Insulation Company in North Hills, CA
Blown in insulation is the most common fix we install in North Hills, because so many homes here were built between the 1950s and 1970s with thin or collapsed attic insulation that was never meant to handle a San Fernando Valley summer. When attic temperatures climb past 150°F, that heat pushes straight down into living spaces, and the west-facing bedrooms become almost unusable by late afternoon. We’re Orange County Insulation, an insulation-only contractor, and we’ve served North Hills since 2013. Call (877) 680-3557 for a free estimate on bringing your home up to modern R-values.
Why North Hills Homes Are Different
North Hills sits in a known heat island inside the San Fernando Valley. The 91343 ZIP is mostly post-WWII ranch and mid-century tract homes: single-story stucco, wood-frame walls, low-pitch roofs, and attached garages. Many still carry their original mineral-wool batts, which by now have settled, torn, or been nested in by rodents. Cooling load dominates here, not heating. That changes the insulation conversation entirely. A home in North Hills needs high-R attic coverage, real air sealing, and often a radiant barrier before any other upgrade makes sense.
The dry heat also works against older insulation. Sealants crack. Batts lose loft. Dust and debris settle into the fibrous material and reduce its ability to slow heat transfer. We regularly find attics in the 91343 tract where the original insulation measures R-11 or less, when current code for this climate zone calls for R-38 or higher. That gap is why second floors stay hot and air conditioners run constantly from June through October. The fix is not a patch. It’s air sealing the attic floor, then blowing in fresh insulation to a uniform depth that actually matches what this Valley climate demands.
West-facing rooms deserve special attention in North Hills. A July afternoon pushes attic temperatures past 160°F, and that radiant heat loads directly onto the ceiling below. Blown-in insulation alone helps, but pairing it with air sealing stops the stack effect that pulls hot attic air down through can lights, electrical penetrations, and wall top plates. This combination is the single highest-impact improvement most North Hills homeowners can make.
Our Main North Hills Services
Homeowners in North Hills call us most often about two jobs: upgrading attic insulation in an older Valley home, and sealing the building envelope with spray foam where air leakage is the real culprit. Here’s what each one looks like in this area.
Attic Insulation in North Hills
Most attic jobs in North Hills start with removing the old, failed material, then air sealing the attic floor before new insulation goes in. The low-pitch roofs on 1950s ranch homes leave tight working space, so we send crews who know how to move through those cramped attics without damaging the ceiling below. The heat here means we schedule attic work early in the morning when possible, and we match the insulation type to your roof structure and budget. See the full scope on our dedicated page: Attic Insulation in North Hills.
Spray Foam Insulation in North Hills
Spray foam earns its keep in North Hills when a home has uninsulated crawlspaces, knee walls, or attached-garage conversions that leak air constantly. Closed-cell foam also adds structural rigidity and acts as an air barrier in one step, which matters in older wood-frame construction. We carry both Icynene open-cell and Demilec closed-cell, so the material choice follows your home’s actual condition, not a sales script.

Blown In Insulation in North Hills
Blown in insulation is the workhorse solution for North Hills homes built in the 1950s through 1970s, because it can be installed quickly over existing attic floors and reaches the awkward corners and shallow eaves that batts simply can’t cover. Loose-fill material settles into every joist bay, creating a continuous thermal blanket that stops the sun-baked attic heat from bleeding into the rooms below. For most 91343 ranch homes, this is the fastest path from R-11 or R-19 up to R-38 or R-49, and the comfort change in west-facing bedrooms is immediate. We install blown-in insulation as a dedicated insulation contractor, using the right material for the job, whether that’s recycled cellulose, fiberglass, or mineral wool. See our full Blown In Insulation service details for more on material options.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the top of the ceiling joists, or you can see bare drywall in spots when you look across the attic floor.
What it costs in North Hills
Blown cellulose in North Hills typically runs $1.10 to $1.80 per square foot installed, depending on depth and whether old material needs removal first.
How we do it
We air seal penetrations, mark target depth, then blow GreenFiber cellulose to a uniform R-38 or R-49 across the attic floor in a single pass.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel 10 to 15 degrees warmer than the rest of the house on hot afternoons, and your AC runs almost continuously from mid-June on.
What it costs in North Hills
Blown-in attic insulation in North Hills generally lands between $1,800 and $3,200 for a typical 1,200 to 1,800 square foot ranch, including air sealing.
How we do it
We remove any failed or contaminated material, seal the attic floor penetrations, and blow loose-fill to a measured depth that meets or exceeds code for this climate.
Blown In Fiberglass Insulation
Signs you need it
The existing fiberglass batts have compressed, shifted, or been disturbed by rodents, leaving gaps around wiring, plumbing, and recessed lights.
What it costs in North Hills
Blown fiberglass in North Hills averages $1.20 to $1.90 per square foot installed, depending on target R-value and attic accessibility.
How we do it
We blow loose-fill fiberglass from brands like Owens Corning or Johns Manville across the attic floor, using depth markers to guarantee even coverage.
Loose Fill Insulation
Signs you need it
Your attic has irregular joist spacing, shallow eaves, or tight corners where batt installation would leave gaps and thermal bridging.
What it costs in North Hills
Loose fill insulation in North Hills typically falls between $1,500 and $2,800 for a complete attic, depending on square footage and access difficulty.
How we do it
We run a blower hose into the attic and fill every cavity to a uniform depth, targeting the R-value your home needs for the Valley’s cooling season.
What Blown In Insulation Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Cellulose insulation (installed) | $1.10 – $1.80 per sq ft |
| Fiberglass blown-in (installed) | $1.20 – $1.90 per sq ft |
| Full attic job (1,200 – 1,800 sq ft home) | $1,800 – $3,200 |
Does blown in insulation actually lower energy bills in North Hills?
Yes. In North Hills, where the cooling season runs from May through October, bringing attic insulation from R-11 to R-38 or higher cuts the heat gain that forces your AC to run constantly. Most homeowners notice lower bills within the first full summer. Call (877) 680-3557 for a specific estimate on your home.
Is cellulose or fiberglass better for a North Hills attic?
Both work, but cellulose often performs better in older Valley attics because it fills irregular cavities and resists airflow better than loose fiberglass. We carry both, and we’ll tell you which one fits your roof structure and budget. Call (877) 680-3557 and we’ll walk you through the actual tradeoffs for your home.
Brands We Service in North Hills
We stock and install insulation from eight major manufacturers, including GreenFiber cellulose, Owens Corning and Johns Manville fiberglass, and Knauf products. That means the right material for your North Hills attic gets ordered and installed without waiting on a supplier’s limited inventory. We keep the most common Valley jobs covered with local stock, so turnaround stays tight even during peak summer demand. See our brands for the full roster.

What pushes price up in North Hills is usually the condition of the existing attic: rodent contamination, collapsed material that needs removal, or very low-pitch roofs that make the work slow and physically difficult. Air sealing adds labor but pays for itself in reduced heat gain. We give you an upfront price before any work starts, and that number does not change mid-job unless you ask us to expand the scope.

— Miguel Flores"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nia Robinson"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
