Insulation Company in Sherman Oaks, CA
Blown in insulation is the most common upgrade we install in Sherman Oaks, and for good reason: the San Fernando Valley’s summer heat pushes attic temperatures past 140°F by August, and most mid-century homes here were built with thin kraft-faced batts that lost their R-value decades ago. We’re Laguna Hills Insulation, and we’ve served Sherman Oaks since 2014. Call (866) 393-6041 and we’ll tell you honestly whether blown-in fiberglass, cellulose, or a different approach fits your attic.
Why Sherman Oaks Homes Are Different
Sherman Oaks sits in the hottest pocket of the San Fernando Valley, where summer highs run 10 to 15 degrees above nearby Studio City and the sun beats down on flat and low-slope roofs all afternoon. The housing stock tells the rest of the story. Much of Sherman Oaks was built out between the 1950s and 1970s: single-story ranch homes and two-story dingbat apartments with shallow attics, original insulation that’s compressed or settled, and ad hoc HVAC duct runs snaking through spaces never designed for modern cooling loads. Those old attics often have little clearance, so insulation work here frequently means air sealing penetrations and addressing ductwork before adding R-value. LADWP’s tiered summer rates make this a measurable bill-cutting move, not an efficiency nicety. The dominant load in Sherman Oaks is cooling, not heating, which shifts insulation priorities toward high R-value attic coverage, radiant barriers, and sealing the dense hot-air penetrations that let conditioned air escape into a 140-degree attic.
Our Main Sherman Oaks Services
Sherman Oaks homeowners call us most about two services: attic insulation for those hot, under-insulated mid-century attics, and spray foam for air sealing and thermal control in tight or awkward spaces.
Attic Insulation in Sherman Oaks
Attic insulation in Sherman Oaks starts with a real look at what’s already up there, because most 1950s and 1960s ranch homes have original batts that have settled to a fraction of their labeled R-value. We map your duct runs, check venting, and measure clearance before recommending a material. In many Sherman Oaks attics, the best result comes from air sealing first, then blowing insulation to a consistent depth. Attic Insulation in Sherman Oaks covers the full scope, from radiant barriers to high R-value blow-in over existing batts.
Spray Foam Insulation in Sherman Oaks
Spray foam in Sherman Oaks addresses a specific Valley problem: air leaks. When attic temperatures hit 140°F, the air in your attic is pushing through every penetration, and that’s where spray foam’s air-sealing performance matters. Closed-cell foam from Icynene or Demilec creates an air barrier and a thermal barrier in one pass, which works well in dingbat-style buildings with limited cavity depth. Spray Foam Insulation in Sherman Oaks explains the open-cell versus closed-cell decision for Sherman Oaks homes specifically.

Blown In Insulation in Sherman Oaks
Blown in insulation in Sherman Oaks is the fastest way to bring a 1950s or 1960s attic up to modern R-value, because loose fill settles into every corner and irregular joist bay that old batts left exposed. Sherman Oaks attics are often shallow and crisscrossed with duct runs, and blown-in fiberglass or cellulose flows around those obstructions better than any batt ever could. We install both, and the choice depends on your attic’s condition, your budget, and whether you want the recycled-content option from GreenFiber. Read more about Blown In Insulation or call (866) 393-6041 to talk through your attic.
Cellulose Insulation
Signs you need it
Your attic has settled or patchy old insulation, and you want a dense, recycled-content material that blocks airflow better than fiberglass.
What it costs in Sherman Oaks
In Sherman Oaks, GreenFiber cellulose blow-in runs about $1.50 to $3.50 per square foot installed, with dense-pack wall applications on the upper end.
How we do it
We air seal the attic floor penetrations first, then run a hose into the attic and blow cellulose to the target depth and R-value, working around existing duct runs and recessed lights.
Blown In Attic Insulation
Signs you need it
Rooms are consistently hot in summer despite the AC running, and your attic floor insulation measures below R-30 or sits uneven across joist bays.
What it costs in Sherman Oaks
Blown-in attic insulation in Sherman Oaks generally runs $1.50 to $4.00 per square foot installed, depending on target R-value, material, and whether old insulation needs removal first.
How we do it
We inspect the attic, air seal the major penetrations, then blow fiberglass or cellulose to a uniform depth that hits your target R-value, typically R-38 to R-49 for Valley homes.
Blown In Fiberglass Insulation
Signs you need it
You want a cost-effective, non-settling loose fill with a proven R-value per inch, and your attic has consistent joist spacing without major moisture issues.
What it costs in Sherman Oaks
Blown-in fiberglass in Sherman Oaks costs about $1.00 to $3.00 per square foot installed, with brand choice from Owens Corning or Johns Manville affecting the final number.
How we do it
We blow loose-fill fiberglass across the attic floor to a consistent depth, adding as much as R-49 where joist depth allows and using baffles to keep eave vents clear.

Is blown in insulation worth it in Sherman Oaks?
Yes, especially with LADWP’s tiered summer rates. Blown-in insulation cuts attic heat transfer, which lowers AC runtime and evens out room temps. Most Sherman Oaks homes see a noticeable change in comfort the first August after an upgrade.
Can you blow insulation over old batts in a Sherman Oaks attic?
Often, yes. If the old batts are dry and not compressed, we can blow loose fill over them to reach R-49. We check for moisture and seal penetrations first. Call (866) 393-6041 for an attic inspection and a straight answer.
