We know this town’s housing. Mentone sits right where the valley gives way to the San Bernardino foothills, and the homes here tell that story: mid-century ranches off Mentone Boulevard, older cabins tucked onto acreage, detached workshops with roll-up doors, and plenty of low-pitch roofs that make insulation work a tight squeeze. We plan for that before we ever pull up the truck.

Why Hollywood Insulation Co Is Mentone’s Preferred Spray Foam Insulation Company
We’re an insulation specialist, not a general contractor who picked up a foam rig last year. Every technician on our crew works in this one trade, diagnosing air leakage, thermal bypasses, and R-value deficiencies day in and day out. For Mentone homeowners, that matters because the problems here are specific: settled fiberglass in low-pitch attics, blocked soffit vents hidden behind stored boxes, rim joists that were never sealed when the cabin was built.
Our Spray Foam Insulation team carries eight manufacturer brands across every major insulation category. For Mentone, that means we match the foam system to your actual roof pitch, framing, and heat profile, rather than pushing whatever’s on the truck. We install Icynene open-cell for interior wall cavities where you want both air sealing and some sound control, and Demilec closed-cell where you need maximum R-value per inch, like tight attic retrofits or rim joist bands.
We serve Mentone with same-week scheduling in most cases. Noel Camacho, who runs our company, keeps our crews routed through the Inland Empire consistently, so a Mentone job doesn’t wait behind a Hollywood project. If you’re up off Wabash Avenue or out toward the wash, we’ll still get there without charging a travel fee.
Spray Foam Wall Insulation in Mentone
Spray Foam Wall Insulation in Mentone involves injecting or applying expanding foam into exterior wall cavities to create a continuous air barrier and a high-R-value thermal layer. Older Mentone homes rarely have adequate wall insulation, and the dry heat here turns under-insulated walls into radiant panels that bake rooms well past the thermostat setting. A typical wall foam job here runs $2,800 to $7,400, with open-cell systems like Icynene landing on the lower end for accessible stud cavities and closed-cell Demilec on the higher end where you need more R-value in less space.
When Mid-Century Ranches Need Wall Foam
The ranch homes that line Highway 38 and the streets off Mentone Boulevard were mostly built before modern energy codes. We regularly open these walls and find nothing but a thin layer of R-11 batts that has slumped or been chewed through by rodents. Foam fills the cavity completely, adheres to the framing, and stops the hot air that pushes through every stud gap when the afternoon sun hits the west and south walls.
Detached Workshops and Accessory Buildings
Plenty of Mentone properties have a detached shop, garage, or converted outbuilding that was never insulated at all. Foam on those walls makes a difference you’ll feel the first time you walk in during August. We can spray the walls, the rim joists, and the roof deck on a workshop in one visit, usually the same day.
Rim Joist Spray Foam in Mentone
Rim Joist Spray Foam seals the band board where your floor framing meets the foundation, a spot that is almost never insulated in older Mentone construction. That unsealed rim lets hot attic air and dusty crawlspace air into the house, and it also gives rodents a highway through your walls. A rim joist job in Mentone typically costs $900 to $2,200 depending on the lineal footage and how accessible the joist bays are. We use closed-cell Demilec for most rim joists because it adds structural rigidity and blocks moisture migration from the soil.
Why Rim Joists Fail in Older Cabins
The original cabins scattered around Mentone were often built on pier-and-beam foundations with the rim joists left completely open. Decades of heat and dry air have shrunk the framing, widening the gaps. Foam expands into those irregular spaces and locks the air leaks shut in one pass.
The Connection Between Rim Joists and Attic Heat
When your attic hits 140°F in July and the rim joists are open, that heated air moves down the wall cavities and into the living space. Foaming the rim joists cuts that cycle off at the source, which lets wall insulation and attic insulation do their jobs instead of fighting a convection loop.
Trusted Brands We Service in Mentone
We stock and install Icynene and Demilec spray foam systems in Mentone because they are the two most specified spray polyurethane foam brands in North America, and they cover the full open-cell and closed-cell range. We also carry CertainTeed and GreenFiber for clients who want a hybrid approach, like closed-cell foam on the roof deck with GreenFiber blown over the attic floor. Because we work with eight manufacturers total, we are not tied to a single product line and we won’t talk you into a system that doesn’t fit your roof pitch or your budget.
Common Spray Foam Insulation Problems We See in Mentone Homes
- Foam over settled original insulation. In low-pitch Mentone attics, we often find original fiberglass or rock wool batts that have compressed to half their rated R-value. Spraying foam over that without addressing the venting just traps heat against the ceiling and makes the problem worse.
- Blocked venting from later remodeling. Homeowners add storage platforms, walls, or finish a section of attic and accidentally seal off the soffit vents. Foam is an air barrier, so if the venting is still blocked after we spray, the attic turns into an oven. We check this before we ever load the gun.
- Unsealed rim joists in older cabins. The pier-and-beam cabins in Mentone almost always have open rim joist bays. Hot air migrates from the attic down the walls, so foam on the walls alone won’t solve the heat problem until the rim is sealed too.
- Incorrect foam thickness on mid-century ranch walls. We see handyman-applied foam kits that left the walls at half the R-value Mentone’s summer heat demands. A 2×4 wall with closed-cell foam needs the full cavity depth to actually stop radiant heat, and thin applications fail when the temperature climbs past 100°F.
Pricing for Spray Foam Insulation in Mentone, CA
Wall spray foam in Mentone runs $2,800 to $7,400 for a typical single-story home. Rim joist work runs $900 to $2,200. Garage ceiling or roof deck foam runs $1,800 to $4,900. The biggest cost variables are square footage, roof pitch for attic access, and whether we’re spraying open-cell or closed-cell. Closed-cell Demilec costs more per board foot but delivers roughly twice the R-value per inch, which matters in tight Mentone attics where there isn’t room for thick insulation. We give free estimates, we quote a fixed price before the truck shows up, and we do not tack on surprise fees. Call (866) 605-6949 for a number.

FAQs About Spray Foam Insulation in Mentone
Yes, but only if the venting is cleared first. In older Mentone cabins with low-pitch roofs, we check the soffit and ridge vents before any foam goes in, because spraying an air barrier over a blocked vent turns the attic into a heat trap. We clear the venting, then foam the roof deck or the ceiling plane depending on your layout. Call (866) 605-6949 and we’ll assess your cabin’s specific venting situation before recommending anything.
Spray foam stops heat at the roof deck rather than trying to slow it at the ceiling. In Mentone attics where the original insulation has settled to half its rated value, closed-cell foam on the underside of the roof deck creates a conditioned attic that blocks radiant heat before it ever reaches the living space. That is the key difference from just adding more fiberglass on top of settled batts.
Yes. We regularly foam detached workshops and garage areas on Mentone acreage properties, including the walls around oversized roll-up door openings. The door opening itself is the biggest air leak in any shop, and foaming the surrounding walls and rim joists is the highest-impact step you can take. We’ll do the walls, the rim joist, and the ceiling in one trip so you don’t have to take another day off work.
Closed-cell Demilec is usually the right call for flat-roof Mentone ranches with minimal attic clearance. It delivers R-6.5 to R-7 per inch, which means a 2×8 roof bay gives you roughly R-45 in the space where fiberglass would give you R-19. That matters when the sun pounds a flat roof all afternoon in July. Call us for a roof inspection and we’ll tell you exactly what your framing can support.
Yes, and it is one of the most cost-effective fixes we do here. Rim joist spray foam in Mentone runs $900 to $2,200, and the payback comes in the form of fewer hot spots, lower cooling costs, and fewer pests. We use closed-cell foam on rim joists because it blocks both air and moisture migration from the crawlspace. Call (866) 605-6949 for a rim joist estimate and we’ll check your whole band board while we’re there.
One-Trip Mentone Spray Foam, Planned Around Your Property
Mentone homes rarely fit the standard template. They’re ranch houses with added wings, cabins with low roof pitches, or properties with a detached shop that has an oversized roll-up door and its own set of problems. We recently foamed the rim joists and walls of a mid-century ranch off Mentone Boulevard where the homeowner had added a detached workshop. The original attic insulation was thin and settled, the low roof pitch made access tight, and the shop’s roll-up door opening leaked air like a screen. We used Icynene spray foam on the rim joists and walls, sealed the air leaks, and finished without a second trip.
That’s how we work in Mentone. We bring the right foam system for the roof pitch, the framing, and the heat load, and we plan the job so it gets done in one visit. If you’re tired of hot rooms, high summer bills, or a workshop you can’t use after noon, call (866) 605-6949 for a free estimate.
