Insulation Company in Irvine, CA
Woolsey Attic Insulation handles attic and spray foam insulation across Irvine, CA, with written pricing before any work starts. Irvine’s housing stock is unusual: nearly every home traces back to Irvine Company village phases, meaning a 1970s tract house in University Park and a 2015 build in Portola Springs need completely different things from an insulation crew. Summers push attic temperatures past 150°F, and many original attics now sit well below California’s current Title 24 energy standards. Call (325) 240-5411 for a free estimate and we’ll tell you exactly what your attic needs.
Why Irvine Homes Are Different
Irvine was built village by village, and the era your home belongs to dictates what’s up in the attic. The oldest villages, University Park from the early 1970s and Woodbridge from the late 1970s through the 80s, were insulated to the minimal codes of their day: R-19 attic and R-11 walls on 2×4 framing. Four decades later, the blown fiberglass in many of those attics has settled to two or three inches of compressed, dusty material, performing at a fraction of its original modest rating. Homes in Turtle Rock share the same profile. Newer villages like Northwood Pointe and Quail Hill were built with progressively better insulation, and current Portola Springs and Great Park Neighborhoods homes meet modern high-performance standards from the start. So two houses on the same street can have radically different needs depending on whether the street belongs to a 1980s phase or a 2000s phase.
Climate matters too. Irvine sits 10 to 15 miles inland, and afternoon highs in the mid-90s are routine all summer, with Santa Ana events pushing past 100°F. Attic temperatures in those conditions commonly exceed 150°F. The marine layer keeps overnight lows moderate, so the real problem is daytime heat gain pressing down through ceilings into living space. That’s why high-density attic insulation and radiant barrier upgrades deliver such noticeable results here compared to markets with larger temperature swings.
There’s a permit angle as well. Because Irvine has so much renovation activity across its maturing villages, permitted remodels routinely trigger Title 24 compliance upgrades. When a homeowner opens walls or replaces a roof under permit, the insulation has to meet current standards. We see this all the time in Woodbridge and University Park: a remodel that starts as a kitchen or bedroom project becomes an attic insulation retrofit because the code requires it.
Our Main Irvine Services
These are the two jobs Irvine homeowners call Woolsey Attic Insulation about most often, each with its own detailed page.
Attic Insulation in Irvine
Most of the attics we open in Woodbridge, University Park, and Turtle Rock look fine from the hatch but hold a thin, settled layer of the original blown fiberglass. We remove what’s left, air-seal the ceiling plane where possible, and install new blown-in insulation to current standards. In Irvine’s summer heat, a properly insulated attic keeps the afternoon heat from radiating down through ceilings, and the difference is noticeable the same week we finish. Read more about what’s involved on our Attic Insulation in Irvine page.
Spray Foam Insulation in Irvine
Spray foam insulation, a two-part liquid that expands on contact and seals gaps airtight, works well in Irvine homes with hard-to-reach attic geometry or homes with ductwork running through unconditioned space. It’s also a practical choice when a Title 24-triggered remodel requires a specific performance level in walls or roof lines, since foam delivers high R-value per inch in 2×4 bays where fiberglass tops out around R-13. See specific pricing and applications on our Spray Foam Insulation in Irvine page.

What pushes price up in Irvine is access: older Woodbridge and University Park homes often have tight scuttle holes and low attic clearances, which slows removal and installation. Homes in newer villages with truss attics and higher clearances tend to run lighter.

What Irvine Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov
