We’re an insulation-only contractor, which matters in a city where the housing stock demands specialized retrofitting rather than new-construction installs. The 1950s stucco ranches that dominate Lakewood present a specific set of challenges: bare stud bays, slab foundations, and attic spaces that trap summer heat. Someone who splits time between plumbing and insulation won’t know what to do with a bare 1950s wall cavity. We do.
Why Ruby Insulation Is Lakewood’s Preferred Spray Foam Insulation Company
Lakewood homeowners call us because we understand the difference between insulating a new build and retrofitting a 70-year-old Lakewood Park tract home. Most of our Lakewood work happens in original 1950s single-story ranches on slabs, where the wall cavities were often left empty when the homes went up. That’s not a repair job; it’s a retrofit project that requires injection ports, stucco patching, and careful attention to air-sealing details most contractors miss.
Noel Ibarra leads our crews, and his approach is straightforward: diagnose the actual problem before recommending a product. We carry open-cell and closed-cell spray foam from Icynene and Demilec because those systems hold up in the specific conditions Lakewood homes present, but we’ll tell you honestly if blown-in fiberglass or mineral wool makes more sense for a particular attic. We serve all four Lakewood ZIP codes, 90711 through 90714, and our familiarity with the original tract layouts means we’re not figuring out your home’s construction on the fly.
When you call, you get a specialist who’s seen hundreds of Lakewood attics and wall cavities. We schedule estimates quickly, show up when we say we will, and keep the work area clean. Our crews patch stucco carefully after wall injections because we know the street face of a Lakewood ranch is part of its curb appeal. That level of local care is why homeowners in 90712 and 90713 keep referring us to neighbors.
Spray Foam Attic Insulation in Lakewood
Spray Foam Attic Insulation in Lakewood is most often a retrofit job aimed at the flat or low-slope attic spaces above original 1950s ranch homes, where summer heat gain pushes upstairs and back bedrooms well past comfortable temperatures. The work involves sealing top plates, duct penetrations, and any gaps where the 1950s framing meets the stucco, then applying foam to the roof deck or attic floor depending on whether the attic is vented or unvented. A typical Lakewood attic retrofit runs $4,500 to $10,800 depending on square footage and foam type.
Vented attics and floor applications
Many Lakewood attics still use the original vented design with fiberglass batts on the attic floor. We can remove or supplement that insulation and spray foam directly against the attic floor, sealing the air leaks that let conditioned air escape from the living space below.
Unvented attic conversions
When a Lakewood homeowner wants to use attic space for storage or needs to bring ducts inside the conditioned envelope, we convert the attic to an unvented assembly by spraying closed-cell foam against the underside of the roof deck. This is common in the 90712 tracts where homeowners have added attic access and want to stop the late-afternoon heat that radiates down through ceilings in August.
Spray Foam Wall Insulation in Lakewood
Spray Foam Wall Insulation in Lakewood is almost always a retrofit through existing stucco cladding, because the original Lakewood Park homes were built with bare 1950s stud bays and no sheathing cavity to blow into from outside. We drill small injection ports through the stucco at each stud bay, fill the cavity with open-cell foam, then patch and color-blend the ports. Expect to pay $3.50 to $6.80 per square foot of wall area for a full injection retrofit, with a typical 1,200-square-foot ranch running $8,000 to $14,000 for complete wall coverage.
Injection through original stucco
The process requires patience and precision. Overfilling a bay cracks 70-year-old stucco, which shows up as blisters on the street face. We fill bays to about 80 percent capacity and monitor each port as we go.

Top plate and rim sealing
Wall insulation alone underperforms if the top of the wall cavity remains open to the attic. In Lakewood’s slab-on-grade ranches, all air-sealing work happens from inside the attic or through the wall itself. We seal top plates and any duct penetrations as part of every wall foam job, because a bare top plate lets conditioned air escape straight into the attic.
Trusted Brands We Service in Lakewood
We carry Icynene and Demilec spray foam systems because those are the professional-grade products that make sense for Lakewood’s retrofit-heavy market. Both require trained, authorized installers to purchase and apply, which means the product accountability sits with us, not with a big-box store. For Lakewood attics where spray foam isn’t the right call, we stock Owens Corning and Johns Manville fiberglass as well as Rockwool mineral wool. Having multiple brands on hand means we can match the material to the specific house, rather than forcing one product into every 90712 or 90713 ranch we visit.
Common Spray Foam Insulation Problems We See in Lakewood Homes
- Bare 1950s stud bays behind original stucco. The Lakewood Park Company built these homes fast and skipped wall insulation entirely in many units. We still open up walls on 90712 and 90713 streets and find nothing but empty framing.
- Cracked or blistered stucco from previous injection attempts. Older foam injections done without proper technique left visible damage on the street face. We see these and know exactly what went wrong: too much foam, too fast, no monitoring.
- Attic heat gain overwhelming thin legacy insulation. Original attic insulation in Lakewood ranches was often a thin layer of fiberglass or nothing at all. By late afternoon in August, uninsulated ceilings radiate heat downward and rooms spike past 85°F.
- Missing top-plate and duct-penetration sealing. On slab homes with no crawlspace, the only place air can move is through the attic. If the top of the wall cavity stays open, even new insulation underperforms.

FAQs About Spray Foam Insulation in Lakewood
Yes, in most cases we inject open-cell foam through small ports drilled directly through the exterior stucco, which avoids any interior demolition. The ports are patched and color-blended afterward, and the process typically takes two to three days for a full house. Call (833) 356-0182 to schedule a wall inspection and find out if your stud bays are candidates for injection.
Most 90712 attics still hold original thin fiberglass that was inadequate when installed in the 1950s and has since settled and lost much of its R-value, plus the attic floor was never air-sealed so conditioned air escapes straight through gaps at the top plates and duct penetrations. Spray foam applied to the attic floor or roof deck seals those leaks and stops the heat transfer that makes back bedrooms spike. We can evaluate your attic and give you a specific recommendation.
Yes, spray foam is often the best fit for Lakewood slab ranches because there’s no crawlspace to insulate and the walls and attic are the only thermal envelope you have. Sealing the top plates and injecting the bare stud bays means the foam addresses both the insulation gap and the air leakage in one step. For 90712 and 90713 homes especially, this approach targets the exact failure points of the original construction.
We install Icynene and Demilec spray foam systems, both of which are professional-grade products only available through trained and authorized installers. The choice between them depends on whether open-cell or closed-cell foam fits the specific Lakewood home’s needs. Call (833) 356-0182 for a recommendation based on your actual wall and attic conditions.
It shouldn’t if the installer monitors fill pressure and doesn’t overfill the bays, because 1950s stucco is brittle and cracks when foam expands too aggressively. We fill bays to about 80 percent capacity and inspect each port visually as we work. This is why hiring a specialist who has done this exact retrofit on Lakewood Park homes matters more than finding the lowest bid.
