Spray Foam Insulation in Van Nuys — Same-Day Service, Done Right the First Time

Fast, Reliable Spray Foam Insulation Across Van Nuys

Spray foam insulation in Van Nuys typically costs $3.50 – $7.00 per board foot for open-cell and $5.50 – $9.50 for closed-cell, with a full attic retrofit on a 1,200 sq ft home running $6,800 – $9,400. Most jobs in Van Nuys take one to two days once we start. That’s the honest math. If your mid-century home still has the original fiberglass batts, you’re losing conditioned air through the attic floor every single day, and July in the 91405 ZIP code doesn’t forgive that.

Why Even Air Insulation Is Van Nuys’s Preferred Spray Foam Insulation Company

We’re not a franchise with a rotating door of techs. Even Air Insulation is led by Nelson Quirarte, and the crew that works Van Nuys knows what’s behind those stucco walls and low-pitch roofs that dominate the neighborhood’s post-WWII tracts. When we walk into a 1956 ranch off Kester Avenue, we expect to find 2×4 framing, maybe 4 inches of disintegrated fiberglass, and the occasional knob-and-tube surprise. That’s not a problem for us. It’s the job.

Van Nuys homeowners call us because we carry Spray Foam Insulation capability with both Icynene and Demilec product lines, which means we can match the foam to your ceiling assembly rather than forcing one product into every attic. Response time to Van Nuys is typically same-week scheduling for estimates and under two weeks for installs, depending on scope. We’re centrally located in Koreatown, so we can reach Van Nuys off the 405 or the 170 without burning half the day in traffic.

Open Cell Spray Foam in Van Nuys

Open Cell Spray Foam is the workhorse for Van Nuys attic retrofits because it expands to roughly 100 times its liquid volume and fills the irregular cavities in older framing. In a 1950s Van Nuys tract home with a low-pitched roof and barely a foot of clearance at the eaves, we can apply open-cell foam to the underside of the roof deck and bring the assembly to R-30 without needing a vapor barrier. This matters in our climate, where the attic hits 150°F in August and winter nights dip into the 30s. Open-cell handles both directions.

Pricing for open-cell spray foam in Van Nuys runs $3.50 – $4.75 per board foot depending on depth and access. A typical 1,000 sq ft attic floor application lands between $5,000 and $7,200. The foam cures within a day, and you’ll notice the upstairs bedrooms hold temperature by the next afternoon.

Roof Deck and Rim Joist Work

On Van Nuys homes where the attic is used for storage or houses an older HVAC unit, we shift to roof-deck application. Sealing the tectonic joints and penetrations first, then applying 6 – 9 inches of open-cell under the sheathing, makes the attic itself conditioned space. Rim joist foam in raised-foundation homes along the 91405 and 91411 blocks stops the cold-air intrusion that makes floors ice-cold in January.

When Open-Cell Makes Sense

If you hear street noise from Van Nuys Boulevard or Sepulveda, open-cell’s density dampens sound transfer better than closed-cell. For older homes with existing roof leaks or moisture history, open-cell’s vapor permeance lets the deck dry toward the interior. Nelson Quirarte’s crews have used this approach on dozens of Van Nuys homes with original tongue-and-groove decking that would trap moisture under closed-cell.

Spray Foam Insulation Contractors in Van Nuys

Spray Foam Insulation Contractors are not all the same, and in Van Nuys the difference shows up fast. Contractors who don’t work this neighborhood regularly won’t know that many local attics still have knob-and-tube wiring, or that the original fiberglass batts are often caked with 60 years of rodent activity and dust. Spraying over either one is a fire hazard or an adhesion failure. We know, because we’ve fixed both.

Hiring the right contractor in Van Nuys means asking whether they’ll inspect your wiring before quoting, whether they pull the old batts before spraying, and whether they ventilate properly on low-pitch roofs. We do all three. A full attic retrofit with spray foam and prep work on a Van Nuys home typically runs $6,800 – $9,400 including removal of debris and sealing of penetrations.

Initial Assessment and Wiring Check

Before we touch a Van Nuys attic, we check the electrical. If the home still has active knob-and-tube circuits, spray foam can’t go over them. Spray foam cures around the wire and traps heat, which breaks down the insulation and can arc. We coordinate with a licensed electrician to update or isolate those runs first.

Garage Ceiling and Bonus Room Applications

Many Van Nuys homes have converted garages or added bonus rooms that were built with no insulation at all. Spraying the garage ceiling with closed-cell in a 1963 home near Van Nuys High School changes that space from unusable in summer to an actual workshop or guest room. Garage ceiling foam in Van Nuys generally runs $3,800 – $6,000 for a two-car garage.

Trusted Brands We Service in Van Nuys

We don’t push one manufacturer because it’s what we stock. For Van Nuys attics we commonly spec Icynene open-cell for roof-deck and attic-floor applications where breathability matters, and Demilec closed-cell for rim joists, garage ceilings, and any area where we need water resistance or a higher R-value per inch. Both brands hold up under the extreme attic heat that Van Nuys sees from June through September. For homes where sprayed foam isn’t the right call at all, we’re equally comfortable with GreenFiber blown-in cellulose and Owens Corning batts. The right insulation for the job, not just the one we happen to stock.

Common Spray Foam Insulation Problems We See in Van Nuys Homes

• Compressed, contaminated original batts. Homes built along Van Nuys Boulevard and Valerio Street in the 1950s often have fiberglass batts compressed to an inch of useless matting, riddled with rodent tunnels and dust. We remove these before spraying; leaving them under foam causes odor and adhesion failure.
• Knob-and-tube wiring discovered mid-job. It’s common enough in the 91401 and 91405 blocks that we always inspect first. Foam over live knob-and-tube is a code violation and a fire risk.
• Low-pitch roofs with minimal clearance. Many Van Nuys homes have roofs with less than 18 inches of rise. Closed-cell foam without proper ventilation traps off-gassing and moisture, which leads to deck rot. We use low-rise rigs and adjust ventilation for these jobs.
• Rodent-damaged decking and soffits. Rats and squirrels in the Valley’s older attics chew through baffles and leave openings at the eaves. We seal entry points and replace damaged vents before any foam goes in, or the new insulation just becomes another nesting site.
