Fast, Reliable Attic Insulation Across Schertz
Most attic insulation jobs in Schertz run $1,800-$4,200 depending on whether we’re topping up existing material or starting from a stripped attic floor. Our crews are dispatched from the San Antonio office and typically arrive in Schertz within 45 minutes, including neighborhoods off FM 3009, Wiederstein Road, and the Cibolo Creek corridor. We know these homes because we’ve worked in them: the DR Horton, Lennar, and Centex tracts built between 2002 and 2022 that dominate Schertz’s housing stock were insulated to IECC 2009-era code minimums of roughly R-30, well below the current R-49 recommendation for Climate Zone 2. If your upstairs won’t hold temperature or your summer electric bills top $300, the attic is the first place we look.

Why Topside Attic Insulation Converse Is Schertz’s Preferred Attic Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in Schertz’s fast-growing subdivisions. Our reviews from Schertz customers consistently mention the same thing: we show the blower-door numbers, not just tell. One homeowner in the Pecan Grove area wrote that our before-and-after pressurization readings - 4,100 CFM50 down to 2,200 - were the first time anyone had documented what their builder left unfinished.
Response time matters in July. When attic temperatures in Schertz push past 150°F, a same-day assessment can mean the difference between a manageable top-up and a heat-stressed HVAC compressor. We answer calls 24/7 with a live person, and our crews carry Knauf and Owens Corning stock on the truck for most Schertz attic configurations.
Our local knowledge runs deeper than zip codes. We know which Schertz subdivisions used fiberglass batts versus blown cellulose, which builders skipped attic baffles at the soffits, and where the duct chases were left unsealed. That specificity saves time and money on every job.
Our Attic Insulation Services in Schertz

Blown-In Attic Insulation
Blown-in fiberglass or cellulose is our most common service in Schertz because it integrates cleanly with the existing R-30 batts in most tract homes. We air-seal first - top plates, recessed can housings, duct penetrations - then blow Owens Corning or Knauf R-49 over the top, filling the joist cavities and covering the settled edges where your original insulation has compressed to R-20 or less. The result is a continuous thermal blanket with no thermal bridging. Most Schertz blown-in jobs run $2,400-$3,800 for a 2,000-square-foot attic footprint.

Attic Batt Insulation
For Schertz homes with limited attic access or localized problem areas - a bonus room over the garage, a master suite wing that never cools - we install Rockwool or Johns Manville batts in precise cuts. Batt work is more labor-intensive, so we reserve it for areas where blown-in would require extensive prep or where the homeowner needs to maintain walkable attic paths for storage. Typical batt-only jobs in Schertz range from $1,800-$2,800.

Attic Insulation Top-Up
This is the service most Schertz homeowners actually need. Your builder installed R-30. Climate Zone 2 now calls for R-49. A top-up adds R-19 to R-20 of blown material over your existing layer, bringing you to full current recommendation without the cost of full removal. We see this constantly in Schertz’s 2010-2018 builds - the insulation looks fine from the attic hatch, but thermal imaging shows edge settlement and compression from HVAC service traffic. Top-ups in Schertz typically cost $1,800-$2,800 and can be completed in a single day.

Attic Insulation Replacement
When existing insulation has been compromised by moisture, rodent activity, or repeated compression, we strip to the attic floor, seal every penetration, and reinstall fresh material to R-49. Full replacement is more common in Schertz than you’d expect - those same builder-grade batts have been walked on by HVAC techs for a decade, and holiday storage boxes have crushed the center of many attics. Replacement jobs run $3,200-$4,800 in this market.

Attic Baffles & Ventilation Prep
Schertz’s 150°F attic temperatures make ventilation critical. Baffles - the foam or cardboard channels we install between rafters at the soffit - keep intake airflow open after insulation is added. Without them, blown material blocks the soffit vents and turns your attic into a stagnant heat box. We check baffle presence on every Schertz job; in our experience, roughly half the homes built between 2005 and 2015 either lack them entirely or have baffles that collapsed during construction. Baffle installation and soffit prep adds $400-$700 to a typical job.

Common Attic Insulation Problems We See in Schertz Homes

- Builder-grade R-30 batts settled to R-22 at the edges. In Schertz’s 2002-2022 tract homes, the original fiberglass was installed to minimum code and never meant to handle foot traffic from HVAC service or storage. We regularly find the perimeter of the attic - where the upstairs bedrooms sit - reading 40% below target R-value while the center looks fine.
- Unsealed top plates and recessed cans pulling 150°F attic air into conditioned space. Fast-track builders in Schertz’s FM 3009 and Wiederstein Road subdivisions skipped air sealing at electrical penetrations and duct chases. No amount of added insulation fixes this; the hot air finds the path of least resistance straight into your return plenum. Our blower-door test catches it every time.
- Missing or collapsed attic baffles blocking soffit ventilation. Without proper baffles, blown insulation migrates to the eaves and chokes off intake airflow. In Schertz’s climate, that stagnant attic heat radiates downward through the ceiling drywall, making upstairs rooms run 4-7°F warmer than downstairs even when the HVAC is sized correctly.
- Military families discovering underperformance after the warranty closes. JBSA-Randolph PCS cycles mean a steady turnover of Schertz homeownership. The family that accepted “it meets code” in 2018 is long gone; the 2023 buyer inherits R-30 in a Climate Zone 2 summer and wonders why their electric bill hit $340. We see this pattern repeat across Schertz’s military-heavy subdivisions.

FAQs - Attic Insulation in Schertz

Because your 2015 builder installed R-30 fiberglass batts to IECC 2009 minimums, and Climate Zone 2 now recommends R-49. In Schertz’s subdivisions off FM 3009 and Wiederstein Road, we’ve found those batts settled 20-30% at the edges within five years, especially where HVAC techs walked the joists or homeowners stored boxes. The home isn’t falling apart; it was built to a standard that’s now two code cycles behind current recommendation. Call (830) 420-0953 and we’ll measure what you actually have versus what you need.
For most Schertz homes, the R-49 top-up delivers more measurable comfort improvement per dollar. Radiant barriers work best when attic ventilation is already optimized and insulation is at full depth; in Schertz’s builder-grade homes, we typically find both under-insulation and blocked soffit airflow. We air-seal, add baffles, top up to R-49, then evaluate whether radiant barrier sheathing or foil adds incremental value. Most homeowners see their August bill drop $50-$80 with insulation alone. Call for a free assessment and we’ll show you the numbers.
Construction variance in fast-tracked Schertz subdivisions is real. One crew sealed top plates; yours didn’t. One attic got proper baffles; yours has collapsed cardboard blocking the soffits. One homeowner had the HVAC contractor add return air pathways; yours runs on the original undersized duct. We see 10-15% performance variance between identical floor plans on the same street. Our blower-door test and thermal imaging pinpoint exactly where your envelope leaks differently. Call (830) 420-0953 for a free estimate - we’ll show you the specific gaps.
Insulating before listing makes sense if the home’s summer electric bills are high enough to scare renters or buyers. In Schertz’s military rental market, a documented R-49 attic with before-and-after blower-door readings sets your listing apart from the dozen similar tract homes on the same rotation cycle. We provide the written scope, photo record, and performance documentation that transfers cleanly to the next owner. For landlords specifically, the energy savings often justify the investment over a 24-month lease term. Call for a written price and we’ll run the math with you.
Not if the existing material is dry, uncontaminated, and structurally intact. In most Schertz top-up jobs, we air-seal over the existing batts, add baffles where missing, and blow new material on top. The exception: rodent damage, moisture staining, or severe compression from years of foot traffic. We assess this during our initial attic inspection and document the condition with photos you receive before any work starts. Full removal and replacement adds roughly $1,200-$1,800 to the job. Call (830) 420-0953 for a free inspection and we’ll tell you exactly which path applies.
