Insulation Company in Highland, CA
Blown in insulation is the most common fix we install in Highland, and for good reason: the city’s mid-century ranch homes were built when energy was cheap and attics were an afterthought. Most still have their original fiberglass batts, now compressed, sagging, or simply inadequate for summers that push attic temperatures past 150°F. We’re an insulation-only contractor, which means every estimate, every crew member, and every material decision focuses on one trade: getting your home’s thermal envelope right. Call us at (877) 680-3557 to schedule a free estimate.
Why Highland Homes Are Different
Highland sits at the base of the San Bernardino Mountains in the hot, dry Inland Empire. Summer attic temperatures routinely exceed 150°F here, which changes the whole insulation conversation. In most of the country, R-value is about holding heat in during winter. In Highland, the real fight is radiant heat from unshaded south- and west-facing roofs baking your attic all afternoon. The older ranch homes along the base-of-the-foothills blocks in 92346 were built for a pre-air-conditioning climate, and many gain most of their heat through the roof, not the walls or windows.
On foothill-adjacent streets, our techs routinely find original R-11 batts compressed or sagging under decades of heat and dust. The real fix often starts with ventilation and radiant barrier before adding a single new batt. Highland’s housing stock is dominated by single-story ranch and tract homes from the 1960s through 1980s, many with low-pitch roofs and minimal attic ventilation, plus a growing share of newer infill construction near the foothills. The newer homes have their own issues: rushed builder-grade insulation that settled quickly and left gaps around can lights and plumbing penetrations. Blown in insulation handles all of these conditions well because it conforms to the irregular shapes in older attics and fills gaps that batts simply can’t reach.
Our Main Highland Services
Highland homeowners typically call us about two insulation services: attic insulation and spray foam. Here’s how each one works in this climate and housing stock.
Attic Insulation in Highland
Attic insulation is the single biggest energy-loss zone in most Highland homes, especially the mid-century ranches with low-pitch roofs and minimal venting. In this climate, we’re not just adding thickness; we’re matching the right material to a roof that gets hammered by sun, plus evaluating whether ventilation and radiant barrier need to come first. We work with fiberglass batts, cellulose, and mineral wool depending on the attic’s condition, and every option comes from manufacturers like Owens Corning, Johns Manville, or Rockwool. For a full breakdown of material choices, attic-specific pricing, and what to expect on the day of install, see our Attic Insulation in Highland page.
Spray Foam Insulation in Highland
Spray foam earns its keep in Highland attics that double as semi-finished storage or house HVAC equipment. Closed-cell foam from Demilec and open-cell foam from Icynene both seal air leaks that batt insulation can’t touch, cutting the stack effect that pulls hot attic air into living spaces during triple-digit afternoons. For homes along the foothills where Santa Ana winds drive dust and heat through every crack, spray foam is often the definitive fix. Read about the differences between open-cell and closed-cell, local pricing, and typical timelines on our Spray Foam Insulation in Highland page.

Blown In Insulation in Highland
Blown in insulation is the most practical retrofit for most Highland homes because it goes in fast, fills the irregular spaces in old ranch-style attics, and costs less than spray foam while delivering a real performance jump. Most 1960s and 1970s tract homes here have attics with original batts that have sagged or compressed, and blown in material can be installed right over the top or after removal, depending on what we find. We install both cellulose and fiberglass blown in insulation, and the right choice depends on your attic’s condition, your budget, and whether you’re dealing with moisture or pest concerns. Our Blown In Insulation service covers everything from spot fills to full attic re-insulation, and we’ll tell you exactly which material fits your situation and why.
Cellulose Insulation
Signs you need it
You feel heat radiating through your ceilings on summer afternoons, or your attic has old, settled insulation that no longer reaches the tops of the joists.
What it costs in Highland
Cellulose blown in insulation typically runs $1.05 to $1.85 per square foot installed, depending on depth and whether we’re removing old material first.
How we do it
We prep the attic by sealing gaps around penetrations, run the hose up, and blow GreenFiber cellulose to the specified depth, using density markers to ensure consistent coverage everywhere.
Blown In Fiberglass Insulation
Signs you need it
Your attic has inconsistent coverage, with visible gaps or bare spots where heat pours in, or you want a budget-friendly option that still beats your current R-value.
What it costs in Highland
Blown in fiberglass typically costs $0.85 to $1.65 per square foot installed in Highland attics, and the final number depends on the target R-value and access.
How we do it
We use loose-fill fiberglass from brands like Owens Corning or Knauf, blown with calibrated equipment to hit your target R-value without over-fluffing or leaving voids.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Blown in fiberglass (attic, R-38) | $0.85 – $1.65 per sq ft installed |
| Blown in cellulose (attic, R-38) | $1.05 – $1.85 per sq ft installed |
| Full attic prep (sealing, baffles, removal) | $350 – $900 depending on attic size and condition |
How long does blown in insulation take in Highland?
Most Highland attics are done in one day, typically four to six hours for an average ranch home. Prep work like air sealing or removing old batts adds time, but we’ll tell you the schedule before we start.
Is blown in insulation worth it in Highland’s climate?
Yes, especially when paired with proper ventilation and radiant barrier. Blown in cellulose or fiberglass at R-38 or higher can cut cooling costs noticeably in a city where summer attic heat is the primary problem. Call (877) 680-3557 for a free estimate.
