Insulation in Converse, TX
Crawl space encapsulation and vapor barrier installation in Converse typically runs $2,800-$5,500 for a standard slab-on-grade home, with most jobs completed in one to two days. Converse’s 1980s-2000s military-rental housing stock sits on expansive clay soils with minimal moisture protection, making unsealed crawl spaces a constant source of humidity, mold risk, and wasted cooling dollars. We dispatch crews from our San Antonio office and carry vapor barrier materials, dehumidifiers, and sealants stocked for Converse’s specific foundation types. Call (830) 243-6352 for a written price before any work starts.
Why Converse Homes Are Different
Converse is a bedroom community built largely around Joint Base San Antonio-Randolph, meaning its housing stock is dominated by 1980s-2000s tract homes constructed quickly to house a high-turnover military population. These homes received minimal builder-grade insulation and have rarely been upgraded because military renters and short-term owners don’t invest in energy improvements. This creates a uniquely dense concentration of aging, under-insulated homes with original R-19 attics and virtually no air sealing.
The heavy concentration of military rental properties means many homes have had attic insulation disturbed or compressed by repeated HVAC service access without any remediation. Technicians working the JBSA-Randolph corridor frequently find attic insulation that looks intact from the hatch but has been shoved aside, compressed, or torn open around ductwork by years of rotating HVAC crews. The effective R-value ends up far below what even the original thin install provided, and it’s a consistent pattern across the military-rental streets east of the base.
Converse sits in the northeastern San Antonio metro where summer highs routinely exceed 98-102°F, driving unconditioned attic temperatures past 150°F and making under-insulated 1980s tract homes extraordinarily expensive to cool. Gulf of Mexico moisture also creates vapor drive conditions that can cause fiberglass batts to lose effective R-value through moisture absorption if not properly air-sealed.
Our Main Converse Services
Converse homeowners call us most often for attic work and spray foam upgrades. These three services have dedicated Converse pages with deeper detail:
Attic Insulation in Converse
Attic insulation in Converse means dealing with vented attics, original R-19 batts, and the compressed, displaced insulation we find around ductwork in military-rental properties. We remove what’s there, air seal the floor, then install new material to current Texas energy code levels. Every attic job includes a written scope and documented photo record. Attic Insulation in Converse covers material options, pricing, and what the blower-door test will show you.

Spray Foam Insulation in Converse
Spray foam insulation in Converse works best for open attics, bonus rooms over garages, and the rim joists in homes with crawl space access. We use open-cell and closed-cell foams from Owens Corning and Demilec, specified to the job, not pushed as a default. Converse’s extreme attic temperatures make spray foam’s air-sealing performance particularly valuable. Spray Foam Insulation in Converse breaks down cost factors and where it does and doesn’t make sense.

Blown-In Insulation in Converse
Blown-in insulation in Converse is our most common retrofit for the original R-19 batt homes east of JBSA-Randolph. We blow fiberglass or cellulose over a fully sealed attic floor, never over unsealed penetrations. The material we select depends on your attic’s condition and your budget. Blown-In Insulation in Converse explains the blower-door-verified results we’ve documented in this market.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Converse

Converse’s slab-on-grade tract homes from the 1980s-2000s were built with minimal ground moisture protection, and the few homes with crawl space access sit on expansive clay soils that wick water year-round. Without encapsulation, that moisture migrates into floor systems, degrades fiberglass insulation, and creates the musty, humid conditions that force air conditioners to run longer. We provide Crawl Space Encapsulation & Vapor Barrier as a complete system, not a plastic-sheet shortcut.
Crawl Space Vapor Barrier
Signs you need it
Your floors feel cold and damp in summer, you smell mustiness from below, or you find condensation on ductwork in the crawl space.
What it costs in Converse
A 6-mil to 20-mil vapor barrier installed over bare earth in a Converse crawl space typically runs $1,200-$2,800 depending on square footage and seam-sealing requirements.
How we do it
We remove debris, grade the floor, lay overlapping polyethylene sheeting with sealed seams, and mechanically fasten it to walls and piers so groundwater vapor cannot reach the structure.
Crawl Space Encapsulation
Signs you need it
You have standing water after rain, visible mold on floor joists, or energy bills that spike despite recent HVAC service.
What it costs in Converse
Full encapsulation with sealed vapor barrier, wall insulation, and mechanical dehumidification in a Converse crawl space generally ranges from $4,500-$8,500.
How we do it
We seal all vents, install a continuous vapor barrier on floors and walls, insulate rim joists with rigid foam, and add a condensate-pumped dehumidifier sized to the space.
What Crawl Space Encapsulation & Vapor Barrier Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Vapor barrier (6-20 mil, earth only) | $1,200 - $2,800 |
| Partial encapsulation (barrier + sealing) | $2,800 - $4,500 |
| Full encapsulation with dehumidifier | $4,500 - $8,500 |
How long does crawl space encapsulation take in Converse?
Most Converse crawl space jobs finish in one to two days; full encapsulation with dehumidifier installation may extend to three days if electrical work is needed. We give you a written schedule with the price.
Will encapsulation lower my cooling bills?
Yes, typically 10-20% in Converse homes where the crawl space was previously vented and humid, because the air conditioner stops fighting moisture load from below. We document pre- and post-conditions with photos.
Radiant Barrier Installation in Converse

Converse attics hit 150°F regularly in summer, and the original R-19 batts in most local homes were never designed to handle that radiant heat load. A radiant barrier reflects infrared energy back toward the roof deck rather than letting it saturate insulation and radiate into living spaces below. In the JBSA-Randolph corridor, we’ve measured attic floor temperatures drop 20-30°F after proper radiant barrier installation, with corresponding reductions in AC runtime. Radiant Barrier Installation is one of the few upgrades that pays back fastest in this specific climate.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 p.m., your AC runs continuously on summer afternoons, or your roof decking is visible and uncoated from inside the attic.
What it costs in Converse
Radiant barrier foil stapled to attic rafters in a typical 1,800-2,400 square foot Converse home runs $1,100-$2,400 including material and labor.
How we do it
We install perforated aluminum foil across rafter bays, leaving proper ventilation channels, and verify with infrared imaging that the reflective surface faces the air gap correctly.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the radiant barrier integrated at the deck level rather than retrofitting foil later.
What it costs in Converse
Radiant barrier roof decking or spray-applied radiant coating during reroof in Converse typically adds $1,800-$3,500 to the roofing project.
How we do it
We coordinate with your roofing contractor to install OSB with factory-applied radiant foil or spray a low-emissivity coating directly to the deck before shingles go on.
What Radiant Barrier Installation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic radiant barrier foil (retrofit) | $1,100 - $2,400 |
| Radiant barrier roof deck (with reroof) | $1,800 - $3,500 |
| Radiant barrier with attic air sealing package | $2,400 - $4,200 |
Does radiant barrier work with my existing insulation?
Yes, it works best when paired with adequate insulation; we won’t install radiant barrier over compressed or displaced batts without addressing the underlying insulation first. The combination is what produces the measured result.
How much can radiant barrier reduce my attic temperature?
We typically measure 20-30°F reduction at the attic floor in Converse homes, though results vary with roof color, ventilation, and existing insulation condition. We show you the thermal images.
Insulation Removal & Replacement in Converse

The military-rental cycle in Converse means attics have seen decades of HVAC technicians, cable installers, and homeowners trampling, compressing, and displacing original insulation without any remediation. What looks like R-19 from the hatch often performs like R-11 or worse by the time we open it up. We remove the compromised material, sanitize the deck, and install new insulation to a verified depth. Insulation Removal & Replacement is not a job we shortcut; the old material comes out completely before anything new goes in.
Attic Insulation Removal
Signs you need it
Your insulation is compressed below the joist tops, stained from roof leaks, or scattered in piles where work was performed.
What it costs in Converse
Removing old fiberglass or cellulose from a standard Converse attic runs $1.50-$3.00 per square foot, or roughly $1,200-$2,800 for most homes in this market.
How we do it
We use commercial vacuums with HEPA filtration, bag the material at the machine, and haul it off so no debris enters your living space.
Contaminated Insulation Removal
Signs you need it
You’ve had rodent activity, visible mold growth, or water damage that saturated the insulation and created odor.
What it costs in Converse
Contaminated removal with sanitizing and deodorizing in Converse typically ranges from $2,200-$4,500 depending on contamination extent and attic square footage.
How we do it
We remove all affected material, apply enzymatic sanitizer to the deck and framing, then verify with moisture meters before any new insulation is installed.
What Insulation Removal & Replacement Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Standard attic insulation removal | $1,200 - $2,800 |
| Contaminated insulation removal + sanitizing | $2,200 - $4,500 |
| Removal + replacement with new blown-in | $3,500 - $6,500 |
Do I have to leave during insulation removal?
No, though we recommend avoiding the attic access area during vacuuming; our equipment vents outside and we seal the hatch during work. Most Converse homeowners stay in the house.
How do I know if my insulation is contaminated?
Dark staining, urine odor, or visible droppings indicate rodent contamination; musty smell or visible mold suggests moisture damage. We inspect and photograph everything before quoting removal.
Attic Air Sealing in Converse

Converse’s 1980s-2000s tract homes were built with minimal attention to the building envelope; top plates, can lights, and duct boots were left open to the attic, creating direct paths for 150°F air to enter conditioned space. Air sealing is the hard prerequisite we never skip. We complete Attic Air Sealing before adding any insulation, and we prove the result with before-and-after blower-door numbers on every applicable job.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from outlets on exterior walls, see dusty streaks around ceiling fixtures, or notice your HVAC struggles to maintain temperature on windy days.
What it costs in Converse
Sealing top plates, wire penetrations, and plumbing stacks in a typical Converse attic runs $800-$1,800 as a standalone service, or it’s built into our insulation packages.
How we do it
We use expanding foam, fire-rated caulk, and rigid blocking to seal every gap where conditioned space communicates with the attic, then verify with blower-door testing.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in wind, you feel hot air dropping from ceiling vents in summer, or your ducts show dust accumulation on the exterior.
What it costs in Converse
Sealing can lights with rated covers and mastic-sealing duct boots in Converse typically costs $600-$1,400 depending on fixture count and duct configuration.
How we do it
We install fire-rated enclosures over non-IC can lights, seal duct boots with mastic and mesh, and pressure-test the duct system where accessible.
What Attic Air Sealing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Top plate & penetration sealing | $800 - $1,800 |
| Can light & duct boot sealing | $600 - $1,400 |
| Full attic air sealing (comprehensive) | $1,800 - $3,200 |
What is a blower-door test?
A blower-door test is a pressurization reading that shows, in one number, how much air your building envelope is losing; we run it before and after sealing so you see the CFM50 reduction you paid for.
Can air sealing alone reduce my energy bills?
Yes, typically 10-15% in Converse homes with significant leakage, though we recommend pairing it with insulation replacement for the full performance change. We quote both options.
Wall Insulation in Converse

The 1980s-2000s tract homes dominating Converse were built with 2×4 walls and minimal cavity insulation, often with gaps and compression around electrical boxes and plumbing. Exterior walls in these homes regularly test with effective R-values below 10. We retrofit wall insulation without tearing out drywall, using injection methods that fill the cavity completely. Wall Insulation in Converse is particularly valuable for rooms with west-facing walls that bake in afternoon sun.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, rooms with west or south exposure are unusable in afternoons, or your siding was removed for repair.
What it costs in Converse
Injecting foam into existing 2×4 walls in a Converse home runs $3.50-$6.00 per square foot of wall area, or roughly $2,800-$5,500 for a typical 1,500-square-foot home.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud spacing, inject slow-rise foam that fills without bowing, then patch and match the surface.
Drill & Fill Wall Insulation
Signs you need it
Your walls have no insulation or settled batt that leaves gaps at the top and bottom of cavities, or you’re remodeling and have wall access.
What it costs in Converse
Drill-and-fill with dense-pack cellulose in Converse walls typically costs $2.50-$4.50 per square foot, making it a cost-effective retrofit for the original batt homes near JBSA-Randolph.
How we do it
We remove a row of siding or drill through drywall, blow cellulose to 3.5 pounds per cubic foot density to prevent settling, then seal and finish.
What Wall Insulation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Injection foam (2×4 walls) | $2,800 - $5,500 (typical home) |
| Dense-pack cellulose drill & fill | $2,000 - $4,200 (typical home) |
| Exterior wall insulation with siding off | $3,500 - $6,500 (typical home) |
Will injection foam damage my walls?
No, we use slow-rise formulations and controlled pressure; in 9,000+ homes we’ve never bowed studs or cracked drywall. We check cavity depth and obstructions before injecting.
Can you insulate walls without removing drywall?
Yes, we access cavities through exterior siding or small interior patches; the holes are 5/8 inch and we match texture and paint. Most Converse homeowners can’t locate our patches afterward.
Attic Cleaning & Rodent Proofing in Converse

The mature trees and established neighborhoods around Converse create active squirrel, rat, and mouse pathways onto roofs, and the vented attics with minimal sealing in local tract homes are easy entry points. Once inside, rodents compress insulation, contaminate it with urine and droppings, and create fire hazards by chewing wiring. We clean what they’ve damaged and seal how they got in. Attic Cleaning & Rodent Proofing includes the documentation your insurance company will want to see.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia or mustiness from the attic, see dark staining on insulation or decking, or have found dead rodents or nesting material.
What it costs in Converse
Attic sanitizing and decontamination in Converse runs $1,800-$3,500 for a standard attic, including removal of contaminated material, enzymatic treatment, and odor neutralization.
How we do it
We remove all contaminated insulation and debris, apply commercial-grade enzymatic sanitizer to break down organic matter, then treat with odor neutralizer before any new work begins.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find droppings in the attic, or see chew marks on fascia boards, soffits, or roof vents.
What it costs in Converse
Rodent proofing and exclusion for a typical Converse home ranges from $900-$2,200 depending on entry point count, roof complexity, and whether one-way doors are needed.
How we do it
We inspect the roofline, soffits, vents, and foundation, seal all entry points with rodent-proof materials, and install barriers where gnawing is likely to recur.
What Attic Cleaning & Rodent Proofing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic sanitizing & decontamination | $1,800 - $3,500 |
| Rodent proofing & exclusion | $900 - $2,200 |
| Full attic restoration (cleaning + proofing + re-insulation) | $4,500 - $8,500 |
How do I know if rodents are in my attic?
Nocturnal scratching, visible droppings, or compressed insulation trails are clear signs; we also find gnawed wiring and stored debris from nesting. We photograph everything during inspection.
Will rodents return after you seal the attic?
Not through the same entry points; our exclusion work carries the 365-Day Done Right Promise, and we use materials rodents cannot chew through. We also identify and address attractants like overhanging branches.
Home Energy Audit in Converse

A home energy audit in Converse reveals what the eye cannot see: where 150°F attic air is entering your living space, how much conditioned air your ducts are losing to the attic, and whether your insulation’s effective R-value matches what’s on the label. For the 1980s-2000s tract homes that dominate this market, the gap between assumed and actual performance is usually significant. We run Home Energy Audit visits with blower-door testing, thermal imaging, and documented findings you can use to prioritize work or compare quotes.
Blower Door Test
Signs you need it
Your energy bills are rising without rate increases, rooms have uneven temperatures, or you’re considering insulation work and want a baseline measurement.
What it costs in Converse
A standalone blower-door test with written report in Converse runs $350-$600; it’s included at no charge when you proceed with recommended work.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage and identify dominant leak paths.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation behind walls, want to verify insulation was installed correctly, or need documentation for an insurance or warranty claim.
What it costs in Converse
Thermal imaging as part of a full energy audit in Converse typically runs $250-$450 when booked separately, or it’s bundled with the blower-door test.
How we do it
We use FLIR cameras to map surface temperatures across walls, ceilings, and ductwork, interpreting patterns to locate missing insulation, air leaks, and moisture intrusion.
What Home Energy Audit Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Blower-door test with written report | $350 - $600 |
| Thermal imaging inspection | $250 - $450 |
| Full home energy audit (comprehensive) | $450 - $850 |
What does a home energy audit include?
Our Converse audits include blower-door testing, thermal imaging, insulation inspection, and duct leakage testing where accessible; you receive a written report with prioritized recommendations and photos.
Can I use the audit report to get other quotes?
Yes, the report is yours; we encourage you to get a free second opinion on any competing quote using our findings. The documentation belongs to you.
