Insulation Company in West Hollywood, CA
Blown in insulation is the most practical way to retrofit West Hollywood’s older apartment buildings and bungalow courts, most of which were built before 1960 with no insulation in their walls or attics. Even Air Insulation specializes in dense-pack cellulose and loose-fill fiberglass that can be installed from the exterior, so tenants aren’t displaced and daily life continues uninterrupted. If you’re dealing with rooms that bake in the afternoon sun or walls that pass every neighbor’s conversation straight into your living room, call us at (855) 362-0195. We’ve served West Hollywood since 2018 and know exactly what these buildings need.
Why West Hollywood Homes Are Different
West Hollywood’s building stock creates insulation challenges you won’t find a few miles east. The 90069 ZIP is dominated by 1920s through 1960s multi-family apartments, many with original wood-frame walls, lath-and-plaster interiors, and zero insulation anywhere in the envelope. Add in the density: buildings sit wall-to-wall, so two units often share an uninsulated cavity that transmits sound and heat in both directions. That means insulation work here is as much about sound control as temperature control. Property owners face a real constraint too. Many of these buildings are rent-controlled, which means you can’t empty units for a gut renovation. The work has to happen in place, often by drilling from the exterior and blowing material into shared wall cavities. We plan every West Hollywood job around occupied units, tight access, and the need to leave tenants undisturbed.
The climate adds another layer. West Hollywood is mild, but south- and west-facing walls absorb serious afternoon sun from spring through fall. Older buildings without attic or wall insulation turn that solar gain into interior heat, and the lack of air sealing means whatever you cool leaks right back out. Blown-in retrofits, especially cellulose with its higher density, solve both problems in one pass.
Our Main West Hollywood Services
West Hollywood homeowners and property managers call us most often for two specific jobs: attics that need a full thermal barrier and walls or rim joists that need the air-sealing power of spray foam. Here’s how each one plays out in this city.
Attic Insulation in West Hollywood
Most pre-1960s buildings in West Hollywood have attics with either no insulation or a thin, settled layer of old fiberglass that stopped working years ago. The flat-roof and low-slope construction common here makes heat gain relentless in summer. We dense-pack or blow in fresh material across the attic floor, air-seal penetrations first, and bring the assembly up to current code levels. For full details on what this job looks like in 90069, see our dedicated page: Attic Insulation in West Hollywood.
Spray Foam Insulation in West Hollywood
When a West Hollywood building has an inaccessible wall cavity or a shared party wall that leaks air and sound, spray foam is often the only material that works. We apply open-cell foam where sound dampening matters most, and closed-cell foam where moisture or structural rigidity is the priority. Both products seal air movement completely, which is what aging multi-family buildings here need most. Learn more on the service page: Spray Foam Insulation in West Hollywood.

Blown In Insulation in West Hollywood
Blown in insulation is the retrofit workhorse for West Hollywood’s pre-1960s apartment stock. Because walls here were rarely insulated at construction, and because attics were built for ventilation rather than thermal performance, blowing material into existing cavities fixes both problems without opening interior walls. We install dense-pack cellulose (GreenFiber) and loose-fill fiberglass, matched to each cavity. For a full breakdown of the method, our Blown In Insulation hub walks through every detail.
Cellulose Insulation
Signs you need it
Rooms facing south or west run consistently hotter than the rest of the unit, or you hear conversations through walls that should be private.
What it costs in West Hollywood
Cellulose wall retrofits in West Hollywood typically run $1.60 – $3.20 per square foot of wall area, with attic applications ranging $0.90 – $1.60 per square foot.
How we do it
We drill small exterior access holes, dense-pack cellulose into every cavity at 3.5 lbs per cubic foot, then patch and paint-match the holes to disappear.
Blown In Attic Insulation
Signs you need it
Your cooling bill keeps climbing each summer and the ceiling below the attic feels warm to the touch by late afternoon.
What it costs in West Hollywood
Blown-in attic insulation in West Hollywood generally falls between $1,250 and $2,900 for a full attic in a typical bungalow court or small apartment building.
How we do it
We air-seal every penetration, install baffles to protect soffit ventilation, then blow material to the specified depth and density across the full attic floor.
What Blown In Insulation Costs in West Hollywood
| Item | Typical range in West Hollywood |
|---|---|
| Cellulose wall retrofit (per sq ft) | $1.60 – $3.20 |
| Attic loose-fill (per sq ft) | $0.90 – $1.60 |
| Full attic in a typical building | $1,250 – $2,900 |
These are the ranges we quote most often in 90069. Prices shift with access difficulty, cavity depth, and whether existing material needs removal first.
Does blown in insulation help with sound between West Hollywood apartments?
Yes. Dense-pack cellulose is one of the most effective materials for reducing sound transfer through shared wall cavities. We’ve measured noticeable reductions in noise transmission after retrofitting party walls in buildings throughout West Hollywood, where the uninsulated shared cavities are common.
Can you install blown in insulation without tenants moving out in West Hollywood?
Yes, that’s how we handle nearly every rent-controlled building in West Hollywood. We access wall cavities from the exterior, work room by room if needed, and keep the interior untouched. The process is quiet enough that tenants stay in place. Call (855) 362-0195 to talk through your building’s layout.

What West Hollywood Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Andres Vargas"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Daniela Martinez"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."
