Insulation Company in Tujunga, CA
Blown in insulation remains the most practical retrofit for Tujunga’s older wood-frame homes, and it’s the service we recommend most often when a house from the 1940s or 1950s still has empty wall cavities or a thin, settled attic layer. The foothill microclimate here punishes under-insulated homes in both directions: intense afternoon heat pushes through ceilings, then rapid nighttime cooling pulls warmth right back out. Airtight Insulation Co has served Tujunga since 2011, matching each job to the right material instead of forcing one product onto every house. Call (833) 390-7079 for a free estimate.
Why Tujunga Homes Are Different
Tujunga sits at the base of the San Gabriel Mountains, and the daily temperature swing is the defining challenge for insulation work here. A summer day can hit the mid-90s and then drop into the low 60s after sunset. That 30-degree swing means insulation has to manage heat gain and heat loss within the same 24-hour cycle, a demand that’s harder than what you’d see in the flatter valley or basin neighborhoods. Homes here also get strong canyon winds and relentless UV exposure, which breaks down exterior materials and drives air infiltration through even small gaps.
The housing stock compounds the problem. Much of Tujunga was built between the 1920s and 1960s: mid-century ranch homes and cabins with wood framing, minimal original insulation, and retrofit work that varies wildly in quality from house to house. We regularly find attics where someone blew in a few inches of fiberglass decades ago and called it done, not realizing the insulation has settled to half its original depth. Converted garages and unpermitted additions are common too, creating irregular thermal envelopes that make a one-size-fits-all insulation estimate useless. Each house has to be assessed on its own.
Canyon neighborhoods like the ones around Haines Canyon and Stonehurst face a specific issue: attic spaces that bake during the day, then cool so quickly at night that condensation forms on the underside of the roof deck. Over time that condensation settles insulation, reduces its R-value, and can even support mold growth. When we inspect older Tujunga properties, settled insulation and hidden air leaks in the top plates and knee walls show up repeatedly. The fix is rarely just “add more insulation.” It’s sealing the air movement first, then installing material that holds its depth over time.
Our Main Tujunga Services
The two services Tujunga homeowners call about most are attic insulation and spray foam. Each solves a different part of the same problem, and the right choice depends on how your house was built and what you’re trying to fix. Here’s how each one works in this city.
Attic Insulation in Tujunga
Attic insulation is the first place we look in Tujunga because heat moves through the roof more than any other surface. Older ranches and cabins often have attic access through a small interior hatch, and the existing insulation is frequently settled, compressed, or missing over the eaves entirely. We inspect the attic floor, check for air leaks around can lights and top plates, then install material that matches the house. For homes with minimal access, blown-in fiberglass or cellulose gets the job done without tearing up walls. Read the full breakdown on our Attic Insulation in Tujunga page.
Spray Foam Insulation in Tujunga
Spray foam earns its keep in Tujunga’s converted garages, bonus rooms, and unpermitted additions where irregular framing leaves gaps that batts can’t fill. Closed-cell foam air-seals and insulates in the same pass, which matters when canyon winds push air through wall cavities. We install both open-cell and closed-cell foam through Icynene and Demilec, and we let the job pick which formulation to use. 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 mid-century ranches and cabins. Homes built from the 1920s through the 1960s often have empty wall cavities or attic insulation that’s settled to a fraction of its original depth, and blown-in material can be installed through small access holes without gutting the walls. It fills irregular spaces completely, which matters in a city where converted garages and unpermitted additions create odd thermal envelopes. We offer Blown In Insulation using both fiberglass and cellulose, and we select the material based on your house’s exposure, framing, and what you’re trying to accomplish.
Cellulose Insulation
Signs you need it
Rooms that won’t hold temperature, old insulation that has visibly settled below the top of the ceiling joists, or drafts near baseboards in a pre-1970s home.
What it costs in Tujunga
Blown-in cellulose in Tujunga typically runs $1.60 to $3.80 per square foot installed, depending on depth and access.
How we do it
We dense-pack or loose-fill GreenFiber cellulose through strategically placed holes, then seal the access points and verify the settled depth meets the target R-value.
Blown In Attic Insulation
Signs you need it
Your attic floor insulation is patchy, compressed, or missing entirely over the eaves, and upstairs rooms are noticeably hotter than the rest of the house by mid-afternoon.
What it costs in Tujunga
Blown-in attic insulation in Tujunga generally lands between $2,000 and $6,800 for a whole-attic retrofit, with the final number set by square footage and target R-value.
How we do it
We air-seal the attic floor penetrations first, then blow insulation to a consistent depth across the entire attic floor, including the hard-to-reach eave edges.
Blown In Fiberglass Insulation
Signs you need it
You want an attic upgrade that won’t settle as readily, or you prefer a non-organic material that won’t absorb moisture in a condensation-prone canyon home.
What it costs in Tujunga
Blown-in fiberglass in Tujunga typically runs $1.50 to $4.10 per square foot installed, with deeper R-60 attics at the higher end.
How we do it
We install Owens Corning or Johns Manville blown fiberglass to the specified depth, using depth markers to confirm consistent coverage from ridge to eave.
Loose Fill Insulation
Signs you need it
You’re finishing a converted garage or addition in Tujunga and need insulation that fills irregular framing without the labor of cutting batts to fit every odd cavity.
What it costs in Tujunga
Loose fill insulation in Tujunga averages $1.50 to $4.10 per square foot installed, depending on material and whether it goes in walls or an open attic floor.
How we do it
We machine-blow the loose fill at controlled density, which prevents future settling and gives consistent coverage in both open attics and enclosed wall cavities.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown-in cellulose (walls or attic) | $1.60 – $3.80 per sq ft |
| Blown-in fiberglass (walls or attic) | $1.50 – $4.10 per sq ft |
| Whole-attic blown-in retrofit | $2,000 – $6,800 |
How long does blown in insulation last in Tujunga?
Fiberglass and cellulose both hold their R-value for 20 to 30 years when installed at proper density, though Tujunga’s condensation cycles can settle under-installed material within a decade. A properly dense-packed installation removes that risk. Call (833) 390-7079 for an inspection.
Is blown in insulation worth it for a 1950s Tujunga home?
Yes, and it’s usually the most cost-effective retrofit for that era. Empty wall cavities and a thin attic layer let heat pour out all night. Blown-in material fills those cavities without opening the walls, and the comfort difference is usually noticeable within days.
