Insulation Company in West Hollywood, CA
Blown in insulation solves a problem most West Hollywood homeowners know too well: rooms that bake in summer and never quite warm up in winter because the original walls and attic were never insulated, or the old fill has settled into a thin, nearly useless layer. West Hollywood’s 1920s and 1930s bungalows and Spanish Colonial homes were built long before Title 24 energy standards existed, and many still have empty stud cavities or the original paper-faced batts, now degraded. North Tustin Insulation has served West Hollywood since 2011, matching the right blown-in material – GreenFiber cellulose or Johns Manville fiberglass – to each home’s specific construction.

Why West Hollywood Homes Are Different
West Hollywood’s housing stock reads like a timeline of Southern California building history, and each era brings its own insulation realities. The oldest homes – mostly 1920s to 1940 wood-frame bungalows and Spanish Colonial revivals in the Norma Triangle and West Hollywood Heights – were built with empty wall cavities or, at best, a thin layer of paper-faced batt that has long since compacted. Many still wear their original red clay tile roofs, installed without underlayment or attic ventilation, which means attic temperatures climb fast and any insulation work requires careful air-sealing first. On the other side of the spectrum, the 1950s and 60s garden-style apartment buildings scattered through the city’s flatter central blocks have flat roofs, exposed ceiling joists, and wall assemblies that were minimally insulated from the start. Mixed-use buildings along Santa Monica Boulevard and Sunset Boulevard add commercial insulation needs to the residential mix. Add in the semi-arid Mediterranean climate – mild, wet winters and hot, dry summers – and the reality is that West Hollywood rarely freezes, so pipe insulation is not the priority. Attic and wall insulation are what actually cut summer heat gain and keep cooling bills manageable. The city rarely freezes, so pipe insulation is not a priority, but attic and wall insulation are critical for summer heat gain and for staying on the right side of Title 24 when any reroof or HVAC replacement is permitted. Technicians here work on tight, zero-lot-line properties where the neighboring wall may be inches away, and any exterior work visible from the street can trigger a historic-preservation review – so the job has to be done right the first time, from the inside, without disturbing protected facades.
Our Main West Hollywood Services
Most West Hollywood calls to us start with one of two situations: an attic that is effectively uninsulated and baking the rooms below, or a homeowner who wants the air-sealing power of spray foam in a city where older construction leaks air constantly. Here is how each service works in West Hollywood specifically.
Attic Insulation in West Hollywood
Attic work in West Hollywood often means dealing with what is already up there: compacted cellulose, bare rafters, or nothing at all under an original clay tile roof with no ventilation. Our team air-seals first, addresses any degraded material, then installs the right system – fiberglass batts, blown-in cellulose, or a combination – sized for the actual roof assembly, not a generic square-footage formula. The goal is a cooler house in summer and a ceiling that does not radiate heat into the living space by 4 p.m. We carry Owens Corning and CertainTeed fiberglass, plus GreenFiber cellulose, so the material recommendation follows the home’s construction. Learn more on our dedicated Attic Insulation in West Hollywood page.
Spray Foam Insulation in West Hollywood
Spray foam earns its place in West Hollywood’s older, leaky homes by doing two jobs at once: insulating and air-sealing. In 1920s Spanish Colonial bungalows with empty wall cavities and no house wrap, open-cell spray foam can fill the cavity completely and stop the air movement that fiberglass cannot address on its own. In the flat-roofed 1950s apartment buildings, closed-cell foam adds thermal resistance in shallow rafter bays where batt insulation would be pressed thin. We install both Icynene and Demilec spray foam systems, which means we are not limited to one product line or one open-cell-only approach. See the full breakdown on our Spray Foam Insulation in West Hollywood page.

Blown In Insulation in West Hollywood
Blown in insulation is the workhorse solution for West Hollywood’s older housing stock because it is the only practical way to add insulation to existing walls and attics without tearing out finished surfaces. In a 1920s Norma Triangle bungalow with lath-and-plaster walls and no cavity insulation, blowing in cellulose or fiberglass through small access holes puts insulation where there has never been any. In a 1950s garden apartment with a flat roof and exposed ceiling joists, blown-in attic insulation can bring the thermal barrier up to current code without structural changes. We match the material to the home – GreenFiber cellulose for dense-pack wall work, Johns Manville fiberglass for open attics – so the recommendation comes from the building, not the truck. This is the core of our Blown In Insulation service, and in West Hollywood it is the repair many of these old houses have been waiting on for 90 years.
Cellulose Insulation
Signs you need it
Rooms that never hold temperature, walls that feel warm to the touch in summer or cold in winter, and utility bills that climb every August point to wall cavities with no effective insulation – exactly what GreenFiber cellulose dense-packed into those old stud bays can fix.
What it costs in West Hollywood
Dense-packed cellulose wall insulation in West Hollywood typically runs $2.50 to $4.50 per square foot of wall area, including the drilling, filling, and patching required on stucco-sided bungalows.
How we do it
We drill access holes through the exterior stucco or interior lath and plaster, dense-pack GreenFiber cellulose to the correct pounds-per-cubic-foot density so it will not settle, then patch the holes to match the existing finish.
Blown In Attic Insulation
Signs you need it
If your upstairs rooms are 8 to 12 degrees hotter than the rest of the house in summer, or you can see bare joists and old, flattened insulation up there, your attic is doing almost nothing to stop heat from radiating down through the ceiling.
What it costs in West Hollywood
Blown-in attic insulation in West Hollywood typically costs $1.50 to $3.50 per square foot of attic floor, with most 1,000-square-foot attics landing between $1,500 and $3,500 before any air-sealing work.
How we do it
We remove or assess any degraded existing material, air-seal penetrations and top plates, then blow Johns Manville fiberglass or GreenFiber cellulose to a consistent depth across the entire attic floor, including under the eaves where heat sneaks in first.
Loose Fill Insulation
Signs you need it
Older homes in West Hollywood with open attic spaces, low-slope roofs, or finished walls that need insulation without demolition are prime candidates for loose fill material that flows into every corner and odd-shaped bay.
What it costs in West Hollywood
Loose fill insulation in West Hollywood generally runs $1.50 to $3.50 per square foot for open attics, while wall cavity work with dense-packed loose fill starts higher due to access and patching labor.
How we do it
We run hoses from our truck-mounted blower to the attic or wall access point and fill the cavity at the specified density for the material and application, checking depth and coverage as we go rather than guessing by bag count.
What Blown In Insulation Costs in West Hollywood
| Item | Typical range in West Hollywood |
|---|---|
| Blown-in attic insulation | $1.50 – $3.50 per sq ft |
| Dense-packed wall insulation | $2.50 – $4.50 per sq ft |
| Whole-home wall and attic package | $4,000 – $8,000 |
How long does blown in insulation last in West Hollywood’s climate?
Cellulose installed at the correct density will perform for decades without settling, and fiberglass holds its R-value indefinitely when kept dry. In West Hollywood’s semi-arid climate, moisture is rarely the issue – the bigger risk is old insulation that was never installed to spec in the first place.
Do I need to remove old insulation before blowing in new material?
Not always. We assess the existing material first: if it is dry, uncontaminated, and not overly compacted, new loose fill can go on top. When we find degraded, vermin-soiled, or severely compacted fill – common in 1920s attics – removal and air-sealing come first.
