We’re familiar with the subdivisions along FM 1518 and FM 3009, the vented attics in Fairhaven and Belmont Park, and the specific failure pattern that hits Schertz homes built between 1998 and 2015: blown fiberglass that settled from its original R-30 to an effective R-20 or below, usually without anyone noticing through multiple military-family turnovers. That’s not a guess. We’ve pulled enough attic hatches in Schertz to know what the builder-grade insulation from the 2000s looks like after fifteen Texas summers.

Why Topside Attic Insulation Schertz Is Schertz’s Preferred Blown-In Insulation Company

We’ve sealed and insulated more than 9,000 homes since 2016, and a significant share of that work has been in the Schertz market - particularly the production-builder subdivisions that went up during the I-35 corridor boom. Our crews know the difference between a DR Horton attic from 2008 and a Lennar attic from 2012, and we know where the air leaks tend to cluster in each.

Schertz customers have left us detailed reviews mentioning specific outcomes: lower summer electric bills, upstairs rooms that finally hold temperature, and documentation they could hand to the next buyer. We don’t ask for ratings; we ask homeowners to check their blower-door numbers and their August bills.

Response time to Schertz runs 48-72 hours for standard appointments, with same-day availability for urgent cases like post-storm damage or failed insulation removal. Calls are answered by a live person 24/7, not a callback queue.

Our local knowledge extends to the specific code and climate pressures on Schertz housing: the 140-155°F attic temperatures from June through August, the hard-freeze risk that Winter Storm Uri proved in February 2021, and the fact that most Schertz homes were never air-sealed at the top plates or can lights during original construction. We correct that before we add insulation. Always.

Our Blown-In Insulation Services in Schertz

Blown-In Cellulose

We use GreenFiber cellulose for most Schertz attic top-ups because it performs well in the extreme heat of South Central Texas attics and settles less than fiberglass over time. Cellulose also provides better resistance to air movement, which matters in Schertz homes where the original builder never sealed the top plates. A typical Schertz single-story home runs $2,800-$4,200 for a full cellulose top-up to R-38 after air sealing. We blow it dense, not fluffy, so the R-value you pay for is the R-value that remains.

Blown-In Fiberglass

When the original insulation is fiberglass and the homeowner wants to match materials, or when moisture management is the primary concern, we blow Owens Corning fiberglass to the specified depth. In Schertz, we see this most often in newer subdivisions like Ashley Place where the original blown fiberglass is still in reasonable condition but has settled unevenly. A targeted fiberglass top-up runs $1,800-$3,200 depending on attic square footage and access. We mark the depth sticks in multiple locations so you can verify the coverage yourself.

Dense-Pack Wall Insulation

Schertz’s wood-frame tract homes rarely have insulated wall cavities from the builder, and the 2×4 construction limits what we can achieve. Dense-pack cellulose or fiberglass, blown at 3.5 pounds per cubic foot to eliminate settling and air gaps, typically reaches R-13 to R-15 in existing walls. This is not a common service in Schertz - most of the energy loss is through the attic - but for homes with finished bonus rooms over garages or additions with exposed walls, dense-pack runs $3.50-$5.50 per square foot of wall area. We scope every cavity with a borescope before we quote.

Blown-In Top-Up

This is our most frequent service call in Schertz, and for good reason. The city’s housing stock - almost entirely built between 1998 and 2015 - was insulated to minimum code with blown fiberglass that has now settled well below its labeled R-value. A blown-in top-up in Schertz is almost never about adding insulation to a bare attic. It’s about correcting settled, air-leak-riddled builder-grade fiberglass from the 2000s-2015 DR Horton and Lennar boom along the I-35/Randolph corridor.

We start with a visual assessment and, on request, a blower-door test to quantify the air leakage. Then we seal every top plate, can light, and penetration we can access before we add material. The top-up itself runs $2,400-$4,800 for most Schertz homes, and we provide before-and-after blower-door numbers on every job where the test is performed so you can see the performance change in a single figure.

In Fairhaven, a two-story slab home built in 2006, we pulled the attic hatch on a house whose owner had just PCS’d in and couldn’t get the second floor below 80°F - the original blown fiberglass had settled to roughly 4 inches across the center bay, reading an effective R-20 or less against the builder’s R-30 spec. We air-sealed the top plates and can lights, then blew GreenFiber cellulose to bring the flat ceiling back up over R-38, and the client called back after the next August billing cycle to say the upstairs unit finally cycled like it should.

Trusted Brands We Service in Schertz

We source blown-in materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, with no proprietary product lock-in. For Schertz customers, this means we select the right material for the specific failure pattern in your attic, not the one with the highest margin. GreenFiber cellulose is our default for settled fiberglass replacement in Schertz’s vented attics because it handles the 150°F summer cavity temperatures without the thermal drift we see in older fiberglass. We stock common depths and densities locally, so most jobs don’t wait on material delivery. If your home has existing Icynene or Demilec spray foam that needs repair or extension before a blown-in top-up, we can coordinate that work without a second contractor.

Common Blown-In Insulation Problems We See in Schertz Homes

• Settled blown fiberglass in subdivisions off FM 1518 and FM 3009. The mid-2000s production rush left thousands of Schertz homes with blown fiberglass that has settled unevenly, leaving bare drywall patches at the center of each bay where the R-value collapses well below the original R-30. Military renters and short-tenure owners rarely commission energy audits, so these degraded assemblies go undetected until a $400 summer electric bill finally prompts a call.
• Unsealed top plates and can lights pulling superheated attic air into conditioned space. Original builder-grade bath fans, can lights, and top plates were never air-sealed in Schertz’s tract homes, so attics pull 140-155°F air and dust into the conditioned envelope and flatten the insulation’s effective performance. The insulation can’t do its job if the air moves through it.
• Heat-degraded facings and crusted loose fill. Attic cavities hitting 150°F during June through August accelerate the breakdown of older kraft and poly facings and cause the loose fill to crust and lose loft, so a nominal R-30 assembly behaves closer to R-20 by the time a homeowner is staring at a $400 summer bill. This is a South Central Texas specific failure mode you don’t see in cooler climates.
• Insufficient insulation for hard-freeze protection after Winter Storm Uri. The February 2021 freeze burst pipes in poorly insulated homes across the Schertz area, and builder-grade R-30 in the attic wasn’t enough to protect ceiling cavities and exterior walls when temperatures held below 15°F for multiple days. A proper top-up to R-38 or R-49, combined with air sealing, provides the thermal buffer that minimum-code insulation never could.
