We’ve been driving out to Schertz from our San Antonio dispatch office since we opened under The Haven Standard in 2016. We know the subdivisions - Woodland Oaks, The Crossvine, the Schertz Parkway corridor - and we know what we’ll find when we pull the attic hatch on a 2005 DR Horton or Lennar build. The cellulose has settled. The top plates leak. The HVAC plenum sits in a 155°F attic fighting a battle it can’t win. Our Spray Foam Insulation team treats every Schertz job as a building-envelope repair, not just a product installation. We seal first, then insulate, and we publish the blower-door numbers so you can see the difference.

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

We’ve sealed and insulated more than 9,000 homes since 2016, and a significant share of those have been in the I-35 corridor northeast of San Antonio. Schertz homeowners find us because they read the three-star reviews as carefully as the five-star ones, and they notice that our customers mention specific numbers - “4,200 CFM50 down to 2,100” - rather than vague praise.

Response time matters in July, when your upstairs bonus room won’t hold setpoint. We dispatch crews to Schertz daily from our San Antonio office. Most estimates happen same-day or next-day. The 365-Day Done Right Promise applies here exactly as it does everywhere else: if it’s not right, we make it right, and you get that in writing before anyone starts.

Our local knowledge runs deeper than zip codes. We know that homes near Randolph Air Force Base turn over fast - military renters in, military renters out - and that insulation problems fester across multiple tenancies with no owner-occupant to catch them. We know that Schertz’s 2000s-era production homes were built to pass inspection, not to perform. And we know that February 2021 proved how vulnerable slab-on-grade tract homes with thin wall insulation can be when a hard freeze hits.

Our Spray Foam Insulation Services in Schertz

Open-Cell Spray Foam

Open-cell spray foam is our most common recommendation for Schertz attic roof decks and exterior walls in conditioned-space conversions. At roughly half-pound density, it expands to fill irregular cavities in the truss bays of Woodland Oaks and Crossvine homes, and its vapor-permeable nature suits our hot-humid climate when paired with proper attic ventilation strategy. A typical open-cell job on a Schertz two-story roof deck runs $2.80-$3.80 per board foot. We source from Demilec and Johns Manville depending on the specific assembly and your written scope.

Closed-Cell Spray Foam

Closed-cell foam - two-pound density, vapor-retarding, structural-rigid - is what we use where Schertz’s climate demands a harder barrier: rim joists in crawl-less slab homes, exterior walls in garage conversions, and any assembly where February 2021-style freeze penetration is a documented risk. It’s more expensive, typically $4.20-$5.40 per board foot in this market, but it’s the right tool when condensation control matters as much as R-value.

Rim Joist Spray Foam

Schertz’s slab-on-grade production homes have a hidden leak point that blown attic insulation never touches: the rim joist, where the floor framing meets the foundation. In The Crossvine and Schertz Parkway subdivisions, we routinely find unsealed rim joists leaking conditioned air into the garage and pulling humid outdoor air into wall cavities. Our rim joist treatment uses closed-cell foam to seal and insulate this critical junction, typically $1,800-$3,200 for a full perimeter treatment depending on linear footage and access.

Garage Ceiling Spray Foam

Garage ceiling foam in Schertz serves two purposes: thermal separation from a hot garage in summer, and air-sealing where the house envelope is weakest. Many 2000s-era homes here have bonus rooms or bedrooms over the garage, and the original R-13 batt in the garage ceiling has compressed or fallen. We remove or work around the existing material, seal penetrations, and spray foam to create a continuous thermal boundary. Typical range: $2,200-$4,500.

Spray Foam Roof Deck

This is where we see the most dramatic performance change in Schertz. Converting a vented attic to a conditioned space by foaming the roof deck - the underside of the roof sheathing - drops the attic from 150°F+ to within 10-15°F of the living space. Your HVAC equipment stops fighting ambient heat it was never designed to handle. In Woodland Oaks we sprayed open-cell foam on a two-story brick-veneer home whose attic was hitting 155°F on a July afternoon, with the original cellulose settled so low we could see the ceiling joists at the hatch. Our tech measured only 6 inches of settled depth, sealed the top plates and recessed can housings, then foamed the roof deck to isolate the HVAC plenum from the 100°F attic. The homeowner reported the upstairs bonus room finally held setpoint past 4 p.m. Roof deck jobs in Schertz typically run $3,800-$7,200 for a complete treatment on a 2,000-2,800 square foot home.

Trusted Brands We Service in Schertz

We don’t lock you into proprietary products. Our materials come from Owens Corning, Johns Manville, Demilec, and other manufacturers we specify based on the assembly, not a distributor agreement. For Schertz’s hot-roof attic conversions, we typically specify Demilec open-cell formulations with compatible ignition barriers where code requires. For rim joist and exterior-wall work where vapor control is critical, we may recommend Johns Manville closed-cell systems. We stock common volumes locally for faster turnaround on approved jobs, and every product choice is documented in your written scope before work starts.

Common Spray Foam Insulation Problems We See in Schertz Homes

• Settled builder-grade cellulose creating false confidence. The original R-30 blown cellulose in 2000s Schertz tract homes has often compressed to an effective R-18 or worse after two decades of 150°F attic cycling. Homeowners think they have insulation; what they have is a thin thermal blanket with more air gaps than fiber.
• Military-renter turnover hiding deferred problems. Homes near Randolph AFB in The Crossvine and Schertz Parkway areas go through multiple tenancies with zero insulation oversight. We find disconnected flex ducts, crushed knee-wall batts, and even prior foam work done without proper substrate preparation.
• Attic hatches as the hottest leak point. Even when foam is sprayed correctly on roof decks or walls, an unsealed attic hatch in a Schertz hallway dumps conditioned air upward and pulls superheated attic air down. We treat the hatch as part of the assembly, not an afterthought.
• Freeze damage from improperly detailed rim joists. The February 2021 hard freeze cracked pipes and drywall in Schertz homes where foam had been applied to rim joists without a proper vapor retarder strategy. Closed-cell foam alone isn’t enough; the assembly has to be designed for our occasional extreme cold events, not just our normal heat.
