Insulation Company in Van Nuys, CA
Blown in insulation is the most common request we get from Van Nuys homeowners, and the reason is straightforward: the 1940s through 1970s ranch and tract homes across this part of the San Fernando Valley were built with thin batt insulation that has long since settled, compressed, or simply disappeared. In a climate where attic temperatures push past 140°F on summer afternoons, that missing layer means your air conditioner works overtime and your ceiling feels warm to the touch by 3 p.m. Hollywood Insulation Co has served Van Nuys since 2018, and we carry the material and method options to match the right fix to each home, whether that’s cellulose over existing batts, fiberglass in a clean attic, or a full removal and re-blow.

Why Van Nuys Homes Are Different
Van Nuys sits in the geographic center of the San Fernando Valley, and that specific location drives how insulation performs here. This is a heat island. Summer afternoons routinely push attic cavities past 140°F, and that heat doesn’t stay in the attic; it radiates down through the drywall into living spaces for hours after sunset. Insulation in Van Nuys is fundamentally about cooling-load defense, not the winter heat retention framing you’ll hear from insulation companies in colder markets.
The housing stock compounds the problem. Van Nuys is dominated by post-war single-story ranch and stucco tract homes built between the 1940s and 1960s, plus 1960s and 1970s apartment complexes along the Van Nuys Blvd and Sepulveda corridors. Many of those homes have low-pitch or flat roofs, which leave less attic air space for ventilation and put extra stress on whatever insulation is up there. A large share of these attics have original or thin batts that have been crushed under decades of storage boxes, exposed to decades of dust, or disturbed by rodent activity. We regularly see attics in the 91401, 91405, and 91406 ZIP codes where the original insulation is down to an inch or two of compressed fiberglass, effectively R-4 to R-6 when the home needs R-30 or more for this climate.
There’s also the electrical reality of these older homes. Knob-and-tube-era wiring shows up often in pre-1950 Van Nuys houses, and blowing insulation over it without proper assessment is a genuine safety concern. Our technicians know what to look for and how to route work around or address older wiring before any material goes in.
The classic Van Nuys call is a homeowner in a 1950s ranch off Van Nuys Blvd whose ceiling feels hot by mid-afternoon, whose AC runs non-stop from June through September, and whose attic inspection reveals the original insulation has been crushed to almost nothing. Pairing a blown-in insulation upgrade with radiant-barrier and ventilation work is the standard response here, because fighting Valley heat requires more than just more batts.
Our Main Van Nuys Services
Most Van Nuys homeowners contact us about one of two insulation methods, and each solves different problems in this climate.
Attic Insulation in Van Nuys
Attic insulation is the workhorse upgrade for Van Nuys ranches with accessible attics. In these homes, the attic floor is the primary thermal boundary between the 140°F attic air and your living space. We remove or top off existing batts depending on condition, address air leaks around can lights, plumbing penetrations, and chase ways, and install material matched to your attic’s actual state. Many Van Nuys attics also benefit from radiant-barrier installation to reflect heat before it ever reaches the insulation, which matters far more here than it does in cooler zip codes. Attic Insulation in Van Nuys covers the full scope, including what we do about ventilation and older wiring.
Spray Foam Insulation in Van Nuys
Spray foam earns its place in Van Nuys when the house has a low-pitch or flat roof, a converted attic, or ductwork running through unconditioned space. Open-cell Icynene and closed-cell Demilec systems give us two distinct approaches for different applications. Closed-cell foam adds structural rigidity and acts as a vapor barrier, which matters on flat-roof assemblies that see standing heat; open-cell is the right call when you want air sealing plus sound dampening at a lower material cost. Both perform dramatically better than batts at sealing the small leaks that let 140°F attic air push into your home. Spray Foam Insulation in Van Nuys explains when each system is the better fit.

Blown In Insulation in Van Nuys
Blown in insulation is the fastest, most cost-effective way to restore thermal performance to the attics of Van Nuys’s older homes. In a 1950s ranch where the original batts have compressed to nothing, blowing cellulose or fiberglass over the entire attic floor brings R-value back to modern standards in a single workday, without tearing out drywall or rebuilding anything. For most Van Nuys homeowners, that translates to a noticeable ceiling-temperature drop and real cooling savings starting the first summer after installation. Blown In Insulation is a core part of what we do, and we’ve installed it in hundreds of attics across 91401, 91405, and 91406.
Cellulose Insulation
Signs you need it
Your attic’s existing insulation is thin, patchy, or settled below the tops of the ceiling joists, and your upstairs ceiling feels warm by late afternoon.
What it costs in Van Nuys
Cellulose insulation in Van Nuys typically runs $1.50 to $3.50 per square foot installed, depending on the target R-value and whether old material needs removal first.
How we do it
We assess the attic, address any wiring or air-sealing issues, then blow GreenFiber recycled cellulose to an even depth across the entire attic floor using a calibrated machine that guarantees consistent density and R-value.
Blown In Attic Insulation
Signs you need it
You feel heat radiating from the ceiling line on summer evenings, your AC runs constantly, or an infrared photo of your ceiling shows bright hot bands where insulation is missing between joists.
What it costs in Van Nuys
Blown in attic insulation in Van Nuys generally runs $1,500 to $4,800 for a typical 1,200 to 2,000 square foot attic, including air sealing and baffles where needed.
How we do it
We seal air leaks at the attic floor, install ventilation baffles at the eaves, then blow insulation to the specified R-value across the full attic floor, working around and protecting any old wiring we’ve flagged.
Blown In Cellulose Insulation
Signs you need it
Your home was built before 1975 in Van Nuys and still carries its original batts, which are now compacted, dusty, or visibly degraded, and you want a recycled-content material.
What it costs in Van Nuys
Blown in cellulose insulation in Van Nuys typically runs $1.50 to $3.50 per square foot, with GreenFiber being our standard cellulose product for its recycled content and fire retardant.
How we do it
We remove or top up the existing material, blow GreenFiber cellulose to the target R-value, and verify the coverage with a depth gauge before we leave the attic.
Loose Fill Insulation
Signs you need it
Your attic has uneven coverage, bare spots, or areas where the old insulation has been pushed aside, and you need a single material that fills every gap and corner without cutting batts.
What it costs in Van Nuys
Loose fill insulation in Van Nuys runs $1.50 to $3.50 per square foot installed, depending on whether you choose cellulose or fiberglass and how deep the coverage needs to go.
How we do it
We blow loose fill across the full attic floor, working it around framing and obstacles, then measure depth at multiple points so every square foot hits the R-value you paid for.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Cellulose insulation (per sq ft installed) | $1.50 – $3.50 |
| Blown in attic insulation (typical 1,200 – 2,000 sq ft attic) | $1,500 – $4,800 |
| Loose fill insulation (per sq ft installed) | $1.50 – $3.50 |
How long does blown in insulation last in a Van Nuys attic?
Cellulose and fiberglass loose fill both hold their R-value for decades, but Van Nuys attics that see years of storage traffic, rodent activity, or roof leaks can compact or degrade material. An inspection tells you whether you need a top-up or a full re-blow.
Can you blow insulation over old knob-and-tube wiring in Van Nuys?
No, not safely. Wiring from the knob-and-tube era must be assessed and may need to be decommissioned or protected before insulation covers it. We flag this during the pre-installation inspection and handle it correctly. Call (866) 605-6949 to schedule an attic assessment.

What Van Nuys Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong
