Insulation Company in Irvine, CA
Blown in insulation is the most common retrofit we handle in Irvine, and for good reason: much of the city’s housing stock was built in the 1970s and 80s with R-11 or R-19 fiberglass batts that have since compressed, settled, or been pushed aside by decades of attic traffic. Irvine’s hot Santa Ana wind events and warm inland summers push attic temperatures high enough that under-insulated tract homes in neighborhoods like Woodbridge and University Park lose conditioned air at a rate homeowners feel in their August utility bills. Stratford Insulation has served Irvine since 2015, matching the right material to each home rather than pushing one product.

Why Irvine Homes Are Different
Irvine is a master-planned city built largely by the Irvine Company, which means the housing stock follows a pattern you do not see in older, organically grown Orange County cities. The original 1970s and 80s villages – Woodbridge, University Park, Turtle Rock – went up fast with standard wood-frame stucco construction and the minimum insulation code of their era. Those original R-11 and R-19 attic batts are now forty to fifty years old, and in many homes they have compressed to a fraction of their original thickness. Meanwhile, the 2000s-era subdivisions and dense condo and townhome pods near the Spectrum and Great Park present a different challenge: complex low-pitch rooflines and attached garages that make attic access tight and air-sealing detail work harder than it looks from the street.
The other thing that makes Irvine jobs different is regulatory. Many of the city’s neighborhoods carry HOA and Irvine Company architectural requirements that govern what can and cannot change on the exterior, and Title 24 energy code compliance matters when you pull a permit for a major insulation upgrade. Technicians who work Irvine regularly know to check for those constraints before recommending a venting or roof-deck approach. Coastal dampness from the marine layer also means wall and crawlspace moisture control is part of the conversation here, even though the city’s bigger comfort problem is attic heat gain during Santa Ana conditions. In Woodbridge specifically, we regularly see original fiberglass batts under a radiant-barrier-less roof deck where topping up to current Title 24 R-values is one of the most straightforward efficiency upgrades a homeowner can make.
Our Main Irvine Services
Two services account for most of the calls we get from Irvine homeowners: attic insulation retrofits for aging planned-community tract homes, and spray foam for newer builds and the dense multifamily stock near the Spectrum and Great Park where air-sealing and space constraints push toward foam.
Attic Insulation in Irvine
Attic work in Irvine usually means one of two things: topping up compressed batts in a 1970s or 80s village home, or air-sealing and reinsulating a 2000s-era subdivision house where the original install was thin and the roofline makes access awkward. Many Woodbridge and University Park homes still sit at R-11 or R-19 in the attic, well below what Title 24 expects for new work today. We inspect what is up there, measure settled depth, check for rodent damage and bypass gaps, and recommend either a blown-in top-up or a full removal and rebuild depending on condition. Read the full breakdown on our Attic Insulation in Irvine page.
Spray Foam Insulation in Irvine
Spray foam earns its keep in Irvine’s newer dense construction, where attached garages, shared walls, and tight attic spaces leave little room for bulky batts. We install both open-cell and closed-cell foam using Icynene and Demilec product lines, which lets us match the foam to the specific moisture, air-sealing, and R-value requirement of each project rather than forcing one system on every house. In townhome and condo pods near the Spectrum, closed-cell foam on the roof deck is often the cleanest path to both code compliance and real thermal performance. Details, costs, and project photos are on the Spray Foam Insulation in Irvine page.

Blown In Insulation in Irvine
Blown in insulation in Irvine is the retrofit that pays for itself fastest in the city’s 1970s and 80s tract homes. Original R-11 and R-19 fiberglass batts in Woodbridge, University Park, and Turtle Rock attics have settled and compressed over four to five decades, and when a Santa Ana heat event pushes attic temperatures past 130 degrees, that thin layer is not doing much to keep conditioned air in the living space below. We blow loose fill over the existing material to bring those attics up to current Title 24 R-values in a single visit, or remove and replace entirely when the original batts are rodent-damaged, dusty, or full of bypass gaps. See our full Blown In Insulation service page for material options and project examples.
Cellulose Insulation
Signs you need it
You need cellulose if your Irvine attic batts have compressed to less than half their original depth, or if you want a recycled-content material that also slows air movement better than fiberglass.
What it costs in Irvine
Blown cellulose for a typical Irvine attic runs about $1.50 to $2.60 per square foot, with GreenFiber recycled-content stock available for eco-conscious homeowners.
How we do it
We prep the attic by air-sealing bypass gaps and confirming ventilation, then blow GreenFiber cellulose to the specified depth and R-value, checking bag count and depth markers as we go.
Blown In Attic Insulation
Signs you need it
You need a blown-in attic top-up if your Irvine home is original to the 1970s or 80s villages and the attic still carries R-11 or R-19 batts, or if upstairs rooms run noticeably hotter than downstairs during Santa Ana conditions.
What it costs in Irvine
Blown in attic insulation in Irvine typically ranges from $1,400 to $3,000 for a 1,200 to 1,800 square foot attic, depending on existing depth and whether rodent remediation or air-sealing is needed first.
How we do it
We cover the access with plastic, run a hose from the truck to the attic, and blow loose fill to the target depth, building a level blanket that restores thermal performance without disturbing the ceiling below.
Blown In Cellulose Insulation
Signs you need it
You need blown in cellulose when you want a dense, fire-retardant-treated, recycled-content fill that fills wall cavities and odd attic corners better than batts ever will.
What it costs in Irvine
Blown in cellulose for an Irvine attic or wall cavity runs about $1.50 to $2.60 per square foot, with the material cost offset by its higher installed R-value per inch and recycled content.
How we do it
We dense-pack cellulose into enclosed cavities or loose-blow it across open attic floors, using depth markers and bag counts to hit the R-value the project specifies.
Blown In Fiberglass Insulation
Signs you need it
You need blown in fiberglass if you want a lighter, moisture-resistant loose fill that will not settle as much as older fiberglass products and works well over existing batts in an Irvine attic.
What it costs in Irvine
Blown fiberglass for an Irvine attic runs about $1.20 to $2.30 per square foot, with brand availability from Owens Corning and Johns Manville depending on the R-value target.
How we do it
We blow the fiberglass loose fill to the required depth, using a machine calibrated for the material, and level the blanket so there are no thin spots over the living space.

Yes, when installed to the required depth for the R-value zone. We install to current Title 24 R-values on every Irvine retrofit, and we record bag count and depth so the compliance documentation is straightforward.
