Insulation Company in Highland, CA
Blown in insulation is one of the smartest moves a Highland homeowner can make, especially in the mid-century and ranch-style tract homes that dominate this city at the base of the San Bernardino Mountains. Those homes were built when attic insulation was an afterthought, and decades of Inland Empire heat have done the rest. We match each house to the right material rather than pushing whatever is easiest, because a Highland attic that hits 140°F in July needs a different solution than a mild coastal home ever will. Call us at (855) 382-3925 for a free estimate.
Why Highland Homes Are Different
Highland sits where the San Bernardino Valley starts climbing toward the foothills, and that geography shapes every insulation decision here. Summers are long and brutally hot, with attic temperatures routinely exceeding 150°F in exposed roof decks. Winters are mild enough that heating retention is a secondary concern. What this means in practice: the insulation work that pays off fastest in Highland is the kind that blocks radiant heat from pushing down into living spaces.
The housing stock adds another layer. Most of Highland’s single-family homes were built between the 1950s and 1980s, wood-framed and ranch-style, with original fiberglass batts that have settled, compressed, or been disturbed by rodents. In the older foothill neighborhoods, it is common to find three or four inches of insulation where today’s standards call for far more. Equally often, soffit and ridge vents are undersized or blocked, so the attic becomes a heat trap regardless of R-value. The fix is rarely as simple as adding more of the same material. It is matching the insulation type and ventilation to the specific house.
Santa Ana winds and wildfire exposure are part of life in Highland too. That makes fire-resistant insulation choices and proper air sealing more than a preference here. They are a practical response to the environment.
Our Main Highland Services
Most Highland homeowners reach out to us for one of two things: a full attic insulation upgrade or a spray foam install that seals and insulates in one pass. Here is how each works locally.
Attic Insulation in Highland
An attic insulation job in Highland usually starts because bedrooms get stuffy by early afternoon and the air conditioner runs without a break from June through September. In the older ranch homes near the foothills, we commonly find thin, settled fiberglass and soffit vents that are painted over or stuffed with debris. The fix involves upgrading the attic floor insulation and restoring ventilation so heat actually leaves the space. This is the single highest-impact project for cutting summer cooling bills in a typical Highland tract home. Learn more about Attic Insulation in Highland.
Spray Foam Insulation in Highland
Spray foam answers a different problem: air leaks. Highland’s wood-framed homes have dozens of small gaps around top plates, recessed lights, and plumbing penetrations that let hot attic air pour into the house. Spray foam seals those gaps and insulates at the same time, which is why it performs so well in this climate. It is especially useful in the low-slope roof sections common on late-century Highland builds where batts are awkward to install correctly. We use Icynene and Demilec open- and closed-cell systems for this work. See Spray Foam Insulation in Highland for details.

Blown In Insulation in Highland
Blown in insulation in Highland solves a very specific local problem: the original attic insulation in these 1950s-to-1980s tract homes has settled into a thin, uneven layer that barely slows the summer heat. Blown in material, whether GreenFiber cellulose or fiberglass, fills the entire attic floor to a uniform depth, including the odd corners and shallow cavities that batts can never reach properly. That full, consistent coverage is what changes how a house feels by late afternoon. As a full-service Blown In Insulation contractor, we install both cellulose and fiberglass blown systems, matched to what your attic actually needs.
Cellulose Insulation
Signs you need it
Your attic has uneven, patchy insulation with visible gaps, and rooms at the end of long duct runs are consistently hotter in summer.
What it costs in Highland
Blown in cellulose for a typical 1,200 to 1,500 square foot Highland attic runs $1.25 to $2.10 per square foot, including installation.
How we do it
We remove any damaged existing material if needed, air-seal the major leak points, then blow GreenFiber cellulose to a uniform depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
Your attic insulation is compressed below the top of the floor joists, or you can see bare drywall in patches where wind or pests have moved the material.
What it costs in Highland
Blown in attic insulation in Highland generally falls between $1,150 and $2,800 for a complete attic floor, depending on square footage and access difficulty.
How we do it
We vacuum out any contaminated or compressed material, seal ceiling penetrations, then blow new insulation to the depth your attic design requires, including baffles at the eaves.
Blown In Cellulose Insulation
Signs you need it
You want an eco-conscious option with recycled content, and your existing fiberglass batts have settled into ineffective, dust-covered slabs.
What it costs in Highland
Blown in cellulose for the attic floor of a ranch-style Highland home typically lands between $1.25 and $2.10 per square foot installed.
How we do it
We dense-pack or loose-fill GreenFiber cellulose depending on the cavity, which gives fuller coverage in the shallow, irregular attic spaces common in older Highland homes.
Blown In Fiberglass Insulation
Signs you need it
Your current fiberglass batts are torn, moisture-stained, or housing rodent droppings, and you want a clean replacement that will not settle as fast.
What it costs in Highland
Blown in fiberglass in Highland runs $1.10 to $1.75 per square foot for attic floor installation, with full removal of old material adding slightly more.
How we do it
We remove the failed material, install any needed ventilation baffles, and blow fresh fiberglass to a consistent depth, fluffed properly to hold its R-value over time.
Loose Fill Insulation
Signs you need it
Your attic has shallow joist bays, cross-bracing, or many irregular cavities where pre-cut batts leave gaps and cold or hot spots.
What it costs in Highland
Loose fill insulation for a Highland attic costs between $1.10 and $2.10 per square foot depending on material choice and depth required.
How we do it
We blow the loose fill material into every cavity, working around framing and utilities without compressing it, so the coverage is genuinely continuous.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Blown in fiberglass (attic floor) | $1.10 – $1.75 per sq ft |
| Blown in cellulose (attic floor) | $1.25 – $2.10 per sq ft |
| Complete attic for ranch or tract home | $1,150 – $2,800 |
Two things push blown in insulation costs up in Highland. First is attic access: many older ranch homes have small scuttle holes in a closet ceiling, which slows the work and sometimes needs enlarging. Second is cleanup from prior rodent activity or old, dusty fiberglass that must be removed before new material goes in.
Is blown in insulation better than batts for a Highland attic?
For most older Highland attics, yes. Blown in material fills the full joist bay without gaps or compression, which is exactly what aging tract homes with irregular framing need.
Can you blow insulation over existing attic insulation in Highland?
Sometimes, if the existing material is dry, clean, and not compressed. We assess it during the estimate and tell you honestly whether it should be removed first. Call (855) 382-3925 to schedule a look.

What Highland Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Jason Hoffman"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."
— Colleen Vaughn"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."
— Amanda Sullivan
