Insulation Company in Tujunga, CA
Most Tujunga homes need more insulation than they have, and the fix usually starts with blown in insulation in the attic. Houses here were built between the 1940s and 1960s, long before California’s energy codes required serious thermal protection, and the foothill climate punishes that gap: 100°F afternoons in summer, near-freezing mornings in winter, and a 30-degree swing between them most days. We install blown in insulation, attic insulation, and spray foam, and we choose the material based on what each Tujunga house actually needs. Call (844) 241-0737 for a free estimate.
Why Tujunga Homes Are Different
Tujunga sits at the base of the San Gabriel Mountains, and its older housing stock reflects the era it was built in. Many homes in the 91042 and 91043 ZIP codes are ranch-style or cabin-like wood-frame structures from the 1940s through 1960s. We regularly open up these attics and find a few inches of settled fiberglass, or nothing at all. It’s not neglect, it’s just how mid-century builders worked. Insulation was an afterthought, and in a climate where summer heat loads an attic to 130°F or more, that afterthought becomes the biggest single driver of discomfort and high cooling bills.
The canyon-adjacent streets add another layer. Homes along roads winding up from Foothill Boulevard often have attics with minimal ventilation, which means heat builds up and stays there. That trapped heat degrades whatever insulation exists, compresses it, and makes it perform worse year after year. We check for that on every Tujunga job. Many of these older houses also lack proper vapor barriers, which matters in a climate where winter mornings near freezing and daytime temps climb into the 60s. Without a vapor barrier, warm indoor air condenses inside wall cavities and attics, wetting the insulation and inviting mold. The flatland suburbs don’t deal with this combination nearly as often, which is why a Tujunga-specific approach matters.
What does that mean in practice? It means blown in insulation and spray foam get specified more often here than in, say, a 1990s tract home in the Valley floor. It means we look at the attic ventilation before we add insulation, because adding R-value to a poorly vented Tujunga attic just bakes the new material. And it means we pay attention to the pier-and-beam foundations common in the foothills, because air moves up through those crawl spaces and into the living areas, undoing the work done upstairs. Sealing the envelope in Tujunga is a whole-house exercise, not a one-product fix.
Our Main Tujunga Services
Tujunga homeowners call us most about two services: attic insulation for older homes losing conditioned air through the ceiling, and spray foam for the harder-to-reach areas where air leaks are worst. Both solve the same underlying problem, just with different materials and methods.
Attic Insulation in Tujunga
Attic insulation is the highest-impact upgrade for most Tujunga homes, especially the 1940s and 1950s ranch houses where the original insulation has settled to an inch or less. In a foothill climate where attic temperatures swing 50 degrees or more daily, a properly insulated attic keeps the house measurably cooler in summer and warmer on winter mornings. We use Owens Corning, Johns Manville, CertainTeed, and Knauf fiberglass, Rockwool mineral wool, or GreenFiber cellulose depending on what the attic conditions call for. The work typically includes air sealing around penetrations, checking ventilation, and bringing the attic to current recommended R-values. Learn more about Attic Insulation in Tujunga.
Spray Foam Insulation in Tujunga
Spray foam does what batts and blown-in materials cannot: it air-seals and insulates in one pass. That matters in Tujunga homes with pier-and-beam foundations, where air moves up from the crawl space through rim joists and wall cavities. It also matters for the cabin-like houses on hillside lots, where odd framing angles and inaccessible cavities make traditional insulation a poor fit. We install open-cell and closed-cell foam through Icynene and Demilec, two of the most specified spray foam brands in the performance-building world. The result is a tighter envelope and a house that stops leaking conditioned air. Read about Spray Foam Insulation in Tujunga.

Blown In Insulation in Tujunga
Blown in insulation is the most common service we perform in Tujunga, and the reason is simple: it is the fastest, most cost-effective way to add serious R-value to the attics of mid-century foothill homes. Many houses here still have the original single-pane windows and uninsulated walls, but the attic is where the most heat enters in summer and escapes in winter, and blown in material fills that space completely, around every joist and wire, without the gaps that batts leave behind. In a climate where summer days exceed 100°F and winter nights dip below freezing, that complete coverage is the difference between a house that holds temperature and one that fights it. We blow GreenFiber cellulose or Johns Manville fiberglass, matched to the attic’s existing condition, and we check ventilation before we start because Tujunga’s canyon-adjacent attics trap heat in ways flatland homes don’t. It’s a job we do often, and we do it with the same materials and methods we describe on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled, you can see the ceiling joists, and your upstairs rooms are always 5 to 10 degrees hotter than the rest of the house.
What it costs in Tujunga
Cellulose insulation in Tujunga typically runs $1.10 to $2.80 per square foot installed, varying with depth and attic accessibility in older foothill homes.
How we do it
We air-seal the attic floor, confirm the ventilation is adequate, then blow GreenFiber cellulose to the specified depth using a calibrated machine, building to R-38 or R-49 as the home requires.
Blown In Attic Insulation
Signs you need it
You see bare framing in the attic, your heating bills climb every winter, and the ceiling feels warm to the touch on summer afternoons.
What it costs in Tujunga
Blown in attic insulation in Tujunga generally costs $1,200 to $4,500 for a typical 1,000 to 2,000-square-foot home, depending on depth and existing-material removal.
How we do it
We remove or level the existing insulation as needed, seal the ceiling penetrations, and blow the material evenly across the entire attic floor to a consistent depth, then re-check airflow at the eaves.
Blown In Cellulose Insulation
Signs you need it
Your home was built before 1970, the attic has thin or deteriorated insulation, and you want a recycled-content material that reduces landfill waste.
What it costs in Tujunga
Blown in cellulose in Tujunga typically runs $1.50 to $3.00 per square foot installed, with GreenFiber material often chosen by Tujunga homeowners who prefer a 85% recycled paper product.
How we do it
We prep the attic by sealing gaps, protect the access point, and blow the cellulose to the depth required for the target R-value, often topping up existing fiberglass rather than removing it.
Blown In Fiberglass Insulation
Signs you need it
You want a material that won’t settle as much as cellulose, resists moisture in the attic, and can be installed over existing batts to reach a higher R-value.
What it costs in Tujunga
Blown in fiberglass in Tujunga generally costs $1.00 to $2.50 per square foot installed, with Johns Manville fiberglass being a common selection for older Tujunga attics prone to moisture.
How we do it
We verify the ventilation and vapor barrier condition first, then blow the fiberglass to the target depth, taking care to keep the eave vents clear so the attic can breathe.
Loose Fill Insulation
Signs you need it
You have an irregular attic with lots of odd angles, pipes, and wires, and the current insulation is patchy or uneven.
What it costs in Tujunga
Loose fill insulation in Tujunga generally costs $0.90 to $2.40 per square foot for the material, with labor added depending on whether it is a new install or a top-up over existing material.
How we do it
We choose loose fill cellulose or fiberglass based on the attic’s moisture history, then blow it into every void and corner the machine can reach, creating a continuous thermal layer.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown in attic insulation (1,000 – 2,000 sq ft home) | $1,200 – $4,500 |
| Cellulose insulation (per sq ft installed) | $1.10 – $2.80 |
| Fiberglass loose fill (per sq ft installed) | $1.00 – $2.50 |
These ranges reflect what we see across Tujunga attics with standard access. An attic with very low clearance, old vermiculite that needs removal first, or a lot of obstructions will land at the higher end.
Can you blow insulation over existing insulation in a Tujunga attic?
Yes, in most cases we can blow new material over existing insulation, provided the old material is dry, free of mold, and not vermiculite. In Tujunga attics where heat buildup has compressed the original layer, topping up is often the most cost-effective fix. Call (844) 241-0737 for an attic assessment.
How long does blown in insulation last in Tujunga’s climate?
Blown in insulation performs well for decades in Tujunga, but the extreme attic heat in foothill homes can accelerate settling, especially in poorly vented attics. Cellulose typically settles 10 to 20% over its life; fiberglass settles less. We check for settling whenever we work on a Tujunga attic.
