Converse sits northeast of San Antonio with a housing stock shaped by decades of military-transient turnover around JBSA-Randolph. We’ve worked the streets west of Rocket Lane, the subdivisions along Farm-to-Market 1518, and the newer vinyl-sided developments near Converse North Park. That local familiarity matters because the insulation failures we find in a 1964 ranch off Gibbs Sprawl Road are completely different from what we see in a 2012 subdivision near Judson High School. Dispatch and scheduling run from our San Antonio office, but the crew that arrives at your door knows Converse construction.

Why Topside Attic Insulation Boerne Is Converse’s Preferred Spray Foam Insulation Company

We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our Bexar County retrofit work comes from Converse’s two distinct housing bands: the postwar and Cold War-era ranches near the Randolph perimeter, and the 2000s-2010s subdivisions built during the last growth wave. Converse homeowners tend to research thoroughly before calling - they read three-star reviews with the same attention they give five-star ones - so we publish before-and-after blower-door numbers on every applicable job. You see the pressurization reading, in CFM50, that documents exactly how much conditioned air your home was losing before we started and how much less it loses after we’re done.

Our response time to Converse averages same-day or next-day for standard calls, and our live-answer desk routes emergency requests immediately - no voicemail loops, no callback windows measured in business days. Every technician is background-checked and uniformed, and you get a text with their name when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician.

The 365-Day Done Right Promise applies to every completed job in Converse. If it’s not done right, we make it right. That promise is backed by a written scope and written warranty delivered before anyone lifts a tool, plus a Documented Photo Record included on every visit - not available on request, just delivered.

Our Spray Foam Insulation Services in Converse

Open-Cell Spray Foam

Open-cell spray foam runs roughly $1.80-$2.80 per board foot installed in Converse, making it the cost-effective choice for large attic envelopes and roof decks where thickness matters more than compressive strength. We specify open-cell for most Converse attic retrofits because it expands to fill irregular framing cavities in those 1950s-1970s ranch homes, many of which have non-standard joist spacing and low-pitch rooflines that make batt installation nearly impossible. The material is vapor-permeable, which matters in Climate Zone 2 - it allows attic moisture to dry toward the interior rather than trapping it against roof sheathing during Converse’s humid summer months. We source open-cell from Icynene and Demilec, and we pair it with targeted air sealing of top plates and can lights before the foam goes in.

Closed-Cell Spray Foam

Closed-cell runs $3.50-$5.50 per board foot in the Converse market, and we specify it where moisture control, structural rigidity, or limited space is the governing factor. Rim joists in Converse’s slab-on-grade ranches are a primary application - the material’s 2.0+ lb density and vapor-blocking properties stop ground moisture from wicking into the band joist, and its R-6.5 per inch lets us hit code in a 3-inch cavity where open-cell would need 5 inches. After Winter Storm Uri, we’ve also used closed-cell to insulate plumbing chases and water-line penetrations in unconditioned spaces, particularly in the 1950s-1970s ranches where original construction left pipes vulnerable. Closed-cell from Demilec and Owens Corning is stocked locally for Converse jobs, so we’re not waiting on freight.

Rim Joist Spray Foam

Rim joist spray foam in Converse typically costs $800-$1,800 for a standard slab ranch, depending on linear footage and whether we’re treating a full perimeter or just the worst zones. This is where we find some of the most severe thermal shortfalls in Converse homes: the intersection where the sill plate meets the foundation wall, often completely unsealed in original construction. In the base-adjacent ranches near JBSA-Randolph, decades of foundation settling have opened gaps that blower-door tests reveal as major leakage paths. We air-seal first, then foam the rim joist with closed-cell to create a continuous thermal and moisture barrier from slab to subfloor. On a recent job off FM 1518, the rim joist treatment alone dropped the blower-door reading by 380 CFM50.

Garage Ceiling Spray Foam

Garage ceiling spray foam in Converse runs $1,200-$2,600 for a typical two-car footprint, and it’s become a frequent request since Uri - homeowners who spent February 2021 in uninsulated garages with frozen water heaters don’t want to repeat the experience. We treat the garage ceiling as a conditioned-space boundary: seal all penetrations for electrical, plumbing, and HVAC runs, then foam the entire surface to create a thermal break between the garage and living space above. In Converse’s newer subdivisions, this also addresses the common builder practice of leaving garage ceilings as uninsulated open trusses with nothing but drywall between a 150°F attic and the master bedroom. Our Spray Foam Insulation team carries scissor lifts and spray rigs sized for residential garages, so we’re not improvising with equipment meant for commercial warehouses.

Trusted Brands We Service in Converse

We don’t lock customers into proprietary products. Our Converse crews stock and install materials from Icynene, Demilec, Owens Corning, and GreenFiber, selected job-by-job based on what the assembly actually needs. Icynene’s open-cell line is our default for large attic envelopes in Converse’s low-pitch ranches; Demilec’s closed-cell formulations go in where moisture drive or structural contribution matters; Owens Corning provides the rigid foam and radiant-barrier pairing we use on roof-deck assemblies in Climate Zone 2. Because we maintain local inventory, Converse customers aren’t waiting on cross-country freight when a specific foam kit or accessory is needed. We choose the material, explain why in the written scope, and install it - no brand upsells, no exclusivity claims we can’t document.

Common Spray Foam Insulation Problems We See in Converse Homes

• Base-adjacent attic crush. Contractors working the streets immediately west and south of JBSA-Randolph routinely find original 1960s fiberglass batts compressed to less than 2 inches, leaving those Converse attics at R-6 or below because decades of military-required annual HVAC inspections have crushed the insulation. That base-adjacent foot-traffic pattern is essentially absent in neighboring suburbs not tied to Randolph’s inspection cycle.
• Open-cell degradation on unvented low-pitch roofs. Attic temps above 150°F in Climate Zone 2 cause open-cell foam to off-gas and degrade faster if the attic isn’t vented or paired with a radiant barrier. This is acute on Converse’s low-pitch ranch roofs, where the original design assumed passive ventilation that has since been blocked by subsequent roofing layers.
• Uri-era freeze vulnerability in unconditioned spaces. The February 2021 Winter Storm Uri revealed severe under-insulation around water lines and in unconditioned spaces across Bexar County’s northeast suburbs. In Converse’s 1950s-1970s ranches, foam must extend into rim joists and plumbing chases or the retrofit repeats the freeze-risk pattern.
• Top-plate gaps defeating existing R-30. Converse’s 2000s-2010s vinyl-sided subdivisions on slab with R-30 blown fiberglass usually have top-plate and can-light gaps that defeat the existing insulation. Spray foam without air-sealing those penetrations underperforms - we see blower-door readings drop by half when sealing precedes foaming.
