Insulation Company in West Hollywood, CA
Blown-in insulation is the workhorse answer for most West Hollywood homes, because the city’s attics and walls were mostly closed up decades before anyone thought about heat control. The typical West Hollywood house or apartment here went up between the 1920s and the 1950s, when lath-and-plaster walls and open stud bays were standard and attic insulation was an afterthought. That means the job is almost never new construction. It’s adding loose fill to a cavity that already exists, sealing the hot afternoon air that leaks in, and doing it without tearing a rental unit apart. Call (866) 942-5951 to schedule a free estimate.
Why West Hollywood Homes Are Different
West Hollywood sits in a mild, dry Mediterranean pocket, but that mildness hides a real problem: hot inland air pushes through in the afternoon, and coastal nights pull the temperature back down. The result is a swing that shows up in west- and south-facing rooms long before it shows up on a heating bill. Insulation here is less about keeping cold out and more about blocking radiant heat and air-sealing against the afternoon surge.
The housing stock makes it harder. Dense low-rise rental buildings from the 1920s through the 1960s mix with original Spanish Colonial and Craftsman bungalows, and many still carry lath-and-plaster walls, knob-and-tube wiring, and thin or missing attic insulation. In the tight rental blocks around 90069, the job often does double duty as sound control between units, since tenants complain about neighbor noise as much as heat. Fiberglass batts and blown-in fill get specified for sound transmission as much as for thermal value. Every penetration has to be patched and sound-isolated, not just filled.
Our Main West Hollywood Services
West Hollywood homeowners call us most about two things: bringing an old attic up to a usable thermal barrier, and sealing the gaps that make a room feel wrong no matter what the thermostat says.
Attic Insulation in West Hollywood
Most West Hollywood attics were never insulated to a modern standard, and many have been disturbed by decades of cable, plumbing and lighting work. When we handle Attic Insulation in West Hollywood, the first job is checking what’s actually up there: depth, condition, and whether the old material has settled or been compressed. In bungalows with low roof pitches, access is tight and the work is slow. In multi-unit buildings, we plan around occupied units below so ceiling penetrations get patched cleanly on the way out. The result is a steadier ceiling temperature and less strain on the air handler.
Spray Foam Insulation in West Hollywood
Spray foam earns its place in West Hollywood on the problem spots that loose fill can’t reach: rim joists, wall cavities behind plaster, and the odd gaps around old window frames. With Spray Foam Insulation in West Hollywood, we can use Icynene open-cell where sound control and vapor handling matter, or closed-cell where a thinner, denser barrier makes sense. In a rental building, the fact that foam both insulates and air-seals in a single pass means fewer trips through a tenant’s unit. It’s the material we reach for when the envelope needs to be tight, not just thicker.
Blown In Insulation in West Hollywood
Blown In Insulation in West Hollywood is usually a retrofit, not a new-build install. In a city where the buildings date from the 1920s to the 1950s and the attic was often left bare, loose fill is the least invasive way to build thermal mass into a cavity that already exists, and it handles the settling that plagues old batts. Our approach to Blown In Insulation is material-first: we pick the fill to fit the structure rather than forcing whatever is on hand into a lath-and-plaster bay.
Cellulose Insulation
Signs you need it
You feel the afternoon heat come straight through a ceiling, or the old attic fill has visibly settled below the joists.
What it costs in West Hollywood
Cellulose work in West Hollywood typically runs $1,200 – $3,500 for a blown-in job, and the written estimate sets the final price.
How we do it
We measure the existing depth, seal the obvious air paths, then blow the cellulose in evenly to the target depth and cap it with a depth marker so the coverage is verifiable later.
Blown In Fiberglass Insulation
Signs you need it
The attic has fiberglass that’s matted, damp-smelling, or was compressed by old ductwork and no longer holds its loft.
What it costs in West Hollywood
Fiberglass blown-in for a West Hollywood home typically estimates in the $1,200 – $3,500 range, with the written quote standing as the final figure.
How we do it
We remove the failed material where it’s gone flat, verify the cavity is dry, and blow fresh fiberglass in behind a baffle system so eave ventilation stays open.

Can you add blown-in insulation to a lath-and-plaster West Hollywood bungalow without tearing out walls?
Yes, in most cases. We blow fill through small openings rather than opening the wall, then patch and finish each hole. In a bungalow, that keeps the original plaster intact while still building a real thermal barrier.
How long does a blown-in insulation job take in West Hollywood?
Most attic blow-in work is a one-day job. Multi-unit buildings or homes that need old material removed first can run longer. Call (866) 942-5951 and we’ll give you a realistic window with your free estimate.

Material choice matters too, since spray foam and mineral wool cost more than fiberglass or cellulose. We give you an upfront, written price before any work starts, and that written estimate is what you pay.

What West Hollywood 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."
- Shannon Kowalski"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
- Amit Rao"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
