Insulation Company in Tujunga, CA
Blown in insulation is the most common retrofit we perform in Tujunga, and for good reason: most of the homes here were built between the 1940s and 1960s with no insulation at all, or with a thin layer that has settled into near uselessness over six decades of foothill heat. The sun-baked Verdugo foothills push attic temperatures well past 140 degrees in summer, while clear winter nights drop near freezing, and that swing is exactly what blown in insulation is built to handle. If you’re in ZIP 91042 or 91043 and your upstairs rooms or rear bedrooms run ten degrees hotter than the rest of the house, the attic is usually the culprit. Call Thermal Insulation Co at (855) 382-3451 and we’ll tell you what’s actually up there.
Why Tujunga Homes Are Different
Tujunga doesn’t insulate like the LA basin floor. The homes here sit against the Angeles National Forest boundary, ranging from flatland ranchers off Foothill Boulevard up into hillside streets where the lots climb and the canyons funnel wind. Summer heat in Tujunga regularly runs eight to twelve degrees hotter than Burbank or Glendale on the same day, and Santa Ana winds drive hot, dry air through the canyons from late September into November. That means an attic that measures 100 degrees in the valley can hit 140 here, and your insulation package has to be sized for that reality, not for a generic Southern California average.
Most of Tujunga’s housing stock is single-story stucco bungalows and ranch homes from the 1940s through 1960s, many with vented attics and original framing. These houses predate California’s Title 24 insulation mandates by decades. A large share still have barely anything above the ceiling: bare rafters, maybe a quarter-inch of settled fiberglass batts somebody threw in during the 1980s. Add in the foothill terrain, where technicians routinely find attic vents packed with wind-blown leaf litter and rodent nesting that has compressed whatever insulation existed, and the work here often means removal and full replacement rather than a simple top-off. The climate, the age of the homes, and the proximity to wildfire country all change the material conversation in ways flatland contractors don’t have to think about.
Our Main Tujunga Services
Two services generate most of the calls we get from Tujunga homeowners: attic insulation retrofits and spray foam applications. Here’s what each one actually involves in this city.
Attic Insulation in Tujunga
Attic insulation is where most Tujunga homes are losing the battle against foothill heat and cold winter nights. The work typically starts with removing old, contaminated material, air sealing the ceiling plane, and installing batts or blown-in insulation to a level that actually matches this climate. In older Tujunga bungalows, we frequently find that bathroom exhaust fans vent directly into the attic rather than through the roof, which means the insulation job has to include correcting that before anything gets installed. Attic Insulation in Tujunga covers the specifics of what we check and what we install.
Spray Foam Insulation in Tujunga
Spray foam earns its keep in Tujunga’s hillside and canyon-adjacent homes, where air leakage through irregular framing and hard-to-reach attic transitions is the bigger problem than conduction through the ceiling. Open-cell foam also seals those wind-driven gaps that Santa Ana events exploit. For homes near the wildfire boundary, we talk through material choices carefully, since closed-cell foam’s air-sealing properties have to be weighed alongside the ember-resistance conversation that every foothill homeowner should be having. Spray Foam Insulation in Tujunga explains both foam types and where each makes sense here.

Blown In Insulation in Tujunga
Blown in insulation is the fastest, least invasive way to bring a 1950s Tujunga rancher up to modern thermal performance, because loose-fill material flows around existing wiring, blocking, and uneven framing in ways batts can’t match. In Tujunga specifically, where homes were built long before Title 24 and many attics still have bare rafters or a compressed half-inch of old fiberglass, blown in loose-fill gets R-value into every corner without gutting the ceiling. We install brand-name fiberglass and recycled cellulose systems depending on the home and the attic conditions. For more on the method itself, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has old, settled insulation that measures less than 3 inches deep, or you can see bare drywall between ceiling joists from the attic hatch.
What it costs in Tujunga
Blown-in cellulose in Tujunga typically runs $1.60 to $2.80 per square foot installed, depending on depth and removal needs.
How we do it
We remove contaminated material if needed, air seal penetrations, and blow GreenFiber cellulose to the specified R-value with a calibrated machine.
Blown In Attic Insulation
Signs you need it
Rooms at the back of the house run noticeably hotter in summer and colder in winter than rooms near the thermostat, and the attic feels like an oven during the day.
What it costs in Tujunga
Blown-in attic insulation jobs in Tujunga generally fall between $2,200 and $4,800 for a typical 1,200 to 1,800 square foot single-story home.
How we do it
We clear vents and eaves, seal the ceiling plane, mark depth gauges, and blow loose-fill to a uniform depth that meets California energy code levels for attic applications.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are torn, compressed by foot traffic, or stained from roof leaks, and no longer hold their rated R-value.
What it costs in Tujunga
Blown-in fiberglass in Tujunga typically costs $1.40 to $2.50 per square foot installed, with removal of old material priced separately.
How we do it
We remove the failed material, inspect for wiring issues common in 1940s and 1950s Tujunga homes, then blow Owens Corning or Johns Manville loose-fill to the target depth.
Loose Fill Insulation
Signs you need it
Your attic has open cavities, uneven joist spacing, or low-clearance areas where batt installation would leave gaps and voids.
What it costs in Tujunga
Loose fill insulation in Tujunga runs $1.40 to $2.80 per square foot installed, excluding any structural work or vent repairs.
How we do it
We install loose-fill material using a high-output blower, working around existing framing and electrical to achieve a continuous thermal blanket with no voids.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown-in fiberglass (per sq ft installed) | $1.40 – $2.50 |
| Blown-in cellulose (per sq ft installed) | $1.60 – $2.80 |
| Typical 1,200 – 1,800 sq ft attic job | $2,200 – $4,800 |
Older Tujunga homes with knob-and-tube wiring or rodent-contaminated insulation push costs toward the upper end, because the wiring has to be evaluated before we bury it in loose-fill, and full removal adds labor and disposal fees. We quote upfront and the number we give you is the number on the invoice.
How long does blown in insulation take in Tujunga?
Most Tujunga attics are done in one day. Larger homes or jobs requiring full removal of old material, rewiring work, or vent repairs may take a second day.
Can blown in insulation be installed over old insulation in Tujunga?
Sometimes, but not often in Tujunga. The wind-blown debris and rodent nesting we find in foothill attics usually means the old material has to come out first. Call (855) 382-3451 and we’ll tell you what you’re working with.

FAQs About Insulation Company in Tujunga
Insulation replacement in an existing attic does not require a building permit in Los Angeles County when it doesn’t involve structural changes or electrical work. If we find wiring issues that need correction, those repairs fall under separate permitting, and we’ll tell you before anything happens.
Estimates are typically scheduled within one to two business days. Start dates usually land within a week of contract, and most blown-in attic jobs are completed in a single day.
We’ll look at the wiring before we install anything. Knob-and-tube is common in 1940s Tujunga homes, and loose-fill insulation can’t simply be blown over active knob-and-tube circuits. If the wiring is live, those circuits need to be addressed by a licensed electrician before insulation covers them. Call (855) 382-3451 and we’ll walk you through what your home needs.
