Why Hearthside Insulation Is Jurupa Valley’s Preferred Spray Foam Insulation Company
We’re an insulation-only contractor. That focus matters in Jurupa Valley, where most homes were built between 1950 and 1980 and need real air-sealing work, not just a layer of batts tossed over what’s already failing. Trevor Bassett and our crew work in this heat every week, and we understand how a 150°F attic behaves. We’ve air-sealed top plates in homes off Van Buren, in Pedley, and throughout the 91752 zip code. Homeowners in Jurupa Valley call us because we explain material tradeoffs in plain terms. You get both Icynene and Demilec spray foam options, which means we can honestly compare open-cell and closed-cell for your specific house instead of pushing whichever product we happen to have on the truck.
Our local reputation in Jurupa Valley is built on showing up when we say we will and doing the job the way we described it. We know the housing stock here: mid-century tract homes, some rural properties with original insulation, and newer infill builds. Each one needs a different approach. That’s the whole point of working with an insulation specialist rather than a general contractor running insulation as a side service.
Closed Cell Spray Foam Insulation in Jurupa Valley
Closed Cell Spray Foam Insulation is the choice we recommend most often for Jurupa Valley homes with unvented attics, roof decks, or rim joists that need a vapor barrier and serious structural strength. It cures dense and rigid, typically to about R-7 per inch, and it blocks both air and moisture. In a 1960s ranch off Van Buren Boulevard, closed-cell is often the only material that makes sense on the roofline, since it handles Jurupa Valley’s extreme temperature swings without breaking down or losing adhesion. Expect closed-cell spray foam in Jurupa Valley to run $1.50 – $3.50 per board foot for the material alone, with most full-attic installations landing between $5,000 and $12,000 depending on depth and access.
The real value of closed-cell here is what it does to old framing. It bonds to rafters and studs, stiffening the structure while sealing the gaps that let superheated attic air pour into living spaces. For Jurupa Valley attics that reach 140°F in August, closed-cell applied at the roofline keeps that heat out of the conditioned envelope entirely.
Rim Joist Applications
Rim joists in Jurupa Valley’s older homes are often completely uninsulated, which lets outside air circulate under floors and into wall cavities. We spray closed-cell foam at the rim joist to create an air and moisture seal that fiberglass can’t touch. This is one of the highest-value upgrades you can do on a 1950s – 70s tract home.
Open Cell Spray Foam in Jurupa Valley
Open Cell Spray Foam is our go-to for Jurupa Valley attics that are already vented and just need a high-performing thermal barrier that also seals air leaks. It expands to fill cavities better than any batt or blow-in product, typically performing around R-3.7 per inch. In Jurupa Valley, where original fiberglass batts in older homes have collapsed and stopped doing their job, open-cell applied across the attic floor gets you back to R-38 or better while closing the air bypass points that drive your cooling bill up. Expect open-cell spray foam in Jurupa Valley to run $1.00 – $2.50 per board foot, with a typical 1,500-square-foot attic landing between $3,500 and $7,000.
We carry both Icynene and Demilec open-cell systems. That matters because not all open-cell foam performs the same in desert heat. Some formulations hold up better under Jurupa Valley’s dry, high-temperature conditions, and having access to both lets us match the product to your attic’s ventilation setup rather than forcing one option.
Attic Floor Applications
For a vented attic, the floor is the right place for open-cell foam. We air-seal the top plates and baffles first, then spray across the attic floor to create a continuous thermal blanket. This is the setup that fixed the 1960s ranch off Van Buren Boulevard where 150°F air was pouring into the back bedrooms through an unsealed top plate.
Trusted Brands We Service in Jurupa Valley
Hearthside Insulation installs spray foam from Icynene and Demilec, two of the most respected manufacturers in the category. We also work with Owens Corning and Rockwool for fiberglass and mineral wool applications where those materials are the better fit. Having eight brands across four material types means we match the product to your Jurupa Valley home’s needs, not the other way around. We keep inventory staged for fast turnaround in the 91752 zip code, so once your estimate is approved, we can usually schedule within a week. For older Jurupa Valley homes needing both spray foam and supplemental mineral wool, one crew handles the whole job.
Common Spray Foam Insulation Problems We See in Jurupa Valley Homes
- Foam sprayed over unsealed top plates and missing baffles. In 1950s – 70s tract homes, original insulation often settled or was never installed properly. If spray foam goes down without air-sealing first, hot attic air bypasses the foam entirely and you still get uneven cooling.
- Closed-cell foam applied too thin on roof decks in unvented attics. We’ve seen attic upgrades in Jurupa Valley where a thin layer of closed-cell was sprayed directly on the roof deck. Under summer heat cycles, that thin layer doesn’t provide the R-value or moisture control needed, and condensation becomes a real problem.
- Open-cell foam in poorly ventilated attics. Open-cell is breathable by design. If it’s used in an attic with inadequate ventilation, moisture can accumulate inside the foam and degrade it over time. Jurupa Valley’s dry heat masks this problem for a while, then it shows up as a musty smell or reduced performance.
- Spray foam installed without addressing the existing degradation. Foam over collapsed fiberglass doesn’t fix the air leaks underneath. We remove the old batts and air-seal before spraying, because that’s the only way the foam actually delivers its rated performance in a 60-year-old Jurupa Valley house.
Pricing for Spray Foam Insulation in Jurupa Valley, CA
Open-cell spray foam in Jurupa Valley typically runs $1.00 – $2.50 per board foot for residential attics, while closed-cell runs $1.50 – $3.50 per board foot. A full attic air-seal and open-cell upgrade on a 1,500-square-foot home usually lands between $3,500 and $7,000. Closed-cell roofline installations on the same size home run $5,000 – $12,000 because of the higher material cost and the prep work involved. What affects your final number: how much old insulation needs removal, how accessible your attic is, whether top plates and baffles need sealing, and the depth of foam required for your target R-value. For a property in the 91752 zip code, we’ll give you an exact quote after a free on-site inspection. Call (877) 265-4871 and Trevor or one of our crew will walk you through it.

FAQs About Spray Foam Insulation in Jurupa Valley
Yes, but only when it’s installed correctly. Closed-cell spray foam, which we apply for roof decks and rim joists, is rated for continuous high-heat exposure and doesn’t soften or off-gas in Jurupa Valley’s attic conditions. Open-cell foam on an attic floor also holds up well in dry heat, but only if the attic is properly vented first. The key is heat-resistant formulation and proper substrate prep, which is exactly what we do on every job. Call (877) 265-4871 if you want us to check your attic’s temperature profile before you commit to a material.
Spray foam air-seals as it insulates, which fiberglass batts simply don’t do. In Jurupa Valley’s 1950s – 70s homes, the original fiberglass has usually collapsed or settled, and the top plates and baffles are leaking hot attic air directly into living spaces. Spray foam fills those gaps and bonds to the structure, creating a continuous thermal barrier that drops cooling bills by a measurable amount. For an older tract home off Van Buren Boulevard, this is the single highest-impact upgrade you can make besides replacing a failed AC unit.
In most cases, yes. Spraying foam over collapsed or degraded fiberglass doesn’t solve the air leaks underneath, and it can trap heat and moisture in ways that reduce the foam’s performance. We remove the old material, air-seal the top plates and baffles, then apply the foam. For a 60-year-old Jurupa Valley attic, skipping this step means paying for foam that never delivers its rated R-value. We’ll show you what’s up there during the free estimate so you can see for yourself.
Spray foam slows heat transfer in both directions. In summer, it keeps superheated attic air from radiating down into your living space, which means your AC runs less and your back bedrooms stop cooking. In winter, it traps the heat you pay for inside the house. For Jurupa Valley’s climate, where summer highs routinely exceed 100°F and winter nights can drop near freezing, spray foam delivers year-round benefit that fiberglass never quite matches.
Spray foam is safe around most wiring, but knob-and-tube is a different story. Spraying foam directly over active knob-and-tube wiring can cause the wires to overheat, because the foam acts as a thermal insulator around the wire. If your Jurupa Valley home still has knob-and-tube, we’ll identify it during the inspection and recommend either having an electrician address it first or choosing a different insulation approach for those cavities. We will not spray over active knob-and-tube. That’s a hard line, and it’s the same standard any responsible insulation contractor in Riverside County should follow.
