Insulation Company in Upland, CA
Blown in insulation is the most common fix we install in Upland homes, and the reason comes down to how this city was built. The 1920s-40s bungalows around downtown and the 1970s-80s tracts north toward the foothills were rarely insulated to handle today’s San Bernardino County summers. We see attics with an inch of settled, dust-compacted fiberglass and zero baffles above Euclid-area homes, while 91784 tract houses bake under roofs that hit 140°F by 2 p.m. Hollywood Insulation Co has served Upland since 2018, and we carry eight manufacturer brands so the fix matches the house, not whatever is on the truck.

Why Upland Homes Are Different
Upland sits at the foot of the San Gabriel Mountains where the marine layer gets blocked, so summer heat spikes hard and lingers. Attics in 91784 and the historic downtown core of 91786 routinely exceed 130°F on July afternoons. That heat pushes down into living spaces, and the air conditioner runs for hours just to hold 78°F. We approach Upland insulation differently than a coastal job: R-value targets favor heat rejection, attic ventilation matters more than heating-season performance, and radiant barriers earn their keep when Santa Ana winds dry everything out.
The other Upland-specific reality is housing stock. The citrus-grove-era bungalows near Euclid and Foothill often have original knob-and-tube wiring and no soffit vents at all. Before we blow anything in, we check for air sealing needs and baffle placement. Meanwhile, the 1960s-80s tract homes up toward the San Antonio Heights edge were built to bare-minimum Title 24 standards that have never been upgraded. A few miles apart, two Upland houses might need completely different insulation approaches, and that ZIP-by-ZIP swing is exactly why we carry three installation methods and eight brands. One honest recommendation, matched to the home’s actual needs.
Our Main Upland Services
Most Upland homeowners call us about two things: under-insulated attics that make the second floor unbearable in summer, and air leakage in older walls and rim joists. Here is how each works in this city.
Attic Insulation in Upland
Older Upland attics, especially in 91786, often hold less than R-19 after decades of settling. Add the fact that many pre-1950 bungalows have no soffit ventilation, and you have an attic that traps heat and cooks the ceiling below. We start by evaluating what is up there, often finding baffles missing entirely. Air sealing comes first, then the right R-value for Upland’s heat-dominant climate. Attic Insulation in Upland goes deeper on material options and what we see in foothill-adjacent homes.
Spray Foam Insulation in Upland
For Upland homes with vaulted ceilings, odd framing, or a wildland-edge location above 91784 where ember exposure matters, spray foam earns its place. Closed-cell foam, in systems like Icynene and Demilec, air-seals and insulates in one pass, which is useful when Santa Ana winds drive dust and embers against the building envelope. Spray Foam Insulation in Upland covers the open-cell versus closed-cell decision for this specific climate.

Blown In Insulation in Upland
Blown in insulation is the fastest, most cost-effective way to bring an older Upland attic up to current code. In the 1920s-40s bungalows near downtown and Euclid, we regularly find attics with less than R-10 of settled, dusted-over fiberglass and no baffles to keep soffit vents clear. In the 1970s-80s tract homes pushing toward the foothills in 91784, original Title 24-era insulation often sits at R-19 when Upland’s 100°F-plus afternoons call for R-38 to R-60 in the attic plane. Blown in cellulose or fiberglass fills the joist bays evenly, covers bypasses, and cuts both heat gain and air-conditioning runtime. For the full scope of this method, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, settled, or ashy gray, and rooms below the attic run 8 – 10°F hotter than the rest of the house in a Upland summer.
What it costs in Upland
Blown-in cellulose in a Upland attic typically runs $1.80 – $3.20 per square foot installed, depending on depth and prep work.
How we do it
We air-seal penetrations, install baffles at the eave line to protect any soffit vents, then blow GreenFiber recycled cellulose to the target R-value with a calibrated machine.
Blown In Attic Insulation
Signs you need it
Your energy bills spike from June through September, and the upstairs bedrooms never cool down even after the AC runs all afternoon.
What it costs in Upland
Blown-in attic insulation in Upland generally falls between $1.50 and $3.50 per square foot, with older 91786 homes on the higher end due to air-sealing and vent work.
How we do it
We remove or work around any compromised material, seal top plates and penetrations, mark final depth, and blow fiberglass or cellulose evenly across the full attic floor.
What Blown In Insulation Costs in Upland
| Item | Typical range in Upland |
|---|---|
| Blown-in cellulose (attic, R-38 upgrade) | $1.80 – $3.20 per sq ft |
| Blown-in fiberglass (attic, R-38 upgrade) | $1.50 – $3.00 per sq ft |
| Air sealing and baffle prep before blow-in | $400 – $900 per attic |
How long does blown in insulation take in Upland?
Most Upland attics are done in one day. A typical 1,200 – 1,800 sq ft home takes our two-person crew four to six hours including prep, and you can walk through the house the same afternoon.
Does blown in insulation settle over time in Upland’s heat?
Cellulose settles slightly after install, which is why we install to a compensated depth. Fiberglass settles less. Both hold their stated R-value for decades when installed at the labeled density.

Yes. Some foothill HOAs in 91784 have exterior appearance rules, but attic and wall insulation work is almost always interior and outside HOA review. If a vent or roof addition is part of the job, we coordinate with the HOA contact before scheduling.

What Upland 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."
