Insulation Company in Van Nuys, CA
Blown in insulation is the most common retrofit we perform in Van Nuys, because so many homes here were built in the 1950s and 1960s with attics that hold maybe R-11 of compressed fiberglass, if anything at all. When summer temperatures push past 100°F and attic spaces climb above 150°F, that thin layer does almost nothing. Even Air Insulation has served Van Nuys since 2018, matching each house to the right material from our eight-brand roster rather than pushing whatever is easiest to install.

Why Van Nuys Homes Are Different
Van Nuys sits in the San Fernando Valley, where the housing stock is dominated by mid-century tract homes built between the 1940s and 1970s. Many of these were constructed with 2×4 walls and slab-on-grade foundations, with builders treating insulation as an afterthought. Attics in these homes often hold a thin, settled layer of original fiberglass batts, sometimes just R-11, and in many cases homeowners have never had the space re-inspected. Some of the older homes still have knob-and-tube wiring in the attic, which has to be identified and addressed before any blown in material goes in.
The climate compounds the problem. Van Nuys has a hot semi-arid climate with long, dry summers that regularly exceed 100°F, and winter nights can drop into the 30s. That swing means insulation has to work in both directions: keeping conditioned air in during summer, and holding heat during winter. Attic temperatures in July routinely reach 150°F, which accelerates the breakdown of older insulation materials. Cellulose and fiberglass both lose effectiveness as they settle and get dust-contaminated over decades, and many Van Nuys attics we see are a perfect example of that.
What This Means for Insulation Work
The low-pitched roofs common on Van Nuys tract homes mean attic access is often tight. Blowing in insulation requires careful ventilation planning so you do not trap moisture against the roof deck. We inspect the existing ventilation, check for air leaks around can lights and plumbing penetrations, and then bring the attic up to modern R-values using a machine that can reach into the corners of a cramped attic without compressing the material. The goal is not just more insulation. It is insulation that performs through a Valley heat wave and a cold January night.
Our Main Van Nuys Services
Two services generate most of the calls we get from Van Nuys homeowners: attic insulation in houses that have never been retrofitted, and spray foam for rooms or additions where air sealing matters as much as thermal resistance. Here is what each involves in Van Nuys.
Attic Insulation in Van Nuys
Attic insulation is the highest-return energy upgrade most Van Nuys homes can make. The job usually starts with removing old, compressed batts, checking for knob-and-tube wiring or rodent damage, air sealing the attic floor, and then blowing in new material to R-38 or higher. Given how hot Van Nuys attics get in summer, proper ventilation baffles and sealing matter just as much as the insulation itself. Read more about how we handle this job at Attic Insulation in Van Nuys.
Spray Foam Insulation in Van Nuys
Spray foam is not always the right answer, but when air sealing or a difficult cavity calls for it, we have access to both Icynene open-cell and Demilec closed-cell formulations. In Van Nuys homes with flat roof sections or additions built without adequate insulation, spray foam can address both thermal and moisture concerns at once. We use it selectively, where the application justifies it. Details are on our Spray Foam Insulation in Van Nuys page.

Blown In Insulation in Van Nuys
Blown in insulation is the fastest way to bring a Van Nuys attic from under-insulated to a modern R-value without tearing out drywall. Most of the homes we retrofit in this area were built when energy was cheap and attics were barely insulated, so the existing material has settled or broken down, and rooms directly beneath the attic feel like ovens in summer. Blown in insulation, installed with specialized equipment that can work in low-clearance attics, adds thermal resistance quickly and evenly across the attic floor. It is the right retrofit for most Van Nuys tract homes. You can see more about the method on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has old fiberglass batts that have compressed to the thickness of a blanket, or rooms below the attic run noticeably hotter than the rest of the house in summer.
What it costs in Van Nuys
Cellulose insulation in Van Nuys typically runs $1.20 to $2.30 per square foot installed, depending on attic depth and access.
How we do it
We remove or level the existing material, seal air leaks, and then blow GreenFiber cellulose to the target R-value using a machine that leaves an even, settled layer.
Blown In Attic Insulation
Signs you need it
Your attic floor has bare spots or uneven coverage, and your HVAC system runs constantly during Van Nuys summer heat without holding a comfortable temperature.
What it costs in Van Nuys
Blown in attic insulation in Van Nuys averages $1,500 to $3,800 for a typical single-story tract home, depending on square footage and target R-value.
How we do it
We access the attic through the existing hatch, check for wiring and ventilation issues, then blow loose fill fiberglass or cellulose to an even depth across the entire floor.
Blown In Cellulose Insulation
Signs you need it
You are replacing old batt insulation and want a recycled-content material that fills irregular cavities better than fiberglass batts can.
What it costs in Van Nuys
Blown in cellulose runs $1.20 to $2.30 per square foot in Van Nuys, with dense-pack wall applications at the higher end of that range.
How we do it
We use GreenFiber cellulose, which is a recycled paper product treated for fire resistance, and blow it through a hose into the attic or wall cavity until it reaches the specified density.
Blown In Fiberglass Insulation
Signs you need it
You want an economical attic upgrade and your attic has adequate ventilation, so loose fill fiberglass is a cost-effective way to add R-value quickly.
What it costs in Van Nuys
Blown in fiberglass in Van Nuys costs $0.90 to $1.80 per square foot installed, depending on depth and attic accessibility.
How we do it
We blow loose fill fiberglass across the attic floor to the target depth, checking for consistent coverage and keeping material away from vents and fixtures.
Loose Fill Insulation
Signs you need it
Your attic has awkward corners or shallow joist bays where batts leave gaps, and you want insulation that settles into odd shapes without cutting and fitting.
What it costs in Van Nuys
Loose fill insulation in Van Nuys typically costs $0.90 to $2.10 per square foot, whether fiberglass or cellulose, depending on material and R-value.
How we do it
We run a blowing hose into the attic and distribute the material evenly across the floor, paying special attention to the perimeter where heat loss is most concentrated.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Blown in fiberglass (attic floor) | $0.90 – $1.80 per sq ft |
| Blown in cellulose (attic floor) | $1.20 – $2.30 per sq ft |
| Full attic retrofit (typical tract home) | $1,500 – $3,800 |
How long does blown in insulation last in Van Nuys?
Cellulose and fiberglass both last decades, but Van Nuys heat accelerates settling in the first year or two, which is why we install to account for some compression. A re-check every 5 to 10 years catches any loss of depth.
Can you blow insulation into existing walls in Van Nuys?
Yes. Dense-pack cellulose can be blown into closed wall cavities through small holes, which works well for Van Nuys homes built with empty 2×4 wall cavities. We check for knob-and-tube wiring before starting any wall work.
Brands We Service in Van Nuys
We work with eight manufacturers so the material matches the job, not our inventory. For Van Nuys homes we frequently install GreenFiber cellulose for attic retrofits, CertainTeed fiberglass for budget-conscious upgrades, and Icynene or Demilec spray foam where air sealing is the priority. Most materials are ready within days. See our brands.

FAQs About Insulation Company in Van Nuys
For insulation assessments and quotes we can usually be out within a few business days. During peak summer months, Van Nuys heat drives demand up, so calling early in the season helps you avoid a wait.
Most blown in and batt insulation retrofits do not require a permit, but if your home has knob-and-tube wiring that needs remediation first, an electrician’s permit may apply. We flag any permit concerns during the initial attic inspection.
Yes, especially if your attic currently has less than R-19. Bringing a Van Nuys attic to R-38 or R-49 reduces the heat load on your air conditioner, and many homeowners notice the difference within the first full billing cycle after installation.

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."
— Emily Gallagher"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Luis Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
