Insulation Company in Sherman Oaks, CA
Blown in insulation is the most common call we handle in Sherman Oaks, and for a specific reason: the 1950s and 1960s ranch homes south of Ventura Boulevard and up into the hillside tracts were built when energy was cheap and insulation was an afterthought. Attics with a thin scatter of original rock wool, or none at all, are the norm here, not the exception. We match the material to your home, not the other way around. Whether that means blown-in cellulose in a tight hillside attic or fiberglass over a flat-roofed ranch, we carry the right system and install it correctly. Call (877) 265-5712 for a free estimate.
Why Sherman Oaks Homes Are Different
Sherman Oaks sits in the San Fernando Valley’s hottest inland pocket. Summer attic temperatures routinely climb past 150°F, which is a different world from the Westside’s coastal haze a few miles south. That heat load is why blown-in insulation work here is dominated by retrofits on mid-century ranch homes rather than the mild-climate batts you’d spec in Santa Monica. The tract housing built south of the Boulevard in the 1950s and 1960s went up with minimal or no attic insulation, and decades of added ceiling fans and recessed lights have done nothing to fix it. Our techs regularly find original 1960s rock wool compressed to the thickness of a bath mat, or bare drywall over the rafters.
Hillside homes off the ridge roads add another layer: tight, low-clearance attics and cantilevered sections where loose-fill is the only practical option. Blown-in material flows around framing and settles into odd cavities that batts simply can’t reach. And the foothill wildfire zones push demand toward fire-resistant assemblies: Rockwool mineral wool, which is non-combustible, has become a serious consideration for homeowners in the Santa Monica Mountains edge of the 91423 and 91495 ZIP codes. Mild winters still warrant proper R-values too; valley nights drop enough that a poorly insulated attic shows up on the gas bill.
Our Main Sherman Oaks Services
Most Sherman Oaks homeowners reach out about two things: the attic above their head and the air leaking through it. Here’s what each involves locally.
Attic Insulation in Sherman Oaks
Attic work in Sherman Oaks usually means pulling out whatever minimal material is up there and starting fresh. Homes built in the 1950s and 1960s south of the Boulevard often have no insulation at all, or a few inches of degraded fiberglass. We assess the existing depth, check for air leaks around recessed lights and plumbing penetrations, and build up to the R-value the valley climate actually demands. Flat and low-pitch roofs are common here, which changes venting strategy compared to steep-pitched builds. Attic Insulation in Sherman Oaks is our most-requested page for a reason. Call us for a free estimate.
Spray Foam Insulation in Sherman Oaks
Spray foam earns its keep in Sherman Oaks when homeowners want air sealing and insulation in one step. Open-cell Icynene works well in the low-clearance hillside attics where fiberglass batts are awkward to fit, while closed-cell Demilec adds structural rigidity and moisture resistance to post-and-beam builds in the foothills. The air-sealing benefit matters here because valley heat drives conditioned air out through every gap in the ceiling plane. Spray Foam Insulation in Sherman Oaks covers the options and what to expect. We’ll walk you through open-cell versus closed-cell and which fits your roof assembly.

Blown In Insulation in Sherman Oaks
Blown in insulation is the workhorse solution for Sherman Oaks because it’s the only practical way to retrofit a 1960s low-clearance attic without tearing the ceiling apart. Loose-fill material flows around framing, settles into the odd cavities left by decades of remodel work, and builds R-value quickly. In the valley’s 150°F summer attic heat, the difference between R-11 and R-38 is the difference between an upstairs that’s tolerable and one that isn’t. Blown In Insulation is our core service because it handles the housing stock here better than any other method. We carry GreenFiber recycled cellulose, which settles into a dense, effective layer, and blown fiberglass for homeowners who prefer it.

What Sherman Oaks Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nathan Padgett"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Gabriela Herrera"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
