Insulation in Schertz, TX
Crawl space encapsulation and vapor barrier work in Schertz typically runs $3,200-$6,800 for a full encapsulation, with most jobs scheduled within 48 hours. We’re Envelope Insulation Co., and we treat air sealing as a prerequisite, not an upsell - every crawl space job begins with sealing the rim joists and penetrations before any barrier goes down. If your Schertz home was built in the 2000s-era building boom, there’s a good chance the original crawl space work was code-minimum or missing entirely. Call (830) 549-6646 for a written price before any work starts.
Why Schertz Homes Are Different
Schertz sits at the southern edge of the Balcones Escarpment, where summer attic temperatures in dark-roofed tract homes routinely hit 150-160°F and hard freezes like February 2021 catch homeowners who assumed South Texas meant pipes were safe. The dominant housing stock - 1990s through 2010s production builds in Woodland Oaks, The Crossvine, and Schertz Parkway-area developments - was built to minimum IRC/IECC standards with 2×4 walls carrying R-13 batts and attics insulated just enough to pass inspection. That blown cellulose or fiberglass has settled from original R-30 to effective R-18 or lower after 15-25 years of thermal cycling. Near Randolph Air Force Base, high military-renter turnover means many of these homes have cycled through multiple tenants with zero insulation upgrades. The combination of extreme heat, occasional freeze risk, and deferred maintenance creates a specific envelope failure pattern we see repeatedly in Schertz.
Our Main Schertz Services
Most Schertz homeowners who call us start with attic work or spray foam. Here is how we handle the two most common requests, plus blown-in for settled attics.
Attic Insulation in Schertz
Attic insulation in Schertz almost always means dealing with settled blown-in from the 2000s building boom - we measure depth at the hatch and find original R-30 compressed to R-18 or less. Before adding anything, we seal top plates, can lights, and duct boots so the new insulation doesn’t just filter conditioned air into the attic. Every job gets a written price, documented photos, and blower-door numbers where applicable. Attic Insulation in Schertz

Spray Foam Insulation in Schertz
Spray foam makes sense in Schertz for bonus rooms over garages, cathedral ceilings, and rim joists in crawl spaces where batts have failed. We use open-cell and closed-cell products from Owens Corning and Demilec, selected by application, not by what’s cheapest to stock. Every spray foam job gets a written scope specifying thickness, density, and coverage area before the rig arrives. Spray Foam Insulation in Schertz

Blown-In Insulation in Schertz
Blown-in insulation in Schertz is typically a top-off over settled existing material or a full replacement after removal. We use fiberglass and cellulose from Johns Manville and GreenFiber, installed to depth after air sealing is complete. The crew documents starting depth, ending depth, and coverage area in the photo record you receive at job close. Blown-In Insulation in Schertz

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Schertz

Schertz’s 1990s-2010s slab-on-grade tract homes often have minimal crawl space attention during original construction, and the clay soils around the Balcones Escarpment hold moisture that migrates upward through vented crawl spaces. We provide Crawl Space Encapsulation & Vapor Barrier as a full envelope service, beginning with sealing the rim joists and penetrations before any membrane goes down - insulation over an unsealed floor just hides the problem.
Crawl Space Vapor Barrier
Signs you need it
Musty odors in first-floor rooms, sagging fiberglass batts between joists, or visible condensation on ductwork in the crawl space during humid months.
What it costs in Schertz
A 6-mil to 20-mil vapor barrier installation in Schertz typically runs $1,800-$3,400 depending on crawl space square footage and pier configuration.
How we do it
We remove debris and old fallen insulation, lay overlapping polyethylene sheeting sealed at seams and piers, and terminate edges to foundation walls before sealing the rim band.
Crawl Space Encapsulation
Signs you need it
Standing water after rains, mold on floor joists, hardwood cupping on the first floor, or HVAC ducts sweating in summer.
What it costs in Schertz
Full encapsulation with sealed vapor barrier, dehumidifier, and conditioned air supply in Schertz typically ranges $4,200-$7,800 for homes under 2,500 square feet.
How we do it
We seal all vents, install reinforced liner on walls and floor, seal rim joists with closed-cell foam, add a dedicated dehumidifier, and bring in a small conditioned air supply to maintain positive pressure.
What Crawl Space Encapsulation & Vapor Barrier Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Vapor barrier only (ground cover) | $1,800 - $3,400 |
| Partial encapsulation (floor + select walls) | $3,200 - $5,400 |
| Full encapsulation with dehumidifier | $4,200 - $7,800 |
Does crawl space encapsulation help with summer humidity in Schertz?
Yes - sealed crawl spaces block the 70-80% relative humidity common in Schertz summers from entering your floor system, which is why we see reduced HVAC runtime and eliminated floor condensation after encapsulation. Call (830) 549-6646 for a written price on your specific crawl space.
How long does crawl space encapsulation take in Schertz?
Most Schertz crawl spaces are completed in two to three days, with day one for prep and sealing, day two for liner installation and dehumidifier setup, and day three for final testing and documentation. We do not start without a written price and scope.
Radiant Barrier Installation in Schertz

Schertz’s 150-160°F attic temperatures in dark-roofed tract homes put extraordinary radiant load on ductwork and ceiling drywall, and production builders in the 2000s rarely installed radiant barriers despite the climate. We install Radiant Barrier Installation as a standalone retrofit or paired with insulation upgrades, always measuring attic temperature before and after to document the change.
Attic Radiant Barrier
Signs you need it
Second rooms that stay hot despite adequate insulation depth, ductwork too hot to touch in summer, or cooling bills that spike disproportionately to outdoor temperature.
What it costs in Schertz
Attic radiant barrier installation in Schertz typically runs $1,400-$2,800 for a standard 2,000-square-foot home, varying with roof pitch and accessibility.
How we do it
We staple perforated foil across bottom chords of roof trusses, maintaining ventilation channels, and measure attic temperature at multiple points before and after installation.
Radiant Barrier Roof Deck
Signs you need it
New roof installation planned, or existing roof deck accessible during a re-roof, with desire for the most effective radiant barrier placement possible.
What it costs in Schertz
Roof-deck radiant barrier application in Schertz, typically done during re-roofing, runs $2,200-$4,000 including material and labor for average home size.
How we do it
We apply foil-faced sheathing or spray-applied low-emissivity coating directly to the roof deck underside, sealing seams and integrating with ridge vent airflow patterns.
What Radiant Barrier Installation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic truss-mounted radiant barrier | $1,400 - $2,800 |
| Roof deck radiant barrier (during re-roof) | $2,200 - $4,000 |
| Radiant barrier with attic air sealing package | $2,800 - $5,200 |
Does radiant barrier work with existing insulation in Schertz?
Yes - radiant barrier complements rather than replaces insulation, reflecting radiant heat that passes through the roof deck while your existing fiberglass or cellulose handles conductive heat flow. We measure the combined effect with attic temperature readings. Call (830) 549-6646 for a written price.
How much cooler will my attic be with radiant barrier in Schertz?
Most Schertz attics see a 20-35°F drop in peak afternoon temperature after radiant barrier installation, with the greatest benefit in dark-shingled roofs with minimal existing shade.
Insulation Removal & Replacement in Schertz

Schertz’s 2000s-era production homes often contain insulation that has settled, been disturbed by rodents, or absorbed moisture through undetected roof leaks during tenant turnovers near Randolph AFB. We provide Insulation Removal & Replacement with full containment, HEPA filtration, and documented photo records of the cavity condition before new material goes in.
Contaminated Insulation Removal
Signs you need it
Visible rodent droppings, urine staining, mold growth, or musty odors that persist after duct cleaning and point to biological contamination in the insulation layer.
What it costs in Schertz
Contaminated insulation removal in Schertz typically runs $2,400-$4,600 depending on attic square footage, contamination extent, and required PPE level for the crew.
How we do it
We establish negative air pressure with HEPA-scrubbed exhaust, bag removed material in the attic, and provide photo documentation of the cleaned deck before any new insulation is quoted.
Insulation Replacement
Signs you need it
Insulation compressed below labeled R-value, water-stained batts, or uneven coverage with bare spots visible from the attic hatch.
What it costs in Schertz
Insulation replacement with new blown-in fiberglass or cellulose in Schertz typically ranges $2,800-$5,400 for attics between 1,500 and 2,500 square feet.
How we do it
We air seal all penetrations first, install baffles at eaves for ventilation, then blow to specified depth with depth markers placed every 300 square feet for verification.
What Insulation Removal & Replacement Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Contaminated insulation removal only | $2,400 - $4,600 |
| Standard insulation removal + disposal | $1,600 - $3,200 |
| Removal + replacement with air sealing | $3,800 - $7,200 |
Do I have to leave my house during insulation removal in Schertz?
No - our containment and negative-air setup keeps living spaces isolated, though we recommend sensitive individuals avoid the work zone during active removal. We provide a written scope and schedule before starting. Call (830) 549-6646 to arrange timing.
How do I know if my Schertz attic insulation is contaminated?
We inspect for droppings, staining, and odor during our initial assessment and photograph findings for your record; if contamination is present, we quote removal separately from replacement so you see exactly what each phase costs.
Attic Air Sealing in Schertz

Schertz’s production-built homes from the 2000s were framed quickly with minimal attention to envelope tightness, and the resulting air leakage - through top plates, can lights, and duct boots - destroys the performance of even properly installed insulation. We provide Attic Air Sealing as a standalone service or mandatory prerequisite to any insulation work, with before-and-after blower-door numbers on every job.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling fixtures, noticeable temperature variation between rooms, or high utility bills despite adequate insulation depth measured at the hatch.
What it costs in Schertz
Top plate and penetration sealing in Schertz typically runs $1,200-$2,400 for a standard production home, depending on framing complexity and number of interior walls.
How we do it
We seal all top plate gaps with fire-rated caulk or foam, address wire and pipe penetrations, and verify with blower-door testing before declaring the attic ready for insulation.
Can Light & Duct Boot Sealing
Signs you need it
Condensation on can light trim in summer, visible gaps around duct boots where they penetrate drywall, or conditioned air smell in the attic during HVAC operation.
What it costs in Schertz
Can light and duct boot sealing in Schertz typically ranges $800-$1,800, with fire-rated covers for non-IC-rated cans adding $45-$85 per fixture.
How we do it
We install pre-formed fire-rated covers over can lights, seal duct boots with mastic and mesh, and pressure-test the duct system where accessible to confirm no remaining leakage.
What Attic Air Sealing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Top plate and penetration sealing | $1,200 - $2,400 |
| Can light and duct boot sealing | $800 - $1,800 |
| Full attic air sealing with blower-door test | $2,200 - $4,200 |
Can attic air sealing be done without adding insulation in Schertz?
Yes - we perform standalone air sealing with blower-door verification for homeowners who want to address leakage before deciding on insulation scope, and we provide the written price for each phase separately. Call (830) 549-6646 to schedule.
What is a blower-door test and why does it matter for Schertz homes?
A blower-door test pressurizes your home to measure total air leakage in CFM50 - one number that shows how much conditioned air escapes through the envelope; in Schertz’s climate, high leakage means your AC works overtime all summer.
Wall Insulation in Schertz

Schertz’s 2×4-framed production homes were built with R-13 batts that have settled, compressed, or been disturbed by electrical and plumbing work over 15-25 years of occupancy and tenant turnover. We provide Wall Insulation using injection foam and drill-and-fill methods that don’t require removing interior drywall.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that are cold to the touch in winter, rooms with south or west exposure that overheat despite closed blinds, or energy bills disproportionate to home size.
What it costs in Schertz
Injection foam wall insulation in Schertz typically runs $3,200-$6,400 for a 2,000-square-foot home, priced by linear foot of exterior wall cavity.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam to fill the cavity without bowing drywall, then plug and texture-match the access points.
Drill & Fill Wall Insulation
Signs you need it
Existing batt insulation that has fallen to the bottom of stud bays, or walls opened during renovation where incomplete coverage is visible.
What it costs in Schertz
Drill-and-fill with dense-pack cellulose in Schertz typically ranges $2,400-$4,800 for standard production-home exterior walls, varying with cavity depth and access.
How we do it
We remove a row of siding or drill from interior, blow cellulose to 3.5 pounds per cubic foot density for no-settle performance, and verify fill with thermal imaging.
What Wall Insulation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Injection foam (exterior walls) | $3,200 - $6,400 |
| Dense-pack cellulose drill-and-fill | $2,400 - $4,800 |
| Interior wall soundproofing | $1,800 - $3,600 |
Will injection foam damage my walls in Schertz?
No - we use slow-rise formulations specifically selected for existing 2×4 framing, and we verify pressure limits during injection to prevent drywall bowing; any access holes are plugged and textured to match. Call (830) 549-6646 for a written scope.
Can you insulate walls without removing drywall in Schertz?
Yes - our drill-and-fill and injection methods access wall cavities through small exterior or interior holes, making full-wall insulation practical for finished homes built during Schertz’s 2000s construction boom.
Attic Cleaning & Rodent Proofing in Schertz

Schertz’s mature oak canopy and proximity to greenbelts create sustained rodent pressure, and the 2000s-era homes with minimal air sealing provide easy attic access through soffit gaps and roofline penetrations. We provide Attic Cleaning & Rodent Proofing as a health-and-performance service, not pest control - we remove contamination, seal entry points, and restore the attic to a condition where insulation can perform.
Attic Sanitizing & Decontamination
Signs you need it
Visible rodent droppings, urine staining on insulation or decking, or musty odors detected from ceiling penetrations that suggest biological contamination.
What it costs in Schertz
Attic sanitizing and decontamination in Schertz typically runs $1,800-$3,600 depending on contamination area, insulation removal requirements, and decking replacement needs.
How we do it
We remove contaminated insulation under HEPA containment, apply enzyme-based sanitizer to affected decking, and provide photo documentation of the cleaned surface before any restoration work.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in ceilings, visible gnaw marks on fascia or soffits, or repeated pest control visits that address population but not entry pathways.
What it costs in Schertz
Rodent proofing and exclusion in Schertz typically ranges $1,200-$2,800 for a standard production home, with complex rooflines or multiple entry points at the higher end.
How we do it
We inspect the roofline, soffits, vents, and foundation with photo documentation, seal all entry points with rodent-resistant materials, and install vent screens where missing or damaged.
What Attic Cleaning & Rodent Proofing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic sanitizing and decontamination | $1,800 - $3,600 |
| Rodent proofing and exclusion | $1,200 - $2,800 |
| Full attic restoration (cleaning + proofing + insulation) | $4,200 - $8,400 |
Do you handle live rodents in Schertz attics?
No - we partner with licensed pest control for active infestations and perform our work after they confirm the population is cleared; our scope is sealing, cleaning, and restoring the attic envelope. Call (830) 549-6646 to coordinate timing.
How do I prevent rodents from returning to my Schertz attic?
Exclusion is the permanent solution - we seal every entry point larger than 1/4 inch with rodent-proof materials and provide you the photo record of what was sealed, where, and with what.
Home Energy Audit in Schertz

Schertz homeowners who bought 2000s-era production homes often lack any baseline understanding of where conditioned air escapes or how their envelope performs under pressure. We provide Home Energy Audit services that measure actual performance with blower-door testing and thermal imaging, delivering a written report with prioritized recommendations and fixed prices for each measure.
Blower Door Test
Signs you need it
High utility bills with no obvious cause, rooms that never reach set temperature, or planning major envelope work and wanting a before-and-after performance baseline.
What it costs in Schertz
A standalone blower-door test with written report in Schertz typically runs $350-$550, or is included at no additional charge when bundled with air sealing or insulation work.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, and measure CFM50 along with infrared imaging to locate the largest leakage paths.
Thermal Imaging Inspection
Signs you need it
Visible temperature variation on walls or ceilings, suspicion of missing insulation in finished areas, or post-work verification that insulation was installed completely.
What it costs in Schertz
Thermal imaging inspection in Schertz typically ranges $250-$450 as a standalone service, or is included with our full energy audit package.
How we do it
We scan interior and exterior surfaces with a calibrated FLIR camera during heating or cooling season, annotate images with surface temperatures and probable causes, and include them in your written report.

FAQs About Insulation in Schertz
Most attic insulation retrofits and crawl space encapsulations in Schertz do not require permits when no structural or electrical changes are made; we verify permit requirements before starting any job and include that confirmation in your written scope. If your HOA has exterior modification rules, we provide the product data sheets and installation specifications they typically request.
We answer calls with a live person 24/7 and typically schedule assessments within 48 hours for Schertz addresses; emergency situations like post-storm water intrusion or failed HVAC related to envelope failure are prioritized same-day when possible. Your written price arrives within 24 hours of the assessment.
Schertz’s production-built homes from the 2000s were framed with minimal attention to envelope tightness, and blowing new insulation over leaky top plates or can lights simply filters your conditioned air into the attic - we measure this with a blower-door test and seal first so the insulation you pay for actually performs.
