Insulation Company in Irvine, CA
Blown in insulation is the most common retrofit we handle in Irvine, and for good reason: most of the city’s tract-built homes from the 1970s through the 2000s have attic insulation that’s settled well below current code recommendations. Irvine’s master-planned villages mean homes in the same community often share identical attic configurations, so when we diagnose one Woodbridge or Northwood home, we usually know what the whole street is dealing with. If your upper floor runs five to eight degrees warmer than downstairs every summer afternoon, call Maple Insulation Co at (855) 341-6045 and we’ll tell you what’s actually in your attic.
Why Irvine Homes Are Different
Irvine’s housing stock is unusually uniform for a city of 300,000 people. The Irvine Company built most of the older villages between the mid-1970s and early 2000s, and the newer Great Park and Orchard Hills communities followed the same master-planned formula: wood-frame construction, stucco cladding, low-pitch concrete tile roofs, and attached garages. That last detail matters more than most homeowners realize. Attics here tend to be tight and low-clearance, and the access hatch is often tucked into a hallway ceiling or closet, which means blown in insulation work happens in spaces where a technician may be working on their knees or reaching through a scuttle hole smaller than a sheet of plywood.
The climate shapes the work too. Irvine rarely freezes, and winter heating loads are modest compared to inland Orange County cities. What drives insulation demand here is summer: attic temperatures in July and August routinely exceed 140 degrees, especially during Santa Ana events when the marine layer clears out and the sun beats directly on those tile roofs. Insulation that performed fine in a milder climate becomes the difference between a second floor that holds 74 degrees and one that makes your air conditioner run from noon to midnight. Many older Irvine homes still carry the original builder-grade fiberglass batts, which were often installed to 1980s minimums and have since compressed or been pushed aside during decades of contractor traffic.
Our Main Irvine Services
Most Irvine homeowners call us about one of two problems: an attic that’s bleeding conditioned air into a 140-degree space, or a home that needs the air-sealing and high-R-value performance only spray foam can deliver in certain assemblies. Here’s how each works in Irvine.
Attic Insulation in Irvine
Attic work in Irvine almost always starts with an inspection of what’s already up there, because the village your home was built in tells us a lot about what we’ll find. University Park and early Woodbridge homes typically have thin fiberglass batts laid between ceiling joists, while 1990s Westpark and Northwood builds often have blown in fiberglass that’s settled several inches. Tight clearances and low-pitch roofs make access slow, but we handle it daily. Read more about Attic Insulation in Irvine.
Spray Foam Insulation in Irvine
Spray foam makes sense in Irvine when air sealing matters as much as R-value, which is often the case in homes where attic ductwork runs through unconditioned space. We spray both open-cell and closed-cell products from Icynene and Demilec, and the choice between them depends on your roof configuration and moisture profile. HOA rules in some villages restrict visible changes, but spray foam applied inside the attic doesn’t alter exterior appearance. See Spray Foam Insulation in Irvine for details.

Blown In Insulation in Irvine
Blown in insulation is the workhorse retrofit for Irvine’s older tract homes, because it’s the fastest way to bring an under-insulated attic up to modern performance without tearing out ceilings or disrupting the living space below. Homes in Northwood, Woodbridge, and University Park were built when R-19 attic insulation was considered adequate; today we routinely bring those attics up to R-38 or higher, and the difference in upstairs comfort is immediate. Blown In Insulation lets us work through narrow access points and fill irregular cavities that batts can’t reach, which matters in a city where many attics are barely tall enough to crawl through.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to the point where ceiling joists are visible, or your upstairs runs noticeably warmer than downstairs from mid-afternoon onward.
What it costs in Irvine
Cellulose attic insulation in Irvine typically runs $1.20 to $2.30 per square foot installed, including prep and cleanup.
How we do it
We remove debris and old damaged material as needed, air-seal penetrations where feasible, then blow GreenFiber cellulose to the target depth using a truck-mounted hopper outside the home.
Blown In Attic Insulation
Signs you need it
Your attic has bare spots, thin coverage, or you can see the original fiberglass batts compressed flat between joists.
What it costs in Irvine
Blown in attic insulation in Irvine generally falls between $1,500 and $3,200 for a typical 1,500 to 2,200 square foot single-family home, depending on existing depth and access.
How we do it
We set up containment at the access point, run a hose into the attic, and blow material evenly across the attic floor until it reaches a consistent depth matching the target R-value.
Blown In Cellulose Insulation
Signs you need it
You want a dense-pack or loose-fill option with higher recycled content than fiberglass, or existing fiberglass has been contaminated by rodent activity and needs removal.
What it costs in Irvine
Blown in cellulose in Irvine typically runs $1.20 to $2.30 per square foot for attic applications, with dense-pack wall retrofits priced by cavity volume rather than floor area.
How we do it
We run GreenFiber cellulose through our blower at the calibrated density for your application, whether that’s loose-fill across an attic floor or dense-packed into enclosed wall cavities.
Loose Fill Insulation
Signs you need it
You’re topping up an attic that already has some insulation but doesn’t meet current R-value targets for Irvine’s climate zone.
What it costs in Irvine
Loose fill insulation to top up an existing attic in Irvine typically costs $0.90 to $1.80 per square foot when no removal is required.
How we do it
We blow loose-fill material over the existing layer after checking for moisture problems, recessed light clearances, and ventilation blockages.
What Blown In Insulation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Blown in fiberglass attic insulation | $0.90 – $1.80 per sq ft |
| Blown in cellulose attic insulation | $1.20 – $2.30 per sq ft |
| Full attic blow-in for a 1,500 – 2,200 sq ft home | $1,500 – $3,200 |
Can you blow in insulation over existing material in Irvine attics?
Yes, in most Irvine attics we can blow new material directly over existing fiberglass or cellulose as long as there’s no moisture damage, rodent contamination, or mold. We check those conditions during the inspection before recommending a top-up versus a full removal and re-blow.
Is blown in insulation worth it in Irvine’s mild climate?
Yes, because Irvine’s problem is attic heat gain, not winter cold. A properly insulated attic keeps 140-degree air out of your living space in summer, which cuts air conditioning runtime and evens out upstairs temperatures. Most homeowners notice the difference within the first hot week.
Brands We Service in Irvine

Because we stock multiple brands and materials, we’re not tied to selling one product line.

In Irvine, price is most affected by attic access and clearance. Homes in older villages like Woodbridge and University Park often have scuttle holes in closets and attics with less than four feet of headroom, which slows the work and adds labor. You’ll get an upfront price before any material goes in, no surprises after the fact.

What Irvine Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Ruben Guzman"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Kevin Chen"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Eric Fletcher
