Fast, Reliable Attic Insulation Across Van Nuys
Attic insulation in Van Nuys is primarily about beating the heat. A typical attic here hits 140°F or more on a July afternoon, and that heat pours down through your ceiling, making your AC work far harder than it should. We fix that. Hollywood Insulation Co installs and replaces attic insulation across Van Nuys, including 91401, 91405, 91406, and the surrounding Valley, with a focus on cooling-load defense: radiant barriers, ventilation, and blown-in insulation that actually holds its R-value. If your ranch home off Sepulveda or Van Nuys Blvd feels like an oven upstairs, call (866) 605-6949 for a free estimate.
Why Hollywood Insulation Co Is Van Nuys’s Preferred Attic Insulation Company
We’re insulation specialists, not a general contractor who happens to carry batts. That distinction matters in Van Nuys, where post-war ranch homes present specific challenges: low-pitch roofs, minimal attic ventilation, original insulation crushed flat, and wiring that predates modern code. Our team knows these houses because we work on them every week. We carry eight manufacturer brands spanning fiberglass, mineral wool, spray foam, and recycled cellulose, so the recommendation you get is based on what your attic actually needs, not whatever is on the truck.
Noel Camacho leads our crew, and his approach is straightforward: diagnose the attic first, then match the material. That’s why a 1950s ranch off Van Nuys Blvd might get Owens Corning blown-in fiberglass with a radiant barrier, while a 1970s apartment building along Sepulveda gets GreenFiber cellulose for its fire resistance and sound control. Call (866) 605-6949 and we’ll schedule a time to look at your attic, usually within a few days. For more on our full range of work, see our Attic Insulation page.
Attic Insulation Removal in Van Nuys
Attic Insulation Removal in Van Nuys is the first step on most older homes here, not an optional add-on. The reason is simple: decades of Valley heat, foot traffic, and storage have flattened original batts to an inch or two, which means whatever R-value they once had is gone. We remove the old material completely, inspect what’s underneath, and prepare the space for new insulation. A full removal on a typical 1,200 to 1,800 square foot Van Nuys ranch runs $1,100 to $2,300, depending on attic depth and access. If knob-and-tube wiring is present, we work carefully around it and flag any areas that need an electrician’s attention before new insulation goes in.
When Removal Becomes Necessary
If your attic insulation looks settled, matted, or dusty, removal is usually the right call. Blowing new insulation on top of compressed, ineffective material just buries the problem. We handle removal with commercial vacuums and containment, so your living space stays clean while the old material comes out.
Removal for Older Homes and Rentals
Van Nuys has a large stock of 1960s and 1970s apartment buildings along the Van Nuys Blvd and Sepulveda corridors. Attic insulation removal in these buildings often requires working around ductwork, old wiring, and limited access. We have done enough of these jobs to move quickly without compromising safety.
Insulation Contractors in Van Nuys
Insulation Contractors in Van Nuys fall into two camps: general contractors who install insulation as a side service, and dedicated specialists. We are the second kind. When you hire us, every person on the job lives in this trade. That focus matters in a city where the local building stock demands real diagnostic skill. Nearly every Van Nuys home built between 1945 and 1970 has inadequate attic ventilation, and many still have original insulation or none at all in spots. A specialist sees those problems. A generalist often doesn’t.
Attic Inspections and Recommendations
We start with an attic inspection that looks at existing R-value, ventilation, air sealing, and any electrical concerns. Then we give you a written recommendation with a price. No pressure. If the right answer is a top-up rather than a full removal, we tell you that. Expect a typical blown-in attic insulation project in Van Nuys to run $1,800 to $3,600 for a full attic, while a top-up of 6 to 10 inches runs $900 to $2,200.
Radiant Barrier and Ventilation Work
Attic insulation in Van Nuys is incomplete without considering radiant barriers and ventilation. A radiant barrier stapled to the underside of the roof deck reflects heat back out, which can keep attic temperatures 20 to 30 degrees lower. For most Van Nuys ranches, we recommend pairing blown-in insulation with a radiant barrier and ridge or soffit vents. This is the cooling-first approach that actually makes a difference here.
Trusted Brands We Service in Van Nuys
We install insulation from eight recognized manufacturers, including Owens Corning, Icynene, Demilec, and GreenFiber. For Van Nuys homeowners, that means the material recommendation is honest. Icynene open-cell spray foam works well for sealing irregular attic cavities. Demilec closed-cell foam delivers high R-value per inch and moisture resistance. GreenFiber recycled cellulose suits homeowners who want a high recycled-content, fire-resistant option. Because we carry all of these, we don’t push one over another. The house decides. See our Attic Insulation in Van Nuys page for more local detail.
Common Attic Insulation Problems We See in Van Nuys Homes
- Crushed original batts. Decades of storage, foot traffic, and dust have pressed 1950s and 1960s batt insulation down to an inch or two. R-value is effectively zero, and the upstairs rooms show it.
- No radiant barrier or ventilation. Van Nuys attics routinely exceed 140°F without one. That heat soaks into the ceiling and forces your AC to run constantly from June through September.
- Knob-and-tube wiring in the attic. Many post-war Van Nuys homes still have active knob-and-tube circuits running through the attic. Blowing insulation directly over this wiring without careful separation creates a fire risk. We flag it and work around it.
- Missing or ineffective attic baffles. Poor baffle installation blocks airflow from soffit vents, turning a potentially vented attic into a heat trap. We check and install baffles as part of most attic upgrades.

FAQs About Attic Insulation in Van Nuys
No, and we don’t recommend it. Blowing new insulation over crushed, compressed batts leaves the old material still underperforming and can trap moisture or dust. In a Van Nuys ranch, we remove the old insulation first, then blow fresh material to the recommended R-value. That gives you the full performance you’re paying for. Call (866) 605-6949 for a removal and replacement quote.
We work around it carefully, never covering it directly with insulation. Knob-and-tube wiring needs air space to dissipate heat. If we find active knob-and-tube in your Van Nuys attic, we flag it, coordinate with a licensed electrician if updates are needed, and only then proceed with insulation. This is standard practice on many 1940s and 1950s homes in 91405 and 91406.
For most Van Nuys attics, we recommend R-38 to R-49, which is the Department of Energy’s guidance for our climate zone. But R-value alone is not enough here. We pair that with a radiant barrier and proper ventilation, because the cooling season is what drives your energy bills. Heat gain, not heat loss, is the enemy in Van Nuys.
Yes. Radiant barriers install directly under the roof deck and work on low-pitch and flat roofs, though flat roofs may need a slightly different attachment method. In Van Nuys, a radiant barrier typically keeps attic temperatures 20 to 30 degrees lower, which directly reduces the heat load on your AC. We quote radiant barriers as part of most attic insulation upgrades here.
Yes. We handle attic insulation removal for small apartment buildings and multifamily properties throughout Van Nuys, including the older stock along Van Nuys Blvd and Sepulveda. These jobs often involve tighter access and more obstructions, but our crews are experienced with them. Call (866) 605-6949 to schedule a walkthrough.
