Insulation Company in Glendale, CA
Most Glendale homes were never insulated for the summers we actually get. We’re talking 1920s Spanish Colonials and 1950s tract houses built when cooling meant opening a window and hoping for a breeze. Now those same attics hit 140°F by early afternoon, and south- and west-facing rooms bake into the evening. Hollywood Insulation Co specializes in blown in insulation for exactly this housing stock: older attics, lath-and-plaster walls, and tight access that makes retrofit work delicate. We’re a pure-play insulation contractor serving Glendale since 2018, and we match the material to the home, not the other way around. Call (866) 605-6949 for a free estimate.
Why Glendale Homes Are Different
Glendale’s housing stock is a mix of 1920s-40s Spanish Colonial and Craftsman bungalows, post-war 1950s-60s tracts, and dense mid-century apartment buildings. Many of these homes have low-pitch attics, original lath-and-plaster or early drywall, and knob-and-tube-era wiring that has to be worked around before anything gets blown in. The insulation challenge here isn’t cold winters. It’s the San Fernando Valley sun. A Glendale attic in July acts like a heat sponge, radiating warmth down through the ceiling for hours after sunset. That’s why the real value in Glendale is fighting summer attic heat gain and cutting the late-afternoon sun load that bakes rooms across the Verdugo foothill neighborhoods. Seasonal wildfire smoke and ash make air-sealing and dust exclusion genuinely valuable too. A home that leaks outside air pulls in smoke, dust, and pollen through every crack in the ceiling. Retrofitting older Glendale homes means sealing those bypasses before adding insulation, because insulation alone won’t fix an air leak.
Our Main Glendale Services
Most Glendale homeowners reach out about two things: an attic that’s turning the upstairs into a sauna, or drafty rooms that never hold a consistent temperature. Both of these have dedicated service pages below.
Attic Insulation in Glendale
Attic insulation in Glendale is almost always a heat-rejection project, not a heating-season upgrade. We inspect the existing batt or blown-in material, check for air bypasses around recessed lights and plumbing penetrations, and recommend the right thickness or replacement material for a cooling-dominated climate. Older Glendale homes often have compressed fiberglass from decades ago that’s doing almost nothing. We work around knob-and-tube wiring and shallow rafter bays on a regular basis. For the full breakdown of attic work in this area, see Attic Insulation in Glendale.
Spray Foam Insulation in Glendale
Spray foam in Glendale solves a specific problem: air leakage through low-pitch attic ceilings and uninsulated wall cavities in 1940s bungalows. Closed-cell foam from Demilec or Icynene systems gives you both R-value and an air seal in one pass, which matters when Santa Ana heat spikes push temperatures past 100°F. We use open-cell where sound control matters more, like apartments on busy corridors. For specifics on foam performance and pricing in this market, see Spray Foam Insulation in Glendale.

Blown In Insulation in Glendale
Blown In Insulation is the most common retrofit we install in Glendale because it works with the housing stock we actually have. Older attics with odd rafter spacing, shallow cavities, and knob-and-tube wiring welcome a material that flows around obstacles rather than fighting them. In a city where summer attic heat gain is the main enemy, a properly air-sealed blown-in installation keeps conditioned air where it belongs and rejects the afternoon sun load far better than old, compressed batts.

Your attic floor is covered in thin, settled material that measures under R-19, or you feel ceiling heat radiating into upstairs rooms by mid-afternoon.
What it costs in Glendale
Cellulose attic insulation in Glendale typically runs $1.50 to $3.50 per square foot depending on depth and access.
How we do it
We air-seal ceiling penetrations first, then dense-pack or loose-fill recycled cellulose to the specified R-value using a two-person hose crew.

What Blown In Insulation Costs in Glendale
| Item | Typical range in Glendale |
|---|---|
| Blown in attic insulation (full install) | $1,800 – $3,600 |
| Cellulose insulation (per sq ft) | $1.50 – $3.50 |
| Blown in fiberglass (per sq ft) | $1.00 – $2.50 |
Is blown in insulation worth it for Glendale summers?
Yes. Most Glendale attics are under-insulated for a cooling climate, so blown in insulation reduces heat gain through the ceiling and lowers AC run time. You’ll feel the difference in south- and west-facing rooms by the next heat wave.

Most attic jobs wrap up in one day, including air-sealing and cleanup. We schedule around your day and confirm an arrival window before we show up. Call (866) 605-6949 to check availability this week.
