Insulation Company in Van Nuys, CA
Blown in insulation is the most practical retrofit for Van Nuys’ postwar tract homes, where original attics rarely have more than a few inches of settled, rodent-soiled material. We install loose-fill fiberglass and cellulose at depths that actually change the cooling bill, because this part of the San Fernando Valley gets punishing dry heat from June through October. Call (866) 271-1602 for a free attic assessment and an honest recommendation on material.
Why Van Nuys Homes Are Different
Van Nuys is ground zero for San Fernando Valley’s postwar 1940s-1950s tract housing. Thousands of small, single-story, wood-frame bungalows were built for returning GIs with little or no wall or attic insulation. In 2026, that means nearly every job here is a full retrofit, not a new install. The flipping and rental density around Van Nuys means owners want attic blow-ins and radiant-barrier fixes that actually move the summer cooling bill, not premium spray-foam packages.
The housing stock also creates specific technical conditions. Many of these homes have low-pitch or flat roofs and shallow attics that can exceed 140°F during installation. In the old tract homes, the original attic insulation is often bare-faced kraft paper or thin rock wool that has been crushed, settled, and rodent-soiled. Technicians routinely find rodent runs, chewed vapor barriers, and knob-and-tube wiring that must be re-insulated or addressed before blowing in new material. Add in a scatter of mid-century small apartment buildings and light industrial sheds with flat-roof, low-slope work, and you have a city where attic access varies wildly from one street to the next.
Our Main Van Nuys Services
Most Van Nuys homeowners call us about two things: getting their under-insulated attic up to current standards, and sealing specific problem areas with spray foam. Here’s what each involves in this city’s housing stock.
Attic Insulation in Van Nuys
Most Van Nuys bungalows were built with empty or barely filled attics, and the shallow roof pitch means heat loads hit hard. We pull out the old kraft paper, rat runs, and settled rock wool, address knob-and-tube wiring concerns with an electrician when needed, then blow in new material to the correct R-value for the Valley’s climate. Radiant barrier is often the right add-on here. Read more on our dedicated Attic Insulation in Van Nuys page.
Spray Foam Insulation in Van Nuys
Spray foam earns its cost in Van Nuys when there’s a specific air-sealing problem: a flat-roof addition, a converted garage, floor joists over a crawlspace, or ductwork sweating in the attic. Closed-cell foam from Icynene or Demilec performs well here where heat gain is severe and space is tight. See the full material comparison and Van Nuys-specific pricing on our Spray Foam Insulation in Van Nuys page.

Blown In Insulation in Van Nuys
Blown in insulation is the fastest, most cost-effective way to fix a Van Nuys attic that was under-insulated in 1949 and never touched again. Loose-fill fiberglass or cellulose can be installed over existing material in a single visit for most single-story bungalows, cutting the heat that pours down through the ceiling from June through October. It’s the workhorse service for this city, and we carry both Blown In Insulation material types so the choice is driven by your attic, not our inventory.
Cellulose Insulation
Signs you need it
Your attic has settled material below the tops of the joists, your upstairs rooms run 10 to 15 degrees hotter than the rest of the house, or you want a recycled-content option for an older Van Nuys home.
What it costs in Van Nuys
Cellulose Insulation in Van Nuys typically runs $1.10 to $1.60 per square foot installed, depending on existing material depth and prep.
How we do it
We remove rodent-soiled or crushed material where needed, seal ceiling penetrations, and blow GreenFiber cellulose to the target depth using a two-person hose-and-machine setup.
Blown In Attic Insulation
Signs you need it
Your Van Nuys home’s attic has bare kraft-faced batts or thin rock wool from the original 1940s-1950s build, and summer cooling costs keep climbing.
What it costs in Van Nuys
Blown In Attic Insulation in Van Nuys typically runs $1.20 to $2.10 per square foot, with full retrofit scope varying by attic access and wiring conditions.
How we do it
We air-seal the attic floor, install baffles at the eaves, and blow fiberglass or cellulose to the R-value appropriate for the Valley’s heat load.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Cellulose Insulation (per sq ft) | $1.10 – $1.60 |
| Blown In Attic Insulation (per sq ft) | $1.20 – $2.10 |
| Blown In Fiberglass Insulation (per sq ft) | $0.90 – $1.50 |
Is blown in insulation worth it in Van Nuys?
Yes. For a 1940s-1950s tract bungalow with a shallow, uninsulated attic, a blow-in is the lowest-cost retrofit that meaningfully cuts summer heat gain. Most Van Nuys jobs pay for themselves in reduced cooling costs within a few years.
Can you blow insulation over old material in Van Nuys attics?
Often yes, but not always. Fiberglass or cellulose can be blown over existing material if it’s dry and uncontaminated. Rodent-soiled or crushed material should be removed first. Call (866) 271-1602 for an attic assessment and a straight answer.

What Van Nuys Customers Say
"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
