Insulation Company in Highland, CA
Blown in insulation is the most common request we handle in Highland, and for good reason: the city’s mix of 1950s ranch homes and 1980s stucco tract houses means most attics are under-insulated for the triple-digit heat that sits against the San Bernardino Mountain foothills every summer. We’re Fontana Insulation, and we’ve served Highland since 2011 with blown in, attic, and spray foam insulation installed by our own crews, never subcontracted. Call (866) 271-1602 for a free estimate on any Highland home.
Why Highland Homes Are Different
Highland sits at the base of the San Bernardino Mountains, which means two forces hit homes harder here than in most of the Inland Empire: extreme summer heat reflecting off the foothills, and strong winter winds funneling down the canyons. Insulation in Highland is as much about wind infiltration control and radiant heat rejection as it is about R-value. We regularly find attics in east Highland where Santa Ana winds have blown loose insulation to one side or compressed it against the eaves, leaving half the ceiling with almost no thermal barrier. That’s a specific failure pattern we see far more often in Highland than in Redlands or San Bernardino.
The housing stock compounds the problem. Homes near the historic core along Baseline date to the 1950s and 1970s, with low-pitch attics and original or thin insulation that’s settled over decades. East Highland’s 1980s and 2000s tract homes have stucco over wood frame, which handles heat differently than the older ranch homes but often lacks wind-washing barriers at the eaves. Neither style was built with the energy loads Highland sees now, so our approach starts with understanding which era your home belongs to before we recommend a material.
Our Main Highland Services
Most Highland homeowners call us about two things: attic insulation and spray foam. Here’s what each involves in this city.
Attic Insulation in Highland
Attic insulation in Highland usually means re-leveling what the wind has displaced, adding wind baffles at the eaves, and then bringing the attic to a proper R-value for the foothill heat. In east Highland, we often find original blown insulation compressed under newer decking, which reduces its thermal performance dramatically. We carry fiberglass from Owens Corning, Johns Manville, Knauf, and CertainTeed, plus Rockwool mineral wool and GreenFiber cellulose, so the recommendation matches your attic’s specific condition rather than what we happen to have on the truck. See the full breakdown on our Attic Insulation in Highland page.
Spray Foam Insulation in Highland
Highland’s wind problem makes spray foam a compelling option for certain homes here, especially where canyon winds push through wall cavities and rim joists that fiberglass can’t seal. Closed-cell foam from Icynene or Demilec creates an air barrier, not just insulation, which matters when wind-driven air movement is your biggest comfort problem. It’s not the right answer for every Highland attic, but for additions, knee walls, and crawlspace band joists in older ranch homes, it often is.

Blown In Insulation in Highland
Blown in insulation in Highland solves a specific problem: attics with uneven coverage, settled material, or wind displacement that leaves parts of the ceiling barely insulated. The 1950s and 1970s ranch homes near the historic core often have original loose fill that’s compacted to a fraction of its original depth. East Highland’s newer stucco homes tend to have thin builder-grade insulation that was never adequate for highland heat. Our crews re-level, add, and air-seal so the thermal boundary is continuous across the entire attic floor. If you’re unsure what condition your attic is in, call (866) 271-1602 and we’ll inspect it. You can also read more about the service on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
You want a recycled-content option with strong sound-dampening and your attic already has loose fill that’s settled unevenly.
What it costs in Highland
Blown in cellulose insulation in Highland typically runs $1.20 to $2.50 per square foot, including removal of compromised old material when needed.
How we do it
We remove any wind-compressed or rodent-soiled material, air-seal penetrations, install wind baffles at the eaves, and blow GreenFiber cellulose to the target depth across the attic floor.
Blown In Fiberglass Insulation
Signs you need it
Your attic has bare or thin spots, your energy bills climb every July and August, or wind events have visibly shifted existing insulation.
What it costs in Highland
Blown in fiberglass insulation in Highland generally runs $1.10 to $2.30 per square foot, depending on target R-value and attic accessibility.
How we do it
We air-seal the attic floor, verify baffle placement, and blow fiberglass from Owens Corning, CertainTeed, Johns Manville, or Knauf to a consistent, code-aligned depth.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Blown in cellulose (attic) | $1.20 – $2.50 per sq ft |
| Blown in fiberglass (attic) | $1.10 – $2.30 per sq ft |
| Removal of old, wind-compressed insulation | $1.00 – $2.00 per sq ft |
Is blown in insulation worth it for a 1960s ranch in Highland?
Usually yes. Those homes were built when R-11 was standard, and decades of settlement plus Santa Ana wind displacement leaves many Highland ranches with effective R-values well below that. Re-blowing the attic changes comfort within days. Call us for an inspection at (866) 271-1602.
How long does blown in insulation last in Highland’s heat?
Fiberglass and cellulose both last decades when kept dry and protected from wind. The bigger issue in Highland is displacement, not degradation. We install wind baffles to keep canyon winds from shifting material toward the eaves over time.
Brands We Service in Highland
Fontana Insulation stocks and installs eight insulation brands across four material categories, and we carry them because each one earns its place. Rockwool mineral wool for fire resistance and sound control, CertainTeed and Owens Corning fiberglass for dependable thermal performance, and Icynene and Demilec spray foam for air-sealing where blanket materials fall short. Common stock for Highland jobs is on our trucks daily, so most projects start within days of the estimate. See the full lineup on our brands page.

FAQs About Insulation Company in Highland
Most insulation retrofit work in Highland does not require a city permit, since it’s not structural. However, if your project includes new ductwork, significant electrical changes, or added square footage, a permit may apply. We can tell you during the estimate whether your specific job needs any city approval.
Most Highland blown in insulation jobs start within three to five business days of your approved estimate. If you have an empty home or an open attic, we can often move sooner. Call (866) 271-1602 and we’ll give you a specific date on the call.
Attic and interior insulation work rarely triggers HOA review in Highland. Where a covenant requires specific materials or color matching for visible work, we’ve handled those requirements before. We check the specific HOA rules before we start so you don’t get a violation notice later.
If your Highland home is hot in summer, drafty in winter, or showing the signs of wind-displaced attic insulation, call Fontana Insulation at (866) 271-1602. Estimates are free, the recommendation is material-agnostic, and the crew that installs is our own.

— Holly Mercer"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
