Insulation Company in West Hollywood, CA
Blown in insulation is the workhorse retrofit for West Hollywood’s 1920s to 1950s stucco bungalows and courtyard apartments, most of which were built with zero wall cavity insulation. In the hillside streets north of Sunset, we routinely drill through multiple stucco layers to dense-pack cellulose or fiberglass into walls that have been empty for 70-plus years. If you’re tired of rooms that bake in August and chill in January, call Laguna Hills Insulation at (866) 393-6041 and we’ll tell you exactly what your walls need.
Why West Hollywood Homes Are Different
West Hollywood’s insulation work is dominated by its dense stock of 1920s to 1950s stucco-over-wood-frame bungalows and small apartment buildings, many with no wall cavity insulation at all and knob-and-tube wiring still buried inside. Retrofitting here means working around fragile plaster, old lath, and code-triggered rewiring, not just blowing batts into new construction. Most single-family homes and low-rise apartments in 90069 are original lath-and-plaster with low-pitch roofs and minimal attic space, which means dense-pack wall injection and attic air-sealing are the standard approach. The climate adds its own pressure: hot, dry summers make uninsulated stucco walls radiate heat for hours after sundown, while cool, damp winters create condensation risk inside wall cavities. Add in the steep hillside lots north of Sunset, and you have a city where every job is a custom retrofit, not a production install.
We’ve learned to work with West Hollywood’s quirks rather than fight them. Drilling through original stucco without cracking the texture requires the right bit speed and a steady hand. Finding knob-and-tube wiring mid-job means pausing, documenting, and coordinating before any insulation goes in. And patching stucco to match 90-year-old texture is a skill most insulation crews never learn. These are the details that separate a job done right from a job that looks done.
Our Main West Hollywood Services
Most West Hollywood homeowners call us about two things: keeping attic heat out of the living space and sealing building envelopes that leak air through every plaster crack and stucco seam. Here’s how each one works in this city.
Attic Insulation in West Hollywood
West Hollywood’s low-pitch roofs and minimal attic space make attic insulation a high-leverage upgrade in 90069. Many of these 1920s and 1950s homes have no more than a few inches of settled, compressed fiberglass from decades ago, which leaves the ceiling as a radiant heat panel all summer. We air-seal the attic floor first, then blow in fresh insulation to the depth that matches the home’s roof geometry and the homeowner’s budget. For details on materials, R-values, and what the job looks like in West Hollywood’s specific housing stock, see our Attic Insulation in West Hollywood page.
Spray Foam Insulation in West Hollywood
Spray foam earns its keep in West Hollywood’s hillside homes where roof decks sit directly above living space and there’s no traditional attic to insulate. Open-cell foam from Icynene or Demilec creates an air seal and thermal barrier in a single application, which matters when the ceiling is also the roof. Closed-cell foam adds vapor control, useful in stucco walls that see winter condensation. The material cost is higher than blown-in, but the air-sealing performance is a different category altogether. For a full breakdown of open-cell versus closed-cell in West Hollywood’s housing stock, read our Spray Foam Insulation in West Hollywood page.

Blown In Insulation in West Hollywood
Blown in insulation is the most practical retrofit option for West Hollywood’s 1920s to 1950s stucco bungalows and courtyard apartments because it’s the only method that can reach wall cavities without gutting lath-and-plaster walls. In a city where most original homes have empty wall cavities, dense-packed cellulose or fiberglass turns a thermal sieve into a conditioned envelope, one stud bay at a time. And because West Hollywood’s summers punish uninsulated walls, the comfort return shows up in the first heat wave after the install. We’ve been blowing insulation into West Hollywood walls since 2014, and the single most important thing homeowners want to know is whether their walls can even take insulation. In most 90069 homes, the answer is yes, as long as any knob-and-tube wiring gets addressed first. For a broader look at the method and materials, our Blown In Insulation hub covers the complete picture.
Cellulose Insulation
Signs you need it
Rooms that get noticeably colder in winter and hotter in summer, especially in original stucco homes, usually point to empty wall cavities that cellulose can fill.
What it costs in West Hollywood
Cellulose wall dense-pack in West Hollywood typically runs $1.10 to $1.60 per square foot of wall area, making it the most cost-effective dense-pack material available.
How we do it
We drill small access holes through the stucco at each stud bay, blow in GreenFiber cellulose to a dense-pack pressure that prevents settling, then patch and texture-match each hole to the surrounding stucco.
Blown In Attic Insulation
Signs you need it
If your second-floor ceiling feels warm to the touch on summer evenings or your AC runs constantly despite a mild outdoor temperature, your attic insulation has likely compressed or was never adequate in the first place.
What it costs in West Hollywood
Attic blown-in insulation in West Hollywood generally ranges from $1.10 to $2.45 per square foot of attic floor, depending on material and the depth needed to hit the right R-value.
How we do it
We start by air-sealing the attic floor penetrations, then blow in Owens Corning fiberglass or GreenFiber cellulose to a uniform depth across the entire attic floor, including over existing settled insulation where appropriate.
Blown In Cellulose Insulation
Signs you need it
Homes with original plaster walls and no evidence of any retrofit work since construction are the strongest candidates for blown-in cellulose in West Hollywood.
What it costs in West Hollywood
Blown-in cellulose for attic or wall applications in 90069 falls between $1.10 and $1.60 per square foot, with dense-pack wall injection running toward the upper end of that range.
How we do it
We load GreenFiber cellulose into our blowing machine, run the hose to each access point, and dense-pack the material until it reaches the pressure spec that guarantees no future settling.
Blown In Fiberglass Insulation
Signs you need it
If you’re topping up an existing attic that already has some fiberglass but not enough depth, blown-in fiberglass blends with what’s there and brings the R-value up quickly.
What it costs in West Hollywood
Blown-in fiberglass in West Hollywood typically costs $1.10 to $2.45 per square foot depending on the target R-value and whether it’s a top-up or a fresh install.
How we do it
We blow Owens Corning or Johns Manville loose-fill fiberglass across the attic floor in consistent passes, checking depth with a measuring stick at regular intervals until the specified R-value is reached.
Loose Fill Insulation
Signs you need it
Low-pitch roofs with shallow attic spaces, which describe many West Hollywood bungalows, often need loose fill blown into irregular and hard-to-reach areas where batts won’t fit.
What it costs in West Hollywood
Loose fill insulation in West Hollywood’s attics starts around $1.10 per square foot and can reach $2.45 per square foot when deep R-38 or R-49 coverage is specified.
How we do it
We run a hose through the attic and blow loose-fill material into every corner, around obstructions, and over existing framing until the entire attic floor is uniformly covered to target depth.
What Blown In Insulation Costs in West Hollywood
| Item | Typical range in West Hollywood |
|---|---|
| Cellulose wall dense-pack | $1.10 – $1.60 per sq ft of wall area |
| Blown-in attic insulation | $1.10 – $2.45 per sq ft of attic floor |
| Blown-in fiberglass top-up | $1.10 – $2.45 per sq ft depending on depth |
Can you blow insulation into walls that have knob-and-tube wiring?
No. Blown-in insulation must never contact live knob-and-tube wiring, which is common in West Hollywood’s 1920s homes. The wiring must be decommissioned and replaced by a licensed electrician before we can insulate those wall cavities.
How long does blown in insulation last in West Hollywood’s climate?
Cellulose and fiberglass both last the life of the home when installed correctly and kept dry. The only threat in West Hollywood is moisture intrusion through stucco cracks or roof leaks, which is why we inspect for water issues before blowing anything in.
Brands We Service in West Hollywood
We stock and install Owens Corning and Johns Manville fiberglass, Rockwool mineral wool, and GreenFiber cellulose, which means the right material gets chosen for each West Hollywood home rather than whatever single product line the contractor happens to carry. Parts for any repair or top-up are available locally within a day or two. Learn more on our brands page.
