Insulation Company in Highgrove, CA
Blown in insulation is the most requested service we handle in Highgrove, and for good reason: most homes here were built between the 1950s and 1980s with thin original attic insulation that was never designed for Inland Empire summers. Attic temperatures in Highgrove regularly spike past 140°F, which means under-insulated homes bleed cooled air and force AC systems to run constantly from June through October. We are Orange County Insulation, an insulation-only contractor, and we serve Highgrove homeowners who want the heat stopped at the attic line instead of paying for it every month. Call (877) 680-3557 for a straightforward assessment of what your attic actually needs.
Why Highgrove Homes Are Different
Highgrove sits in the hot, dry stretch of the Inland Empire where insulation work is less about holding heat in and more about keeping it out. The housing stock tells the story: single-story ranch and tract homes built from the 1950s through the 1980s, many still carrying the original fiberglass batts their builders installed. That insulation has settled, compressed, or simply wasn’t thick enough to begin with. Add single-pane windows and older framing, and you have homes that heat up fast and cool down slowly.
The Santa Ana winds change the job further. When those events push through Highgrove, they carry fine dust from the surrounding open land and force hot air through every gap in attic and wall assemblies. We see this constantly: a homeowner has batts in the attic but still gets dust inside, still feels warm rooms, still sees high bills. The problem isn’t just R-value; it’s air leakage. In Highgrove, air sealing is often more valuable than adding more insulation on top of an already leaky assembly. That changes which products we recommend and how we install them. A sealed attic with the right blown-in material performs differently than a dusty, leaky one with premium batts.
Permits in Highgrove fall under Riverside County jurisdiction, and for insulation retrofits, most jobs move forward without a permit when the work is limited to adding material to an existing attic or wall cavity. Any structural change, like converting a vented attic to a sealed one with closed-cell spray foam or adding soffit vents, may trigger a permit review. We handle that conversation for you and know what county inspectors look for.
Our Main Highgrove Services
Highgrove homeowners call us most often about two things: getting their attic insulation upgraded and deciding whether spray foam makes sense for their specific home. Both services solve real problems here, but they solve them differently. Here’s what each involves in Highgrove specifically.
Attic Insulation in Highgrove
Most Highgrove attics we inspect have between R-11 and R-19 of compressed, dusty fiberglass from the original build. That’s roughly a third of what the Department of Energy recommends for this climate zone. Attic insulation work here typically means removing or topping off that old material, air sealing every penetration we can reach, and then blowing in fresh material to a consistent depth across the entire attic floor. The goal is an attic that stops radiating heat into the living space below by late afternoon. For the full breakdown of what this looks like in Highgrove, read our Attic Insulation in Highgrove page.
Spray Foam Insulation in Highgrove
Spray foam in Highgrove is usually chosen by homeowners who are already dealing with dust intrusion from Santa Ana events or who want to turn an attic into conditioned space. Closed-cell foam from Demilec air seals and adds structural rigidity in one pass, which matters on older Highgrove framing. Open-cell Icynene is a better budget fit for sound control and thermal performance in standard attics. The right choice depends on your roofline, your budget, and whether you plan to use the attic. We cover those specifics on our Spray Foam Insulation in Highgrove page.

Blown In Insulation in Highgrove
Blown in insulation is the workhorse solution for Highgrove homes because it fits the local housing stock perfectly. These older ranch homes have attics with odd joist spacing, low clearance, and decades of settled material; blowing in fresh insulation lets us fill every cavity evenly without tearing out ceilings or walls. Loose fill also lets us air seal first, which matters here because Santa Ana winds push dust and hot air through every gap in a Highgrove attic. If your home was built in the 1960s or 1970s and the attic still has the original batts, Blown In Insulation is almost always the fastest, most complete fix.
Cellulose Insulation
Signs you need it
Rooms stay hot long after the sun goes down, and you can see dust accumulating near ceiling vents or light fixtures even with the windows closed.
What it costs in Highgrove
Cellulose blown into a typical Highgrove attic runs $1.20 to $2.30 per square foot installed, depending on depth and whether old material needs removal first.
How we do it
We air seal the attic floor penetrations, then blow GreenFiber cellulose to a consistent depth that hits the R-value target we agree on before starting.
Blown In Attic Insulation
Signs you need it
Your AC runs almost constantly in summer, and the ceiling feels warm to the touch by late afternoon even while the thermostat says the house is cool.
What it costs in Highgrove
Blown in attic insulation for a 1,200 to 1,800 square foot Highgrove ranch typically falls between $1,400 and $3,800 all-in, including air sealing.
How we do it
We remove or top off the old material, seal every penetration in the attic floor, then blow in new insulation at a consistent depth using calibrated hoppers.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old, compressed batts that sit below the tops of the joists, and you want a material that won’t settle again over the next two decades.
What it costs in Highgrove
Blown in fiberglass in Highgrove runs $0.90 to $1.80 per square foot for typical attic depths using Owens Corning or Johns Manville loose fill.
How we do it
We run a hose from the truck to the attic, blow the fiberglass to the target depth, and verify coverage with a depth marker so you can see exactly what you paid for.
What Blown In Insulation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Blown in fiberglass (attic, R-38) | $0.90 – $1.80 per sq ft |
| Blown in cellulose (attic, R-38) | $1.20 – $2.30 per sq ft |

Does blown in insulation help with Highgrove’s summer heat?
Yes. Blown in insulation slows radiant heat transfer from a 140°F attic into your living space, which directly reduces how hard your AC works. Homes with proper attic coverage stay cooler by late afternoon, when Highgrove heat peaks. Call (877) 680-3557 for a free attic assessment.
How long does blown in insulation last in Highgrove’s climate?
Cellulose and fiberglass both perform well in Highgrove’s dry heat. Fiberglass won’t settle noticeably if installed correctly. Cellulose may settle 5 to 10 percent over the first year, then stabilizes. Neither breaks down from heat alone. Call (877) 680-3557 and we’ll help you pick the right one.

What Highgrove Customers Say
"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."
— Nia Robinson"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Mark Schaefer
