Insulation Company in Temple City, CA
Blown in insulation is the workhorse retrofit for Temple City’s older homes, and it’s what we install most often here. Most houses in this San Gabriel Valley city went up between the 1920s and 1950s, which means attics with settled rock wool, compacted vermiculite, or nothing at all above the ceiling. Summer afternoons in the 90s and 100s turn those attics into heat chambers, and under-insulated ceilings push that heat straight into living spaces. Fontana Insulation has served Temple City since 2011, and we carry eight insulation brands so the material we blow in matches your attic’s actual conditions, not whatever we happen to have on the truck.

Why Temple City Homes Are Different
Temple City is a built-out San Gabriel Valley city where insulation work is overwhelmingly retrofit-and-upgrade rather than new construction, and the attic is the battlefield. Lots are tight, and many homes are single-story with low-pitch hip roofs that leave shallow, hard-to-access attic triangles. Crews here routinely find original 1940s and 50s rock wool or vermiculite that has compacted to a few inches, mixed with old knob-and-tube or early Romex-era wiring. That combination means every blow-in job starts with a careful inspection and air-sealing pass before any new insulation goes down. You cannot blow-and-go in Temple City, and we don’t try.
The local climate shapes the work too. Inland San Gabriel Valley heat makes attic radiant heat and under-insulated ceilings the dominant comfort and energy problem. Mild winters mean cooling-season performance matters far more than heating. For most Temple City homeowners in the 91780 ZIP, the goal is stopping heat gain from above, tightening the thermal boundary, and keeping conditioned air from leaking into a 120-degree attic. The wiring awareness piece is specific to this area: older Romex and knob-and-tube circuits buried under old insulation create both safety and code considerations that newer tract housing in other cities simply doesn’t have.
Our Main Temple City Services
Most Temple City homeowners call us about two problems: attics that bake the house all summer, and air leaks that make the air conditioner work harder than it should. Both services are specific to the older housing stock here.
Attic Insulation in Temple City
Attic insulation in Temple City means working inside shallow, low-pitch hip roof cavities where original insulation has settled or vanished. We remove what’s there, inspect the wiring and top plates, air-seal the penetrations, then install material matched to the attic’s depth and venting. On a typical 1940s bungalow, that sequence takes one day. For a full breakdown of options and costs for Attic Insulation in Temple City, that page covers the details for your home’s era and roof style.
Spray Foam Insulation in Temple City
Spray foam is the right call for Temple City homes where air sealing matters as much as R-value, like attics with old can lights, open wall cavities in additions, or crawlspaces that pull hot air into the house. We install Icynene and Demilec open- and closed-cell foam, and we’re authorized installers for both. Closed-cell works well in tight Temple City attics where space for depth is limited.

Blown In Insulation in Temple City
Blown in insulation in Temple City is the most common retrofit we install, because it’s the most practical way to re-insulate an old attic without tearing out ceilings. The typical job here is a 1920s-to-1950s bungalow or ranch where the original rock wool or vermiculite has compacted to a few inches or blown away entirely, leaving the ceiling as the only thermal barrier against summer attic heat that routinely exceeds 120 degrees. Blown in fiberglass or cellulose fills the joist bays evenly, gets under low-pitch hip roof framing that batts can’t reach, and can be installed over properly inspected older wiring in a single day. For homeowners comparing material types, our Blown In Insulation hub page explains the full lineup we stock.
Cellulose Insulation
Signs you need it
Your attic has settled insulation under four inches deep, or you feel heat radiating through ceilings on summer afternoons and notice the air conditioner running nonstop during peak hours.
What it costs in Temple City
Cellulose blow-in for a typical Temple City attic runs $1.80 to $3.20 per square foot depending on depth needed and access difficulty.
How we do it
We remove the old compacted material, inspect the wiring and top plates, air-seal penetrations and bypasses, then blow GreenFiber cellulose to the depth that hits your target R-value.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic feel 10 to 15 degrees warmer than the rest of the house, or you can see bare joist tops and thin, patchy insulation when you peek into the hatch.
What it costs in Temple City
Blown in fiberglass attic insulation in Temple City typically ranges from $1.50 to $3.00 per square foot for full removal and re-blow on a single-story home.
How we do it
We remove the old material, air-seal every penetration and top plate, install baffles where venting needs protection, then blow Knauf or CertainTeed fiberglass to the specified R-value with a depth marker check.
Blown In Cellulose Insulation
Signs you need it
You want the higher recycled content and sound dampening that cellulose provides, and your attic has wiring that’s been inspected and confirmed safe for dense coverage.
What it costs in Temple City
Blown in cellulose in Temple City runs $1.80 to $3.40 per square foot including removal of old material, air sealing, and the finished R-value.
How we do it
We remove what’s settled or contaminated, verify the junction box and wire conditions, seal bypasses, then blow GreenFiber cellulose through a hose to an even depth that meets the R-value we specified for your attic.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old fiberglass batts that have flattened or shifted, leaving gaps at the eaves and around framing, and you want a material that won’t settle or hold moisture.
What it costs in Temple City
Blown in fiberglass for Temple City attics typically costs $1.50 to $3.20 per square foot depending on whether we’re topping off existing material or doing full removal and re-blow.
How we do it
We clear the work area, air-seal the attic floor, then use a calibrated blowing machine to install Knauf or CertainTeed fiberglass at the density that achieves the R-value without compressing the material.
Loose Fill Insulation
Signs you need it
You have awkward attic geometry, low-pitch hip framing, or lots of cross-bracing and recessed light housings that make batt installation impractical, and the current loose fill has settled flat.
What it costs in Temple City
Loose fill insulation installs in Temple City generally run $1.50 to $3.40 per square foot including removal, prep, air sealing, and the new blown material.
How we do it
We remove old material down to the attic floor, inspect the electrical, seal all penetrations, then blow loose fill fiberglass or cellulose into every bay until the depth gauge confirms the specified R-value.

Can you install blown in insulation over old knob-and-tube wiring?
No. Insulation should never cover active knob-and-tube wiring because it creates a fire hazard by trapping heat. In Temple City, we inspect the attic wiring before any blow-in job and work with a licensed electrician to address unsafe circuits first. Call (866) 271-1602 for an attic assessment.
How long does a blown in insulation job take in Temple City?
Most Temple City attics are done in one day, including removal of old material, air sealing, and the re-blow. Larger or steeper attics with wiring issues may take a second day. Call (866) 271-1602 to schedule a same-week estimate.
Brands We Service in Temple City

See our full our brands lineup for what we stock and why each earns a place on the truck. Most materials are available same week for Temple City installs.

What Temple City Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"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."
— Sarah Fletcher"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."
— Holly Mercer
