Insulation Company in Cudahy, CA
Blown in insulation is the workhorse retrofit for Cudahy’s tight, pre-1960s bungalows, where original attics often hold nothing but decades of dust and a single layer of fiberglass batts. Hollywood Insulation Co has served Cudahy since 2018, specializing in filling those low-clearance attic spaces and stubborn wall cavities that make summer heat feel inescapable. We’re a dedicated insulation contractor carrying eight manufacturer brands, so the material we recommend is the one that actually fits your home’s construction, not whatever happens to be on the truck that day.

Why Cudahy Homes Are Different
Cudahy is a dense, fully built-out 1.2-square-mile city in southeast LA County where nearly every home is a small pre-1960s California bungalow on a tight lot. That changes the insulation job from day one. We’re not sealing a new roof deck with full attic headroom. We’re working in attics that are often barely 3 to 4 feet high, with knob-and-tube wiring still active in some corners and no soffit vents to speak of.
The housing stock here is predominantly 1920s-to-1950s stucco bungalows with low-pitch roofs. Many walls have no insulation at all. Attics were framed to hold air, not comfort. In summer, inland South LA County gets long, hot, smoggy stretches with triple-digit heat spells, and that attic becomes an oven radiating heat down through the ceiling all night. Mild winters mean the cooling load dominates, so attic insulation and air sealing pay back faster here than heating-driven measures ever could. Add the constant overhead of LAX-bound flight paths, and a tighter attic also cuts down on aircraft noise inside the house.
This is retrofit work in occupied homes. We coordinate around your family’s schedule, respect the tight property lines that leave little staging room, and build our install plan around the realities of old framing rather than assuming a blank slate.
Our Main Cudahy Services
Cudahy homeowners and the contractors working on their remodels usually reach out about two jobs: bringing an old attic up to modern performance with attic insulation, and sealing stubborn air leaks and thermal bypasses with spray foam. Each gets its own detailed page.
Attic Insulation in Cudahy
In these old bungalows, the attic is the single biggest source of heat gain in summer and the easiest place to regain control of indoor temperatures. We work with blown-in fiberglass, cellulose, and mineral wool to build a continuous thermal barrier, even in spaces where rafters are only a few feet apart. Low-pitch roofs and tight clearances are the norm here, and our crews are used to maneuvering in them without compromising the install. If you’re not sure what’s currently up there, it’s worth having a professional look before another triple-digit summer arrives. Full details are on the Attic Insulation in Cudahy page.
Spray Foam Insulation in Cudahy
Spray foam does two jobs at once: it insulates and it air-seals. In a 1940s Cudahy bungalow with unsealed top plates and gaps around old electrical boxes, that second job can matter more than the R-value alone. We install both Icynene open-cell and Demilec closed-cell systems, choosing the right chemistry for the location. Closed-cell adds significant moisture resistance, which matters in an attic that sees radical temperature swings. Open-cell is often the right call for interior walls where sound control from those flight paths is a priority. See the Spray Foam Insulation in Cudahy page for specifics.

Blown In Insulation in Cudahy
Blown in insulation is the most practical retrofit for Cudahy’s older homes because it can be installed without tearing open walls or ceilings. In a 1,000-square-foot bungalow with original plaster and no existing wall insulation, blowing cellulose or fiberglass into the stud cavities from the exterior is often the only way to get insulation into those walls without a gut remodel. It’s also the fastest way to top up a thin attic floor to current recommended depths. This is the core of our dedicated Blown In Insulation work, and it’s the service most Cudahy homeowners call us about first.
Cellulose Insulation
Signs you need it
Rooms that won’t hold temperature, drafts near baseboards in winter, and attic insulation that’s settled to a fraction of its original depth.
What it costs in Cudahy
Cellulose insulation in Cudahy typically runs $1.10 to $1.80 per square foot installed, depending on depth and access.
How we do it
We drill small access holes in exterior walls or use the attic hatch, blown in GreenFiber recycled cellulose at the target density, then patch and texture the holes to match.
Blown In Attic Insulation
Signs you need it
Second-floor rooms that bake in summer, snow-like dust in the attic in winter, or visible ceiling joists where insulation should sit above them.
What it costs in Cudahy
Blown in attic insulation for a typical Cudahy bungalow attic falls between $1,200 and $2,600 for the full job.
How we do it
We air-seal the attic floor penetrations, install or verify ventilation where framing allows, then blow loose-fill insulation to the specified depth across the entire attic floor.
Blown In Cellulose Insulation
Signs you need it
You can feel the heat radiating through the ceiling on summer nights and the existing batts are compressed, torn, or missing in sections.
What it costs in Cudahy
Expect $1.10 to $1.80 per square foot installed for blown in cellulose in Cudahy, with attic jobs on the lower end of that range.
How we do it
We use a high-volume blower to distribute GreenFiber cellulose evenly, reaching threshold depths without compacting the material and compromising its R-value.
Loose Fill Insulation
Signs you need it
Fluctuating indoor temperatures, uneven heat between rooms, and attic spaces that are difficult to reach with batt insulation.
What it costs in Cudahy
Loose fill insulation in Cudahy ranges from $1.00 to $1.50 per square foot installed, varying with material and final depth.
How we do it
We blow loose fill material through a hose into the target cavity, letting it settle into irregular corners and around obstacles that batts can’t reach.

What Cudahy Customers Say
"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"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong"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
