Fast, Reliable Spray Foam Insulation Across North Hollywood
Spray foam insulation in North Hollywood runs $2,100 to $5,400 for a typical attic or crawl space job, and we’re usually on-site within 48 hours of your call. That price buys you an air seal no fiberglass batt can match: closed-cell foam stops the 100°F San Fernando Valley heat at the roofline, not inside your ceiling. Laurel Attic Insulation Los Angeles has crews working North Hollywood daily, from the 1940s bungalows off Vineland to the newer townhomes tucked behind Burbank Boulevard. Call (213) 698-7067 for a written price before anything starts.
If you’re in a pre-1970 North Hollywood home, you already know the drill: bedrooms that bake by 2 p.m., a heater that runs all winter, and energy bills that climb every July. The problem isn’t your AC. It’s the uninsulated wall cavities, the thin attic layer, and the gaps around every penetration. Our Spray Foam Insulation team seals those openings with foam that expands to fill the cavity completely, then hardens into an air barrier. That’s the fix, and it’s one we’ve applied in hundreds of North Hollywood attics, crawl spaces, and garages.
Why Laurel Attic Insulation Los Angeles Is North Hollywood’s Preferred Spray Foam Insulation Company
North Hollywood homeowners tell us the same thing: they called two other insulation companies, one quoted a vague number over the phone, the other never showed. We built Laurel around the opposite approach. You book a time, you get a live arrival window you can track from your phone, and a written price lands in your hand before we unload a single hose. No door-step changes. No “actually, that’s an upcharge.” That’s the Relay Visibility Guarantee, and it’s on every job we do in North Hollywood.
Our North Hollywood reviews consistently mention three things: the crew showed up when they said they would, the price didn’t move, and the job came with before-and-after photos proving what was done. We also carry the 365-Day Done Right Promise on every spray foam installation. If something isn’t right within a full year, we make it right in writing. No argument, no charge.
We’re coordinated from the Laurel Attic Insulation Los Angeles office, with dispatch and scheduling handled there, and local crews serving North Hollywood directly. That means when you call at 9 p.m. because your attic is still 95°F and you want someone out tomorrow, a live person answers. 24/7, no callback queue, no voicemail tag.
Crawl Space Spray Foam Insulation in North Hollywood
Crawl Space Spray Foam Insulation in North Hollywood usually means post-1960 homes with raised foundations, where the floor over the crawl space turns into a cold slab every winter night. We typically see open dirt floors and fiberglass batts that have sagged, absorbed moisture, and stopped working years ago. The fix is closed-cell foam sprayed directly onto the crawl space walls and the rim joist band. That seals out soil moisture, stops cold air from rising through your floors, and keeps rodents from chewing through the old batt.
Soil Moisture and Open-Cavity Sealing
North Hollywood’s clay-heavy soil holds water after winter rains, which means crawl space humidity spikes fast. A floor insulated with damp fiberglass loses R-value and can hold moisture against your subfloor. Closed-cell spray foam doesn’t absorb water. We apply it from the foundation sill down to a few inches above grade, creating a continuous moisture and air barrier that fiberglass can’t replicate.
When a North Hollywood Homeowner Needs It
If your kitchen floor feels like ice in January, or you’re running a space heater just to keep the living room tolerable, your crawl space is part of the problem. We also flag this on homes where termite damage has compromised older insulation. Spray foam won’t hide termite activity, so we always recommend a clear inspection before we seal the space. A typical crawl space spray foam job in North Hollywood runs $1,200 to $3,800 depending on square footage and access height.
Garage Spray Foam Insulation in North Hollywood
Garage Spray Foam Insulation in North Hollywood is one of the fastest-returning improvements you can make, especially if you’ve converted the garage into a home office, gym, or ADU. Many North Hollywood garages are exposed to the west sun with uninsulated roofs, and on a July afternoon the interior can hit 120°F. We spray closed-cell foam directly onto the garage ceiling and the wall against the house, which drops the temperature more than you’d expect and cuts the sound transfer into your living space.
ADU and Title 24 Fire-Safing
If your North Hollywood garage is a permitted ADU or Jr. ADU, California’s Title 24 energy code applies, and that means specific fire-safing and R-value minimums. Closed-cell spray foam meets those standards when applied to the roof deck and walls. We handle the fire-blocking details the inspectors look for, because we’ve done it on dozens of Valley ADUs.
Alley Access and Tight Clearances
A lot of North Hollywood garages open onto alleys barely one car wide. Foam trucks don’t fit, so we run hoses from the street and work with portable equipment. We shroud our nozzles near parked cars. Overspray drifting onto a neighbor’s sedan is the kind of mistake that gives insulation contractors a bad name, and we avoid it by design. Garage spray foam in North Hollywood typically costs $1,600 to $4,200, with most jobs landing around $2,800.
Trusted Brands We Service in North Hollywood
We stock materials from Owens Corning, Rockwool, and Demilec, and we match the foam to the job rather than whatever is riding on the truck. Closed-cell jobs in North Hollywood’s pre-1970 wall cavities need a specific low-exotherm formula so the curing heat doesn’t crack the original plaster. Rim joist work in 1980s apartment buildings gets a different open-cell product for sound control. We keep local parts and material inventory staged for North Hollywood stops, so when a crew finishes a Burbank Boulevard job and you’re next on the route, we’re not waiting on a supply run.
Common Spray Foam Insulation Problems We See in North Hollywood Homes
- Overspray on alley-parked cars. North Hollywood’s townhome alleys are tight, and unshrouded nozzles can drift foam onto vehicles below attic vents. We shroud every nozzle and tape off vents before spraying near any parked car or walkway.
- Closed-cell foam over knob-and-tube wiring. Pre-1960 North Hollywood homes often still have active knob-and-tube. Applying high-exotherm closed-cell foam directly over it with no air gap traps heat and can accelerate wire insulation breakdown. We assess wiring first and use a low-exotherm or open-cell product where needed.
- Cracked plaster from one-size-fits-all foam. Uninsulated wall cavities in 1940s bungalows need injection foam with carefully controlled expansion pressure. A generic formula can bow or crack the interior plaster. We use low-pressure injection on these homes specifically.
- Fiberglass batts degrading under Valley sun. North Hollywood’s strong sun and temperature swings bake older batts until they settle and lose much of their R-value. We see this in nearly every tear-out we do, and spray foam’s air-sealing properties mean it won’t settle the same way.

Most North Hollywood spray foam jobs fall between $1,200 and $5,400. A small rim joist or crawl space band seal starts around $1,200 to $2,000.

FAQs About Spray Foam Insulation in North Hollywood
Yes. We run hoses through scuttles as small as 18 inches square, which is exactly what we did on a 1950s ranch near Vineland and Burbank where the original ‘California ceiling’ access was barely wider than a pizza box. The foam expands inside the attic cavity, so we don’t need to fit equipment through the opening. Call (213) 698-7067 and we’ll tell you if your scuttle will work for the product we recommend.
Open-cell spray foam reduces sound transfer between units by sealing the air gaps that carry noise, though it won’t replace a dedicated acoustic assembly. In 1980s North Hollywood apartment buildings with shared walls, we typically spray open-cell into the rim joist and wall cavities where sound bleeds through. Pair it with mass-loaded vinyl or resilient channels for the best result. We can quote the soundproofing portion separately so you know exactly what you’re paying for.
Closed-cell foam applied directly over live knob-and-tube can trap heat and accelerate wire insulation breakdown, which is a genuine fire risk. On pre-1960 North Hollywood homes, we inspect the wiring first and either use a low-exotherm formula, add an air gap, or recommend an electrician verify the circuit before we spray. We won’t seal over active knob-and-tube without addressing it. Get a free assessment by calling (213) 698-7067.
Closed-cell spray foam does not settle, sag, or lose R-value from UV exposure the way fiberglass batts do, because it’s installed inside the attic cavity, not on the exposed roof deck. North Hollywood’s summer highs above 100°F degrade older batts through thermal cycling, but spray foam’s structure stays intact for decades. We’ve gone back into attics we sprayed ten years ago and the foam looks the same as the day we applied it.
Yes. We park the truck on the street and run hoses the last 40 to 80 feet to your garage, which is standard for North Hollywood’s tight alley-access lots. We shroud every nozzle to prevent overspray onto cars or walls, and we tape off vents before we start. It adds a little time, but it doesn’t change your written price. Call (213) 698-7067 for an exact quote, or to schedule us to take a look.
