Insulation Company in North Hills, CA
Blown in insulation is the most common fix we recommend for North Hills homes, because the housing stock here is exactly the kind that benefits most from it: 1950s and 1960s single-story tract homes with original R-11 batts that have flattened out under decades of San Fernando Valley heat. When attic temperatures top 150°F in summer, thin or compressed insulation lets that heat pour straight down into living space, and your air conditioner runs almost nonstop trying to keep up. We’re a dedicated insulation contractor, not a generalist, and we’ll tell you honestly whether blown in fiberglass, cellulose, or another method makes sense for your specific roof and attic.

Why North Hills Homes Are Different
North Hills sits in one of the hottest corners of the San Fernando Valley. Summer days above 100°F are common, and attic temperatures routinely exceed 150°F by mid-afternoon. That changes the entire insulation conversation: almost every job we do in the 91343 and 91393 ZIP codes is driven by cooling load, not heating. The goal is to keep radiant heat out of the living space below, which means attic insulation is doing the heavy lifting in a way it doesn’t have to in coastal communities or colder climates.
The housing stock reinforces this. Most homes here are postwar ranch tract builds from the 1950s through the 1970s, with low-pitch composition shingle roofs and accessible attics. The original insulation, where it exists at all, is typically R-11 fiberglass batt or less. In many attics we open, those batts have slumped, torn, or been pushed aside by past workers. Some older homes along the Sepulveda corridor and in parts of the 91343 area still have bare joist cavities above the ceiling drywall. You’d never know until someone pops the attic hatch. Add in the valley’s dry heat and the regular presence of rodents nesting in older insulation, and most North Hills work we do is re-insulation and air sealing: removing compromised material, sealing the ceiling plane, and blowing in fresh loose fill at the correct depth.
Our Main North Hills Services
Two services account for most of what North Hills homeowners ask us about: attic insulation and spray foam. Both address the same underlying problem – a hot attic driving heat into the home – but they solve it in different ways and at different price points.
Attic Insulation in North Hills
Attic insulation is the highest-impact upgrade for most North Hills homes because the attic is where the largest share of heat gain happens. We remove old, compressed, or rodent-damaged material, air-seal the ceiling plane, and install new insulation matched to your attic’s depth and your cooling needs. Many homes we see still have the original R-11 batts from the 1960s, which is far below what the valley climate calls for. Learn more about how we approach Attic Insulation in North Hills.
Spray Foam Insulation in North Hills
Spray foam is a different tool for the same battle. In North Hills attics with ductwork, knee walls, or odd framing, open-cell or closed-cell foam can seal air leaks that loose fill can’t reach. It’s also the right call for homes where the attic is used for storage or has awkward access. We install Icynene and Demilec foams, both open-cell and closed-cell, and we’ll tell you when foam is worth the higher cost and when blown in will do the job just as well. Read about the specifics on our Spray Foam Insulation in North Hills page.

Blown In Insulation in North Hills
Blown in insulation is our most requested service for North Hills attics, and the reason goes back to how these homes were built. Most were constructed between the 1950s and 1970s with thin original fiberglass batts, and after 50 or 60 years in a climate where attics spend half the year above 140°F, that material is nearly useless. Blown in loose fill lets us add consistent, full-depth coverage across the entire attic floor, filling the gaps and bare joist cavities that batts never covered in the first place. It’s also the most cost-effective way to bring an older North Hills attic up to current R-value targets without tearing anything out. For more detail on the method, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has old, settled insulation, gaps around ceiling fixtures, or rooms that heat up unevenly even with the AC running.
What it costs in North Hills
Blown in cellulose for a typical North Hills attic runs from $1.20 to $2.10 per square foot, with removal of old insulation adding $1 to $2 per square foot.
How we do it
We prep the attic by sealing air leaks, then blow GreenFiber recycled cellulose to a consistent depth that hits your target R-value, typically R-38 to R-49 in this climate.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel 8 to 15 degrees warmer than the rest of the house on hot afternoons, and your AC runs in long cycles without fully cooling.
What it costs in North Hills
Blown in attic insulation in North Hills averages $1.20 to $2.00 per square foot for new loose fill, with the total job on a 1,200-square-foot attic typically landing between $1,500 and $2,500.
How we do it
We inspect the existing depth, remove or top off as needed, seal the ceiling plane, and blow loose fill across the full attic floor to a uniform depth with attention to eaves and exterior walls.
Blown In Cellulose Insulation
Signs you need it
You want a recycled-content option, or you have an older attic where dense packing into odd cavities and around framing is the practical path to better coverage.
What it costs in North Hills
Blown in cellulose runs $1.20 to $2.10 per square foot, which for most North Hills attics lands the full install in the $1,300 to $2,700 range after materials and labor.
How we do it
We use GreenFiber cellulose, a recycled paper-based product treated for fire and pest resistance, and blow it to your target depth with a machine calibrated for the material’s density.
Loose Fill Insulation
Signs you need it
You have an accessible attic with open joist bays, and you want fast, even coverage that conforms to whatever’s already up there.
What it costs in North Hills
Loose fill insulation jobs in North Hills typically fall between $1.20 and $2.10 per square foot, depending on material and target R-value.
How we do it
We lay down a consistent layer of loose fill across the attic floor, working around existing framing and venting, and use depth markers so you can see exactly what you’re paying for.
What Blown In Insulation Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Blown in fiberglass (new attic install) | $1.20 – $2.00 per sq ft |
| Blown in cellulose (new attic install) | $1.20 – $2.10 per sq ft |
| Removal of old blown in insulation | $3.50 – $5.00 per sq ft |
Prices above cover typical North Hills attics with easy access and standard framing. Your exact number depends on attic size, target depth, and whether we’re removing compromised material first. We quote a fixed price before any work starts so there’s no surprise at the end.
Is blown in insulation worth it in a North Hills 1950s home?
Yes, it’s typically the single best energy upgrade you can make. These homes were built with minimal attic insulation, and blowing in a full layer to R-38 or R-49 directly attacks the valley’s main problem: radiant heat moving from attic to living space. Call (855) 382-3451 for a free attic assessment.
Can you blow insulation over old batts in a North Hills attic?
In many cases yes, as long as the existing batts aren’t rodent-damaged, wet, or compressed to the point of trapping heat. We inspect first and tell you if topping off makes sense or if removal is the better long-term move in this climate. Estimates are free.
Brands We Service in North Hills
We stock and install products from eight manufacturers, which matters when a North Hills attic has a specific problem to solve. We carry Owens Corning and Johns Manville for fiberglass, GreenFiber for recycled cellulose, and Knauf when a project calls for it. Having multiple lines means we’re not pushing one product into every house. Common materials are on hand for same-week installs in North Hills. See the full range on our brands page.

We give you one fixed price before work starts, and that number doesn’t change unless you add scope.
