Insulation Company in Highland, CA
Blown in insulation is the workhorse retrofit for Highland’s 1950s through 1980s tract homes, where thin original attic batts leave ceilings baking under Inland Empire sun and AC units running nonstop from June through September. We install loose-fill fiberglass and GreenFiber cellulose at depths that bring attics up to current Title 24 levels, cutting the heat load that pushes down into living space all afternoon. Call (866) 605-6949 for a free estimate from a dedicated insulation specialist who works in 92346 regularly.
Why Highland Homes Are Different
Highland sits at the base of the San Bernardino foothills on the hot, dry east side of the valley. Summer design temperatures push well past 100°F, and attics here routinely bake to 150°F or higher on July afternoons. That changes the insulation conversation entirely. In Highland, we’re not chasing winter heat retention. We’re stopping solar heat gain from radiating down through ceilings and turning the second floor into an oven by 5 p.m.
The housing stock compounds the problem. Highland is heavily single-family wood-frame tract homes built between the 1950s and 1980s, many with low-pitched composition-shingle roofs that absorb full sun all day. A lot of these attics still have original R-11 batts, unsealed can lights, and gable vents that don’t move enough air. Add Santa Ana winds and foothill dust, and you get attics where thin insulation is both underperforming and filthy. The defining retrofit in 92346 is bringing attic depth up to R-38 or R-44 and sealing the bypasses that let hot attic air drop into wall cavities.
Our Main Highland Services
Highland homeowners call us most about two jobs: attic insulation retrofits for older tract homes, and spray foam for newer foothill builds or rooms where air sealing matters as much as R-value. Here’s what each involves locally.
Attic Insulation in Highland
Most Highland attic jobs start with removing heat-damaged or dust-loaded old batts, air sealing penetrations like can lights and top plates, then installing fresh insulation at a depth that actually holds up to 150°F afternoons. We match the material to the attic: blown-in fiberglass or cellulose over batt in most cases, with attention to ventilation so the roof deck isn’t cooking the new insulation. See the full local breakdown on our Attic Insulation in Highland page.
Spray Foam Insulation in Highland
Foothill-edge homes and newer Highland subdivisions often benefit from spray foam where the roofline or knee walls need both R-value and air sealing in one pass. Icynene open-cell and Demilec closed-cell give us two different tools depending on whether the job is about sound, moisture, or maximum R-value per inch. Read the Highland-specific details on the Spray Foam Insulation in Highland page.

Blown In Insulation in Highland
Blown in insulation is the fastest, most cost-effective way to fix a Highland attic that still has thin original batts or bare spots over bedrooms. We use loose-fill fiberglass or GreenFiber recycled cellulose to bring coverage up to R-38 or deeper, which directly cuts the ceiling heat load that makes afternoon rooms unbearable and AC bills climb all summer. Because most 1950s – 1980s Highland homes were built with shallow attic access and awkward rafter bays, blowing insulation is almost always more practical than trying to fit new batts into spaces that were never designed for modern R-values. You can read more about the method itself on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic insulation looks flat and papery, you can see ceiling joists poking through, and upstairs rooms run 8 – 10 degrees hotter than downstairs on summer afternoons.
What it costs in Highland
Cellulose attic blow-ins in Highland typically run $1.20 – $2.20 per square foot of attic floor, including removal of old, compressed material where needed.
How we do it
We vacuum out or push aside failed material, seal can lights and top plates, then blow GreenFiber cellulose to a verified depth at the specified R-value.
Blown In Attic Insulation
Signs you need it
Rooms under the attic are the hottest in the house, your attic has batts that are torn, displaced, or only a few inches thick, and your AC short-cycles without ever cooling those rooms.
What it costs in Highland
A full blown in attic insulation retrofit in Highland typically lands between $1,500 and $4,800 depending on attic square footage, access difficulty, and whether old insulation must be removed first.
How we do it
We assess existing R-value, remove or top up as the attic needs, seal the major bypasses, then blow insulation to target depth with baffles protecting every soffit vent.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Cellulose attic blow-in, per sq ft | $1.20 – $2.20 |
| Fiberglass loose-fill blow-in, per sq ft | $1.00 – $2.00 |
| Full attic blow-in retrofit (typical Highland home) | $1,500 – $4,800 |
Will blown in insulation actually lower my AC bill in Highland?
Yes, when the attic is the main heat source. Highland attics hit 150°F in summer, and bringing ceiling insulation from R-11 to R-38 cuts heat transfer into the house by roughly two-thirds, which shows up directly in cooling costs.
How long does a Highland attic blow-in take?
Most 1,200 to 1,800 square foot Highland attics are done in a single day, including setup, air sealing, blowing, and cleanup. Tight attic access or old insulation removal can add a few hours. Call (866) 605-6949 for a firm timeframe.

FAQs About Insulation Company in Highland
Most insulation retrofits in Highland do not require a building permit, since they’re considered maintenance or minor upgrades rather than structural changes. If your project is part of a larger remodel that already has permits, the insulation scope is typically folded into that approval. We handle the work to current Title 24 energy standards either way.
We schedule estimates across 92346 on a same-week basis in most cases. During summer heat waves, we prioritize homes with failed or missing attic insulation. Call (866) 605-6949 and we’ll give you a specific day and arrival window for your Highland address.
Yes. We work in Highland HOAs regularly and know the typical rules about roof-visible vents, access hours, and exterior cleanup. Most insulation work happens inside the attic, so HOA approval is rarely required, but we’ll follow the specific requirements of your community if exterior work like vent replacement is part of the job.

What Highland Customers Say
"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Miguel Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
