Insulation in Converse, TX
Most crawl spaces in Converse were built with bare earth floors and minimal moisture protection, making Crawl Space Encapsulation & Vapor Barrier the starting point for any serious energy upgrade in this market. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before adding insulation anywhere in the building envelope. If your Converse home was built between 1993 and 2012, there’s a strong chance the original insulation has settled below its rated R-value and the attic floor was never sealed. Call (830) 402-5240 for a written price before any work starts.
Why Converse Homes Are Different
Converse expanded almost entirely during the 1990s and 2000s as a bedroom community for JBSA-Randolph Air Force Base, leaving the city with a dense, uniform stock of builder-grade tract homes insulated to the minimum standards of that era. Most walls carry R-19 to R-22 and attics were originally blown to R-30, both well below current Texas energy code targets of R-38 to R-49. The city’s unusually high military-family rental turnover means energy upgrades are routinely deferred by absentee landlords, so retroactive attic re-insulation and air-sealing dominate the local service market in a way that wouldn’t be as pronounced in owner-stable suburbs nearby.
Sitting in the northeast San Antonio metro, Converse endures summer attic temperatures that routinely exceed 140°F, making under-insulated attics the dominant driver of runaway cooling bills. The February 2021 Winter Storm Uri freeze also exposed insulation voids in pipe chases and exterior wall cavities across this era of construction, many of which remain unaddressed. Tract homes along the FM 78 and Kitty Hawk Road corridors were commonly built with non-airtight recessed can lights installed in ceilings directly below unconditioned attics, creating direct thermal chimneys that blower-door tests consistently flag as the single largest air-leakage point before any insulation work begins.
Our Main Converse Services
These are the two services Converse homeowners call about most, with blown-in rounding out the top three:
Attic Insulation in Converse
Converse attics were originally blown with fiberglass to R-30, but after twenty-plus years of 140°F summers, that material has settled and shifted, often leaving the center of the attic at R-20 or lower. We start every attic job with a blower-door test to measure air leakage, then seal top plates and can lights before adding any new material. Attic Insulation in Converse is where most of our local work begins.
Spray Foam Insulation in Converse
Spray foam makes sense in Converse for homeowners who want to condition their attic or seal complex rooflines where batt insulation leaves gaps. We use open-cell and closed-cell products from Owens Corning and Demilec, selected by application rather than brand loyalty. Spray Foam Insulation in Converse works best when the attic floor is already sealed or when the roof deck itself is the target.
Blown-In Insulation in Converse
Blown-in cellulose and fiberglass are the standard retrofit for Converse’s settled attics, but we never blow over an unsealed attic floor. The Haven Standard requires air sealing first, then insulation, in that order. Blown-In Insulation in Converse delivers the best return when the prep work is documented and the homeowner gets before-and-after blower-door numbers.

Crawl Space Encapsulation & Vapor Barrier in Converse
Most crawl spaces in Converse sit on bare earth with no vapor barrier, or a thin 6-mil sheet that has torn and shifted over decades. The clay soils in this part of Bexar County hold moisture year-round, and that moisture evaporates directly into the floor system, raising indoor humidity and creating conditions for mold and wood rot. Crawl Space Encapsulation & Vapor Barrier is the only way to break that cycle permanently.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare earth, standing water after rain, or a thin torn plastic sheet that no longer covers the full floor.
What it costs in Converse
A full crawl space vapor barrier installation in Converse typically runs $1,800 to $3,500 depending on square footage and whether drainage matting is needed.
How we do it
We remove debris, grade the earth, lay a 12-mil reinforced polyethylene barrier sealed at all seams and walls, and install mechanical fasteners at the perimeter.
Crawl Space Encapsulation
Signs you need it
Musty odors rise from the floor, hardwood cupping appears, or humidity readings in the crawl space stay above 70% year-round.
What it costs in Converse
Complete crawl space encapsulation in Converse generally ranges from $4,500 to $8,000 including vapor barrier, sealed vents, dehumidifier, and insulation on foundation walls.
How we do it
We seal all vents, install a reinforced liner on walls and floor, add closed-cell foam on rim joists, and size a dedicated dehumidifier to maintain 50-55% relative humidity.
What Crawl Space Encapsulation & Vapor Barrier Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Crawl space vapor barrier (12-mil, floor only) | $1,800 - $3,500 |
| Full crawl space encapsulation | $4,500 - $8,000 |
| Rim joist insulation (closed-cell foam, add-on) | $1,200 - $2,400 |
How long does crawl space encapsulation take in Converse?
Most Converse crawl space encapsulations are completed in two to three days. Vapor barrier-only jobs typically finish in one day. We provide a written schedule with the price before work begins.
Will encapsulation stop mold in my Converse crawl space?
Encapsulation eliminates the moisture source that fuels mold, but active mold must be remediated first. We document existing conditions with photos and coordinate remediation if needed before sealing.
Radiant Barrier Installation in Converse
Converse attics hit 140°F regularly from May through September, and radiant heat from the roof deck radiates downward into insulation and ductwork, reducing effective R-value and forcing AC systems to run longer. A radiant barrier reflects that heat back toward the roof rather than letting it penetrate the living space. Radiant Barrier Installation is most effective in Converse when paired with adequate attic insulation and ventilation.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot after sunset, ductwork in the attic feels hot to the touch, or cooling bills spike despite a recently serviced AC unit.
What it costs in Converse
Radiant barrier installation in a typical Converse attic runs $1,200 to $2,800 depending on roof complexity and whether we use foil or spray-applied coating.
How we do it
We staple perforated foil across bottom chords of roof trusses or spray a low-emissivity coating directly to the roof deck, maintaining a dust-facing air gap for performance.
Radiant Barrier & Ventilation
Signs you need it
Your attic has no ridge vent, soffit vents are blocked by insulation, or bathroom fans dump moist air directly into the attic space.
What it costs in Converse
Radiant barrier plus ventilation correction in Converse typically ranges from $2,000 to $4,500 including baffles, vent extension, and exhaust routing.
How we do it
We install baffles to preserve soffit airflow, add or extend ridge vents where structurally feasible, and route exhaust fans through the roof with insulated ducts.
What Radiant Barrier Installation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic radiant barrier (foil, stapled) | $1,200 - $2,800 |
| Spray-applied radiant barrier coating | $1,500 - $3,200 |
| Radiant barrier with ventilation correction | $2,000 - $4,500 |
Does radiant barrier work with existing insulation?
Yes, radiant barrier complements existing insulation by reducing the heat load that insulation must resist. We install it after air sealing but before adding new blown material.
How much can radiant barrier lower my Converse cooling bill?
Converse homeowners with radiant barriers typically see attic heat transfer reductions of 20-35% in summer months. Actual bill impact depends on duct location, insulation level, and AC efficiency.
Insulation Removal & Replacement in Converse
Converse homes built in the 1990s and 2000s are now reaching the age where original blown fiberglass has settled, compacted, and in many cases been compromised by roof leaks or rodent activity. The uniform construction era means we’re seeing waves of these homes needing full attic resets. Insulation Removal & Replacement in Converse almost always reveals unsealed top plates and non-IC can lights that should be addressed before new material goes in.
Contaminated Insulation Removal
Signs you need it
You smell urine when the attic hatch opens, see droppings, or find insulation stained with rodent waste or water marks from past leaks.
What it costs in Converse
Contaminated insulation removal in Converse runs $2.50 to $4.50 per square foot of attic floor, with most homes falling between $1,800 and $3,600.
How we do it
We use commercial vacuums with HEPA filtration, bag waste on site, apply EPA-registered sanitizer to exposed decking, and document the empty attic with photos before sealing.
Insulation Replacement
Signs you need it
Your attic insulation measures below R-30 with a yardstick, has visible gaps near eaves, or was disturbed by prior contractors who never restored coverage.
What it costs in Converse
Insulation replacement with new blown fiberglass or cellulose in Converse typically costs $1.50 to $3.00 per square foot installed, or $1,200 to $2,800 for a standard 1,800-square-foot attic.
How we do it
We air seal first, then blow Johns Manville or GreenFiber cellulose to the specified depth, install rulers for verification, and provide before-and-after blower-door readings.
What Insulation Removal & Replacement Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Contaminated insulation removal | $1,800 - $3,600 |
| Insulation replacement (blown, standard attic) | $1,200 - $2,800 |
| Removal plus replacement package | $3,200 - $6,200 |
Is it cheaper to remove old insulation or add over it?
Adding over contaminated or water-damaged insulation is never recommended. In Converse, removal plus replacement costs more upfront but prevents mold, odor, and efficiency losses that layered-over problems create.
How do I know if my Converse attic insulation is contaminated?
Dark staining, compressed paths, ammonia odors, or visible droppings indicate contamination. We inspect and photograph before quoting removal. Call (830) 402-5240 for a documented assessment.
Attic Air Sealing in Converse
The tract homes along FM 78 and Kitty Hawk Road in Converse were built with non-airtight recessed can lights that create direct thermal chimneys between conditioned space and 140°F attics. Before any insulation is added, these leaks must be sealed or the new material will simply hide the problem. Attic Air Sealing is the foundation of every job we do in Converse under The Haven Standard.
Can Light & Duct Boot Sealing
Signs you need it
Dust streaks around ceiling cans, hot spots on infrared camera, or rooms that never reach set temperature despite adequate insulation depth.
What it costs in Converse
Sealing can lights and duct boots in a typical Converse attic runs $800 to $1,800 depending on quantity and accessibility.
How we do it
We cover non-IC cans with fire-rated enclosures, seal with high-temperature caulk, and mastic-seal duct boots to drywall before any insulation touches the attic floor.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage despite closed windows, or you feel drafts at baseboards and electrical outlets on exterior walls.
What it costs in Converse
Top plate and penetration sealing in Converse typically ranges from $1,200 to $2,500 for a complete attic floor seal on a 1,800-square-foot home.
How we do it
We foam-seal all top plates, wire penetrations, plumbing stacks, and chimney chases, then retest with the blower door to verify leakage reduction.
What Attic Air Sealing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Can light and duct boot sealing | $800 - $1,800 |
| Top plate and penetration sealing | $1,200 - $2,500 |
| Full attic air sealing (comprehensive) | $2,000 - $4,000 |
Can air sealing alone lower my Converse energy bills?
Yes, many Converse homes see 15-25% heating and cooling reduction from air sealing alone. We provide before-and-after blower-door numbers so you can verify the change.
Do you seal attic air leaks before adding insulation?
Always. The Haven Standard requires sealing before insulating. We have never and will never blow insulation over an unsealed attic floor.
Wall Insulation in Converse
Converse walls built in the 1990s and 2000s were insulated to R-19 or R-22 with fiberglass batts that have settled, compressed, or left gaps at studs and electrical boxes. The February 2021 freeze exposed how many of these walls had voids in pipe chases that allowed freeze damage. Wall Insulation retrofits in Converse focus on filling those voids without tearing out drywall.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel cold to the touch in winter, rooms have uneven temperatures, or your 1990s-era home was built with minimal cavity insulation.
What it costs in Converse
Injection foam wall insulation in Converse runs $3.00 to $5.50 per square foot of wall area, with most homes ranging from $2,500 to $5,000.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam that fills around existing wiring and plumbing, then plug and texture-match the holes.
Drill & Fill Wall Insulation
Signs you need it
Your walls have no insulation or failed cellulose that has settled to the bottom of the cavity, leaving the upper half empty.
What it costs in Converse
Drill and fill with dense-pack cellulose in Converse typically costs $2.00 to $4.00 per square foot, or $1,800 to $3,600 for a standard home.
How we do it
We remove existing siding or drill through interior drywall, blow GreenFiber cellulose to 3.5 pounds per cubic foot density, and seal penetrations with matched materials.
What Wall Insulation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Injection foam wall insulation | $2,500 - $5,000 |
| Drill and fill (dense-pack cellulose) | $1,800 - $3,600 |
| Exterior wall insulation (full removal and replace) | $4,000 - $7,500 |
Can you insulate walls without removing drywall?
Yes, injection foam and dense-pack cellulose both fill existing cavities through small drilled holes. We patch and texture-match so the repair is invisible.
Will wall insulation help with the next freeze in Converse?
Properly filled wall cavities reduce cold transfer to pipes and improve comfort. We specifically target pipe chases and exterior wall plumbing locations noted during the assessment.
Attic Cleaning & Rodent Proofing in Converse
The mature trees and established neighborhoods in Converse create sustained rodent pressure on attics, particularly in homes near greenbelts or with overhead utility lines. Military rental turnover means some attits go years between thorough inspections, allowing colonies to establish and contaminate insulation. Attic Cleaning & Rodent Proofing in Converse always includes proofing, because cleaning without exclusion guarantees repeat problems.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia or musk from the attic, see droppings on insulation, or find nesting material in soffits and corners.
What it costs in Converse
Attic sanitizing and decontamination in Converse runs $1,500 to $3,200 depending on contamination extent and attic square footage.
How we do it
We remove soiled insulation, HEPA-vacuum all surfaces, apply enzyme-based sanitizer, and run an ozone treatment before any new material is installed.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find chew marks on fascia boards, or see gaps larger than a quarter inch at roof junctions and pipe penetrations.
What it costs in Converse
Rodent proofing and exclusion for a typical Converse home ranges from $800 to $2,000 including sealing, hardware cloth, and one-way exit devices.
How we do it
We seal all entry points with rodent-proof materials, install one-way exits over active holes, and provide a written warranty on exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic sanitizing and decontamination | $1,500 - $3,200 |
| Rodent proofing and exclusion | $800 - $2,000 |
| Full attic restoration (cleaning, proofing, re-insulation) | $3,500 - $7,000 |
How do I know rodents are gone before you re-insulate?
We install one-way exits and monitor for activity for 7-10 days before sealing final entry points and installing new insulation. No new material goes in until exclusion is verified.
Does rodent proofing include the crawl space?
Crawl space entry points are included in our standard exclusion scope. We inspect the full building envelope because rodents rarely use only one access route.
Home Energy Audit in Converse
Converse’s uniform housing stock means energy problems follow predictable patterns, but every home has unique leakage paths and insulation voids that only testing reveals. A proper audit identifies whether your money is better spent on air sealing, insulation, or both. Home Energy Audit is where every Converse project should start, and where we establish the baseline numbers that prove results later.
Blower Door Test
Signs you need it
Your energy bills are rising without rate increases, rooms have uneven temperatures, or you want documented proof before investing in upgrades.
What it costs in Converse
A standalone blower-door test in Converse costs $350 to $600; when bundled with thermal imaging and full audit report, the package runs $500 to $900.
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 in one number.
Thermal Imaging Inspection
Signs you need it
You suspect insulation voids, have rooms that never hold temperature, or want visual proof of air leakage before committing to repairs.
What it costs in Converse
Thermal imaging included in a full audit runs $500 to $900 total; standalone thermal scans start at $400 for a typical Converse home.
How we do it
We run the blower door while capturing infrared images to make air leakage visible, then mark problem areas on photos you keep with the written report.
What Home Energy Audit Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Blower-door test (standalone) | $350 - $600 |
| Full home energy audit with thermal imaging | $500 - $900 |
| Duct leakage test (add-on) | $250 - $450 |
What does a home energy audit include in Converse?
Our Converse audits include blower-door test, thermal imaging, insulation depth check, duct inspection, and a written report with prioritized recommendations and price ranges.
Can I use audit results for CPS Energy rebates?
Yes, our audit documentation meets CPS Energy program requirements. We provide the specific test results and contractor certification needed for rebate applications.
