Insulation Company in Temecula, CA
Blown in insulation is the most common insulation upgrade we install in Temecula, and for good reason. The city’s 1990s and 2000s Mediterranean-style tract homes were built with insulation levels that simply cannot handle an inland valley where summer highs routinely pass 100°F. Hollywood Insulation Co has served Temecula since 2018, and our focus on insulation means we understand exactly what happens inside a tile-roof attic when the sun beats down all afternoon. Call (866) 605-6949 for a free estimate on blown in insulation or any of our other Temecula services.
Why Temecula Homes Are Different
Temecula’s climate is the defining factor in almost every insulation decision here. The city sits in a hot inland valley, and the intense sun on concrete tile roofs drives attic temperatures far above ambient air temperature. We regularly measure attic temperatures of 130°F to 150°F in Temecula during July and August, even when the outside temperature is 105°F. That heat load transfers directly into living spaces, forcing air conditioners to run longer and pushing cooling bills up.
The housing stock adds another layer of complexity. Most homes in the 92591 and 92592 ZIP codes are 1990s to 2000s Mediterranean or Spanish-style tract homes with ventilated attics and concrete tile roofs. The original insulation in these homes was typically R-19 fiberglass batts, which is inadequate for Temecula’s heat. Over time, that insulation has often compressed, been disturbed by HVAC retrofits, or simply settled. On the east side of town, larger custom homes on half-acre lots present different challenges, with complex rooflines and cathedral ceilings that require a more tailored approach. Tile roofs also mean we have to be careful with attic access, because broken tiles turn an insulation job into a roofing repair.
For homes in the 92592 ZIP with south- or west-facing roofs, the situation is even more pronounced. Those attics absorb sun all day, and we frequently find that the original insulation has degraded to the point where it is doing very little. Adding blown in insulation and a radiant barrier is one of the most effective upgrades a Temecula homeowner can make.
Our Main Temecula Services
Temecula homeowners call us most often about two things: attic insulation that needs to be brought up to current standards, and spray foam for air sealing and maximum R-value per inch. Here is what each service looks like in Temecula.
Attic Insulation in Temecula
Attic insulation in Temecula typically means adding blown in insulation on top of existing batts or starting fresh if the original material has compressed or been contaminated. With tile roofs and ventilated attics being the norm here, we focus on getting the attic to R-38 or better while keeping airflow working correctly. On homes in 92592 where attic temperatures run highest, we often pair insulation with a radiant barrier to reflect heat before it gets absorbed. Attic Insulation in Temecula covers the full scope of this work.
Spray Foam Insulation in Temecula
Spray foam is the strongest option for Temecula homes with bonus rooms, knee walls, or vaulted ceilings where traditional batts do not fit well. Closed-cell foam adds structural strength and blocks moisture, while open-cell foam air-seals and insulates in one pass. Because Temecula attics get so hot, we often recommend spray foam for walls and rooflines where traditional methods leave gaps. Spray Foam Insulation in Temecula explains the difference between Icynene open-cell and Demilec closed-cell systems.

Blown In Insulation in Temecula
Blown in insulation is the workhorse of Temecula insulation upgrades. Most homes in the 92591 and 92592 ZIP codes were built with R-19 fiberglass batts, and after 20 to 30 years of summer heat, that material has compressed and lost much of its effectiveness. Blown in fiberglass or cellulose can be installed quickly over existing insulation to bring attics up to R-38 or higher, which is what Temecula’s climate actually demands. The intense heat here means an under-insulated attic is not a minor comfort issue; it is the single biggest driver of summer cooling costs. Our blown in insulation service is detailed on the Blown In Insulation page.
Cellulose Insulation
Signs you need it
You need cellulose insulation if your attic insulation has settled below the top of the joists or you want a greener option with high recycled content.
What it costs in Temecula
Blown in insulation in Temecula typically runs from $1,500 to $3,200 depending on attic size and depth.
How we do it
We air-seal the attic floor first, then blow GreenFiber cellulose to the specified depth with a calibrated machine.
Blown In Attic Insulation
Signs you need it
You need blown in attic insulation if rooms directly under the attic feel 10 to 15 degrees warmer in summer or your AC runs almost continuously on hot afternoons.
What it costs in Temecula
Blown in attic insulation in Temecula is the same scope as general blown in work, typically $1,500 to $3,200.
How we do it
We inspect the existing insulation, calculate the additional depth needed to reach R-38, and blow the material evenly across the attic floor.
Blown In Fiberglass Insulation
Signs you need it
You need blown in fiberglass if you want a mold-resistant, non-settling insulation option at a lower material cost than cellulose.
What it costs in Temecula
Blown in fiberglass in Temecula runs in the same $1,500 to $3,200 range as cellulose, with fiberglass typically costing slightly less per bag.
How we do it
We use specific fiberglass blowing machines that fluff the material properly, achieving full R-value without the settling that hand-scattering causes.
What Blown In Insulation Costs in Temecula
| Item | Typical range in Temecula |
|---|---|
| Blown in insulation (attic to R-38) | $1,500 – $3,200 |
| Air sealing before blown in | $300 – $900 |
| Radiant barrier addition | $1,200 – $2,800 |
Is blown in insulation worth it for a Temecula home?
Yes. With summer attic temperatures regularly hitting 140°F or more, increasing attic insulation from R-19 to R-38 typically cuts cooling costs noticeably. Call (866) 605-6949 for a calculation specific to your home.
How long does blown in insulation last in Temecula?
Fiberglass blown in insulation lasts decades, while cellulose may settle slightly over the first year. In Temecula’s dry climate, neither material degrades quickly, and both outperform the original batts most homes were built with.

FAQs About Insulation Company in Temecula
For most blown in insulation jobs, we can be on-site within 3 to 5 business days of the estimate. Emergency air-sealing or pre-listing insulation work can sometimes be scheduled faster. Call (866) 605-6949 to check current scheduling.
Most attic insulation retrofits in Temecula do not require a city permit, especially when no structural changes are involved. Spray foam applications on rooflines may trigger a permit depending on scope, and we handle that determination during the estimate.
Interior and attic insulation work is almost never restricted by HOA rules in Temecula’s master-planned communities, since it is not visible from the street. If your HOA requires work-hour notice, we can coordinate our schedule around that.

What Temecula Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong
