Insulation in Irvine, CA
Crawl space encapsulation and vapor barrier installation in Irvine typically runs $2,800-$6,500 for most homes, with full encapsulations reaching $8,000-$12,000 in larger properties with complex access. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in, publishing before-and-after blower-door numbers on every applicable job so you can verify the performance change. In Irvine’s master-planned villages, where the Irvine Company used repeating construction templates across entire neighborhoods, we can often diagnose envelope problems from the street and confirm them with a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your home is losing. Call (562) 526-6978 for a written price before any work starts.
Why Irvine Homes Are Different
Irvine’s residential neighborhoods were built almost entirely by the Irvine Company in master-planned village phases, creating block-by-block uniformity in construction era and methods. The 1970s-80s villages - University Park, Turtle Rock, and Woodbridge - were framed under early or pre-Title 24 standards with original R-11 wall batts and compacted fiberglass attic insulation that now falls far below current California energy code. This means an insulation contractor who knows one home in a 1970s Irvine village knows the deficiencies of virtually every home on that street.
Irvine sits in an inland coastal valley sheltered enough from the ocean that summer afternoon highs regularly reach 90-95°F while mornings stay in the 60s - a wide daily swing that makes attic insulation and air-sealing critical for managing cooling loads on central A/C systems. Fall Santa Ana wind events drive hot, dry air through poorly sealed attic bypasses and wall penetrations, compounding energy loss in homes that were never tightly air-sealed to begin with. Because the Irvine Company used repeating framing templates within each village, attic hatch placements, rafter depths, and original batt thicknesses are nearly identical home to home in 1970s neighborhoods - a local contractor blowing in attic insulation in Turtle Rock can pre-cut materials and set machine settings before pulling into the driveway.
Our Main Irvine Services
Most Irvine homeowners who call us start with attic work or spray foam. Here is what those jobs involve here.
Attic Insulation in Irvine
In University Park and Woodbridge, we regularly find original fiberglass batts compressed to half their labeled R-value after 40-50 years of settling and foot traffic from cable installers. We remove the degraded material, seal top plates and can lights, then install new insulation to current Title 24 standards with a documented photo record and blower-door verification. Attic Insulation in Irvine covers the full scope and pricing.
Spray Foam Insulation in Irvine
Portola Springs and Stonegate homes with complex rooflines and conditioned attic spaces often need open-cell or closed-cell spray foam to create a continuous air barrier at the roof deck. We specify Demilec or Icynene products, never proprietary foam, and provide a written scope with coverage depths and R-value targets before anyone starts. Spray Foam Insulation in Irvine has the details.
Blown-In Insulation in Irvine
For Woodbridge townhomes and Turtle Rock single-family homes with straightforward attic floors, blown-in fiberglass or cellulose is the most cost-effective path to code compliance. We pre-seal all penetrations, set damming at recessed lights, and blow to a measured, even depth with GreenFiber or Owens Corning material. Blown-In Insulation in Irvine explains the process and what it costs.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Irvine
Irvine’s older villages sit on expansive clay soils that wick moisture into vented crawl spaces year-round, while the marine layer and occasional winter rains keep relative humidity elevated even in dry months. Homes in Turtle Rock and University Park with original foundation vents and no ground cover routinely show wood moisture content above 20 percent, the threshold for fungal growth and structural decay. Crawl Space Encapsulation & Vapor Barrier is the permanent fix: we seal the ground and walls, control humidity, and stop the moisture cycle that damages floor joists and indoor air quality.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare dirt or thin polyethylene sheeting with standing water after rain, and indoor humidity stays above 60 percent even with the A/C running.
What it costs in Irvine
A 6-mil to 20-mil vapor barrier installation for a typical Irvine crawl space runs $2,800-$4,500, depending on access clearance and whether we need to remove old, degraded sheeting first.
How we do it
We remove debris and old plastic, lay overlapping seams of reinforced polyethylene, seal to foundation walls with butyl tape, and install mechanical fasteners at edges so the barrier stays put when inspectors or plumbers crawl through.
Crawl Space Encapsulation
Signs you need it
You smell mustiness in ground-floor rooms, your hardwood floors cup at the edges, or your HVAC ducts in the crawl space show corrosion on the exterior insulation jacket.
What it costs in Irvine
Full encapsulation with closed-cell foam on walls, sealed rim joists, and a dehumidifier typically ranges $8,000-$12,000 for Irvine homes under 2,500 square feet, with larger or multi-zone systems reaching $15,000.
How we do it
We seal foundation vents, apply closed-cell foam to walls and rim joists, install a permanent vapor barrier across the ground, and size a condensate-pumped dehumidifier to maintain 50-55 percent relative humidity with a hygrometer readout you can check.
What Crawl Space Encapsulation & Vapor Barrier Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Vapor barrier (ground only) | $2,800 - $4,500 |
| Partial encapsulation (walls + ground) | $5,500 - $8,500 |
| Full encapsulation with dehumidifier | $8,000 - $12,000 |
Do I need a permit for crawl space work in Irvine?
Irvine requires a building permit for any structural modification to foundation vents or for electrical work powering dehumidifiers; vapor barrier-only installations typically do not trigger permitting. We handle permit applications as part of our written scope when required, and you receive the approved documentation for your HOA file.
How long does crawl space encapsulation take in Irvine?
Most vapor barrier jobs finish in one day; full encapsulations with foam and dehumidifier installation take two to three days, with no overnight crew presence. We coordinate access with your schedule and provide a Documented Photo Record of each phase before we close.
Radiant Barrier Installation in Irvine
Irvine’s tile-roofed homes in Portola Springs, Stonegate, and the Great Park Neighborhoods absorb intense afternoon solar gain through their roof decks, pushing attic temperatures past 140°F even when outdoor highs are only in the 90s. The original radiant barrier foil, if installed at all during construction, often degrades or was omitted entirely in early-phase builds, leaving HVAC ducts and air handlers to cook in unconditioned attic space. Radiant Barrier Installation reflects radiant heat before it enters the living envelope, reducing cooling load and extending equipment life in a climate where A/C runs six months a year.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms are 8-12°F warmer than downstairs by late afternoon, or your A/C supply air feels lukewarm by the time it reaches the far vents.
What it costs in Irvine
Radiant barrier foil stapled to rafters or laid over existing attic insulation in a typical Irvine home runs $1,800-$3,200, with costs rising for steep-pitch roofs or limited attic access.
How we do it
We install perforated, double-sided aluminum foil across rafter bays or drape it over the attic floor, maintaining ventilation channels and avoiding compression of existing insulation, then photograph the completed layout for your record.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and the decking is exposed, or your current shingles are failing prematurely from excessive attic heat cycling.
What it costs in Irvine
Radiant barrier roof decking or spray-applied radiant coating during re-roofing typically adds $2,500-$4,800 to the roofing contract, depending on square footage and decking replacement needs.
How we do it
We coordinate with your roofing contractor to install OSB with factory-applied radiant barrier laminate or spray a low-emissivity coating directly to clean decking before new underlayment goes down, with a written scope defining who handles what.
What Radiant Barrier Installation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Foil radiant barrier (attic install) | $1,800 - $3,200 |
| Radiant barrier roof deck (with re-roof) | $2,500 - $4,800 |
| Spray-applied radiant coating | $3,000 - $5,500 |
Does radiant barrier work with tile roofs in Irvine?
Yes, and it’s particularly effective because tile roofs have minimal inherent insulation value and high thermal mass that radiates heat into the attic long after sunset; radiant barrier interrupts that transfer. We see 20-30 percent reduction in attic peak temperatures in monitored Irvine homes.
Can radiant barrier be added without removing insulation?
Yes, we staple foil to rafters or install it as a draped layer over existing batts or blown-in, provided we first verify that current insulation depth meets minimum code and is not contaminated. Call (562) 526-6978 for an exact quote - estimates are free.
Insulation Removal & Replacement in Irvine
Homes in Woodbridge and University Park built in the 1970s and 1980s often contain fiberglass batts that have settled, been disturbed by trades, or been contaminated by rodent activity over four decades. The original R-11 wall insulation and attic batts perform well below modern Title 24 requirements, and in some cases harbor odors or pathogens that affect indoor air quality. Insulation Removal & Replacement starts with safe extraction, proper disposal, and air sealing before any new material goes in, so you don’t insulate over problems.
Attic Insulation Removal
Signs you need it
Your attic insulation is visibly compressed, discolored, or has rodent droppings throughout, or you smell urine or mustiness that intensifies when the HVAC runs.
What it costs in Irvine
Removal and disposal of attic insulation in a typical Irvine home runs $1,500-$3,000, with HEPA-contained vacuuming adding $800-$1,500 if significant dust or debris is present.
How we do it
We set up negative-air containment, remove material with industrial vacuum equipment into sealed bags, dispose at licensed facilities, and provide photos of the clean deck before any sealing or replacement begins.
Contaminated Insulation Removal
Signs you need it
You’ve had rodent or bird infestation in the attic, or testing reveals elevated bacteria or fungal spores in the insulation layer.
What it costs in Irvine
Contaminated removal with full PPE, HEPA filtration, and antimicrobial treatment of the substrate typically ranges $3,500-$6,000 for Irvine homes, depending on contamination extent and attic square footage.
How we do it
We suit in full protective gear, establish negative pressure, remove and bag contaminated material, apply enzyme-based sanitizer to exposed wood, and hold the space dry until clearance testing or new insulation installation proceeds.
What Insulation Removal & Replacement Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Standard attic insulation removal | $1,500 - $3,000 |
| HEPA-contained removal | $2,300 - $4,500 |
| Contaminated removal + sanitizing | $3,500 - $6,000 |
Is it cheaper to remove insulation myself in Irvine?
DIY removal risks exposure to rodent-borne pathogens, asbestos in pre-1990 vermiculite, and improper disposal at Orange County facilities that require documentation. We carry the licensing and disposal contracts, and our price includes the documented photo record and written warranty.
How long does insulation removal take?
Most attic removals finish in one day; contaminated jobs with sanitizing take two days. We schedule so you’re never without insulation overnight in winter or peak summer - call (562) 526-6978 to coordinate timing.
Attic Air Sealing in Irvine
The repeating framing templates in Irvine’s 1970s villages mean the same air leaks appear in nearly every home: top plates unsealed at the wall-to-attic transition, can lights cutting through fire-rated drywall without gaskets, and duct boots pulling conditioned air directly into the vented attic. Fall Santa Ana winds pressurize these bypasses, accelerating both energy loss and dust infiltration. Attic Air Sealing is the foundational step we complete before any insulation goes in, with blower-door verification to prove the result.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at outlet boxes on exterior walls, or your blower-door test shows excessive leakage at the attic floor plane despite adequate insulation depth.
What it costs in Irvine
Sealing top plates, wire penetrations, and plumbing stacks in a typical Irvine attic runs $1,200-$2,400, with costs rising if we need to move stored items or work around complex HVAC routing.
How we do it
We locate every top plate and penetration with blower-door-guided smoke, seal with fire-rated caulk and expanding foam, install baffles to maintain soffit ventilation, and retest to document the CFM50 reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights flicker in windy conditions, or you see dusty streaks on ceiling drywall around the trim rings indicating attic air is being pulled through.
What it costs in Irvine
Sealing accessible can lights with fire-rated covers and mastic-sealing duct boots typically adds $800-$1,800 to the air-sealing scope, depending on fixture count and duct configuration.
How we do it
We install pre-formed fire-rated enclosures over each can light, seal with fire-stop caulk, apply mastic - a thick, permanent sealant - to all duct connections and boots, and verify with pressure pan testing during the blower-door run.
What Attic Air Sealing Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Top plate & penetration sealing | $1,200 - $2,400 |
| Can light & duct boot sealing | $800 - $1,800 |
| Full attic air sealing package | $2,500 - $4,500 |
Will air sealing make my attic too hot?
No, we maintain all required soffit-to-ridge ventilation paths with baffles and never seal exhaust vents or intentional airflow; what we stop is unconditioned air moving through the ceiling plane, not through the attic itself. Your attic temperature stays within normal ranges.
Do you need to remove insulation to air seal?
We can often work around existing insulation by lifting sections, sealing underneath, and replacing it; if the insulation is degraded, we recommend removal first so we can seal the full deck and photograph the work. Call (562) 526-6978 and we’ll assess which path makes sense for your home.
Wall Insulation in Irvine
The original R-11 fiberglass batts in University Park, Turtle Rock, and Woodbridge walls were installed before Title 24 tightened thermal requirements, and many have settled or were never in full contact with the studs. In Portola Springs and newer villages, stucco-over-wood-frame construction with 2×4 walls still limits cavity depth, but dense-pack cellulose or injection foam can achieve effective R-values without invasive demolition. Wall Insulation improves comfort in rooms that never seem to hold temperature and reduces the noise transmission common in Irvine’s attached townhome products.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, or you can hear neighbor conversations through shared townhome walls that should be private.
What it costs in Irvine
Injection foam for a typical Irvine single-story home runs $3,500-$6,500, with townhome shared-wall treatments at $2,000-$4,000 per unit depending on linear footage and access.
How we do it
We drill 5/8-inch holes at stud-bay intervals, inject slow-rise foam that fills without bowing drywall, patch with matching texture, and provide a thermal scan to verify complete cavity fill before we close.
Drill & Fill Wall Insulation
Signs you need it
Your walls have no insulation at all, confirmed by outlet removal or thermal imaging, or you’re remodeling and have temporary access to open cavities.
What it costs in Irvine
Dense-pack cellulose drill-and-fill for a complete Irvine home typically ranges $2,800-$5,200, with costs lower if we’re coordinating with a concurrent exterior repaint that covers patchwork.
How we do it
We drill at the top of each bay, blow cellulose to calculated density with a fill tube that reaches the bottom plate, verify with weight-per-bag tracking, and patch holes to match existing texture or prepare for your painter.
What Wall Insulation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Injection foam (single-story home) | $3,500 - $6,500 |
| Dense-pack drill & fill | $2,800 - $5,200 |
| Shared townhome wall treatment | $2,000 - $4,000 |
Can you insulate walls without removing drywall?
Yes, injection foam and dense-pack cellulose both install through small exterior or interior holes that we patch and texture-match; the only drywall removal is for outlet and switch cutouts we use for access. Most homes are fully finished in two days.
Does wall insulation help with sound in Irvine townhomes?
Yes, dense-pack cellulose at proper density reduces airborne sound transmission through shared walls by 8-12 decibels, a noticeable improvement for adjacent units in Woodbridge or Northwood townhome clusters. Call (562) 526-6978 for a written price on your specific wall configuration.
Attic Cleaning & Rodent Proofing in Irvine
Irvine’s mature landscaping and interconnected greenbelts create continuous wildlife corridors that terminate in warm, undisturbed attics, particularly in older villages with deteriorated eave screens and vent gaps. Once rodents establish access, they compress insulation for nesting, contaminate it with urine and droppings, and create entry points for successive generations. Attic Cleaning & Rodent Proofing removes the contamination, seals the access paths, and restores the attic to a clean, inspectable condition with photo documentation.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at dawn or dusk, find droppings in the attic or insulation, or notice insulation displaced into troughs and tunnels.
What it costs in Irvine
Attic cleanout with HEPA vacuuming, removal of contaminated insulation, and enzyme sanitizing typically runs $2,500-$4,500 for Irvine homes, with full restoration including new insulation quoted separately.
How we do it
We remove all insulation and debris with negative-air containment, HEPA-vacuum exposed surfaces, apply botanical enzyme treatment that breaks down organic contamination, and leave the space dry and photographed before any proofing or re-insulation.
Rodent Proofing & Exclusion
Signs you need it
You’ve had recurring rodent activity despite trapping, or you can see daylight through eave vents, pipe penetrations, or roof junction gaps from inside the attic.
What it costs in Irvine
Comprehensive rodent proofing with galvanized mesh, concrete patching, and vent screening for a typical Irvine home ranges $1,800-$3,500, with warranty terms written into the scope.
How we do it
We inspect every potential entry with a focused light, seal gaps with rodent-proof materials - never foam alone - install custom-fit vent screens, and provide a written exclusion map showing every location addressed.
What Attic Cleaning & Rodent Proofing Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Attic cleanout & sanitizing | $2,500 - $4,500 |
| Rodent proofing & exclusion | $1,800 - $3,500 |
| Full restoration (cleanout + proofing + insulation) | $5,500 - $9,000 |
How do I know rodents are gone before you re-insulate?
We require a 7-14 day no-activity period confirmed by you or your pest control provider, and we seal all access points before installing new insulation so re-entry is structurally prevented; our proofing carries a written warranty under the 365-Day Done Right Promise.
Will my HOA allow rodent proofing work?
Most Irvine HOAs require advance notice for exterior ladder work and vent modifications, but rodent proofing is generally approved as maintenance; we provide the written scope and photo documentation your HOA manager typically requests. Call (562) 526-6978 and we’ll coordinate the paperwork.
Home Energy Audit in Irvine
With utility rates among the highest in the continental U.S. and summer cooling loads driven by 90°F afternoons and intense roof-deck radiant gain, Irvine homeowners need precise data on where conditioned air escapes and where insulation falls short. A blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - cuts through guesswork and identifies the specific leaks that drive your bills. Home Energy Audit gives you a prioritized scope with written pricing for each improvement, so you can phase work or proceed all at once with full information.
Blower Door Test & Thermal Imaging
Signs you need it
Your energy bills are 30 percent or more above comparable homes in your village, or rooms on the same thermostat zone vary by more than 5°F.
What it costs in Irvine
A comprehensive blower-door test with thermal imaging scan for a typical Irvine home runs $400-$700, with the fee credited toward any work we perform within 90 days.
How we do it
We install a calibrated fan in an exterior door, depressurize to 50 Pascals, use smoke pencils and an infrared camera to map leakage paths, and deliver a written report with CFM50 before-and-after targets for each proposed seal.
Duct Leakage Test
Signs you need it
Your A/C runs constantly but cooling is uneven, or your ducts run through a vented attic and are original to a 1970s-80s build.
What it costs in Irvine
Duct leakage testing with a duct blaster, separate from the blower-door test, typically adds $250-$450 to the audit scope, or $550-$950 combined with thermal imaging.
How we do it
We seal all supply and return registers, pressurize the duct system with a calibrated fan, measure leakage as a percentage of system airflow, and pinpoint accessible leaks with smoke for repair prioritization.
What Home Energy Audit Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Blower-door test + thermal imaging | $400 - $700 |
| Duct leakage test (standalone) | $250 - $450 |
| Combined comprehensive audit | $550 - $950 |
Is an energy audit required before insulation work in Irvine?
No, but we recommend it for homes built before 1990 because the audit often reveals that air sealing delivers more comfort per dollar than additional insulation alone; we never sell insulation over an unsealed attic floor. The audit fee applies to your project if we do the work.
What do I receive after the audit?
You get a written report with blower-door and thermal images, a prioritized scope with flat pricing for each improvement, and a documented photo record of conditions found; no recommendations without numbers, and no pressure to commit. Call (562) 526-6978 to schedule - we answer live, 24/7.
