Insulation Company in Tujunga, CA
Blown in insulation is the most common retrofit we perform in Tujunga, where 1940s and 1960s stucco bungalows were built with thin or settled attic batts never meant to hold back 100°F canyon heat. We’re Placentia Insulation, and we’ve served Tujunga since 2018 as a dedicated insulation contractor, not a generalist. The attic floors here tell a consistent story: original fiberglass batts compressed flat, R-values far below today’s code, and rooms that swing from hot to cold by the hour. Call (855) 773-6429 for a free estimate on blown in, attic, or spray foam work.
Why Tujunga Homes Are Different
Most Tujunga homes sit in direct path of the San Gabriel Mountain downslope winds that drive summer heat straight into attics. A July afternoon can push attic temperatures 30 to 40 degrees above the valley floor, and that heat bleeds through old ceilings for hours after sunset. The housing stock compounds the problem: single-story stucco bungalows and ranch homes from the 1940s through 1960s, almost all with original construction that predates modern insulation codes. We regularly find R-11 or R-13 batts in attics that need R-38 or better in this climate.
Hillside streets up toward the Angeles National Forest add another wrinkle. Blown-in insulation settles toward the downhill side over time, leaving the uphill ceiling edge as the coldest spot in winter and the hottest in summer. That pattern is so consistent in Tujunga that we check it on every hillside estimate. Flat, sun-baked lots in the 91042 and 91043 ZIP codes face a different issue: decades of radiant heat soaking the same attic all day, every day. Neither problem gets fixed with a one-size-fits-all material choice, which is why we match the product to the specific house and lot orientation.
Our Main Tujunga Services
Tujunga homeowners tend to call about two things: attics that need more insulation than the original batts provide, and spray foam for hard-to-reach areas where air sealing matters as much as R-value. Here’s how each works in this market.
Attic Insulation in Tujunga
Attic work in Tujunga almost always means removing or augmenting what’s already up there rather than insulating a blank space. The original fiberglass in a 1950s ranch home has typically settled to half its labeled R-value, and adding loose fill on top without addressing air leaks just buries the problem. We assess the existing batts, check for the uneven settling common on hillside lots, and recommend the right material and depth for the specific roof pitch and orientation. For the full breakdown of what attic insulation involves here, see Attic Insulation in Tujunga.
Spray Foam Insulation in Tujunga
Spray foam earns its keep in Tujunga where framed walls, cantilevered floors, and kneewall attics leak air and defeat standard batt installation. Closed-cell foam from Demilec or Icynene adds structural rigidity and a vapor barrier in one pass, which matters on hillside homes where crawlspace moisture rides uphill during winter rains. Open-cell foam suits interior sound control and tight cavity work. We carry both chemistries so the application drives the choice, not the other way around. Details are on the Spray Foam Insulation in Tujunga page.

Blown In Insulation in Tujunga
Blown in insulation solves the core Tujunga problem: attics with settled or thin original batts that let canyon heat pour through the ceiling. We blow loose fill over and around what’s already there, building R-value to the level this climate actually demands. Blown In Insulation is the fastest way to bring a 1950s or 1960s attic up to modern performance without tearing out the ceiling. On hillside homes, we compensate for the downhill settling pattern with extra material on the uphill edge, so the whole ceiling plane holds a consistent temperature year round.
Cellulose Insulation
Signs you need it
Rooms that heat up within an hour of sunrise and stay hot past midnight, plus ceiling drywall that feels warm to the touch in summer, are the classic signs your attic needs more insulation than settled batts provide.
What it costs in Tujunga
Blown in cellulose in a Tujunga attic typically runs $1.10 to $1.40 per square foot, or $1,100 to $1,900 for a standard 1,000 to 1,400 square foot attic, depending on depth and access.
How we do it
We air-seal penetrations, mark target depth, and blow GreenFiber cellulose to an even R-38 or R-49 layer in a single pass, then recheck the coverage with a thermal camera before we pack up.
Blown In Attic Insulation
Signs you need it
If your original fiberglass batts measure under 6 inches deep or show dark dust lines where air has been filtering through, the attic has been underperforming for decades and needs blown in coverage.
What it costs in Tujunga
Blown in attic insulation in Tujunga generally lands between $1,100 and $2,800 for a full attic, with hillside homes on the higher end because we add extra material to the uphill side to counter settling.
How we do it
We remove or reposition any blocking vents, run the hose from the truck up through the access point, and build the loose fill to specified depth, checking density in four corners of the attic before the final pass.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown in cellulose (full attic) | $1,100 – $1,900 |
| Blown in fiberglass (full attic) | $1,200 – $2,800 |
| Loose fill over existing batts | $1,100 – $2,400 |
Is blown in insulation worth it in Tujunga’s heat?
Yes. A correctly insulated attic drops ceiling surface temperatures by 20 to 30 degrees in summer, and the savings on cooling show up on the first full billing cycle after installation.
How long does blown in insulation take in Tujunga?
Most Tujunga attics take one full day from setup to cleanup. Two-story or hillside homes with difficult access can stretch into a second morning, but we schedule the work around your availability.

What Tujunga Customers Say
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Adriana Rodriguez"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Gilbert Ramirez"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
