Insulation Company in Irvine, CA
Blown in insulation is the most common retrofit we install in Irvine, and for good reason. The city’s two-story tract homes, built mostly between the 1970s and 2010s, rarely left the factory with enough attic coverage for an inland climate that sees high 90s and low 100s through summer. Loose fill lets us add depth over existing batts and fill the odd cavities around recessed lights, duct chases, and garage ceilings without tearing anything apart. If your upstairs runs 10 degrees hotter than downstairs, the attic is almost always the problem. Call Fontana Insulation at (866) 271-1602 and we’ll tell you exactly what’s up there and what it needs.
Why Irvine Homes Are Different
Irvine is not a typical Southern California city. It’s a master-planned network of villages, each with its own HOA rulebook, architectural committee, and building era. That changes insulation work in ways you don’t see in older, unplanned cities. In Woodbridge and Northwood, original R-13 fiberglass batts from the 1970s and 1980s are often compressed to half their rated depth, missing entirely over the garage, or degraded by rodent activity. In Great Park and Spectrum-area homes built after 2010, the envelope is tighter, but recessed-light housings and duct runs in unconditioned attics still leak conditioned air at predictable points. Santa Ana winds pressurize attics through soffit vents and push hot, dry air across whatever insulation is there. The homes are stucco, wood-frame, and tile-roofed, which means the attic floor is the thermal boundary that matters most. Cooling dominates the energy bill here, so we’re always working toward radiant heat control and air-sealing, not just adding R-value for winter.
Our Main Irvine Services
Most Irvine homeowners call us first about two things: an attic that’s turning the upstairs into an oven, or air leaks that standard insulation never solved. Both are covered below.
Attic Insulation in Irvine
Attic work in Irvine usually means correcting what was done decades ago or never done right. In Woodbridge and Northwood, we routinely find original batts that settled to R-8 or less, soffit vents buried under years of blown debris, and garage ceilings with no insulation at all. The fix starts with a visual inspection, then a recommendation that matches your home’s construction era and HOA constraints. Some jobs are a simple top-off with blown fiberglass over existing batts. Others need old material removed first. We carry eight brands so the recommendation comes from the attic, not our inventory. See Attic Insulation in Irvine for the full breakdown.
Spray Foam Insulation in Irvine
Spray foam earns its cost in Irvine when air-sealing matters as much as thermal resistance. Two-story tract homes with vaulted ceilings, bonus rooms over garages, or ductwork running through unconditioned attics all benefit from the air barrier that open-cell or closed-cell foam creates. We’re authorized installers for Icynene and Demilec, two of the most tested foam systems in North America. The decision between open-cell and closed-cell depends on your roof assembly, budget, and whether the attic is vented or unvented.

Blown In Insulation in Irvine
Blown in insulation, also called loose fill, is the fastest way to bring an Irvine attic up to current code depth without removing what’s already there. We blow fiberglass or cellulose over existing batts in a couple of hours, and the material settles into the gaps and odd corners that batt insulation leaves open. In Irvine’s original Woodbridge and Northwood tracts, that means filling the voids over garages and around recessed-light cans where heat pours into the house. Our crews install Blown In Insulation daily across Irvine, and most jobs are done before noon.
Cellulose Insulation
Signs you need it
Your attic has old, settled batts with gaps, or you want a recycled-content material that fills cavities more completely than fiberglass.
What it costs in Irvine
Blown cellulose for an Irvine attic typically runs $1.50 to $3.00 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor penetrations, set depth markers, then blow GreenFiber cellulose to the target R-value with a calibrated machine.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms won’t hold temperature, or your attic has less than 10 inches of existing insulation across most of the floor.
What it costs in Irvine
Blown in attic insulation in Irvine runs $1,800 to $3,800 for a typical 1,200 to 1,800 square foot attic space.
How we do it
We inspect the existing material, seal the major air leaks, and blow fiberglass or cellulose to an even depth across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
You want a cost-effective top-off over existing batts, or your attic is irregularly shaped with cavities batts can’t fill.
What it costs in Irvine
Blown fiberglass in an Irvine attic typically runs $1,400 to $3,200 depending on square footage and target depth.
How we do it
We set depth gauges around the attic, then blow Knauf or CertainTeed fiberglass to a consistent, code-meeting depth.
Loose Fill Insulation
Signs you need it
You have an older Irvine home with original batts that are compressed, patchy, or missing over the garage and around the perimeter.
What it costs in Irvine
Loose fill as a retrofit over existing batts generally runs $1,200 to $2,800 for a typical Irvine tract home attic.
How we do it
We blow loose fill material into the attic under pressure so it flows into corners, rafter bays, and around framing that batts miss.
What Blown In Insulation Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Blown cellulose per sq ft installed | $1.50 – $3.00 |
| Blown fiberglass per sq ft installed | $1.00 – $2.50 |
| Typical 1,200 – 1,800 sq ft attic retrofit | $1,800 – $3,800 |
Prices in Irvine shift with attic access, existing material removal, and how much air-sealing the attic needs before we blow. A home with vaulted ceilings or a low-pitch roof over the garage costs more to insulate correctly than a simple, open attic floor.
Is blown in insulation worth it in Irvine?
Yes. Irvine’s inland summers push attic temperatures past 140 degrees, and blown in insulation is the most cost-effective way to cut heat transfer into living space. Most homeowners notice the difference within the first week of a summer month. Call (866) 271-1602 for an attic assessment and exact quote.
How long does blown in insulation last in Irvine?
Fiberglass loose fill lasts 25 to 40 years if it stays dry, and cellulose lasts 20 to 30 years. In Irvine, the bigger issue is settlement and compression, not material breakdown. We can recheck depth anytime. Call (866) 271-1602 to schedule an attic check.
Brands We Service in Irvine
Fontana Insulation carries Knauf and CertainTeed fiberglass, Rockwool mineral wool, and Icynene spray foam among our eight stocked brands. Parts and material for every job come from local supply, so we’re never waiting on a shipment to start. See our brands for the full lineup.

— Holly Mercer"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
