Why Hollywood Insulation Co Is Jurupa Valley’s Preferred Spray Foam Insulation Company
Homeowners across the 91752 area call us because we do one thing: insulation. Not HVAC, not windows, not general contracting. Just insulation. That focus means our technicians diagnose thermal bypasses and air leaks the way a mechanic listens for a bad bearing. It’s second nature because it’s all we do.
We install Spray Foam Insulation systems from Icynene and Demilec, two of the most specified spray polyurethane foam brands in North America. That matters because foam chemistry differs, and the wrong open-cell or closed-cell call in a dusty Mira Loma outbuilding can mean delamination down the road. We specify for the substrate, not for whatever’s on the truck.
Response time to Jurupa Valley is usually next-day for estimates, and we schedule most spray foam installs within the week. Noel Camacho runs every project with a simple rule: give the homeowner the right insulation for their home’s actual needs, not the easiest one to sell.
Spray Foam Insulation Contractors in Jurupa Valley
Spray Foam Insulation Contractors in Jurupa Valley do more than hook up a rig and start spraying. The job here means testing substrate moisture and dust levels, checking the attic’s venting configuration, and deciding whether open-cell or closed-cell foam actually fits the application. In older Mira Loma ranch homes, that substrate check is the difference between foam that bonds for 20 years and foam that pulls away in five.
A full attic spray foam job in Jurupa Valley typically runs $2,200 to $4,800 for open-cell and $3,500 to $6,500 for closed-cell on a standard 1,200 to 1,800 square foot attic. Rim joist work lands lower, usually $900 to $1,800. Detached outbuildings and tack rooms on horse properties fall somewhere in the $1,500 to $3,200 range depending on size and whether we’re spraying walls, ceilings, or both.
Open-Cell vs. Closed-Cell in Jurupa Valley’s Climate
Open-cell foam (we spray Icynene) is an air-sealing workhorse. It stops dry, dusty air from sneaking through your attic floor into the living space. Closed-cell (Icynene and Demilec) adds a moisture and vapor barrier and roughly doubles the R-value per inch. In Jurupa Valley, the low humidity means open-cell is usually the right call for vented attics, while closed-cell earns its cost on unvented roof decks and outbuildings where you need structural rigidity plus heat blocking.
Rim Joist Spray Foam for Older Ranches
Homes built in the 1960s and 70s across Jurupa Valley often have completely uninsulated rim joists. That’s a direct path for hot, dusty air to enter the wall cavities in summer. Spraying the rim joist with closed-cell foam costs between $900 and $1,800 and pays back quickly when your AC stops running 14 hours a day in August.
Spray Foam Attic Insulation in Jurupa Valley
Spray Foam Attic Insulation in Jurupa Valley has to handle the hottest part of the house. Attic temperatures here routinely spike past 140°F, and that’s not an exaggeration. The foam’s job is to keep that heat from radiating down through the ceiling. In most Jurupa Valley homes, that means spraying the attic floor or the roof deck depending on whether the attic is vented or conditioned.
For a vented attic, we typically air-seal and spray 5 to 6 inches of open-cell on the attic floor, which runs $2,200 to $4,200 for a standard ranch home. For an unvented roof deck, we spray closed-cell directly to the underside of the sheathing, usually 2 to 3 inches, which lands between $3,500 and $5,800. Garage ceiling spray foam and roof deck work fall within those same ranges depending on square footage and access.
The Substrate Problem Nobody Talks About
In Jurupa Valley’s Mira Loma flats, years of dry, dusty air leave a fine coating of dust on attic wood framing. Foam won’t bond to that. We abrasive-blast and prime older outbuilding and ranch attic substrates before spraying, a step many crews skip until the foam starts peeling. We’d rather spend an extra hour prepping than redo the job in three years.
Spray Foam Roof Deck in the 91752
New infill construction in the 91752 often has under-insulated roof decks because builders meet minimum code and stop. We regularly spray closed-cell foam to the roof deck in those homes to bring the attic inside the conditioned envelope. That eliminates the radiant heat problem entirely and drops upstairs bedroom temps noticeably the same season it’s installed.
Trusted Brands We Service in Jurupa Valley
We carry spray foam systems from Icynene and Demilec, and we stock the related materials needed for Jurupa Valley jobs: primer for dusty substrates, the right spray tips for hot-weather application, and backup equipment so a pump failure doesn’t leave you with a half-sprayed attic for a week. Our broader material bench includes CertainTeed and GreenFiber for homeowners comparing foam against blown-in or batt options. If foam isn’t the right answer for your home, we’ll tell you that and install what is. No forcing a method because it’s what we push.
Common Spray Foam Insulation Problems We See in Jurupa Valley Homes
- Foam delamination from dusty substrates. We see this constantly in older Mira Loma outbuildings and ranch attics where decades of dry, dusty air coated the framing. The foam itself was fine; it just never bonded properly. We abrasive-blast and prime before spraying every time now.
- Shrinkage and gapping in 1970s-era spray foam. Early-generation foam installed during the Nixon administration wasn’t built for 140°F heat cycling. It off-gasses, shrinks, and leaves gaps that bleed conditioned air. Removal and re-spray is the fix.
- Too-thin foam on new infill construction. Builders in the 91752 area often spray the minimum thickness to pass inspection. It does nothing to stop radiant heat gain. We go thicker where the roof deck takes full afternoon sun.
- Uninsulated detached shops and tack rooms. Horse properties in the Mira Loma flats have outbuildings that were never insulated at all. Those spaces hit 120°F inside by noon in summer. Spray foam on the walls and ceiling changes that completely.

FAQs About Spray Foam Insulation in Jurupa Valley
The pull-away almost always traces back to dust. Jurupa Valley’s dry, dusty air settles on attic framing over years, and foam cannot bond to a dusty surface. We abrasive-blast and prime old substrates before spraying, which prevents the delamination problem entirely. If your existing foam is peeling, it was likely sprayed on unprepped wood. Call (866) 605-6949 and we’ll inspect it for free.
No. The old batts have to come out first. In most 1960s-70s ranches around Jurupa Valley, those original batts have sagged and compacted to half their rated R-value anyway, so they’re doing almost nothing. We remove the degraded material, inspect and sometimes blast the substrate, then spray fresh foam. You get a clean start with full adhesion.
It outperforms fiberglass in two ways that matter here. First, spray foam air-seals, which fiberglass does not. That stops dry, dusty air from infiltrating your living space. Second, closed-cell foam adds a radiant heat block at the roof deck, which fiberglass batts on an attic floor simply cannot match. In a climate where attic temps hit 140°F, that difference is measurable on your first summer bill.
Yes, and it’s one of the highest-impact upgrades we do out there. Those outbuildings were never insulated, and they turn into ovens by midday. Spraying 2 inches of closed-cell foam on the walls and ceiling typically drops interior temps 12 to 18 degrees during a hot afternoon. We were called to a 1968 ranch in the Mira Loma flats where the original fiberglass batts had sagged to half their R-value and a detached tack room was completely uninsulated. After removing the degraded batts, we sprayed 2 inches of closed-cell foam (Icynene) to the attic deck and walls of the tack room, sealing the dry, dusty infiltration paths that had been cooking the space. The homeowner reported the tack room stayed 15°F cooler during a 105°F afternoon, and the main attic no longer radiated heat into the living room.
For a vented attic, 5 to 6 inches of open-cell foam meets code and handles Jurupa Valley’s heat load when combined with proper air sealing. For an unvented roof deck, 2 to 3 inches of closed-cell foam puts you in good shape. Builders often spray thinner to cut costs, then homeowners fight a hot second story every summer. Don’t accept the minimum. Call (866) 605-6949 for a free thickness assessment on any new-build or existing attic in Jurupa Valley.
