Why Hollywood Insulation Co Is Highland’s Preferred Spray Foam Insulation Company

We’re not a general contractor who dabbles in insulation. We do one thing: install insulation properly, using the right method and the right material for the home in front of us. That focus shows in the work we’ve completed throughout Highland, from the older citrus-era bungalows near Baseline to the 1970s tract homes off Victoria Avenue and the newer foothill subdivisions climbing toward the San Bernardino Mountains. Homeowners in Highland call us because we carry eight manufacturer brands, including Icynene and Demilec spray foam systems, so the recommendation is always method-agnostic. We don’t push what’s on the truck; we specify what the house actually needs.

Our crews know Highland’s housing stock intimately. The 1950s through 1980s wood-frame tract homes that dominate 92346 have predictable failure points: collapsed original batts, unsealed top plates, recessed can lights acting as thermal chimneys, and rim joists that leak conditioned air into the attic. That’s the work we do week after week here. When you call Hollywood Insulation Co, you get a dedicated insulation specialist who can diagnose the actual problem, not a sales rep guessing from a brochure.

Every project is led with direct accountability to Noel Camacho, who oversees our Highland jobs and makes sure each install meets the air-sealing and R-value standard the home needs. We carry both open-cell and closed-cell spray foam from Icynene and Demilec, and we’ll tell you honestly when spray foam is the right call, and when blown-in cellulose or Rockwool mineral wool would serve better. That’s what carrying eight brands and three installation methods means: the honest answer, not the convenient one.

Rim Joist Spray Foam in Highland

Rim joist spray foam in Highland is one of the highest-return air-sealing jobs we do, because the rim joist is where conditioned interior air escapes into the unconditioned attic space above the exterior walls. In Highland’s 1950s through 1980s tract homes, the rim joist cavities were rarely sealed or insulated at all. Open-cell spray foam fills those tight, awkward bays completely, stopping the stack effect that pulls cooled air out of the living space and drags 150°F attic air down through wall cavities. A typical rim joist spray foam job in Highland runs $1,200 to $2,400, depending on linear footage and access.

The difference after sealing rim joists is immediate: rooms that held heat all afternoon finally stabilize, and the AC stops fighting a losing battle against attic air infiltration. This is one of the first things we check on any Highland home where owners complain about upstairs bedrooms running 8 to 12 degrees hotter than the rest of the house.

Sealing the Thermal Boundary

The rim joist is the top edge of your foundation wall, where the floor framing meets the exterior wall. In a Highland summer, that junction becomes a direct conduit between the superheated attic and the conditioned rooms below. Sealing it with closed-cell spray foam creates a continuous thermal boundary at the point where your home is most vulnerable to air exchange.

Dust Control Along the Foothill Edge

For homes on Highland’s east side, near the base of the foothills, rim joist sealing does double duty. Those gaps that leak air also pull in fine dust kicked up by Santa Ana winds and foothill gusts. Sealing them with spray foam reduces both the heat load and the amount of grit that ends up inside the house during windy weeks.

Crawl Space Spray Foam Insulation in Highland

Crawl space spray foam insulation in Highland addresses the other major thermal weakness in 92346 homes: the floor system above a ventilated crawl space. Most older Highland tract homes built in the 1950s through 1970s have unconditioned crawl spaces with fiberglass batts stuffed between floor joists, and those batts have typically sagged, collected dust, and stopped doing their job years ago. Spraying closed-cell foam directly against the underside of the subfloor and sealing the rim joist from below locks the floor system tight. Typical crawl space spray foam floor insulation in Highland runs $3,500 to $7,000, depending on square footage, access clearance, and whether old batts need removal first.

The benefit shows up fastest in rooms above the crawl space, which in Highland’s wood-frame homes are often the living room and kitchen. Homeowners report floors that no longer feel warm to the touch during late-afternoon heat, and cooling bills that drop because the envelope finally closes at the bottom of the house.

Removing Collapsed Batts Before Foam Application

One of the most common mistakes we see in Highland crawl spaces is spray foam applied over old fiberglass batts that were left in place. The foam adheres to the dusty surface of the batt, not to framing, and within a season it delaminates and falls. We remove old batts before spraying so the foam bonds directly to the subfloor and joists, which is the only way to get a durable, continuous air seal.

Crawl Space Floor Comfort

Highland’s low-pitched homes with open crawl vents let hot outdoor air circulate under the floor all summer. Sealing the crawl space floor system with spray foam stops that convection loop and makes the first floor feel like the rest of the house, not five degrees warmer by 4 PM.

Trusted Brands We Service in Highland

We install spray foam systems from Icynene and Demilec, two of the most specified spray polyurethane foam brands in North America, along with fiberglass from CertainTeed, mineral wool from Rockwool, and recycled cellulose from GreenFiber. For Highland homeowners, that means we can match the chemistry and density to the specific job. Open-cell Icynene works well for interior air-sealing in attics where you want moisture permeability. Closed-cell Demilec brings the higher R-value per inch needed on rim joists and crawl space applications. We keep local stock available for fast turnarounds on Highland jobs, so we’re not waiting on a distributor in Riverside or Ontario when your project is scheduled.

Common Spray Foam Insulation Problems We See in Highland Homes

• Foam applied over collapsed R-11 batts without removal. We find this constantly in Highland’s 1950s and 1960s tract homes. The foam sticks to the dusty old batt surface, not to framing, and delaminates within a season, leaving gaps that let attic heat pour back in.
• Unsealed can lights left in place before foaming. In Highland homes with recessed lighting, those fixtures are thermal chimneys. If they’re not sealed and protected before spray foam goes in, hot spots form around each can, the foam degrades from direct heat exposure, and the attic keeps leaking heat into the rooms below.
• Incorrect mix ratio on high-heat days. Spray foam mixed off-ratio during a 100°F-plus Highland summer afternoon develops poor cell structure and can off-gas. This is a real problem in foothill attics where installers try to work through the peak heat instead of scheduling around it. We monitor substrate temperatures and adjust our install windows to avoid the hottest hours.
• Ignoring rim joists and top plates while foaming the roof deck. A roof deck spray job that skips the rim joist and top plate sealing only solves part of the problem in a Highland tract home. The attic stays cooler, but the stack effect through the walls keeps pulling conditioned air out of the living space all day long.
