Fast, Reliable Blown-In Insulation Across Schertz
Most blown-in insulation jobs in Schertz run $1,800-$3,400 for a typical attic top-up and are completed in a single day. We dispatch crews from our San Antonio office and carry full material loads so we don’t stop mid-job, which matters on the tight timelines military families near JBSA-Randolph often face. Call (830) 243-6352 for a written price before any work starts.
We’ve worked the Schertz Pkwy corridors, the Savannah subdivision, and the FM 1518 strips near the base long enough to know what we’ll find before we open the attic hatch. Schertz’s housing stock is remarkably uniform - almost entirely 1990s-2010s slab-on-grade tract homes built to the same minimum-code R-30 spec - which means the failure pattern is uniform too. That predictability lets us quote accurately and show up with the right material load the first time.
Why Topside Attic Insulation New Braunfels Is Schertz’s Preferred Blown-In Insulation Company
Our Blown-In Insulation team has sealed and insulated more than 9,000 homes since 2016, and Schertz represents one of our most concentrated service areas. The city’s single-generation housing stock means our technicians recognize the framing, the vented attic configurations, and the settled fiberglass depths from the street address. Reviews from Schertz customers consistently note the one-trip completion and the documented photo record they receive before we leave.
We answer calls with a live person, 24/7 - no voicemail loops, no callback windows measured in business days. For Schertz properties, that means same-day scheduling is often available, and our crews carry enough Owens Corning and GreenFiber material to complete a full attic top-up without a resupply run. Dispatch and scheduling are coordinated from our San Antonio office; crews serve Schertz locally.
Under The Haven Standard, every job begins with a written price and ends with a documented record. On applicable jobs, we publish before-and-after blower-door numbers so you can verify the air-sealing result in a single figure - the pressurization reading that tells you exactly how much conditioned air your home was losing before and after the work.
Our Blown-In Insulation Services in Schertz
Blown-In Cellulose
We install GreenFiber cellulose in Schertz attics where homeowners want a recycled-content option with strong resistance to air movement. Cellulose performs well in Schertz’s vented attics because it packs tighter around irregular framing and top plates than fiberglass, which matters in the low- to mid-pitch roofs common to DR Horton and KB Home builds. A typical Schertz attic cellulose job runs $2,200-$3,800 depending on square footage and whether we need to remove settled existing material first.
Blown-In Fiberglass
Blown-In Fiberglass is what most Schertz attics were built with, and it’s what most need restored. We source from Owens Corning and Johns Manville - no proprietary lock-in - and blow to the depth that achieves your target R-value, not just what fits. In Schertz’s 150°F+ vented attics, the original R-30 spec has often compressed to an effective R-15; we measure what’s there, air-seal first, then blow to the depth that actually performs. Most Schertz fiberglass top-ups run $1,800-$3,200.
Dense-Pack Wall Insulation
Dense-pack wall insulation fills the empty stud cavities in Schertz’s 1990s-2010s tract homes, many of which were built with no wall insulation at all or with thin batts that settled. The 2021 Winter Storm Uri exposed how many Schertz homes had uninsulated exterior walls - pipes froze in cavities that should have been protected. We dense-pack with cellulose or fiberglass at 3.5 pounds per cubic foot, which settles less and blocks convection loops. This is slower work than attic blowing; a typical Schertz dense-pack job runs $3,500-$6,000 and requires a crew that shows up with enough material to finish, because stopping mid-cavity means tearing drywall twice.
Blown-In Top-Up
Blown-In Top-Up is our most common Schertz service. On a one-trip blown-in top-up off the Schertz Pkwy corridor in Savannah, our tech opened an attic that still held its 2002-vintage builder blown fiberglass, now settled to roughly half the spec depth over a 160°F deck; we air-sealed the top plates, then blew in Owens Corning fiberglass to restore the rated R-value. Because we carried the full rig, the job closed out same-day with an attic card and no return visit. Most Schertz top-ups run $1,800-$2,800 and include the blower-door test that proves the result.

AfterTrusted Brands We Service in Schertz
We stock Owens Corning, Johns Manville, and GreenFiber materials on every Schertz rig - no special-order delays, no mid-job resupply runs. These are standard manufacturer products, not proprietary blends, so you can cross-reference specs and pricing independently. We also work with Demilec spray foam on jobs where blown-in isn’t the right solution, though this page covers our blown-in and dense-pack services specifically. Our technicians carry product data sheets on the truck; you get the manufacturer, the R-value per inch, and the installed depth in your written scope before anyone starts.
Common Blown-In Insulation Problems We See in Schertz Homes
- Settled builder-grade fiberglass below effective R-value. Because most Schertz homes are 1990s-2010s slab-on-grade tract builds sharing one builder-minimum R-30 attic spec, the failure is uniform city-wide: near JBSA-Randolph, original blown fiberglass reads around an effective R-15 on a blower-door test, so upgrades can be scoped and quoted from the street’s build year rather than a one-off inspection.
- Insulation installed over unsealed air leaks. Blown-in installed over unsealed top plates and can lights in these 1990s-2010s layouts lets conditioned air bypass the blanket, so the added R-value never shows up on the utility bill. We seal first, then insulate - in that order.
- Crews arriving under-supplied for the job scope. Uniform volume-built framing and low- to mid-pitch roofs leave little room to maneuver, so a crew that shows up light has to stop and resupply mid-job - often leaving dense-pack wall insulation unfinished on a PCS-clock deadline. We carry full loads.
- Wall cavities empty or under-insulated since construction. Pre-2010 Schertz homes typically predate the IRC energy code cycles that pushed better wall insulation, leaving a large retrofit market. The 2021 freeze exposed how many homeowners didn’t know their walls were hollow.
Pricing for Blown-In Insulation in Schertz, TX

These ranges reflect what we actually quote on Schertz jobs - not national averages. A 1,800-square-foot tract home near Universal City Road with a straightforward attic top-up and moderate air sealing typically lands in the lower half of the fiberglass range. A larger home on FM 1518 needing wall dense-pack and attic work together pushes toward the upper end. Every quote is a flat, written price with scope and warranty delivered before anyone lifts a tool - Haven Standard Clause 1. Call (830) 243-6352; estimates are free.

FAQs - Blown-In Insulation in Schertz
The original R-30 is almost never still performing at spec. In Schertz’s vented attics, builder-grade blown fiberglass settles and compresses over 15-25 years to roughly half its original depth, producing an effective R-value closer to R-15. We measure this with a depth probe during our initial inspection and show you the photo. Call (830) 243-6352 for a free estimate - we’ll put a number on what’s actually up there.
Yes. We carry full material loads and the complete blower rig on every Schertz truck, so a standard attic top-up or full blow closes out same-day. The only exceptions are jobs requiring extensive insulation removal or wall dense-pack with interior drywall access, which we scope and schedule accordingly. One-trip completion is standard, not a special request.
Blown-in will cut conductive heat gain, but only if the attic is air-sealed first. In Schertz’s 150°F+ vented attics, unsealed top plates and can lights let conditioned air escape continuously, so new insulation sits on a leaky floor. We blower-door test before and after sealing so you see the air-loss number drop. The insulation then has a fighting chance. Call (830) 243-6352 and we’ll run the pressurization test with the estimate.
We install Owens Corning and Johns Manville fiberglass and GreenFiber cellulose for blown-in attic work, and dense-pack with cellulose or fiberglass at 3.5 pounds per cubic foot for wall cavities. Product selection depends on your target R-value, budget, and whether you prefer recycled content. We publish the manufacturer and spec in your written scope - no proprietary blends, no hidden product switches.
It depends on your hold time, but Schertz’s compressed attic stock means even a partial top-up produces measurable utility savings in the first summer. For military families on 2-to-3-year PCS cycles, we often scope a targeted air-seal plus blown-in top-up that pays back within 18 months and improves resale appeal. We don’t upsell spray foam or full encapsulation unless the math works for your timeline. Bring us your situation and we’ll write a scope that fits.
