Insulation Company in Burbank, CA
Blown in insulation is the most practical retrofit for Burbank’s 1940s – 1960s stucco bungalows and ranch homes, where original batt insulation has compressed to a fraction of its rated R-value. These single-story houses bake under San Fernando Valley heat, and the fix is usually dense-pack cellulose or loose-fill fiberglass in vented attics and uninsulated walls, installed without tearing out finished interiors. Airtight Insulation Co has served Burbank since 2011, and our crews understand the tight lots, shallow rafters, and occupied homes that define this city’s retrofit work. Call (833) 390-7079 to talk through what your house actually needs.
Why Burbank Homes Are Different
Burbank sits at the east end of the San Fernando Valley, where summer days routinely cross 100°F and attic temperatures climb far higher. The housing stock is dominated by single-story stucco bungalows and small ranch homes built during the Lockheed-era boom, most with vented attics and original batt insulation that has long since settled into a thin, barely functional layer. The same house that overheats in August loses heat on cold valley-floor winter nights, so attic retrofits pay back on both sides of the year.
The older 91501 and 91506 bungalows present a specific challenge. Many still carry the original shallow rafters and top-plate wiring, which means a proper insulation job involves tucking material around knob-and-tube-era penetrations and recessed can lights rather than simply blowing an even blanket across the attic floor. Burbank’s densely packed lots add another constraint: the compressor has to sit tight to a property line, and crews work around finished interiors and neighbors’ fences. The city also enforces California’s Title 24 cool-roof and insulation requirements strictly, so the real pitch here is code-compliant attic upgrades that cut AC load in valley heat, not a quick topping-off job that misses the air-sealing work.
Our Main Burbank Services
Burbank homeowners call us most often about two things: attic insulation that has failed in the valley heat, and spray foam for air sealing that a standard batt install cannot deliver. Each service gets its own dedicated Burbank page with full pricing detail.
Attic Insulation in Burbank
Most Burbank attics we inspect have R-19 batts that are compressed, dust-covered, and performing closer to R-9 or R-11. In a 100°F valley summer, that means the air conditioner works against a ceiling that radiates heat all afternoon. Our attic retrofits start with air sealing at top plates, can lights, and plumbing penetrations, then add loose-fill or batt insulation to hit Title 24 levels for Burbank’s climate zone. We work around the shallow rafters and existing wiring common in 1940s and 1950s builds. Read the full breakdown on our Attic Insulation in Burbank page.

Spray Foam Insulation in Burbank
Closed-cell spray foam earns its cost in Burbank when a homeowner wants both R-value and an air barrier in one application. It performs well in tight attic cavities and on knee walls where the valley’s hot afternoons punish under-insulated space. Open-cell foam makes more sense for interior sound control and for filling irregular cavities in older remodeled homes. Through Icynene and Demilec, we carry both formulations and let the job pick the product. See Spray Foam Insulation in Burbank for what each material costs here.

Blown In Insulation in Burbank
Blown in insulation solves the most common problem in Burbank’s older housing stock: original batt insulation that has compressed to nearly nothing after sixty or seventy years in a vented attic. In the 91505, 91506, and 91507 flats, loose-fill cellulose or fiberglass can be installed quickly and evenly over existing material, filling the gaps that let valley heat pour through ceilings all summer. Because Burbank’s dense lots and finished interiors make demolition-based retrofits impractical, blown in is usually the least disruptive route to a real R-value upgrade. See our full Blown In Insulation service hub for material options and the trades we cover.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the tops of the joists, leaving the ceiling warm to the touch on summer afternoons.
What it costs in Burbank
Blown-in cellulose in Burbank typically runs $1.00 – $2.50 per square foot installed, depending on attic depth and access.
How we do it
We dense-pack or loose-fill GreenFiber cellulose to the depth required for Burbank’s climate zone, air-sealing top plates and can-light housings first.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic run 8 – 10°F hotter than the rest of the house on summer afternoons, and your AC cycles constantly.
What it costs in Burbank
Blown-in attic insulation in Burbank generally lands between $1.50 and $3.00 per square foot for a complete R-38 upgrade over compressed existing material.
How we do it
We seal the attic floor penetrations, mark the target depth, and blow loose-fill to a consistent level across the entire attic, including around the shallow rafter tails common in 91501 bungalows.
Blown In Cellulose Insulation
Signs you need it
Your energy bills spike every summer, and an inspection shows gaps where old insulation has shifted away from the eaves and top plates.
What it costs in Burbank
Blown-in cellulose runs $1.00 – $2.50 per square foot installed in Burbank, with GreenFiber the standard recycled-content option we stock for valley jobs.
How we do it
After air sealing the attic floor, we blow GreenFiber cellulose to a measured depth that meets Title 24 requirements for Burbank’s climate zone and then verify with a depth gauge.
Blown In Fiberglass Insulation
Signs you need it
You have an older attic with patchy batt coverage and want a cost-effective loose-fill upgrade that will not settle the way cheap cellulose can.
What it costs in Burbank
Blown-in fiberglass in Burbank typically costs $1.20 – $2.75 per square foot installed, using Owens Corning or Johns Manville loose-fill from our local inventory.
How we do it
We run a hose from a truck-mounted blower up through the attic access and distribute fiberglass to a consistent R-38 or higher depth, keeping the equipment tight against the property line on Burbank’s small lots.
What Blown In Insulation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Blown-in attic (complete R-38 upgrade) | $1.50 – $3.00 / sq ft |
| Blown-in cellulose | $1.00 – $2.50 / sq ft |
| Blown-in fiberglass | $1.20 – $2.75 / sq ft |
Is blown in insulation worth it in Burbank’s heat?
Yes. A full blown-in retrofit in a Burbank attic cuts ceiling heat gain enough that most homeowners notice lower AC run times the first summer. Compared to batts, blown in fills gaps and irregular rafter bays better.
How long does blown in insulation take in a Burbank home?
Most Burbank attics are done in a single day. Tight access hatches and shallow rafters can add an hour or two, but the actual blowing process is fast and non-invasive.
Brands We Service in Burbank
We stock and install eight manufacturer lines, so the material follows the job rather than the other way around. For Burbank’s blown-in work, that usually means GreenFiber cellulose or Owens Corning loose-fill fiberglass, with Johns Manville and Knauf batts available for hybrid jobs. Parts and material run locally through our valley supply chain, so turnaround on a standard Burbank attic is one to two days. Browse our brands for the full lineup.

What Burbank Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Claudia Morales"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."
— Simone Grant"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
