Insulation Company in Highgrove, CA
Blown in insulation solves the biggest problem Highgrove homeowners face in our long, hot summers: attic heat that forces your AC to run constantly. Highgrove sits in the inland Inland Empire corridor, where attic temperatures routinely climb past 140°F and older single-story homes lose conditioned air through settled or missing insulation. We install blown in insulation that fills those gaps completely – reaching corners batts can’t – so your cooling bills drop and your rooms stop feeling uneven.

Why Highgrove Homes Are Different
Highgrove’s housing stock is mostly mid-century single-story tract homes with some newer infill mixed in. Those older homes were built when energy was cheap and insulation codes were thin, so we regularly find attics with R-11 fiberglass that has compressed to half its original thickness or drifted away from the eaves entirely. The dry inland heat bakes that material year after year, and once it settles, it stops doing its job. Meanwhile, the newer infill homes often have builders’ minimum insulation and leaky ducts running through unconditioned attic space, so even a ten-year-old home can leak cool air at a startling rate.
The climate here shifts the entire insulation conversation toward heat rejection. In coastal California, insulation marketing often talks about keeping heat in. Highgrove doesn’t need that. We’re worrying about keeping heat out – reflective barriers, high-R attic coverage, and sealing ductwork against 140°F attic air. That’s why our crews start with the attic on nearly every Highgrove job rather than jumping to walls. The attic is where the biggest energy losses happen in this specific pocket of Riverside County.
Because Highgrove is unincorporated Riverside County territory, permit requirements differ from neighboring incorporated cities. Most insulation retrofits in existing homes don’t require a permit, but if you’re planning a larger remodel or addition, we’ll talk through what the county wants before we start. The housing age also means some attics have older wiring or recessed can lights that need air-sealing before we add insulation. We account for that in the bid, not as a surprise later.
Our Main Highgrove Services
Highgrove homeowners call us most about two projects: bringing attic insulation up to current standards and using spray foam to seal problem areas. Here’s what each involves in this community.
Attic Insulation in Highgrove
In Highgrove’s older single-story homes, the attic is where cool air escapes and summer heat pours in. We inspect what’s already up there, then recommend either adding new blown-in insulation over settled material or removing and replacing it entirely, depending on condition. Radiant barrier work pairs naturally with this in Highgrove’s 140°F attic conditions. The goal is a measurable drop in AC runtime during July and August. Attic Insulation in Highgrove covers the full process, from inspection to air-sealing to final depth checks.
Spray Foam Insulation in Highgrove
Spray foam earns its place in Highgrove when attics are converted to living space, when ductwork runs through unconditioned attics, or when homeowners want to turn a hot-roof design into a sealed, conditioned space. Closed-cell foam also adds structural rigidity to older Highgrove roofs. Open-cell foam handles sound dampening in interior walls near busy roads. Both Icynene and Demilec lines come into play depending on the specific R-value target and moisture concern. Spray Foam Insulation in Highgrove explains how we match foam type to the problem.

Blown In Insulation in Highgrove
Blown in insulation is the most common upgrade we perform in Highgrove because it’s the fastest, most cost-effective way to restore thermal performance to an older attic. Highgrove’s mid-century homes almost universally need it – either the original insulation has settled and compressed, or there simply isn’t enough to meet current code. The dry heat accelerates material breakdown, so a 1960s attic that once had R-19 might effectively be performing at R-8 today. Blown in insulation fills every joist cavity and odd-shaped corner without the gaps that batts leave behind, which matters when your attic is hitting 140°F. We can lay a fresh layer over settled material or remove the old stuff first, depending on what we find during inspection. For a deeper look at how blown in insulation works across different housing types, see our Blown In Insulation service hub.
Cellulose Insulation
Signs you need it
You can see the tops of your ceiling joists in the attic, or your insulation looks thin, gray, and powdery rather than fluffy and evenly spread.
What it costs in Highgrove
Cellulose insulation in Highgrove typically runs $1.60 to $3.40 per square foot installed, depending on the depth and whether we remove old material first.
How we do it
We run a hose to the attic, dense-pack or loose-fill the cellulose to the specified R-value, and check coverage with a depth gauge before we call it done.
Blown In Attic Insulation
Signs you need it
Upstairs rooms are consistently hotter than the rest of the house in summer, or your AC runs nonstop and still can’t hold a set temperature.
What it costs in Highgrove
Attic-only blown in insulation in Highgrove generally falls between $1,700 and $2,800 for a typical 1,200-square-foot attic, depending on target R-value and prep work.
How we do it
We air-seal penetrations like can lights and wiring chases, then blow insulation to a consistent depth across the entire attic floor, including the hard-to-reach eaves.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are compressed, water-stained, or pulled back from the eaves, leaving bare drywall exposed to attic heat.
What it costs in Highgrove
Blown in fiberglass in Highgrove typically runs $2.00 to $4.00 per square foot installed for attic coverage, with the final price driven by depth and access.
How we do it
We use an insulation blower to distribute loose fiberglass evenly, checking depth markers throughout to make sure there are no thin spots or bare patches.
Loose Fill Insulation
Signs you need it
Your attic has uneven coverage with visible gaps, or you find piles of old insulation drifted into one corner while other areas sit bare.
What it costs in Highgrove
Loose fill insulation in Highgrove runs $1.60 to $3.20 per square foot installed when adding a new layer over existing material.
How we do it
We fill the attic to a consistent depth, working from the eaves inward so every cavity gets the same R-value and thermal performance.
What Blown In Insulation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Attic inspection and air-sealing | $300 – $700 |
| Blown in attic insulation (1,200 sq ft attic) | $1,700 – $2,800 |

Is blown in insulation worth it in Highgrove’s climate?
Yes, particularly for cooling costs. A properly insulated Highgrove attic can reduce summer cooling load by 20-30% compared to a settled R-11 attic, and the savings compound every July and August. Call (855) 341-6045 for a free estimate.
How long does blown in insulation last in a Highgrove attic?
Cellulose and fiberglass both last decades, but Highgrove’s extreme attic heat accelerates settling, so expect meaningful compression after 15-20 years. An inspection every five years catches thin spots before they cost you. Call (855) 341-6045 to schedule one.

"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Eric Fletcher"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Kelly Meyer"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."
