Fast, Reliable Spray Foam Insulation Across Upland
Spray foam insulation in Upland typically costs $3,100 to $7,900 for a full attic application, with most crews finishing in one to two days. We run crews into Upland every week, so we know the difference between a 1920s bungalow off Euclid and a 1980s tract home above Foothill. If your upstairs rooms bake by 3 p.m. in August and your AC can’t keep up, the fix is usually in the attic. Call us at (866) 605-6949 and we’ll walk you through what your home actually needs.
Why Hollywood Insulation Co Is Upland’s Preferred Spray Foam Insulation Company
Upland homeowners call us because we’re a dedicated insulation contractor, not a generalist who happens to carry a foam rig. Every technician on our crew works in this one trade every day. Diagnosing thermal bypasses, air leakage, and R-value deficiencies in attics is what we do. Homeowners in the 91786, 91784, and 91785 ZIP codes trust us because we match the insulation method to the house, not to whatever material is already loaded on the truck.
We carry eight manufacturer brands across fiberglass, mineral wool, spray foam, and cellulose. That breadth matters in Upland specifically. A pre-war bungalow near the historic downtown core needs a completely different assembly than a mid-century rancher up toward San Antonio Heights. When we recommend Icynene open-cell foam for one attic and Demilec closed-cell for another, it’s because each one fits that specific structure. Our team is led by Noel Camacho, and he’s built Hollywood Insulation Co around one principle: the right insulation for your home’s actual needs, not a one-size-fits-all pitch. We respond to Upland service calls fast, usually same-week for estimates and often within 48 hours for scheduled work.
Spray Foam Insulation Contractors in Upland
Spray Foam Insulation Contractors in Upland handle the full scope of foam installation: air-sealing top plates and penetrations, prepping the substrate, applying open-cell or closed-cell foam to the correct depth, and verifying the finished R-value. Upland homeowners call contractors like us when rooms won’t hold temperature, when utility bills spike in July through September, or when an old attic has degraded insulation that’s settled to next to nothing. A typical spray foam job in Upland runs $3,100 to $7,900 for a full attic, depending on square footage, foam type, and whether the roof deck or the ceiling line gets the application.
Air-Sealing Before Foam Application
Foam sprayed over dust-compacted insulation or dirty framing won’t bond properly. In Upland’s older homes, especially around the 91786 core, we often find decades of settled dust and debris on attic surfaces. Our crews prep and air-seal before any foam goes down, so the air barrier actually works.
Open-Cell and Closed-Cell Choice
Open-cell foam like Icynene expands aggressively and seals irregular 1920s and 1930s framing well. Closed-cell Demilec adds structural rigidity and a vapor barrier, which matters for roof deck applications in older Upland homes with no existing vent path. We install both and recommend based on the attic’s actual condition.
Spray Foam Attic Insulation in Upland
Spray Foam Attic Insulation in Upland addresses the single biggest source of heat gain in foothill homes: the attic. On a 100°F Upland afternoon, an unventilated attic can hit 140°F or more. That heat radiates down through the ceiling and forces your AC to run constantly. Spray foam attic insulation in Upland typically costs $3,100 to $6,800 for a standard single-story home, though larger or more complex attics run higher. In the citrus-era bungalows near Euclid Avenue and Foothill Boulevard, spray foam is frequently the only viable air barrier and vapor control method once you seal an unvented assembly that never had soffit ventilation in the first place.
Roof Deck Foam for Ventless Attics
Pre-war Upland homes often have no soffit vents at all. Without a vent path, open-cell foam on the ceiling line can trap moisture. Closed-cell foam on the roof deck creates a sealed, conditioned attic assembly that works with the structure as it was built. This is a condition we see far more in 91786 than in the newer tracts up in 91784.
Ceiling Line Foam for Newer Homes
1970s and 1980s tract homes in Upland typically have at least some soffit venting. In those attics, open-cell foam applied to the ceiling line can seal the living space and leave the attic vented. It’s a less expensive path that still eliminates the radiant heat problem during Upland’s long hot summers.
Trusted Brands We Service in Upland
We work with Icynene and Demilec spray foam systems, two of the most specified spray polyurethane foam brands in North America. For Upland homeowners who want an eco-forward alternative, we also carry GreenFiber recycled cellulose and Owens Corning fiberglass. The point is fit. Your attic dictates the material, and we stock the breadth to actually choose well. Upland customers get the same brand access as our Los Angeles clients, without a special-order wait. Eight trusted brands, one honest recommendation.
Common Spray Foam Insulation Problems We See in Upland Homes
- Foam over legacy insulation. In the 1920s-40s bungalows near the historic downtown, previous owners sometimes had foam sprayed directly over settled, dust-compacted insulation without air-sealing first. The foam fails to bond and traps dust, creating a mess that has to be fully removed and redone.
- Sealing an attic with no vent path. Upland’s pre-code homes in 91786 often have zero soffit ventilation. If open-cell foam goes on the ceiling line without addressing the assembly, moisture gets trapped. Closed-cell on the roof deck is the correct fix for those structures.
- Ignition concerns near the wildland edge. Homes above 91784 sit close to the wildland urban interface. Santa Ana wind-driven ember exposure means spray foam applications need ignition-resistant detailing and proper drywall or coating separation. We factor that in on every foothill project.
- Heat gain through undersized framing bays. Older Upland attics often have shallow or irregular framing depths. A generic R-value pitch won’t work. The foam depth and type have to match what the structure can actually hold, which is why we inspect before we quote.

FAQs About Spray Foam Insulation in Upland
We install Icynene and Demilec spray foam systems in Upland. Both are industry-leading brands, and we choose between them based on your attic’s specifics. Open-cell Icynene works well for ceiling-line applications in vented attics, while closed-cell Demilec handles roof deck assemblies in Upland’s ventless pre-war homes. We also carry GreenFiber and Owens Corning for homeowners who want blown-in or batt alternatives. Call (866) 605-6949 and we’ll recommend the right one for your house.
We typically schedule estimates in Upland within three to five business days, and installation often starts within one to two weeks depending on material and crew availability. For urgent heat-gain problems in July or August, we do our best to prioritize Upland calls. Call (866) 605-6949 and ask about current scheduling.
Yes. We work throughout Upland ZIP codes 91784, 91785, and 91786. That includes the historic downtown core around Euclid Avenue, the foothill-adjacent neighborhoods north toward San Antonio Heights, and the tract home areas south of Foothill Boulevard. We know the housing stock changes block by block here, and our recommendations reflect that.
Upland pricing runs about the same range as Claremont, Montclair, and Rancho Cucamonga: $3,100 to $7,900 for a full attic. What changes the cost in Upland specifically is substrate condition. The older bungalows in 91786 often need air-sealing and prep before foam, which adds labor. A 1970s tract home in 91784 typically needs less prep and lands at the lower end of the range.
Homes built before modern code often have no vent path, and spray foam is frequently the only way to create a proper air barrier and vapor control. We apply closed-cell foam to the roof deck to create a sealed, conditioned attic assembly. This approach works with the structure as it was built, which is why our Upland inspections always start with a vent assessment.
