Insulation Company in Upland, CA
Blown in insulation is the most common retrofit we handle in Upland, and for good reason. The older ranch and mid-century homes around downtown and the 91786 core usually have thin, settled attic material that no longer performs, while foothill homes in 91784 and 91786 bake under intense Inland Empire sun. We match each Upland home to the right material, whether that’s loose-fill fiberglass, GreenFiber cellulose, or a spray foam upgrade. If your rooms feel uneven or your AC runs nonstop from June through September, call (855) 382-3925 and we’ll take a look.
Why Upland Homes Are Different
Upland sits at the foot of the San Gabriel Mountains, and that location shapes everything about how insulation should be specified here. Summer heat radiating off the foothills pushes attic temperatures well past 140°F in July and August, especially on south- and west-facing exposures above the 210. At night, temperatures can drop 30 degrees or more. That diurnal swing means insulation has to do two jobs well: resist heat gain during the day and hold warmth when the evening cools down.
The housing stock compounds the challenge. Near downtown Upland, we work in a lot of postwar and mid-century tract homes with original ceilings and barely three to four inches of settled insulation. Up in 91784, newer two-story homes look better on paper but often carry builder-grade R-values chosen for code minimums, not for actual comfort. Attics above the 210 run hotter than almost anywhere else we serve, and we regularly find blown-in material compressed and settled after years of heat cycling.
Our Main Upland Services
Most Upland homeowners who call us are dealing with one of two situations: an attic that’s underperforming or a home that needs air-sealing performance beyond what fiberglass can deliver. Here’s how each service works in Upland specifically.
Attic Insulation in Upland
Attic work in Upland usually means either topping off old, compressed material or pulling it out and starting fresh. In the 91786 core, we frequently find original batt insulation from the 1960s and 70s that has sagged away from the roof deck. In foothill neighborhoods, radiant heat is the bigger issue, and material choice matters more. We assess what’s already up there, check for settled or compressed areas, and recommend the right depth and material for the specific exposure. See Attic Insulation in Upland for the full breakdown of how we approach these jobs.
Spray Foam Insulation in Upland
Spray foam earns its keep in Upland when air movement and heat gain are the real problems, not just depth of coverage. Open-cell foam does a strong job air-sealing older ranch homes with leaky top plates and can lights, while closed-cell systems from Icynene and Demilec make sense for attics that get hit hard by afternoon sun. Foam also helps stabilize temperatures in bonus rooms and second-story spaces that never seem to reach the thermostat setting. Read Spray Foam Insulation in Upland for more on the two systems and where each fits.

Blown In Insulation in Upland
Blown in insulation is our most-requested service in Upland because it’s the fastest, most effective way to fix an under-insulated attic without tearing anything apart. We blow loose-fill fiberglass or GreenFiber cellulose over existing material to reach a proper depth, or remove old, settled material and start clean when it’s beyond saving. In Upland’s dry heat, compressed blown-in material from decades of thermal cycling is one of the most common reasons rooms feel hot on the second floor even when the thermostat says otherwise. For a fuller look at how the method works and the materials we use, visit Blown In Insulation.
Cellulose Insulation
Signs you need it
Your attic has thin, patchy coverage and you’d prefer a recycled-content material that also dampens sound between floors.
What it costs in Upland
Cellulose blown-in attic work in Upland typically runs $400 to $1,800 depending on attic size and existing depth.
How we do it
We prep the attic, seal bypass points like wire chases and top plates, then blow GreenFiber cellulose to a consistent, even depth across the full floor.
Blown In Attic Insulation
Signs you need it
Rooms run noticeably warmer than the thermostat setting, and you haven’t added attic insulation since the home was built.
What it costs in Upland
Blown-in attic jobs in Upland generally land between $400 and $1,800, with larger foothill attics in 91784 at the upper end.
How we do it
We measure existing depth, check for settling and gaps, then blow loose-fill material to the R-value that fits your home’s ceiling type and sun exposure.
Blown In Cellulose Insulation
Signs you need it
You want better temperature stability and a product made from recycled paper instead of fiberglass.
What it costs in Upland
Blown-in cellulose in Upland typically ranges from $400 to $1,800 for a standard attic, before any removal of old material.
How we do it
We run a hose into the attic and blow cellulose to the target depth, checking density as we go so coverage stays uniform wall to wall.
Loose Fill Insulation
Signs you need it
Your attic has settled, compressed patches and bare spots, leaving parts of the ceiling warm to the touch in summer.
What it costs in Upland
Loose fill attic coverage in Upland runs $400 to $1,800, with multiple-story homes calling for more material and time.
How we do it
We blow loose fill over the existing layer after confirming it’s dry and intact, building depth evenly and keeping air chases clear.
What Blown In Insulation Costs in Upland
| Item | Typical range in Upland |
|---|---|
| Blown-in attic insulation (standard ranch) | $400 – $1,200 |
| Blown-in attic insulation (large or two-story foothill home) | $1,200 – $1,800 |
| Attic air sealing before blow-in | $200 – $700 |
Older Upland attics with settled material or rodent damage sometimes need removal first, which adds cost. We give you a flat quote before any work starts, so there’s no surprise at the end.
Is blown in insulation worth it in Upland’s heat?
Yes. Upland attics regularly pass 140°F in summer, and even a few inches of added blown-in coverage changes how much heat transfers into living space. The payback shows up first as rooms that hold temperature better and AC that cycles less.
Can you blow insulation over old material in Upland?
In most Upland homes it’s fine, as long as the existing material is dry and hasn’t been damaged by rodents or roof leaks. We inspect the attic first and tell you if removal is necessary before we add anything. Call (855) 382-3925 for a free estimate.

What Upland 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
