Insulation Company in Tujunga, CA
Blown in insulation is the most common fix we install in Tujunga, and for good reason: the canyon-edge temperature swings here expose every gap in an older home’s thermal envelope. Most houses in the 91042 and 91043 ZIP codes were built between the 1940s and 1960s with minimal attic coverage, which means heat pours in during afternoon sun and escapes fast after dark. We only do insulation, so when we assess a Tujunga home, we’re looking at the whole assembly: attic depth, wall cavities, air leaks, and the ember-resistant venting that became standard after the 2008 Sayre Fire. Call (877) 680-3557 and we’ll tell you exactly what your house needs and why.
Why Tujunga Homes Are Different
Tujunga sits tight against the San Gabriel Mountains, and the local climate does things you won’t see down in the LA basin. Day-to-night temperature swings of 30 to 40 degrees are normal here, especially in the summer. A house that hits 95°F by 3 p.m. can drop into the low 60s before midnight. Insulation in Tujunga has to work in both directions: slowing daytime heat gain and holding heat in once the canyon air cools off. That’s a different performance profile than a coastal home, and it’s why the material choice matters more than most people expect.
The housing stock adds another layer. Much of Tujunga is mid-century ranch and post-and-beam construction from the 1940s through the 1960s. These homes often have 2×4 or irregular framing, shallow attic cavities, and original insulation that has compressed to a fraction of its rated R-value. Then there’s the post-2008 Sayre Fire rebuilds, which were built to Chapter 7A wildfire standards. Those homes need insulation that integrates with ember-resistant vents and fire-rated assemblies, not whatever batt fits the stud bay. Any contractor who treats Tujunga like a generic LA suburb will get the details wrong.
Santa Ana winds complicate the picture further. Wind-driven dust and embers find their way into attic spaces through gaps that don’t matter much in calm weather. Proper air sealing is part of the insulation job here, not an add-on. Without it, you’re paying to condition air that leaks straight through the ceiling plane.
Our Main Tujunga Services
Most Tujunga homeowners call us about two things: getting their attic up to a proper R-value and air-sealing the whole envelope with spray foam. Here’s what each one looks like in this specific part of the foothills.
Attic Insulation in Tujunga
Attic work in Tujunga usually starts with removing compressed or rodent-damaged material from a 1960s ranch, then rebuilding the thermal barrier to a level that actually handles the canyon temperature swings. We check the existing venting against Chapter 7A requirements where fire rebuilds are involved, then match the right material to the framing. Fiberglass batts, blown-in cellulose, or mineral wool each make sense in different Tujunga attics. The full breakdown of how we handle attic jobs in this area is on our Attic Insulation in Tujunga page.
Spray Foam Insulation in Tujunga
Spray foam earns its keep in Tujunga’s post-and-beam homes because it air-seals and insulates in one pass. That matters when Santa Ana winds push dust and embers against the roofline. Open-cell Icynene handles interior walls and ceilings with sound control, while closed-cell Demilec gives the higher R-value per inch that shallow rafter bays often demand. We carry both, so the recommendation comes down to your framing and fire-rating needs, not what’s on the truck. Details are on our Spray Foam Insulation in Tujunga page.

Blown In Insulation in Tujunga
Blown in insulation is the workhorse retrofit for Tujunga’s older homes because it reaches the spots batts can’t: irregular stud bays, shallow attics, and the gaps around post-and-beam connections that let canyon air pour through. A 1950s ranch with 6 inches of settled cellulose in the attic is losing heat every night and gaining it every afternoon. Blowing in a fresh layer of Blown In Insulation over the top typically brings that attic from an effective R-11 up to R-38 or better, and the difference shows up on the first hot week. We run the hose into walls too, filling closed cavities that would otherwise require opening drywall.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, or you can feel temperature differences between rooms on hot afternoons.
What it costs in Tujunga
Blown-in cellulose for a typical Tujunga attic typically runs $1,800 to $3,200 depending on square footage and the depth of material already in place.
How we do it
We air-seal the attic floor penetrations first, then blow GreenFiber cellulose to the specified depth and density, checking coverage at the eaves and around vent openings.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel 10 degrees hotter than the rest of the house by mid-afternoon, or your AC runs constantly without hitting the set temperature.
What it costs in Tujunga
Blown in attic insulation runs $2,500 to $4,500 for the average Tujunga home, including removal of old material where needed.
How we do it
Our crew removes any compressed or contaminated material, air-seals the ceiling plane, installs baffles at the eaves to protect venting, then blows insulation to the R-value we agreed on.
Loose Fill Insulation
Signs you need it
You have open wall cavities from a remodel, or an older home with empty stud bays that let heat and cold pass straight through the drywall.
What it costs in Tujunga
Dense-packed loose fill into existing walls costs $2,000 to $3,800 in Tujunga, depending on how many linear feet of wall we’re filling and the access points available.
How we do it
We locate each stud bay, drill small access points, and dense-pack the cavity under pressure so the material fills completely without settling later.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown-in attic insulation (full job) | $2,500 – $4,500 |
| Blown-in cellulose attic | $1,800 – $3,200 |
| Dense-packed loose fill in existing walls | $2,000 – $3,800 |
How long does blown in insulation last in Tujunga?
Blown in fiberglass can hold its R-value for decades if it stays dry, while cellulose will settle some in the first year, so we over-blow slightly to compensate. Call (877) 680-3557 for a Tujunga-specific assessment of your attic.
Is blown in insulation better than batts for older Tujunga homes?
Usually yes, because older framing has irregular cavities that batts can’t fill completely, leaving air channels. Blown in material conforms to every gap and provides continuous coverage. Call (877) 680-3557 and we’ll tell you which one fits your specific framing.
Brands We Service in Tujunga
We stock and install Owens Corning, Johns Manville, and Rockwool products for Tujunga jobs, with material staged locally for faster turnarounds. We also carry Knauf batts and boards for specialized fire-rated assemblies we see on Chapter 7A rebuilds.

What Tujunga Customers Say
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— 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."
— Mark Schaefer
