Fast, Reliable Spray Foam Insulation Across Beverly Hills
Spray foam insulation in Beverly Hills typically costs $2.50 to $6.50 per square foot for closed-cell and $1.50 to $3.50 for open-cell, depending on whether we’re air-sealing a roof deck, a garage ceiling, or rim joists. Most Beverly Hills homeowners call us for one specific reason: their mid-century home bakes in summer because the original attic insulation has failed and the flat roof radiates heat straight into the living space. We know those houses, because we work on them every week. If you’re feeling that afternoon heat buildup in a 90210 ranch or a 90212 Mediterranean rebuild, call (866) 271-1602 and we’ll assess your roof deck and attic sealing the same week.
Why Fontana Insulation Is Beverly Hills’s Preferred Spray Foam Insulation Company
Fontana Insulation is the material-agnostic insulation specialist for Beverly Hills. We don’t stock one foam brand and push it on every roof. We carry Icynene and Demilec spray foam products, and our recommendation comes down to what your specific attic or wall assembly actually needs. Noel Arredondo built our team around a simple rule: match the material to the house, not the inventory to the sale.
Beverly Hills homeowners regularly tell us they’ve had contractors tell them fiberglass is fine, or that spray foam is overkill, or that they should just blow more cellulose on top of the old stuff. Those are stock answers. A 1950s ranch off Lomitas Avenue with original R-7 batts and leaky flex duct isn’t the same job as a new contemporary rebuild in the flats. We send our Beverly Hills crew out familiar with the housing stock, the permit reality of Title 24, and the specific failure points those older attics share.
Because we install spray foam, blown-in, and attic insulation in-house, the person who diagnoses your thermal boundary is the same crew that fixes it. That matters more in Beverly Hills than almost anywhere: this is a design-driven, detail-driven market, and our Beverly Hills customers expect a foam application that changes the house’s comfort without changing its appearance.
Garage Spray Foam Insulation in Beverly Hills
Garage Spray Foam Insulation in Beverly Hills is most commonly requested for garages that sit under bedrooms or have become workshops, home gyms, or wine storage. The job involves air-sealing the garage ceiling and rim joists from the attic side, or applying foam directly to the garage’s shared walls with living space. In Beverly Hills, we see this called for in mid-century homes where the garage was never conditioned and the attic hatch opens into a superheated air cavity.
Typical garage ceiling spray foam in Beverly Hills runs $1,800 to $4,200 depending on square footage and whether we’re addressing shared walls, a bonus room, or just the garage ceiling itself. That range usually includes removal of old batts, foam application, and re-insulating the hatch.
Rim Joist Sealing
Older Beverly Hills garages leak air where the floor framing meets the foundation wall. We spray the rim joists from inside the garage or the crawl space, creating an air seal that blocks the hot, dusty Santa Ana air from pushing into the house. In a 1960s Beverly Hills garage, rim joist sealing is often the single highest-impact fix for rooms above the garage.
Garage Ceiling Air-Sealing
If the garage sits below living space, the ceiling is the thermal boundary. We spray the garage ceiling cavity from the attic side and foam the gap around any recessed fixtures or plumbing penetrations. The result is a garage that stays dramatically cooler in summer without adding heat load to the bedroom above.
Closed Cell Spray Foam Insulation in Beverly Hills
Closed Cell Spray Foam Insulation in Beverly Hills is the spec we recommend most often for roof decks on the low-pitch and flat-roof homes built throughout the 90210 and 90212 grid. Closed-cell foam seals, insulates, and acts as a radiant barrier against the intense summer sun that beats down on flat roof membranes. In Beverly Hills, that combination is what changes a hot, unconditioned attic into a semi-conditioned, stable space.
Closed-cell spray foam in Beverly Hills typically runs $3.75 to $6.50 per board foot applied, though the more useful number is the project total. A standard mid-century ranch roof deck with 4 to 6 inches of closed-cell runs $9,000 to $16,000 before any Title 24 scope adjustments.
Roof Deck Application
We apply closed-cell directly to the underside of the roof deck, creating an unvented assembly. This is the right call for Beverly Hills homes where the ductwork lives in the attic and the roof is too low-pitch for conventional venting to work well.
Duct Boot Sealing
On the same house, we foam the boots and return boxes where ducts meet the ceiling. In a mid-century Beverly Hills home with original flex duct, this single step stops attic air from mixing with conditioned air, which is often the hidden reason the living room never drops below 78 in July.
Trusted Brands We Service in Beverly Hills
Fontana Insulation installs spray foam from Icynene and Demilec, two of the most performance-tested foam brands in North America. We carry Icynene because it provides consistent closed-cell performance for roof decks and rim joists, and Demilec because its open-cell and closed-cell lines handle the detailed air-sealing jobs we see in Beverly Hills attics and garages. For Beverly Hills homeowners whose priorities sit elsewhere, we also install Rockwool mineral wool for fire resistance and sound dampening, plus CertainTeed fiberglass for budget-driven blow-in replacements. Our Beverly Hills crew keeps common stock on hand, so a typical spray foam job gets scheduled without waiting on a distributor to ship materials across town.
Common Spray Foam Insulation Problems We See in Beverly Hills Homes
- Original R-7 to R-11 attic batts that have collapsed: Most 1950s and 1960s Beverly Hills homes still have their original attic insulation. It’s compressed, dusty, and leaving the roof assembly wide open to heat transfer. Replacing it with spray foam at the deck is the most common fix, but the old batts have to come out first, because foam over failed batts locks in the dust and gaps.
- Leaky flex duct in unconditioned attics: The same era of housing put ductwork in the attic. In Beverly Hills, that attic hits 130 degrees in summer, and the ducts leak cold air straight into it. If we don’t address duct sealing alongside the foam, the homeowner pays for insulation twice and still has hot rooms.
- Moisture trapped in vented assemblies that got sealed incorrectly: Closing a low-pitch 1950s-60s roof deck with spray foam without addressing the original vented attic design can trap moisture in a Mediterranean-climate assembly that was never meant to be sealed. It requires a site assessment and usually a moisture mitigation plan before the foam goes in.
- Overspray and dust drift during application: Beverly Hills homeowners rightfully expect the work to stay in the attic. In tight mid-century chases and around recessed lighting, sloppy closed-cell application causes overspray on finished surfaces and dust drifting into living rooms. We run full containment before we open the hatch.

FAQs About Spray Foam Insulation in Beverly Hills
Yes, and in most cases it’s the right material. Because much of the 90210/90212 grid is low-pitch or flat roof with original R-7 to R-11 attic insulation, spray foam here is mostly specified as an air-seal and radiant-barrier layer at the roof deck rather than as a thick cold-climate R-value stack. On a mid-century ranch off Lomitas Avenue in 90210, we found the original R-7 attic batts sagging over leaky flex duct in an unconditioned, low-pitch attic. We removed the collapsed batts and applied closed-cell spray foam to the roof deck and duct boots, sealing the assembly and cutting the summer heat baking through the flat roof. The homeowner’s only requirement: zero debris drifting into the living room, so we ran full containment before we opened the attic hatch. Call (866) 271-1602 and we’ll assess your specific roof pitch and attic condition.
No. Spray foam should not be applied over collapsed or compressed original batts, because the old material still blocks the foam from sealing the deck and holds decades of dust against the new foam. We remove the failed batts, inspect the duct boots and top plates, seal those gaps, and then apply the foam. In Beverly Hills, skipping the removal step is the most common cause of a “foamed” attic that still gets hot.
It shouldn’t. We run full containment before opening the attic hatch in Beverly Hills homes, especially the tighter mid-century chases where dust drift is most likely. That means plastic barriers, negative air, and a clean path from the entry to the attic access. If you’ve heard stories of overspray on furniture or dust in the living room, that’s what happens when a crew skips containment. We don’t.
If the garage sits under living space or you use it as a workshop, gym, or storage for heat-sensitive items, yes. We spray the garage ceiling and rim joists, seal the hatch, and often add a small amount of closed-cell to the shared wall with the house. A typical Beverly Hills garage retrofit runs $1,800 to $4,200 and changes the garage from a heat sink to a usable space. Call (866) 271-1602 for a specific quote; we’ll walk the garage and tell you exactly what’s worth doing.
We install Icynene and Demilec spray foam products, both of which are among the most performance-tested brands in North America. For Beverly Hills homes where fire resistance or sound dampening is as important as thermal performance, we also install Rockwool mineral wool. Our recommendation changes with the house, not the other way around. If you’re comparing quotes, ask any other contractor which brands they carry and whether they stock Rockwool or both open and closed cell foam. Most don’t.
