Insulation Company in West Hollywood, CA
Blown in insulation solves a problem West Hollywood knows well: older walls with nothing in them. Most of 90069’s housing stock went up between the 1920s and 1980s, and a large share of those walls never got insulated at all. That’s why our West Hollywood work leans heavily on retrofit blown-in jobs, not new construction. We work from eight manufacturer brands, so the recommendation matches the building, not the truck. Call home office at (877) 352-4780 for a free estimate.
Why West Hollywood Homes Are Different
West Hollywood insulation work is dominated by rental and multi-family stock. A large share of 90069 is apartment buildings and older single-family homes in the flats between Santa Monica Boulevard and Melrose. That means insulation jobs here are almost always retrofits inside occupied, rent-controlled units rather than clean new builds. The city’s green building goals and rent-stabilization ordinance make insulation a landlord-sensitive, tenant-occupied retrofit problem, not a typical suburban attic job.
The housing itself adds another layer. The Norma Triangle and hills still hold 1920s-to-1940s Spanish Colonial and bungalow single-family homes, many with knob-and-tube-era plaster walls and no exterior wall insulation. The flats are dense with 1960s-to-1980s low-rise apartments, most with flat roofs and no attic access at all. On those buildings, adding insulation means working on roof decks or inside walls, and coordinating with tenants and rent-stabilization rules on any unit downtime. Mild Mediterranean weather keeps heating and cooling loads modest, but west-facing walls and uninsulated flat roofs bake during fall Santa Ana heat events. Radiant-heat control and roof-plane insulation matter more here than cold-weather R-value.
Our Main West Hollywood Services
Two services get the most calls from West Hollywood homeowners and property managers. Both are covered in depth on their own pages.
Attic Insulation in West Hollywood
In the Norma Triangle and hillside bungalows, shallow attics and roof-deck-adjacent spaces are common. Older homes often have a thin layer of settled fiberglass or nothing at all. We assess what’s there, check ventilation, and recommend the right material for a roof plane that gets direct sun during Santa Ana events. For the full breakdown, see Attic Insulation in West Hollywood.
Spray Foam Insulation in West Hollywood
Flat-roofed 1960s apartments with no attic access often benefit most from spray foam applied to the roof deck or wall cavities. We carry both Icynene and Demilec systems, so open-cell or closed-cell chemistry is matched to each building’s moisture, R-value, and budget needs. For specifics on how spray foam handles West Hollywood’s building types, see Spray Foam Insulation in West Hollywood.

Blown In Insulation in West Hollywood
Blown in insulation is the workhorse for West Hollywood’s older walls. Homes built in the 1920s through the 1940s in the Norma Triangle and near the hills often have empty wall cavities behind plaster, and the only practical way to fill them without tearing out the plaster is blowing insulation in through small access holes. Our crews do this regularly in occupied units across 90069. We source blown-in materials from brands like Johns Manville, Knauf, and CertainTeed, so you get the right fill for your cavity depth and moisture conditions. Learn more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Rooms that overheat on fall Santa Ana days, especially on west-facing walls, often point to empty wall cavities behind the plaster.
What it costs in West Hollywood
Cellulose wall cavity fills in West Hollywood typically run $1.50 to $3.50 per square foot of wall area.
How we do it
We drill small access holes through the plaster or siding, blow the cellulose in to the correct density, then patch the holes cleanly.
Blown In Attic Insulation
Signs you need it
An attic floor with a thin, settled layer of old fiberglass or bare spots means the ceiling below is losing cooling to the roof plane.
What it costs in West Hollywood
Blown-in attic insulation in West Hollywood generally costs $1.00 to $3.00 per square foot of attic floor.
How we do it
We air-seal visible bypasses first, then blow the insulation to the target R-value across the entire attic floor, keeping soffit vents clear.
Blown In Fiberglass Insulation
Signs you need it
High cooling bills in a flat-roofed apartment or older home with accessible attic space often trace back to under-insulated ceilings.
What it costs in West Hollywood
Blown-in fiberglass in West Hollywood typically ranges from $0.80 to $2.50 per square foot of coverage area.
How we do it
We blow the fiberglass in loose and level, using the right pounds-per-square-foot to reach the specified R-value without over-compacting.

| Blown-in fiberglass (attic floor) | $0.80 – $2.50 per sq ft |
| Blown-in cellulose (attic floor) | $1.00 – $3.00 per sq ft |

Can you blow insulation into walls without removing the plaster?
Yes. We drill small access holes through the plaster or exterior siding, blow the material into the cavity, then patch the holes. Most West Hollywood wall retrofits are done this way without disturbing the original 1920s-to-1940s plaster.
How long does a blown-in wall retrofit take in a West Hollywood apartment?
Most single-unit wall retrofits finish in one day. Units stay habitable throughout, which matters in rent-controlled buildings where downtime triggers paperwork. Call (877) 352-4780 for a timeline specific to your building.
