Insulation Company in Florence-Graham, CA
Most homes in Florence-Graham were built between the 1940s and 1960s with little or no insulation in the attic and none in the walls. That means cooling costs spike every summer as radiant heat pours through uninsulated stucco and baked roof framing. Hollywood Insulation Co specializes in blown in insulation for exactly this housing stock, and we’ve served Florence-Graham since 2018. Call (866) 605-6949 for a free estimate on retrofit insulation that actually fits a 90001 home.
Why Florence-Graham Homes Are Different
Florence-Graham is a densely packed, unincorporated pocket of South LA where small mid-century stucco bungalows and low-rise multi-units sit shoulder-to-shoulder on narrow lots. The housing stock here is almost entirely 1940s to 1960s wood-frame construction behind stucco, and most of those attics were built with a skim of fiberglass or nothing at all. Walls are typically uninsulated wood framing, which means heat moves straight through the stucco into living space from June through October.
The climate drives the work more than anything else. Florence-Graham gets long, hot, dry summers with mild winters, so cooling loads dominate. The real comfort problem isn’t the furnace; it’s attic radiant-heat gain. A 1960s bungalow on a 90-degree August afternoon can have an attic that’s 130 degrees or hotter. That heat radiates down through the ceiling all evening, and the AC never catches up. Air sealing plus dense-pack cellulose or blown in fiberglass changes that equation immediately.
Narrow lots create access problems you won’t see in newer subdivisions. Houses here are built nearly lot-line to lot-line, which leaves little roof or side clearance. Our crews regularly work off tight eaves, through small closet hatches, or from ladders set in alleys. We plan every Florence-Graham job around that reality, bringing the right hose lengths, ladder setups, and cleanup gear for tight access.
Our Main Florence-Graham Services
Two services account for most of the insulation work we do in Florence-Graham: attic insulation retrofits and spray foam air sealing. Here’s what each involves locally.
Attic Insulation in Florence-Graham
Attic work in Florence-Graham usually means pulling out old, compressed fiberglass and blowing in fresh coverage to code depth, then air sealing every penetration before we finish. The goal is a cooler ceiling in August and a measurably lower cooling bill. Because most attics here are small and tight, we send crews who know how to work fast and clean around renters’ belongings and narrow hatch access. See the full breakdown: Attic Insulation in Florence-Graham.

Spray Foam Insulation in Florence-Graham
Spray foam fills a specific gap in Florence-Graham: the uninsulated wall cavities and open attic transitions that blow-in alone can’t reach. Closed-cell foam like Demilec or Icynene open-cell foam air seals and insulates in one pass, which matters on stucco homes where the wall cavity is the only barrier between you and 95-degree siding. We apply foam where it earns its cost, not as a default. Details here: Spray Foam Insulation in Florence-Graham.

Blown In Insulation in Florence-Graham
Blown in insulation is the workhorse retrofit for Florence-Graham’s 1940s to 1960s stucco homes because it’s the only practical way to add meaningful R-value to existing attics and uninsulated wall cavities without tearing open walls or rebuilding the roof. Long hot summers mean the payoff is a cooler home and a lower cooling bill within the first season. It’s also fast enough to finish in a morning, which matters when you’re working around renters and tight lot access in 90001. Our team installs blown in insulation as a core method, alongside Blown In Insulation resources we maintain for every job type.

Which insulation is better for a Florence-Graham attic, cellulose or fiberglass?
Cellulose, our GreenFiber option, packs tighter and slows airflow better in old attic cavities. Fiberglass is lighter and slightly cheaper. For 1940s – 60s Florence-Graham attics with irregular framing, cellulose usually performs better. Call for a recommendation based on your specific attic.

Most Florence-Graham attic jobs finish in 4 to 6 hours including cleanup. Dense-pack wall work can take a full day. Tight access on narrow lots sometimes adds an hour or two, but we schedule accordingly.

What Florence-Graham Customers Say
"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Miguel Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Cole Sullivan
