Insulation Company in Highland, CA
Blown in insulation is the most common fix we install in Highland attics, and for good reason. The city’s 1950s and 1960s tract homes were built when energy was cheap, so original attic insulation is often an inch of settled fiberglass or nothing at all. Add Highland’s long Inland Empire summers where attic temperatures regularly climb past 150°F, and you get rooms that never cool down and AC units that run constantly. We’re Aliso Viejo Insulation Co, and we’ve been correcting that in Highland since 2014. Call (877) 352-4780 when you’re ready to find out what’s actually in your attic.
Why Highland Homes Are Different
Highland sits right at the foot of the San Bernardino Mountains, which sounds scenic but means the city catches the full weight of Inland Empire heat. Summer afternoons in the 92346 ZIP routinely hit triple digits, and that heat doesn’t stop at the roofline. It moves straight into unconditioned attics, where temperatures can exceed 150°F. That superheated air presses down through whatever insulation exists into living spaces below, and it’s why cooling costs dominate energy bills here in a way coastal homeowners never experience.
The housing stock compounds the problem. Much of Highland was built during the postwar tract boom, and those single-story ranch homes with stucco exteriors and wood-frame construction typically shipped with minimal insulation by modern standards. What was installed fifty or sixty years ago has settled, compacted, or been disturbed by decades of electrical work, recessed light installation, and general attic traffic. We regularly find attics where the original insulation has thinned to an inch or less in the center of the ceiling, with bare spots above recessed lights and along eaves where heat pours in freely. Newer infill homes near the foothills fare better, but they’re the exception, not the rule.
Our Main Highland Services
Most Highland homeowners reach out to us about one of two things: what’s going on with their attic, and whether spray foam makes sense for their particular home. Both have dedicated pages for this area.
Attic Insulation in Highland
Attic work in Highland usually starts with a simple reality: what’s up there is decades old and wasn’t enough when it was new. Highland’s single-story ranch homes from the 1950s through 1970s often have original batt insulation that’s settled to a fraction of its rated thickness. The good news is that attic insulation is the highest-impact improvement for cooling-dominated climates like this one, because stopping heat at the top of the house keeps everything below cooler. We assess what’s there, remove or supplement as needed, and build back to the R-value that makes sense for Highland’s climate zone. For the full picture, see Attic Insulation in Highland.
Spray Foam Insulation in Highland
Spray foam solves problems that batts and blown-in material can’t always reach, and Highland’s older wood-frame construction makes it particularly useful. Those 1960s ranch homes often have irregular attic shapes, rooflines that leave awkward cavities, and existing ductwork running through unconditioned space. Closed-cell spray foam can air-seal and insulate in one pass, which matters in a climate where attic heat is the dominant problem. We install both Icynene and Demilec systems, so the foam chemistry matches the job rather than whatever happens to be on hand. Details are on our Spray Foam Insulation in Highland page.

Blown In Insulation in Highland
Blown in insulation is the workhorse solution for Highland attics because it’s fast, thorough, and priced reasonably even when the existing insulation is a mess. In a 1960s Highland ranch home, original insulation is often compacted under decades of dust, and the blown-in approach lets us fill over it, around it, and into the tight spots along eaves where heat finds its way in. From Rockwool mineral wool for fire resistance to GreenFiber recycled cellulose for homeowners who want an eco-conscious path, we can match the material to the home. Blown in insulation is our specialty at Aliso Viejo Insulation Co, and Highland homeowners have been relying on it since 2014. You can read more about the method on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic feels scorching hot in summer while rooms below never get comfortable, and your cooling bills climb every year.
What it costs in Highland
Expect roughly $1,500 to $3,100 for a typical attic, depending on square footage and how much old material needs to come out first.
How we do it
We remove any compromised material, air-seal the gaps and penetrations, then blow cellulose to a consistent depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
You can see exposed ceiling joists in your attic, meaning your insulation is below the top of the framing, and it’s not stopping any heat at all.
What it costs in Highland
Budget $1,800 to $3,600 for a full attic blanket in a standard Highland ranch home, with the final number driven by square footage and access.
How we do it
We locate the true depth of existing insulation, calculate the R-value required for Highland’s climate, and blow additional material to reach that level across every ceiling bay.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Cellulose attic insulation | $1,500 – $3,100 |
| Blown in attic insulation (full attic) | $1,800 – $3,600 |
| Blown in fiberglass insulation | $1,200 – $2,800 |
How long does blown in insulation last in Highland?
Cellulose and fiberglass both hold up well here, typically 20 to 30 years before settling or moisture takes a measurable toll. Highland’s dry heat is actually kind to the material. The bigger issue is that old insulation was never enough in the first place, so many homeowners upgrade long before the material fails.
Is blown in insulation better than batts for a Highland attic?
For most Highland attics, yes. Blown in material fills around framing, wiring, and recessed light housings without gaps, which is exactly where heat sneaks through in older homes. Batts leave seams and can’t conform to irregular cavities. If you’re not sure which fits your attic, call (877) 352-4780 and we’ll tell you straight.
