Insulation Company in West Hills, CA
Insulation in West Hills has to work harder than it does in most of Los Angeles. The mix of 1960s-to-1990s single-family homes, many still sitting under their original attic insulation, fights against San Fernando Valley summers that push cooling systems to their limit. That combination means the right insulation isn’t a luxury here, it’s the difference between an upstairs that stays livable in August and one that doesn’t. We’re Aspen Attic Insulation, and every West Hills job starts with a written price before any work begins, plus a 365-day written guarantee. Call us at (805) 309-1610.
Why West Hills Homes Are Different
West Hills sits in the western San Fernando Valley, where summer afternoons routinely climb past 95°F and the dry heat radiates straight through under-insulated attic spaces. Homes here were built in waves from the 1960s through the 1990s, and the earlier builds especially went up in an era when R-19 was considered plenty. Today, that leaves many ranch-style and Mediterranean-style houses with vented attics and wood-frame construction carrying far less thermal protection than current energy standards call for. The result is predictable: air conditioning units that run for hours without ever getting ahead, and bedrooms that feel 10 to 15 degrees warmer than the living room by 4 p.m.
One thing we hear constantly from West Hills homeowners is the cathedral ceiling problem. Homes built in the 1970s and 1980s often have vaulted or cathedral ceilings with minimal insulation installed at construction. There’s not much room up there to work with, and the thin original material has usually settled or degraded. Upstairs rooms become heat traps. We approach those jobs differently than a standard flat-attic blow-in, because the access points and the air movement in those ceiling cavities are not the same. Whole-home air sealing matters here too; the temperature swings between valley heat and cooler canyon evenings create stack effect that pulls conditioned air out through gaps around recessed lights, top plates, and attic hatches. An insulation job that ignores air sealing is leaving money on the table for any West Hills homeowner.
Our Main West Hills Services
Most West Hills calls we get are for two things: attic insulation upgrades and blown-in insulation to top off what’s already up there. Spray foam comes up often for cathedral ceilings and tricky rooflines. Each service has its own West Hills page below.
Attic Insulation in West Hills
Attic insulation in West Hills usually means removing old, compressed fiberglass or cellulose, air sealing the attic floor, and installing new material to a depth that actually matches the valley heat load. Many original West Hills attics have settled to R-19 or less, far below what a home with central air needs. We’re pulling out dust-caked batts from the 1970s and replacing them with fresh material that fills the joist bays properly. The difference in cooling costs is often immediate. Details on what we do, how long it takes, and what it costs are on the Attic Insulation in West Hills page.

Spray Foam Insulation in West Hills
Spray foam is the answer for West Hills homes with cathedral ceilings, open-beam construction, or attic spaces that can’t practically be air sealed any other way. Closed-cell foam builds an air barrier at the roofline, which matters in a climate where August attic temperatures can exceed 140°F. It’s a bigger investment than blown-in, but for certain West Hills layouts there’s no substitute. We pack it in existing roof cavities and around the venting in ranch-style homes where the roofline geometry makes traditional vented insulation underperform. Read about the approach on the Spray Foam Insulation in West Hills page.

Blown In Insulation in West Hills
Blown-in insulation, loose fibers shot into the attic cavity to fill every gap, works well for the broad, open attics common to West Hills ranch homes. It’s the fastest way to bring an under-insulated attic up to spec without major disruption. We use materials like GreenFiber and Owens Corning loose-fill, and the job usually runs from mid-morning to early afternoon. For attics with old batt insulation still in place, we can often blow over it after an inspection confirms it’s dry and structurally sound. See the Blown In Insulation in West Hills page for what’s involved.
