Fast, Reliable Attic Insulation Across Converse
Attic insulation in Converse typically runs $1,800-$4,200 for most homes, with same-week scheduling available and crews dispatched from our San Antonio office. If your cooling bills keep climbing despite a newer HVAC system, the problem is almost certainly in your attic, and it’s probably worse than it looks from the hatch.
We serve Converse from our San Antonio dispatch office, and we’re familiar with the specific failure patterns that hit this market harder than most of the metro. The 1980s-2000s tract homes around JBSA-Randolph, the Gulf moisture pushing through unsealed top plates, the attic temperatures that crack 150°F in July - we’ve documented all of it.

Why Topside Attic Insulation New Braunfels Is Converse’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a significant cluster of those jobs sits in the Converse and JBSA-Randolph corridor. Our crews know the difference between a 1987 Ryan Home on the rental streets east of the base and a 2005 build in the newer sections near FM 78. That matters because the failure patterns are different, and the fix has to match.

Our Attic Insulation Services in Converse
Blown-In Attic Insulation
Blown-In Insulation - Converse is our most common install, and for good reason. The 1980s-2000s tract homes here were built with thin R-19 batts that have compressed, shifted, or been torn open by years of HVAC service access. Blown-in cellulose or fiberglass fills the gaps those batts never reached and provides a uniform thermal blanket across the attic floor. We source from Owens Corning, Johns Manville, and GreenFiber, so we’re not locked into a single proprietary product. On a typical 1,600-square-foot Converse attic, we’ll air-seal first - top plates, duct chases, can-light penetrations - then blow to a consistent depth, usually R-38 to R-49 depending on your roof structure and budget.
Attic Batt Insulation
Batt insulation still has a place in Converse, particularly on partial installs or in attics with complex framing where blown-in would drift. We use Knauf and Owens Corning batts when the job calls for them, but we’re direct with customers: batts only perform if they’re cut to fit tightly around every obstruction and if the attic is air-sealed first. In the JBSA-Randolph rental market, we’ve seen too many original batts shoved aside by rotating HVAC crews to recommend batt-only solutions without addressing the access and compression problem. When we do install batts, we document the fit with photos and provide a blower-door reading to prove the envelope is holding.
Attic Insulation Top-Up
The top-up is our most frequent service call in Converse, and it’s the right move for a lot of homeowners here. If your original insulation is still in place but compressed below its labeled R-value, a top-up of blown-in material over the existing layer can restore performance without the cost of full removal. We see this constantly on the military-rental streets east of JBSA-Randolph: the batts are still there, technically, but they’ve been walked on, shoved against ductwork, or pulled back for electrical work and never replaced properly. We assess what’s salvageable, air-seal the penetrations that have been exposed, and blow new material to the target depth. Most Converse top-ups run $1,800-$2,800.
Attic Insulation Replacement
Full replacement makes sense when the existing material is contaminated, water-damaged, or so degraded that a top-up would be lipstick on a pig. In Converse, we recommend replacement most often on homes where the original R-19 batts have been cooked by years of 150°F attic temperatures and are crumbling to dust, or where rodent activity has rendered the insulation unusable. We remove the old material, HEPA-vacuum the attic deck, seal every penetration, and install new blown-in or batt insulation to modern standards. Replacement jobs in Converse typically range from $3,200-$4,800 depending on attic square footage and accessibility.
Attic Baffles & Ventilation Prep
Converse’s vented attics need functioning intake ventilation at the soffits, and that’s where baffles come in. A baffle - also called a vent chute or rafter mate - is a simple channel that keeps insulation from blocking the soffit vents while maintaining a clear air path from eave to ridge. Without them, hot air stagnates in the attic, and your insulation works against itself. On nearly every Converse job, we install Owens Corning Rafter-Mates or equivalent baffles before blowing insulation, especially on the older tract homes where original baffles were never installed or have collapsed. It’s a small detail that prevents a major performance failure.

Before
AfterTrusted Brands We Service in Converse
We stock and install materials from Owens Corning, Johns Manville, Knauf, and other major manufacturers, with no proprietary lock-in that limits your options. For Converse homes dealing with Gulf moisture and extreme attic heat, we specify products rated for high-temperature stability and moisture resistance - not the cheapest SKU on the pallet. Our San Antonio warehouse carries standard depths and densities for quick turnaround on Converse jobs, and if your project calls for something specific like Rockwool for fire resistance or GreenFiber for density and sound dampening, we source it without markup games. Every bag is documented in your written scope, and every install is photographed for your record.
Common Attic Insulation Problems We See in Converse Homes
- Batts shoved aside by rotating HVAC crews. On the rental streets east of JBSA-Randolph, we regularly pull attic hatches to find original Owens Corning or Johns Manville R-19 batts wadded around air handlers or shoved into corners by years of service visits. The insulation looks present from the hatch but leaves whole ceiling bays essentially uncovered.
- Gulf moisture degrading fiberglass through vapor drive. Converse sits close enough to the Gulf that summer humidity pushes through unsealed top plates and duct chases. Fiberglass batts absorb that moisture, lose loft, and drop effective R-value even when they look intact. Air sealing is the fix, not replacing the batts with more batts.
- 150°F attic temperatures cooking original materials. Converse summer highs hit 98-102°F regularly, and vented attic temperatures can exceed 150°F. Builder-grade batts installed in the 1990s or 2000s weren’t spec’d for that thermal load long-term. The binder breaks down, the fibers separate, and the insulation settles into a thin, ineffective layer.
- Zero air sealing at top plates and penetrations. The 1980s-2000s Converse tract homes were built before modern Texas energy codes required comprehensive air sealing. Conditioned air leaks straight into the attic through gaps around drywall, electrical boxes, and plumbing stacks, making even decent insulation perform poorly. Our blower-door tests on these homes routinely start at 3,500-4,500 CFM50 before we seal.

FAQs - Attic Insulation in Converse
Because the damage is usually hidden from the hatch. On a rental property east of JBSA-Randolph, our crew pulled the attic hatch and found the original Owens Corning R-19 batts shoved off the attic floor and wadded around the air handler by years of rotating HVAC service visits, leaving whole bays of the ceiling with almost no cover. We air-sealed the top plates and duct penetrations first, then blew GreenFiber to a uniform depth and added Owens Corning Rafter-Mates baffles at the soffits so the intake vents stayed open. The tenant’s summer cooling run-time dropped noticeably the first week, and the property manager has since flagged two more houses on the same street for top-ups. Call (830) 243-6352 and we’ll inspect what’s actually happening beyond the hatch - estimates are free.
Yes, through a process called vapor drive. Summer humidity from the Gulf pushes into your attic through unsealed top plates, electrical penetrations, and duct chases. Fiberglass batts absorb that moisture, lose their loft, and drop effective R-value even when they look fine. The 1980s-2000s tract homes in Converse were built with no air sealing, so this happens predictably. The fix is sealing first, then insulating - not replacing wet batts with dry batts that will just get wet again. Our Attic Insulation team includes blower-door verification on every applicable job so you can see the air-leakage reduction in actual numbers.
Probably a top-up with air sealing, but we need to see the attic. If the original batts are still in place but compressed or disturbed, we can often blow new material over the existing layer after sealing penetrations, at roughly half the cost of full removal and replacement. If the batts are crumbling, contaminated, or soaked with condensation damage, replacement is the better investment. We’ll tell you which after inspection, and we’ll show you photos so you can see what we see. Call (830) 243-6352 for a written price either way.
Modern blown-in cellulose and fiberglass are rated for sustained attic temperatures well above 150°F, so properly installed new material won’t degrade the way 1990s builder-grade batts have. The bigger risk is installing insulation without addressing the heat source: unsealed ductwork, dark roofing, or blocked ventilation. We specify high-temperature-stable products from Owens Corning and Johns Manville, and we always pair insulation with baffles and ventilation prep so your attic can breathe. The goal isn’t just adding material; it’s making the entire system work together.
Yes, regularly. We dispatch crews to Converse from our San Antonio office, and the JBSA-Randolph rental market is one of our most active service areas. We understand the specific patterns: compressed batts, unsealed top plates, HVAC-crew damage, and the cooling-load strain that hits these homes every July and August. If you’re in Converse, Universal City, or the streets east of the base, we’re already working your neighborhood. Call (830) 243-6352 for same-week availability.
