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

Fast, Reliable Blown-In Insulation Across Schertz

Most blown-in insulation jobs in Schertz run $1,800-$4,200 depending on attic size and whether air sealing is needed first, and our crews typically schedule within 48 hours of your call. We dispatch from our San Antonio office and serve Schertz directly - including the subdivisions off FM 3009, Wiederstein Road, and the IH-35 corridors where the bulk of the city’s housing stock sits. If your upstairs bedrooms won’t cool below 78°F in July or your winter electric bills spiked after the 2021 freeze, the problem is usually builder-grade insulation that never met this climate to begin with.

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

We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our repeat calls come from Schertz’s post-2000 subdivisions - the same DR Horton, Lennar, and Centex tracts where R-30 attic minimums were standard and air sealing was treated as optional. Our Blown-In Insulation team knows these floor plans: the two-story layouts off Wiederstein Road with the master downstairs and kids’ rooms baking upstairs, the one-story ranch models near FM 3009 with scuttled attic hatches and no service platforms.

Reviews from Schertz customers consistently mention the blower-door numbers we publish - the before-and-after CFM50 readings that show exactly how much conditioned air stopped leaking after we sealed the top plates and can lights. Response time to Schertz is typically next-day or same-week; we don’t route crews through callback windows measured in business days. Calls are answered by a live person 24/7, and every technician is background-checked and uniformed.

What builds trust here is specificity. We can tell you which Schertz subdivisions used GreenFiber cellulose versus Owens Corning fiberglass batts, where the wind-washing at the eaves is worst, and why a home built in 2014 needs work sooner than one built in 1994 with better original craftsmanship. That local knowledge comes from documented records on every job, not from guesswork.

Our Blown-In Insulation Services in Schertz

Blown-In Cellulose

We install GreenFiber cellulose in Schertz attics at a settled density of 3.5 pounds per cubic foot, which gives us a true R-3.8 per inch and lets us hit R-49 at roughly 13 inches depth. Cellulose handles Schertz’s 150°F+ summer attic temperatures well - it doesn’t slump like fiberglass can when daily thermal cycling stresses the material. For the volume-builder homes along IH-35, we often recommend cellulose because it fills irregular joist bays and buries the wiring penetrations that builders left unsealed. A typical full attic replacement in a 2,000-square-foot Schertz home runs $2,400-$3,600 including air sealing.

Blown-In Fiberglass

We stock Knauf and Johns Manville fiberglass for Schertz homeowners who prefer the material - often landlords or investors who want the lower upfront cost and don’t mind the slightly lower R-value per inch (R-2.5-R-3.0). Fiberglass works best in attics with good access and relatively uniform joist spacing, which describes fewer Schertz tract homes than you’d think. Where we do use it: top-ups over existing fiberglass that’s still in decent shape, or in combination with cellulose - fiberglass at the eaves for wind-washing resistance, cellulose over the field. Budget $1,800-$2,800 for a fiberglass top-up in a standard Schertz attic.

Dense-Pack Wall Insulation

Schertz’s post-2000 homes are almost all framed with 2×4 exterior walls - too shallow for batts to perform well, and many were left with empty cavities at the builder’s discretion. Dense-pack cellulose, blown at 3.5-4.0 pounds per cubic foot, fills those cavities completely and cuts air infiltration through the wall assembly by 40-60% in our blower-door measurements. This matters especially for the two-story homes off Wiederstein Road where the second-floor walls get hammered by afternoon sun. Dense-pack wall work in Schertz typically runs $3,500-$5,500 for a full home, depending on cavity count and siding type.

Blown-In Top-Up

Here’s where we differ from every other contractor in this market: we will not blow a top-up over an unsealed attic floor. Period. Schertz’s builder-grade R-30 cellulose has settled to R-22-R-26 at the eaves, and the temptation is to just add six more inches and call it R-49. But those open top-plate gaps and unsealed can lights? They short-circuit the new insulation in months. Our top-ups include air sealing of top plates, recessed cans, and duct penetrations as a hard prerequisite - not an upsell. A sealed-and-topped Schertz attic runs $2,200-$3,800.

Trusted Brands We Service in Schertz

We source cellulose from GreenFiber, fiberglass from Owens Corning and Johns Manville, and mineral wool from Knauf - no proprietary lock-in, no house brand pushed for margin. For Schertz customers, this means we match the material to the application and the budget, not to a distributor incentive. We keep common densities and blower settings in our San Antonio warehouse, so a Schertz crew isn’t waiting on a special order while your attic sits open. Every bag is labeled, every installation depth is photographed, and every material spec is noted in your written scope.

Common Blown-In Insulation Problems We See in Schertz Homes

• Settled builder cellulose at the eaves. The R-30 blown cellulose installed during the 2002-2022 tract build-out has compressed to R-22-R-26 where wind-washing off FM 3009 and IH-35 is strongest. We measure this with a depth gauge on every estimate - no guessing from the hatch.
• Skipped air sealing at top plates and penetrations. Volume builders in Schertz routinely left top plates, recessed can lights, and duct boot penetrations open to the attic. Blowing new insulation over these gaps just buries the problem; the 150°F+ June-September attic air pulls straight through the ceiling drywall.
• PCS turnover exposing hidden defects. A JBSA-Randolph family buys a 2016 Lennar near Cibolo Creek, accepts the energy bills as “Texas normal,” then PCS-moves and the new owner or landlord gets hit with the first full summer. The insulation was always inadequate; it just took a new occupant to notice.
• Post-Uri freeze damage to compromised envelopes. The February 2021 Winter Storm Uri exposed how poorly Schertz’s minimum-code homes retain heat. Homes with settled attic insulation and unsealed top plates saw indoor temperatures drop 20-30°F faster than sealed-and-insulated neighbors, creating a secondary market for wall and attic upgrades that barely existed before.
