Trusted Spray Foam Insulation for Burbank Homeowners
Spray foam insulation in Burbank typically costs between $2.50 and $6.50 per board foot installed, with most whole-attic projects landing between $3,500 and $9,000 depending on foam type and square footage. Our team at Warmline Insulation Co. has installed open-cell and closed-cell foam in hundreds of Burbank homes since 2011, cutting energy bills by 30-50% in many cases. If you’re fighting a hot upstairs, a drafty rim joist, or a garage that turns into an oven by noon, call (747) 837-5834 and you’ll get Neil Ashford or another Warmline team member on the line, not a voicemail. We’re home performance specialists, not generalists, and we’ll tell you straight whether spray foam is the right tool for your house or whether another material would serve you better.
What Our Spray Foam Insulation Service Includes
Spray foam isn’t one product. It’s a family of materials applied differently depending on where you’re putting it and what problem you’re trying to solve. Here’s exactly what we do under the spray foam umbrella.
Open-Cell Spray Foam
Open-cell foam is the half-pound-density option that expands dramatically on application, filling stud bays and rafter cavities with a spongy, air-sealing blanket. In Burbank’s Mediterranean climate, we most often recommend open-cell for attic roof decks and interior wall cavities where you want sound dampening plus a strong air barrier without the added cost of closed-cell density. Warmline crews apply it to the correct depth for your framing depth, and we verify coverage with thermal imaging before we pack up. It’s the go-to when your priority is whole-house air sealing at a sensible price.
Closed-Cell Spray Foam
Closed-cell foam cures rigid and dense, around two pounds per cubic foot, and it adds structural strength along with an R-value of roughly 6.5 to 7 per inch. We specify closed-cell in Burbank crawl spaces, unvented attics where space is tight, and anywhere moisture intrusion is a concern, because the cured foam acts as a Class II vapor retarder. On older Burbank homes with 2×4 walls, a flash-and-batt detail using closed-cell plus fiberglass gets you big performance in a thin cavity. It costs more than open-cell, which is why we’ll always show you the numbers for both before you commit.
Rim Joist Spray Foam
The rim joist, the band of framing where your floor meets your foundation, is one of the leakiest parts of most Burbank homes. We spray closed-cell foam into each rim joist bay to stop outside air from slipping into your floor system and rodent activity from following the gaps. A typical two-story Burbank house has 25 to 40 rim joist bays, and we can usually finish the whole job in three to five hours. Homeowners are often surprised at how much warmer their floors feel the next morning.
Garage Ceiling Spray Foam
Attached garages in Burbank routinely hit 110°F in summer, and that heat bleeds straight into the bedrooms above them. We apply closed-cell or open-cell foam to the garage ceiling, creating a thermal break that keeps the garage’s heat where it belongs, out of your living space. If the garage is below a bonus room or a primary suite, this is one of the highest-return spots in the house. We’ll also air-seal the shared wall between garage and living space while we’re in there.
Spray Foam Roof Deck
In Burbank, where many homes have unvented attic assemblies or vaulted ceilings, spraying the underside of the roof deck turns the attic into conditioned space. That means your HVAC equipment, if it lives up there, stops fighting 140°F summer air. Warmline applies foam directly to the roof sheathing, creating a monolithic air seal and insulation layer in one pass. It’s a bigger investment than blown-in attic floor insulation, but it solves multiple problems at once: duct losses, attic heat, and air leakage.

Brands We Service for Spray Foam Insulation
Warmline Insulation Co. installs spray foam from manufacturers whose chemistry has been proven over decades, not startup labs. We’re a certified installer for Icynene open-cell and closed-cell systems, and our crews apply Demilec closed-cell products regularly across Los Angeles County. These are the foams we trust in our own homes because their formulation is stable, their off-gassing window is short, and their published R-values hold up in independent testing.
We also work extensively with Owens Corning and Knauf batt and blown-in products for hybrid assemblies, like flash-and-batt details where a thin closed-cell layer pairs with fiberglass to hit code compliance at a lower price. Whether your project calls for Icynene foam, Demilec sealants, or any other proven system, our team will match the product to your specific Burbank home. We’ll never push one brand because it’s what we have on the truck, we’ll order what your house actually needs.
Signs You Need Spray Foam Insulation Right Now
Some insulation problems are slow-burn, but others are costing you real money every single month. Here’s what we see in Burbank homes that tell us spray foam is the answer.
- Your upstairs bedrooms won’t cool below 80°F in summer. Burbank summer afternoons regularly push 95°F or more, and if your second floor stays hot no matter how long the AC runs, your attic insulation or air sealing is failing. Spray foam on the roof deck or attic floor can drop those room temperatures 10-15 degrees by stopping the heat at its entry point.
- You can feel air moving around outlets, light fixtures, or baseboards. Burbank’s Santa Ana winds find every gap in your building envelope. If you feel drafts on windy days, your home’s air barrier is compromised. Spray foam is the only insulation that seals and insulates in one step, which is why we reach for it on leaky older homes.
- Utility bills climb every July and August, even though your thermostat setting hasn’t changed. Burbank Water and Power rates keep rising, but a leaky attic makes every rate increase hurt twice. We’ve documented 30-50% cooling-cost reductions after spray foam retrofits on 1960s and 1970s ranch-style homes in the hills and flats alike.
- You hear rodents or birds in the attic at dawn or dusk. Burbank’s hills mean critter pressure year-round. Gaps where roof meets wall are rodent entry points, and spray foam’s rigid structure, especially closed-cell, blocks them better than fiberglass batts. Our attic cleaning and rodent proofing team often recommends foam as the permanent fix.
- Your garage is attached and your kitchen floor above it is cold in winter. Uninsulated garage ceilings are the most overlooked heat-loss zone in Burbank homes. If your kitchen tile feels cold on January mornings, spray foam under that garage ceiling rewrites the comfort equation immediately.
Our Spray Foam Insulation Process - Step by Step
We’ve refined our process on hundreds of Burbank attics, crawl spaces, and garages since 2011. Here’s how it goes, start to finish.
- 1
Home energy audit and thermal imaging. Before we spec any foam, Neil Ashford or a senior technician walks your home with a thermal camera and a blower door when the project calls for it. We map exactly where your conditioned air is escaping and where heat is intruding. This diagnostic step is the difference between guessing and knowing, and it means you don’t pay for foam where you don’t need it.
- 2
Custom proposal with line-item pricing. You get a written quote that separates material costs, labor, and prep work. No “spray foam package” lumps. If open-cell makes more sense than closed-cell for your project, we show you both options and explain why we’d pick one over the other.
- 3
Prep and protection. Our crews cover your floors in the work zone, seal off the area with negative air pressure when spraying inside living space, and verify ventilation paths are clear. We move or mask anything the foam could possibly touch. Most Burbank homes are ready for this in under an hour.
- 4
Application to spec. We spray to the exact depth your assembly needs, not a generic “looks thick enough.” For closed-cell, that’s typically 2 to 3 inches to hit vapor-retarder performance. For open-cell roof decks, we fill the rafter cavity fully. We check thickness with depth gauges throughout the application, then scan with thermal imaging before cleanup.
- 5
Post-job verification and the 90-Day Done Right Promise. We walk you through before-and-after thermal photos, explain what changed, and leave the site cleaner than we found it. If anything isn’t right, our 90-Day Done Right Promise means we come back and make it right, in writing, at no charge. Most jobs are completed in a single visit.
How Much Does Spray Foam Insulation Cost in Burbank?
What pushes the price up? Crawlspace access without a man door, old knob-and-tube wiring that needs inspection before we spray, and attics with low pitch where our techs work on their knees. What pushes it down? Open-cell instead of closed-cell, smaller areas, and combining spray foam with other services like attic air sealing, which we can do in the same visit. We offer free estimates that include thermal imaging, so you’ll see exactly where your money is going before you spend a dollar. And keep in mind our standing offers: $50 off any repair over $250, an $89 seasonal tune-up, and a permanent 5% Senior & Veteran discount on every job.

Frequently Asked Questions - Spray Foam Insulation in Burbank
What is spray foam insulation?
Spray foam insulation is a two-part liquid polyurethane that expands on contact with air, hardening into a continuous insulation and air-sealing layer. It comes in open-cell and closed-cell variants, each suited to different parts of a Burbank home. Unlike fiberglass batts, spray foam fills every gap, crack, and void in the cavity it’s applied to, so it insulates and air-seals in one step.
How long does spray foam insulation installation take in Burbank?
Most Burbank spray foam projects finish in one day. A typical rim joist job takes three to five hours, a garage ceiling four to six hours, and a full attic roof deck one to two days depending on access and square footage. We schedule most jobs for a single visit, and our teams arrive with everything they need on the truck.
How much does spray foam insulation cost in Burbank?
Spray foam in Burbank runs $2.50 to $6.50 per board foot installed, with most homeowners spending between $3,500 and $9,000 for whole-attic projects. Rim joist work starts around $900, and garage ceilings average $1,800 to $3,200. Call (747) 837-5834 for a free estimate with thermal imaging, so you get a price based on your actual house, not a phone quote.

How do I prepare my house for spray foam installation?
Clear the attic or crawl space entrance so our team can set up, move any stored items away from the work area, and make sure pets are kept away from the application zone for the day. We handle everything else: floor protection, masking, ventilation, and cleanup. Most Burbank homeowners don’t need to do more than clear a path.
