Why Hollywood Insulation Co Is Irvine’s Preferred Attic Insulation Company
We’re a dedicated Attic Insulation specialist, not a general contractor dabbling in the trade. Every technician on our Irvine jobs does one thing: diagnose thermal bypasses, air leakage, and R-value deficiencies. That focus shows up in the details. When our crew works a 1980s Woodbridge townhome, they check the recessed can lights, the HVAC chases, the shared walls, and the scuttle access before recommending a single material. Irvine is a master-planned city built almost entirely in the last ~50 years, so insulation work here is dominated by upgrading 1970s – 2000s tract homes and townhomes to Title 24-era performance. Most of these homes were built with minimal attic insulation and single-pane or early dual-pane windows, which leaves big seasonal comfort gaps across large, fast-growing village master plans.
Our Irvine customers call because their upstairs bedrooms spike in the afternoon, their downstairs halls feel drafty in the morning, or their AC runs without stopping from July through September. That’s the reality of coastal Irvine’s climate: mild, dry, with strong marine-layer morning overcast and warm inland afternoons. The real insulation drivers here aren’t severe cold, they’re solar gain in south- and west-facing rooms and cool early-morning drafts. We spec radiant barrier, attic ventilation, and air-sealing for exactly that reason.
Led by Noel Camacho, our crews know the difference between a Woodbridge townhome’s shared attic firewall and a Northwood single-family attic with a standard scuttle. That local knowledge means we show up with the right material and the right plan the first time.
Radiant Barrier in Irvine
Radiant barrier in Irvine is the single most effective upgrade for south- and west-facing rooms that spike in the afternoon, and it typically runs $800 – $2,500 depending on attic square footage and roof pitch. Here’s how it works: a low-emissivity foil layer is stapled to the underside of your roof rafters, reflecting radiant heat back out instead of letting the roof deck radiate it into the attic. Your attic can be 20 – 30 degrees cooler on an August afternoon. That’s not marketing, that’s physics on Irvine’s Mediterranean tile roofs, which absorb a lot of afternoon sun. If your AC constantly runs between 2 and 6 p.m., this is the fix.
We install radiant barrier under tile roofs in Irvine every week. The low-pitch Mediterranean tile profile makes it a careful job, working through narrow interior scuttles rather than roof hatches.
How Radiant Barrier Fits With Your Insulation
Radiant barrier doesn’t replace your insulation, it reduces the heat load your insulation has to fight. When you pair a foil layer with proper blown-in insulation and air-sealing, your attic stays dramatically cooler and your insulation works at full R-value instead of being heat-soaked.
Radiant Barrier Costs in Irvine
For a typical 1,600 – 2,200 square foot Irvine tract home, a full attic radiant barrier install runs $1,200 – $2,000. That includes the foil, the install labor, and venting adjustments. Smaller townhome attics in Woodbridge or a Great Park condo can run closer to $800 – $1,200.
Attic Cleaning Services in Irvine
Attic cleaning services in Irvine run $400 – $1,200 and involve removing old or degraded insulation, rodent debris, dust, and any construction waste before new insulation goes in. Here’s why we won’t just blow fresh insulation over a dirty Irvine attic: the original 1980s builds across this city are full of recessed can lights, HVAC chases, and shared-wall penetrations that leak air. If we skip the cleaning and air-sealing step, you’re paying for new insulation that can’t do its job. In Woodbridge, our crew pulled a crushed R-11 batt off the recessed can lights over a 1980s townhome kitchen and found the HVAC chase open to the attic, so we air-sealed every penetration before blowing GreenFiber over the existing layer. The morning marine-layer draft that used to roll down the hallway stopped, and the south-facing upstairs rooms held their afternoon temperature instead of spiking.
When an Irvine Attic Needs Cleaning
If you’ve had rodents, water intrusion, or if your insulation is more than 25 years old, you probably need cleaning before you add new material. Crushed or missing batt around recessed lights and HVAC chases is the make-or-break issue on most Irvine upgrades, and cleaning is when we find and fix those.
What Clearing an Attic in Irvine Costs
For a standard Village of Woodbridge townhome attic, cleaning and removal runs $500 – $800. Larger single-family homes in Northwood or University Park run $800 – $1,200. We include a full air-sealing pass on any job where we remove old material.

Trusted Brands We Service in Irvine
We install products from eight recognized manufacturer brands across fiberglass, mineral wool, spray foam, and cellulose categories. For Irvine attics, that usually means GreenFiber recycled cellulose blown over an air-sealed attic deck, or Owens Corning batt in tight townhome cavities. We also run Icynene open-cell spray foam and Demilec closed-cell for clients who need air sealing and R-value in the tightest Great Park condo attics. We keep local parts and materials staged for Irvine jobs, so scheduling runs fast and we’re not making homeowners wait on a warehouse run from LA.
Common Attic Insulation Problems We See in Irvine Homes
- Crushed batt around recessed can lights. Original 1980s Irvine builds used cheap R-11 or R-19 batt that gets pushed aside during remodels and then left. We find this in nearly every Woodbridge and Northwood tract home we inspect.
- Open HVAC chases venting conditioned air straight into the attic. Many original Irvine tract homes have the main HVAC chase running through the attic with no sealing. That’s the biggest thermal bypass in these houses, and it’s invisible unless you’re in the attic looking for it.
- Missing or crushed insulation under shared townhome walls. Townhome attics across Woodbridge, Westpark, and the Spectrum-adjacent villages have tight clearances and shared wall lines that block batt runs. Blown-in GreenFiber is usually the right call, so it covers and fills without compressing.
- No radiant barrier under a tile roof that soaks up afternoon sun. Irvine’s Mediterranean tile roofs are beautiful, but they radiate heat into the attic for hours after the sun moves. Without a radiant barrier, your insulation is fighting a losing battle every afternoon.

FAQs About Attic Insulation in Irvine
Yes, in most cases. Blown-in insulation works in tight attic cavities because it doesn’t require the same clearance as laying batt, and most Woodbridge and Westpark townhomes have enough room for GreenFiber blow-in even if the scuttle is tight. We’ve installed blow-in through narrow interior scuttles in nearly every Irvine village. If your attic is unusually shallow, we’ll tell you during the free estimate. Call (866) 605-6949 and we’ll check it out.
Because Irvine attics leak at specific points, not evenly. Recessed can lights, HVAC chases, and shared-wall penetrations are the thermal bypasses that let your conditioned air escape, and adding more insulation on top of those leaks doesn’t fix them. Air-sealing those penetrations before you blow in new insulation is the difference between a real improvement and a cosmetic one.
If your south- or west-facing rooms spike in the afternoon, yes. A radiant barrier under your Mediterranean tile roof reflects solar heat before it ever reaches your insulation, which keeps your attic 20 – 30 degrees cooler and lets your insulation do its job at full R-value. It’s the most effective single upgrade for Irvine’s afternoon solar gain.
We carry 8 manufacturer brands across every major category: fiberglass from Owens Corning, CertainTeed, Johns Manville, and Knauf; mineral wool from Rockwool; open-cell and closed-cell spray foam from Icynene and Demilec; and recycled cellulose from GreenFiber. For Irvine’s mostly blow-in attic jobs, GreenFiber and Owens Corning are the most common. Your estimate will specify which brand we recommend for your attic, and why.
If we find crushed batts, rodent debris, water damage, or heavily dirty existing material, then yes, cleaning comes first. We remove the old material, air-seal every penetration we find, and then blow in or lay the new insulation. It costs more than a simple top-up, but it’s the only way to fix the thermal bypasses that older Irvine track homes are known for. Call (866) 605-6949 and we’ll walk through your attic condition over the phone.
