Insulation Company in Van Nuys, CA
Blown in insulation is the most common retrofit we install in Van Nuys, and for good reason. The mid-century ranch homes and stucco apartment buildings that dominate this part of the San Fernando Valley were built when energy was cheap, and most original attics have either a thin, settled layer of fiberglass or nothing at all. Warm House Insulation Co has served Van Nuys since 2011, matching the right material to each home’s specific construction instead of pushing one product. Call (866) 361-3775 for a free estimate.
Why Van Nuys Homes Are Different
Van Nuys sits deep in the San Fernando Valley, where summer temperatures routinely cross 100°F and run 15 to 20 degrees hotter than coastal Los Angeles. The housing stock is overwhelmingly postwar tract construction from the 1940s through the 1970s: small single-story ranch homes and low-rise stucco apartment buildings along corridors like Van Nuys Blvd and near the Civic Center. Attics in these structures often reach 150°F in summer, and the original insulation, if any was ever installed, has usually settled or been pulled apart by decades of HVAC and electrical work. That leaves gaps and thin spots where heat pours straight down through the ceiling.
The condition of these attics changes the insulation recommendation. In a newer coastal home, a standard fiberglass batt might be fine. In a 1956 Van Nuys ranch with a low-pitch roof and an attic that cooks all afternoon, we typically recommend blown in cellulose or fiberglass at a depth that actually matters for cooling loads. Older exterior walls in Van Nuys often have no cavity insulation at all, which is a separate conversation, but the attic is almost always the first place to stop the heat. ZIP codes we cover include 91470, 91482, 91496, and 91499.
Our Main Van Nuys Services
Most Van Nuys homeowners call us about one of two things: an attic that needs to be brought up to a depth that actually reduces cooling costs, or a specific area that needs air-sealing and spray foam. Here is how each works in this city.
Attic Insulation in Van Nuys
Attic work in Van Nuys means dealing with low-pitch roofs, tight access hatches, and attics that are dangerously hot during the day. We start by checking the existing depth and condition, then recommend blown in material or a detailed air-seal-and-insulate approach depending on what we find. For homes off Van Nuys Blvd with original 1950s construction, this often means removing settled fiberglass and starting fresh. Read more on our dedicated Attic Insulation in Van Nuys page.

Spray Foam Insulation in Van Nuys
Spray foam comes up frequently for Van Nuys homeowners dealing with rooms over garages, additions with no attic access, or unsealed attic ductwork. We install both Icynene open-cell and Demilec closed-cell systems, and the choice depends on the specific job. Closed-cell adds structural rigidity and a vapor barrier, which matters in unconditioned spaces. See our Spray Foam Insulation in Van Nuys page for full details on how foam compares to blown in material in this climate.

Blown In Insulation in Van Nuys
Blown in insulation is the workhorse retrofit for Van Nuys attics because it fills the irregular bays and gaps left by settled fiberglass in 1950s and 1960s homes, and it can be installed to a depth that actually changes the cooling equation. We blow it over existing material or start clean after removing deteriorated batting, depending on what the attic shows us. Our installers work with both fiberglass and GreenFiber recycled cellulose, and we match the material to the attic’s access, depth target, and moisture history. If you’re comparing material options, the Blown In Insulation service page covers the method in detail.
Cellulose Insulation
Signs you need it
You want the highest recycled-content option available without giving up thermal performance, and your attic has settled fiberglass or gaps that keep letting heat through.
What it costs in Van Nuys
Cellulose insulation in Van Nuys typically runs $1,900 to $3,300 for a standard attic depending on depth and square footage.
How we do it
We remove any compromised material, prep the attic floor, and blow GreenFiber cellulose to the target R-value, keeping the product consistent and settling into every bay.
Blown In Attic Insulation
Signs you need it
Rooms under the attic run noticeably warmer than the rest of the house in summer, and looking up through the access hatch shows thin or bare areas.
What it costs in Van Nuys
Blown in attic insulation in Van Nuys typically costs $1,500 to $2,800 for a complete attic application in a standard postwar ranch home.
How we do it
We access the attic from inside or through the gable, air-seal any major penetrations, and use a mechanical blower to distribute material evenly to the required depth.
Blown In Cellulose Insulation
Signs you need it
You want a dense, sound-dampening fill that resists air movement better than fiberglass, and you prefer a recycled-material option.
What it costs in Van Nuys
Blown in cellulose in Van Nuys typically runs $2,000 to $3,500, with the higher end covering deeper fills in larger or awkward attics.
How we do it
We set up the blowing machine at the hose entry point and feed GreenFiber cellulose through, working methodically across the attic floor until the depth is uniform.
Blown In Fiberglass Insulation
Signs you need it
Your attic has good access and a simple layout, and you want a cost-effective blown material that reaches the specified R-value without adding much weight.
What it costs in Van Nuys
Blown in fiberglass in Van Nuys typically falls between $1,600 and $3,000 depending on the square footage and desired final depth.
How we do it
We lay down blocking or depth markers, run the hose through the attic in sections, and verify the final depth before finishing the job.
Loose Fill Insulation
Signs you need it
Existing insulation has settled below the top of the ceiling joists in spots, leaving uneven coverage that lets heat collect in the low areas.
What it costs in Van Nuys
Loose fill insulation in Van Nuys typically runs $1,400 to $2,700 for bringing an existing attic up to adequate depth.
How we do it
We inspect for moisture or electrical issues first, then blow loose fill across the low spots and over existing material until the attic is level at the target depth.

Can blown in insulation reduce my cooling bills in Van Nuys?
Yes. In Van Nuys’s extreme summer heat, a properly insulated attic reduces the amount of cool air your AC loses through the ceiling, which cuts runtime and monthly bills. The savings depend on what’s there now. Call (866) 361-3775 for an attic assessment.
How long does a blown in insulation job take in Van Nuys?
Most standard attic jobs in Van Nuys are finished in one day. Larger homes or attics that need old material removed first can run into a second day. We schedule around the heat in summer. Call (866) 361-3775 to check availability.

— Marco Salazar"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Maria Ramirez"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
