Attic Insulation in Schertz - Same-Day Service, Done Right the First Time

Fast, Reliable Attic Insulation Across Schertz

Most attic insulation jobs in Schertz run $1,800-$4,200 depending on attic size and whether we’re topping up existing material or starting fresh after removal. Our crews dispatch from the San Antonio office and typically arrive in Schertz within 45 minutes of the scheduled window. We’ve worked in the subdivisions off Schertz Parkway, the neighborhoods near Universal City Road, and the FM 1518 corridor long enough to know what builder-grade insulation from 1998 looks like after two decades of 150°F attic summers.

Why Topside Attic Insulation New Braunfels Is Schertz’s Preferred Attic Insulation Company

We’ve sealed and insulated over 9,000 homes since 2016, and a concentrated slice of that work has been right here in Schertz. The reviews that matter most to us are the ones from homeowners who checked our blower-door numbers against their energy bills three months later.

Our response time to Schertz averages under an hour because we keep crews routed through the I-35 corridor and FM 78. We don’t ask you to wait in a callback queue; a live person answers the phone 24/7.

What separates our work in Schertz is familiarity with the specific housing stock. These aren’t theoretical homes. We know the DR Horton and KB Home floor plans from the 2000s building boom. We know which subdivisions got R-30 batts and which got blown fiberglass that was already settling before the original owners hung their curtains. That local knowledge means we walk your attic already knowing where the top plates typically leak and where the can lights were installed without boxes.

Our Attic Insulation Services in Schertz

Blown-In Attic Insulation

Blown-in fiberglass or cellulose is what most Schertz attics need, especially the 1990s-2010s tract homes built during the Randolph corridor expansion. We use Owens Corning and Johns Manville loose-fill products, blown to a uniform depth with density-checked coverage. In Schertz’s vented attics, blown-in settles into the irregular joist bays better than batts and fills the gaps around wiring and top plates that air sealing exposed. A typical full-coverage blown-in job in Schertz runs $2,400-$3,800 for attics between 1,200 and 2,400 square feet.

Attic Batt Insulation

Batt insulation still has a place in Schertz, particularly in new additions, garage attic spaces, and areas where we need precise R-value per inch in a confined cavity. We stock Knauf and Rockwool batts for Schertz jobs where the homeowner wants the density and fire resistance of mineral wool, or where we’re matching existing batt systems during a partial replacement. Batt work in Schertz typically costs $1,800-$2,800 for accessible attics under 1,500 square feet.

Attic Insulation Top-Up

This is our most common call in Schertz. The thermal mass of Schertz’s 1990s-2010s slab-on-grade tract homes means the attic bakes all day and then radiates heat down through the ceiling drywall well into the night, so the envelope fails as a slow overnight heat gain rather than a quick daytime spike. Many homes near the Universal City Road and FM 1518 corridors sat untouched for a decade-plus of PCS cycles, which is why blower-door testing often finds 1998-vintage blown fiberglass compressed to an effective R-15 in an attic spec’d at R-30. We don’t blow new insulation over that compressed layer without first air-sealing the ceiling plane. A top-up with air sealing in Schertz typically runs $1,800-$3,200.

Attic Insulation Replacement

When the existing insulation is contaminated, water-damaged, or degraded past recovery, we remove it entirely. In Schertz, we see this most often after roof leaks, rodent activity in the attic, or when the kraft facing on older batts has cooked to brittleness in 150°F attic heat. Full removal, disposal, air sealing, and re-insulation in Schertz runs $3,200-$5,400 depending on attic square footage and contamination level. Every replacement job includes our Documented Photo Record and, where applicable, before-and-after blower-door readings.

Attic Baffles & Ventilation Prep

Schertz’s low- to mid-pitch roofs, common in the Savannah subdivision and along Schertz Parkway, create tight soffit-to-ridge channels that clog easily with blown insulation. We install Owens Corning rafter baffles at every soffit intake to maintain the ventilation path. Without baffles, your attic ventilation stalls, moisture accumulates, and the insulation you just paid for underperforms. Baffle installation is typically $400-$800 as a standalone service, or included in our full attic packages.

Common Attic Insulation Problems We See in Schertz Homes

• Builder-grade blown fiberglass in these vented attics settles and compresses, losing R-value fastest at the eaves and around recessed lights, so the perimeter rooms run hottest. On a call off FM 1518 near the Randolph corridor, our crew found a 1999 DR Horton build with the original blown fiberglass settled to roughly half its installed depth and a ceiling hatch so warped it leaked attic air into the hallway. We air-sealed the top plates and hatch, added Owens Corning blown-in over the existing fiberglass to restore a uniform R-30-plus blanket, and installed baffles at the soffits to keep the intake path clear. After the top-up, the homeowner reported the front bedrooms no longer hit 80°F by mid-afternoon.
• Attic temps over 150°F day after day cook the kraft facing on older batts until it turns brittle and delaminates, leaving bare fiberglass that slumps and no longer blocks radiant gain. Schertz’s position in the transition zone between humid Gulf Coast air and drier Hill Country air means that heat gain is compounded by moisture cycling, accelerating the breakdown of batt facings faster than in purely arid climates.
• Post-2021 freeze awareness revealed that many 1990s-2010s Schertz homes have no continuous air barrier at the ceiling plane, so humid Gulf air migrates into the attic and degrades insulation performance long before it looks physically damaged. The 2021 Winter Storm Uri exposed pipe-freeze and wall-cavity gaps that had gone unnoticed for decades, triggering a second wave of insulation audits among Schertz homeowners who suddenly understood their envelope was leaking in both directions.
• Military families cycling through JBSA-Randolph on 2-to-3-year PCS orders have historically deferred insulation upgrades as renters or short-term owners, meaning many Schertz homes in the Universal City Road and FM 1518 corridors near the base have never had their original builder insulation touched. A local technician doing a blower-door test here will routinely find 1998-vintage blown fiberglass sitting at an effective R-15 in an attic rated R-30 on the builder’s spec sheet.
