We’ve worked in enough Schertz attics to know the pattern. The production-builder tract homes that went up from the late 1990s through the 2010s, the ones filling subdivisions off FM 3009 and Schertz Parkway, were insulated to pass inspection, not to perform. After 15-25 years of attic temperatures hitting 150-160°F, that original blown fiberglass or cellulose has settled, shifted, and degraded. The AC runs nonstop. The upstairs never cools. The homeowner replaces the compressor and wonders why nothing changed. We open the hatch, measure depth, and find R-18 where there should be R-30 or better. That’s the Schertz attic story we see weekly.

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

We’ve sealed and insulated 9,000+ homes since 2016, and a growing share of that work is in Schertz’s 2000s-era subdivisions. Our Attic Insulation in Schertz crews know the difference between a DR Horton attic and a Lennar attic, the quirks of production-builder HVAC routing, and where the insulation gaps show up after a decade of military renters near Randolph AFB.

Our reviews from Schertz customers consistently cite two things: the written price they received before anyone touched the attic, and the documented photo record and blower-door numbers they walked away with. Under Haven Standard: Have it in writing. No exceptions.

Response time to Schertz is same-day for most calls placed before noon. Dispatch coordinates from our San Antonio office, but the crew that shows up at your door knows Schertz, knows the tract-home layouts, and carries Owens Corning, Johns Manville, and Knauf materials on the truck.

Our Attic Insulation Services in Schertz

Blown-In Attic Insulation

Blown-in fiberglass or cellulose is the standard fix for settled production-builder insulation in Schertz. We blow Owens Corning or Johns Manville fiberglass to R-38 or R-49, depending on your roof geometry and energy goals. In Woodland Oaks and The Crossvine, where original R-30 has compressed to R-18, blown-in top-up is usually the most cost-effective path. We never blow over an unsealed attic floor. Our Attic Insulation team seals top plates, can lights, and penetrations first, then blows. The blower-door test before and after shows the difference in CFM50.

Attic Batt Insulation

Batt insulation, the pre-cut fiberglass or mineral wool panels, makes sense in Schertz homes with specific access constraints or where we’re insulating knee walls, storage platforms, or dropped soffits that blown material can’t fill evenly. We source Knauf batts for these applications and cut to fit around trusses and HVAC platforms without compression gaps. Compression kills R-value. We photograph every bay before we close it.

Attic Insulation Top-Up

This is our most common Schertz service. The attic has existing insulation, but it’s thin, patchy, or settled. We measure depth at multiple points, calculate the gap between current effective R-value and target, and blow precisely that amount. Most Schertz top-ups run $900-$2,200 and take a single day. The Crossvine homeowner we mentioned earlier, the one whose house wouldn’t hold below 80°F, got a Blown-In Insulation - Schertz top-up. We added R-20 of blown fiberglass over the settled original, installed baffles to keep soffit vents clear, and the system stopped fighting itself.

Attic Insulation Replacement

Full replacement means removal of existing material, air sealing of the deck, and new insulation to spec. We recommend this in Schertz when the original insulation has been contaminated by rodent activity, water damage from roof leaks, or when multiple military-tenant turnovers have left it walked flat around HVAC platforms. Replacement runs $1,800-$4,500 in Schertz depending on attic square footage and whether we’re treating a single-story or two-story layout. Every replacement job gets a written scope, written warranty, and documented photo record before we leave.

Attic Baffles & Ventilation Prep

Schertz’s 150-160°F attic temperatures make ventilation critical. Baffles, also called vent chutes or rafter vents, keep soffit intake air flowing over the insulation rather than getting blocked by it. In production-builder homes where insulation was blown to the eaves without baffles, the soffits are often choked. We install proper baffles as part of any top-up or replacement, ensuring the attic breathes. This matters more in Schertz than in cooler climates. A sealed, well-insulated attic with dead ventilation cooks the shingles and traps moisture.

Common Attic Insulation Problems We See in Schertz Homes

• Settled blown insulation in 2000s tract homes. The original R-30 fiberglass or cellulose in Woodland Oaks, The Crossvine, and Schertz Parkway subdivisions has settled to an effective R-18 or lower after two decades of thermal cycling. We confirm this by measuring depth at the attic hatch and multiple interior points.
• Compression and displacement from HVAC maintenance traffic. In Schertz’s high-turnover rental stock near Randolph AFB, technicians have walked on attic insulation for years to reach air handlers, compressing it to near-zero R-value in traffic paths. No owner-occupant was present to notice or correct it.
• Missing or inadequate pipe-adjacent insulation. The February 2021 freeze exposed a vulnerability in Schertz homes insulated to hot-climate minimums. Pipes in unconditioned attics and exterior walls lacked the coverage needed for hard freeze events. We address this during replacement jobs by insulating pipe runs to a higher standard than original construction.
• Blocked soffit ventilation. Production builders often blew insulation deep into eaves without installing baffles, choking off intake airflow. The attic overheats, shingles degrade faster, and cooling load spikes. We find this in roughly half the Schertz attics we open.
