Insulation in Converse, TX
Crawl space encapsulation and vapor barrier installation in Converse typically runs $2,800-$5,500 for a standard ranch home, with most jobs completed in one to two days. The combination of slab-on-grade construction, high water tables in parts of Bexar County, and decades of minimal maintenance on original vapor barriers means Converse crawl spaces often show moisture readings that would trigger mold risk in any climate, let alone ours. If you’re seeing musty odors from floor registers or soft spots near bathroom plumbing, call (830) 529-7780. We’ll give you a written price before any work starts, and every encapsulation job leaves with a Documented Photo Record and a 365-Day Done Right Promise under Haven Standard.
Why Converse Homes Are Different
Converse grew as off-base housing for Randolph AFB personnel, and the waves of postwar and Cold War-era tract construction produced a concentrated stock of low-pitch ranch homes built to minimal insulation standards. The high military-transient turnover rate historically discouraged owners from investing in upgrades, leaving a disproportionately large share of homes still running on degraded or sub-R-11 attic insulation that cannot cope with South Texas cooling loads.
The housing stock splits into two clear bands: 1950s-1970s slab-on-grade ranches near JBSA-Randolph with thin original fiberglass batts that have settled and moisture-degraded, and 2000s-2010s vinyl-sided subdivisions where builders used minimum-code blown fiberglass around R-30 that now falls short of updated Texas energy-efficiency expectations. Both eras have attic air-sealing gaps that compound the shortfall. Summer attic temperatures here routinely exceed 150°F, and the February 2021 Winter Storm Uri revealed severe under-insulation around water lines that still drives retrofit demand in northeast Bexar County neighborhoods.
Contractors working streets immediately west and south of the base frequently find attics where original 1960s fiberglass batts have compressed to less than 2 inches due to decades of foot traffic from military-required annual HVAC inspections. Base-adjacent maintenance patterns have left insulation performing at R-6 or below in homes owners assumed were adequate. That specific wear pattern changes how we approach every Converse job.
Our Main Converse Services
Converse homeowners contact us most often for attic work and spray foam retrofits. These three services have dedicated Converse pages with deeper pricing and local case details:
Attic Insulation in Converse
Attic insulation in Converse means dealing with compressed 1960s batts, minimum-code blown fiberglass from the 2000s building boom, or attics where base-required HVAC inspections have trampled insulation flat. We start with a blower-door test to measure air leakage, then seal before insulating. Most Converse attic jobs pair new insulation with air sealing and often radiant barrier. Read more on our Attic Insulation in Converse page.

Spray Foam Insulation in Converse
Spray foam insulation in Converse works best for the 2000s-era subdivisions with complex rooflines and knee walls where batt insulation gaps are inevitable, or for homeowners converting unconditioned attic space. We use open-cell and closed-cell products from Demilec and Icynene, selected by application, not by brand exclusivity. Every job gets a written price before work starts. Details are on our Spray Foam Insulation in Converse page.

Blown-In Insulation in Converse
Blown-in insulation in Converse is the most common retrofit for 1950s-1970s ranch homes with settled batts. We blow Owens Corning or Johns Manville fiberglass, or GreenFiber cellulose, over sealed attic floors after blower-door-guided air sealing. The material choice depends on your roof deck condition and whether we’re pairing with radiant barrier. See full pricing and process on our Blown-In Insulation in Converse page.

Crawl Space Encapsulation & Vapor Barrier in Converse

Crawl space encapsulation and vapor barrier work in Converse addresses a specific regional problem: slab-on-grade construction dominates, but where crawl spaces do exist, they’re often in older additions or converted porches with no effective moisture control. The combination of high summer humidity, clay soils that hold water, and original 6-mil polyethylene that has degraded after 20+ years means we regularly find relative humidity above 80% in Converse crawl spaces. That moisture migrates upward through floor assemblies, degrading insulation and creating conditions for mold. We treat Crawl Space Encapsulation & Vapor Barrier as a building-envelope repair, not a maintenance add-on.
Crawl Space Vapor Barrier
Signs you need it
You smell mustiness from floor registers, see condensation on ductwork, or find the existing polyethylene sheeting brittle and torn.
What it costs in Converse
Most vapor barrier replacements in Converse run $1,200-$2,400 depending on crawl space square footage and whether we need to remove degraded material first.
How we do it
We remove old sheeting, grade the soil surface, lay 10-mil or thicker reinforced polyethylene with sealed seams, and extend it 6 inches up foundation walls.
Crawl Space Encapsulation
Signs you need it
Your crawl space has standing water after rains, mold on floor joists, or insulation falling from the subfloor due to moisture weight.
What it costs in Converse
Full encapsulation in Converse typically ranges from $3,500-$7,000 for conditioned perimeter walls with closed-cell foam and dehumidifier integration.
How we do it
We seal all vents, insulate walls with closed-cell spray foam, install a heavy-duty vapor barrier across the floor and up walls, and add a dedicated dehumidifier with condensate pump.
What Crawl Space Encapsulation & Vapor Barrier Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Vapor barrier replacement (6-mil to 10-mil) | $1,200 - $2,400 |
| Partial encapsulation (floor + wall base) | $2,800 - $4,500 |
| Full encapsulation with dehumidifier | $3,500 - $7,000 |
How long does crawl space encapsulation take in Converse?
Most Converse encapsulation jobs finish in one to two days. Larger crawl spaces or those requiring mold remediation first may extend to three days. We give you a written schedule with the written price before anyone starts.
Will encapsulation lower my cooling bills?
Yes, typically 10-20% in Converse homes where crawl space humidity was forcing the HVAC system to overcool for comfort. We document pre- and post-conditions with photos and humidity readings.
Radiant Barrier Installation in Converse

Radiant barrier installation in Converse is nearly essential given our climate zone. Summer attic temperatures above 150°F radiate downward through standard insulation, and the low-pitch ranch roofs common near JBSA-Randolph have minimal ventilation clearance, trapping heat. We’ve measured attic floor temperatures 30-40°F lower after radiant barrier installation in Converse homes, which directly reduces the cooling load that compressed 1960s batts or minimum-code blown fiberglass cannot handle. Radiant Barrier Installation is often the highest-ROI single upgrade for base-adjacent housing stock.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot after sunset, your AC runs continuously on summer afternoons, or your roof decking is too hot to touch from inside the attic.
What it costs in Converse
Attic radiant barrier installation in Converse typically runs $1,500-$3,200 for a standard 1,400-2,000 square foot ranch home.
How we do it
We staple perforated radiant barrier foil across attic truss bottoms or lay it over existing insulation, maintaining ventilation paths and avoiding compression of the thermal layer below.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the radiant barrier integrated at the deck level for maximum effectiveness and clean attic appearance.
What it costs in Converse
Roof-deck radiant barrier installed during re-roofing in Converse adds $1,200-$2,800 to the roofing project depending on deck square footage and pitch complexity.
How we do it
We install radiant barrier sheathing or foil-faced decking during roof replacement, taping all seams for continuity and coordinating with your roofing contractor’s schedule.
What Radiant Barrier Installation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic radiant barrier (foil over trusses) | $1,500 - $3,200 |
| Radiant barrier roof deck (with re-roof) | $1,200 - $2,800 |
| Radiant barrier + attic air sealing package | $2,400 - $4,500 |
Does radiant barrier work with my old insulation?
Yes, radiant barrier complements rather than replaces thermal insulation. In Converse homes with R-6 compressed batts, we typically air seal, add blown insulation to R-38, then install radiant barrier for the full assembly.
How much cooler will my attic get?
We typically measure 25-35°F reduction in attic air temperature and 30-50°F reduction in radiant heat transfer at the attic floor. You’ll get before-and-after infrared images showing the difference.
Insulation Removal & Replacement in Converse

Insulation removal and replacement in Converse is common for two reasons: decades of moisture degradation in original fiberglass batts, and rodent or insect contamination that makes existing insulation a health hazard rather than a thermal asset. The base-adjacent maintenance pattern of annual HVAC inspections has also compressed insulation in many attics to the point where removal is more efficient than topping off. We don’t blow new material over failed old material. Insulation Removal & Replacement means complete extraction, sanitization if needed, then a fresh assembly starting with air sealing.
Contaminated Insulation Removal
Signs you need it
You smell ammonia or musk in the attic, see rodent droppings, or find insulation stained with urine that has degraded the fibers and created airborne particulate risk.
What it costs in Converse
Contaminated insulation removal in Converse runs $2,000-$4,500 including HEPA vacuum extraction, bagging, and attic sanitization before new material goes in.
How we do it
We set up negative air pressure, remove contaminated material with HEPA-filtered equipment, apply enzymatic sanitizer to affected surfaces, and verify air quality before sealing and reinsulating.
Insulation Replacement
Signs you need it
Your insulation has compressed below its labeled R-value, shows water staining from past leaks, or has been disturbed by multiple service trades to the point of fragmentation.
What it costs in Converse
Full insulation replacement in a standard Converse ranch attic typically ranges from $2,500-$5,000 including removal, air sealing, and new blown fiberglass or cellulose to current IECC standards.
How we do it
We remove old material completely, photograph and document the bare attic condition, seal all top plates and penetrations, then install new insulation with even depth and full coverage verification.
What Insulation Removal & Replacement Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Contaminated insulation removal + sanitize | $2,000 - $4,500 |
| Standard removal + replacement (blown) | $2,500 - $5,000 |
| Removal + spray foam replacement | $4,000 - $8,500 |
Can you remove insulation with asbestos?
We do not handle asbestos-containing materials. If your Converse home was built before 1980, we’ll arrange third-party testing before disturbing any vermiculite or early fiberglass batts. If asbestos is present, we refer to licensed abatement contractors.
How long does removal and replacement take?
Most Converse jobs finish in two days: one for removal and sanitization, one for air sealing and new insulation. Large attics or heavy contamination may add a day. The written schedule is part of your written price.
Attic Air Sealing in Converse

Attic air sealing in Converse is the single most overlooked upgrade in base-adjacent housing stock. Decades of HVAC service, antenna installation, and minor electrical work have punched dozens of unsealed penetrations through top plates and drywall. The original builders never sealed them, and subsequent trades never closed them. We regularly measure 4,000+ CFM50 on blower-door tests in Converse homes that look “fine” from the attic hatch. Attic Air Sealing is always step one before adding insulation; under Haven Standard, we will not blow insulation over an unsealed attic floor.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from outlets on exterior walls, see dusty streaks around ceiling fixtures, or measure temperature differences of more than 5°F between rooms on the same HVAC zone.
What it costs in Converse
Top plate and penetration sealing in a standard Converse ranch runs $1,200-$2,800 as a standalone job, or it’s included in our attic insulation packages.
How we do it
We use blower-door guidance to locate leaks, then seal top plates with acoustic sealant and rigid foam, and fill wire and pipe penetrations with fire-rated caulk and expanding foam.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in windy weather, you see insulation dust on furniture below fixtures, or your duct boots show rust from condensation driven by attic air infiltration.
What it costs in Converse
Can light sealing with approved covers and duct boot sealing in Converse typically adds $800-$1,800 to an air sealing package depending on fixture count.
How we do it
We install fire-rated airtight covers over IC and non-IC can lights, seal duct boots to drywall with mastic and mesh, and verify with blower-door differential testing.
What Attic Air Sealing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Top plate & penetration sealing | $1,200 - $2,800 |
| Can light & duct boot sealing | $800 - $1,800 |
| Full attic air sealing (comprehensive) | $2,000 - $4,200 |
Will air sealing alone save money?
Yes, typically 15-25% on heating and cooling in Converse homes with significant leakage. We document the improvement with before-and-after blower-door numbers so you can verify the result yourself.
Do I need to leave during air sealing?
No. The work is contained to the attic, and we use low-VOC sealants. You may hear compressor noise for the blower-door test, which we run at start and finish to measure our progress.
Wall Insulation in Converse

Wall insulation in Converse presents a specific challenge: the 1950s-1970s ranch homes have empty 2×4 stud cavities with no insulation at all, while the 2000s-era homes have minimal kraft-faced batts that settled and left gaps. Neither era was built with continuous exterior insulation. In our hot-humid climate, that means exterior walls radiate heat inward all summer and lose conditioned air outward through convection loops inside the cavity. Wall Insulation retrofits require injection or drill-and-fill methods that don’t require interior demolition.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls are hot to the touch on summer afternoons, your AC cannot maintain setpoint during peak hours, or an infrared camera shows framing members as cold spots in winter.
What it costs in Converse
Injection foam wall insulation for a standard 1,500 square foot Converse ranch runs $3,500-$6,500 depending on wall height, cavity condition, and access.
How we do it
We drill 5/8-inch holes through exterior siding at stud-bay spacing, inject slow-rise foam that fills around obstructions, then plug and match siding texture.
Drill & Fill Wall Insulation
Signs you need it
You have some existing batt insulation in walls but it’s compressed, moisture-stained, or gapped around electrical boxes and plumbing stacks.
What it costs in Converse
Drill-and-fill with blown fiberglass or cellulose in Converse typically ranges $2,800-$5,000 for a complete exterior wall package.
How we do it
We remove minimal siding, drill at top and bottom of each bay, blow material to verified density, then seal penetrations and restore siding.
What Wall Insulation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Injection foam (exterior walls) | $3,500 - $6,500 |
| Drill & fill (blown fiberglass/cellulose) | $2,800 - $5,000 |
| Interior wall soundproofing | $1,800 - $3,500 |
Will injection foam damage my siding?
No. We drill through siding, not remove it, and match plugs to existing color and texture. On vinyl siding, we work from behind where possible. Photos of completed repairs are in your Documented Photo Record.
How much does wall insulation help in Converse?
Significantly. Uninsulated 2×4 walls in Converse perform at roughly R-4 with sheathing and air films. Filled cavities reach R-13 to R-15, cutting conductive heat gain by 60-70% through the wall assembly.
Attic Cleaning & Rodent Proofing in Converse

Attic cleaning and rodent proofing in Converse is a frequent need in base-adjacent neighborhoods where mature oak canopy, established utility easements, and slab-on-grade construction create ideal rodent highway conditions. Roof rats and mice access attics through gaps at fascia boards, vent screens, and plumbing penetrations, then compress and contaminate insulation while creating fire hazards by gnawing wiring. The 1960s-era homes with minimal original air sealing offer entry points every few feet along the roofline. Attic Cleaning & Rodent Proofing restores the attic to a clean, sealed condition.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find droppings in the attic, or see gnaw marks on soffit vents and fascia where rodents have enlarged entry points.
What it costs in Converse
Rodent proofing and exclusion for a standard Converse ranch typically runs $1,500-$3,200 including entry sealing, vent screening, and one-way door installation if active infestation exists.
How we do it
We inspect every roofline foot with a ladder and mirror, seal gaps with rodent-proof materials, install heavy-gauge vent screens, and place one-way doors on active runs to let occupants out without return.
Attic Sanitizing & Decontamination
Signs you need it
Your attic smells of ammonia, shows urine-stained insulation, or has visible rodent carcasses or nesting material that creates airborne pathogen risk during HVAC operation.
What it costs in Converse
Attic sanitizing and decontamination in Converse ranges $1,800-$3,500 depending on contamination extent, insulation removal needs, and square footage.
How we do it
We remove contaminated material under negative pressure, apply enzymatic sanitizer to all surfaces, HEPA-vacuum the entire attic, and verify with ATP testing before any new work begins.
What Attic Cleaning & Rodent Proofing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Rodent proofing & exclusion | $1,500 - $3,200 |
| Attic sanitizing & decontamination | $1,800 - $3,500 |
| Full attic restoration (cleanout + proofing + reinsulate) | $4,500 - $8,500 |
How do I know if rodents are in my attic?
Listen for scratching after dark, check for droppings near attic hatches, and look for gnawed vent screens or stained soffit areas. We include a full attic inspection with photo documentation in every estimate.
Will rodents come back after proofing?
Not through the same entry points. Our exclusion work carries the 365-Day Done Right Promise: if rodents re-enter through sealed areas, we return and repair at no charge. New damage from falling branches or subsequent trades is separate.
Home Energy Audit in Converse

A home energy audit in Converse gives you a documented baseline before spending on upgrades. Given the specific wear patterns in base-adjacent housing, many homeowners assume they need new insulation when the actual problem is air leakage, duct loss, or an HVAC system oversized for the actual load. Our audits measure all three. We use blower-door testing, thermal imaging, and duct blaster testing to separate real problems from assumed ones. Home Energy Audit results include prioritized recommendations with estimated savings and written prices for each measure.
Blower Door Test
Signs you need it
Your home feels drafty despite closed windows, your energy bills are 30% higher than neighbors with similar homes, or you’re planning insulation upgrades and want to verify air sealing needs first.
What it costs in Converse
A standalone blower-door test in Converse runs $350-$550, or it’s included at no additional charge when bundled with our full home energy audit package.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage and locate major leak paths with smoke pencils and infrared.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach comfortable temperature, suspect missing insulation in walls or ceilings, or want to verify contractor work quality on a recent insulation job.
What it costs in Converse
Thermal imaging inspection in Converse typically costs $250-$450 as a standalone service, or it’s combined with the blower-door test in our full audit.
How we do it
We scan every interior and exterior surface with a FLIR camera during controlled conditions, identifying insulation gaps, moisture intrusion, and thermal bridging that visual inspection cannot detect.
What Home Energy Audit Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Blower door test (standalone) | $350 - $550 |
| Thermal imaging inspection | $250 - $450 |
| Full home energy audit (comprehensive) | $450 - $750 |
What does a home energy audit include?
Our full audit includes blower-door test, thermal imaging, insulation inspection, duct leakage test, and a written report with prioritized recommendations and fixed prices for each measure. You keep all documentation.
Should I audit before or after buying a home in Converse?
Before, if possible. Many 1960s-1970s Converse homes show $3,000-$8,000 in needed envelope work that a standard inspection misses. The audit gives you negotiating documentation and a repair roadmap.
