Insulation Company in Hollywood, CA
Blown in insulation is the workhorse retrofit for Hollywood’s older apartment stock, and it’s the service we perform most often in the 90028 zip code. Most of these buildings went up between the 1920s and 1960s with no cavity insulation at all, so owners face brutal summer heat gain through walls and attic spaces that were never designed for modern AC loads. Even Air Insulation has served Hollywood since 2018, matching each building to the right material rather than pushing one product. Call (855) 362-0195 for a free estimate.
Why Hollywood Homes Are Different
Hollywood’s housing stock is not suburban tract homes. The dominant building types around 90028 are 1920s-era Spanish and Mediterranean courtyard apartments, wood-frame bungalows from the same period, and postwar stucco low-rises from the 1950s and 60s. Most share the same underlying problem: wood-frame walls, plaster interiors, and zero original cavity insulation. Some still carry knob-and-tube wiring in the walls, which changes how we approach blown-in work because loose fill cannot be packed around live knob-and-tube conductors safely.
The climate drives why insulation matters here. Hollywood runs warm and dry with long hot summers and mild winters. Insulation value in this market is about heat gain and AC cost, not freeze protection. Attic and flat-roof assemblies bake in direct summer sun, and uninsulated wall cavities radiate that heat into living spaces well after sunset. For renters in courtyard apartments off Hollywood Boulevard, the difference between an insulated unit and an uninsulated one shows up directly in the electric bill. Even Air recommends attic insulation as the highest-return energy upgrade most Hollywood buildings can make.
Our Main Hollywood Services
Hollywood homeowners and building owners call us most about two services: attic insulation and spray foam. Each one suits a different building condition, and we help you figure out which is right before any work begins.
Attic Insulation in Hollywood
For the courtyard apartments and low-rises that define Hollywood, attic insulation is usually the first move. Cramped, low-clearance attic spaces over plaster ceilings are common here, and they’re often the biggest source of heat gain in the whole building. We work in those tight spaces with blown-in materials that settle around existing framing without disturbing the plaster below. The long hot summers make this job matter more in Hollywood than in cooler parts of the county. Attic Insulation in Hollywood covers what to expect, what it costs, and how we handle older construction.
Spray Foam Insulation in Hollywood
Spray foam earns its keep in Hollywood when there’s an air-sealing problem along with a thermal one: flat-roof assemblies, band joists, crawl spaces, or walls where air moves freely through old framing. Through Icynene and Demilec product lines, we have access to both open-cell and closed-cell formulations, so the material can match the moisture and structural requirements of the space. Spray foam isn’t always the answer, but when it is, we have two professional-grade options. Spray Foam Insulation in Hollywood explains where foam fits and where blown-in makes more sense.

Blown In Insulation in Hollywood
Blown in insulation is the most common retrofit we perform in Hollywood because it’s the only practical way to fill existing wall and attic cavities without tearing out plaster. The 1920s courtyard apartments and 1950s stucco low-rises around 90028 were built with empty wall cavities, and in the summer those cavities act like heat channels, pulling hot air from sun-baked exterior walls into units all afternoon and evening. Blown-in loose fill, installed through small access holes, fills those voids and drops interior temperatures dramatically while cutting AC runtime. We carry GreenFiber cellulose and fiberglass options, and the right material depends on the wall assembly and whether knob-and-tube wiring is present. Blown In Insulation is a core part of what we do, and in Hollywood it’s the retrofit that pays for itself fastest.
Cellulose Insulation
Signs you need it
Walls that radiate heat after sunset and AC that runs constantly in summer point to empty wall cavities, which cellulose blown-in is ideal for filling.
What it costs in Hollywood
Blown-in cellulose in Hollywood typically ranges from $1.50 to $3.50 per square foot installed, depending on cavity depth and access.
How we do it
We drill small access holes through exterior or interior plaster, blow GreenFiber cellulose at the correct density, then patch and touch up the holes cleanly.
Blown In Attic Insulation
Signs you need it
Ceilings that feel warm to the touch by late afternoon and upstairs rooms that never cool down are classic signs of an under-insulated Hollywood attic.
What it costs in Hollywood
Blown-in attic insulation in Hollywood generally runs $1.50 to $3.50 per square foot installed, with the lower range for open attics and the higher for low-clearance work.
How we do it
We blow loose fill across the attic floor to the target R-value, working around the cramped framing and low clearances common in older Hollywood buildings.
What Blown In Insulation Costs in Hollywood
| Item | Typical range in Hollywood |
|---|---|
| Blown-in cellulose (walls) | $1.50 – $3.50 per sq ft |
| Blown-in attic insulation | $1.50 – $3.50 per sq ft |
| Loose fill in low-clearance attics | Toward the upper end of that range |
Is blown in insulation worth it for a Hollywood rental property?
Yes. In courtyard apartments with no cavity insulation, blown-in work cuts summer AC draw noticeably, which keeps tenants comfortable and reduces turnover complaints about hot units. Call (855) 362-0195 for an exact quote, estimates are free.
Can you blow insulation into walls with knob-and-tube wiring?
Generally no, and we will not blow loose fill around live knob-and-tube conductors. We inspect first; if that wiring is present in the target walls, we will discuss alternatives or the electrical work needed first.
