Insulation Company in Van Nuys, CA
Blown in insulation is one of the most practical upgrades for the older homes that fill Van Nuys. Most of the housing stock here went up between the 1940s and 1970s, when builders treated insulation as an afterthought. That means attics with a thin scattering of fiberglass, walls with nothing in them, and air-conditioned rooms that lose their cool by midafternoon. We match each Van Nuys house or apartment building to the right material, from GreenFiber cellulose to Johns Manville fiberglass, installed by one crew that does only insulation. If your rooms heat up fast and your AC never seems to catch up, call us at (855) 382-3925 for a free estimate.
Why Van Nuys Homes Are Different
Van Nuys sits in the middle of the San Fernando Valley, where summer temperatures over 100°F are a routine July condition, not a heat wave. The housing stock reflects the postwar building boom: single-story stucco ranch houses, low-rise apartment buildings, and rows of rental units off Van Nuys Blvd and the numbered streets. Most were built with uninsulated wood-frame walls, low-pitch attics, and single-pane windows. In the summer, attics in Van Nuys regularly hit 140°F, and hot air filters down through ceiling cracks into living spaces. Older ductwork often runs through that same attic heat, so cooled air warms up before it reaches a bedroom.
The practical result: cooling-season performance is the whole game here. Freeze protection barely matters. Radiant attic control, air sealing, and deep attic insulation do. We also work with a lot of landlords and apartment-building owners in Van Nuys, who call us when tenants start complaining about rooms that won’t hold a temperature. In many cases, adding insulation beats upgrading the AC unit, and it costs far less.
Our Main Van Nuys Services
Most Van Nuys homeowners and building owners call us about two things: attics that are bleeding cool air and walls or crawl spaces that need a more complete air seal. Here is what each one involves locally.
Attic Insulation in Van Nuys
In Van Nuys, attic work starts with the reality that many attics have almost nothing in them. We inspect what is up there, remove anything degraded, seal the gaps where conditioned air leaks into the attic, and then bring the insulation up to a level that actually holds against 100°F summers. Radiant barrier and air sealing matter as much here as the insulation itself. Read more about how we approach it on our Attic Insulation in Van Nuys page.
Spray Foam Insulation in Van Nuys
For walls, rim joists, and crawl spaces in older Van Nuys construction, spray foam does what batts cannot: it fills the irregular cavities in 1950s and 1960s framing and stops air movement, not just heat transfer. We spray open-cell and closed-cell systems from Demilec, one of the most tested brands in the industry, and it is often the single biggest comfort upgrade a Van Nuys ranch home can get. Details are on our Spray Foam Insulation in Van Nuys page.

Blown In Insulation in Van Nuys
Blown in insulation is the fastest, least disruptive way to add serious insulation to an existing Van Nuys home, and it is especially well suited to the low-pitch attics and odd framing cavities common in 1950s and 1960s construction here. Loose-fill material flows into the gaps that batts cannot reach, covering the entire attic floor or filling wall cavities without tearing out drywall. For Van Nuys homeowners dealing with 140°F attic heat radiating down into living spaces, blown in cellulose or fiberglass at the right depth changes how the whole house feels by late afternoon. We install both GreenFiber cellulose and Johns Manville fiberglass loose-fill, and we match the material to your attic and your budget rather than defaulting to whichever is cheapest. Learn more about the method on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic has thin, patchy insulation or none at all, and upstairs rooms run 10 to 15 degrees hotter than the rest of the house by late afternoon.
What it costs in Van Nuys
Blown cellulose in Van Nuys attics typically runs from $1.20 to $2.30 per square foot, depending on depth, access, and how much old material must come out first.
How we do it
We prep the attic, air-seal bypasses, then blow GreenFiber cellulose to a consistent depth over the entire attic floor, including around ductwork and framing.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic get warm by midday, and your air conditioner runs constantly from noon to sunset without holding the thermostat setting.
What it costs in Van Nuys
Blown in attic insulation in Van Nuys ranges from $1.50 to $3.80 per square foot, with old insulation removal adding to the job when it is needed.
How we do it
We inspect the existing attic insulation, remove or top it up as needed, seal air leaks, and blow loose-fill to the target depth for Van Nuys cooling loads.
Blown In Cellulose Insulation
Signs you need it
Your energy bills spike every summer, and you can feel heat radiating from the ceiling even after the sun goes down.
What it costs in Van Nuys
Expect to pay from $1.20 to $2.30 per square foot for blown in cellulose in Van Nuys, with GreenFiber recycled-content material as a standard option.

We blow GreenFiber cellulose into attics or dense-pack it into wall cavities, using a fiberglass-reinforced hose system that reaches tight Van Nuys attic corners.
Loose Fill Insulation
Signs you need it
Your attic has settled fiberglass or rock wool from decades ago, and the coverage is uneven, leaving bare spots that show up as hot patches on the ceiling below.
What it costs in Van Nuys
Loose fill insulation in Van Nuys attics ranges from $1.50 to $3.80 per square foot, including air sealing around attic penetrations.
How we do it
We top up settled material or start fresh with loose fill, blowing it to a consistent level that closes gaps and reduces the radiant load on your ceilings.

What Van Nuys Customers Say
"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."
— Colleen Vaughn"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Amanda Sullivan"Spray foam in the rim joists in the basement. The cold floors above them are gone."
