Insulation Company in Irvine, CA
Blown in insulation is the most common call we get from Irvine homeowners, and the reason is simple: most of this city’s housing stock was built between 1970 and 2000, when attic insulation was an afterthought. Original fiberglass batts in Woodbridge, Deerfield, and Westpark have settled, compressed, or vanished entirely over recessed light fixtures, and the hot, dry Santa Ana winds push attic temperatures past 150°F in summer. That heat bleeds through unsealed attic penetrations and into living space. North Tustin Insulation has served Irvine since 2011, matching the right material, Owens Corning fiberglass, GreenFiber cellulose, Demilec spray foam, to each home rather than pushing a single product. Call (877) 265-5712 for a straight answer on what your attic actually needs.
Why Irvine Homes Are Different
Irvine is a master-planned city where almost everything was built after 1970. That changes the insulation conversation compared to older Orange County cities. You are not dealing with no insulation, you are dealing with builder-grade insulation that met minimum code in 1982 and has been underperforming ever since. Many of the 1970s and 80s tract homes in neighborhoods like El Camino Real and the Ranch still have R-11 to R-13 fiberglass batts in 2×4 wall cavities and maybe R-19 in the attic, which was the bare minimum when they were framed. The newer high-density townhomes and condos in ZIPs 92618 and 92620 often have tight framing, trusses, and shallow attic space, but the insulation was frequently value-engineered down to code minimum during construction. Add Irvine’s strict HOA and architectural review rules, and you get a city where attic-to-interior encapsulation work needs approval and careful detailing. The summer sun on south- and west-facing stucco walls makes attic ventilation and air sealing far more important than most homeowners realize. Insulation here is primarily about cooling efficiency and soundproofing, not winter heating, but that does not make it optional. It makes it a comfort and utility-bill issue every August.
Our Main Irvine Services
Most Irvine homeowners reach out to us for one of two reasons: an attic that is roasting the upstairs rooms, or a new construction or remodel situation where spray foam is the smartest air-sealing move. Here is how each one works in this city specifically.
Attic Insulation in Irvine
Irvine’s 1980s and 90s Mediterranean-style stucco homes look great from the street, but their attics are often under-insulated by today’s standards and packed with unsealed penetrations: recessed lights, bathroom fan vents, and plumbing chases. When the Santa Ana winds blow hot, dry air across the roof, that heat loads into the attic and radiates down into bedrooms. We inspect what is up there, measure settled depth, identify compressed or missing sections, and recommend either topping off with blown-in material or removing and replacing degraded batts. Many homes in ZIP 92604 and 92614 still have original insulation from construction day. Read more on our dedicated Attic Insulation in Irvine page.
Spray Foam Insulation in Irvine
The newer Irvine developments, especially the townhome and condo clusters in 92618 and 92620, tend to have limited attic space and tight framing. Open-cell spray foam is often the best fit here because it air-seals and insulates in one application without needing a deep attic cavity. We carry both Icynene and Demilec systems, so we can match open-cell or closed-cell foam to the specific job, whether that is a cathedral ceiling in a remodel or a knee wall in a third-story bonus room. HOA approval is often part of the process, and we can advise on what documentation helps. Details are on our Spray Foam Insulation in Irvine page.

Blown In Insulation in Irvine
Blown in insulation is the workhorse solution for Irvine’s 1970s through 1990s tract homes, especially where the original batts have settled or never filled the attic properly in the first place. Loose-fill material pours into the irregular spaces around trusses, electrical boxes, and ductwork, creating a continuous thermal layer that batts simply cannot match. In a city where attic temperatures routinely exceed 150°F in summer, that continuous coverage is what keeps upstairs rooms livable without running the AC around the clock. North Tustin Insulation has served Irvine since 2011, and we install blown-in cellulose and blown-in fiberglass using calibrated machines that achieve the exact R-value your attic needs. For more detail on how blown-in works across different home types, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has old, compressed fiberglass batts that no longer fill the joist bays, and you can see the drywall or joist tops in multiple places.
What it costs in Irvine
Blown-in cellulose in Irvine typically ranges from $1.15 to $2.10 per square foot installed, depending on target R-value and access.
How we do it
We air-seal the attic penetrations first, then blow GreenFiber recycled cellulose to the specified depth using an insulation blower and calibration checks throughout.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms are consistently 8 to 12 degrees warmer than downstairs on summer afternoons, and attic inspection shows less than 5 inches of settled material.
What it costs in Irvine
A full blown-in attic insulation job in Irvine typically spans $995 to $2,700 for a standard 1,000 to 1,500 square foot attic.
How we do it
Our crew removes or pushes aside any old, degraded material, seals the ceiling penetrations, and blows loose-fill insulation to the code-required depth for your climate zone.
Blown In Cellulose Insulation
Signs you need it
Your energy bills climb every August, and pulling back a section of attic insulation reveals gaps, voids, or material that crumbles to the touch.
What it costs in Irvine
Blown-in cellulose for Irvine homes ranges from $1.15 to $2.10 per square foot, with attic-specific jobs often landing between $995 and $2,700 after sealing work.
How we do it
We use GreenFiber cellulose, a recycled-paper product with borate treatment, and blow it to a consistent depth across the entire attic floor so there are no thin spots.
Blown In Fiberglass Insulation
Signs you need it
You want the most cost-effective loose-fill option, and your attic has good access with no history of roof leaks or persistent moisture problems.
What it costs in Irvine
Blown-in fiberglass in Irvine typically runs $0.90 to $1.75 per square foot installed, depending on the R-value your attic currently needs.
How we do it
We blow Owens Corning fiberglass at the manufacturer’s specified density, checking coverage with depth markers and adding extra attention around the attic hatch and eaves.
Loose Fill Insulation
Signs you need it
Your attic floor is cluttered with trusses, cross-bracing, and vent pipes that make batts impractical, and you want continuous thermal coverage without gaps.
What it costs in Irvine
Loose fill insulation in Irvine generally falls between $0.90 and $2.10 per square foot, with price driven by material choice and attic prep work.
How we do it
We prep the attic, seal air leaks, and use a loose-fill blower to distribute material evenly from the eaves to the attic access point, verifying depth as we go.
What Blown In Insulation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Blown-in fiberglass (attic) | $0.90 – $1.75 per sq ft installed |
| Blown-in cellulose (attic) | $1.15 – $2.10 per sq ft installed |
| Full attic blow-in job (1,000 – 1,500 sq ft) | $995 – $2,700 |
Is blown in insulation worth it in Irvine’s climate?
Yes. Irvine’s summer attic heat is the main energy drain, and blown-in material creates a continuous thermal barrier that batts with gaps and seams cannot match. Most homeowners see a noticeable upstairs temperature difference within a day of installation, and utility savings follow.
Can you do blown in insulation same day in Irvine?
In most cases, yes. A standard attic in a 1970s-80s Irvine tract home takes one day from prep to final depth check. Larger homes or jobs requiring old insulation removal may take a second day. Call (877) 265-5712 for a time estimate on your specific attic.

Most materials are stocked locally, not special-ordered, so we can start quickly after estimate approval. See our brands for the full lineup.

For interior work like attic insulation, usually not. For anything visible from the street or exterior, like spray foam in a garage ceiling or attic access changes, many Irvine HOAs want a quick architectural review. We can provide the material specs and scope description your HOA typically asks for.
No. The mildness of Irvine’s winter is not the issue; the intense summer sun and 150°F attic temperatures are. Insulation here is a cooling and soundproofing investment first. Well-insulated Irvine attics keep upstairs rooms comfortable and reduce AC runtime from June through October, which is most of the year.

— Nathan Padgett"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
