Fast, Reliable Blown-In Insulation Across Converse
Blown-in insulation in Converse typically runs $1.80-$3.20 per square foot for attic top-ups and $2.50-$4.50 for full removal-and-replacement with air sealing, with most jobs completed in a single day. Our crews serve Converse directly from our San Antonio office, and we routinely work the military-rental corridors near JBSA-Randolph where original 1990s insulation has been disturbed by years of HVAC access. Call (830) 243-6352 for a written price before any work starts.
We’ve insulated enough homes off Toepperwein Road, Woodlake Parkway, and the streets east of the base to know the pattern: builder-grade R-19 batts shoved aside around ductwork, compressed by boots, never put back. The attic looks insulated from the hatch. It isn’t. That’s why every job we do in Converse starts with a photo-documented inspection, a written scope, and a flat price you approve before we touch anything.
Why Topside Attic Insulation New Braunfels Is Converse’s Preferred Blown-In Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our blower-door failures - homes that started leaky and ended tight - come from the 1980s-2000s tract stock in Converse. The reviews we get from Converse homeowners mention the same things: the technician texted when he was en route, the written price matched the final invoice, and the photo record showed exactly what changed in the attic.
Our response time to Converse is typically same-day or next-day for estimates, and we don’t book beyond capacity. When you call (830) 243-6352, a live person answers. No callback queue. That’s Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
We know the local conditions that matter. Converse’s summer attic temperatures exceed 150°F. Gulf moisture pushes vapor through unsealed top plates. And the rental turnover near JBSA-Randolph means most attics have never been properly inspected, let alone upgraded. We account for all of it in the scope.
Our Blown-In Insulation Services in Converse
Blown-In Cellulose
We use GreenFiber cellulose on most Converse attics because it performs well in our climate - dense enough to resist air movement, treated with borate for fire and pest resistance, and it fills irregular joist bays better than batts ever could. On a typical 1,800-square-foot Converse tract home with a vented attic, we’ll air-seal first (top plates, can lights, plumbing and electrical penetrations), then blow a uniform R-38 blanket. The cellulose we install is manufactured from recycled paper and doesn’t lose R-value to moisture absorption the way compressed fiberglass can. Most jobs run $2,800-$4,200 for full attic coverage with air sealing included.
Blown-In Fiberglass
For homeowners who prefer fiberglass, we stock Owens Corning and Johns Manville loose-fill products. Fiberglass works well in Converse when the attic is properly air-sealed first - which we require. We won’t blow fiberglass over an unsealed attic floor. The Gulf moisture vapor drive in this market will degrade it. Our crews use conditioned blowing equipment to achieve consistent density, and we verify depth with a ruled probe across multiple attic locations, not just one spot near the hatch.
Dense-Pack Wall Insulation
Many Converse homes from the 1980s and 1990s were built with empty stud cavities or minimal batt insulation in exterior walls. Dense-pack cellulose fills those cavities completely, slowing both heat transfer and air infiltration. We access walls through exterior siding or interior drywall as the scope requires, and we always verify fill density with a tube-fill calculation - no guesswork. This service runs $3.50-$5.50 per square foot of wall area in Converse, depending on access method and cavity condition.
Blown-In Top-Up
Not every Converse attic needs full removal. If your existing insulation is in reasonable shape - not compressed, not moisture-damaged, not disturbed around ductwork - we’ll air-seal the penetrations and blow a top-up layer to reach current code minimums. A typical top-up to R-38 on a 1,500-square-foot Converse attic runs $1,800-$2,800. But we’ll tell you honestly if your attic needs removal first. We’ve seen too many top-ups blown over compressed, displaced batts that were doing nothing. That’s not a top-up. That’s burying a problem.

Before
AfterTrusted Brands We Service in Converse
We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber - no proprietary lock-in, no house brand pushed for margin. For Converse homeowners, this means we match the material to the application: GreenFiber cellulose for most attic restorations, Owens Corning fiberglass when specified, dense-pack products from Johns Manville for wall cavities. We keep common blowing materials stocked locally, so we’re not waiting on a distributor while your attic sits open. Every bag is documented in your photo record, and every install depth is verified before we leave.
Common Blown-In Insulation Problems We See in Converse Homes
- HVAC-disturbed batts with no remediation. On the military-rental streets east of JBSA-Randolph, we regularly find original R-19 fiberglass pushed off duct runs and trunk lines by rotating service crews, then never restored. The attic looks insulated from the hatch. Thermal imaging shows bare drywall over the living space.
- Zero air sealing at top plates and penetrations. Converse’s 1980s-2000s builder-grade construction predates modern Texas energy code air-sealing requirements. That means 150°F attic air and Gulf moisture vapor drive straight into conditioned space through gaps around can lights, plumbing vents, and wire penetrations. Any insulation added without sealing first is compromised from day one.
- Moisture-degraded fiberglass sagging off joists. Converse’s humidity and vented attic design create conditions where fiberglass batts absorb moisture, lose loft, and sag away from the ceiling plane. The result is thermal bridging - hot spots where insulation should be - and a simple blown-in top-up won’t fix it without removal and drying first.
- Attic hatches with no weatherstrip or insulation. We see this on nearly every Converse home we inspect: a plywood hatch sitting on unsealed drywall, leaking conditioned air like an open window. It’s a five-minute fix that most crews skip. We don’t.

FAQs - Blown-In Insulation in Converse
It depends on what we find when we lift the hatch. If the existing batts are merely thin but still in place, uncompressed, and dry, we’ll air-seal and top up. If they’re shoved aside around ductwork, compressed by HVAC boots, or moisture-stained - which we see on most military-rental streets east of the base - removal is necessary first. Blowing new material over displaced batts just buries the problem. We’ll photograph what we find and give you a written price for both scenarios before you decide. Call (830) 243-6352 to schedule an inspection - estimates are free.
The combination of extreme attic heat and humidity vapor drive means unsealed attics degrade any insulation type over time. In Converse, a vented attic without air sealing at the ceiling plane will pull moist outdoor air through the insulation in summer, reducing effective R-value and potentially supporting mold on the drywall. That’s why our Blown-In Insulation protocol requires air sealing before blowing - not after, not optional. The blower-door test we perform before and after documents the improvement in envelope tightness, so you can verify the result.
Yes. We’ve worked attics in Converse’s tighter 1980s townhome clusters and alley-load configurations where the only access is a 22-inch scuttle in a closet ceiling. Our blowing equipment breaks down for tight access, and we protect finished spaces with drop cloths and containment. If the hatch is too small for a technician to inspect safely, we’ll note that in the written scope and recommend a hatch enlargement as a separate line item. Call (830) 243-6352 and we’ll walk through your access constraints before we schedule.
Current Texas energy code minimum for attic insulation in our climate zone is R-38, which translates to roughly 10-12 inches of blown cellulose or 14-16 inches of loose fiberglass depending on product density. We verify with a ruled depth probe at minimum six locations per attic - not one convenient spot near the hatch - and we photograph each reading for your documented record. If we quote a top-up to R-38, you’ll have the photos to prove we hit it.
Yes, and it’s distinct to that area. The high turnover of military renters and the frequency of HVAC service calls mean attics get accessed repeatedly by different technicians who don’t own the insulation they disturb. We find original R-19 batts compressed, torn, or pushed completely off duct runs, with no one responsible for restoring them. The homeowner or new buyer inherits an attic that looks insulated but performs like bare drywall. On a 1990s slab-on-grade home off Toepperwein Road east of the base, our crew found the original R-19 fiberglass batts pushed aside and compressed around the air handler and trunk lines, with visible gaps where years of HVAC access had torn the facing. We air-sealed the top plates and duct penetrations, then blew in GreenFiber cellulose to restore a uniform R-38 blanket across the entire vented attic. The homeowner immediately noticed the rear bedrooms held temperature during a 101°F afternoon instead of cycling nonstop. Call (830) 243-6352 if you’re buying or own in that corridor - we’ll inspect and document what you’ve actually got.
