Trusted Spray Foam Insulation for Burbank Homeowners
Spray Foam Insulation in Burbank typically costs $2.80-$6.50 per board foot installed, with most residential projects running $3,200-$8,500 depending on whether you need open-cell or closed-cell material and how accessible the space is. Most jobs are completed in one to two days, and we can often start within a week of your estimate. Call (213) 816-1699 to schedule a free written estimate with a flat price before any work begins.
We’ve sealed and insulated over 9,000 homes since 2016, and we’ve learned that spray foam fails when it’s applied over an unsealed surface. That’s why every spray foam job we do in Burbank starts with air sealing - top plates, can lights, plumbing and electrical penetrations - before the first board foot goes in. We publish before-and-after blower-door numbers on every applicable job, so you see the actual performance change in CFM50, not just a promise. Burbank’s mix of 1940s bungalows in the Rancho area, mid-century ranches near the studios, and newer construction in the hills each presents different envelope challenges, and we’ve worked on all of them. Our crews are background-checked, uniformed, and arrive with a written scope, written warranty, and documented photo record - every time, no exceptions.
What Our Spray Foam Insulation Service Includes
Open-Cell Spray Foam
Open-cell spray foam is a lightweight, vapor-permeable insulation - it expands to roughly 100 times its liquid volume and cures to a spongy, flexible material that fills irregular cavities completely. In Burbank, we use it most often in attic floors and non-vented roof assemblies where moisture needs to be able to dry to the interior, which matters because our hot, dry summers can drive moisture inward through the envelope. At Topside Attic Insulation Burbank, we never install open-cell without first sealing the attic floor with caulk and foam at every top plate and penetration; we’ve seen too many jobs where foam was sprayed over a leaky ceiling and the homeowner got an R-value upgrade with no actual air-leakage reduction.

Closed-Cell Spray Foam
Closed-cell spray foam is denser, rigid, and vapor-closed - it adds structural rigidity and delivers R-6.5 to R-7 per inch, roughly double what open-cell provides. We specify it in Burbank for garage ceilings, rim joists, and any application where space is limited and maximum R-value per inch matters, such as the tight crawl spaces common in the older homes near Magnolia Park. Our crews apply it in lifts of no more than 2 inches to prevent exothermic reaction issues, and we verify thickness with a pin probe on every job. The material we use is sourced from Owens Corning and Johns Manville formulations - no proprietary lock-in, so if you have a preference, we’ll accommodate it.

Rim Joist Spray Foam
The rim joist - the perimeter band where your foundation meets your first floor - is often the leakiest part of a home’s thermal boundary, and it’s almost never insulated in Burbank’s older stock. We seal rim joists with closed-cell spray foam because the combination of wood, concrete, and steel in that assembly creates expansion and contraction cycles that batts can’t accommodate. In homes we’ve worked on near the Burbank Hills, rim joist sealing alone has dropped blower-door readings by 800-1,200 CFM50. We spray the full cavity, including the sill plate joint, and we photograph every bay before and after for your documented record.

Garage Ceiling Spray Foam
Garage ceilings in Burbank are a common thermal bridge - they’re often uninsulated drywall or open joists separating a conditioned room above from a space that hits 110°F in August. We spray closed-cell foam on garage ceilings when the floor above is living space, which eliminates both conductive heat gain and air leakage from the garage into the home. In the hills above Glenoaks, where wildfire ember exposure is a concern, the air-sealing benefit matters even more: a sealed garage ceiling reduces the stack effect that can pull embers into the structure. We mask and protect everything below, and we coordinate with your schedule because the garage is unusable for 24 hours after application.

Spray Foam Roof Deck
Spray foam applied directly to the underside of the roof deck creates an unvented, conditioned attic - the hot roof assembly that works well in Burbank’s climate because it keeps ductwork inside the thermal envelope. We only do this after verifying that the existing roof ventilation can be eliminated or converted, and after sealing every ceiling penetration from below. The foam acts as both insulation and air barrier, and in homes we’ve completed near Verdugo Avenue, summer attic temperatures dropped from 140°F to within 10°F of the living space. We specify open-cell for most roof deck applications in Burbank and closed-cell only where roof deck condensation risk is elevated, such as homes with pool equipment in the attic or unusual humidity loads.

Brands We Service for Spray Foam Insulation

We source spray foam materials from Owens Corning, Johns Manville, Knauf, and other major manufacturers - no proprietary product lock-in, so we specify based on what your assembly needs, not what we’re obligated to sell. Owens Corning’s FOAMULAR and similar closed-cell formulations have been our go-to for garage ceilings and rim joists in Burbank for years; we know their cure times, adhesion characteristics, and how they perform in our dry heat. Johns Manville’s open-cell products have given us consistent results in attic floor and roof deck applications, particularly in the older homes near the Media District where irregular framing demands material that can fill complex geometries without voids.
Knauf’s spray foam line has become our preference for certain high-R-value applications where board-foot cost and performance need to balance precisely. We’ve applied thousands of sets across these brands, and we track lot numbers and application conditions for every job. Whether your architect specified a particular product or you have no preference and want us to recommend based on your blower-door results and budget, we can accommodate. If you’re comparing estimates, bring us any written quote - our Free Second Opinion means we’ll read it with you line by line and explain where the specifications differ.
Before
AfterSigns You Need Spray Foam Insulation Right Now
- Your upstairs rooms are 10-15°F hotter than downstairs in July. This temperature stratification usually means your attic is venting conditioned air faster than your HVAC can replace it. In Burbank, where summer afternoons hit 95°F regularly, an unsealed attic floor acts like a chimney pulling cool air up and out. Spray foam, applied after proper air sealing, stops that stack effect.
- You can see your insulation batts lying flat or pulled away from the eaves. When batts compress or fall, they’re doing almost nothing. We’ve found this in half the 1950s-1970s homes we inspect in Burbank, especially near the hillside where wind exposure accelerates degradation. Spray foam adheres to the substrate and won’t settle or shift.
- Your energy bills spike every August despite a new HVAC system. A new air conditioner can’t fix an envelope that leaks. If your blower-door number is above 3,500 CFM50 for a 2,000-square-foot home, your conditioned air is leaving faster than mechanical efficiency can compensate. Spray foam insulation, properly specified and installed after air sealing, addresses the root cause.
- You feel drafts near outlets, baseboards, or attic hatches even with windows closed. These are telltale signs of pressure-driven air leakage through the thermal boundary. In Burbank’s older neighborhoods, top plates and partition walls are rarely sealed during original construction. Spray foam at the attic floor level can seal these pathways permanently.
- You’re finishing an attic, garage, or addition and the building department requires insulation compliance. Burbank Building and Safety enforces Title 24 energy standards strictly, and spray foam often provides the most straightforward path to compliance in retrofit or addition scenarios where cavity depth is limited. We provide the documentation and ICC-ESR reports your inspector will ask for.
Our Spray Foam Insulation Process - Step by Step

- 1
On-site assessment and blower-door test. We arrive at your Burbank home with a written appointment time, a named technician, and a text when we’re en route. The first step is a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. We record CFM50 before any work begins, and we photograph every relevant surface: attic floor, roof deck, rim joists, garage ceiling, whatever we’re treating.
- 2
Written scope, written price, written warranty. Under Haven Standard Clause 1, no work starts without a flat price in writing. Your scope specifies every assembly to be treated, the material type and thickness, the targeted R-value, and the post-work blower-door target. The 365-Day Done Right Promise is included in writing before anyone lifts a tool.
- 3
Air sealing before insulation. This is the step that separates our work from standard spray foam jobs. We seal top plates with acoustic sealant and expanding foam, box out can lights with fire-rated covers, foam every wire and pipe penetration, and address any chimney or flue gaps with appropriate materials. In Burbank homes with original knob-and-tube wiring still active, we flag it and coordinate with your electrician - we don’t bury live KT in foam.
- 4
Spray foam application with thickness verification. Our crews apply foam in controlled lifts, monitoring substrate temperature and humidity to ensure proper adhesion and cure. We probe-check thickness at minimum six points per 1,000 square feet, and we photograph the completed application from multiple angles. The lot numbers of every set we spray are recorded in your job file.
- 5
Post-work blower-door test, documentation delivery, and walkthrough. After the foam cures, we run the blower door again and compare to your baseline. You receive the before-and-after CFM50 reading, the thickness probe log, the complete photo record, and your written warranty. We walk through the findings with you on site or by video call, and we leave only when you understand what was done and what performance changed.
How Much Does Spray Foam Insulation Cost in Burbank?
A typical open-cell spray foam attic floor in a 1,200-1,800 square foot Burbank home runs $3,200-$5,800, while closed-cell applications in the same footprint range $4,800-$8,200 because of the higher material density and slower application rate - learn more about how much Spray Foam Insulation costs for your specific project. Rim joist sealing for a full perimeter typically falls between $1,800-$3,400. Garage ceiling spray foam in a standard two-car footprint runs $2,400-$4,200, and roof deck applications - the most material-intensive - range $5,500-$11,000 depending on pitch complexity and whether we need to remove existing ventilation baffles.
Several factors move these numbers. Access is the big one: a trussed attic with a hatch in a hallway takes more labor than a walk-up with permanent stairs. Existing insulation removal adds $1.00-$2.20 per square foot. Roof deck work on a steep pitch, common in the Burbank Hills, requires scaffolding or specialized fall protection that flat-attic jobs don’t. And the condition of your existing air barrier matters - homes with extensive top plate gaps or unsealed recessed lights need more prep time before foam goes in.
The most common way homeowners overpay is accepting a per-board-foot quote without a written scope specifying minimum thickness and coverage area. We’ve reviewed competitors’ estimates where “2 inches average” meant 1.5 inches at the eaves and 2.5 at the center - acceptable on paper, inadequate in practice. Our written scope specifies minimum thickness at every point, not average, and we verify with probes. Every free estimate includes a flat price for the complete job, not a rate that balloons if we find “unexpected conditions.” Call (213) 816-1699 for your written estimate - there’s no obligation, and our Free Second Opinion applies to any competing quote you’ve already received.

Frequently Asked Questions - Spray Foam Insulation in Burbank

Spray foam insulation is a two-component chemical mixture that expands on contact to fill cavities, gaps, and irregular surfaces, then cures to a rigid or semi-rigid foam that provides both thermal resistance and an air barrier in one application. Unlike fiberglass batts, which leave gaps at edges and compress over time, or blown-in cellulose, which can settle and requires a separate air barrier, spray foam adheres to substrates and maintains its R-value for the life of the building. In Burbank’s climate, where summer attic temperatures exceed 140°F, the air-sealing benefit often matters more than the nominal R-value improvement.
Most residential spray foam jobs in Burbank are completed in one to two working days, with an additional 24-hour cure period before the space can be occupied or used for storage. Attic floor applications on a 1,500-square-foot home typically take 6-8 hours of crew time; roof deck work on a complex pitch may extend to two days. We schedule start times to minimize disruption, and our crew leaves the work area clean and documented with photos before they depart. Call (213) 816-1699 to check our current schedule - we can usually start within a week of estimate approval.
Open-cell spray foam installed in a typical Burbank attic runs $2.80-$4.20 per board foot, while closed-cell ranges $4.50-$6.50 per board foot, with most whole-home projects falling between $3,200 and $8,500 depending on assembly type and accessibility. Rim joist sealing is typically the least expensive application at $1,800-$3,400; roof deck work is the most material-intensive and ranges $5,500-$11,000. Your written estimate from Topside Attic Insulation Burbank specifies a flat price for the complete scope - no per-board-foot rates that shift if we find more area than estimated. Call (213) 816-1699 for an exact quote; estimates are free and include our Free Second Opinion on any competing bid.
Yes - we source and apply spray foam materials from Owens Corning, Johns Manville, Knauf, and other major manufacturers, and we have direct experience with the specific formulations each produces for Southern California climate zones. We don’t carry proprietary products or exclusive lines, so if your architect or energy consultant specified a particular brand, we can accommodate. Every set we install is tracked by lot number and documented in your job record for warranty purposes.
We answer calls 24/7 through a live person, not voicemail, and we can dispatch for urgent situations such as insulation failure after a roof leak, rodent contamination requiring removal and replacement, or building department corrections with deadlines. Same-day response is available for Burbank addresses depending on crew location; we typically confirm an arrival window within 30 minutes of your call. For true emergencies - such as a compromised thermal envelope with an infant or elderly resident in the home - we prioritize dispatch. Call (213) 816-1699 and we’ll tell you honestly whether we can be there today or whether first-available is tomorrow.
Every spray foam job is backed by our 365-Day Done Right Promise - if it’s not done right, we make it right - plus the manufacturer’s material warranty, which typically covers degradation or adhesion failure for the lifetime of the building. The Haven Standard requires that both warranties are delivered in writing before work begins, and your documented photo record provides the baseline evidence if any issue arises. In nine years and 9,000 homes, warranty claims on our spray foam work have been rare because we don’t skip the air-sealing step that prevents the moisture and condensation issues that cause foam failure.
Clear the attic or target area of stored items at least 48 hours before our arrival; we can coordinate this as part of the job if needed, but it affects scheduling and price. Ensure we have driveway or street parking for our rig - the spray foam trailer requires level ground within 150 feet of the access point. For attic work, we need the attic hatch or scuttle clear and a path through the home that protects your floors; our crews use drop cloths and shoe covers, but narrow hallways with fragile items need your attention. Pets should be removed from the home during application and for 24 hours after, as the curing process produces isocyanate vapors that dissipate with ventilation but can sensitize animals. We’ll provide a written prep checklist with your scope so nothing is missed.
