If you’re fighting uneven temperatures in a mid-century ranch off Foothill Boulevard or a cabin-style home near Tujunga Canyon Road, call (855) 362-0195 for a free estimate. We know these houses, we know this canyon, and we know what foam belongs where.
Our work here isn’t the same as a job in Burbank. Tujunga sits in a canyon corridor at the base of the San Gabriels, and that changes everything about how a spray foam job should be scoped. We plan for radiant heat on south-facing walls, cold night drafts, detached workshops, and ember intrusion from wildfire season. One trip, done right.
Why Even Air Insulation Is Tujunga’s Preferred Spray Foam Insulation Company
We work throughout Tujunga, from the streets west of Sunland Boulevard up to the canyon mouths along Big Tujunga Canyon Road. The houses here aren’t like the stucco boxes on the valley floor. We see 1920s cabins, 1950s ranch homes, and acreage properties with detached workshops and oversized garage doors. Our crews know how to work around early romex wiring, unlined attics, and vented crawlspaces that most insulation contractors never think about until they’re standing in one.
Nelson Quirarte built Even Air Insulation around one idea: prescribe the right material for the actual space, not the product that’s easiest to install. That matters in Tujunga because a single house here can need three different insulation approaches at once. Closed-cell foam on a south-facing wall, open-cell in the attic, and air-sealing at the rim joists. Most contractors push one product. We carry eight brands and we’re trained in three installation methods, so the recommendation you get is the one that fits your house.
Homeowners call us because the recommendation feels honest. We’ve told Tujunga residents that spray foam isn’t the right choice for their particular retrofit, and we’ve walked them through what is. That’s why people along Hillrose Street and west of Mount Gleason Avenue keep referring us to neighbors.
Spray Foam Attic Insulation in Tujunga
Spray foam attic insulation in Tujunga is the highest-return upgrade most of these canyon homes can make, but it has to be scoped for the local conditions. Many attics here are unlined, or lined with old wiring that can’t sit under thick foam without trapping heat against it. A typical attic spray foam job in Tujunga runs $2,800 to $7,500 depending on square footage and whether we’re sealing the roofline or the attic floor.
Ember-Resistant Sealing
After the 2007 and 2020 fire seasons, a lot of Tujunga homeowners started asking about ember intrusion, not just heat. We seal soffit vents and close the gaps where wind-driven embers slip into the attic during Santa Ana events. That’s not a standard part of a valley-floor spray foam quote, but it should be here.
Open-Cell vs Closed-Cell
For most Tujunga attics, open-cell foam makes sense. It’s lighter, it moves with old framing, and it air-seals well. But when an attic doubles as a storage space or sits directly under a south-facing roof deck, we’ll recommend closed-cell Demilec or Icynene for the structural rigidity and higher R-value per inch.
Spray Foam Wall Insulation in Tujunga
Spray foam wall insulation in Tujunga is where we spend a lot of time on retrofit work. Mid-century ranch homes and cabin-style builds from the 1920s through the 1960s often have zero cavity insulation. That means a south-facing wall can bake all afternoon and radiate heat into the house until midnight. Wall spray foam jobs here typically run $3,500 to $9,000 for a full exterior wall retrofit, with closed-cell foam on the upper end because of its vapor and structural properties.
Radiant Heat Management
The canyon geography means Tujunga homes pull double duty. South and west slopes get brutal afternoon sun, then the temperature drops hard after dark. Closed-cell foam on those walls slows both the heat gain and the heat loss. It’s a radiant-swing problem, not a heating-degree-day problem, and the foam choice has to reflect that.
Whole-Property Scoping
We scope Tujunga jobs as whole properties, not single rooms. That means the detached workshop, the garage ceiling, and the rim joists get evaluated at the same visit as the main house. When a property has an uninsulated outbuilding, it’s a heat sink the main house has to fight. Foaming the workshop walls while we’re already on site costs less than a second trip later.
Trusted Brands We Service in Tujunga
Even Air Insulation carries a curated roster of eight manufacturers, and for Tujunga work we lean on a few more than others. Demilec and Icynene cover our spray foam line, with both open-cell and closed-cell formulations available. For homes where spray foam isn’t the right call, GreenFiber gives us a recycled-content blown-in option that fits certain unlined attics better, and Owens Corning and Johns Manville cover traditional batt work where it belongs. We don’t stock one product and push it everywhere. The job dictates the material. If you’re near Tujunga Canyon Road or up around the 91043 zip, we can get the right product to your house quickly.
Common Spray Foam Insulation Problems We See in Tujunga Homes
- Canyon cold bypassing the foam. Homes with vented crawlspaces and open soffit vents get foam installed, but cold San Gabriel night air still moves through the floor and attic gaps. The foam isn’t failing; the air-sealing was never addressed. We seal rim joists and soffit openings before foam goes in.
- Thick open-cell foam over old wiring. Unlined 1920s-1960s attics with knob-and-tube or early romex can’t take thick open-cell foam without trapping heat against the wires. The fix is a different material or a wiring assessment first. We flag this on nearly every older Tujunga retrofit.
- Detached workshops left untouched. One-trip jobs that skip the outbuilding leave a massive uninsulated wall area. The workshop becomes a heat sink in summer and a cold box in winter, and the main house HVAC system keeps fighting it. We include outbuildings in every Tujunga quote.
- South-wall foam without the attic seal. We see foam sprayed on a south-facing wall while the attic above it stays unsealed. The wall performance improves, but afternoon heat still pours through the attic floor. The job has to be scoped as a system, not a single surface.

FAQs About Spray Foam Insulation in Tujunga
Because Tujunga sits in a canyon corridor where Santa Ana winds drive fire embers into attic spaces through soffit vents and small gaps. Sealing those openings is part of a proper spray foam job here, not an add-on. If you’re in a fire-prone zone near Tujunga Canyon Road or the washes, ask specifically about ember-resistant sealing when you call. Call (855) 362-0195 for an exact assessment of your attic openings.
Yes, and we scope every Tujunga quote that way. Detached workshops, garages, and outbuildings are part of the property’s thermal envelope. Foaming the workshop walls while we’re on site costs less than a return trip, and it stops the outbuilding from acting as a heat sink. Our crews carry enough material for whole-property jobs, so one visit usually covers it.
Cold air from the San Gabriels slides down through the canyon at night and gets pulled into vented crawlspaces, then up through floor assemblies. If we don’t seal the rim joists and crawlspace vents before foaming the walls or attic, the cold bypasses the foam entirely. We address the air-sealing side on every Tujunga job, not just the foam itself.
Usually not thick open-cell foam, and here’s why: knob-and-tube and old romex can overheat when buried under heavy insulation. We assess the wiring first, then recommend either a lighter open-cell application, a blown-in product like GreenFiber where appropriate, or a wiring upgrade before foam goes in. The right answer depends on the attic. Call (855) 362-0195 for an honest read on your house.
Yes. South-facing and west-facing walls in Tujunga take hours of direct afternoon sun, and closed-cell foam slows that heat gain dramatically. The same walls then hold heat at night when canyon temperatures drop. Closed-cell handles both sides of that swing better than any other retrofit option in this market.
