Insulation Company in Temple City, CA
Blown in insulation solves the most common comfort problem we see in Temple City: hot, stuffy rooms in a 1940s or 1950s bungalow with original walls that were never insulated. Homes here sit through long San Gabriel Valley summers where temperatures push past 95°F, and attics over low-pitch roofs trap heat that radiates into living space for hours after sunset. Fountain Valley Insulation has served Temple City since 2014, and we carry eight manufacturer brands so the material we install matches your house, not what’s left on the truck. Call (833) 390-3099 for a free estimate.
Why Temple City Homes Are Different
Temple City’s housing stock is mostly single-story wood-frame construction from the 1940s through the 1960s, with original plaster walls built without any wall insulation. That means the attic is doing nearly all the thermal work in these homes, and most of those attics are low-pitch, tight, and hold old insulation that has settled or been contaminated by rodents over the decades. On blocks near Las Tunas Drive and Live Oak Avenue, we regularly find original 1940s rock wool batts that have slumped against the eave vents and blocked attic airflow entirely. The fix is not just adding more material on top: the old stuff has to come out, baffles go in to restore ventilation, and then we blow in fresh cellulose or fiberglass at the correct depth for this climate zone.
The other Temple City factor is the lot pattern. Homes are packed tightly along narrow lots, so afternoon sun hits both east and west walls with little shade relief. Attic insulation and radiant barriers carry more weight here than in neighboring cities with newer tract housing, because the roof deck is the largest single heat gain surface. When Santa Ana winds kick up in the fall, they also drive dust and debris into attic vents, which is why we check vent screens and air-seal top plates as part of any blown in insulation job in the 91780 ZIP code.
Our Main Temple City Services
Most Temple City homeowners call us about two things: attic insulation that needs to be brought up to modern standards, and spray foam for difficult spots like cathedral ceilings, rim joists, and garage conversions. Here’s how each one works on this city’s housing stock.
Attic Insulation in Temple City
Temple City attics from the 1940s and 1950s are low-pitch and awkward to work in, which is exactly why the job starts with air-sealing and baffle installation before any new material goes down. We often remove old settled rock wool or pink fiberglass that has compacted to R-value levels well below what the original label promised. Once the attic floor is clean, we blow in cellulose or fiberglass to the correct depth and check that every eave vent is open. If your attic has old, dusty insulation or you feel heat radiating through the ceiling on summer evenings, the full picture is on the Attic Insulation in Temple City page.
Spray Foam Insulation in Temple City
Spray foam earns its cost in Temple City when a standard blown in material cannot reach the space: open attic ceilings, garage conversion projects, or addition roof decks where building code requires an air barrier. We install open-cell and closed-cell foam from Icynene and Demilec, two brands most general insulation contractors do not carry. On older Temple City bungalows, closed-cell foam also stiffens the roof assembly and helps seal gaps that dust and Santa Ana wind pressure exploit.

Blown In Insulation in Temple City
Blown in insulation is the workhorse solution for Temple City’s 1940s and 1950s bungalows because it fills irregular stud bays and attic floors that rigid batts cannot seal. Most of these homes were built with no wall insulation and attics that hold maybe three or four inches of settled, compressed material, which is why cooling bills spike every summer and bedrooms on the west side of the house never cool down. We remove what has failed, air-seal the top plates and penetration points, and blow in fresh material at the depth this inland climate demands. If you are deciding between materials, see what we cover on the Blown In Insulation page before you choose.
Cellulose Insulation
Signs you need it
Your attic currently holds old fiberglass batts that have settled to less than half their original thickness, or you can see the tops of the ceiling joists poking through the existing material.
What it costs in Temple City
Blown in cellulose in Temple City typically runs $1.15 to $2.30 per square foot installed, which for an average 1,200-square-foot attic lands between $1,380 and $2,760 before any old insulation removal.
How we do it
We remove or work around the failed material, air-seal the ceiling plane, install baffles at the eaves, then blow in cellulose to the R-value target for this climate zone and level it with a depth gauge.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic stay hot well past sunset in summer, or your energy bills climb every July and August while the rest of the house stays uncomfortable.
What it costs in Temple City
Blown in attic insulation here averages $1.15 to $2.30 per square foot, so a typical Temple City attic floor runs $1,380 to $2,760, while homes needing old-material removal first may see an added $1 to $2 per square foot for extraction and disposal.
How we do it
We inspect the attic deck for air leaks, seal around wiring and plumbing penetrations, install or repair baffles, blow the material to the correct depth, and verify the final R-value with a depth inspection.
Blown In Cellulose Insulation
Signs you need it
You want a denser, recycled-content option that performs well in attics and walls, especially if the existing material is old, dusty, or badly settled.
What it costs in Temple City
Expect $1.15 to $2.30 per square foot installed in Temple City, with the final number driven by attic access, ceiling height, and how much old material has to come out first.
How we do it
We run a hose from the truck to the attic or wall cavity, blow the cellulose at the manufacturer’s specified density, and inspect coverage with depth markers in multiple spots.
Blown In Fiberglass Insulation
Signs you need it
You prefer fiberglass for its moisture resistance or you are topping up an attic that already has clean fiberglass batts but not enough depth for this climate.
What it costs in Temple City
Blown in fiberglass runs $1.15 to $2.30 per square foot installed in Temple City, and if we need to remove settled material first, add $1 to $2 per square foot for that separate step.
How we do it
We use a high-volume blower to distribute fiberglass across the attic floor to the specified depth, then check density and coverage against the Department of Energy’s zone recommendations for the San Gabriel Valley.
What Blown In Insulation Costs in Temple City
| Item | Typical range in Temple City |
|---|---|
| Blown in insulation (attic or walls) | $1.15 – $2.30 per sq ft |
| Air sealing (top plates, penetrations, can lights) | $250 – $900 per attic |
| Old insulation removal | $1 – $2 per sq ft |
These numbers reflect what we quote across Temple City jobs, and every estimate is line-itemed before work starts. Taller attic spaces, excessive old material, and tight access all push price upward, but we do not surprise homeowners with change orders mid-job.
How much does blown in insulation cost for a Temple City bungalow?
For a typical 1,200-square-foot attic in Temple City, blown in insulation runs $1,380 to $2,760 before any removal or air-sealing work. Call (833) 390-3099 for an exact quote on your square footage.
Can blown in insulation be installed in Temple City homes with knob-and-tube wiring?
We do not blow insulation over active knob-and-tube wiring, and many 1940s Temple City homes still have it in attic spaces. We will identify it during the inspection and recommend the correct sequence with a licensed electrician before any insulation goes in.

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."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
