Insulation Company in North Hollywood, CA
Blown in insulation is the most common call we get from North Hollywood homeowners, and the reason comes down to how this part of the Valley was built. Most of the housing stock went up between the 1940s and 1960s, when cheap energy made insulation an afterthought. Those original attics now carry either a thin layer of settled mineral wool or nothing at all. Meanwhile, summer attic temperatures in North Hollywood routinely hit 140 to 160°F. The result is a house that bakes from the top down, pushing your AC to run constantly. We only do insulation, which means we do it better.

Why North Hollywood Homes Are Different
North Hollywood’s housing stock was built for a climate that barely needs heating. The single-story stucco tract houses that dominate the neighborhoods east of Lankershim and north of Burbank Boulevard date mostly from the post-war years, when builders framed attics with minimal venting and skipped insulation entirely or dropped in a thin layer that has long since compacted. Stucco exteriors absorb the Valley sun all afternoon, and low-pitch or flat roofs leave very little attic air space for heat to escape. That combination means attic temperatures climb far above the outside air, and that heat radiates through ceilings into living spaces for hours after sunset. In the older stucco tracts around 91601 and 91606, we regularly find original attics with no baffles, no vent chutes, and wiring from the knob-and-tube or early Romex era that requires careful workmanship around junction boxes when blowing in new material. This is heat-defense work, not cold-weather insulation, and the approach has to match that from the first estimate.
Our Main North Hollywood Services
Two services account for most of what North Hollywood homeowners ask us about: attic insulation and spray foam. Each one addresses the same core problem – intense summer heat soaking through the ceiling – but they do it with different materials and different installation methods.
Attic Insulation in North Hollywood
Attic insulation is the highest-ROI upgrade for most North Hollywood homes because the attic is where the heat enters first. In the older stucco tracts around 91611 and 91612, we see attics with a thin layer of settled mineral wool that tests at R-8 or less, far below what the Valley climate demands. Adding the right material – batts, blown-in, or spray foam depending on the attic’s layout and venting – can drop upstairs temperatures by ten degrees or more in August. Flat and low-pitch roofs complicate the work because there is little space to maneuver, so we scope every job before quoting. Read the full breakdown at Attic Insulation in North Hollywood.

Spray Foam Insulation in North Hollywood
Spray foam earns its keep in North Hollywood on homes with flat roofs, enclosed rafter bays, and other spaces where traditional batts or blown-in material underperform. Closed-cell foam, which we install from the Demilec line, adds both thermal resistance and structural rigidity, making it a strong fit for the low-pitch roofs common across 91615 and 91616. Open-cell foam works well in vented attics where air sealing is the bigger priority. Spray foam is not a one-material answer for every home, and we will tell you when blown-in or batts make more sense for your budget. See Spray Foam Insulation in North Hollywood for the specifics.

Blown In Insulation in North Hollywood

Blown in insulation in North Hollywood is the workhorse fix for older attics, and it usually solves the exact problem these homes have: a wide attic floor with thin or missing coverage that lets 140°F attic air drive heat into the rooms below. Because so many of the original tract houses in 91611 and 91612 have low-pitch roofs, there is not much vertical attic space, and that means the blown-in job needs baffles and vent chutes installed before any material goes down. We install both fiberglass and cellulose blown-in material, and the right choice depends on your attic’s depth, your budget, and whether you want the recycled-content option that Blown In Insulation customers often ask about. The typical North Hollywood job takes one day, and most homeowners feel the difference the same afternoon.
Blown In Attic Insulation
Signs you need it
You need blown in attic insulation in North Hollywood if rooms feel hotter than the thermostat says, your AC runs long cycles in the afternoon, or you can see the tops of your ceiling joists because the existing layer has settled to nearly nothing.
What it costs in North Hollywood
Blown in attic insulation in North Hollywood typically runs $1.50 to $3.50 per square foot depending on the target R-value and whether old material has to be removed first.
How we do it
We seal bypasses around plumbing vents and wiring penetrations, install baffles and vent chutes to keep the soffit vents open, blow the material to the specified depth, and verify the coverage with a depth check before we pack up.
Blown In Cellulose Insulation
Signs you need it
Homeowners in North Hollywood choose blown in cellulose when they want a recycled-content material that slows air movement through the attic better than lighter fiberglass, especially in older homes with uneven joist spacing.
What it costs in North Hollywood
Blown in cellulose insulation in North Hollywood typically falls in the $1.75 to $3.00 per square foot range, with most whole-attic jobs landing between $1,800 and $3,500.
How we do it
We use the GreenFiber cellulose line, blowing it to the density that gives you the R-value we agreed on, and we hit the attic boundaries carefully so the material stays where it belongs instead of drifting into vents.
Blown In Fiberglass Insulation
Signs you need it
Fiberglass blown in insulation makes sense in North Hollywood when you want a lighter material that goes in faster and costs less upfront, particularly for large open attics over single-story stucco homes.
What it costs in North Hollywood
Blown in fiberglass in North Hollywood typically runs $1.50 to $3.50 per square foot, with a standard 1,200-square-foot attic landing between $1,800 and $4,200 depending on depth.
How we do it
We run the hose from the truck, blow the fiberglass in a controlled pattern, and level it so the R-value is consistent across the whole attic floor instead of thick in some spots and bare in others.

| Blown in fiberglass (per sq ft) | $1.50 – $3.50 |
Is blown in insulation worth it in a North Hollywood summer?
Yes. In North Hollywood, blown in insulation is one of the highest-ROI comfort upgrades because attic heat drives most of a home’s cooling load. Most customers notice cooler rooms within a day of installation. Call (877) 680-3557 for a specific number for your attic.
