Fast, Reliable Spray Foam Insulation Across Hollywood
Spray foam insulation in Hollywood typically costs $2.50 to $6.50 per square foot installed, and most attic jobs in the 90028 ZIP run between $4,800 and $14,000 depending on whether you go open-cell or closed-cell. We work in Hollywood every week, so we know the bungalows, the hillside lots, and the parking realities that come with jobs near Franklin Avenue or Sunset Boulevard. If your energy bills have crept up and certain rooms never hold temperature, call Orange County Insulation at (877) 680-3557 and we’ll walk you through what’s actually happening in your attic.
Why Orange County Insulation Is Hollywood’s Preferred Spray Foam Insulation Company
We only do insulation. Not roofs, not HVAC, not remodeling. That single focus means every crew member who shows up at a Hollywood job knows exactly what spray foam should look like against 100-year-old roof decking, and what it shouldn’t. Homeowners along Beachwood Canyon and the flats near Melrose keep calling us back because we don’t sell one material. We carry open-cell spray foam from Icynene and closed-cell from Demilec, plus fiberglass, mineral wool, and cellulose from the other brands on our roster. The right product for a 1928 bungalow with no insulation is not the same as the right product for a 1972 apartment building with thin ceiling cavities.
Noel Carrasco, our owner, built the company on this exact premise. When you call, you’re talking to a team that can explain why closed-cell makes sense on a roof deck but open-cell is often the better fit for an interior wall cavity. We bring that depth to every Hollywood estimate. And because Hollywood parking and permit windows are tight, we plan around them rather than treating them as an afterthought.
Spray Foam Insulation Contractors in Hollywood
Spray foam insulation contractors in Hollywood do a different job than their counterparts in newer parts of Los Angeles. Here, the work starts with what’s already in the cavity, and in pre-1940 housing that often means old debris, failed retrofit materials, and wiring nobody wants to touch. Our crews handle remediation before foam ever leaves the rig. It’s slower work, and it’s the only way to get adhesion that lasts.
Key Takeaways for Hollywood Spray Foam
Remediation Before Application
We pull old newspaper, rodent nesting, and failed insulation out first. Then we seal. Only after the cavity is clean and dry do we spray. Skipping this step is how Hollywood attics end up with foam that delaminates within a season.
Closed-Cell for Roof Decks
Closed-cell from Demilec is what we recommend for most Hollywood roof decks. A typical 1,200-square-foot attic roof deck in Hollywood runs $5,400 to $7,800 for two inches. It adds structural rigidity and blocks the radiant heat that turns attics here into ovens by 2 p.m. in August.
Spray Foam Attic Insulation in Hollywood
Spray foam attic insulation in Hollywood is the single most effective upgrade for older homes where the attic was never designed to hold insulation at all. We see bungalows near Hollywood Boulevard with attics filled with nothing but 80 years of dust, old copies of the Los Angeles Times, and the occasional squirrel nest. The foam doesn’t just insulate, it seals the gaps those pests used to get in.
A full attic spray foam job in the 90028 area runs $4,800 to $9,500 for open-cell and $6,000 to $14,000 for closed-cell, depending on square footage and access. Tight attics with low clearances and original trim add labor, but the result is the same: a home that finally holds temperature. If you’re working with an older Spanish Colonial Revival where the attic access is a small hatch in a closet ceiling, expect the job to take a little longer and cost a bit more on the labor side.
Air Sealing the Roof Deck
The real win in Hollywood attics is air sealing. Foam applied to the underside of the roof deck turns the attic into conditioned space, which matters on homes where the HVAC ducts run through the attic. In Hollywood, that’s most of them.
Noise Reduction
We frequently install spray foam in homes near Sunset, Hollywood, and Santa Monica Boulevards specifically because the homeowner can’t sleep through the nightlife. Closed-cell foam knocks down exterior noise meaningfully. One customer near the Boulevard told us the difference was like closing a window that had been stuck open for a decade.
Trusted Brands We Service in Hollywood
We stock and install spray foam from two specialist manufacturers, Icynene for open-cell and Demilec for closed-cell, and those sit alongside fiberglass, mineral wool, and cellulose options from brands like CertainTeed and GreenFiber. That breadth matters in Hollywood because no two attics here are the same. A 1965 apartment building with thin wall cavities needs a different material approach than a 1931 bungalow with a full attic. Since we’re not tied to one supplier, we recommend what actually fits the building and the budget. Our Spray Foam Insulation specialists keep local Hollywood job records, so repeat visits are faster and we already know the access quirks of your building.

FAQs About Spray Foam Insulation in Hollywood
No, we can’t. Spray foam needs a clean, dry surface to adhere properly. We remove the old newspaper, nesting material, and any failed insulation first, then clean and seal the decking before applying foam. In Hollywood’s pre-1940 bungalows, this remediation step is standard, not optional. Skipping it leads to delamination and wasted money. Call (877) 680-3557 and we’ll scope the attic before quoting anything.
Yes, but the wiring has to be isolated and sealed first. Knob-and-tube is live heat and foam traps heat. We don’t spray over it. We work around it, leaving proper clearance, and air seal the surrounding gaps. This is standard practice on Hollywood’s older homes and it passes inspection when done right.

Yes, meaningfully. Closed-cell spray foam is the most effective insulation we install for exterior noise reduction. It seals the gaps noise travels through and adds density to the building envelope. We have Hollywood customers near the boulevard who tell us the foam cut club and traffic noise more than any window upgrade they’d tried. The density of closed-cell is what does the work.
Closed-cell spray foam on the roof deck blocks radiant heat and seals the air leaks where wildfire smoke creeps in during fire season. Hollywood attics routinely exceed 130°F in summer without insulation. Closed-cell brings that way down, and because it air seals, it also reduces the smoke and particulate pull-through on bad air days.
Yes. Plaster is stable and holds foam well when applied correctly. We do not spray directly against damaged or crumbling plaster without surface preparation. On historic Hollywood homes, we’re careful around original lath and any trim, and we plan the application so the foam adds insulation without disturbing the plaster’s integrity.
If you’re in Hollywood and tired of rooms that won’t hold temperature, an attic full of decades-old debris, or noise from the boulevard that never lets up, call Orange County Insulation at (877) 680-3557. We’ll walk your attic, tell you what’s going on, and give you a straight number to fix it. Estimates are free, and we only do insulation. Which means we do it right.

What Hollywood Customers Say
Trusted by homeowners across Hollywood and surrounding areas.
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
