GreenFiber Insulation Removal & Replacement in Burbank: What to Know First
GreenFiber insulation removal and replacement in Burbank typically runs $1.50 to $3.60 per square foot depending on attic access, contamination level, and whether air sealing is added, with most jobs completed in a single visit. We’re an independent GreenFiber service provider, not an authorized dealer, which means we diagnose what’s actually wrong with your existing insulation before recommending a fix. If you own a home in Burbank with settled, damp, pest-damaged, or dust-heavy GreenFiber blown-in insulation, call (747) 837-5834 and a live person will answer, day or night.

Key Takeaways
- GreenFiber is a cellulose-based blown-in product that settles and degrades differently than fiberglass or mineral wool
- Most Burbank removal jobs are driven by moisture, rodent contamination, or severe settling, not product defect
- Replacement with fresh GreenFiber, Rockwool, or Owens Corning fiberglass depends on your attic’s moisture profile and existing air leaks
- We complete the majority of GreenFiber removal and replacement jobs in one day
- Every job is backed by our 90-Day Done Right Promise in writing
How GreenFiber Products Fail - and How We Fix Them
GreenFiber makes several blown-in cellulose products: GreenFiber Cellulose Insulation (loose-fill), GreenFiber Fire-Resistant Cellulose, and their all-borate-treated TrueComfort line. Each holds up differently in Burbank’s hot, dry summers and cool, damp winter mornings. Here’s what we actually see when we open attics across the city:
- Moisture absorption in can-light areas and eaves. Cellulose fibers are treated with borates for fire and pest resistance, but Burbank’s winter condensation cycles can still wick moisture at thermal bridges. In Magnolia Park bungalows with original 1940s wiring and recessed lighting, we regularly find damp, compacted GreenFiber packed against warm can housings. The fix: removal, targeted air sealing around the fixtures, and either new GreenFiber or Rockwool batts over the sealed areas.
- Settling in cathedral and vaulted ceilings. Loose-fill cellulose settles 13% to 20% over time, more in Burbank’s steep-pitched roofs where gravity works against the loose fibers. Homes near the Verdugo foothills with exposed beam ceilings often show a 3- to 4-inch R-value loss at the peak vault. We remove the settled material and either re-blow with stabilized GreenFiber or switch to a batt product that holds position in sloped cavities.
- Rodent nesting that turns insulation into a health hazard. Rats and mice tunnel through loose cellulose more eagerly than through fiberglass. Once they nest, the material is contaminated with urine and droppings and has to go. In Burbank neighborhoods with citrus trees and older garages, this is the most common GreenFiber removal call we get. We remove the contaminated material, sanitize the attic floor, rodent-proof entry points, and install fresh insulation under our attic cleaning and rodent proofing service.
- Dust and particulates from older GreenFiber batches. Early-2000s GreenFiber used a less refined newsprint feedstock in some plants. Those attics shed fine particles that work their way into the home through ceiling penetrations. If you notice a fine gray dust accumulating on ceiling fan blades or around recessed light trims in a Burbank home built between 1998 and 2006, the culprit is often degraded cellulose. Removal and replacement solves the dust at the source.
- Improper original installation, especially at soffit vents. Burbank homes from the 1980s and 1990s often had GreenFiber blown in without baffles at the eaves. The result: insulation blocking soffit vents, killing attic ventilation, and trapping heat. That’s why attics hit 140 degrees in August and the cellulose cooks, dries, and compacts. We remove the compromised material, install proper baffles, and re-blow the correct depth. Good insulation shouldn’t be something you think about - that means it’s working.
Our GreenFiber Insulation Removal & Replacement Process
- 1
Call and schedule. You reach a live person at (747) 837-5834, 24/7. We ask about the home’s age, attic symptoms, and any known pest or moisture issues so the tech arrives prepared. Most Burbank jobs are quoted on-site the same visit.
- 2
Full attic assessment. Neil Ashford or one of our background-checked, uniformed techs inspects the existing GreenFiber for settling depth, moisture content, rodent activity, and ventilation blockages. We photograph everything so you see exactly what we’re seeing.
- 3
Removal approach decision. Depending on access and contamination level, we use commercial HEPA-filtered vacuum systems to pull the old cellulose out cleanly. No garbage bags dragged through your hallway, no dust storm in your living room.
- 4
Air sealing and prep work. Before any new insulation goes in, we seal top plates, wire penetrations, can-light housings, and attic hatches. Skipping this step is why so many homes with fresh insulation still feel drafty. This is the part most contractors miss, according to Neil, and it makes the biggest difference in Burbank’s 30-degree winter mornings.
- 5
Replacement installation. We re-install GreenFiber TrueComfort, Rockwool, or Owens Corning fiberglass based on your attic’s moisture profile, your budget, and the existing venting setup. Not every attic should get cellulose back, and we’ll tell you honestly which way to go.
- 6
Clean-up and the Done Right Promise. We leave the work area cleaner than we found it and walk you through what was removed and installed. Every job is backed by our 90-Day Done Right Promise: if it’s not right, we make it right.

FAQs
No. GreenFiber’s product warranty covers manufacturing defects and has nothing to do with removal or replacement by a licensed contractor. If your insulation has failed because of settling, moisture, or contamination, the warranty won’t cover that anyway. The real question is whether your home is performing, and that’s what we test before and after every job. Call (747) 837-5834 and we’ll tell you honestly whether replacement makes sense in your Burbank attic.
Most standard attics, 1,200 to 1,500 square feet, are removed and re-insulated in a single day. If we find extensive rodent damage or need to repair venting, it can stretch to a second visit, but we’ll tell you before work starts. Call us for a same-week schedule, a live person answers 24/7.
Sometimes it is, and we’ll tell you when that’s a bad idea. If the existing cellulose is dry, pest-free, and only lightly settled, topping off with fresh GreenFiber can save you real money. But if there’s moisture, rodent activity, or dust migration into the house, layering new insulation over the problem just buries it. We only remove what actually needs to be removed.
When we re-install cellulose, we typically use GreenFiber TrueComfort, the all-borate-treated line. But we also install Owens Corning and Rockwool products where the attic’s moisture and ventilation profile calls for something different. We’re not attached to one manufacturer. We’re attached to doing it right.
Yes, in most cases. Call (747) 837-5834, talk to a live person, and we can usually get a technician to your Burbank home the same day or next morning. Estimates are free, and you’ll get a written quote before any work starts.
