Fast, Reliable Attic Insulation Across Burbank
Attic insulation work in Burbank generally costs between $1,800 and $4,600 for a full retrofit, depending on whether we’re topping up settled fiberglass or air-sealing and upgrading an entire 1940s bungalow attic. Most Burbank jobs are driven by one thing: San Fernando Valley summer heat pouring through an under-insulated vented attic and turning the upstairs into a saucer. We know Burbank’s housing stock from the 1920s bungalows near downtown to the 1960s tracts up in 91504, and we know exactly what those attics were built with, which is usually not much.

Why Cozy Insulation Co Is Burbank’s Preferred Attic Insulation Company
We’ve spent enough time in Burbank attics to know the difference between a 1935 Spanish stucco on Olive Avenue and a 1958 tract home off Glenoaks Boulevard. The framing, the clearances, the venting, the access, they all vary by era and subdivision. Homeowners across the 91505 and 91506 zip codes keep calling us because we do the work ourselves, no subcontractors, and we don’t pitch a single material and pretend it fits every house.
Mike Callahan runs our crews, and his rule from day one has been simple: match the material to the home and the homeowner’s actual problem. Some Burbank attics need air-sealing and Owens Corning batts. Others need closed-cell Demilec spray foam because the kneewalls are practically open to the roof deck. We’ll tell you which is which and why, then we’ll install it correctly the first time.
Radiant Barrier in Burbank
Radiant barrier work in Burbank is one of the highest-return upgrades we do, because in this part of the San Fernando Valley your attic’s underside can hit 140°F on a July afternoon, and that heat doesn’t just sit up there, it radiates down through the ceiling and into your living space. In Burbank’s older vented attic homes, adding a radiant barrier under the roof deck is often the most direct way to cut that heat load before it ever reaches your insulation. We typically install radiant barrier as part of an attic retrofit, and depending on attic square footage and accessibility, Burbank homeowners usually spend between $900 and $2,200 for the barrier portion of the job. That’s before any insulation top-up or air-sealing, which most pre-1970 homes also need.
Where Radiant Barrier Pays Off Fastest
Homes in the 91501 and 91502 core with low-pitched roofs and tight attic clearances get hit hard by radiant gain. A properly installed radiant barrier up against the roof deck in those attics reflects most of the incoming heat before it can soak into the insulation below. It’s not a substitute for a full insulation job, but paired with air-sealing it changes how the upstairs feels by late afternoon.
Combining Radiant Barrier with Attic Insulation
For Burbank tract homes from the 1950s and 60s, the best result usually comes from stacking radiant barrier, air-sealing, and fresh insulation. The barrier knocks down the peak radiant load, the air-sealing stops the conditioned air from escaping, and the insulation resists what’s left. We’ll price the layers separately so you can see what each piece costs and decide what fits now.
Attic Cleaning Services in Burbank
Attic cleaning services in Burbank are about more than tidiness, and we don’t mean that lightly. The same duct leaks and unsealed top plates that make a 1940s bungalow or a 1960s tract home uncomfortable in August also pull dust, debris, and sometimes rodent remnants into the attic insulation, contaminating what’s there and cutting its effectiveness. In Burbank’s older homes, decades of dust settle into the fiberglass and dry out the air in ways that undermine both comfort and indoor air quality. We remove the old, contaminated material, clean the attic floor and joists, and prep the space for fresh installation.
What Attic Cleaning Covers
We remove old, pancaked, or pest-damaged insulation using commercial vacuums, then sanitize the affected areas before any new material goes in. If you’ve had squirrels or rats, which are common enough in the Magnolia Park and Rancho neighborhoods, the cleanup has to happen before insulation. We handle the whole sequence.
Why Older Burbank Homes Need It First
If your attic still has whatever insulation was there when the house was built, it’s probably compacted to a fraction of its original depth. Adding new insulation on top of that traps the problem. In Burbank’s pre-1970 stock, we generally recommend a full remove-and-clean before a retrofit, so the new material starts from a clean, sealed deck.

Trusted Brands We Service in Burbank
We install attic insulation using products from Owens Corning, Johns Manville, GreenFiber, and Demilec, which means we’re not limited to whatever one brand happens to make. For Burbank’s older vented attics, Owens Corning and Johns Manville batts are solid, proven workhorses. For a tighter air-seal and higher R-value in a kneewall or attic flat, Demilec closed-cell spray foam is the upgrade that makes the biggest difference. GreenFiber cellulose works well for homeowners in Burbank who want recycled-content blown-in material without sacrificing performance. We keep common batt sizes and spray foam systems stocked for fast turnaround on Burbank jobs, so you’re not waiting on a supplier out in Valencia.
Common Attic Insulation Problems We See in Burbank Homes
- Settled, pancaked fiberglass in 1940s-60s attics. Original insulation from the aircraft-boom era has compressed over decades to a thin, almost useless layer. Radiant heat blows right through it, and the upstairs never holds its temperature.
- Uninsulated kneewalls and top plates. Builders in Burbank’s postwar subdivisions paid almost no attention to the small vertical walls and plate lines in attics. Hot attic air moves through those gaps into living space all summer.
- Leaky drop-down attic stairs and whole-house fans. These are the big hidden air leaks in older Burbank homes. A 1950s whole-house fan has essentially no seal, and drop-down stairs rarely fit tight, so cooled air pours out all afternoon.
- Pest-damaged or contaminated insulation. Squirrels and rats in Magnolia Park and the hillside streets of 91501 and 91502 soil insulation and reduce its R-value. We deal with this on a regular basis before recommending any new material.

FAQs About Attic Insulation in Burbank
The usual culprits in Burbank are uninsulated kneewalls, thin settled fiberglass, and a vented attic that was never air-sealed. If your neighbor’s attic has more insulation or a more recent retrofit, it’ll run noticeably cooler, even in the same 95-105°F stretch across the San Fernando Valley. We can inspect your attic and show you exactly where the heat’s getting through. Call (855) 382-3925 for a free estimate.
In almost every case, we recommend capping the fan opening and switching to modern, less leaky ventilation rather than trying to hold onto the original whole-house fan. A 1950s fan that’s still in place is an enormous air leak, and it’s working against the air-sealing that makes your attic insulation effective. We’ll seal and insulate the opening so that the fan’s role in the house no longer costs you comfort.
Yes, we deal with this on nearly every pre-1970 Burbank home we service. Drop-down attic stairs almost never close airtight, so we install an insulated cover box or gasket seal, and we air-seal around the frame. That stops the conditioned air from escaping and lets your attic insulation do its actual job. It’s a small line item that pays off every summer afternoon.
Burbank’s insulation problem is about 90% summer. Your attic is absorbing the San Fernando Valley’s 95-105°F heat and radiating it down into the rooms below, while winters here are mild enough that heat loss is a distant second concern. The right retrofit for Burbank is built around resisting radiant gain in the attic, not adding R-value for winter. That’s why we lead with air-sealing, radiant barrier, and properly sized insulation rather than a blanket R-value pitch.
We install fiberglass batts from Owens Corning and Johns Manville, blown-in cellulose from GreenFiber, and spray foam from Demilec. That gives us the flexibility to match the material to your Burbank home’s age, attic design, and your actual comfort problem, rather than pushing one product on every house. Call (855) 382-3925 and we’ll walk you through what fits yours.
If your Burbank attic is hot, drafty, or just not doing its job, call (855) 382-3925 for a free, no-pressure estimate. We’ll inspect the attic, tell you what’s actually wrong, and give you a line-item price for the fix. We serve all of Burbank, from the 91501 bungalows to the 91508 hillsides.
