Insulation Company in Van Nuys, CA
Blown in insulation is the workhorse upgrade for Van Nuys homes built between the 1940s and 1960s, where original attic coverage has settled to a thin, ineffective layer. Brea Insulation specializes in exactly this: pulling out degraded loose-fill, air sealing the attic floor, and blowing in fresh cellulose or fiberglass that holds R-value through Valley summers that push past 100°F. We carry eight manufacturer lines so the material matches the house, not the truck. Call (866) 858-4033 to schedule a free attic assessment in Van Nuys.
Why Van Nuys Homes Are Different
Van Nuys sits dead center in the San Fernando Valley, where summer temperatures run 10 to 15 degrees hotter than what Santa Monica feels on the same afternoon. That heat loads directly onto low-pitch roofs over single-story ranch and cottage homes from the 1940s through 1960s. Most of these wood-frame, stucco-sided houses left the builder with an inch or two of fiberglass batt in the attic, if that. Sixty years later, the material has settled, compressed, and stopped doing much of anything. Walk through the neighborhoods around Van Nuys Boulevard or up toward Sepulveda Basin and you’ll see the same rooflines repeated block after block: shallow attics, attached garages, and uninsulated knee walls where conditioned air leaks straight into a 140-degree attic in August. The result is a house that costs $500 a month to cool in summer and still feels stuffy at 3 p.m. Insulation upgrades here pay back faster than almost anywhere else in LA County because the temperature delta is so extreme.
Dust and pollen from the Valley floor add another layer to the problem. Gaps around ceiling fixtures, attic hatches, and top plates pull that particulate into living space all year. A proper air sealing pass before insulation goes in is as much about indoor air quality as it is about energy load. Winter nights dropping into the 40s mean the same attic that overheats in July also bleeds heat in January, so the material we choose has to handle both directions of thermal movement.
Our Main Van Nuys Services
Most Van Nuys homeowners reach out about two jobs: upgrading a worn-out attic and air sealing with spray foam. Both are covered under one roof here.
Attic Insulation in Van Nuys
Attic insulation in Van Nuys usually means removing whatever settled material is up there, sealing the penetration points, and installing fresh coverage rated for a hot semi-arid climate. Homes from the 1950s and 60s rarely have anything close to modern R-value, and the low-pitch roofs make access tight, so technique matters. We handle the full attic insulation scope on this page: Attic Insulation in Van Nuys.
Spray Foam Insulation in Van Nuys
Spray foam earns its keep in Van Nuys by sealing the air leaks that fiberglass alone can’t touch. Older tract homes have dozens of small gaps where attic air migrates into living space, and closed-cell foam closes those while adding R-value per inch that works in shallow roof cavities. We install Icynene and Demilec systems. Details on the full spray foam scope live at Spray Foam Insulation in Van Nuys.

Blown In Insulation in Van Nuys
Blown in insulation is the most common upgrade we perform in Van Nuys, and for good reason. The original loose-fill cellulose in these 1940s-to-1960s tract homes has settled to two or three inches and is often laced with rodent droppings and decades of accumulated dust. Removing that material, sealing the attic floor, and blowing in fresh fiberglass or cellulose from our Blown In Insulation line restores full thermal coverage and cuts summer cooling costs dramatically. In a climate where attics hit 140 degrees in July, a properly blown attic is the single highest-impact change a homeowner can make.

What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Cellulose attic insulation (1,200 sq ft) | $1,450 – $2,500 installed |
| Blown fiberglass attic insulation | $1,500 – $3,500 installed |
| Full removal + air sealing + new blown-in | $2,500 – $4,500 installed |
How long does blown in insulation last in Van Nuys?
Cellulose and fiberglass both hold their R-value for 20 to 30 years, but only if the attic stays dry and the material isn’t disturbed. In Van Nuys, the bigger threat is rodent activity in old attics, which compresses and contaminates loose-fill over time.
Can you blow insulation over what’s already in my Van Nuys attic?
Sometimes, if the existing material is dry, uncontaminated, and reasonably even. More often in Van Nuys homes from the 50s and 60s, the old cellulose has settled to the point where removal and a fresh start gives better results. Call (866) 858-4033 and we’ll tell you which route fits your attic.
