Insulation Company in Century City, CA
Blown in insulation is the workhorse retrofit for Century City’s high-rise condos and office towers, where getting material into existing wall cavities and mechanical chases matters more than laying batts across an open attic. Most of the jobs we do in the 90067 ZIP happen inside concrete-and-steel buildings from the 1960s through the 1980s, which means access is tight, party walls matter, and the installer’s equipment has to work around occupied units. Laguna Hills Insulation has served Century City since 2014, and we carry the full range of blown-in material options – fiberglass, cellulose, and mineral wool – so the right product wins the job, not the one easiest to haul up an elevator. Call us at (866) 393-6041 for a straight answer on what your building actually needs.
Why Century City Homes Are Different
Century City is a vertical business district built on the old 20th Century Fox backlot, and that origin story shapes nearly every insulation job we take on here. You are not dealing with pitched roofs, attics, or crawlspaces. You are dealing with mid- and high-rise towers where the insulation problems live inside party walls, mechanical shafts, chase ways, and the roof deck assemblies above the top-floor units. The building stock in 90067 is mostly 1960s-to-1980s concrete floor slabs with punched-window facades and centralized HVAC. That means the classic single-family-home insulation playbook does not apply.
The climate does not push heating and cooling loads the way it does in the Valley. Century City sits in a mild, marine-influenced pocket of the Westside, so what actually bothers people is the afternoon sun hammering west- and south-facing glass, plus the constant hum of Santa Monica Boulevard and the 405 corridor a few blocks north. Radiant-heat gain and acoustic leakage drive more calls here than a high heating bill ever will. Around Century Park East and Century Park West, the party walls between units are frequently thin and under-insulated, so noise complaints – footfall, voices, television – are the real reason most condo owners pick up the phone.
Fire rating matters more in Century City than almost anywhere else we work. When you add insulation inside a high-rise party wall or mechanical chase, the material has to work within a fire-rated assembly that was engineered decades ago. That is why we stock Rockwool alongside fiberglass and cellulose. Mineral wool gives you sound control, thermal performance, and fire resistance in one product, which is the combination these buildings need.
Our Main Century City Services
Two services handle most of what Century City condo owners and property managers call us about: attic insulation for the handful of penthouse and roof-level spaces that have real ceiling assemblies, and spray foam for the air-sealing and chase work that high-rises demand.
Attic Insulation in Century City
True attic spaces are rare in Century City, but they exist: penthouse units, mechanical penthouses, and a few low-rise structures at the district’s edge carry ceiling assemblies that lose conditioned air through the roof. When attic work is needed here, it usually centers on top-floor comfort complaints and HVAC duct runs that pass through unconditioned space. The mild marine climate means attics are not oven-hot like inland properties, but radiant heat from a flat roof deck still pushes into the unit below. We’ll assess what is actually up there and quote the right material rather than defaulting to whatever is easiest to drop in. See Attic Insulation in Century City for the full breakdown.

Spray Foam Insulation in Century City
Spray foam earns its keep in Century City wherever air leakage and sound travel through irregular cavities – mechanical chases, pipe penetrations between floors, gaps around window frames in punched-wall facades, and the odd soffit or bulkhead. Closed-cell foam from Demilec or Icynene acts as both an air barrier and a thermal barrier in a single pass, which is valuable when the cavity you are treating is only a few inches deep. Condo retrofits here rarely have room for thick insulation, so performance per inch matters. We also use open-cell foam where the priority is sound deadening inside interior walls and ceilings.

Blown In Insulation in Century City
Blown in insulation is the most practical way to get real thermal and acoustic performance into the existing walls of Century City’s high-rise condos without tearing everything apart. In the condo towers around Century Park East and West, party walls between units are frequently thin and poorly insulated, so noise complaints – conversation, television, heel strikes on hard flooring – drive many of the insulation jobs we perform. Mild Westside temperatures mean you are not chasing a huge heating bill, but the afternoon sun on west- and south-facing glass still pushes radiant heat through exterior walls, and blown-in material is the least disruptive fix when the drywall is already up. We work across blown-in fiberglass, cellulose, and mineral wool options, which lets us match the product to the fire-rating and sound requirements of your specific building rather than forcing one material into every job.

Cellulose Insulation
Signs you need it
You hear conversations or television through a party wall, your unit feels drafty near exterior walls, or your energy use climbs even though you have not changed how you live.
What it costs in Century City
Dense-packed cellulose in existing walls typically runs $1.50 to $3.50 per square foot in Century City, with the final number driven by access and the condition of the wall cavities.
How we do it
We drill small access holes at the top or bottom of each stud bay, blow the cellulose in at the correct density with a calibrated machine, then seal and patch the openings.
Blown In Fiberglass Insulation
Signs you need it
Your unit sweats in summer near the west glass, or the wall cavities between you and your neighbor are empty and echo when knocked on.
What it costs in Century City
Blown-in fiberglass for wall retrofits and mechanical chases generally lands between $1.20 and $3.00 per square foot in Century City, with high-rise access and prep adding to the base figure.
How we do it
We use a blowing machine to feed loose-fill fiberglass through a hose into the target cavity at the manufacturer’s specified density, working from a lift or scaffold where the opening is above floor level.
Loose Fill Insulation
Signs you need it
An existing cavity or roof assembly has settled or compacted insulation that no longer reaches the top of the space, leaving a band of uninsulated area.
What it costs in Century City
Loose fill installed flat across a terrace deck or between floor slabs usually costs $1.00 to $2.50 per square foot in Century City, varying with depth and material choice.
How we do it
We blow the loose fill evenly across the target surface to the required depth, using depth markers to hold the R-value consistent from edge to edge.
What Blown In Insulation Costs in Century City
| Item | Typical range in Century City |
|---|---|
| Blown-in fiberglass (wall retrofit) | $1.20 – $3.00 per sq ft |
| Dense-packed cellulose (party wall) | $1.50 – $3.50 per sq ft |
| Loose fill (flat deck / slab) | $1.00 – $2.50 per sq ft |
How long does blown in insulation last in a Century City condo?
Fiberglass and mineral wool last the life of the building when kept dry. Cellulose can settle slightly over 15 to 20 years, so we dense-pack it to reduce that. Call (866) 393-6041 and we will inspect what you currently have before recommending anything.
Can you blow insulation into a party wall without disturbing my neighbor?
Yes. We work from one side of the wall only, drill small access holes in your unit, and seal them the same day. If wall access is only possible on the neighbor’s side, we will coordinate that with your HOA. Call (866) 393-6041 to schedule an assessment.
Brands We Service in Century City

Because we stock across multiple manufacturer lines, we are not pushing a single brand on every Century City job.
