Attic Insulation Replacement in Burbank, CA
Our Attic Insulation services for replacement in Burbank typically runs between $1,800 and $4,500 for a standard single-story home, depending on square footage, existing material, and the condition of the attic floor beneath. Most jobs are completed in a single day. If your energy bills have climbed without explanation, or if the insulation up there is packed flat, contaminated, or simply old enough to have lost its thermal resistance, replacement is almost always the right call – not a patch job on top of what’s failing.
We’re Topside Attic Insulation Burbank, operating under The Haven Standard since 2016. Wes Okafor leads every project with the same sequence: written price before any work starts, air sealing before any insulation goes in, and a documented photo record plus blower-door readings when we leave. That sequence isn’t a selling point – it’s the only way to know the replacement actually worked. You can reach us directly at (213) 816-1699 to schedule a no-cost assessment.
This page covers full attic insulation replacement specifically. If you want a broader look at the service line – R-value targets, material comparisons, and what a first-time attic assessment looks like – our Attic Insulation in Burbank page covers that ground.
When You Need Attic Insulation Replacement
There’s a difference between insulation that’s aging and insulation that has stopped doing its job. These are the scenarios where replacement is the right answer, not just a Attic Insulation Top-Up or an add-on layer:
- Insulation that’s been flattened or compressed over time. Blown-in cellulose and fiberglass both settle. When the depth gauge shows the material has lost 40% or more of its original loft, its R-value has dropped proportionally. In older Burbank homes – particularly the post-war ranch and bungalow stock in Magnolia Park and Toluca Woods – we routinely find original insulation from the 1970s sitting at an effective R-8 or lower where R-38 is the current California Title 24 minimum for attics.
- Rodent or pest contamination. Burbank’s proximity to the Verdugo Mountains and the dry brush corridor along the foothills means roof rats and squirrels are a recurring attic problem. Contaminated insulation – soiled with urine, feces, or nesting material – can’t be salvaged with spot treatment. The material comes out entirely before any rodent-proofing or re-insulation begins.
- Water intrusion or mold. A roof leak that goes unnoticed for one rainy season can saturate insulation enough to trigger mold growth in Burbank’s otherwise dry climate. Wet cellulose in particular mats down and holds moisture against wood framing. Replacement is required; drying it out is not an option once the material is compromised.
- Vermiculite or other hazardous legacy material. Some homes built before 1980 in neighborhoods like Burbank’s Rancho and Olive area have vermiculite attic insulation, which may contain asbestos-bearing mineral. This requires certified abatement before any new insulation work proceeds – something we coordinate and document before a single bag of new material comes into the home.
- Post-renovation air-sealing failure. Recessed lighting added during kitchen or bathroom renovations often punches can lights through the ceiling plane. If insulation was blown over those unsealed penetrations, the thermal performance on paper bears no relationship to what the home is actually experiencing. Replacement – paired with proper air sealing – addresses the root cause.
- Energy bills that don’t respond to HVAC tuning. If you’ve had the system serviced, replaced the filter, and checked the ducts, and your summer cooling bills in Burbank still spike past $350-$400 for a 1,600 square foot home, the attic is almost always where the loss is happening. A blower-door reading before we start will confirm it.
Our Attic Insulation Replacement Process

We run the same sequence on every replacement job. The order isn’t negotiable – specifically because blowing insulation over an unsealed attic floor is one of the most common and expensive mistakes in this industry. Here’s what the process looks like from first visit to final report:
- Pre-work blower-door test and written scope. Before any material moves, we run a blower-door test – a pressurized measurement of how much conditioned air the home’s building envelope is losing, expressed in CFM50 (cubic feet per minute at 50 pascals of pressure). This gives us a baseline number we can compare against when the job is done. The written scope, flat price, and warranty are delivered at the same appointment. Under Haven Standard Clause 1, no work starts without a written price in hand.
- Complete removal of existing insulation. We use commercial-grade vacuum equipment to extract the old material – blown-in cellulose, fiberglass batts, or whatever combination is up there – down to the attic deck. All removed material is bagged and hauled off the property the same day. If contamination is present, removal follows containment protocol. The attic floor is documented with photos before and after this step.
- Air sealing of the attic floor – every penetration, every plate. This is the step most contractors skip or treat as optional. We seal top plates (the framing where interior walls meet the ceiling plane), recessed can lights, plumbing and electrical penetrations, and any attic bypasses using fire-rated foam and mastic. This step is completed and documented before any new insulation enters the space. In Burbank homes with older can-light fixtures in living areas – common in the mid-century stock in Burbank Hills and the Rancho district – this step alone can account for the majority of the air-sealing gain.
- Installation of new insulation to current California Title 24 standards. We install to a minimum R-38, which is the current code requirement for attics in California’s Climate Zone 9 (where Burbank sits). Most replacement jobs we do land between R-38 and R-49 depending on the home’s cooling load and the customer’s goals. Material is sourced from Owens Corning or Johns Manville blown-in fiberglass, or GreenFiber cellulose, depending on the application – no proprietary product lock-in. Depth rods are installed so you can verify the settled depth at any time without entering the attic.
- Post-work blower-door test. Once insulation is in and the attic access is resealed, we run a second blower-door reading. The before-and-after numbers go into your documented report – not summarized, not paraphrased, but the actual CFM50 figures. A representative job we completed in Magnolia Park in early 2025 read 3,800 CFM50 before sealing and 1,950 CFM50 after, with new blown-in fiberglass to R-49. Those numbers tell you what you actually paid for.
- Documented photo record and written warranty delivered. You receive a full photo record – attic deck before removal, air sealing in progress, depth rods post-installation, and final condition – along with the blower-door report and your written 365-Day Done Right Promise. If anything isn’t right within that window, we come back and make it right. That’s written, not verbal.

AfterAttic Insulation Replacement Pricing in Burbank
Most attic insulation replacement jobs in Burbank fall in the range below. These are real numbers based on work we’ve done across the city – not national averages adjusted with a multiplier.
| Scope | Typical Range |
|---|---|
| Removal only (vacuum extraction + haul-off), 1,000-1,400 sq ft attic floor | $600 – $1,100 |
| Air sealing (top plates, can lights, penetrations), standard attic | $400 – $900 |
| New blown-in insulation to R-38, 1,000-1,400 sq ft | $900 – $1,600 |
| New blown-in insulation to R-49, 1,000-1,400 sq ft | $1,100 – $1,900 |
| Full replacement (removal + air sealing + R-38 reinstall), 1,000-1,400 sq ft | $1,800 – $3,200 |
| Full replacement (removal + air sealing + R-49 reinstall), 1,400-2,200 sq ft | $2,800 – $4,500 |
| Contaminated insulation removal (rodent or mold – with containment protocol) | Add $300 – $700 |
What moves the price
- Attic access difficulty. Burbank’s mid-century homes often have low-pitch rooflines and attic hatches positioned over closets or hallways. Tight access adds time to both the removal and installation steps.
- Number of can lights and penetrations. A kitchen remodel that added a grid of recessed lights can mean 20 or more unsealed penetrations. Each one takes time to seal correctly.
- Contamination level. Standard settled insulation removal is straightforward. Rodent-contaminated material requires containment, PPE, and disposal as regulated waste – that adds cost and is non-negotiable for occupant health.
- Target R-value. Going from R-38 to R-49 is not double the material – it’s roughly 30% more depth. The incremental cost is modest relative to the long-term performance gain, particularly in Burbank where attic temperatures regularly reach 140-160°F on summer afternoons.
Under Haven Standard Clause 1, you receive a flat written price before any work starts. There are no line items that appear after the job is done.

FAQs – Attic Insulation Replacement

How long does attic insulation replacement take in Burbank?
A full replacement – removal, air sealing, and reinstallation – on a standard Burbank home in the 1,200 to 1,800 square foot range typically takes one full day, occasionally two if the attic has significant contamination or a large number of penetrations to seal. We schedule a specific technician to your job, and you receive a text when they’re on the way – no arrival windows measured in half-days. Call (213) 816-1699 to get a time estimate specific to your attic’s footprint.
Do I need to replace insulation, or can I just add more on top?
Adding a new layer on top of existing insulation only makes sense when the material underneath is clean, dry, structurally intact, and the attic floor has already been properly air-sealed. If the existing material is contaminated, water-damaged, heavily settled, or was installed over an unsealed attic floor, adding on top doesn’t fix the underlying problem – it buries it. We assess the condition of the existing material before making any recommendation, and we’ll tell you plainly what we find rather than defaulting to the higher-ticket option. Schedule a free assessment by calling (213) 816-1699.
Is attic insulation replacement required by California code when I sell my home?
California law requires attic insulation to meet a minimum of R-38 at point of sale for most residential properties – this is enforced through the state’s Title 24 compliance requirement. A home inspector will flag sub-standard insulation depth in a buyer’s inspection report, and it commonly becomes a repair item in escrow. Replacing before you list avoids the negotiation and the compressed timeline. If you’re in that situation in Burbank, we can schedule quickly and deliver the written documentation your escrow officer needs. Call (213) 816-1699 to talk through the timeline.
What insulation material do you use for replacement in Burbank’s climate?
For most Burbank attics, we install Blown-In Attic Insulation using fiberglass from Owens Corning or Johns Manville, or blown-in cellulose from GreenFiber – the choice depends on the attic configuration, existing conditions, and the homeowner’s preference. Blown-in fiberglass settles less than cellulose over time and performs well in Burbank’s dry heat. Cellulose has a higher recycled content and slightly better air resistance at equivalent depth. We don’t use a proprietary product line, so the recommendation is based on what performs best for the application, not on what we’re committed to moving. Either way, installation is to California Title 24 minimum R-38, with R-49 available for homeowners targeting stronger performance during Burbank’s peak summer heat.
Why Topside Attic Insulation Burbank
Since 2016, we’ve completed work in over 9,000 homes across the region – every one with a written price before work started and a documented photo record when the crew left. Wes Okafor built the company around the principle that insulation performance should be measurable, not claimed. That’s why every applicable job includes before-and-after blower-door readings: a CFM50 number before we touch the attic, and a CFM50 number after we seal and insulate it. You don’t have to take our word for the improvement – the numbers are in your file.
We work across Burbank – from Magnolia Park and Toluca Woods to the Burbank Hills, the Rancho district, and neighborhoods closer to the studios along Olive Avenue. The attic conditions vary considerably: older ranch homes with decades-old cellulose, mid-century properties with can lights punched through unblocked ceiling planes, and newer construction where the insulation was installed fast and the air sealing was skipped entirely. We’ve seen all of it, and we know what the documentation looks like when the job is done correctly.
