Insulation Company in Valley Glen, CA
Blown in insulation is the most common retrofit we install in Valley Glen, and for good reason: the neighborhood’s 1950s and 60s ranch homes were built when energy was cheap and Valley summers weren’t as punishing. Today those same attics hit 150°F by August, and the original fiberglass batts have settled into near-uselessness. Placentia Insulation has served Valley Glen since 2018, matching the right material – GreenFiber cellulose, fiberglass, or mineral wool – to each home’s actual thermal gaps rather than blowing in whatever’s on hand.

Why Valley Glen Homes Are Different
Valley Glen sits in the heart of the San Fernando Valley, where summer temperatures routinely cross 100°F and the sun punishes roofs from June through October. The housing stock is overwhelmingly mid-century tract construction: single-story ranches thrown up fast during the postwar boom, insulated with thin fiberglass batts that met 1960 code but fall far short of what a 110°F summer demands. We walk into Valley Glen attics every week and find the same story: batts compressed to half their original depth, gaps around can lights and plumbing chases, and zero air sealing anywhere.
Homes near the Tujunga Wash side of Valley Glen have it worst. With less tree canopy than Sherman Oaks or Encino, those attics bake harder, and older blown-in cellulose settles faster under the relentless heat. Re-insulating here isn’t about keeping heat in. It’s about keeping heat out: radiant barriers, deeper cellulose, and air sealing that stops the attic from superheating the living space below. Valley Glen’s patchwork of original construction and room additions also means most homes have inconsistent thermal performance from one end of the house to the other – a problem blown in insulation is uniquely suited to fix, since it fills irregular cavities without tearing out drywall.
Our Main Valley Glen Services
Most Valley Glen homeowners call us about two things: re-insulating attics that have baked for 60 years, and sealing building envelopes with spray foam. Here’s what each involves locally.
Attic Insulation in Valley Glen
Attic work in Valley Glen almost always starts with the same discovery: the original batt insulation has settled, compressed, or been shoved aside during decades of electrical and HVAC work. We remove or supplement what’s there, seal air leaks, and blow in fresh material to a true R-value that matches the Valley’s heat load. Homes near the Tujunga Wash often need deeper coverage because the attic temperature swings harder without tree shade. Attic Insulation in Valley Glen covers the details, but the short version is: we fix the attic first, because that’s where Valley Glen homes lose most of their comfort.
Spray Foam Insulation in Valley Glen
Spray foam is the strongest answer for Valley Glen room additions, garage conversions, and the rim joists and knee walls that leak unconditioned air into living space. Because many Valley Glen homes have been added onto without upgrading the original envelope, the seams between old and new construction create thermal bypasses that batts can’t address. We carry both Icynene open-cell and Demilec closed-cell foam, so the material matches the application – open-cell for interior air sealing and sound dampening, closed-cell where moisture or structural rigidity matters. Spray Foam Insulation in Valley Glen explains when foam beats blown-in material.

Blown In Insulation in Valley Glen
Blown in insulation is the workhorse retrofit for Valley Glen’s mid-century tract homes. When we blow GreenFiber cellulose or fiberglass into a 1950s attic, we’re restoring the thermal buffer that the original builder never really provided – and that 60 years of Valley heat has degraded further. In most Valley Glen attics we inspect, the existing insulation has settled to R-19 or less, when a properly insulated attic for this climate should be closer to R-38 or R-49. Blown in material fills every void, covers the settled batts, and creates a continuous thermal blanket that batts can’t achieve. You can read more about the method on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Rooms that stay hot in summer despite the AC running, or attic insulation that’s visibly settled to below the joist tops, both point to cellulose being the right call.
What it costs in Valley Glen
Cellulose attic blow-in for an average Valley Glen ranch typically runs $1,800 to $3,200, depending on depth and any removal needed.
How we do it
We air-seal penetrations first, then blow GreenFiber cellulose to the target depth and density, checking R-value with a calibrated gauge before we leave.
Blown In Attic Insulation
Signs you need it
If your attic floor shows bare spots, thin coverage, or batts that have turned dark and powdery, the insulation has failed and needs a blown-in upgrade.
What it costs in Valley Glen
Blown in attic insulation in Valley Glen runs $1,500 to $2,800 for a typical single-story home, with dense-pack wall work adding to the total.
How we do it
We map the attic, air-seal recessed lights and chases, then blow fiberglass or cellulose to a consistent R-38 or R-49 across the entire floor.

How much does blown in insulation cost in Valley Glen?
Most Valley Glen homes fall between $1,500 and $3,200 for a full attic blow-in, depending on square footage, existing insulation condition, and whether removal is required. Call (855) 773-6429 for an exact quote – estimates are free.
Can blown in insulation be installed in Valley Glen homes without tearing out drywall?
Yes. Blown in material is installed through small access points or directly into the attic, making it the least invasive way to re-insulate Valley Glen’s older homes. Dense-packing walls requires drilling small holes that are patched afterward.

What Valley Glen Customers Say
"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Gilbert Ramirez"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."
— Veronica Guzman"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."
