Insulation Company in North Hollywood, CA
Blown in insulation is the workhorse retrofit for North Hollywood’s aging housing stock, and it’s the service we recommend most often here. Homes built between the 1940s and 1970s dominate this part of the San Fernando Valley, and most were framed with little more than a thin layer of original batting that has long since settled into near-uselessness. When summer temperatures push past 95°F and attics bake under relentless Valley sun, the difference between a properly insulated home and a mid-century original is the difference between a manageable A/C bill and a $600 August surprise. Brea Insulation has served North Hollywood since 2014. Call (866) 858-4033 for a free estimate.
Our specialization matters here because North Hollywood presents a very specific set of problems that generalist contractors routinely misdiagnose. We carry eight insulation brands, including CertainTeed, Icynene, and GreenFiber, so we can match the material to the actual condition of your attic or walls, not just to whatever is cheapest to stock. The right insulation for your home, not just what’s easiest to install.
Why North Hollywood Homes Are Different
North Hollywood sits squarely in the San Fernando Valley’s inland heat basin, where summer highs routinely exceed 95°F and the marine layer that cools coastal neighborhoods rarely makes it over the Cahuenga Pass. That means the insulation conversation here is dominated by heat gain, not winterizing. A North Hollywood attic in August can hit 140°F, and that heat doesn’t stay in the attic. It radiates down through ceilings into living spaces, forcing air conditioners to run continuously and still leave bedrooms stuffy by late afternoon. Proper attic insulation and air sealing is the single highest-ROI improvement a NoHo homeowner can make, and it’s where we start almost every assessment.
The housing stock compounds the problem. Most single-family homes in the 91601, 91602, 91605, and 91606 ZIP codes are post-war stucco bungalows and small duplexes built from the 1940s through the 1970s. Many of them went up before California’s Title 24 energy standards existed, which means wall cavities with zero insulation and attic spaces with a desultory two or three inches of fiberglass that has compressed to half that over six decades. Around the NoHo Arts District and the Red Line corridor, we see the same pattern repeated in older multifamily and rent-controlled apartment buildings, where flat or low-slope roofs leave little attic cavity and make wall insulation and roof-deck work more relevant. The recurring job is a 1950s stucco bungalow whose flat attic space turns into an oven by noon. Blown-in attic insulation, often paired with a radiant barrier, is the fix that changes comfort and cooling cost fastest.
One more local reality: pre-1978 drywall and plaster are common throughout North Hollywood, which means lead-safe work practices are a routine part of our retrofit jobs here. We plan for it, we do it properly, and it’s baked into how we approach every older home.
Our Main North Hollywood Services
Most North Hollywood homeowners reach out about one of two things: an attic that’s baking the house, or air leaks and thin insulation in walls and rim joists. These are the two services we’re called out for most often.
Attic Insulation in North Hollywood
Flat and low-slope roofs are common in the flats of North Hollywood, and they leave less room to work than a pitched roof in the hills. We’re used to tight, shallow attic cavities where access is through a small closet hatch and the working height is measured in inches, not feet. The job usually means removing or topping up settled fiberglass, air-sealing penetrations, and blowing in new material to R-38 or better. On a 1,200 square foot NoHo bungalow, the difference is noticeable within a day. Attic Insulation in North Hollywood covers the full scope and pricing.
Spray Foam Insulation in North Hollywood
For homes where the attic is used as living space, or where the roof deck needs insulating directly, spray foam is the method we recommend most. It’s also the right call for sealing rim joists and crawl spaces in the older wood-frame construction that defines North Hollywood’s housing stock. Closed-cell foam adds structural rigidity, which matters in a seismic market, and open-cell foam does an excellent job of deadening sound from nearby freeway traffic and the flight path. Spray Foam Insulation in North Hollywood explains what a typical North Hollywood spray foam project involves.

Blown In Insulation in North Hollywood
Blown in insulation is the most practical retrofit for the majority of North Hollywood homes built before 1980, where existing attic insulation is thin, settled, or missing entirely. In a San Fernando Valley summer, a poorly insulated attic can reach 140°F, and that heat radiates into the living space below, forcing air conditioners to work far harder than they should. Adding blown-in fiberglass or cellulose to R-38 or R-49 regularly drops attic temperatures by 30 degrees or more and takes serious pressure off the cooling system. We install blown in insulation using both fiberglass and GreenFiber cellulose, and the material choice depends on your attic’s condition, depth, and existing material. Learn more about the method itself on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the tops of the ceiling joists, or you can see bare drywall in spots where wind has drifted the old material away.
What it costs in North Hollywood
Blown-in cellulose for a typical 1,200 square foot North Hollywood attic runs $1,700 to $3,400 depending on depth and existing material removal.
How we do it
We remove any compromised material, air-seal penetrations, and blow GreenFiber cellulose to the specified depth using a calibrated machine, then check for even coverage with depth markers.
Blown In Attic Insulation
Signs you need it
Rooms farthest from the air handler stay warm all afternoon, or your A/C runs constantly from July through September and the upstairs or back bedrooms never really cool off.
What it costs in North Hollywood
Blown-in attic insulation in North Hollywood typically ranges from $1,900 to $3,000 for a standard single-story bungalow when it includes removing old, settled material.
How we do it
We set up protection around the access point, run a hose to the attic, and blow fiberglass or cellulose in measured passes until depth markers confirm R-38 or R-49 coverage across the full floor.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are compressed, discolored, or only a few inches thick, and you want a material that won’t settle as much over time.
What it costs in North Hollywood
Blown-in fiberglass for a North Hollywood attic runs $1,600 to $3,200, with the final figure set by square footage and target R-value.
How we do it
We blow loose-fill fiberglass to an even, consistent depth using a dedicated machine, covering the entire attic floor including the hard-to-reach perimeter and corners.
Loose Fill Insulation
Signs you need it
You can see gaps, bare spots, or thin patches across your attic floor, especially around the eaves and in corners where the original installer couldn’t reach.
What it costs in North Hollywood
Loose fill insulation for a typical North Hollywood attic is priced between $1,500 and $3,000, depending on material type and depth.
How we do it
We assess the existing depth, note any uneven areas, and blow loose fill to a consistent height across every inch of the attic floor, including over the top plates of interior walls.
What Blown In Insulation Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Blown-in attic insulation, 1,200 sq ft | $1,900 – $3,000 |
| Blown-in cellulose top-up | $1,100 – $1,800 |
| Blown-in fiberglass, full attic | $1,600 – $3,200 |
Prices in North Hollywood run at the middle of the regional range, mostly because attic access in older bungalows is tight and material removal adds labor. Call (866) 858-4033 for an exact quote. Estimates are free.
Can you blow insulation over existing insulation?
Yes, in most North Hollywood attics we can blow new material directly over settled insulation if it’s dry and not moldy. We check condition first, and if the old material is compromised, removal is the cleaner path.
How long does blown in insulation last in the Valley heat?
Quality blown-in fiberglass or cellulose will perform for decades, but high Valley heat accelerates settling in any loose fill material over time. A 20-year-old attic here generally needs a top-up to restore its original R-value.
Brands We Service in North Hollywood
We stock and install material from eight manufacturers so the product matches the job, not the other way around. Our North Hollywood work most often calls for CertainTeed fiberglass, GreenFiber cellulose, and Icynene or Demilec spray foam when air sealing is the priority. Local parts availability means most projects are scheduled within the same week as the estimate. See our brands for the full lineup.

What pushes the price higher in North Hollywood is access. Tight flat-roof attic cavities take longer to work in, and pre-1978 homes require lead-safe containment on any wall or ceiling work. You’ll get an upfront price before we start, and that number doesn’t move unless you change the scope.
