Insulation Company in Sherman Oaks, CA
Blown in insulation is the workhorse retrofit for Sherman Oaks homes, and it’s where most of our calls start. The 1940s through 1970s Valley ranches that fill these streets were built with thin, settled fiberglass or nothing at all in the attic, and in a climate where attic temperatures push past 150°F in August, that translates directly into brutal cooling bills. Our team installs loose fill and blown in cellulose and fiberglass with air sealing done right, because adding R-value over a leaky ceiling is wasted money. Call us at (866) 566-0304 and we’ll tell you what your attic actually needs.
Why Sherman Oaks Homes Are Different
Sherman Oaks sits in the hottest inland pocket of the San Fernando Valley, where summer highs routinely run 15 to 25 degrees above coastal Los Angeles. That changes the entire insulation conversation. This isn’t about keeping the cold out like it is in older coastal LA homes. It’s about heat rejection, radiant barriers, and high R-value attic work aimed squarely at cutting AC load. The housing stock makes it specific too: mostly single story ranch and traditional homes from the 1940s through the 1970s with low pitch attics and stucco exteriors, plus newer multi story infill along the hillsides and Ventura Blvd corridors. The older homes almost always have thin original attic insulation, aging ductwork, and vented attics that need air sealing before anything else. Down in the flats north of Ventura Blvd, attics are low and easy. Up the hilly south side streets near the Santa Monica Mountains foothills, we regularly work in steep sloped ceilings and tight attic knees where blow in equipment has to navigate clearances that flat lot tract homes never demand.
The dry climate and Santa Ana wind events also mean fire resistant assemblies and properly vented attics matter. That’s not a general concern everywhere in Los Angeles, but in Sherman Oaks it’s part of doing the job correctly.
Our Main Sherman Oaks Services
The two services Sherman Oaks homeowners call about most are attic insulation and spray foam, and each one handles a different set of problems depending on your house and where the heat is coming from.
Attic Insulation in Sherman Oaks
Most Sherman Oaks homes built before 1980 have attics with settled, compressed fiberglass or loose fill that’s nowhere near current R-value recommendations for the Valley. That’s the first place we look, because a properly done attic upgrade with air sealing and high R-value coverage addresses the single largest source of residential heat gain. For homes in the flats, the work is straightforward. For hillside homes with low clearance and sloped ceilings, it takes a crew that’s done it before. Attic Insulation in Sherman Oaks covers what we do in these attics and what it costs to bring them up to standard.
Spray Foam Insulation in Sherman Oaks
Spray foam makes sense for Sherman Oaks homeowners dealing with hard to reach attic knees, rim joists, and the sloped ceiling assemblies common on the south side of the boulevard. Closed cell foam air seals and insulates in one pass, which matters when you’re fighting triple digit heat and want to stop conditioned air from leaking out. We install both open and closed cell products from Icynene and Demilec, and we help you decide which one fits your specific attic or wall assembly. Spray Foam Insulation in Sherman Oaks explains the difference and walks through pricing for typical Sherman Oaks applications.
Blown In Insulation in Sherman Oaks
Blown in insulation is the fastest, most thorough way to bring an older Sherman Oaks attic up to current standards without tearing the house apart. Loose fill cellulose or fiberglass gets blown into every corner, around every truss, and over existing insulation that’s settled or thinned out over decades of Valley heat. The problem we solve here is specific: homes built between the 1940s and 1970s rarely have enough attic insulation for a climate where summer temps stay in the triple digits for weeks at a time, and loose fill is the practical retrofit answer for those low pitch, hard to reach attics. We recommend blown in work for most Sherman Oaks attics because it fills irregular cavities better than batts ever will, especially in the tight, low clearance spaces you find on hillside streets south of Ventura Blvd. You can read more about the method itself on our Blown In Insulation hub, but here’s what it looks like in Sherman Oaks specifically.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to the point where joists are visible and you can feel heat radiating through the ceiling by mid afternoon.
What it costs in Sherman Oaks
Blown in cellulose for a typical Sherman Oaks attic runs $1,200 to $2,800 depending on square footage and the R-value you’re targeting.
How we do it
We air seal all ceiling penetrations first, then blow dense packed or loose fill cellulose to the specified depth using GreenFiber recycled content material when you want a low VOC option.
Blown In Fiberglass Insulation
Signs you need it
You have patchy or uneven attic coverage, or you’re topping off old fiberglass batts that no longer meet current R-value for Valley heat.
What it costs in Sherman Oaks
Blown in fiberglass for a standard Sherman Oaks attic ranges $1,000 to $2,500 depending on depth and whether air sealing is included.
How we do it
We run a hose from the truck up through your access point and blow loose fill fiberglass across the full attic floor, working around obstacles and keeping baffles clear at the eaves.
What Blown In Insulation Costs in Sherman Oaks
| Item | Typical range in Sherman Oaks |
|---|---|
| Blown in cellulose (attic, R-38) | $1,200 – $2,800 |
| Blown in fiberglass (attic, R-38) | $1,000 – $2,500 |
| Air sealing before blow in | $400 – $900 |
Add air sealing to your blow in job and you’ll get far more out of every dollar of R-value. We quote it as a line item so you see exactly what you’re paying for.
How long does blown in insulation last in Sherman Oaks heat?
Loose fill cellulose and fiberglass both hold up well in Valley heat, but cellulose can settle 10 to 20 percent in the first few years and may need a top off. Fiberglass settles less. Expect 20 plus years of useful life if the attic stays dry.
Can you blow insulation over old insulation in Sherman Oaks?
Yes, as long as the existing material is dry and not moldy or pest damaged. We inspect first, then blow new loose fill directly over it to reach your target R-value. Call (866) 566-0304 for an attic inspection and quote.

What Sherman Oaks Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
- Diego Castillo"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."
- Gilbert Herrera"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."
