Fast, Reliable Spray Foam Insulation Across Florence-Graham
Spray foam insulation in Florence-Graham typically runs $2.50 to $6.50 per board foot installed, with most whole-attic retrofits on the 1940s – 60s stucco bungalows here landing between $3,800 and $9,500.

Why Hollywood Insulation Co Is Florence-Graham’s Preferred Spray Foam Insulation Company
We’re not a general contractor who also does insulation. We’re an insulation specialist, and every member of our Spray Foam Insulation team lives in this one trade, diagnosing thermal bypasses, air leakage, and R-value deficiencies all day, every day. For Florence-Graham homeowners, that matters because the homes here are unforgiving: uninsulated wood-frame walls behind brittle 1950s stucco, attics with barely an inch of settled fiberglass, and narrow side yards that make every exterior access point a puzzle.
Our trucks roll into Florence-Graham regularly, and our crews know the rhythm of the neighborhood. We’ve worked around renters napping before night shifts, parked ladders in alleys off Gage and Compton, and kept tarps tight against the dust of an old plaster-over-gypsum demo. We carry systems from Icynene and Demilec specifically for closed-cavity injection and attic air-sealing projects here, because the open-cavity approach that works in new-build suburbs simply doesn’t apply to a 90001 bungalow. We also bring the full material portfolio: eight manufacturer brands spanning fiberglass, mineral wool, spray foam, and cellulose, so the recommendation you get is matched to your home, not to whatever happens to be on the truck.
Open Cell Spray Foam in Florence-Graham
Open cell spray foam in Florence-Graham is our default recommendation for attics, rim joists, and interior wall cavities where you need air sealing plus sound dampening more than maximum R-value per inch. For the small mid-century attics across 90001, open cell foam from Icynene expands into every gap around framing, electrical penetrations, and old furnace flue chases, stopping the radiant-heat gain that turns an uninsulated attic into an oven by 2 p.m. Expect $2.50 to $4.50 per board foot installed, with a typical 1,000-square-foot attic at the 5.5-inch depth running $3,200 to $5,800.
Dense-Pack Wall Injection Through Closets
Many Florence-Graham bungalows have empty wall cavities behind original stucco. We inject open cell foam through small holes drilled in interior closet drywall, then patch and texture to match. The foam fills the cavity without tearing off stucco, and the home stays cooler without a full exterior remodel.
Attic Air-Sealing Plus R-Value
In 90001, air leaks around recessed lights, plumbing vents, and the attic hatch can move more heat than the insulation itself stops. Open cell foam seals those bypasses while insulating in one pass, which is why we pair it with attic ventilation and any existing blown-in material rather than forcing a full removal.
Closed Cell Spray Foam in Florence-Graham
Closed cell spray foam in Florence-Graham runs $4.50 to $6.50 per board foot installed and makes sense when you need higher R-value per inch, moisture resistance, or structural racking strength, typically on rim joists, undersides of roof decks, or in tight cavities where depth is limited. For older homes near Florence Avenue where crawl or attic access runs shallow, a two-inch lift of Demilec closed cell delivers about R-13.5 while also acting as an air and vapor barrier. It’s the right call when open cell would eat too much headroom, and it’s a common upgrade on the low-rise multi-family units creeping into the neighborhood’s housing stock.
Spray Foam Insulation Contractors in Florence-Graham
Spray foam insulation contractors in Florence-Graham need to know the difference between closed-cavity and open-cavity work. Our Florence-Graham crews have run injection jobs through closet drywall, worked off alley-side ladders within inches of the neighboring stucco wall, and dealt with the brittle substrate that cracks when a cavity is overfilled. For a 1950s stucco bungalow, the dense-pack or injection approach costs $4,000 to $9,000 for walls and attic combined, depending on access and square footage.
Retrofit Injections Without Stucco Removal
Most Florence-Graham homeowners want the insulation benefit without a full re-stucco. We drill from the interior, shoot foam into the cavity, and patch cleanly. The key is monitoring fill rate so the 70-year-old stucco doesn’t blow out from pressure.
Attic and Rim Joist Work on Tight Lots
Houses built lot-line to lot-line leave little room for staging. We work off ladders in side alleys or through the attic scuttle, and we schedule around tenant access when the property is a rental. Every job gets a pre-fill inspection of the wall cavities and attic bypasses first.
Spray Foam Roof Deck Insulation for Florence-Graham Homes
Spray foam roof deck insulation in Florence-Graham is a specialty for homes with unvented attics or converted attic spaces where the ceiling plane can’t be insulated from below. Applying Demilec or Icynene directly to the underside of the roof deck moves the building envelope to the roofline, which stops the radiant-heat bake that builds in the small, tight attics common across 90001. Typical cost runs $6,000 to $11,000 for a full attic roof deck, though smaller jobs like a single hot room under a low slope run less. The real benefit for Florence-Graham is eliminating the attic as a superheated buffer zone entirely.
Garage Ceiling Spray Foam in Florence-Graham
Garage ceiling spray foam in Florence-Graham addresses a specific problem: attached garages built into the original 1940s – 60s bungalows where the garage ceiling opens directly into the attic. Uninsulated garage ceilings bleed heat into the living space above or pull hot air into the laundry area shared by older duplexes. We typically spray open cell Icynene at a two to three-inch lift under the garage ceiling deck, running $1,200 to $2,800 for a standard one-car garage in 90001. It’s a fast job we can usually schedule within the same week, and it makes an immediate difference in the bedroom that sits over the garage.
Rim Joist Spray Foam for Florence-Graham Duplexes
Rim joist spray foam in Florence-Graham is one of the most cost-effective air-sealing upgrades we do on low-rise multi-family buildings and duplex conversions popping up off Compton and Florence Avenues. The rim joist, the band of wood around the perimeter of the floor framing, is a leak point nearly every 1940s and 1950s home here shares. We spray two inches of closed cell Demilec around the rim, stop the stack effect that pulls hot outdoor air in through the floor system, and keep pests out of the intersection between framing and foundation. Typical cost: $800 to $1,500 for a duplex perimeter, and it pays back through lower cooling bills in the first two summers.
Trusted Brands We Service in Florence-Graham
We install spray foam systems from Icynene and Demilec, and we keep the full material portfolio on hand for every Florence-Graham job: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and GreenFiber for the blown-in, batt, and mineral wool applications that sometimes pair with a foam retrofit. What that means for a 90001 homeowner is simple: the recommendation comes from what your home actually needs, not from whatever’s loaded on the truck that morning. For sustainability-minded customers, GreenFiber recycled cellulose and Rockwool mineral wool give high-performance alternatives without a special-order wait. Eight trusted brands, one honest recommendation. That’s the approach, and Noel Camacho built the company on it.
Common Spray Foam Insulation Problems We See in Florence-Graham Homes
- Foam applied over unsealed stucco cracks traps moisture inside the wall cavity. We’ve seen paint blister on the interior face of a 1950s bungalow because a previous contractor shot closed cell foam into a cavity without air-sealing the cracked stucco first. The result was trapped humidity and a callback that cost more than the original job. We inspect the exterior before any wall injection in Florence-Graham.
- Off-ratio two-part foam in tight attics never cures. When a two-part spray foam system is mixed at the wrong ratio in a small, hot 90001 attic, the foam stays sticky and must be cut out by hand. We see this on jobs where the installer lacked a heated proportioner or rushed the setup in a confined space.
- Overfilling wall cavities blows out brittle 1950s stucco. The stucco on Florence-Graham’s original bungalows is hard but brittle, and applying too much injection pressure creates cracks on the exterior. Our crews watch fill rate and pressure through the injection holes to keep the stucco intact.
- Narrow lots leave no roof access, so crews skip the eave sealing. Houses built nearly lot-line to lot-line often force access through alleys and over low eaves. Some installers skip the hard-to-reach attic bypasses, and the foam job underperforms. We work from ladders in the alley or through the attic scuttle to seal what actually drives the heat gain.

We schedule around tenant access, cover belongings with plastic, work in defined zones, and keep noise and dust contained to the area we’re actively spraying. Most attic and wall injection jobs on occupied rentals finish in one to two days, and tenants can stay in the unit during the work.
If you own a rental property in 90001, call us for a timeline and a quote that accounts for tenant scheduling.
Yes, attic spray foam stops the radiant-heat gain that turns an uninsulated Florence-Graham attic into a 140-degree oven, which is the main driver of hot bedrooms and overworked window ACs here. Sealing the attic bypasses plus adding open cell foam typically brings second-floor and back rooms to a noticeably more stable temperature.
Call (866) 605-6949 and we’ll tell you what your attic needs after a quick look.
Open cell Icynene is usually the right pick for narrow-lot Florence-Graham homes because it’s lighter, fills tight cavities well, and can be injected through interior access points when we can’t reach the exterior. For rim joists or shallow cavities, we use closed cell Demilec for higher R-value per inch.
We’ll assess your access points and recommend the system that fits your lot.
For most retrofit insulation work on existing 1940s – 60s bungalows and duplexes in 90001, no separate insulation permit is required, but if the job involves structural changes or re-roofing at the deck level, you may need one. We can confirm what applies to your specific project when we inspect the home.
