Insulation in Converse, TX
Crawl space encapsulation and vapor barrier work in Converse typically runs $2,800-$5,500 for a full encapsulation, with vapor barriers alone starting around $1,200-$2,400 depending on crawl space square footage and existing moisture damage. Most Converse homes sit on slab foundations, but the remaining crawl spaces - often in additions or older sections near FM 78 - trap the San Antonio basin’s humid air against floor joists year-round. If you’re seeing musty indoor air or soft spots above a crawl space, call (737) 227-6219 and we’ll send a crew with a written price before any work starts.
Why Converse Homes Are Different
Converse grew rapidly in the 1980s and 1990s as an affordable bedroom community for families connected to Randolph Air Force Base, now Joint Base San Antonio-Randolph. That growth left an unusually dense concentration of slab-on-grade tract homes built to minimal energy codes of that era - typically R-19 or less in the attic and thin fiberglass batts in 2×4 walls. High military-family tenant turnover meant landlords deferred insulation upgrades for years, making attic retrofit and upgrade work the dominant insulation job type here in a way that differs from older, more diverse neighboring suburbs.
The San Antonio basin climate pushes Converse attics past 150°F on routine summer afternoons, making cooling-load reduction the primary economic driver for insulation upgrades. The February 2021 winter storm exposed how poorly that thin-wall construction performed during hard freezes. Because rentals cycle through military families on short PCS assignments, tenants rarely escalate high utility bills to landlords, so original 1980s blown-in fiberglass can settle to R-15 or below for 20-plus years undetected. Technicians most often discover this during pre-sale inspections when ownership finally changes hands.
Our Main Converse Services
Converse homeowners call us most often for attic work and spray foam retrofits, but blown-in remains the most common upgrade path for the area’s vented attic stock.
Attic Insulation in Converse
Attic insulation in Converse almost always means upgrading R-19 or settled blown-in to modern R-38 or R-49 levels in vented hip or gable roofs. We begin with a blower-door test - a pressurization reading that shows, in one number, how much air the building envelope is losing - then seal top plates and can lights before adding any new material. Every job closes with a documented photo record and, on applicable work, before-and-after blower-door numbers. Attic Insulation in Converse covers our full process for these retrofits.
Spray Foam Insulation in Converse
Spray foam insulation in Converse works best for open attics, bonus rooms over garages, and the occasional crawl space where traditional batts fail against humidity. We use open-cell and closed-cell foams from Owens Corning and Demilec, selected by application, never pushed as a default. Because spray foam is a permanent modification, we provide a written scope, written warranty, and documented photo record before anyone lifts a tool. Spray Foam Insulation in Converse details when foam makes sense versus blown-in.
Blown-In Insulation in Converse
Blown-in insulation in Converse is the standard retrofit for the area’s thousands of vented attics with settled 1980s fiberglass. We install fiberglass from Johns Manville or Knauf, or cellulose from GreenFiber, depending on the attic’s moisture history and the homeowner’s preference. The material is secondary; what matters is that we seal first, then insulate - blowing new material over an unsealed attic floor is something we won’t do. Blown-In Insulation in Converse explains our sequencing.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Converse
Most Converse homes sit on slab foundations, but the remaining crawl spaces - often in additions near FM 78 or in pockets of older construction - trap the San Antonio basin’s humid air against floor joists year-round. Full Crawl Space Encapsulation & Vapor Barrier work addresses what slab homes never face: wood rot, mold spores, and the musty indoor air that rises through floor penetrations. We treat crawl spaces as building envelope failures that happen to be below grade, which means we measure, seal, and document them with the same rigor as attic work.
Crawl Space Vapor Barrier
Signs you need it
Condensation on ductwork, musty odors that worsen after rain, or soft spots in subflooring above the crawl space indicate vapor migration through bare earth.
What it costs in Converse
A 6-mil to 20-mil vapor barrier installation in Converse typically runs $1,200-$2,400 for standard crawl spaces under 1,200 square feet.
How we do it
We remove debris, grade the earth, seam-seal polyethylene sheeting at all overlaps, and mechanically fasten to walls and piers before documenting with photos.
Crawl Space Encapsulation
Signs you need it
Standing water after storms, visible mold on joists, or insulation falling from the floor cavity means the crawl space is actively exchanging moisture with the living space above.
What it costs in Converse
Full encapsulation with sealed vapor barrier, wall insulation, and conditioned air supply in Converse generally ranges $2,800-$5,500 depending on access and existing damage.
How we do it
We install a sealed ground barrier, insulate perimeter walls with rigid foam, seal all vents and penetrations, and add mechanical dehumidification where needed.
What Crawl Space Encapsulation & Vapor Barrier Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Vapor barrier (6-20 mil, ground only) | $1,200 - $2,400 |
| Full encapsulation with dehumidifier | $2,800 - $5,500 |
| Crawl space insulation (rigid foam walls) | $1,800 - $3,200 |
How long does crawl space encapsulation take in Converse?
Most vapor barrier jobs finish in one day; full encapsulations with dehumidification typically take two to three days depending on access and repairs needed. We provide a written schedule with the written price before work starts.
Will encapsulation stop musty smells in my Converse home?
Yes, when the source is crawl space moisture - sealing the ground and perimeter stops the vapor drive that carries odors and mold spores into living spaces. Call (737) 227-6219 for a free inspection and written price.
Radiant Barrier Installation in Converse
Converse attics regularly exceed 150°F in summer, and the 1980s-1990s housing stock was built with dark shingles over vented attics that function as solar ovens. Radiant barrier installation reflects infrared heat away from the attic floor and ductwork, reducing cooling load without adding insulation depth where truss spacing is already tight. We install radiant barrier as part of a complete envelope approach, not a standalone miracle fix.
Attic Radiant Barrier
Signs you need it
AC running continuously after 2 p.m., ducts sweating in the attic, or rooms that stay hot despite adequate insulation depth suggest radiant heat gain through the roof deck.
What it costs in Converse
Attic radiant barrier installation in Converse typically runs $1,100-$2,200 for a 1,500-2,500 square foot home with standard truss access.
How we do it
We staple perforated foil across truss bottoms or lay it over existing insulation, maintaining ventilation paths and documenting placement with photos.
Radiant Barrier Roof Deck
Signs you need it
New roof installation or re-roofing presents the only practical opportunity to apply radiant barrier directly to the roof deck before new decking goes down.
What it costs in Converse
Roof-deck radiant barrier applied during roofing in Converse adds $800-$1,500 to the roofing scope depending on pitch and square footage.
How we do it
We apply foil-faced sheathing or peel-and-stick membrane to the roof deck during tear-off, sealing seams and integrating with ridge venting.
What Radiant Barrier Installation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic radiant barrier (foil, truss application) | $1,100 - $2,200 |
| Radiant barrier roof deck (with re-roof) | $800 - $1,500 |
| Radiant barrier with attic air sealing package | $1,800 - $3,400 |
Does radiant barrier work with my existing insulation?
Yes - radiant barrier complements rather than replaces insulation; it blocks radiant heat transfer while fiberglass or foam slows conductive heat flow. We assess your current R-value before recommending placement.
How much will radiant barrier lower my cooling bill in Converse?
Most Converse homeowners see 5-10% cooling reduction, with larger gains in homes with dark shingles and ductwork in the attic. Call (737) 227-6219 for a free estimate with written price.
Insulation Removal & Replacement in Converse
Converse’s military-rental history means attics often contain 20-plus years of settled, compressed, or contaminated insulation that was never upgraded between tenants. Insulation removal and replacement addresses what new material alone cannot: rodent waste, water-stained batts, and the vermiculite occasionally found in pre-1990s additions. We document the condition we find, remove it completely, and start the envelope fresh.
Attic Insulation Removal
Signs you need it
Insulation compressed below joist tops, visible water staining, or a history of roof leaks means the existing material is performing well below its rated R-value.
What it costs in Converse
Attic insulation removal in Converse typically runs $1,000-$2,000 for a standard 1,500 square foot home with bagged disposal and HEPA containment.
How we do it
We set up negative air containment, remove material with industrial vacuums into sealed bags, and provide a documented photo record of the clean deck before any new work begins.
Contaminated Insulation Removal
Signs you need it
Strong urine odor in the attic, visible rodent tunnels, or insect debris indicates biological contamination that standard insulation covers rather than fixes.
What it costs in Converse
Contaminated insulation removal with sanitizing in Converse generally ranges $1,500-$3,000 depending on contamination extent and required PPE protocols.
How we do it
We remove all affected material, apply enzyme-based sanitizing agents to the deck and joists, and provide photographic documentation of the cleaned structure before reinsulating.
What Insulation Removal & Replacement Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Standard attic insulation removal | $1,000 - $2,000 |
| Contaminated insulation removal + sanitizing | $1,500 - $3,000 |
| Removal + replacement with new R-38 blown-in | $2,800 - $4,500 |
Can you remove insulation with asbestos or vermiculite?
We do not handle asbestos abatement; if we suspect vermiculite or asbestos-containing material, we stop work and refer you to a licensed abatement contractor for testing and removal. We resume with documented photo record once clearance is provided.
How do I know if my Converse attic needs removal or just more insulation?
We inspect for compression, moisture damage, and contamination during our free estimate; if the existing material is clean and dry, we seal and supplement rather than remove. Call (737) 227-6219 for a written assessment.
Attic Air Sealing in Converse
Converse’s 1980s-1990s tract homes were built with minimal attention to the pressure boundary; top plates, can lights, and duct boots were left as direct paths between conditioned space and vented attic. Attic air sealing is the prerequisite step we complete before any insulation goes in - blowing new material over an unsealed attic floor is something we refuse to do. The blower-door test proves the result: a single number showing how much conditioned air the home was losing before and after our work.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling outlets, cold drafts in winter despite closed windows, or rooms that never reach thermostat setpoint indicate attic air bypasses.
What it costs in Converse
Top plate and penetration sealing in Converse typically runs $800-$1,500 for a 1,500-2,000 square foot home with standard framing.
How we do it
We seal all top plate joints, wire and pipe penetrations, and chase openings with fire-rated caulk and foam, then verify with blower-door test.
Can Light & Duct Boot Sealing
Signs you need it
Condensation on can light trim in summer, dust collecting around ceiling registers, or whistling sounds from supply vents point to leaks at the thermal envelope.
What it costs in Converse
Can light and duct boot sealing in Converse generally ranges $400-$900 depending on fixture count and duct configuration.
How we do it
We install fire-rated covers over can lights, seal duct boots with mastic, 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 - $1,500 |
| Can light & duct boot sealing | $400 - $900 |
| Full attic air sealing (comprehensive) | $1,200 - $2,400 |
Do I need air sealing if I’m already adding insulation?
Yes - insulation slows heat transfer but does not stop air movement; unsealed leaks bypass even deep insulation and create moisture problems at the attic floor. We seal first, then insulate, in that order, always.
What blower-door number should a Converse home hit after sealing?
We target significant reduction from the pre-work baseline, with specific goals set by home size and construction era; you receive before-and-after readings in writing. Call (737) 227-6219 for a free assessment and written price.
Wall Insulation in Converse
Converse’s 2×4 exterior walls were built with R-11 or R-13 fiberglass batts that perform poorly in both summer heat gain and winter heat loss, as the February 2021 storm demonstrated across the region. Wall insulation retrofits in this market nearly always mean dense-pack or injection methods, since removing interior drywall is rarely cost-effective. We select the approach based on wall construction, siding type, and whether the home has brick veneer or hardboard siding.
Injection Foam Wall Insulation
Signs you need it
Hot or cold exterior walls to the touch, high utility bills despite adequate attic insulation, or rooms with exterior walls that lag behind interior temperature indicate underinsulated wall cavities.
What it costs in Converse
Injection foam wall insulation in Converse typically runs $2,500-$4,500 for a 1,500 square foot home with accessible stud cavities.
How we do it
We drill 5/8-inch holes at stud spacing, inject slow-rise foam to fill the cavity without bowing drywall, then plug and match texture where accessible.
Drill & Fill Wall Insulation
Signs you need it
Empty or settled wall cavities found during window replacement, or walls that sound hollow when tapped, suggest missing or degraded original insulation.
What it costs in Converse
Drill and fill with cellulose or fiberglass in Converse generally ranges $1,800-$3,200 depending on wall area and exterior finish type.
How we do it
We drill at the top of each cavity, blow cellulose or fiberglass to density, and seal penetrations with color-matched plugs for painted siding.
What Wall Insulation Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Injection foam (full exterior walls) | $2,500 - $4,500 |
| Drill & fill cellulose or fiberglass | $1,800 - $3,200 |
| Interior wall soundproofing (select rooms) | $900 - $1,800 |
Will injection foam damage my walls or siding?
We use slow-rise formulations and controlled pressure to avoid bowing; with brick veneer, we drill through mortar joints and repoint. We document pre-existing conditions with photos before starting.
Can you insulate walls without removing drywall?
Yes - injection and dense-pack methods fill existing cavities through small exterior or interior penetrations that we patch and match. Call (737) 227-6219 for a free assessment and written price.
Attic Cleaning & Rodent Proofing in Converse
Converse’s mature neighborhoods and tree canopy create sustained rodent pressure on attic spaces, while decades of tenant turnover in rental stock often meant minor infestations were never fully addressed. Attic cleaning and rodent proofing restores the attic to a clean, sealed condition before any new insulation goes in - we will not install material over contaminated substrate. The work ends with documented photos and a written scope of the exclusion work completed.
Attic Cleanout
Signs you need it
Visible droppings, nesting material in insulation, or stored items chewed through indicate active or recent rodent occupation requiring complete removal.
What it costs in Converse
Attic cleanout with debris removal and HEPA vacuuming in Converse typically runs $600-$1,200 for standard attic footprints.
How we do it
We remove all contaminated insulation and debris, HEPA-vacuum the deck and joists, and provide a documented photo record of the cleaned space.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds at night, new droppings after previous cleanup, or daylight visible through roof junctions mean entry points remain open and active.
What it costs in Converse
Rodent proofing and exclusion in Converse generally ranges $800-$1,800 depending on roof complexity and number of entry points identified.
How we do it
We seal all entry points 1/4-inch and larger with rodent-resistant materials, install vent screens, and provide a written map of exclusions completed.
What Attic Cleaning & Rodent Proofing Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Attic cleanout (debris & droppings removal) | $600 - $1,200 |
| Rodent proofing & exclusion | $800 - $1,800 |
| Full attic restoration (cleanout + proofing + sanitizing) | $1,800 - $3,500 |
Do you handle the rodents themselves or just seal the attic?
We focus on exclusion and habitat modification; if active infestation is present, we refer to a licensed pest control operator for trapping before we begin cleanup and sealing. We coordinate timing so the work flows without delay.
How do I know rodents won’t get back in after you seal?
We warranty our exclusion work for one year under the 365-Day Done Right Promise, and we document every sealed entry with photos; if they find a new path, we return and close it. Call (737) 227-6219 for a free inspection.
Home Energy Audit in Converse
A home energy audit in Converse identifies which of the common 1980s-1990s construction shortcuts are costing you money - whether it’s attic bypasses, duct leakage, or the thin wall insulation that failed so visibly in February 2021. We treat the audit as diagnostic work, not a sales pitch; you receive a written report with prioritized findings and flat-price options for each recommendation. Every audit includes blower-door testing and thermal imaging where temperature differentials allow.
Blower Door Test
Signs you need it
High utility bills with no obvious cause, rooms that won’t maintain temperature, or plans for insulation upgrades without knowing current air leakage all warrant a blower-door test.
What it costs in Converse
A standalone blower-door test in Converse typically runs $250-$400; when bundled with a full audit, the test is included in the comprehensive price.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure.
Thermal Imaging Inspection
Signs you need it
Hot or cold spots on walls and ceilings, moisture stains of unknown origin, or verification needed after insulation installation all show clearly in thermal imaging.
What it costs in Converse
Thermal imaging with written report in Converse generally ranges $200-$350 as a standalone service, or included in full audit packages.
How we do it
We scan the building envelope with a FLIR camera during blower-door depressurization to make air leaks visible, then annotate images in the written report.
What Home Energy Audit Costs in Converse
| Item | Typical range in Converse |
|---|---|
| Blower-door test (standalone) | $250 - $400 |
| Thermal imaging inspection | $200 - $350 |
| Full home energy audit (comprehensive) | $400 - $700 |
What does a home energy audit include in Converse?
A full audit includes blower-door test, thermal imaging, insulation and duct inspection, and a written report with prioritized findings and flat-price repair options. We schedule audits through our San Antonio office with crews serving Converse locally.
Will the audit tell me if I need new insulation or just air sealing?
Yes - the report separates air leakage from insulation deficiencies and gives you independent prices for each, so you can phase work by priority and budget. Call (737) 227-6219 to schedule; estimates are free.

What Converse Customers Say
"They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N."Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E."Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
- Ainsley P.
