Blown-In Insulation in Irvine - Same-Day Service, Done Right the First Time

Fast, Reliable Blown-In Insulation Across Irvine

Blown-in insulation in Irvine typically costs $1.80 to $3.20 per square foot of attic floor, with most complete attic jobs running $2,400 to $5,800 depending on village era and whether air sealing is needed first. Our crews serve Irvine from our Los Angeles dispatch office, and we can usually inspect your attic within 24 to 48 hours of your call. We know the difference between a 1978 Turtle Rock stucco tract home with original R-11 batts and a 2019 Portola Springs build with Title 24-compliant loose fill, and that knowledge changes what we blow, how deep, and in what sequence.

Our Blown-In Insulation Services in Irvine

Blown-In Fiberglass

We blow Owens Corning and Johns Manville loose-fill fiberglass in Irvine attics where the existing substrate is clean and the primary goal is restoring R-value to current Title 24 levels. In Turtle Rock and University Park, we regularly find original batts compacted to 3 to 4 inches; our Blown-In Insulation team pre-sets the blower to achieve R-38 at 14 to 16 inches depth, matching the village’s standard rafter bay width. The material doesn’t settle like cellulose, which matters in Irvine’s wide daily temperature swings where thermal cycling is constant from June through October.

Blown-In Cellulose

GreenFiber cellulose works well in Irvine homes where we’re dense-packing wall cavities or topping attics with existing fiberglass that we’re not removing. We use it less often in open attic floors because Irvine’s Santa Ana wind season can drive dust through any remaining bypass; cellulose’s finer particles migrate more readily than fiberglass if air sealing is skipped. When we do use it, we seal first. Always.

Dense-Pack Wall Insulation

Irvine’s 1970s and 1980s stucco tract homes were framed with empty wall cavities or thin R-11 batts that barely reached the top plates. Dense-packing fills those cavities with blown cellulose or fiberglass at 3.5 pounds per cubic foot, creating an air-impermeable barrier that stops the Santa Ana-driven infiltration we see pushing through outlet plates and baseboards in Woodbridge and University Park. We dense-packed the wall cavities near the original sliding glass door in that 1978 Turtle Rock home, cutting the air infiltration that had been pushing dust and heat through the outlet plates. The blower-door test dropped 1,400 CFM50 from that step alone.

Blown-In Top-Up

A top-up is not always the right move, but in Irvine’s newer villages, it often is. Portola Springs and Stonegate homes built to 2016 Title 24 standards usually have adequate depth but suffer from failed attic hatch gaskets and unsealed can lights that undermine the existing R-value. We air-seal first, then blow a targeted top-up to restore depth where the original material has shifted or compressed. In older villages, a top-up over unsealed, settled batts is a waste of money; we’ll tell you if that’s your situation and show you the blower-door reading that proves it.

Trusted Brands We Service in Irvine

We stock Owens Corning, Johns Manville, and Knauf blown-in products for Irvine jobs, with no proprietary lock-in that forces a material you don’t need. Our truck inventory matches the most common Irvine village configurations: Owens Corning AttiCat for standard R-38 attic restorations, Johns Manville Climate Pro for dense-pack wall work, Knauf EcoFill for homeowners who prefer unfaced fiberglass in humid coastal-adjacent conditions. Because we know the template your Irvine Company builder used, we order material by the village, not by the guess. That keeps turnaround tight and waste minimal.

Common Blown-In Insulation Problems We See in Irvine Homes

• Builder-grade attic hatch gaskets in Portola Springs and Stonegate fail within the first warranty year. Conditioned air escapes into the attic through a gap you can’t see from below, and your blown-in R-value becomes irrelevant because the heat is leaving through the hatch frame. We replace with a gasketed, insulated hatch and seal the frame to the drywall before touching the insulation.
• Original compacted fiberglass batts in 1970s Woodbridge and University Park attics have settled below R-11. The thermal bridging at the top plates means blown-in top-ups alone can’t fix the problem; air sealing of top plates, wire penetrations, and can-light housings has to happen first. We won’t blow over an unsealed attic floor. Haven Standard Clause 1: written scope, written price, written warranty before anyone lifts a tool.
• Tile-roof construction in Great Park Neighborhoods traps radiant heat in the attic. Without a radiant barrier, blown-in insulation slows conductive heat but can’t stop the 90 to 95°F afternoon load from radiating through the ceiling drywall. We assess whether your tile-roof attic needs a radiant barrier plus blown-in, or whether air sealing and depth correction are sufficient.
• Santa Ana wind events drive hot, dry air through poorly sealed attic bypasses and wall penetrations. Fall wind seasons in Irvine compound energy loss in homes that were never tightly air-sealed to begin with. We find these bypasses with a blower-door test and smoke pencil, seal them with foam and caulk, then blow insulation over a surface that actually holds air.
