Fast, Reliable Attic Insulation Across Converse
Most attic insulation jobs in Converse run $1,800-$4,500 depending on square footage and whether we’re topping up existing material or stripping degraded batts and starting fresh. We’re typically on-site in Converse within 24-48 hours of your call, and we bring the same blower-door rig and written-price protocol we use on every job. If you’re in a 1960s ranch near JBSA-Randolph or a 2000s subdivision off FM 78, the attic conditions we find are usually predictable - and so is our process. Call (830) 529-7780 to schedule a free estimate with a written price before any work starts.
Why Topside Attic Insulation Boerne Is Converse’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our retrofit work comes from Converse’s northeast Bexar County neighborhoods. The pattern is consistent: homeowners who bought a ranch near the base perimeter or a vinyl-sided subdivision built during the 2000s boom call us after a summer electric bill cracks $400 or a back bedroom won’t hold temperature.
Our crews serve Converse from our San Antonio dispatch office, which keeps response times short and material stock current. Reviews from Converse customers tend to mention two things - the blower-door numbers we leave behind and the photo record they can scroll through on their phone. We don’t ask you to trust our enthusiasm. We document the work.
Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. Every job begins with a written price and ends with a Documented Photo Record. No exceptions.
Our Attic Insulation Services in Converse
Blown-In Attic Insulation
We blow loose-fill cellulose and fiberglass across Converse attics where the existing material is thin, uneven, or compromised by air movement. In the 2000s-2010s subdivisions near Converse North and Woodlake, we regularly find minimum-code blown fiberglass that settled to R-20 or below, with unsealed top plates letting 150°F attic air wash through the insulation layer. Our Attic Insulation crew air-seals first, then blows to the depth that hits your target R-value - usually R-38 to R-49 for Climate Zone 2.
Attic Batt Insulation
New batt installs are rare in Converse unless we’re working a finished attic conversion or a specific joist-bay configuration where loose-fill won’t perform. When we do install batts, we use Owens Corning or Johns Manville products, cut to fit around obstructions, and never compress them into place - compressed batt loses R-value fast. This matters in the older ranch homes near Gibbs Sprawl Road, where irregular framing and decades of DIY patches have left bays of varying widths.
Attic Insulation Top-Up
A top-up makes sense when your existing insulation is in decent shape, just thin. In Converse, that’s occasionally true in the newer builds east of Loop 1604, but it’s rarely the right call for the 1950s-1970s stock near JBSA-Randolph. If the original batts are compressed to R-6 by inspection foot traffic, blowing new material on top traps the degraded layer underneath and hides the problem. We’ll tell you when a top-up is appropriate and when it isn’t - and we’ll show you the photos so you can see why.
Attic Insulation Replacement
This is the most common service we perform in Converse. We strip the old material, air-seal the attic floor - top plates, can lights, penetrations, the chimney chase - then install new insulation to a specified depth. On a 1968 slab-on-grade ranch just south of the JBSA-Randolph perimeter in Converse, our tech pulled up the access panel and found the original Owens Corning fiberglass batts crushed to barely 1.5 inches along the furnace inspection trail, with the rest of the attic sitting at roughly R-8. We ran attic baffles at the soffits, air-sealed the top plates and can lights, then blew in GreenFiber loose-fill to bring the whole field up to R-38, and the homeowner reported the back bedrooms holding temperature through the first August after the work.
Attic Baffles & Ventilation Prep
Converse attics hit 150°F in summer. Without proper soffit-to-ridge airflow, that heat radiates straight through the insulation into your living space. We install baffles - cardboard or foam channels that keep insulation from blocking soffit vents - on every replacement job where the roof has vented soffits. In the low-pitch ranches common west of FM 78, baffles are essential; the shallow roof deck leaves little room for error, and blocked ventilation turns the attic into a convection oven.

Trusted Brands We Service in Converse
We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, among others. No proprietary lock-in - we specify what performs for your attic’s conditions. For Converse homeowners, that usually means GreenFiber cellulose or Owens Corning blown fiberglass for loose-fill jobs, with baffles and air-sealing details from standard building-supply stock. We keep common depths and densities on hand so we’re not waiting on a freight delivery while your attic sits open.
Common Attic Insulation Problems We See in Converse Homes
- Inspection-trail compression in base-adjacent ranches. Contractors working the streets immediately west and south of JBSA-Randolph frequently find attics where the original 1960s fiberglass batts have compressed to less than 2 inches due to decades of foot traffic from military-required annual HVAC inspections - a base-adjacent maintenance pattern that’s left insulation performing at R-6 or below in homes the owners assume are adequately insulated. The darkened, trampled runs are usually visible from the access hatch.
- Settled blown fiberglass in 2000s subdivisions. Minimum-code blown fiberglass in 2000s-2010s vinyl-sided subdivisions settled unevenly and, with unsealed top plates and recessed can gaps, gets bypassed by 150°F attic air that short-circuits the R-value. Homeowners in Converse neighborhoods like Woodlake and Converse North call us when the second floor won’t cool below 78°F despite a new AC unit.
- Post-Uri moisture damage. The February 2021 Winter Storm Uri revealed severe under-insulation around water lines and in unconditioned spaces across Bexar County’s northeast suburbs. We still find batt staining and compressed, moisture-degraded fiberglass in Converse attics where pipes sweated through the freeze and the insulation never recovered.
- Missing radiant-barrier pairing. Converse sits in IECC Climate Zone 2 (hot-humid), where summer attic temperatures routinely exceed 150°F and outdoor temps push 100°F for weeks at a stretch. Fiberglass alone isn’t enough. We regularly recommend radiant-barrier retrofit - foil-faced sheeting or roof-deck spray - as part of a complete attic system, especially on west-facing pitches that cook all afternoon.

What moves you within these ranges: attic square footage, accessibility, whether we’re removing old material, and the extent of air-sealing required. A 1,400-square-foot ranch with compressed 1960s batts and no prior air sealing runs toward the higher end. A 2015 build with thin but intact blown fiberglass and accessible soffits sits lower. We provide a written price before any work starts - Haven Standard Clause 1 - and a free second opinion on any competing written estimate. Call (830) 529-7780 for your exact number.

FAQs - Attic Insulation in Converse
Because the original fiberglass batts are compressed to R-6 or below by decades of annual HVAC inspection foot traffic, and blowing new material on top traps that degraded layer underneath. We strip, air-seal, and start fresh so the new insulation actually performs. Call (830) 529-7780 for a free estimate - we’ll show you photos of what we find.
Yes. Sustained attic temperatures above 150°F accelerate binder breakdown and cause fiberglass to slump and lose loft. In Converse, batts installed in the 1960s-1980s are often performing at half their labeled R-value or less. We measure what you actually have, not what the mill stamp says.
Uri exposed how many northeast Bexar County homes had under-insulated water lines and unconditioned attic spaces that couldn’t maintain temperature during the freeze. Post-storm, we’re called more often for pipe-bay insulation and whole-attic replacement together - homeowners don’t want a repeat. The 2021 event also made radiant-barrier pairing more common, since the same attics that failed in cold were already failing in summer heat.
Not obsolete, but usually underperforming. Minimum-code blown fiberglass from that era was typically R-30 or less, and it settles. With updated Texas energy-efficiency expectations and the air-sealing gaps common in production builds, most 2000s Converse attics benefit from top-up or replacement to R-38+ with proper air sealing. We can tell you in 20 minutes on-site.
We measure depth, density, and condition during our initial inspection, then photograph everything. If the batts are compressed, stained, or displaced - common near JBSA-Randolph - we recommend replacement. If they’re intact and just thin, a top-up may work. You’ll see the evidence before we write the price.
