Insulation Company in West Hollywood, CA
Blown in insulation solves a problem most West Hollywood homeowners don’t discover until August: an unconditioned attic turning the living space below into an oven. We install loose-fill cellulose and fiberglass in the tight, awkward cavities of 1920s bungalows and 1960s apartment buildings across 90069, often where batts simply can’t fit. The density control matters here. West Hollywood’s Blown In Insulation work requires precise installation to avoid settling voids behind lath-and-plaster walls. Call (866) 566-0304 for an estimate that accounts for your building’s actual framing, not a generic square-footage guess.
Why West Hollywood Homes Are Different
West Hollywood packs roughly 35,000 people into 1.9 square miles. That density shapes every insulation decision. Most homes date to the 1920s through 1940s: single-story bungalows and duplexes with original knob-and-tube era framing, minimal attic clearance, and zero lot lines that leave barely a foot between neighboring structures. Rent-controlled multi-family buildings add another layer. Under WeHo’s rent stabilization ordinance, owners scheduling insulation work in occupied units need to coordinate tenant access and justify the upgrade through the city’s process. We’re used to that paperwork and the staging constraints that come with it.
The climate works differently here than in the Valley. Hot, dry summers bake flat-roof additions and enclosed sunrooms. Winter brings the marine layer, and with it condensation that settles into uninsulated wall cavities. Blown-in insulation done right controls both. Done wrong, with uneven density, it creates exactly the settling voids that leave rooms hot in July and damp in January. We inspect what’s actually inside your walls before recommending anything.
Our Main West Hollywood Services
West Hollywood homeowners call us most often about two things: attics that radiate heat into the rooms below, and walls and roof decks where air-sealing matters as much as insulation. Both are jobs where the product choice depends on the building.
Attic Insulation in West Hollywood
Most prewar West Hollywood attics have less than three feet of headroom at the peak, which rules out a lot of standard installation approaches. Flat-roof additions complicate things further because there’s often no accessible attic at all, just a shallow ceiling cavity or a roof deck that needs insulation from the top. Attic Insulation in West Hollywood is the service page where we break down how we handle these specific conditions. We focus on the attic because that’s where most of the heat gain in a West Hollywood summer actually originates.
Spray Foam Insulation in West Hollywood
When an enclosed sunroom or flat-roof addition sits over living space, spray foam is often the only product that both insulates and air-seals in one pass. Closed-cell foam from Demilec adds structural rigidity to older framing, which matters in 1920s bungalows with undersized joists. Spray Foam Insulation in West Hollywood covers the options in detail. We carry Icynene open-cell where ventilation matters and Demilec closed-cell where moisture protection is the priority.
Blown In Insulation in West Hollywood
Blown in insulation works in places where batts simply can’t reach. In West Hollywood, that’s most pre-1940 walls, enclosed sunroom floors, and the shallow attics above low-rise apartments. We blow loose-fill material through small access holes, filling irregular cavities around original framing without tearing out lath and plaster. That’s the service we provide through our Blown In Insulation team, and it’s the most common request from homeowners in 90069 who have tried and failed to get batts into their aging buildings.
Cellulose Insulation
Signs you need it
Rooms that overheat by midafternoon even with windows open often mean the wall cavities between lath-and-plaster and exterior stucco were never insulated, and blown cellulose is the fix.
What it costs in West Hollywood
Cellulose insulation in West Hollywood typically runs $0.85 to $1.50 per square foot for wall cavities and attics, depending on the density required and the access conditions inside 1920s framing.
How we do it
We drill small pilot holes through plaster or stucco, snake a hose into each stud bay, and blow GreenFiber cellulose at controlled density so it fills every void without settling over time.
Blown In Attic Insulation
Signs you need it
Bedrooms directly under the roof running ten degrees hotter than the floor below is the classic signal that attic insulation has settled or was never adequate in the first place.
What it costs in West Hollywood
Blown-in attic insulation in West Hollywood ranges from $1.00 to $1.75 per square foot, with the higher end reflecting low-clearance attics that need hand work rather than machine blowing.
How we do it
We air-seal the attic floor first, then blow loose-fill insulation to the target R-value, working around original lath-and-plaster ceilings and any knob-and-tube era wiring still present.
What Blown In Insulation Costs in West Hollywood
| Item | Typical range in West Hollywood |
|---|---|
| Cellulose insulation (walls and attics) | $0.85 – $1.50 per sq ft |
| Blown-in attic insulation | $1.00 – $1.75 per sq ft |
| Air-sealing before blown-in install | $0.30 – $0.50 per sq ft |
Is blown in insulation worth it in West Hollywood’s climate?
Yes, for most prewar homes. The dense, hot summers mean heat pours through uninsulated walls and ceilings, and the damp winters create condensation that degraded older insulation. Blown-in at correct density fixes both. Call (866) 566-0304 for a site-specific assessment.
Can you blow insulation into walls without tearing them open?
Usually yes. We drill through plaster or stucco from the exterior or interior, blow the material in, patch the holes, and the wall is intact. Older West Hollywood bungalows respond well to this approach. Call (866) 566-0304 to find out if your walls qualify.
Brands We Service in West Hollywood
We stock and install from our brands including Owens Corning, Johns Manville, and GreenFiber, keeping common cellulose and fiberglass products available locally for fast turnaround. Demilec spray foam products are ordered per job so you get fresh material, not warehouse leftovers.

We typically schedule initial assessments in West Hollywood within two to three business days. Emergency work, like a torn roof deck that needs immediate air-sealing, can often be prioritized. Call (866) 566-0304 and we’ll give you the earliest slot based on your block and building type.

Yes. We’re familiar with WeHo’s rent stabilization ordinance requirements and work with property owners to schedule tenant access, document the scope, and complete jobs with minimal disruption to occupied units. The process is more coordination than a single-family bungalow, and we handle it.
