Insulation Company in Tujunga, CA
Blown in insulation solves the biggest comfort problem in Tujunga homes: attic heat that turns rooms facing the Verdugos into ovens by 2 p.m. Most houses here were built between the 1940s and 1970s, and the original attic insulation in many of them has compacted to a fraction of its rated R-value. We install blown in fiberglass and cellulose across the 91042 and 91043 ZIP codes, and we work around low-pitch roofs and tight attic clearances that make batts a poor fit.

Why Tujunga Homes Are Different
Tujunga sits in a sun-baked foothill canyon at the base of the Verdugos and San Gabriels, and the heat profile is different from what you find ten miles south in Glendale or Burbank. Summer afternoons routinely run 10 to 15 degrees hotter here because the canyon slopes absorb solar radiation and radiate it back into the housing stock well into the evening. The homes along Foothill Boulevard and the canyon-side streets are mostly mid-century single-story ranch and stucco builds, many with low-pitch or flat roofs and minimal original attic insulation. Scattered older cabins and newer rebuilds in the hills add to the mix, and a lot of them had insulation decisions made decades ago when nobody thought about air sealing.
There’s another layer here that flat, coastal, and non-wildland-urban-interface parts of LA simply don’t face. Tujunga is a Chapter 7A fire zone, which means attic and crawlspace insulation choices are both an energy decision and a fire-safety decision. Ember-resistant assemblies, mineral wool options, and proper venting all carry more weight when a red-flag wind event can push embers into attic vents. We factor that into every material recommendation we make in this community. The heat load drives attic upgrades hard, but the WUI fire code shapes how we approach the work.
On the practical side, homes on the canyon slopes and along the Sunland-Tujunga border often have poorly vented, low-clearance attics that trap heat and reach extreme temperatures. Before any new insulation goes down, our technicians routinely find degraded, compacted or rodent-damaged fiberglass and old knob-and-tube-era cavities. That existing condition changes the job scope, and it’s why we inspect before we quote.
Our Main Tujunga Services
Tujunga homeowners call us most about two problems: attics that cook the house all summer, and air leaks that make winter nights feel colder than the thermostat says. Here’s how both services work in this specific community.
Attic Insulation in Tujunga
Attic work in Tujunga usually means pulling out old, compacted material and starting fresh. Many of the mid-century ranches here have original insulation that has settled to R-9 or R-11 when the ceiling needs R-38 or higher for this climate. We address the heat load directly by air sealing the attic floor first, then blowing new material to the depth your roof assembly needs. In the hillside homes with low-clearance attics, we work with the space available rather than forcing a solution that won’t fit. Attic Insulation in Tujunga covers the full scope of what this job involves.
Spray Foam Insulation in Tujunga
Spray foam makes sense in Tujunga when the attic gets converted to living space, when the roof deck needs an air barrier, or when a crawlspace is wide open to the canyon air. Closed-cell foam from Icynene or Demilec creates an air barrier and a thermal barrier in a single application, which matters in a fire zone where gaps and voids are the enemy. It’s a more technical installation than blown in material, and it’s not the right answer for every roof assembly here. Spray Foam Insulation in Tujunga explains when it fits and when it doesn’t.

Blown In Insulation in Tujunga
Blown in insulation is the most common upgrade we install in Tujunga because it works with the housing stock, not against it. The mid-century ranches and canyon-side homes here have attics with irregular joist spacing, low clearances, and existing material that needs to come out first. Blown in fiberglass or cellulose fills the cavity completely, covers the thermal bypasses that batts leave open, and gets the attic to the R-value this foothill climate demands. For a deeper look at the method itself, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the joists, or you can feel heat radiating through the ceiling on summer afternoons.
What it costs in Tujunga
Blown in cellulose for a typical Tujunga attic runs $1.20 to $2.20 per square foot installed, depending on depth and access.
How we do it
We remove the old material, air seal the attic floor, and blow GreenFiber cellulose to the specified depth at the target density.
Blown In Attic Insulation
Signs you need it
Rooms on the south and west sides of the house run 8 to 12 degrees warmer than the rest of the home, or your cooling bills climb every summer.
What it costs in Tujunga
Standard blown in attic insulation here ranges from $1.00 to $3.50 per square foot, with the higher end covering removal and deeper coverage.
How we do it
We inspect the attic, remove compromised material, seal penetrations, and blow the new insulation to a uniform depth across the full attic floor.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are compressed, rodent-damaged, or scattered, leaving bare spots across the attic floor.

Blown in fiberglass runs $0.80 to $1.80 per square foot for material and labor, with attic prep work priced separately.
How we do it
We remove the degraded batts, identify air leaks, and blow Owens Corning or Johns Manville fiberglass to the depth your ceiling needs.

Signs you need it
Your attic has shallow or uneven coverage, or you’re adding insulation over an existing layer that’s still in acceptable condition.
What it costs in Tujunga
Loose fill insulation work in Tujunga falls between $0.80 and $2.20 per square foot, with access and cavity prep affecting the final number.
How we do it
We map the attic floor, prep the cavities, and blow the loose fill material to a consistent depth with no gaps or thin spots.

Can you blow insulation over old material in a Tujunga attic?
Sometimes, but only after an inspection. If the existing layer is dry, uncontaminated, and not compressed, we can blow over it. Most Tujunga attics we see have rodent damage or settled material that needs removal first.

Yes, when installed at the right depth and paired with air sealing. We target R-38 to R-49 for attic floors in this climate. Call (866) 393-6041 and we’ll measure what you currently have and quote the difference.

Most estimates happen within one to three business days. Installation scheduling depends on the scope, but standard blown in attic jobs are often finished in a single day once materials are on site. Call (866) 393-6041 and we’ll give you a real date, not a window.
Most re-insulation and air sealing work falls under standard building code and doesn’t require a separate permit. If your home is in a Chapter 7A WUI zone and you’re changing venting or roof assembly details, we’ll tell you exactly what the city requires before work starts.
Yes. Low-pitch roofs and tight attics are the norm along the canyon slopes here, not the exception. We use blowing equipment that works in confined access, and we map the attic before quoting so you know the plan fits your roof, not just a generic template.
