Insulation Company in Van Nuys, CA
Blown in insulation solves a problem we see constantly in Van Nuys: post-war tract homes built before energy codes existed, with attic floors that radiate heat into living spaces from June through October. Most of these 1940s through 1960s houses in Van Nuys still have the original R-4 fiberglass batts, or nothing at all between the ceiling drywall and a 150°F attic. We’re Placentia Insulation, and we’ve served Van Nuys since 2018, matching blown-in cellulose, blown-in fiberglass, and loose fill materials to the specific attic geometry these mid-century homes present. Call (855) 773-6429 and we’ll tell you exactly what’s up there now, and what it should be instead.
Why Van Nuys Homes Are Different
Van Nuys is ground zero for the post-WWII building boom that reshaped the San Fernando Valley. The majority of housing stock here is single-story tract construction from the 1940s through the 1960s: stucco exteriors over wood framing, ventilated attics, and ceiling insulation that was minimal even by the standards of its day. Many of these homes still have bare attic floors with R-4 batts, and a surprising number have none at all. The original wood-shake roofs or first-generation asphalt shingles that many of these houses carry offer minimal attic ventilation, so whatever insulation exists has spent decades baking in trapped heat and absorbing moisture from the winter months. When we open these attics in Van Nuys, we routinely find batts that have compacted to a fraction of their original loft, or material that rodents have turned into nesting. The fix is usually full removal and a fresh blown-in application sized for the actual cavity depths.
The climate is the other half of the story. Summer attic temperatures in Van Nuys regularly push past 150°F, and that heat doesn’t stay in the attic. It radiates down through the ceiling assembly into bedrooms and living rooms, forcing air conditioners to run longer cycles just to hold a comfortable temperature. Mild winters mean heating is secondary; cooling efficiency is the primary driver for insulation work here. Homeowners in the 91470, 91401, 91405, and 91406 ZIP codes consistently tell us the same thing: some rooms are noticeably hotter than others, the AC runs constantly in the afternoon, and the upstairs or west-facing rooms never quite catch up. That’s an insulation problem before it’s an HVAC problem, and addressing the attic floor changes how the whole house behaves.
Our Main Van Nuys Services
Van Nuys homeowners call us most often about two services: re-insulating attics in aging tract homes, and sealing the building envelope with spray foam where traditional materials fall short. Both are covered below, with dedicated pages for the full detail.
Attic Insulation in Van Nuys
Attic insulation is the highest-impact energy upgrade available to Van Nuys homeowners, because the attic is where the Valley’s summer heat attacks first. We inspect the existing material, identify compaction, rodent contamination, or moisture damage, and build the attic floor back to current thermal performance standards. For the single-story stucco homes that dominate this area, a properly insulated attic can change the temperature delta between ceiling and living space by double digits. Every job starts with an honest assessment of what’s up there now, not a canned sales pitch. Full details on Attic Insulation in Van Nuys.
Spray Foam Insulation in Van Nuys
Spray foam does something batts and blown-in material cannot: it air-seals the surface it’s applied to. In Van Nuys, that matters most for converted garages, unvented attic assemblies, and rim joists that leak conditioned air year-round. The mid-century tract homes here often have uninsulated garages that were converted to living space decades ago, and those conversions rarely include proper thermal boundaries. We carry both open-cell and closed-cell options from Icynene and Demilec, so the foam chemistry is matched to the application rather than whatever happens to be on the truck.

Blown In Insulation in Van Nuys
Blown in insulation is the most practical retrofit material for Van Nuys attics, because it fills irregular cavities, covers existing batts, and reaches the corners where batt installation always falls short. In a 1950s tract house with a low-pitch roof and a shallow attic, loose fill gets where roll material cannot. We’ve spent years blowing GreenFiber cellulose and Owens Corning fiberglass into attics across Van Nuys, and the difference in upstairs room temperatures after a proper application is immediate. For the full scope of this service, see Blown In Insulation.
Cellulose Insulation
Signs you need it
Your attic has bare patches, compacted batts, or an upstairs that runs five to ten degrees hotter than the rest of the house in summer.
What it costs in Van Nuys
Blown-in cellulose for a typical Van Nuys attic runs $1,700 to $3,500 depending on square footage and target R-value.
How we do it
We remove or top up the existing material, seal the main air leaks at the attic floor, then blow GreenFiber cellulose to a consistent depth across the full cavity.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic ceiling are the hottest in the house, and you can feel heat radiating from the ceiling in the late afternoon.
What it costs in Van Nuys
Attic-only blown in applications in Van Nuys typically land between $1,200 and $3,000 for a standard single-story tract home.
How we do it
After clearing any failed material and sealing penetration points, we run a blower hose up to the attic and apply loose fill to a measured depth, working back toward the access point.
Loose Fill Insulation
Signs you need it
Your attic has uneven coverage, exposed ceiling joists, or existing insulation that has settled below the top of the framing.
What it costs in Van Nuys
Loose fill material costs shift with the selected material and R-value, with most Van Nuys projects finishing between $1,500 and $3,200.
How we do it
We verify the attic depth, calculate the material needed for the target R-value, and blow loose fill to an even, measured depth with no gaps or thin spots.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Blown in attic insulation (labor + material) | $1,200 – $3,000 |
| Blown in cellulose (whole attic) | $1,700 – $3,500 |
| Loose fill insulation (material-dependent) | $1,500 – $3,200 |
Does blown in insulation actually help in a Van Nuys summer?
Yes. Blown in material creates a consistent thermal barrier across the attic floor that blocks the 150°F attic heat from radiating into living spaces. Most homeowners report noticeably cooler upstairs rooms within a day or two of installation.
Can you blow insulation over the old stuff in my Van Nuys attic?
Sometimes, but not always. If the existing material is dry, not rodent-contaminated, and hasn’t compressed below usefulness, we can blow fresh material over it. If it’s compacted, wet, or full of pest debris, full removal comes first.
Brands We Service in Van Nuys
We work with eight insulation brands and stock the materials that matter for Van Nuys attics: GreenFiber cellulose for blown-in coverage, Owens Corning fiberglass for consistent thermal performance, and Icynene along with Demilec for spray foam where air sealing is the priority.
