Insulation Company in Glendale, CA
Blown in insulation does the heavy lifting in Glendale, where most homes went up between the 1920s and 1970s with thin or missing attic coverage. We’re Even Air Insulation, and we specialize in retrofitting older Glendale homes with loose-fill cellulose and fiberglass that stops the Verdugo foothill heat from turning attics into ovens. Call (855) 362-0195 for an estimate on bringing your home’s thermal barrier up to what Glendale summers actually demand.
Why Glendale Homes Are Different
Glendale isn’t a new-construction market. The housing stock is a dense mix of 1920s Craftsman bungalows, Spanish-Revival homes, mid-century stucco tract houses, and postwar apartment buildings in the lower flats. Most of these were built before insulation was code, and many still carry only a few inches of old rock-wool or, in some cases, vermiculite that has settled to near-useless R-values. That means almost every job we do in Glendale is retrofit work, not new build. The attics in the older hillside bungalows below the Verdugos are frequently wide open, with no baffles, original knob-and-tube wiring in some cases, and rafters that have been baking under Santa Ana sun for 80 years. Before we can blow insulation into those spaces, we typically have to add rafter vents and air-seal the attic floor so the insulation actually performs. Glendale’s climate drives the decision making too: hot, dry summers and mild winters mean attic heat gain is the real enemy, not cold loss. A home with an uninsulated, unshaded roof on a 95 degree August day is paying a real penalty in cooling costs. The right blown in material, installed at the right depth, changes that.
Our Main Glendale Services
Glendale homeowners most often call us about two services: attic insulation and spray foam. Each has its own page for this city, and each solves a different set of problems depending on how your home is built and where the heat is coming in.
Attic Insulation in Glendale
The majority of older Glendale attics have fiberglass batts that were installed decades ago, compressed, disturbed by rodents, or never thick enough in the first place. We pull out what’s failed and replace it with the right product for the space, whether that’s blown in fiberglass for open attics or Rockwool batts where fire resistance and sound dampening matter. Some homes in the hillside zones need air-sealing first, since gaps around ceiling penetrations let hot attic air circulate straight down into living spaces. See our full breakdown at Attic Insulation in Glendale.
Spray Foam Insulation in Glendale
Spray foam isn’t always the answer, but when it is, we have two professional-grade options through Icynene and Demilec. Closed-cell foam makes sense in Glendale crawl spaces and rim joists where moisture and structural rigidity matter. Open-cell works well in cathedral ceilings and hard-to-reach cavities common in older hillside homes. Glendale’s hot attic problem is sometimes best solved with spray foam at the roofline rather than blown in on the attic floor, and we’ll walk you through which approach matches your house.

Blown In Insulation in Glendale
Blown in insulation in Glendale is usually the most cost-effective way to fix an underperforming attic in a single day. Most of the homes we see in the 91201, 91222, 91225, and 91226 ZIP codes were built with little or no attic insulation, and the ones that have some are often carrying old, settled material that no longer does its job. We blow in GreenFiber cellulose or loose-fill fiberglass at the depth your roof and budget call for, and we handle the prep work older Glendale attics require, from air-sealing to baffle installation. The goal is an attic that stops transferring Verdugo summer heat into your living space. That’s what our Blown In Insulation service does.
Cellulose Insulation
Signs you need it
Rooms get noticeably warmer by late afternoon even with the AC running, and your attic floor shows bare or settled patches below the rafters.
What it costs in Glendale
Cellulose insulation in Glendale attics typically runs $0.70 – $2.00 per square foot installed, depending on depth and prep work.
How we do it
We air-seal penetrations, install rafter baffles, then dense-pack or loose-fill the cellulose to the R-value your home needs, usually in a single visit.
Blown In Attic Insulation
Signs you need it
Your attic insulation is original to a home built before 1980, or it’s been displaced by wiring work, pests, or decades of settling.
What it costs in Glendale
Blown in attic insulation in Glendale generally falls between $1,300 and $3,400 for a typical 1,000 – 1,500 square foot attic.
How we do it
We prep the attic by sealing gaps and adding baffles, then blow the material to code depth with calibrated equipment so coverage is even wall to wall.
Blown In Cellulose Insulation
Signs you need it
You want a denser, recycled-content material that fills odd cavities and slows airflow better than loose fiberglass in older framing.
What it costs in Glendale
Blown in cellulose in Glendale runs $0.70 – $2.00 per square foot installed, with depth and existing material removal affecting the final number.
How we do it
We dense-pack wall cavities or loose-fill attic floors using GreenFiber cellulose, which has a higher R-value per inch than fiberglass and better air-blocking performance.
Loose Fill Insulation
Signs you need it
You have open attic floor cavities, odd joist spacing, or an older home where batts won’t sit properly without gaps.
What it costs in Glendale
Loose fill insulation in Glendale typically costs $1.75 – $2.75 per square foot installed for fiberglass, depending on depth and access difficulty.
How we do it
We prep the floor, mark target depth, and blow the fill uniformly so there are no thin spots or voids, then check coverage with a depth gauge before we leave.
What Blown In Insulation Costs in Glendale
| Item | Typical range in Glendale |
|---|---|
| Blown in attic insulation (full attic) | $1,300 – $3,400 |
| Cellulose attic blow-in | $0.70 – $2.00 per sq ft |

How long does blown in insulation last in Glendale?
Cellulose and fiberglass loose fill both last 20 to 30 years in Glendale attics before settling or moisture degradation starts cutting the R-value meaningfully. We check depth and density when we install so you’re starting at full performance. Call (855) 362-0195 for a free attic assessment.
Can you blow insulation into existing walls in Glendale?
Yes, dense-pack cellulose can be blown into the wall cavities of older Glendale homes through small exterior holes, which we patch after. It works well in 1920s and 1950s framing where there’s no wall insulation at all. Estimates are free, so call for a site check.
Brands We Service in Glendale
We install and service insulation from eight manufacturers, and for Glendale homes we lean on a few depending on the application: Rockwool for fire resistance and sound control in shared-wall and hillside homes, CertainTeed and Johns Manville for fiberglass, and Icynene and Demilec when spray foam is the right call. See our brands for the complete roster and material specs.

Glendale prices tend to climb when the attic has old vermiculite or rock-wool that needs identification and removal, when knob-and-tube wiring requires an electrician’s clearance before we blow, or when hillside access makes equipment setup slower. We quote a fixed price before any work starts, so the number we give you is the number you pay.

What Glendale 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."
