If you’re in a 1920s bungalow near Magnolia Park or a post-war tract home in the Rancho district, the odds are good your attic is under-insulated, and your upstairs rooms feel it every August. Call (626) 657-5343 and we’ll walk you through what your attic needs, in plain English, before anyone picks up a tool.
Why Thistledown Insulation Pasadena Is Burbank’s Preferred Attic Insulation Company
Neil Barron leads our crews, and he’s the person you’ll talk to when you call. We’re an independently owned Cedarwell location, which means we answer to one standard on every Burbank job: the Cedarwell Care Promise. Shoe covers go on at the front door. Drop cloths run from the entry to the attic hatch. We ask before moving anything in your hallway. And when the attic is done, you get a photo of the clean-up before our van leaves your street.
Burbank homeowners tell us the same thing year after year: they want a crew they can trust to be upstairs while the baby naps and the dog wanders around. That’s why every technician who walks through your door is background-checked and uniformed. You’ll know exactly who’s in your home, and they’ll explain what they’re doing before they do it.
We answer calls with a live person, 24 hours a day, seven days a week. No voicemail trees. No “we’ll get back to you tomorrow.” If you’ve got a question about insulation at 9pm on a Tuesday, a person picks up.
Blown In Insulation in Burbank
Blown In Insulation in Burbank is the most common retrofit we install, and for good reason: it’s fast, it fills gaps and odd cavities that batts can’t reach, and it delivers dramatic thermal improvement in attics that have been cooking at 140°F all summer. We blow fiberglass or cellulose through a hose into the attic floor or wall cavities, achieving a consistent, gap-free layer that older Burbank homes almost never have. A typical blown-in attic retrofit in Burbank runs $1,800 to $4,200 depending on square footage and target R-value.
Fiberglass vs. Cellulose for Valley Heat
In Burbank’s dry inland climate, blown-in fiberglass like Owens Corning AttiCat holds its loft for decades and never settles dramatically. Cellulose, like GreenFiber, is a tighter fit for attic bypasses around recessed lights and chimney chases, but it can weigh more and settle slightly over time. We’ll match the product to your attic’s framing and your family’s priorities, including pet-safe options where a choice exists.
Top-Ups for Legacy Rock Wool
Many Burbank attics still have a thin layer of original rock wool from the 1930s or 1940s. It’s usually settled to half its original R-value or less. If the existing material is dry and free of rodent damage, we can blow new insulation directly over it without full removal, bringing the attic up to R-38 or R-49 and restoring real comfort to the rooms below.
Insulation Contractors in Burbank
Insulation Contractors in Burbank are not all the same, and if you’ve been searching for one, you’ve probably noticed how hard it is to compare quotes. Our approach is different: you get a written price before any work begins, every single time. No wide ranges, no “we’ll see when we get up there.” Neil’s crew will inspect the attic, identify what’s there now, flag anything that needs attention like old wiring, and hand you a number. That number is what you pay.
What a Good Contractor Should Check First
A thorough Burbank attic inspection should look at more than insulation depth. We check for knob-and-tube wiring in homes built before the 1950s, we look for attic bypasses around recessed lights and chimneys, and we test for moisture or rodent activity in the existing material. Skipping any of these leads to a job that underperforms or, worse, creates a hazard. We don’t skip them.
Written Price, Then Work
Our 365-Day Done Right Promise covers every Burbank job. If it’s not done right, we make it right. No debate, no fine print. The written price is part of that same promise: it’s not a teaser, it’s not conditional on anything. It’s the exact number, in writing, before we touch a rafter.
Trusted Brands We Service in Burbank
We install products from Johns Manville, Knauf, and CertainTeed, among eight brands we carry as a Cedarwell-family company. For Burbank’s older attics, we often lean on Owens Corning AttiCat for fiberglass blow-ins and Rockwool for batts where thermal and acoustic performance both matter, like above a nursery or a home office. We don’t stock just one brand and force it into every home. We match the material to the attic, the wiring situation, and the family’s priorities. If you’ve got a preference or a product you’ve researched, tell us, and we’ll tell you honestly whether it fits your attic.
Common Attic Insulation Problems We See in Burbank Homes
- Original rock wool that’s settled and useless. Homes in Magnolia Park and the Rancho district often still have the original 1930s rock wool, now compressed to an inch or less. It’s doing almost nothing, and the attic above is radiating 140°F heat straight into your bedrooms.
- Knob-and-tube wiring hiding under old insulation. In Burbank homes built before roughly 1950, knob-and-tube wiring is common. Blowing insulation directly over live K&T is a fire hazard and a code violation. It must be isolated or addressed by an electrician before insulation goes in.
- Attic bypasses leaking Valley heat. Gaps around recessed lights, chimney chases, and plumbing vents let hot San Fernando Valley air pour into the attic and press down into living spaces. Even a brand-new insulation layer performs far below spec if these bypasses aren’t sealed first.
- Upstairs rooms that never cool below 85°F. This is the complaint we hear most in Burbank’s two-story bungalows. The cause is almost always an under-insulated attic, not a failing HVAC system. Adding proper attic insulation often fixes the room while cutting summer cooling bills.
Pricing for Attic Insulation in Burbank, CA
Here are the numbers Burbank homeowners should expect. A blown-in attic top-up over existing insulation typically runs $1,200 to $2,400, depending on depth needed. A full removal of old rock wool or rodent-damaged material followed by new blown-in insulation runs $2,800 to $4,200. Batting a small attic or a single room’s attic space runs $900 to $1,800. If knob-and-tube wiring is present and needs isolation, that work is coordinated separately with a licensed electrician and priced by them, not us. Your exact written price comes after a free in-attic inspection. Call (626) 657-5343 and we’ll schedule it.

FAQs About Attic Insulation in Burbank
Not always. If the existing rock wool is dry, free of rodent contamination, and not covering knob-and-tube wiring, we can blow new insulation directly over it. If it’s been wet, is full of droppings, or is sitting on live K&T, it needs to come out first. Our inspection will tell you which situation you have, and the written price will reflect it. Call (626) 657-5343 for a free inspection.
Knob-and-tube wiring cannot be covered with insulation. It relies on open air to dissipate heat, and burying it creates a fire risk. In a Burbank home with K&T, the wiring runs must be isolated, decommissioned, or replaced by a licensed electrician before we blow in insulation. We flag it during inspection and coordinate the sequence so the electrician’s work and ours happen in the right order. Call (626) 657-5343 and we’ll explain exactly what needs to happen in your attic.
For Burbank’s hot, dry valley climate, we recommend R-38 to R-49 in the attic. That’s the range that keeps summer heat from radiating down into your rooms while holding warmth on the occasional cold winter night. Older Burbank homes with original rock wool often sit at R-10 or less, which is why upstairs rooms swelter. The specific target for your home depends on the attic’s depth and the framing, and we’ll confirm it in the written estimate.
Yes, and it often does substantially. Attic heat is the single biggest driver of upstairs-room overheating in Burbank. Insulating the attic properly reduces that heat load immediately, which means your AC runs less. Uninsulated walls are a separate issue that can be addressed later, but the attic is where you’ll feel the difference first, and it’s where the cost-to-benefit ratio is strongest. Ask for a free assessment to see what your attic alone can do for your bills.
Most 1920s Burbank bungalows with a standard attic take four to six hours from start to clean-up. That includes prep, blowing the insulation to the target depth, and documenting the finished job. If we find knob-and-tube wiring or need to remove old material first, the job may extend to a second day after the electrician’s work is done. We’ll give you a clear timeline before we start, and you’ll have the written price before that.
Field Notes from a 1930s Magnolia Park Bungalow
Our crew recently worked on a 1930s bungalow in Magnolia Park where the attic had only a thin layer of original rock wool and the homeowner complained of a bedroom that never cooled below 85°F. We blew in Owens Corning AttiCat fiberglass to R-38, but first we had to flag and isolate the knob-and-tube wiring runs and coordinate with an electrician. The result was an immediate drop in summer energy bills and a fully usable upstairs bedroom. That sequence, inspect, flag, coordinate, then insulate, is the same one we follow on every older Burbank home. Thistledown is the soft fluff of the thistle, one of nature’s lightest insulators. The name is a promise about how carefully we work.
