Fast, Reliable Spray Foam Insulation Across Irvine
Spray foam insulation in Irvine typically costs $2.50 to $6.50 per square foot installed, with most attic projects landing between $3,500 and $9,000 depending on foam type and cavity depth. We reach neighborhoods across Woodbridge, Northwood, University Park, and the Great Park villages within a day or two of your call. Call (866) 605-6949 for a free estimate, and we’ll send a technician who knows Irvine’s housing stock, not someone reading off a generic checklist.
Irvine homes were built fast, in big village master plans, mostly between the 1970s and early 2000s. That means tight attic cavities, low-pitch Mediterranean tile roofs, and original insulation that was thin when it went in and has only settled since. If your upstairs rooms bake every afternoon and chill every morning, the problem usually isn’t your HVAC. It’s the thermal boundary around it. Spray Foam Insulation closes those gaps when it’s matched to the right cavity and the right foam chemistry. That’s the work we do every day.
Why Hollywood Insulation Co Is Irvine’s Preferred Spray Foam Insulation Company
We’re a dedicated insulation contractor, which means every tech who shows up in Irvine spends their whole week thinking about air leakage, R-value, and vapor drive. Not bathrooms, not kitchens, not whatever else came in that morning. Irvine homeowners call us because the crew actually understands what marine-layer salt air does to attic hardware and foil-faced ductwork, and they plan the job around it.
Our Spray Foam Insulation team services the 92617, 92618, 92619, and 92620 ZIP codes every week. We know that a townhome off Barranca Parkway in Woodbridge has a very different attic than a detached 1990s tract home in Westpark, and we treat them differently. We carry both Icynene and Demilec spray foam systems, open-cell and closed-cell, so we’re not forcing one product into every application. The recommendation follows the house, not the truck inventory.
Noel Camacho, who leads our insulation work, has spent years diagnosing exactly the failure patterns Irvine’s housing stock produces: crushed batts around recessed lights, rusted fasteners, and under-vented tile-roof attics that trap moisture against everything inside them. That’s the local knowledge you can’t get from a general contractor doing insulation on the side.
Spray Foam Attic Insulation in Irvine
Spray Foam Attic Insulation in Irvine is the single highest-impact upgrade for the majority of 1970s-to-2000s tract homes and townhomes we inspect, because those attics were built with minimal R-value and almost no air-sealing. A typical attic spray foam job in Irvine runs $3,500 to $8,500 for open-cell foam applied to the roof deck, or $6,000 to $12,000 for closed-cell when we’re also addressing moisture control. The cost swings on roof pitch, attic access, and how much prep the existing penetrations require.
The prep is the make-or-break step here. Irvine attics are full of recessed can lights, HVAC chases, and framing penetrations that were never sealed. Foam over those gaps without sealing the metal-to-drywall transitions first, and you’ve just insulated a leak. Our crews air-seal the penetrations, then apply the foam so it actually performs to its rated R-value.
Open-Cell Foam for Tile-Roof Attics
Open-cell Icynene works well in Irvine attics where the roofline is low-pitch Mediterranean tile and access is tight. It expands into irregular cavities, seals air movement, and won’t trap moisture the way closed-cell can when applied against already-rusting metal surfaces. We use it on the majority of roof-deck applications in Woodbridge and Northwood townhomes.
Closed-Cell for Attics With Moisture Exposure
Closed-cell Demilec is the choice when the attic has condensation-driven rust on fasteners, duct boots, or radiant-barrier foil facing. It adds structural rigidity and acts as a vapor barrier. We’re selective about where we recommend it, because sealing a wet attic with the wrong foam creates bigger problems than it solves.
Spray Foam Wall Insulation in Irvine
Spray Foam Wall Insulation in Irvine is most often the right call for exterior wall retrofits on 1970s and 1980s builds where the original batt has sagged inside second-story bedrooms and west-facing rooms. A wall cavity injection job in Irvine typically runs $1,800 to $4,500 per floor, depending on access and whether we’re working from the exterior or through drywall. It’s a targeted fix for specific hot and cold spots, not something we recommend on every home.
South- and west-facing walls in Irvine’s tract homes absorb enormous afternoon solar load. Original fiberglass batts don’t stop radiant heat, and once they sag, a two-inch gap opens at the top of the stud bay. Foam fills the entire cavity, including the gap the batt left behind, and it air-seals the wall in a way batts physically cannot.
Shared-Wall Townhome Applications
In attached Woodbridge and University Park townhomes, we often inject open-cell foam into party walls to stop air movement and sound transfer between units. The foam seals the common wall cavity so cool-morning drafts stop pulling through from the neighbor’s unconditioned attic. It’s a specialized application most Irvine homeowners don’t know exists until the comfort problem won’t go away.
Rim Joist Sealing at the Foundation Line
Rim joist spray foam seals the transition between foundation and framed wall, which is a major air leakage point in 1980s Irvine slab-on-grade construction. We apply closed-cell Demilec at the rim, which stops the stack effect that pulls hot attic air down through walls and cold air up through the bottom plate. It’s a small job, usually under $1,200, but it pays for itself in a single cooling season for many Irvine homes.
Trusted Brands We Service in Irvine
We install Icynene spray foam systems, Demilec spray foam systems, and when the job calls for a different method, Owens Corning batts and GreenFiber cellulose. Carrying multiple brands means we stock the right material for the specific Irvine application, not the one material we happen to have a rebate on. That matters in a town where the attic conditions range from dry and hot in Great Park condos to salt-air damp in Woodbridge townhomes. We keep local material stock for Irvine projects so we’re not waiting on a distributor when you need the job done.
Common Spray Foam Insulation Problems We See in Irvine Homes
- Corroded garage-door hardware and opener chains from marine-layer salt air. The same morning overcast that keeps Irvine mild also deposits salt on metal surfaces, and garages near the coast see springs and hinges fail years before inland Orange County homes. If you’re foaming a garage-adjacent attic without addressing the rusting hardware, you’re sealing moisture against already-failing metal.
- Crushed or missing batt around recessed can lights and HVAC chases. Original 1980s builds in Northwood and University Park almost always show compressed fiberglass around penetrations, because the builders never air-sealed before insulating. Foam applied over these hidden gaps leaves seasonal draft channels that defeat the entire job.
- Under-vented low-pitch tile roofs trapping condensation. Mediterranean tile roofs common across Irvine village tracts leave little room for proper soffit-to-ridge venting. Foam installed without planning for ventilation traps moisture that attacks fasteners, track hardware, and foil-faced radiant barrier sheathing.
- Foil-facing corrosion on radiant-barrier sheathing and metal duct boots. The same coastal moisture that rusts garage hardware oxidizes foil surfaces in attics. We inspect all foil-faced materials before foaming, because once closed-cell foam goes over degraded foil, you’ve locked in a corrosion problem.
Pricing for Spray Foam Insulation in Irvine, CA
Here’s what Irvine homeowners should expect. Open-cell attic roof-deck foam runs $2.50 to $4.00 per square foot. Closed-cell runs $3.50 to $6.50 per square foot.

FAQs About Spray Foam Insulation in Irvine
Yes. Irvine’s marine-layer mornings deposit salt on exposed metal surfaces, and over years this corrodes garage-door springs, opener chains, hinges, and track fasteners. Before we apply foam in any attic with these conditions, we inspect the hardware and foil-faced materials, and we recommend galvanized or stainless replacements where the corrosion is already active. Foam sealing an unaddressed garage can trap moisture against rusting metal and accelerate failure. Call (866) 605-6949 and we’ll look at what’s actually rusted before any foam goes up.
Because virtually every 1970s-to-1990s Irvine tract home was built without air-sealing at penetrations, and the original batt insulation is now crushed or missing around those same points. If you don’t seal the can light housings and HVAC chase transitions before foaming, you’re locking in a permanent draft channel that lets Irvine’s warm afternoon air into the living space and pulls cooled air out through the attic. It’s the number one reason foam jobs in Irvine underperform. We seal first, then foam. It’s not optional here.
The low-pitch Mediterranean tile roofs on Irvine’s village tracts leave very little clearance for attic access and almost no room for conventional soffit-to-ridge ventilation. That restricted venting means condensation builds inside the attic, attacks fasteners and duct boots, and corrodes foil-faced radiant barrier sheathing. Foam installed without accounting for this traps the moisture permanently. Our crews inspect venting and existing corrosion before recommending open-cell or closed-cell foam, because the wrong choice in a tile-roof Irvine attic creates a rust problem you can’t see until it’s expensive.
Yes, and it’s one of the most common reasons Irvine homeowners call us. Rooms facing south and west in University Park and Great Park homes absorb intense afternoon sun, and original fiberglass batts cannot stop radiant heat transfer. Spray foam fills the wall cavity completely, including the gap where batt has sagged, and it air-seals the wall assembly so hot outside air stops moving through the stud bays. Closed-cell Demilec works especially well here because of its higher R-value per inch, which matters when you’re retrofitting a 2×4 wall. The result is a bedroom that stays within a few degrees of the hallway instead of ten degrees hotter by 4 p.m.
Yes. We cover all Irvine ZIP codes, including 92617, 92618, 92619, and 92620, which means Woodbridge, Northwood, University Park, Westpark, and the newer Great Park and Irvine Spectrum-adjacent villages. Our crews are in these neighborhoods every week, and we know the difference between a 1980s Woodbridge townhome attic and a 2015 Great Park condo’s tight truss cavity. If you’re in one of these villages, call (866) 605-6949 and we’ll tell you honestly whether spray foam is the right fix for your specific home.
