Insulation Company in Highland, CA
Blown in insulation is the most common call we get from Highland homeowners, and it’s not hard to see why. Most houses here were built between the 1950s and 1970s, when energy was cheap and insulation was often an afterthought. Now those same ranch homes sit through summers where attic temperatures climb past 140°F, and whatever insulation exists has usually settled into something closer to a thin blanket than a thermal barrier. If your rooms heat up unevenly or your AC runs constantly from June through September, the fix usually starts in the attic. Call North Tustin Insulation at (877) 265-5712 for a straight answer about what your home actually needs.
Why Highland Homes Are Different
Highland sits at the base of the San Bernardino Mountains, far enough inland that the summer sun hits hard and the afternoon heat lingers. Cooling load dominates here. That means insulation work in Highland isn’t just about hitting an R-value – it’s about keeping heat from cooking down through the ceiling all day. The housing stock adds another wrinkle. These 1950s and 1970s single-story tract homes were built fast, often with minimal insulation and gaps around every penetration. Many have had unpermitted additions or converted garages tacked on over the years, which creates irregular thermal envelopes. One room might hold temperature fine while the added-on family room bakes. East of the 210, technicians regularly pull out original rock wool or even newspaper-based insulation that has compressed to R-4 or less. In a 100°F Highland summer, that’s not much better than nothing.
The good news is that blow-in insulation solves exactly this problem well. It fills irregular cavities, covers settled insulation, and brings attic performance up to current code without tearing out walls. North Tustin Insulation has served Highland since 2011, and we’ve seen enough of these attics to know what works here.
Our Main Highland Services
Most Highland homeowners reach out to us for one of two things: upgrading attic insulation in an older home, or air-sealing and insulating with spray foam where traditional materials fall short. Here’s what each involves in Highland specifically.
Attic Insulation in Highland
Highland attics are some of the hottest we work in. That heat doesn’t stay in the attic – it radiates down into living space all afternoon and evening, which is why so many local homes feel fine in the morning and unbearable by 4 p.m. Attic insulation work here typically means removing or topping off settled material, air sealing around ceiling penetrations, and blowing in fresh insulation to current recommended levels. Older ranch homes in the 92346 ZIP respond dramatically to this upgrade. We carry fiberglass, cellulose, and mineral wool options so the recommendation fits your attic, not our inventory. See the full breakdown on our Attic Insulation in Highland page.
Spray Foam Insulation in Highland
Spray foam earns its keep in Highland homes with converted garages, bonus rooms, or additions that were never insulated properly. Open-cell foam air-seals and insulates in one pass, which matters when a room has gaps in the walls or ceiling. Closed-cell adds moisture resistance, useful in attic kneewalls and crawlspaces where humidity collects. Because we carry both Icynene and Demilec spray foam systems, we’re not pushing one product – we match the foam to the job. For Highland homeowners dealing with a room that never holds temperature, spray foam is often the answer. Details on Spray Foam Insulation in Highland.

Blown In Insulation in Highland
Blown in insulation is the workhorse solution for Highland’s older ranch homes. Loose-fill material gets blown into attic floors and wall cavities through a hose, settling into every gap and irregular space that batt insulation can’t reach. In Highland, where many attics still hold original material compressed to R-4 or worse, a blow-in upgrade is dramatic: rooms hold temperature better, the AC cycles less, and upstairs spaces stop feeling like an oven by late afternoon. We use GreenFiber cellulose and Johns Manville or Owens Corning fiberglass, depending on the home. Our crews have performed hundreds of blow-in jobs in Highland since 2011 – see how we approach the work on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
If your attic insulation has settled below the top of the ceiling joists or your energy bills climb every summer, cellulose blow-in is likely overdue.
What it costs in Highland
For a typical 1,200 – 1,500 sq. ft. Highland ranch, expect $1.75 – $3.00 per square foot for installed blown-in cellulose, depending on depth and prep work.
How we do it
We air-seal the attic floor first, then blow GreenFiber cellulose to a uniform depth that hits your target R-value, fluffing it to avoid settling.
Blown In Attic Insulation
Signs you need it
If your ceilings feel warm to the touch in summer or you can see the joists through the old insulation, your attic needs a blow-in upgrade.
What it costs in Highland
Blown-in attic insulation in Highland typically runs $1,500 – $2,800 for a full attic in a 1,200 – 1,500 sq. ft. home, including prep and cleanup.
How we do it
We remove or stabilize any compromised material, seal around recessed lights and penetrations, then blow loose-fill to R-30 or R-38 depth as your attic’s framing allows.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |
|---|---|
| Cellulose blow-in (attic, full coverage) | $1.75 – $3.00 per sq. ft. |
| Fiberglass blow-in (attic, whole home) | $1,500 – $2,800 total |
| Wall cavity blow-in (existing walls) | $2,500 – $4,500 total |
Homes with converted garages or multiple additions cost more because the thermal envelope is irregular and air sealing takes longer. We price every Highland job with a flat, upfront quote – no surprise line items at the end.
How long does blown in insulation last in Highland?
Cellulose and fiberglass blow-in both last 20 – 30 years, but Highland’s extreme attic heat can accelerate settling in fiberglass. Cellulose tends to hold its loft better. An attic inspection every 5 – 7 years catches early settling. Call (877) 265-5712 and we’ll check yours.
Is blown in insulation worth it for a Highland summer?
Yes – Highland attics routinely hit 140°F in summer, and a proper blow-in upgrade cuts cooling costs and evens out room temperatures immediately. Most local homeowners notice the difference within a week. Get an exact quote: (877) 265-5712.

What Highland Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nathan Padgett"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Gabriela Herrera"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
