Insulation Company in North Hollywood, CA
Blown in insulation is the workhorse retrofit for North Hollywood’s older housing stock. Most homes in the 91601, 91602, 91605, and 91606 ZIP codes were built between the 1920s and 1950s with zero wall insulation and a thin layer of whatever was cheap in the attic. That means we spend most of our days in North Hollywood drilling small access holes in stucco and blowing cellulose or fiberglass into wall cavities that have been empty for 70 years. The payoff is immediate once Valley summer hits and the west-facing walls stop radiating heat into the living room. Call us at (844) 241-0737 to talk through what your house actually needs.
Why North Hollywood Homes Are Different
North Hollywood’s housing stock has a very specific profile. The neighborhoods around the NoHo Arts District, Valley Village, and the Orange Line corridor are packed with 1920s and 1930s stucco bungalows and postwar tract houses. Walk through any block in 91601 or 91606 and you’ll see Spanish-style homes with thick stucco walls and almost no insulation behind them. The attics are shallow, often with limited headroom, which changes how we approach blown-in work. The garden-style apartment buildings that fill the streets between Burbank Boulevard and Victory Boulevard are even worse: many have never had an attic upgrade since they were built, and landlords are often looking for the most cost-effective way to satisfy Title 24 energy requirements.
The San Fernando Valley climate is a huge factor. Summer temperatures routinely spike past 100°F, and those west-facing walls absorb sun all afternoon. Winter nights dip into the 40s. The swing means insulation work here pays for itself faster than in coastal ZIP codes. One more North Hollywood quirk: knob-and-tube wiring is still common in these old homes, and we regularly have to coordinate with electricians before blowing insulation into walls that contain live knob-and-tube circuits. That’s not a problem we create; it’s one we flag early so you’re not surprised.
Our Main North Hollywood Services
Most North Hollywood homeowners start with one of two conversations: fixing an under-insulated attic, or sealing air leaks with spray foam. Both jobs play a big role in how comfortable these older Valley homes feel year-round.
Attic Insulation in North Hollywood
North Hollywood attics are often the single biggest energy leak in the house. In a 1940s bungalow near the NoHo Arts District, the attic might have two inches of rock wool from the Eisenhower era, which is effectively nothing by today’s standards. We remove what’s failing, air-seal the penetrations where heat escapes, and blow in fresh insulation matched to the attic’s depth and access. For homes with west-facing exposure and shallow attics, a radiant barrier can also cut heat gain meaningfully. This is the highest-ROI job for most North Hollywood homeowners because the sun here punishes roofs for six months a year. Attic Insulation in North Hollywood is covered in detail on its own page.
Spray Foam Insulation in North Hollywood
Spray foam earns its keep in North Hollywood wherever air leaks are the real problem: rim joists in raised foundations, cantilevered floors, the underside of attic rooflines in bonus rooms, and the gaps around old wall penetrations. In a 1930s bungalow with balloon framing, air moves freely between the crawl space and the attic, and spray foam is the cleanest way to stop that chimney effect. Closed-cell foam also gives older stucco homes some structural rigidity, which matters in a seismic zone. We install Icynene open- and closed-cell systems, and we’ll tell you honestly when foam is the wrong move for the budget. Spray Foam Insulation in North Hollywood explains the material choices and what a typical job involves.

Blown In Insulation in North Hollywood
Blown in insulation is the most practical retrofit for North Hollywood’s older homes, and it’s the service we recommend most often when walls are empty and attics are under-insulated. A 1920s bungalow in 91606 or a garden apartment off Magnolia Boulevard can go from zero wall insulation to a sealed, comfortable envelope without tearing out drywall. The material fills the odd-sized cavities, settles into place, and starts cutting the summer heat load immediately. For homes with shallow attics or walls that can’t be opened up, Blown In Insulation is the right fit, and we use Knauf fiberglass and GreenFiber cellulose depending on the cavity and the budget.
Cellulose Insulation
Signs you need it
Your walls are cold to the touch in winter, your energy bills climb every August, and the house was built before 1960 with no wall insulation.
What it costs in North Hollywood
Blown-in cellulose for walls and attics in North Hollywood typically runs $1.10 to $2.15 per square foot of treated area, depending on depth and access.
How we do it
We drill small access holes at each stud bay or use the attic hatch, blow the cellulose to the target depth with specialized equipment, and patch every access point cleanly.
Blown In Attic Insulation
Signs you need it
The upstairs rooms bake in summer, the attic floor is barely covered with old material, and you can feel heat radiating from the ceiling after sunset.
What it costs in North Hollywood
Attic-only blown-in jobs in North Hollywood typically range $1.45 to $2.85 per square foot, with shallow-access attics and old-material removal pushing the number higher.
How we do it
We air-seal the attic floor penetrations first, then blow new insulation to the R-value that matches your home’s age and roofline, leaving the attic properly vented.
Blown In Fiberglass Insulation
Signs you need it
You want an affordable, non-settling option for a deep attic and prefer fiberglass over cellulose for its moisture tolerance and stable R-value.
What it costs in North Hollywood
Blown-in fiberglass for North Hollywood attics typically runs $0.90 to $2.05 per square foot, with deep-blow attic jobs and high R-values affecting the total.
How we do it
We lay down the correct depth of Knauf loose-fill fiberglass with a calibrated blower, monitor coverage area by area, and verify the final depth matches the R-value target.
Loose Fill Insulation
Signs you need it
Your attic has awkward corners, shallow joist bays, or areas the old batts never covered, and you want complete coverage without framing gaps.
What it costs in North Hollywood
Loose fill projects in North Hollywood, including walls and attics, typically range $1.10 to $2.35 per square foot for the full job.
How we do it
We inspect the cavity layout first, fill every bay completely with the loose-fill material that suits the space, and match the depth to the insulation level the home actually needs.

Is blown in insulation worth it in an older North Hollywood home?
Almost always, yes. Empty walls and thin attic coverage in a 1940s stucco home mean you’re paying to cool the Valley’s August heat. Blown-in insulation works without gutting the walls, which is why it’s the standard retrofit here. Call (844) 241-0737 for a free estimate on your home’s specific layout.
Do you need to rewire before blowing insulation into walls?
If your North Hollywood bungalow still has knob-and-tube wiring, yes. Insulation can’t cover live knob-and-tube, so we’ll help you coordinate that inspection before we touch the walls. Most 91601 and 91606 homes have already been rewired, but we always check.
