We’ve worked the full cross-section of Burbank housing, from 1940s Lockheed bungalows in Magnolia Park to townhomes off Glenoaks Boulevard and ranch homes in the Rancho adjacency. Dispatch and scheduling run from our Los Angeles office, but the crews serving Burbank live in the Valley and know the local building stock, the parking constraints around Downtown Burbank, and the specific headache of insulating homes that sit directly under Hollywood Burbank Airport flight paths.

Homeowners in Burbank specifically mention the written price guarantee and the 365-Day Done Right Promise in their reviews, and they return when they buy their next property because the documentation travels with them.
Response time to Burbank averages same-day or next-day scheduling. We don’t use callback windows measured in business days. A live person answers calls 24/7, and you’ll get a text when your technician is en route with a name and ETA. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
Local knowledge matters here in ways it doesn’t in neighboring markets. Burbank’s 1940s-1960s bungalows and ranch homes were built fast for Lockheed and studio workers, with zero wall insulation and attic fill that has settled to near-uselessness over six decades. We know how to access those wall cavities without tearing out plaster, how to verify bag counts so you don’t get under-filled hot spots, and how to address the acoustic demands that come with living under active flight corridors.
Our Blown-In Insulation Services in Burbank
Blown-In Cellulose
We use GreenFiber cellulose for most Burbank attic jobs and dense-pack wall fills. Cellulose runs about $1.80-$2.40 per square foot installed in Burbank attics, and it performs particularly well here because its higher density compared to fiberglass adds measurable acoustic dampening. That’s not a minor benefit in the flight-path corridors north of Magnolia Boulevard, where daily jet traffic from Hollywood Burbank Airport makes STC ratings as relevant as R-values. We specify full-cavity fill and verify even density before sealing around penetrations.
Blown-In Fiberglass
Owens Corning blown-in fiberglass runs $1.50-$2.10 per square foot in typical Burbank attic jobs. It’s lighter, faster to install, and ideal for open attic floors where we’re topping up existing insulation that has compressed over decades. In Burbank’s inland San Fernando Valley heat trap, where summer temperatures regularly hit 10-15°F above coastal LA, that extra R-value on the attic floor translates directly to reduced AC runtime and lower utility bills. We pair it with thorough air sealing of top plates, can lights, and duct penetrations before any material goes in.
Dense-Pack Wall Insulation
This is where we spend most of our time in Burbank’s 1940s-1960s housing stock. Dense-pack wall insulation runs $3.50-$5.50 per square foot of wall area in Burbank, and it’s the only practical way to insulate walls that were built with no cavity fill at all. We drill access holes through exterior siding or interior drywall, blow cellulose at 3.5-4.0 pounds per cubic foot to achieve the friction-fit density that stops convection, then patch and match texture. The acoustic benefit is substantial in flight-path neighborhoods, and the thermal improvement is immediate. On a 1948 ranch in Magnolia Park with zero wall insulation and attic fill that had settled to barely an inch, our crew ran a dense-pack wall job using GreenFiber cellulose through the existing exterior wall cavities, then topped up the attic with Owens Corning blown-in fiberglass to hit both thermal and acoustic targets. The homeowner’s main ask was cutting jet noise from the airport corridor, so we focused on full-cavity fill and verified even density before sealing around recessed lights. The result was a measurably tighter envelope and a noticeable drop in both heat gain and overhead aircraft noise inside the living space.
Blown-In Top-Up
A blown-in top-up in Burbank typically costs $1,200-$2,800 and addresses the most common problem we see: insulation that has settled, compressed, or degraded over 60+ years to a fraction of its original R-value. We don’t blow over old material without first verifying what’s there. Our crew photographs the existing layer, measures depth across multiple attic locations, and calculates whether a top-up will achieve target R-value or if removal and replacement is the honest recommendation. You get those photos and the calculation in writing before we start.

AfterTrusted Brands We Service in Burbank
We source blown-in materials from Owens Corning, Johns Manville, GreenFiber, and Demilec, with no proprietary product lock-in. That means we specify what performs for your specific Burbank home, not what moves a particular manufacturer’s volume. For attic top-ups in standard ranch homes south of Magnolia Boulevard, we might recommend Owens Corning fiberglass for speed and value. For dense-pack wall jobs in flight-path corridors where acoustic performance matters, we typically lead with GreenFiber cellulose for its higher installed density. Our blower trucks carry multiple material types, so we’re not making a second trip because the spec changed on-site. Turnaround on most Burbank jobs is same-day completion once we start.
Common Blown-In Insulation Problems We See in Burbank Homes
- Installing blown-in without accounting for Burbank’s dense, offset two-car garages and townhome shared walls. Hose runs in tight clearances can punch through fire-rated separations or leave uninsulated shared-cavity gaps if the installer doesn’t map the cavity network first. We verify wall construction type before drilling.
- Treating attic top-ups as purely thermal in flight-path neighborhoods. Skipping the dense-pack density needed for acoustic performance leaves jet noise attenuation on the table. In Magnolia Park and the corridors north of Magnolia Boulevard, we spec for both R-value and STC from the first conversation.
- Ignoring the settled, compressed 60-year-old insulation layer in 1940s-60s Lockheed/studio bungalows. Blowing over degraded fill without bag-count verification creates under-filled areas and hot spots above living rooms. We measure before we add.
- Sealing after insulating instead of before. Blowing insulation over an unsealed attic floor is putting a blanket on a sieve. Our crews complete air sealing of top plates, can lights, and all penetrations before any insulation hose runs.

FAQs - Blown-In Insulation in Burbank
Yes, when it’s specified for acoustic performance, not just thermal. Dense-pack cellulose at 3.5-4.0 pounds per cubic foot provides measurable STC improvement in exterior walls, and full-cavity fill eliminates the resonant air gaps that transmit aircraft noise. We verify density with a cavity-fill check, not guesswork. Call (213) 306-2607 for a free estimate that includes both R-value and acoustic targets.
We drill strategic access holes through exterior siding or interior drywall, blow cellulose to friction-fit density, then patch and texture-match. For 1940s-1960s Burbank bungalows, this is standard practice, not a custom job. The key is mapping cavity networks first to avoid shared-wall gaps or fire-rated separation breaches. You’ll get photos of every access point and the filled cavity before we patch.
Cellulose or fiberglass both work, but the critical factor is air sealing first. Burbank’s inland valley position traps heat, and an unsealed attic floor with new insulation on top still leaks conditioned air. We seal, then insulate, then verify with a blower-door test on applicable jobs. For pure thermal performance in open attics, Owens Corning fiberglass at R-38 to R-49 is the most common spec we write in Burbank.
Yes, but it requires pre-job mapping of cavity boundaries and fire-rated separations. We don’t drill until we know which walls are shared, which are fire-rated, and where hose runs can be managed without crossing into adjacent units. For properties with alley-load garages or zero side-yard access, we use smaller-diameter hoses and staged material drops. The written scope specifies exactly which walls are in scope before we start.
We measure depth at multiple attic locations, photograph the existing material condition, and calculate current R-value against target. In Burbank’s 1950s housing stock, we regularly find original insulation compressed to 1-2 inches, effectively R-3 to R-6 in a climate that calls for R-38 minimum. You get the photos, the measurements, and the calculation in writing. If a top-up won’t get you to target, we’ll recommend removal and replacement with a clear price for both options.
