Fast, Reliable Attic Insulation Across Converse
Most attic insulation jobs in Converse run $1,800-$4,200 depending on attic square footage and whether air sealing is needed first, and our crews typically start work within 48 hours of the initial visit. We dispatch from our San Antonio office and carry Owens Corning, Johns Manville, and Knauf materials stocked for Converse’s specific housing stock - the 1993-2012 brick-veneer tract homes that dominate neighborhoods from Woodlake to Rolling Ridge. Call (830) 402-5240 for a written price before any work starts.
Converse sits in the northeast San Antonio metro where summer attic temperatures routinely exceed 140°F. That heat doesn’t stay in the attic. It pushes through under-insulated ceilings, non-airtight recessed can lights, and unsealed top plates into the living space below, driving cooling bills past $300 monthly for homes along FM 78 and Kitty Hawk Road. We’ve worked in enough of these houses to know the pattern before we pull the attic ladder down.
Why Topside Attic Insulation Schertz Is Converse’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a significant share of them have been in Converse’s dense corridors of military-family housing. Our reviews from Converse customers consistently mention the same thing: we show the blower-door numbers. A pressurization reading that tells you, in one figure, how much conditioned air your home was losing before we started and how much less it loses after we’re done. No feeling-based claims. Just the measurement.
Response time to Converse is typically same-day or next-day for estimates. Our technicians are background-checked, uniformed, and text when they’re en route - Haven Standard: Arrive on schedule, you get a named technician. Calls are answered by a live person 24/7, not a callback queue measured in business days.
We know the local building era. The slab-on-grade brick-veneer homes from the 1990s and 2000s, the original R-30 blown fiberglass that has settled to R-19 or lower, the non-IC-rated can lights that builders installed as standard practice before airtight assemblies became code. This isn’t generic suburban housing. It’s a specific failure mode we’ve documented hundreds of times.
Our Attic Insulation Services in Converse

Blown-In Attic Insulation
Blown-in fiberglass or cellulose is the right fix for most Converse attics because it fills irregular joist bays and covers the settled original material without requiring full removal. We install to current Texas energy code targets of R-38 to R-49, not the R-30 that was standard when these homes were built. In the Woodlake and Rolling Ridge subdivisions, we’ve found that topping up over unsealed air leaks is wasted money - so our Attic Insulation team always air-seals top plates, can lights, and penetrations before the blower truck arrives. The result is insulation that actually performs at its rated R-value instead of being short-circuited by thermal chimneys.

Attic Batt Insulation
Batt insulation has a place in Converse homes with accessible attic storage areas or defined knee-wall spaces where blown material would be impractical. We use Owens Corning and Johns Manville batts cut to fit, not stuffed and compressed. Compression kills R-value. In the townhome-style units near Universal City limits with tighter attic clearances, batts sometimes make more sense for the crew and the finished result. We still seal first. Always.

Attic Insulation Top-Up
This is the most common call we get in Converse, and it’s where we have to be honest with homeowners. A top-up - adding new material over old - only works if the attic floor is airtight. We’ve inspected too many homes off FM 78 where a previous contractor blew new fiberglass over settled old fiberglass and left the can lights leaking. The homeowner got a slightly thicker layer of underperforming insulation. We won’t do that. Our top-ups include air sealing of all accessible penetrations, baffles at soffit vents to prevent wind-washing, and a post-work blower-door test so you can verify the result. Most Converse top-ups run $1,800-$3,400.

Attic Insulation Replacement
Full removal and replacement makes sense when the original material is contaminated, water-damaged, or so compressed that it can’t be recovered. In Converse’s rental-heavy market, we’ve removed insulation degraded by roof leaks that absentee landlords deferred, or by rodent activity in attics that went unsealed for years. Replacement includes complete removal, sanitization if needed, air sealing, and new blown-in to R-38 or R-49. Typical range in Converse: $3,200-$5,800 depending on attic size and accessibility.

Attic Baffles & Ventilation Prep
Converse’s 140°F+ attic temperatures make ventilation critical. Baffles - the cardboard or foam channels we install between rafters at soffit vents - keep incoming air flowing over the insulation rather than pushing through it. Without baffles, wind-washing strips heat from the insulation in winter and reduces effective R-value year-round. In the older sections of Woodlake where soffit vents were minimal or blocked by original construction, we often add baffles as part of any insulation job to ensure the assembly breathes properly.

Trusted Brands We Service in Converse
We source from Owens Corning, Johns Manville, Knauf, and GreenFiber - no proprietary lock-in, no single-source product pushing. For Converse’s climate and housing stock, we typically specify Owens Corning blown fiberglass for its recovery after compression and Johns Manville batts for defined spaces. Knauf’s EcoFill cellulose performs well in attics where homeowners prefer a recycled-content option. We stock these materials locally, so we’re not waiting on a delivery truck before your job starts. The brand choice is based on your attic’s condition, your preference, and what the assembly needs - not what we have a quota to move.
Common Attic Insulation Problems We See in Converse Homes

- Non-IC-rated recessed can lights acting as thermal chimneys. Homes along FM 78 and Kitty Hawk Road were built with standard recessed cans that aren’t airtight. Our blower-door tests consistently flag these as the single largest air-leakage point. 140°F attic air pulls straight into the living space until they’re sealed with rated covers or replaced.
- Original blown fiberglass settled well below rated R-value. The 1993-2012 construction window means an unusually large share of Converse homes hit the same aging point simultaneously. Fiberglass that started at R-30 has compressed and settled to R-19 or lower. The ceiling assembly looks insulated. It isn’t, functionally.
- Unsealed pipe chases from Winter Storm Uri still leaking air. The February 2021 freeze exposed gaps in exterior wall cavities and pipe chases across Converse’s rental stock. Many remain unaddressed because absentee landlords defer maintenance. Top-up insulation alone won’t stop this loss - the chase has to be sealed first.
- Minimal original air-sealing between conditioned and unconditioned space. Builder-grade construction of this era used top plates and drywall as the air barrier. That’s not a barrier. It’s a sieve. Every attic we enter in Converse has measurable leakage at the plate line until we seal it with foam and gasketed covers.

FAQs - Attic Insulation in Converse

Your can lights are probably the non-IC-rated type installed as standard builder practice in 1990s-2000s Converse tract homes, and they were never designed to be airtight. Each unsealed can acts like a small chimney, pulling 140°F+ attic air directly into your conditioned space whenever your HVAC creates negative pressure. We seal them with fire-rated airtight covers or recommend replacement with IC-rated airtight cans before any insulation goes in. Call (830) 402-5240 and we’ll show you the blower-door reading that proves the leak.
Probably not, if it’s the original blown fiberglass. Material from that era in Converse’s builder-grade homes has typically settled from its original R-30 to R-19 or lower, and it was installed with minimal air sealing. We inspect the depth, density, and condition before recommending anything. Sometimes a top-up with air sealing is sufficient. Sometimes removal and replacement is the honest answer. The written price we give you before work starts reflects what we actually find, not what we hope to sell.
Yes. The February 2021 freeze exposed air leaks in pipe chases and exterior wall cavities that many Converse homes still have, particularly in the rental-heavy neighborhoods near JBSA-Randolph where absentee landlords deferred repairs. Those leaks don’t fix themselves. They continue to bleed conditioned air year-round, and they make any attic insulation job incomplete until they’re sealed. We check accessible chases as part of our standard assessment.
The scope is identical - air sealing first, then insulation to code - but the decision-maker is different. We’ve worked with Converse property managers and out-of-state owners who need documented photo records for their files and written warranties that transfer to tenants. The Haven Standard applies regardless of who signs the contract: written price before work, documented record after, 365-Day Done Right Promise. If you’re a tenant, we can inspect and provide a written scope for your landlord’s review.
We primarily install Owens Corning, Johns Manville, and Knauf products in Converse, with GreenFiber cellulose available on request. The specific brand and product depend on your attic’s condition, your preference, and what the assembly needs to perform. We don’t push proprietary products or single-source contracts. Every job gets a written scope that names the material, the R-value target, and the air-sealing steps - before anyone lifts a tool.
Ready for a written price? Call (830) 402-5240. We’ll schedule a visit, run the blower-door test, and show you exactly where your home is losing conditioned air. No work starts without a written price. No job ends without a documented photo record. That’s the Haven Standard.
