Trusted Wall Insulation for Converse Homeowners
Our Wall Insulation cost guide shows Converse projects typically run $2,800-$7,500 for a whole-home retrofit, with most jobs completed in one to two days. We’re Topside Attic Insulation Converse, and we’ve sealed and insulated more than 9,000 homes since 2016 under The Haven Standard. Every wall insulation job starts with a written price and ends with a documented photo record, plus before-and-after blower-door numbers when air sealing is part of the scope. Call (830) 420-0953 and a live person will answer, 24/7.
Converse sits on the edge of Bexar County’s blackland prairie clay, and the homes built here between 1995 and 2015, especially in neighborhoods like Converse Heights, Woodlake, and The Meadows, were often framed with 2×4 walls and minimal cavity fill. That construction era predates the 2012 IECC code changes that mandated higher R-values, which means thousands of local walls are under-insulated by modern standards. We’ve measured blower-door readings above 4,500 CFM50 in these homes, double what a sealed, insulated envelope should hold. When summer temperatures hit 102°F for weeks straight, that uncontrolled air exchange forces your HVAC to run continuously and still leaves rooms uncomfortable, which is why many homeowners search for Wall Insulation in Converse.
Our crews work throughout Converse and the 78109 zip, with same-day appointments available most weekdays. We don’t subcontract wall insulation work. Our technicians are background-checked, uniformed, and arrive with a written scope already in hand.
What Our Wall Insulation Service Includes
Injection Foam Wall Insulation
Injection foam is a water-based resin that expands to fill wall cavities through holes drilled from the exterior, hardening into a dense, air-blocking matrix. You need this when your walls are empty or contain degraded fiberglass batts that have settled or been compromised by moisture, which we find regularly in 1980s and 1990s Converse subdivisions where poly vapor barriers failed. We drill 5/8-inch holes at stud-bay intervals, inject the foam under controlled pressure to avoid bowing drywall, then seal each penetration with color-matched plugs. Every injection job includes a blower-door test before and after so you see the air-leakage reduction in CFM50.

Drill & Fill Wall Insulation
Drill and fill uses loose-fill fiberglass or cellulose blown into wall cavities through exterior or interior access points, a cost-effective retrofit when the wall sheathing is intact but the cavity is empty or underfilled. We recommend this for Converse homes with aluminum or vinyl siding that can be removed and replaced cleanly, particularly in the older ranch-style homes north of FM 78 where wall cavities were often left with R-11 batts or nothing at all. Our crews use infrared cameras during the fill to verify complete cavity coverage and identify any hidden blocking or fire stops that would create voids. You receive photos of the thermal imaging and the filled cavities as part of your Documented Photo Record.

Exterior Wall Insulation
Exterior wall insulation adds a continuous thermal layer outside the existing wall sheathing, typically with rigid foam board or mineral wool, before new cladding goes on. This is the right approach when you’re already residing your Converse home, or when interior disruption must be minimized in finished spaces. We see this most often in the two-story homes near Rolling Meadows, where homeowners want to eliminate thermal bridging through studs without tearing out interior drywall. Our crews detail all seams with tape and sealant, integrate flashing at windows and doors, and provide a written moisture-management plan because exterior foam changes how your walls dry. The Haven Standard requires that we document the assembly’s permeability rating and share it with you before work starts.

Interior Wall Soundproofing
Interior wall soundproofing uses dense-packed cellulose, mineral wool batts, or mass-loaded vinyl to reduce airborne and impact noise transmission between rooms. Homeowners in Converse call us for this when a home office, nursery, or media room shares a wall with a high-traffic area, or when multi-generational living arrangements need acoustic privacy. We typically work with Owens Corning Thermafiber or Rockwool Safe’n’Sound in these applications, installed within existing stud bays or as part of a resilient-channel decoupling system for maximum performance. Every soundproofing quote includes an STC (Sound Transmission Class) target based on your specific noise concern, not a generic “quieter” promise.

Brands We Service for Wall Insulation

We source and install materials from Owens Corning, Johns Manville, Knauf, and other leading manufacturers, with no proprietary lock-in that limits your options. Our crews have completed hundreds of wall insulation jobs using Owens Corning fiberglass systems, including their PROPINK L77 loose-fill for drill-and-fill retrofits and FOAMULAR rigid board for exterior applications. We know the density requirements and installation tolerances for each product line, and we don’t substitute materials mid-job without written approval.
We’ve also worked extensively with Johns Manville blown-in fiberglass and Knauf Jet Stream ULTRA for high-density wall cavity fills. Whether your project specifies a particular brand for warranty compatibility, energy rebate requirements, or personal preference, we can source and install it correctly. If you have GreenFiber cellulose, Rockwool mineral wool, or any other make already in your walls, we assess its condition and integrate new material properly rather than layering incompatible products.
Before
AfterSigns You Need Wall Insulation Right Now
- Rooms that stay hot in summer and cold in winter despite your HVAC running constantly. This is often the first symptom Converse homeowners notice, especially in south- and west-facing rooms where solar gain compounds the effect of uninsulated walls. The thermal mass of your drywall becomes a heat sink, radiating discomfort long after the sun has moved. A blower-door test can isolate whether the problem is wall leakage, attic bypass, or both.
- Energy bills that spike 30% or more during peak summer months compared to similarly sized homes. We’ve reviewed utility bills from Converse customers whose July and August cooling costs exceeded $400 while neighbors in comparable homes paid under $250. When the attic is already insulated, the walls are the next largest surface area of uncontrolled heat transfer. Our home energy audits include wall thermal imaging to quantify the loss.
- Exterior walls that feel hot or cold to the touch, or interior wall outlets that draft air. In a properly insulated and sealed wall, the interior surface temperature should stay within a few degrees of room temperature. If your walls feel like the outside, or if you feel air movement around electrical boxes, the cavity is either empty or the air barrier has failed. We find this frequently in homes where original builders used cardboard baffles instead of proper blocking.
- Moisture stains, mold odor, or peeling paint on exterior walls. Uninsulated walls create temperature differentials that cause condensation on the interior surface, especially in Converse’s humid shoulder seasons when dew points rise. We’ve remediated wall cavities in the Green Valley neighborhood where fiberglass batts became moisture reservoirs, compressing and degrading while promoting mold growth. Insulation without air sealing makes this worse, which is why we seal before we insulate, always.
- Your home was built before 2012 and has never had wall insulation upgraded. Pre-2012 construction in Bexar County and surrounding areas typically used R-11 or R-13 cavity fill, well below current code minimums. If you’ve owned since 2015 or earlier and haven’t addressed walls, you’re living with performance standards from two decades ago. Our free estimates include a code-comparison analysis so you understand what you’re missing.
Our Wall Insulation Process - Step by Step

- 1
On-site assessment and thermal imaging. We arrive at your Converse home with a written appointment time and a text notification when the technician is en route. Our assessment includes infrared scanning of all exterior walls to identify voids, thermal bridging, and moisture anomalies. We also run a blower-door test if air sealing is part of the scope, establishing your baseline CFM50 leakage rate.
- 2
Written price and scope delivery. Before any work starts, you receive a flat-price proposal with the Haven Standard Clause 1 guarantee: written scope, written warranty, and documented photo record specified in advance. No hourly rates, no material-upcharge surprises. We also offer a Free Second Opinion on any competing written estimate you bring us.
- 3
Air sealing preparation. For cavity-fill jobs, we seal top plates, electrical penetrations, can-light housings, and any other bypasses before insulation enters the wall. This is non-negotiable at Topside Attic Insulation Converse. Blowing insulation over an unsealed cavity is like pouring water into a bucket with holes, and we won’t do it.
- 4
Insulation installation with real-time verification. Our crews install your specified material to manufacturer density and coverage requirements, using infrared cameras during the process to confirm complete fill. For injection foam, we monitor expansion pressure to prevent drywall distortion. For exterior rigid foam, we tape all seams and integrate proper drainage planes.
- 5
Post-installation testing and documentation. We rerun the blower-door test on air-sealing jobs and provide the before-and-after CFM50 comparison. You receive a complete Documented Photo Record of the work, including thermal images, cavity-fill verification, and any relevant code-compliance notes. The 365-Day Done Right Promise is activated in writing before we leave.
How Much Does Wall Insulation Cost in Converse?
A typical drill-and-fill job for a 1,800-square-foot home runs $3,200-$5,400, while injection foam for the same footprint typically ranges from $4,500-$7,200, similar to Wall Insulation - Universal City pricing. Exterior wall insulation with rigid foam board, including new siding prep, generally starts at $8,500 and scales with wall area and cladding choice. Interior soundproofing of a single room averages $1,800-$3,400 depending on whether we’re working within existing drywall or installing resilient channels.
Several factors move these numbers. Wall cavity depth is the main variable: 2×4 construction limits R-value potential compared to 2×6 framing, and some Converse homes built in the 1970s have irregular stud spacing that complicates installation. Exterior accessibility matters too. Homes with brick veneer require interior access or specialized drilling, which adds labor. The condition of existing insulation affects whether we can dense-pack over it or must remove degraded material first.
To avoid overpaying, get any estimate in writing with line-item material specifications and coverage rates. Some Converse contractors quote by the square foot of wall area without stating the installed R-value or density, which lets them underbid with thin coverage. Our written quotes specify the product, the target density, and the expected performance outcome. We also don’t require a deposit before work begins; payment is due at completion, after you’ve reviewed your documentation.

Frequently Asked Questions - Wall Insulation in Converse

Wall insulation is material installed within or on the structural cavities of exterior walls to slow heat transfer and reduce air leakage. In Converse’s climate, it keeps conditioned air inside during 100°F summer stretches and prevents heat loss during winter cold snaps, just as Wall Insulation - Schertz does for homes to the north. We install fiberglass, cellulose, foam, or mineral wool systems depending on your wall construction and performance goals, always sealing air leaks first.
Most residential wall insulation jobs in Converse are completed in one to two working days. A single-room soundproofing project may finish in four to six hours, while a whole-home exterior rigid-foam application with residing can extend to four or five days. We specify the timeline in your written scope before work starts, and we don’t leave mid-job to chase other projects.
Drill-and-fill jobs for typical Converse homes run $3,200-$5,400; injection foam ranges $4,500-$7,200; exterior rigid-foam systems start around $8,500.
