Insulation Company in Upland, CA
Blown in insulation solves the most common problem we see in Upland homes: attic cavities that were under-insulated in the 1960s and have only gotten worse as the original batts settled flat. In a climate where summer attic temperatures routinely pass 130°F, that thin layer of compressed fiberglass means your air conditioner works overtime and upstairs rooms never quite cool down. Most Upland ranch and tract homes from the 1950s through 1970s have R-11 to R-19 in the attic when today’s building science calls for R-38 or better. We bring the attic up to where it should be with loose fill insulation that fills every joist bay completely, and we do it without tearing out your drywall. Call us at (866) 464-1714 for a free estimate on bringing your Upland attic up to current standards.
Why Upland Homes Are Different
Upland sits right where the Inland Empire meets the San Gabriel Mountains, and that location shapes every insulation job we do here. The 91784 foothill ZIPs back up against the mountains and take the full force of afternoon sun and Santa Ana winds, so homes up there run hotter and leakier than houses just a few miles south. We routinely find attic temps above 130°F in the foothill neighborhoods during July and August, which tells you two things: the attic needs more insulation, and it also needs a radiant barrier or at minimum cleared, functioning ventilation before that insulation can do its job. The older ranch homes in 91785 and 91786 were built when energy was cheap and insulation was an afterthought. Many of them still have the original low-density batts, now settled, compressed, or blown around by decades of wind working through the vents. Newer subdivisions in 91784 have taller rooflines and vaulted ceilings that make coverage uneven if the installer doesn’t know where the thermal boundary actually sits. Add in the fact that foothill attics collect wind-blown dust, dry leaves, and wildfire ash in their vents and soffits, and you have a situation where insulation alone won’t fix anything until the airflow is sorted out first. That’s the Upland difference: this is a radiant heat and air sealing problem, not just an R-value number.
Our Main Upland Services
Upland homeowners call us most about two things: attic insulation that’s finally stopped working and spray foam for hard-to-reach or unusually shaped spaces. Here’s what each one looks like in Upland specifically.
Attic Insulation in Upland
Most Upland homes from the 1950s through 1970s still carry original attic batts that have settled to a fraction of their rated R-value. Add the radiant heat load from the San Gabriel foothills and you get bedrooms that never cool down in summer, even with the AC running all day. We pull out or top up that old material, air seal the attic floor, and install new insulation matched to the home’s actual roofline and venting. In the 91784 foothill areas with vaulted ceilings, that often means working around complex framing that a standard batt installer would leave under-covered. Read our full breakdown here: Attic Insulation in Upland.
Spray Foam Insulation in Upland
Spray foam earns its cost in Upland when a home has odd cavity shapes, exposed rim joists, or vaulted ceilings where batts leave gaps. The foothill subdivisions in 91784 have complex rooflines that make continuous coverage difficult with any batt product, and the Santa Ana wind season pushes drafts through rim joists and band boards that spray foam seals completely. We install both open-cell and closed-cell foam, selecting the product by the application rather than by what’s on the truck. Read our full breakdown here: Spray Foam Insulation in Upland.

Blown In Insulation in Upland
Blown in insulation is the fastest, least disruptive way to bring an older Upland attic up to a useful R-value, and it’s the right call for most ranch homes built between the 1950s and 1970s that still have thin, settled originals. In Upland’s long, dry, 95-100°F summers, cooling dominates the energy load, and an attic with R-38 of loose fill insulation stops the radiant heat above from soaking through your ceilings and forcing the AC to run longer. Older homes in 91785 and 91786 with original batt insulation are perfect candidates because the material we blow in settles into every joist bay, fills gaps the batts left open, and creates a continuous thermal blanket no rolled product can match. We offer Blown In Insulation in several material types, including cellulose and fiberglass, and we’ll recommend the one that fits your budget and performance goal.
Cellulose Insulation
Signs you need it
Your attic insulation looks like flat, dusty newspaper or you can see the joist tops clearly above the current material level.
What it costs in Upland
Blown-in cellulose in Upland typically ranges from $1.20 to $2.20 per square foot depending on depth and existing material removal.
How we do it
We remove or top the existing material, air seal the attic floor penetrations, then blow in recycled cellulose to the target depth using a calibrated machine that ensures even coverage.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic run 8-10°F warmer than the rest of the house in summer, or your AC runs constantly from June through September.
What it costs in Upland
Blown-in attic insulation in Upland ranges from $1,500 to $3,200 for a typical 1,200 to 1,800 square foot single-story home.
How we do it
We confirm venting is clear, air seal the attic floor, set depth markers, and blow insulation to the specified R-value, then verify coverage with a depth check in every quadrant.
Blown In Cellulose Insulation
Signs you need it
You want insulation with high recycled content, or your current attic material has compressed so much it no longer meets the original spec.
What it costs in Upland
Blown-in cellulose with air sealing in Upland generally lands between $1,700 and $3,500 for comprehensive attic retrofit work.
How we do it
We prep the attic, seal bypasses around can lights and top plates, blow cellulose to R-38 or higher, and leave a signed coverage map showing depths in each zone.
Blown In Fiberglass Insulation
Signs you need it
Your attic has uneven patches of old fiberglass, or you want a non-cellulose loose fill option with decent thermal performance per inch.
What it costs in Upland
Blown-in fiberglass in Upland typically runs $1.30 to $2.50 per square foot for standard attic re-insulation.
How we do it
We remove old or compromised material as needed, verify the attic is ready for loose fill, and blow fiberglass to the target depth using Upland’s current Title 24 recommendations for attic R-value.
Loose Fill Insulation
Signs you need it
You have odd attic geometries, shallow joist bays, or areas where batts leave continuous gaps that show as warm stripes on your ceiling.
What it costs in Upland
Loose fill insulation projects in Upland generally fall between $1.20 and $2.50 per square foot plus any removal and air sealing work.
How we do it
We choose the loose fill material that fits your specific attic depth and venting configuration, then blow it to uniform coverage so no joist bay is left shallow.

Is blown in insulation worth it in Upland’s heat?
Yes. Attic temperatures above 130°F push heat through your ceiling all afternoon in Upland’s summer, and raising attic insulation from R-11 to R-38 cuts that heat gain enough to show up on your July and August electric bills. Call (866) 464-1714 for an exact quote.
How long does blown in insulation take in Upland?
One day for most Upland ranch homes. We typically start around 8am, finish before 4pm, and clean the work area before we leave. Call (866) 464-1714 to schedule a date.

Prices in Upland shift with a few local realities. Foothill homes in 91784 with vaulted ceilings and complex rooflines take longer and cost more per square foot than flat-attic ranch homes in 91786. Attics that haven’t been cleaned in years and need vent clearing, baffle resetting, or full material removal also add to the total, as does any air sealing work on older 1950s framing. We quote upfront and the price we quote is the price you pay, with no surprise add-ons at the end of the job.
