Insulation Company in Highland, CA
Blown in insulation is the fastest, most cost-effective way to fix the thin, uneven attic coverage we see across Highland’s 1950s through 1970s tract homes. Most of these houses were built with a thin layer of original batt insulation that has compressed, shifted, or been torn apart by decades of HVAC work and attic traffic. We restore that thermal barrier with loose-fill material that reaches every corner, including the awkward spaces near soffit vents where batts never quite fit.

Why Highland Homes Are Different
Highland sits at the base of the San Bernardino Mountains, squarely in the hot, dry Inland Empire. Summer highs regularly push past 100°F, and attic temperatures in Highland’s single-story stucco ranch homes climb to 140-150°F. That heat radiates into living spaces through the ceiling, making attic insulation the single highest-ROI upgrade for residents in the 92346 ZIP code. Unlike cooler foothill towns up the mountain, Highland’s low elevation and smoggy summer heat mean insulation here is judged almost entirely on how well it blocks heat gain from above. Winter cold is mild, so the priority is summer heat-blocking, not heating retention.
The housing stock reinforces that. Highland’s core is dominated by single-story stucco tract and ranch homes built between the 1950s and 1970s. Original attic insulation in these homes is often a thin layer of batts, now compressed, torn loose by cable and HVAC work, or blown around near soffit vents. Newer subdivisions on the east and north edges, built in the 1990s and 2000s, tend to have code-minimum coverage that still falls short of what Highland’s summer heat demands. In the older tracts especially, the job is less about adding batts on top and more about restoring an even attic blanket that actually covers the whole ceiling plane.
Our Main Highland Services
When Highland homeowners call us, they usually need one of two things: a complete attic insulation upgrade or targeted spray foam for hard-to-seal areas. Here’s what each involves in Highland specifically.
Attic Insulation in Highland
Most Highland homes built before 1990 have underperforming attic insulation, whether it’s compressed original batts or blown-in material that has settled over decades. We remove or top up the existing layer, air-seal the attic floor, and install fresh material matched to the home’s orientation and existing HVAC setup. In Highland’s 140°F summer attics, a consistent R-value across the entire ceiling plane matters more than any single material choice. Attic Insulation in Highland covers the full process and what we check during the walkthrough.
Spray Foam Insulation in Highland
Spray foam earns its keep in Highland’s older homes where can lights, plumbing penetrations, and dropped soffits create air leaks that batts can’t address. Closed-cell foam, in particular, acts as an air barrier and a vapor retarder in one step, which matters in a climate where summer humidity occasionally collides with indoor air conditioning. It’s not the right choice for every Highland attic, but when a home has existing ductwork in a vented attic or a kneewall that’s impossible to seal by hand, foam solves problems other materials can’t. Spray Foam Insulation in Highland explains when it makes sense and when blown-in is the better value.

Blown In Insulation in Highland
Blown in insulation is the workhorse solution for Highland’s older tract homes, where thin original batts have compressed or been disturbed over decades and the attic floor has settled unevenly. Loose-fill material is blown into attics and hard-to-reach wall cavities, filling gaps and creating a uniform thermal blanket across the entire ceiling plane, which is exactly what Highland’s 140-150°F summer attics demand. It’s faster and often more affordable than pulling and replacing batts, and it reaches corners and odd angles that batt rolls simply can’t cover. As a material-agnostic specialist, we work with GreenFiber cellulose and CertainTeed fiberglass, so we can match the material to your home’s existing conditions rather than forcing whichever product happens to be in the truck. Blown In Insulation is one of our core services, and it’s the one we recommend most often for Highland’s 1950s-1970s housing stock.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, there are visible bare spots near soffit vents, or rooms below the attic stay hot well into the evening during Highland summers.
What it costs in Highland
In Highland, blown-in cellulose insulation typically runs $1.10 to $1.80 per square foot installed, depending on depth and existing conditions.
How we do it
We prep the attic by sealing air leaks around can lights and wiring, then blow GreenFiber cellulose to the target R-value using a calibrated machine that ensures even coverage from the eaves to the peak.
Blown In Attic Insulation
Signs you need it
You can see the tops of the ceiling joists in your attic, the existing insulation is uneven or matted down, or your upstairs rooms are 8-10 degrees warmer than the rest of the house in summer.
What it costs in Highland
Blown in attic insulation for a typical Highland ranch home runs $1.00 to $2.00 per square foot, with simple single-story attics landing on the lower end.
How we do it
We remove or top up the existing material, install baffles at the soffit vents to protect airflow, air-seal penetrations, then blow the loose-fill material to a consistent depth across the full attic floor.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts have been disturbed by HVAC or cable work and now sit unevenly against the attic floor, leaving uninsulated gaps along the ceiling plane.
What it costs in Highland
Blown in fiberglass insulation in Highland typically costs $0.90 to $1.60 per square foot installed, depending on the target R-value and attic accessibility.
How we do it
We remove any compressed or damaged batts, run a thorough air-seal pass, then blow CertainTeed fiberglass to the specified depth with a single-engine machine for even distribution.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Blown in cellulose (attic, R-38) | $1.10 – $1.80 per sq ft |
| Blown in fiberglass (attic, R-38) | $0.90 – $1.60 per sq ft |
| Blown in attic insulation (full job) | $1.00 – $2.00 per sq ft |
How long does blown in insulation last in Highland?
Cellulose blown in insulation maintains its R-value for 20-30 years in Highland’s dry climate, and fiberglass can last even longer. The bigger variable is attic disturbance, not material breakdown. If you’ve had HVAC work, rewiring, or a new roof and the material was moved, call (844) 241-0737 for an inspection.
Is blown in insulation enough for a Highland summer?
Yes, when installed to the right depth. We recommend R-38 to R-49 for Highland attics, which typically means 13 to 16 inches of loose-fill material depending on the product. With that depth, the ceiling surface stays measurably cooler and air conditioning runs less. Call us for a free attic assessment at (844) 241-0737.

What Highland Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Gilbert Hernandez"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Paige Ziegler"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."
