Insulation Company in Highgrove, CA
Blown in insulation is the most common upgrade we handle in Highgrove, and for good reason: the ranch-style tract homes and older bungalows that fill the 92313 ZIP were built when attic insulation meant a thin layer of fiberglass batts that has long since settled, compressed, or been shoved aside by decades of HVAC work. In a basin where summer attic temperatures routinely pass 150°F, that missing coverage means heat pours through the ceiling and your air conditioner runs constantly. Birch Insulation serves Highgrove with material-matched blown in insulation, spray foam, and attic insulation, installed in-house. Call (866) 511-7592 for a free estimate.
Why Highgrove Homes Are Different
Highgrove sits in the Inland Empire’s hot semi-arid basin, where the insulation problem is mostly one-directional: keeping summer heat out. Long stretches of 100°F-plus days bake low-pitch roofs all afternoon, and the attics under them become ovens. We regularly measure attic temperatures in the 140 – 160°F range during July and August. That heat radiates down through the ceiling into living spaces, forcing air conditioners to fight a battle they can’t win. The winter side of the equation is mild, so the traditional “keep warm air in” pitch that drives insulation sales in colder climates doesn’t apply here. Highgrove’s insulation challenge is radiant heat gain and HVAC protection, which changes which materials make sense.
The housing stock compounds the problem. Most homes in Highgrove are mid-20th-century wood-frame stucco ranchers with low-pitch roofs, single-pane windows, and attic floors that got the bare minimum of insulation when they were built. Many attics still have original R-11 or R-19 fiberglass batts that have settled into useless thin mats. Wall cavities in the older farmworker-era bungalows often lack modern vapor barriers entirely. What this means in practice: a home in Highgrove with “some insulation” is often losing more cooling dollars than a completely uninsulated home in a milder climate. The local hook is also unique – Title 24 energy standards now push higher attic floor R-values across California, which means many Highgrove homeowners find their existing setup isn’t just inefficient, it’s below what current code expects.
We also see a specific pattern here: original fiberglass batts have been compressed or moved by decades of service work, so a simple top-up often isn’t enough. In many Highgrove attics, we recommend adding a radiant barrier alongside new blown in insulation. The reflective surface bounces radiant heat back out before it can soak into the insulation below, which is exactly what a 150°F attic needs.
Our Main Highgrove Services
Two services account for most of the calls we get from Highgrove homeowners: attic insulation upgrades and spray foam applications for particularly difficult areas. Here’s what each one looks like in this part of the Inland Empire.
Attic Insulation in Highgrove
Attic insulation in Highgrove usually means removing or topping up whatever’s already up there with blown in material matched to the home’s construction. In these older ranchers, we typically find settled fiberglass batts that need to come out before we can bring the attic floor up to current Title 24 expectations. Low-pitch roofs make access tighter than in newer homes, so our crew takes extra care with baffles and ventilation checks while they’re up there. The payoff is immediate in summer: a properly insulated attic keeps the ceiling surface noticeably cooler and lets the HVAC system cycle normally instead of running nonstop. See our dedicated page on Attic Insulation in Highgrove for the full breakdown of materials, process, and local pricing.
Spray Foam Insulation in Highgrove
Spray foam handles the jobs blown in insulation can’t do well: sealing rim joists, insulating hard-to-reach wall cavities, and creating an air barrier in spaces where heat and smog both push through. In Highgrove’s older bungalows with no vapor barriers in the walls, closed-cell spray foam acts as insulation and vapor retarder in one step. It’s also the right call for attics with ductwork running through them, which is common in the ranch homes here. We install both open-cell and closed-cell foam, backed by Icynene and Demilec, depending on what the space actually needs.

Blown In Insulation in Highgrove
Blown in insulation in Highgrove is the workhorse solution for older attics that have lost coverage over the years. In the 92313 ZIP’s ranch houses and bungalows, original fiberglass batts have usually settled to a fraction of their original R-value, leaving the ceiling as a direct conduit for the 150°F attic heat above it. Blown in material gets into all the corners, gaps, and irregular spaces that batts never covered even when new. For most Highgrove homes, a full blown in attic insulation job with air sealing is the single highest-impact upgrade a homeowner can make before next summer. That’s the core service from our Blown In Insulation team, installed in-house with material matched to your home, not just what’s on the truck.
Cellulose Insulation
Signs you need it
Your upstairs rooms or ceiling surfaces get hot to the touch by mid-afternoon even with the air conditioning running.
What it costs in Highgrove
Cellulose blown in for a typical Highgrove attic runs $1,200 – $3,600 depending on square footage, depth, and how much old material needs removal first.
How we do it
We remove any compromised old insulation, air-seal the bypasses, and blow GreenFiber cellulose to the R-value your home needs, including a radiant barrier when the roof design benefits from it.
Blown In Attic Insulation
Signs you need it
You can see the joists in your attic because the old insulation has settled below the top of the framing.
What it costs in Highgrove
Blown in attic insulation for a 1,200 – 1,800 sq ft ranch in Highgrove typically lands between $1,500 and $4,500 with removal of old batts.
How we do it
We blow loose fill across the entire attic floor to a consistent depth, keeping soffit vents clear and verifying coverage with depth markers installed every few feet.
Blown In Fiberglass Insulation
Signs you need it
Your energy bills spike every summer and the air conditioner runs longer cycles than it used to, even after service calls come back clean.
What it costs in Highgrove
Blown in fiberglass for a standard Highgrove attic floor runs $1,000 – $3,200 depending on the target R-value and attic access.
How we do it
We install Owens Corning or Johns Manville loose-fill fiberglass to the specified depth, using an in-house crew that handles the whole job from prep to cleanup.
Loose Fill Insulation
Signs you need it
Parts of your attic have no insulation at all, usually in corners, over additions, or around recessed lights.
What it costs in Highgrove
Loose fill insulation for irregular or partial coverage in Highgrove runs $900 – $2,800 depending on square footage and how much prep work the space requires.
How we do it
We blow loose fill into every cavity and corner, building up depth in thin areas and using a blower setting that prevents over-compaction.
What Blown In Insulation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Cellulose blown in, full attic | $1,200 – $3,600 |
| Fiberglass blown in, full attic | $1,000 – $3,200 |
| Attic top-up over existing insulation | $800 – $2,400 |

If your attic has old insulation that needs removal, a very low-pitch roof that slows access, or you’re adding a radiant barrier, the job moves toward the upper end. Call (866) 511-7592 and we’ll give you an exact number before any work starts.
Is blown in insulation worth it in Highgrove’s climate?
Yes, and it’s often the best dollar-for-dollar upgrade available. Highgrove’s summer attic heat is relentless, and blown in coverage restores the thermal barrier that settled batts lost decades ago. Most homeowners notice lower cooling bills the first full summer after installation.
Can you blow insulation into existing walls in Highgrove?
We can, and it’s a common request for the older bungalows that lack wall insulation. The process involves drilling small access holes through stucco or siding, blowing in material, and patching to match. Call us for an assessment of your specific wall construction.

What Highgrove Customers Say
"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."
— Neil Hayes"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."
— Allen Kim"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Katie Whitaker
