Fast, Reliable Spray Foam Insulation Across North Hollywood
Spray foam insulation in North Hollywood typically costs $1.50 to $3.80 per board foot for open-cell and $2.50 to $6.00 per board foot for closed-cell, with most garage ceiling or attic lid projects landing between $1,800 and $6,500 depending on square footage and prep work. We run crews into the 91601, 91605, 91606, 91615, and 91616 zip codes every week, and most estimates are free. If your upstairs rooms bake in the San Fernando Valley summer, the fix usually starts in the attic, not at the thermostat. Call (855) 362-0195 and Nelson Quirarte or one of our techs will walk you through what your house actually needs.
Why Even Air Insulation Is North Hollywood’s Preferred Spray Foam Insulation Company
We work in North Hollywood constantly, which means we know what the Valley heat does to a roof deck before we even climb the ladder. The North Hollywood housing stock runs from 1920s bungalows near the Arts District to newer tract homes off Vineland and Lankershim, and each one fails differently. A 1940s attic with collapsed paper-faced batts needs a different approach than a 2015 build with code-minimum fiberglass that never quite sealed the top plates.
Homeowners here tend to research insulation by brand before they ever call. That’s fine by us. We carry Icynene and Demilec spray foam, plus GreenFiber cellulose and Owens Corning fiberglass for spaces where foam doesn’t make sense. Nelson Quirarte built Even Air around the idea that the material should match the application, not the inventory. In North Hollywood, that usually means open-cell foam on the attic lid and garage ceiling, air-sealing on the top plates, and a hard look at whether the existing venting is actually moving hot air out.
We respond to North Hollywood calls same week in most cases, and emergency attic failures same day when the schedule allows. Homeowners tell us the estimate process is the part they appreciate most: we show up, take measurements, check what’s already up there, and tell you honestly whether spray foam is worth it in your specific house.
Open Cell Spray Foam in North Hollywood
Open Cell Spray Foam is the material we recommend most often in North Hollywood attics and garage ceilings, because it air-seals while it insulates and it’s forgiving on older framing. In a newer tract home where builder-grade batts have sagged off the garage ceiling joists, open-cell locks the assembly down and stops the stack effect that pulls broiling attic air into the living space above. In a 1940s bungalow, it fills the odd-shaped cavities and rim-joist gaps that fiberglass never quite reached.
Typical open-cell spray foam projects in North Hollywood run $1.50 to $3.80 per board foot, and a standard garage ceiling plus attic lid in a 1,200 to 1,800 square foot home usually lands between $2,800 and $5,500 once prep and air-sealing are included. It’s not the cheapest material per square foot, but it’s the one that actually stops the air movement that drives Valley heat gain.
Garage Ceiling Applications
Garage ceilings in North Hollywood tract homes are a recurring failure point. The builder put paper-faced batts up there because code said something had to go in, and within a few summers of 100°F attic heat, those batts sag, pull away from the joists, and leave an unsealed gap. Spray foam replaces that assembly rather than covering it. We’ve done enough of these off the NoHo Arts District corridor to know exactly what the failure looks like before we open the access hatch.
Attic Lid and Rim Joist Work
In homes built in the last 15 years, the attic lid is usually the one envelope assembly that’s still at code minimum. Recessed cans and wiring penetrations leak air past the fiberglass, and the top plates were never sealed. Open-cell foam sprayed across the lid after those penetrations are addressed turns a leaky, underperforming attic into a sealed assembly. The difference shows up within the first hot week.
Spray Foam Insulation Contractors in North Hollywood
Spray Foam Insulation Contractors in North Hollywood aren’t all the same, and we say that as a company that competes with them. Most contractors stock one foam system and push it on every job. We stock two, Icynene and Demilec, and we’ll tell you when foam isn’t the right call at all. That’s the difference between a contractor who installs one product and a specialist who matches the material to the house.
When you call us for spray foam in the 91605 or 91606 tract home neighborhoods, the first thing we do is check the attic ventilation. Foam sprayed too thin in a shallow, poorly vented attic can trap heat and moisture instead of resisting it. That’s a real failure we’ve corrected in homes where a previous contractor sprayed and ran. Thickness matters, venting matters, and prep matters.
Air-Sealing Before Foam
Foam without air-sealing is half a job. In newer master-planned homes around North Hollywood, we routinely find recessed cans, top-plate gaps, and wiring penetrations in the garage ceiling that leak air straight past the insulation. Our techs seal every penetration with can foam or caulk before the spray gun ever comes out. Skip that step and you’ve paid for foam that air moves around.
Correct Thickness and Venting
Open-cell foam in a Valley attic needs to be thick enough to do its job, usually 5.5 to 6 inches minimum on the lid for R-20 to R-21, and the venting above it has to actually work. In a low-pitch 1940s roof near the Arts District, that sometimes means adding baffles or upgrading the existing vents before we spray. We check both on every estimate. If the venting can’t be fixed, we’ll tell you and recommend a different material rather than spraying foam that’s going to hold heat.
Trusted Brands We Service in North Hollywood
North Hollywood homeowners tend to know their brands before they call, and we’re set up for that. We spray both Icynene and Demilec foam, which gives us access to open-cell and closed-cell formulations for different moisture and structural requirements. Where foam isn’t the right answer, we carry GreenFiber cellulose for dense-pack retrofits in older bungalow walls and Owens Corning fiberglass for attic blow-in work. We keep the material we need for North Hollywood jobs on the truck or a day out, so we’re not waiting on a supply house run when your attic is already 140°F. The right insulation for the job, not just the one we happen to stock.
Common Spray Foam Insulation Problems We See in North Hollywood Homes
- Builder-grade batts sagging off garage ceiling joists. Within a few summers of Valley heat, paper-faced fiberglass pulls away from the joists and leaves an unsealed air gap. Foam has to replace that assembly, not just cover it.
- Foam sprayed too thin in shallow, poorly vented attics. In the 91605 and 91606 tract homes especially, a previous contractor’s thin open-cell job can trap heat and moisture. Thickness and venting have to be checked before and after spraying.
- Unsealed recessed cans and top plates in newer builds. The 2010s-era infill homes near the NoHo Arts District have plenty of ceiling penetrations that leak air past the foam. If the boxes and plates aren’t sealed before spraying, the foam underperforms.
- Old attic fans and venting that dumps hot air instead of exhausting it. We find this constantly in 1940s bungalows near the Arts District, where an ancient attic fan or a misrouted vent is actively working against the insulation. The foam can’t fix a venting failure on its own.
Pricing for Spray Foam Insulation in North Hollywood, CA
Open-cell spray foam in North Hollywood runs $1.50 to $3.80 per board foot, and closed-cell runs $2.50 to $6.00 per board foot. A typical garage ceiling plus attic lid in a 1,200 to 1,800 square foot home lands between $2,800 and $5,500 for open-cell, including air-sealing and prep. Closed-cell jobs on roof decks or rim joists usually run higher, from $6,000 to $12,000, because the material costs roughly double and the application is more demanding. What moves the price most is square footage, access difficulty, how much air-sealing the existing attic needs, and whether old insulation has to come out first. Call (855) 362-0195 for a free estimate, and we’ll give you a real number for your specific roof, not a range that covers every house in the Valley.

FAQs About Spray Foam Insulation in North Hollywood
Because builders insulate to code minimum, and code minimum in the San Fernando Valley isn’t enough for 100°F+ attic heat that runs from June through September. The thickest builder batt can’t air-seal top plates, recessed cans, or wiring penetrations, and air moving through those gaps is what cooks your upstairs rooms. Spray foam seals and insulates in one step. Call (855) 362-0195 and we’ll tell you if your newer build actually needs it or if air-sealing alone would do the job.
Usually yes, but the prep work matters more than the foam. Those low-pitch roofs and shallow attics often have ancient attic fans, collapsed batts, and venting that doesn’t move air. We fix the venting, seal the penetrations, and then spray open-cell foam across the lid and rim joists. Done right, it transforms a bungalow that could never hold temperature. Done wrong, the foam just traps the same heat it was supposed to resist.
Open-cell Icynene is our default for garage ceilings in North Hollywood tract homes. It air-seals while it insulates, it’s forgiving on the framing, and it locks the ceiling assembly down so the batts can’t sag off the joists again. If the garage has a finished living space above it or moisture concerns, we’ll look at closed-cell Demilec instead. We stock both, so the call is made on your house’s specifics, not what’s on the truck.
Yes, if the attic lid is the problem, and in North Hollywood it usually is. The heat gain that cooks upstairs rooms comes through the attic, not the walls. Air-sealing the top plates and can lights, then spraying open-cell foam across the lid, stops the hot air from dumping into the living space. We were called to a newer tract home off the NoHo Arts District corridor where the upstairs rooms were hitting 85°F by mid-afternoon. After air-sealing and spraying the attic lid and garage ceiling, the upstairs stabilized and the AC stopped short-cycling. Call (855) 362-0195 and we’ll tell you whether your attic is doing the same thing.
Yes, and sooner than you think. Builder warranties on insulation and envelope work in North Hollywood typically run 1 to 10 years depending on the component, and once they lapse, you pay full freight. We inspect attics and garage ceilings during the warranty window and document what’s failed or underperforming, so you can take that back to the builder with specifics. If the builder won’t fix it, you’ll at least know exactly what needs doing before the next heat wave.
