Fast, Reliable Blown-In Insulation Across Converse
Blown-in insulation in Converse typically runs $1,800-$4,200 for a full attic retrofit, and most jobs are completed in a single day. We’re familiar with the specific envelope problems in Converse’s 1997-2006 subdivisions - the unsealed attic hatches, the compacted original fiberglass, the top plates that were never caulked - because we work here regularly. Dispatch and scheduling are coordinated from our San Antonio office, but crews serve Converse neighborhoods directly. If your upstairs bedrooms won’t hold temperature or your AC runs nonstop through July, call (830) 420-0953. We’ll send a technician with a blower-door rig and a written price before any work starts.
Why Topside Attic Insulation Converse Is Converse’s Preferred Blown-In Insulation Company
We’ve sealed and insulated attics in Converse Ranch, Meadowbrook, and the older sections off FM 78 - enough to know which builders skipped the hatch weatherstripping and which subdivisions used loose-fill fiberglass that was already below code by the time the first owner moved in. Our Blown-In Insulation team documents every job with before-and-after photos and blower-door readings you can keep for your records.
Converse homeowners leave reviews that mention specific details: the technician who found the uninsulated scuttle hole, the written price that matched the final invoice, the upstairs bedroom that finally held 72°F. We answer calls live, 24/7 - no voicemail loops, no callback windows measured in business days. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. That’s how we’ve operated since 2016, and it’s how we work in Converse today.
Our Blown-In Insulation Services in Converse

Blown-In Cellulose
We blow GreenFiber cellulose in Converse attics where the original fiberglass has settled to 4-6 inches and lost most of its R-value. Cellulose performs better than fiberglass in Converse’s 150°F attic conditions because it resists convection currents and fills irregular joist cavities more completely. A typical full cellulose retrofit in a 1,800-square-foot Converse home runs $2,400-$3,800, including air-sealing and hatch remediation.

Blown-In Fiberglass
For homeowners who prefer fiberglass, we source Owens Corning and Johns Manville loose-fill products with stabilized fiber that resists settling better than the original material installed in most Converse tract homes. We never blow new fiberglass over old without first addressing the air leaks - top plates, can lights, plumbing chases - that make the existing insulation underperform. Most blown fiberglass jobs in Converse fall between $2,200 and $3,600.

Dense-Pack Wall Insulation
Converse’s 1995-2010 slab-on-grade homes often have empty stud cavities or poorly fitted batts in exterior walls. Dense-pack cellulose, blown at 3.5 pounds per cubic foot, fills these cavities without removing drywall - useful in Converse neighborhoods where homeowners want better envelope performance without a full remodel. Wall dense-packing runs $1,200-$2,800 depending on linear footage and access.

Blown-In Top-Up
This is our most common call in Converse: a homeowner has been told to “just add more” insulation, but the real problem is air leakage and a hatch that vents conditioned air straight into the attic. We assess what’s actually there - measure settled depth, check for moisture staining, locate thermal bypasses - then quote a scope that may include partial removal, air-sealing, and a proper top-up to R-38. Top-up jobs with air-sealing in Converse typically range $1,800-$3,200.

AfterTrusted Brands We Service in Converse
We stock Owens Corning, Johns Manville, and Knauf materials for Converse jobs - no proprietary lock-in, no special-order delays. If your home already has one of these products, we can match the type and density for a consistent thermal layer. Our crews carry common densities and blower settings on the truck, so most Converse attics get completed without a return trip for materials.
Common Blown-In Insulation Problems We See in Converse Homes

- Unsealed attic hatches in 1997-2006 builds. Nearly every Converse subdivision from the Randolph AFB boom has a scuttle hole with no insulation or weatherstripping. That 2-square-foot gap acts like an open window into a 150°F attic, destroying the R-value you paid for within a 3-foot radius.
- Compacted original fiberglass below R-38. The blown fiberglass installed in Converse’s build cycle was rarely dense enough to resist settling under two decades of extreme attic heat. We regularly measure 4 inches where 12+ inches are needed for current Climate Zone 2 standards.
- Moisture at the attic floor from Gulf humidity. Converse’s mid-70s dewpoints combined with limited top-plate sealing let humid attic air condense against cooler ceiling drywall. A simple blow-in top-off without vapor management traps that moisture against the structure.
- Top plates and penetrations never sealed. Converse’s fast-built tract homes skipped the caulk and foam at wall top plates, can lights, and plumbing chases. Conditioned air leaks upward continuously, carrying humidity and wasting the insulation layer’s effective performance.
Pricing for Blown-In Insulation in Converse, TX
Most full attic retrofits in Converse run $2,200-$4,200, with blown-in top-ups starting around $1,800 when air-sealing and hatch remediation are included. Dense-pack wall work adds $1,200-$2,800. What moves the number: attic square footage, current insulation depth and condition, accessibility, and whether the hatch needs rebuilding with proper insulation and weatherstripping - nearly universal in Converse homes from the 1997-2006 build wave.

FAQs - Blown-In Insulation in Converse

Because the new insulation probably went over an unsealed attic hatch and air-leaky top plates, so conditioned air escapes faster than the added R-value can retain it. We were called to a two-story in the Converse Ranch area where the upstairs bedrooms ran 6-8°F hotter than downstairs every afternoon; the original blown insulation had settled to about 4 inches with an R-value barely into the teens. After air-sealing top plates, weatherstripping and insulating the unsealed attic hatch, and blowing GreenFiber cellulose up to R-38, the upstairs supply-air split closed and the second floor finally held setpoint without the AC running nonstop. Call (830) 420-0953 for a free assessment - estimates are free.
Yes. In Converse’s 1997-2006 Randolph AFB tract-home wave, attic access hatches were installed with zero insulation or weatherstripping in nearly every subdivision, and those unsealed scuttle holes vent conditioned air straight into a 150°F attic all summer. A 2-square-foot unsealed hatch can leak as much air as a 6-inch hole in your wall. We include hatch remediation - insulation, weatherstripping, and proper closure - in any Converse scope where it’s needed. Call (830) 420-0953 and we’ll check yours.
Only after we verify the existing material is dry, uncontaminated, and the air leaks are sealed. Gulf-humidity dewpoints in the mid-70s combined with limited top-plate air-sealing in Converse homes let moist attic air condense at the attic floor. Burying wet or compacted fiberglass traps moisture against the ceiling drywall. We probe for depth, check for staining, and run moisture readings before recommending overlay versus partial removal. Call (830) 420-0953 for an exact scope - estimates are free.
IECC Climate Zone 2 calls for R-38 to R-49 in attics, and Converse’s five-plus months of cooling load with frequent 100°F days puts you at the higher end of that range. Most original Converse attics were built to R-30 or less, and settling has dropped effective performance to R-15 or below. We blow to R-38 minimum, measured and verified, with documentation you keep. Call (830) 420-0953 for a written quote.
Yes, especially given the high concentration of military renters and frequent PCS-driven turnover in Converse, where many attics have never been audited or upgraded. A documented retrofit with before-and-after blower-door numbers adds demonstrable efficiency data for resale or lease renewal, and the 365-Day Done Right Promise transfers with the property records we provide. The energy savings typically recover investment in 3-5 years in Converse’s cooling-dominated climate. Call (830) 420-0953 - we’ll run the numbers with your specific attic condition.
