Insulation Company in Sherman Oaks, CA
Blown in insulation in Sherman Oaks is the most common fix for the mid-century homes that dominate this part of the Valley. Houses built between the 1940s and 1960s were rarely insulated to modern standards, and after decades of heat, the original fiberglass batts in many Sherman Oaks attics have compressed to a fraction of their intended thickness. We match each home to the right material, whether that’s loose fill cellulose for an older attic or a dense-pack fiberglass application, so rooms stop baking in summer and hold heat better during the Santa Ana season.

Why Sherman Oaks Homes Are Different
Sherman Oaks sits in a hot, dry San Fernando Valley pocket where summer attic temperatures routinely exceed 140°F. That changes the insulation conversation entirely. Most of the country worries about keeping heat in during winter. Here, the dominant problem is radiant heat pushing down through the ceiling from a superheated attic, which is why second-story rooms in older Sherman Oaks homes so often hover above 80°F even with the air conditioning running. Insulation here is as much about blocking heat gain and supporting attic ventilation as it is about R-value.
The housing stock tells the same story. Much of Sherman Oaks is mid-century tract and ranch housing from the 1940s through the 1960s, plus 1970s and 1980s two-story homes in the hills and along the boulevards. Many of those original attics still have R-11 fiberglass batts that have collapsed flat over the decades. The flat, gridded streets around Sunset Boulevard and Valley Vista are where we find the most dramatic cases: original insulation that’s now doing almost nothing, missing radiant barriers, and bedrooms that never cool below uncomfortable temperatures. These older homes were built long before modern energy codes, and their attics show it.
Our Main Sherman Oaks Services
Most Sherman Oaks homeowners call us about two things: attic insulation and spray foam. Both address the same core frustration, just through different methods and budgets.
Attic Insulation in Sherman Oaks
Attic insulation is the first place we look in Sherman Oaks because that’s where the heat fight happens. In a 1950s ranch near the boulevards, the attic is often the difference between a house that cools down and one that never quite gets there. We remove or supplement old, compressed batts, seal the gaps, and install the right material for the home’s construction and venting. For full details on how attic work plays out in Sherman Oaks, see our dedicated page on Attic Insulation in Sherman Oaks.
Spray Foam Insulation in Sherman Oaks
For two-story homes in the hills and along the canyon edges, spray foam is often the best answer. It seals the attic against both heat and air movement, which matters enormously in a climate with long, dry summers and Santa Ana wind events. Open-cell and closed-cell systems from Icynene and Demilec let us match the material to the attic’s geometry and the home’s venting. We wrote a full guide to the process here: Spray Foam Insulation in Sherman Oaks.

Blown In Insulation in Sherman Oaks
Blown in insulation in Sherman Oaks solves the problem that defines so many older Valley homes: attics with original insulation that has collapsed flat under years of heat. When a ranch or two-story Sherman Oaks house was built before modern energy codes, the attic often has R-11 fiberglass batts that now sit compressed and ineffective. Blown in insulation lets us fill the entire attic cavity evenly, including the odd bays and corners where batts never quite reached, so the home finally holds its temperature. Blown In Insulation is our most requested service for these older attics.
Cellulose Insulation
Signs you need it
You notice your second-story bedrooms run hot in summer while the air conditioning runs constantly, and your attic insulation looks thin, dusty, and compressed when you peek up there.
What it costs in Sherman Oaks
Cellulose insulation in Sherman Oaks typically runs $0.90 to $1.80 per square foot installed.
How we do it
We air-seal the attic floor, then blow GreenFiber cellulose to an even depth across the entire cavity, including hard-to-reach corners.
Blown In Attic Insulation
Signs you need it
Your energy bills climb every summer and the rooms directly under the attic never seem to catch up to the thermostat setting.

Blown in attic insulation in Sherman Oaks generally falls between $1,200 and $2,800 for a typical single-story home.
How we do it

Is blown in insulation worth it for an older Sherman Oaks home?
Yes, and in most cases it’s the most cost-effective single upgrade you can make. Older Sherman Oaks attics are under-insulated, and blown in material fills gaps and corners that batts never covered, so you feel the difference in the rooms directly below.

Homes built between the 1940s and 1960s benefit the most, because they typically have original R-11 insulation that’s now compressed flat. Second-story rooms that run hot in summer are the most common sign, and those attics almost always need both new insulation and air sealing.

What Sherman Oaks Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Jason Hoffman"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."
— Colleen Vaughn"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."
— Amanda Sullivan
