Insulation Company in Van Nuys, CA
Blown in insulation is the workhorse solution for Van Nuys homes, and it’s where most of our calls start. The San Fernando Valley’s dry heat and decades-old housing stock mean attic insulation settles, compresses, and stops doing its job faster than homeowners expect. East Los Angeles Insulation Co has served Van Nuys since 2018, and we carry the full range of blown-in products including GreenFiber cellulose and Johns Manville fiberglass. Call (866) 566-0304 to talk through what your attic actually needs.
Why Van Nuys Homes Are Different
Van Nuys sits in the hottest part of the San Fernando Valley, where summer afternoons push 105°F and the sun beats directly onto low-pitch and flat roofs that dominate the post-WWII housing stock. Homes built in the 1940s through 1960s across the 91401 and 91405 grids were framed with minimal wall insulation, and many still have whatever thin attic layer was code at the time, now compressed to a fraction of its original R-value. The dry, dusty Valley air accelerates settling in blown-in products, so insulation that looked adequate ten years ago is often performing at half its rated value today.
The flat and low-slope roofs common on mid-century Van Nuys tract homes create a specific failure mode: heat radiates through the ceiling well into the evening, even after outdoor temperatures drop. Adding more insulation without addressing radiant heat and attic ventilation means the ceiling still radiates warmth into living spaces all evening. That’s the difference between a contractor who understands Valley construction and one who just blows in product.
Our Main Van Nuys Services
Most Van Nuys homeowners call us for one of two things: fixing an attic that’s cooking the house all summer, or sealing and insulating with spray foam where air leaks are the real culprit. Here’s what each involves locally.
Attic Insulation in Van Nuys
Attic work in Van Nuys is a specialty, not an upsell. The low-pitch roofs on 1950s tract homes trap heat, and the dry air means blown-in products settle faster than they would in coastal Los Angeles. We inspect what’s already up there, measure the actual depth, check for rodent damage and old knob-and-tube wiring, and then recommend the right product whether that’s Johns Manville fiberglass, GreenFiber cellulose, or a radiant barrier retrofitted to the underside of the roof deck. Attic Insulation in Van Nuys covers the full process and what to expect.

Spray Foam Insulation in Van Nuys
Spray foam earns its keep in Van Nuys by sealing the air leaks that fiberglass and cellulose can’t address. Many 1940s-1960s homes here have original wood-frame construction with gaps around top plates, plumbing penetrations, and recessed light housings that let conditioned air escape while pulling hot attic air into the home. We install open-cell and closed-cell foam using Icynene and Demilec products, matched to the specific cavity and roof assembly. Spray Foam Insulation in Van Nuys explains the differences and where each makes sense.

Blown In Insulation in Van Nuys
Blown in insulation is the most common fix for Van Nuys attics, especially in the 91401 and 91405 tract homes where original insulation has compressed to near nothing. The dry San Fernando Valley air accelerates settling, so even homes insulated in the 1990s are often under-performing today. We install blown-in fiberglass and cellulose, typically GreenFiber or Johns Manville products, to bring attics back to a real R-value that actually holds up through a Valley summer. Head over to our Blown In Insulation hub for details on product options across every market we serve.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, or your upstairs rooms heat up noticeably faster than the rest of the house on summer afternoons.
What it costs in Van Nuys
Cellulose blown into a typical Van Nuys attic runs $1.60 to $3.30 per square foot depending on depth, access, and whether we’re topping off existing material or starting fresh.
How we do it
We air-seal the attic floor penetrations, install baffles at the eaves so soffit vents stay clear, then blow GreenFiber cellulose to the target depth with a calibrated machine.
Blown In Attic Insulation
Signs you need it
Your attic has uneven coverage, bare spots, or material that’s compressed and gray with dust, and your ceiling feels warm to the touch by late afternoon.
What it costs in Van Nuys
Full blown-in attic insulation for a standard Van Nuys ranch typically costs $1.70 to $3.40 per square foot, with most single-story homes landing between $2,800 and $6,500.
How we do it
We remove or top off the existing material, seal the bypasses that let hot air through, then blow fiberglass or cellulose to R-38 or better, verified with depth markers.
Loose Fill Insulation
Signs you need it
You have an older home with no wall insulation, or an attic with shallow, settled material that no longer reaches the top of the joists.
What it costs in Van Nuys
Loose fill insulation in Van Nuys runs $1.50 to $3.10 per square foot installed, with wall cavity retrofits priced per linear foot depending on access.
How we do it
We drill small access holes for wall cavities, blow the material to the correct density, patch cleanly, and for attics we blow to a uniform, measured depth.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Blown-in fiberglass attic insulation | $1.70 – $3.40 per sq ft |
| Blown-in cellulose attic insulation | $1.60 – $3.30 per sq ft |
| Air sealing + blown-in attic package | $3,200 – $7,500 total |
How long does blown in insulation last in Van Nuys?
Cellulose and fiberglass can last 20 to 30 years in Van Nuys, but the dry Valley air causes settling within the first few years. Most homes need a top-off or full replacement after 15 to 20 years to maintain their rated R-value.
Does blown in insulation help with Van Nuys summer heat?
Yes, but only up to a point. Blown-in insulation slows conductive heat gain, but on flat-roofed mid-century homes you also need ventilation and ideally a radiant barrier to stop the ceiling from radiating heat all evening. Call (866) 566-0304 for a straight answer on your roof type.

Yes, but older rental stock in the 91405 and 91406 grids often has asbestos-wrapped ducts and knob-and-tube wiring that need assessment before we blow insulation. We’ll flag any hazards and coordinate with the property owner on the right sequence of work.

What Van Nuys Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
- Gilbert Herrera"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."
- Jason Walsh"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
