, you’re experiencing temperature swings between rooms, and your energy bills have climbed despite stable rates.
What it costs in Irvine
Full insulation replacement with new material in Irvine typically ranges from $3,600-$6,400 for a standard attic.
How we do it
We air seal the entire attic floor, install baffles at eaves, and blow new Johns Manville or Knauf fiberglass to current Title 24 depth with density verification.
What Insulation Removal & Replacement Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Contaminated insulation removal | $2,400 - $4,200 |
| Standard insulation removal (non-contaminated) | $1,600 - $2,800 |
| Removal + replacement with air sealing | $3,600 - $6,400 |
Do I have to leave my house during insulation removal in Irvine?
No. Our containment and negative-air systems keep living spaces isolated. Most homeowners stay home during the removal phase and return to normal activity the same evening.
How do I know if my old insulation is hazardous?
We inspect for asbestos-containing vermiculite, rodent-borne pathogens, and mold during our initial assessment. If hazardous material is suspected, we coordinate third-party lab testing before disturbing anything. Call (657) 286-7673 for a documented inspection and written price.
Attic Air Sealing in Irvine
In Irvine’s 1970s-80s villages, the same construction crews built dozens of homes using identical framing details, which means the same air leakage paths repeat block after block. Top plates, can light housings, and duct boots were rarely sealed in original construction, and decades of Santa Ana pressurization have pulled conditioned air through these gaps continuously. We provide Attic Air Sealing as a standalone service or mandatory first step before any insulation work, with blower-door verification on every job.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at interior wall tops, your blower-door test shows excessive leakage, or your attic insulation is blackened along framing edges from filtered air.
What it costs in Irvine
Top plate and penetration sealing in Irvine typically runs $1,800-$3,200 for a standard single-story home.
How we do it
We expose top plates at the attic floor line, seal all gaps with fire-rated caulk and foam, address wire and pipe penetrations, and retest with the blower door to confirm reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed can lights flicker in wind, your ducts show dust streaks at connections, or rooms farthest from the air handler never reach set temperature.
What it costs in Irvine
Can light and duct boot sealing in Irvine typically ranges from $1,200-$2,400 depending on fixture count and duct configuration.
How we do it
We install fire-rated covers over non-IC cans, seal with mastic at duct boots, and verify with pressure pan testing to confirm each register is receiving designed airflow.
What Attic Air Sealing Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Top plate & penetration sealing | $1,800 - $3,200 |
| Can light & duct boot sealing | $1,200 - $2,400 |
| Full attic air sealing package | $2,800 - $4,600 |
Can air sealing alone reduce my energy bills in Irvine?
Yes, typically 10-20% in homes with significant leakage. We document the before-and-after blower-door reading so you can see the exact CFM50 reduction you paid for.
Do you need to remove insulation to seal my attic in Irvine?
We can often work around existing insulation by lifting sections and replacing them, but settled or contaminated material may need removal first. We assess this during our initial inspection and include the determination in your written scope. Call (657) 286-7673 for a blower-door test and written price.
Wall Insulation in Irvine
Irvine’s attached townhomes and condos in Quail Hill, Portola Springs, and Great Park Neighborhoods were built with shared walls that meet fire and sound codes but often underperform on thermal comfort and noise transfer. The 1970s-80s detached homes in Woodbridge and University Park frequently have empty exterior wall cavities or thin R-11 batts that settled within years of installation. We provide Wall Insulation using injection foam and dense-pack methods that don’t require interior demolition.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, your home was built before 1990, or prior infrared inspection shows empty cavities in framed walls.
What it costs in Irvine
Injection foam wall insulation in Irvine typically runs $3,200-$5,800 for a standard single-story home depending on cavity count and access.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam that fills without bowing drywall, patch and texture match, and provide thermal imaging confirmation of complete fill.
Interior Wall Soundproofing
Signs you need it
You hear conversations, footsteps, or plumbing noise through shared walls in your Irvine townhome, and your HOA restricts structural modifications.
What it costs in Irvine
Interior wall soundproofing with Rockwool or dense-pack cellulose in Irvine typically ranges from $2,400-$4,200 per treated wall.
How we do it
We access walls through minimal openings, install fire-rated sound-dampening batts or dense-pack cellulose, seal all penetrations with acoustic caulk, and verify with STC rating improvement documentation.
What Wall Insulation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Injection foam (exterior walls) | $3,200 - $5,800 |
| Interior wall soundproofing | $2,400 - $4,200 per wall |
| Drill & fill with cellulose | $2,800 - $4,800 |
Will wall insulation damage my drywall in Irvine?
Our injection and drill-fill methods require only small access holes that we patch and texture-match. In most cases, repainting is the only finish work needed.
Can you insulate walls in an Irvine condo with HOA restrictions?
Yes. We work within HOA maintenance standards, use fire-rated materials that meet California building code, and provide the documentation your association may require. Call (657) 286-7673 for a written scope and material specification sheet.
Attic Cleaning & Rodent Proofing in Irvine
Irvine’s mature landscaping in Woodbridge and University Park creates continuous canopy corridors that allow roof rats and squirrels to access attics without touching ground, and the original 1970s-80s construction left generous gaps at eaves and vents that have never been addressed. Santa Ana heat then bakes rodent debris and urine into attic insulation, creating odor and respiratory issues that persist until the source is fully removed and excluded. We provide Attic Cleaning & Rodent Proofing as a complete system: cleanout, sanitizing, proofing, and documentation.
Attic Sanitizing & Decontamination
Signs you need it
Your attic smells of ammonia or musk, you’ve found droppings or nesting material, or your HVAC intake draws from a contaminated attic space.
What it costs in Irvine
Attic sanitizing and decontamination in Irvine typically runs $2,200-$3,800 depending on contamination extent and attic square footage.
How we do it
We remove all contaminated material, apply enzyme-based sanitizer to affected surfaces, run HEPA air scrubbers until particulate counts normalize, and provide before-and-after photos with lab-verified clearance.
Rodent Proofing & Exclusion
Signs you need it
You’re hearing scratching at night, seeing gnaw marks at eaves, or finding new droppings within months of prior pest control treatment.
What it costs in Irvine
Rodent proofing and exclusion in Irvine typically ranges from $1,600-$3,200 for a standard home with accessible eaves and vents.
How we do it
We seal all entry points with rodent-proof materials, install hardware cloth over vents, replace damaged fascia, and provide a written warranty with photo documentation of every sealed location.
What Attic Cleaning & Rodent Proofing Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Attic sanitizing & decontamination | $2,200 - $3,800 |
| Rodent proofing & exclusion | $1,600 - $3,200 |
| Full attic restoration (cleanout + proofing + re-insulation) | $4,800 - $8,400 |
How do I know rodents are gone before you re-insulate my Irvine attic?
We install temporary one-way exits at active entry points and monitor for 7-10 days before sealing permanently. No insulation goes in until we confirm zero activity.
Will my homeowner’s insurance cover rodent damage in Irvine?
Most policies exclude rodent damage, but we document everything with photos and written scope in case your carrier makes an exception. We also provide the proofing documentation that insurers increasingly require for future coverage. Call (657) 286-7673 for a contamination assessment and written price.
Home Energy Audit in Irvine
A home energy audit in Irvine reveals why identical floor plans in the same village can have vastly different utility bills. The 1970s-80s construction waves left consistent air leakage paths, but decades of owner modifications, roof replacements, and HVAC changes have created uneven performance that only pressure testing and thermal imaging can map accurately. We provide Home Energy Audit as a standalone diagnostic or the first step in any envelope upgrade, with every finding documented in a written report you can use for contractor comparison or rebate applications.
Blower Door Test
Signs you need it
Your energy bills are rising without rate changes, rooms have persistent temperature differences, or you’re considering insulation work and want a baseline before spending.
What it costs in Irvine
A standalone blower-door test in Irvine typically runs $350-$550, or it’s included at no charge when bundled with a proposal for envelope work.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure total leakage in CFM50, and identify dominant leakage paths with smoke pencils and infrared cameras.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls, you’re buying a home in an older Irvine village, or your HVAC technician cannot explain why one zone never reaches temperature.
What it costs in Irvine
Thermal imaging inspection in Irvine typically ranges from $250-$450 as a standalone service, or combined with blower-door testing for $450-$750 total.
How we do it
We scan all building surfaces with a FLIR camera during controlled temperature differential conditions, mark thermal anomalies on photos, and correlate findings with construction era and typical village defects.
What Home Energy Audit Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Blower-door test (standalone) | $350 - $550 |
| Thermal imaging inspection | $250 - $450 |
| Full audit (blower door + thermal + insulation inspection + written report) | $450 - $750 |
How long does a home energy audit take in Irvine?
Most audits require 2-3 hours on site, with the written report delivered within 48 hours. We schedule during temperature-differential conditions for valid thermal imaging.
Can I use my audit for California energy rebates?
Yes. Our reports meet documentation requirements for SCE and SoCalGas rebate programs, and we note qualifying measures with estimated savings. Call (657) 286-7673 to schedule and receive your written scope and price for any recommended work.

What Irvine 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.
