We’ve worked in Schertz long enough to know the difference between a 2004 DR Horton attic off FM 1518 and a 2015 Lennar build near Cibolo Creek. The housing stock here is remarkably consistent, and so are the problems: compressed batts, uncapped can lights, and radiant-barrier decking that’s stopped reflecting. That consistency means we can give you an accurate written scope faster, because we’ve already seen what’s likely up there.

Why Topside Attic Insulation Canyon Lake Is Schertz’s Preferred Spray Foam Insulation Company

We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in the Schertz corridor from Selma up through the Randolph-adjacent subdivisions. Our Spray Foam Insulation in Schertz customers leave reviews that specifically mention the blower-door numbers we publish, the photo records they received, and the fact that no one started spraying until they’d signed a written price.

Response time to Schertz averages under an hour from dispatch. We know the local permitting rhythm, the HOA notification requirements in communities like Kensington Ranch and The Crossvine, and the specific attic configurations that DR Horton and Lennar repeated across dozens of floor plans here. That local pattern recognition saves time on every job.

Our 365-Day Done Right Promise applies in Schertz exactly as it does everywhere else: if the foam doesn’t perform as scoped, we make it right. The Haven Standard requires a written warranty delivered before work starts, not after.

Our Spray Foam Insulation Services in Schertz

Open-Cell Spray Foam

Open-cell spray foam is our most common recommendation for Schertz’s vented production attics, and it’s the core of our Attic Insulation in Schertz. At roughly half-pound density, it expands to fill irregular cavities and provides both insulation and air-sealing in one pass. In Schertz’s 2000s-era homes with compressed fiberglass batts and bypasses at top plates, open-cell applied to the attic floor creates a continuous thermal and air barrier that the original builder-grade assembly never achieved. Most open-cell jobs in Schertz run $1.80-$2.40 per board foot installed.

The field vignette from Kensington Ranch off FM 1518 is typical: our crew opened a 2006 production-built attic and found compressed fiberglass batts plus eight uncapped recessed can lights dumping conditioned air straight into a 150°F attic. We air-sealed the top plates and can-light penetrations, then applied open-cell spray foam across the vented attic floor to stop the summer radiant heat load and the winter pipe-freeze exposure that showed up during Uri. The homeowner, a Randolph-family rental landlord, reported an immediate drop in cooling run-time.

Closed-Cell Spray Foam

Closed-cell spray foam, at 2-pound density and R-6.5 per inch, is what we use where moisture control or structural rigidity matters: rim joists in crawl spaces, garage ceiling undersides, and occasional roof deck applications where the homeowner wants conditioned attic space. In Schertz’s humid transition-zone climate, closed-cell’s vapor-barrier properties matter in basements and crawl spaces that see seasonal moisture. Closed-cell runs higher, typically $2.80-$3.50 per board foot in this market.

We don’t default to closed-cell in standard Schertz vented attics. The higher cost only makes sense when the application specifically demands its density or moisture resistance.

Rim Joist Spray Foam

Rim joist spray foam is one of the most overlooked upgrades in Schertz’s production-built homes. The rim joist, where the foundation wall meets the first floor, is often unsealed and uninsulated in 2000s builds, creating a thermal bypass that pulls conditioned air out and pulls garage fumes, pollen, and soil gas in. We see this constantly in Schertz homes with bonus rooms over garages or with attached garage configurations common in the DR Horton and Lennar plans.

Our Spray Foam Insulation crew treats rim joists with closed-cell foam after sealing all penetrations. The homeowner gets before-and-after photos and, where accessible, blower-door contribution readings showing the reduction in stack-effect leakage. Most Schertz rim-joist treatments run $800-$1,800 depending on linear footage and access conditions.

Garage Ceiling Spray Foam

Garage ceiling spray foam in Schertz addresses a specific pain point: bonus rooms and bedrooms over unconditioned garages that run 15-25 degrees off the rest of the house. The garage ceiling is typically a single layer of drywall with no air barrier and minimal insulation. We remove or work around any existing batts, air-seal penetrations for wiring and ducts, then apply open-cell foam to create a proper thermal boundary. This is a popular retrofit in Schertz’s rental market, where landlords need the bonus room to perform without rebuilding the HVAC zone.

Spray Foam Roof Deck

Spray foam applied directly to the roof deck converts a vented attic into conditioned space, moving the thermal boundary from the attic floor to the roofline. In Schertz’s extreme attic temperatures, this can be transformative for HVAC equipment and ductwork located in the attic. We only recommend roof-deck foam when the existing roof is in good condition and when the homeowner understands that the attic becomes part of the conditioned envelope, requiring proper dehumidification. Roof-deck jobs in Schertz typically start around $4,500 for a standard production home and scale with complexity.

Trusted Brands We Service in Schertz

We source materials from Owens Corning, Johns Manville, and Knauf for our Schertz jobs, along with other major manufacturers including Icynene and Demilec for specific spray foam formulations. We don’t lock you into proprietary products. Our San Antonio warehouse stocks common densities and application equipment, so most Schertz jobs don’t wait on material delivery. The brand selection for your specific job depends on the application, the existing conditions we find, and the performance target we set in the written scope. You’ll see the product specification in your contract before anyone starts.

Common Spray Foam Insulation Problems We See in Schertz Homes

• Compressed or settled builder-grade fiberglass batts in 2000s DR Horton and Lennar attics falling below rated R-value, so spray foam is applied over a failed baseline that must be removed or encapsulated first. We assess this during the initial inspection and specify removal or retention in the written scope.
• Uncapped recessed can lights in early-2000s Randolph-adjacent subdivisions leaking conditioned air into the attic, which superheats to 145-155°F and radiates back down. Foam alone won’t fix this. We cap and seal every can light before spraying, and we document it with photos.
• Radiant-barrier decking that degrades over time in these vented attics, and foam applied to a failing deck without addressing the degraded barrier traps heat rather than reflecting it. We inspect decking condition and specify replacement or treatment when needed.
• Top-plate bypasses at wall-to-attic transitions that were never sealed during original construction, creating continuous air leakage paths. Our blower-door test identifies these before foam goes in, and our crew seals them with targeted foam and caulk.
