Insulation Company in Temple City, CA
Blown in insulation is the most common retrofit we install in Temple City, because most of the housing stock went up between the 1920s and 1950s, long before insulation was required by code. We’re Rock Solid Insulation, and we work on those older bungalows and early ranch homes regularly, including tight attics and plaster-walled rooms where original insulation is thin or missing entirely. If you’re dealing with high summer cooling bills or rooms that never hold a steady temperature, call us at (855) 798-0822 for a free estimate.
Why Temple City Homes Are Different
Temple City sits in the warm, semi-arid San Gabriel Valley, which means the insulation problem here isn’t about freeze protection. It’s about radiant heat gain through the roof. Long hot summers push attic temperatures well past 130 degrees, and that heat radiates down into living spaces for hours after sundown. In an older home with little or no attic insulation, the AC works against that heat load all day and much of the night. Insulating properly in Temple City is primarily about keeping summer heat out and cutting AC run time.
The housing stock makes that work specific. Much of Temple City is small-to-mid single-story wood-frame bungalows and early ranch homes from roughly the 1920s through the 1950s. Many have stucco exteriors, plaster interior walls, and original or minimally upgraded attic insulation. In those older bungalow blocks, plaster-and-lath walls often have little or no cavity insulation, and attics are commonly low-pitch, unvented, or poorly vented. Our crews regularly find original rock wool that has settled to a thin layer, or nothing at all. Knob-and-tube era wiring is also common, which requires careful planning before any insulation goes over or around it.
The physical layout of the city shapes the work too. Temple City’s lots are tight and narrow, and the residential grid is heavily built out. That means limited side-yard access, low-clearance attics, and fewer options for staging equipment. Jobs here aren’t like work in newer inland subdivisions with wide lots and tall attic trusses. They take more planning, more patience, and crews who know how to work in older, tighter homes without damaging plaster ceilings or disturbing old wiring.
Our Main Temple City Services
Two services account for most of the calls we get from Temple City homeowners: attic insulation and spray foam insulation. Each one fits a different set of problems in this housing stock.
Attic Insulation in Temple City
In Temple City’s older single-story bungalows and ranch homes, attic insulation is usually the single biggest lever for reducing summer cooling costs. Many of these homes still have a thin layer of settled fiberglass or original rock wool from decades ago. We blow in new material over the existing layer once we confirm the wiring is safe and the attic can handle the added depth. It’s faster and far less disruptive than tearing open walls, which matters a lot in plaster-and-lath homes. Read more about Attic Insulation in Temple City.

Spray Foam Insulation in Temple City
Spray foam makes sense in Temple City when a homeowner wants air sealing along with thermal insulation. Older wood-frame homes here leak air around top plates, can lights, and plumbing penetrations, and that leakage pulls hot attic air into the house. Closed-cell foam also adds structural rigidity, which is useful on some of the post-war tract infill homes with thinner roof decking. It’s a more involved install than blown-in, but for low-pitch attics and knee-wall areas it can be the best fit. Read more about Spray Foam Insulation in Temple City.

Blown In Insulation in Temple City
Blown in insulation in Temple City is most often a retrofit job on homes built between the 1920s and the 1950s, when insulation was rarely code-required and many attics were left with just a thin layer of whatever was cheap at the time. The semi-arid valley climate turns that missing insulation into a summer-long AC burden, because attic heat radiates through the ceiling for hours every afternoon and evening. We install Blown In Insulation using cellulose and fiberglass systems matched to the specific attic conditions in Temple City’s older wood-frame and stucco homes.
Cellulose Insulation
Signs you need it
Your attic has settled insulation from decades past, or rooms directly under the attic get noticeably hotter than the rest of the house by mid-afternoon.
What it costs in Temple City
Blown in cellulose insulation in Temple City typically runs $1.25 to $2.10 per square foot for R-38 to R-49 coverage, including labor and material.
How we do it
We run a fill hose into the attic from a truck-mounted machine, blow GreenFiber cellulose to the specified depth, and level it across the attic floor while keeping soffit vents clear.
Blown In Attic Insulation
Signs you need it
Your attic floor has bare patches, rock wool that’s compressed to less than a couple inches, or you can see the ceiling joists clearly.
What it costs in Temple City
Blown in attic insulation for a typical Temple City bungalow attic usually lands between $1,800 and $3,400 depending on square footage and target R-value.
How we do it
We inspect the attic for wiring and venting issues, seal any major bypasses, then blow in loose fill to the depth required for the R-value the home needs.
Blown In Fiberglass Insulation
Signs you need it
You want an insulation that won’t settle over time and prefer a material that’s less dusty than cellulose during install.
What it costs in Temple City
Blown in fiberglass insulation in Temple City generally runs $1.50 to $2.60 per square foot for R-38 to R-49 attic coverage.
How we do it
We use Owens Corning or Johns Manville loose fill fiberglass, blown to depth with the same truck-mounted equipment, with extra care taken around recessed lights and vent baffles.

Is blown in insulation worth it in Temple City’s climate?
Yes. The summer heat gain through an uninsulated or under-insulated attic is the biggest driver of high AC bills in Temple City. Blown in insulation cuts that heat transfer measurably, and most homeowners notice the difference the first summer after install. Call (855) 798-0822 for a specific quote on your attic.
Can you blow insulation into existing walls in Temple City?
Yes, in many cases we can. Plaster-and-lath walls on older Temple City bungalows can be dense-packed with cellulose through small drilled holes, then patched. It’s more invasive than attic work but far less than gutting walls. Call us at (855) 798-0822 so we can assess your wall cavities.
Brands We Service in Temple City
We install GreenFiber cellulose, Owens Corning and Johns Manville fiberglass, and Knauf batts across Temple City, depending on the application. We keep the most common loose fill materials stocked locally for quick turnaround on attic retrofits, which means most Temple City jobs don’t wait on material delivery. See our brands for the full range.

— Dev Patel"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Sami Mansour"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."
