Fast, Reliable Spray Foam Insulation Across Van Nuys
Spray foam insulation in Van Nuys is the most effective fix for the brutal attic heat gain that defines this part of the San Fernando Valley. We work throughout 91401, 91405, 91406, and 91411, and our crews know exactly what they’ll find when they open a hatch on a 1950s ranch off Van Nuys Boulevard: bare decking, ducts cooking in 140-degree air, and a wall assembly with no thermal barrier worth mentioning. The result of sealing those surfaces with closed-cell foam is immediate. Rooms stop fighting the afternoon sun, the AC doesn’t run constantly, and the temperature evens out room to room.

Why Cozy Insulation Co Is Van Nuys’s Preferred Spray Foam Insulation Company
Our Spray Foam Insulation team has spent years working in the post-war ranch tracts and stucco apartment blocks that define Van Nuys housing. That matters because the job here is rarely the same as it is in newer Valley communities. We know the low-pitch attic framing, the original single-pane windows, and the uninsulated wood-frame walls well enough to predict where heat is actually entering a structure before we pop the first canister.
Led by Mike Callahan, our crews work with Icynene and Demilec spray foam systems, the two brands we trust most on hot-side applications. Homeowners and property managers across the 914 zip codes call us because we show up with the right rig for the job, not a generic insulation crew that only wants to blow fiberglass. When a Van Nuys apartment owner needs a five-unit building sealed, we can do it without subcontracting anything out.
Crawl Space Spray Foam Insulation in Van Nuys
Crawl Space Spray Foam Insulation in Van Nuys typically runs $2,200 to $4,800 depending on square footage and access. On many of the single-story ranch homes in the 91406 and 91411 areas, the crawl space is shallow, sometimes as little as 18 inches, and lined with nothing but bare earth. Closed-cell foam applied to the subfloor and rim joists keeps the floor from radiating cold in January and stops the moist, heavy air that rises out of the earth from finding its way into the living space.
Sealing a Shallow Ranch Crawl
The older Van Nuys ranch stock often has vented crawl spaces built before modern air-sealing standards were even a consideration. Foam on the floor framing and rim joists turns that damp, drafty void into a quiet, clean buffer zone. Mike and his crew regularly see floor temperatures jump noticeably the same week the foam cures.
Why Not Batt Insulation in a Crawl Space
Fiberglass batts in a Van Nuys crawl space is a losing fight against gravity and humidity. Batts sag, absorb moisture, and host pests. Closed-cell foam adheres, insulates, and adds a structural barrier to the rim that batts simply cannot match.
Garage Spray Foam Insulation in Van Nuys
Garage Spray Foam Insulation in Van Nuys usually costs between $1,400 and $3,600. We foam a lot of garages off Van Nuys Boulevard and the numbered streets, especially the oversized roll-up door models built for workshop use or classic car storage. That big metal door is a thermal disaster. Foam on the ceiling and the wall separating the garage from the living space stops the heat from bleeding into the house through the shared wall.
Detached Workshops and Roll-Up Doors
A detached workshop in Van Nuys with an uninsulated roof deck bakes from 10 a.m. until sundown for seven months of the year. We apply closed-cell foam directly to the ceiling deck. The foam reflects the radiant load and seals the rim and gable penetrations, so a mini-split can actually hold temperature instead of running all afternoon.
Garage-to-Living-Space Heat Transfer
In Van Nuys ranch homes with attached garages, the shared wall is often uninsulated. In summer the garage becomes an oven. In the mild winter the garage leaks cold air through the door header. Foaming the garage wall and ceiling creates a thermal break. We do this job in a single trip with the same rig we use for the attic.
Trusted Brands We Service in Van Nuys
We install spray foam from Icynene and Demilec, the two brands we’ve found perform best on the high-heat, low-pitch attic decks common across Van Nuys. For homeowners who want a non-foam option, we also work with Owens Corning fiberglass and GreenFiber cellulose, and Rockwool for fire-resistant applications. Because we source from eight manufacturers total, you aren’t locked into whatever we happen to have on the truck. Van Nuys customers who need a specific product matched to their roof load get it. We keep spare tips, hoses, and enough material staged at our Corona shop to avoid a second trip for a Van Nuys install.
Common Spray Foam Insulation Problems We See in Van Nuys Homes
- Bare attic decks over 140-degree air. In the post-war ranch stock off Van Nuys Blvd, the original open-cell or nonexistent insulation leaves the ceiling framing exposed to intense heat. Closed-cell foam on the deck is the only material that cuts that radiant load effectively in this climate.
- Open-cell foam applied in the wrong place. Some crews will put open-cell on a hot-side attic deck, then wonder why the house still runs hot by late afternoon. In Van Nuys summer heat, closed-cell is the correct call for the roof deck and rim joists because it controls the vapor drive and radiant load open-cell cannot handle.
- Sealing the attic but leaving 1950s ducts unsealed. We find original metal ducts running through the hottest part of the attic in Van Nuys ranch and apartment stock. Foaming the deck while leaving those ducts leaky means conditioned air escapes into a space that’s still cooking at 140 degrees. We seal duct penetrations as part of every attic foam job.
- Big roll-up door headers acting as chimneys. On detached workshops and garages with oversized doors, the header and gable penetrations pull hot outside air straight into the conditioned space. Foam around those openings stops the chimney effect the same day it’s applied.
Pricing for Spray Foam Insulation in Van Nuys, CA
Here’s what Van Nuys homeowners can expect to spend on spray foam in this market. Open-cell attic floor foam runs $2,900 to $5,600 for a typical 1,200-square-foot ranch. Closed-cell attic deck foam on the same footprint runs $4,800 to $9,200, because the material is denser and the hot-side application takes longer. Crawl space work runs $2,200 to $4,800. Garage ceiling and wall foam runs $1,400 to $3,600. Rim joist sealing alone runs $900 to $2,100. The biggest cost drivers in Van Nuys are access, existing insulation removal, and whether we’re foaming the deck or the floor.

FAQs About Spray Foam Insulation in Van Nuys
Because Van Nuys ranch attics typically have none or next to no thermal barrier, and batts on a hot-side deck in the Valley summer don’t stop the radiant load the same way closed-cell spray foam does. Foam air-seals the gaps batts leave behind, and on a 1950s house with original framing, that air-sealing is most of the comfort win. The $1,200 to $2,400 you save on fiberglass will be lost in the first two summers of AC strain. Call us at (855) 382-3925 and we’ll inspect your attic for free.
Yes, and that’s exactly how we schedule it for Van Nuys customers. We pre-stage the rig, spare tips, hoses, and enough Icynene or Demilec material at our Corona yard so the crew doesn’t have to leave mid-job. A typical workshop ceiling and rim job finishes same day. The work is done in one trip, including the cleanup.
Yes, and it’s one of the biggest bang-for-the-buck spots in Van Nuys. The oversized roll-up door itself is always going to radiate heat from the afternoon sun, but foam on the ceiling and the wall between garage and house stops that heat from pushing into your living space. The header around the door gets sealed tight as part of the ceiling job. For a detached garage used as a workshop, the same ceiling foam lets a mini-split actually hold temperature instead of running continuously.
Yes, we always seal duct penetrations as part of any attic foam job in Van Nuys. The original metal ducts in 1950s and ’60s ranch homes leak, and when they’re sitting in attic air above 140 degrees, every leak pulls hot air into the conditioned space. We foam the deck, seal the rim, and tape and seal every duct penetration we can reach. That combination is what finally evens out the temperature in the rooms below. Call (855) 382-3925 for an inspection of your ductwork and attic.
Yes, most Van Nuys ranch homes built before 1970 have vented, shallow crawl spaces that leak cold air into the house all winter and pull moist earth air up all summer. Closed-cell foam on the subfloor and rim joists seals that space and keeps the floor temperature stable. We price crawl space work from $2,200 to $4,800 depending on access and square footage, and it can be included in the same trip as your attic. Give us a call for a free crawl space assessment.
