Insulation Company in Temecula, CA
Blown in insulation solves the single biggest comfort problem in Temecula: heat pouring down from a 150°F attic into living spaces below. Most homes here were built between 1985 and 2005 with builder-grade fiberglass batts and flex duct that have since settled, compressed, or fallen out of place. We’re Orange County Insulation, an insulation-only contractor that has served Temecula since 2013, and we replace tired attic insulation with the right blown-in material for this specific climate.

Why Temecula Homes Are Different
Temecula sits in a wind-swept, semi-arid inland valley where summer afternoons regularly pass 100°F and Santa Ana winds rake the western hillsides. Insulation here is not the same job you’d do in a coastal or mountain market. The real problem is radiant heat from those concrete tile roofs and hot attic air leaking through every crack in the ceiling plane, not winter cold. Builders in the 1980s and 1990s stuffed attics with R-19 or R-30 fiberglass batts, which is marginal at best for this climate and often installed poorly around trusses and can lights. Add in flex duct that sags across oven-hot attics, and you get the classic Temecula complaint: a hot upstairs that never cools down no matter how hard the AC runs.
The housing stock itself matters too. Redhawk, Paloma del Sol, Wolf Creek, and Vintage Hills are mostly stucco-on-wood-frame, two-story homes with concrete tile or composite roofs. Those tile roofs make attic access slower and more deliberate than shingle work, and they hold heat late into the evening. When we work in Temecula, we approach every job as a radiant-heat and air-sealing project first, and an R-value upgrade second. That’s the difference between patching a symptom and fixing the actual problem.
Our Main Temecula Services
Temecula homeowners call us most about two things: re-insulating attics that were under-insulated from day one, and upgrading to spray foam where traditional insulation keeps falling short. Here’s what each involves locally.
Attic Insulation in Temecula
Most Temecula attics we see still have the original fiberglass batts from the 1990s or early 2000s. Those batts have likely compressed to half their rated R-value, and in many cases the flex duct running through the attic has separated at the joints. We remove the old material, seal plumbing and electrical penetrations, and blow in fresh insulation matched to the roof type and attic configuration. Tile roofs add a layer of care to the job, since we’re working in tight clearances and often around recessed lighting that needs baffle protection. Read the full breakdown on our dedicated Attic Insulation in Temecula page.
Spray Foam Insulation in Temecula
Spray foam is the strongest answer for Temecula’s radiant heat problem because it seals air leaks while it insulates. Closed-cell foam performs especially well under tile roofs where attic temperatures stay high, and open-cell foam works for quieter interior walls and sound control between floors. We install both, backed by Icynene and Demilec product lines, so the recommendation is based on what your attic actually needs rather than what we have on the truck. Details are on our Spray Foam Insulation in Temecula page.

Blown In Insulation in Temecula
Blown in insulation is the most practical re-insulation method for Temecula’s 1980s-to-2000s tract homes, where old batts have settled and gaps have opened around ceiling fixtures. Loose-fill fiberglass or cellulose fills the irregular cavities in a way batts never can, and it lets us bring an under-insulated attic up to current standards without tearing out drywall. For most Temecula attics, we blow a deep layer across the entire attic floor, working around the tile-roof access constraints and sealing bypasses first. Learn more about the method on our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
You feel heat radiating from the ceiling on summer afternoons, or your upstairs rooms run 8 to 12 degrees hotter than downstairs.
What it costs in Temecula
Cellulose blown into an existing attic in Temecula typically runs $1.60 to $2.60 per square foot depending on depth and access.
How we do it
We seal air leaks at the ceiling plane, then dense-pack or loose-fill GreenFiber cellulose to the target R-value for our climate zone.
Blown In Attic Insulation
Signs you need it
Your energy bills climb every summer while the AC runs nonstop, and the attic insulation looks thin, patchy, or matted down.
What it costs in Temecula
Blown in attic insulation for a typical 1,800-square-foot Temecula home lands between $3,800 and $6,200 for full removal, air sealing, and new material.
How we do it
We remove the old material, air-seal penetrations, and blow fresh insulation to an even depth across the attic floor.
Blown In Cellulose Insulation
Signs you need it
You want a recycled-content option that also slows airflow better than fiberglass, especially on windy Santa Ana days.
What it costs in Temecula
For a standard attic floor, blown cellulose runs $1.60 to $2.60 per square foot installed in the 92590 through 92593 ZIP codes.
How we do it
We shoot GreenFiber cellulose through a calibrated hose to a consistent depth, then fluff and level it with rakes before we leave.
Blown In Fiberglass Insulation
Signs you need it
You want a lighter-weight material that won’t settle as much as cellulose over time, especially in deeper attic cavities.
What it costs in Temecula
Blown fiberglass runs $0.90 to $1.50 per square foot installed, making it a solid value for large attic floors in newer subdivisions.
How we do it
We blow Owens Corning or Johns Manville loose-fill fiberglass to the specified depth, covering the full attic floor in one pass.
Loose Fill Insulation
Signs you need it
Your attic has awkward framing, low clearances, or lots of can lights that make batt installation impractical.
What it costs in Temecula
Loose fill insulation is the same material and pricing as blown-in: $0.90 to $2.60 per square foot based on fiberglass vs. cellulose.
How we do it
We use a blower machine to fill every cavity evenly, working around tile-roof trusses and keeping vents clear as we go.
What Blown In Insulation Costs in Temecula

|---|---|
| Blown fiberglass (attic floor) | $0.90 – $1.50 per sq ft |

Does blown in insulation make a big difference in Temecula heat?
Yes. A deep layer of blown insulation across the attic floor blocks radiant heat from entering living spaces, which is the main driver of hot upstairs rooms in Temecula. Even upgrading from compressed R-30 to a fresh R-49 layer changes how long the AC runs. Call (877) 680-3557 for an exact quote.
Can you do blown in insulation in one day in Temecula?
Most standard attic re-insulation jobs finish in a single day, including old material removal and air sealing. Tile-roof attics can add time because of access. We’ll give you a clear timeline before we start the work.

What Temecula Customers Say
"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Beatriz Vargas"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Miguel Flores"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."
