Trusted Blown-In Insulation for Burbank Homeowners
Blown-In Insulation in Burbank typically costs between $1.80 and $3.20 per square foot installed, with most attic jobs running $2,400-$5,800 depending on depth, material, and whether air sealing is needed first. At Topside Attic Insulation Burbank, we’ve sealed and insulated over 9,000 homes since 2016, and every job starts with a written price before any work begins. Our crews are background-checked, uniformed, and available with same-day response throughout Burbank, from the hillside homes above Glenoaks Boulevard to the vintage ranches near the studios. Call (213) 816-1699 and a live person answers, 24/7.
Burbank’s climate puts unique stress on attic insulation. Summer afternoons above 95°F in the Verdugo foothills force air conditioners to run longer than in coastal Los Angeles, while winter nights below 45°F let heat escape fast through undersized or settled insulation. Many Burbank homes built between 1940 and 1980 carry original fiberglass batts compressed to half their R-value, or nothing at all above the top plates. We see this regularly in the Magnolia Park area and the flat-roofed midcentury homes near the Burbank airport. Our approach is different: we seal first, then insulate, and we prove the result with before-and-after blower-door numbers on every applicable job.
What Our Blown-In Insulation Service Includes
Blown-In Cellulose
Blown-in cellulose is ground paper fiber treated with borate fire retardant, dense enough to slow air movement through attic floors while achieving R-3.2 to R-3.8 per inch. In Burbank, we specify cellulose for homeowners who want the highest recycled content and superior sound dampening from helicopter traffic and studio generator noise, especially in the hillside neighborhoods below the Verdugo Mountains. Our crews install to a settled depth of 10-14 inches for R-38 to R-49 performance, and we never blow over an unsealed attic floor. Top plates, can lights, and plumbing penetrations get sealed first under Haven Standard Clause 1, with the written scope delivered before anyone lifts a tool.

Blown-In Fiberglass
Blown-in fiberglass uses spun glass fibers with higher loft and lower weight than cellulose, achieving R-2.2 to R-2.7 per inch and excelling in attics with limited load-bearing capacity. We recommend it for Burbank homes with raised-heel trusses or dimensional lumber roof structures where every pound matters, particularly in the postwar neighborhoods between Victory Boulevard and Olive Avenue. Our fiberglass installs include Owens Corning AttiCat or Johns Manville Climate Pro systems, and we verify coverage depth with attic rulers photographed for the Documented Photo Record you receive at job completion. Like every install we do, it follows air sealing of all accessible leaks.

Dense-Pack Wall Insulation
Dense-pack wall insulation fills enclosed wall cavities at 3.5 pounds per cubic foot for cellulose or 1.5-2.0 pounds for fiberglass, dense enough to resist settling and reduce convection looping inside the stud bay. In Burbank, this matters for the 1950s-1970s tract homes in the Rancho area and the condo conversions along Riverside Drive, where walls were built empty or with thin rock wool that has slumped to the bottom. We access walls through exterior siding or interior drywall patches, depending on your finish schedule, and we test our work with infrared scanning to verify fill completeness. The written scope specifies access method, patch responsibility, and expected R-value before we start.

Blown-In Top-Up
Blown-in top-up adds loose-fill material over existing insulation that has compressed, shifted, or been disturbed by prior work, common in Burbank attics where HVAC contractors have trodden down pathways to air handlers. We inspect the existing layer first: if it’s fiberglass batt compressed below its labeled thickness, or cellulose with rodent contamination, we quote removal and replacement instead. When the existing material is clean and viable, we calculate the additional depth needed to reach current Title 24 standards and install matching or compatible material. The job closes with blower-door testing when air sealing is part of the scope, so you see the actual performance change in CFM50.

Brands We Service for Blown-In Insulation

We source blown-in insulation materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, with no proprietary lock-in that limits your options. Owens Corning’s AttiCat expanding fiberglass system is our standard for lightweight attic installs in Burbank’s older homes with 2×4 or 2×6 ceiling joists; we’ve placed thousands of bags and stock the exact blower settings for their R-38 and R-49 coverage charts. Johns Manville’s Climate Pro formaldehyde-free fiberglass goes into homes where indoor air quality is the primary concern, particularly in the Burbank hills where residents have chemical sensitivity concerns and want the lowest VOC option available.
Knauf’s EcoFill and GreenFiber’s All Borate cellulose are our go-to for homeowners prioritizing recycled content and sound attenuation. Knauf’s binder system resists settling in Burbank’s temperature-swung attics, and GreenFiber’s shredded newsprint with borate treatment handles the occasional roof leak without supporting mold growth. Whether your existing insulation is Owens Corning, Johns Manville, Knauf, GreenFiber, or any other make, we can match it for top-up work or replace it with the material that fits your performance goals and budget. Every choice is documented in your written scope before work starts.
Before
AfterSigns You Need Blown-In Insulation Right Now
- Your upstairs rooms run 8-15°F warmer than downstairs in July. In Burbank, this temperature split is the classic signature of an underinsulated attic floor. Heat radiates down from roof decking that reaches 140°F or more, overwhelming your duct system’s capacity. We measure the attic’s current R-value and identify where it’s thinnest, often above master bedrooms that were added in 1980s remodels.
- Your energy bill spikes every August and January. Burbank Water and Power customers with poorly insulated homes see summer cooling costs 40-60% above comparable square footage in the same neighborhood. The difference is usually attic performance. We compare your usage patterns to blower-door and infrared findings to show exactly where conditioned air is escaping.
- You can see floor joists through your attic insulation. Original insulation in Burbank’s pre-1978 homes was often installed at R-19 or less, and decades of settling, disturbance, and moisture cycling have compressed it further. Joists visible above the insulation layer mean you’re getting half the labeled performance or less. Our top-up or replacement calculation starts with a depth measurement and density check.
- Your HVAC runs constantly on hot days but never reaches setpoint. This is often misdiagnosed as an undersized air conditioner. In Magnolia Park and the Chandler corridor, we’ve found attic floors leaking 3,000+ CFM50 of conditioned air into vented attics, making the mechanical system fight a battle it can’t win. Air sealing plus blown-in insulation fixes the building envelope problem so the equipment can do its job.
- Ice dams formed on your roof during the February 2023 freeze. Burbank’s rare hard freezes exposed homes with heat loss patterns that melt roof snow unevenly. Ice dams mean warm air is reaching the roof deck through gaps in insulation and air sealing. We trace the thermal bypasses with infrared cameras and seal them before adding blown-in material to prevent recurrence.
Our Blown-In Insulation Process - Step by Step

- 1
Written price and scope before any work starts. We inspect your attic, measure existing insulation depth, run a blower-door test when accessible, and deliver a flat price with a written scope and written warranty. Haven Standard Clause 1: no work begins until you have all three documents in hand. This takes 45-90 minutes for most Burbank homes.
- 2
Air sealing of all accessible leaks. We seal top plates where interior walls meet the attic floor, electrical and plumbing penetrations, can light housings, chimney chases, and dropped soffits with fire-rated caulk, foam, and rigid blocking. This is not optional and not an upsell. Blowing insulation over an unsealed attic floor traps air leaks beneath the new material and wastes your investment.
- 3
Insulation installation to specified depth and density. Our crews use commercial blowing machines calibrated to manufacturer specs for the material chosen. We install attic rulers every 300 square feet, photograph coverage and depth at multiple angles, and verify no gaps around HVAC platforms or storage decks. Dense-pack wall work gets infrared verification before patch closure.
- 4
Blower-door testing and documentation. On jobs where air sealing was performed, we run the blower-door test again and publish the before-and-after CFM50 reading in your job record. This single number shows, in measurable terms, how much less conditioned air your home is losing. The Documented Photo Record includes attic photos, material depth verification, and the blower-door report.
- 5
Written completion record and 365-Day Done Right Promise. You receive the final documentation package before our crew leaves: photos, test results, material specifications, and warranty terms. If anything isn’t right within 365 days, we make it right. The Haven Standard means you know what leaving looks like before we arrive.
How Much Does Blown-In Insulation Cost in Burbank?
Most Blown-In Insulation pricing jobs in Burbank fall between these ranges:
- Attic top-up over viable existing insulation: $1,800-$3,400
- Attic replacement with removal of old material: $3,200-$6,500
- New blown-in to full R-38/R-49 in previously uninsulated attic: $2,800-$5,800
- Dense-pack wall insulation per 1,000 square feet of wall area: $2,400-$4,200
- Air sealing package (required before insulation on most Burbank homes): $1,200-$2,800
What moves you within these ranges: attic square footage, current insulation condition, accessibility (steep pitches and truss-framed attics take longer), and whether air sealing is included. Homes in the Burbank hills with complex rooflines and multiple HVAC platforms trend toward the higher end. Homes with straightforward gable roofs and clear attic floors trend lower.
How to avoid overpaying: get a written scope that specifies material brand, installed R-value, air sealing details, and whether removal is included. Vague quotes with per-bag pricing often underestimate the material needed. Our written price is flat and final; the number doesn’t change unless you change the scope. We also offer a Free Second Opinion on any written estimate from another contractor. Bring us their scope and we’ll read it with you, line by line, at no charge.
What’s included in our free estimate: attic inspection, insulation depth measurement, infrared scan for thermal bypasses, blower-door test when accessible, and a written price valid for 30 days. Call (213) 816-1699 to schedule. Estimates are free and no-obligation.

Frequently Asked Questions - Blown-In Insulation in Burbank

Blown-in insulation is loose-fill fiberglass or cellulose material installed with a blowing machine to achieve consistent depth and coverage in attics and wall cavities. Unlike batt insulation that comes in pre-cut rectangles, blown-in material conforms to irregular spaces and fills around obstructions like wiring and ductwork. In Burbank, it’s the standard method for adding R-value to existing homes without removing drywall or roof sheathing.
Most attic jobs in Burbank take one day; dense-pack wall work takes one to two days depending on access method and square footage. Air sealing adds 2-4 hours but happens concurrently with prep work, not as a separate visit. You’ll receive a specific time estimate in your written scope before work starts. Call (213) 816-1699 for a timeline based on your home’s specifics.
Typical attic jobs run $2,400-$5,800 installed, with top-up work starting around $1,800 and full removal-and-replacement reaching $6,500 for larger homes. Dense-pack walls average $2,400-$4,200 per 1,000 square feet. Every quote from Topside Attic Insulation Burbank is a flat written price delivered before any work begins. Call (213) 816-1699 for your exact number.
Yes. We install Owens Corning AttiCat fiberglass, Johns Manville Climate Pro fiberglass, and multiple cellulose systems including Knauf EcoFill and GreenFiber All Borate. We don’t claim exclusive status with any manufacturer, which means we recommend the material that fits your performance goals and budget, not the one we’re pushed to sell. Your written scope names the exact product and quantity.
We answer calls 24/7 and can often respond same-day to urgent comfort problems, especially when HVAC contractors have identified the attic as the root cause. True insulation emergencies are rare, but we treat extreme temperature splits, post-rodent contamination, and failed inspections with priority scheduling. A live person answers at (213) 816-1699, never voicemail.
All completed work is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. The specific warranty terms for materials and labor are written and delivered before work starts under Haven Standard Clause 1. Material warranties from Owens Corning, Johns Manville, Knauf, or GreenFiber apply in addition to our workmanship guarantee.
Clear attic storage items from the work area and provide access to electrical panels and attic hatches. We’ll cover floors and furniture with drop cloths, but removing fragile items from the attic itself saves time and reduces risk. For dense-pack wall work, move furniture 3 feet from exterior walls. We’ll confirm specific prep in your written scope after the initial inspection. Call (213) 816-1699 to schedule that inspection.
