Insulation in Schertz, TX
Most Schertz homes built between 1995 and 2010 were delivered with minimum-code blown fiberglass that has settled to roughly half its original R-value, making attic temperatures spike past 150°F and utility bills climb every summer. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in, with a written price before work starts and documented blower-door numbers after. For Crawl Space Encapsulation & Vapor Barrier and the full envelope service line, call (830) 243-6352. Dispatch and scheduling run from our San Antonio office; crews serve Schertz locally.
Why Schertz Homes Are Different
Schertz’s housing stock is unusually homogeneous, almost entirely 1990s-2010s slab-on-grade tract homes built by DR Horton and KB Home along corridors like Schertz Parkway and FM 1518. These houses have vented attics, low- to mid-pitch roofs, and builder-grade R-30 fiberglass batts or blown-in that compresses and settles. Pre-2010 builds predate the stricter IRC energy codes, so they lack the air-sealing detail that newer homes require.
The climate here sits in a transition zone between humid Gulf Coast air and drier Hill Country conditions, producing prolonged summers with frequent triple-digit days. Attic temperatures routinely exceed 150°F, and the 2021 Winter Storm Uri exposed pipe-freeze gaps that had gone unnoticed for years. Military families cycling through JBSA-Randolph on short PCS orders often deferred upgrades, meaning many homes near Universal City Road and FM 1518 still carry their original 1998-vintage insulation, now reading at an effective R-15 or lower.
Our Main Schertz Services
Schertz homeowners call us most often for attic work and spray foam; here is what those jobs involve locally.
Attic Insulation in Schertz
Attic insulation in Schertz means dealing with vented attics packed with settled blown fiberglass that no longer meets its labeled R-value. We remove or supplement the existing layer, seal top plates and can lights first, then install Owens Corning or Johns Manville products to the correct depth for this climate zone. Every job gets a written price upfront and a documented photo record at completion. Attic Insulation in Schertz
Spray Foam Insulation in Schertz
Spray foam insulation in Schertz is the right choice for homeowners who want to convert a vented attic to conditioned space or seal wall cavities in additions built after the original tract home. We use open-cell and closed-cell products from Icynene and Demilec, applied after blower-door testing establishes the baseline air leakage rate. The Haven Standard applies: written scope, written price, written warranty before any work starts. Spray Foam Insulation in Schertz
Blown-In Insulation in Schertz
Blown-in insulation in Schertz is the most common retrofit for volume-built homes where the original fiberglass has compressed below effective R-30. We blow GreenFiber cellulose or Knauf fiberglass over a fully sealed attic floor, never over unsealed top plates or penetrations. The result is measured: before-and-after blower-door numbers show the actual air leakage reduction. Blown-In Insulation in Schertz

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Schertz
Schertz’s slab-on-grade construction means most homes have no basement, but the minority with crawl spaces face the same Gulf Coast humidity that pushes moisture through vented dirt floors. In neighborhoods near Cibolo Creek and the lower-lying sections off FM 1518, we’ve found crawl spaces with relative humidity sustained above 80 percent, rotting floor joists and breeding mold that migrates upward into living spaces. Crawl Space Encapsulation & Vapor Barrier is the fix: we seal the ground and walls, install mechanical dehumidification where needed, and deliver before-and-after moisture readings in writing.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or floors above that feel cold and damp even when the heat runs.
What it costs in Schertz
A 6-mil to 20-mil vapor barrier installation in Schertz typically runs $1,200 to $3,500 depending on crawl space square footage and whether we need to grade the dirt floor first.
How we do it
We clear debris, lay overlapping polyethylene sheeting sealed at seams and walls, and tape penetrations so ground moisture cannot reach the framing.
Crawl Space Encapsulation
Signs you need it
You smell mustiness on the first floor, see insulation falling from between joists, or your HVAC ducts in the crawl space sweat and drip.
What it costs in Schertz
Full encapsulation with closed-cell spray foam on walls, a reinforced vapor barrier on the floor, and a dehumidifier typically ranges from $4,500 to $9,000 in Schertz homes.
How we do it
We seal foundation vents, insulate walls with closed-cell foam, install the floor membrane, and add a condensate-pumped dehumidifier sized to the cubic footage.
What Crawl Space Encapsulation & Vapor Barrier Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Vapor barrier (6-20 mil, floor only) | $1,200 - $3,500 |
| Full encapsulation with dehumidifier | $4,500 - $9,000 |
| Crawl space insulation (joist or wall) | $1,500 - $4,000 |
Will encapsulation stop mold in my Schertz crawl space?
Encapsulation stops the moisture source that feeds mold, but active mold must be remediated first; we document pre-existing conditions with photos before sealing anything.
How long does crawl space work take in Schertz?
Most vapor barrier jobs finish in one day; full encapsulation with foam and dehumidification takes two to three days, with a written completion schedule before we start.
Radiant Barrier Installation in Schertz
Schertz’s 150°F+ attic temperatures make radiant heat gain the dominant cooling load in most homes, especially the south-facing pitches common in Savannah and Schertz Parkway subdivisions. A radiant barrier reflects infrared radiation before it reaches your insulation layer, reducing the delta-T that your HVAC must overcome. Radiant Barrier Installation is most cost-effective here because the existing insulation is already compromised by settlement, so the barrier addresses a heat path that fiberglass alone cannot stop.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms run 8-12 degrees hotter than downstairs, your AC cycles constantly after 2 p.m., or your roof decking is too hot to touch from below.
What it costs in Schertz
Radiant barrier foil laid over existing attic insulation in Schertz typically costs $1,000 to $2,500 depending on attic square footage and accessibility.
How we do it
We staple perforated aluminum foil across rafter bottoms or lay it over the attic floor, maintaining ventilation paths so moisture does not trap.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing soon, your attic has no floor for overlay installation, or you want the most durable attachment method for a long-term solution.
What it costs in Schertz
Spray-applied radiant barrier on the roof deck during a re-roof or retrofit runs $1,500 to $3,500 in Schertz, with higher costs for steep pitches.
How we do it
We spray a low-emissivity coating directly to the underside of roof decking, creating a bonded radiant barrier that won’t tear or shift.
What Radiant Barrier Installation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Foil radiant barrier (attic floor or rafters) | $1,000 - $2,500 |
| Spray-applied roof deck barrier | $1,500 - $3,500 |
| Radiant barrier with attic air sealing | $2,000 - $4,500 |
Does radiant barrier work with settled fiberglass?
Yes, it works especially well because the barrier addresses radiant heat that compromised fiberglass cannot block; we often pair it with insulation replacement for full performance.
Will a radiant barrier affect my cell signal or WiFi?
Perforated foil barriers have no measurable effect; solid foil can attenuate signals slightly, so we use perforated products or spray coatings unless the attic is non-residential.
Insulation Removal & Replacement in Schertz
Schertz’s volume-built homes from the 1990s and 2000s contain blown fiberglass that has settled, compacted, and in some cases been contaminated by roof leaks or rodent activity. In the Universal City Road corridor near JBSA-Randolph, we’ve pulled out insulation that homeowners didn’t know was soaked from a three-year-old pipe boot leak. Insulation Removal & Replacement starts with a documented photo record of what we find, then a written price for removal, disposal, and replacement with new material.
Attic Insulation Removal
Signs you need it
Your insulation is flat and compacted, shows water stains, or has dark spots from dust filtration where air leaked through.
What it costs in Schertz
Attic insulation removal and disposal in Schertz typically runs $1,000 to $2,500 depending on volume, access, and whether the material is bagged or vacuum-extracted.
How we do it
We use commercial vacuums with HEPA filtration, bag the material in the attic to avoid contamination, and dispose per Texas environmental guidelines.
Contaminated Insulation Removal
Signs you need it
You smell urine in the attic, see droppings, or have had confirmed rodent activity that has saturated the insulation with biological material.
What it costs in Schertz
Contaminated removal with PPE, sanitizing, and deodorizing before replacement typically costs $2,500 to $5,500 in Schertz attics.
How we do it
We suit in full protection, remove contaminated material, apply enzymatic sanitizer to decking and joists, and verify with moisture meters before installing new insulation.
What Insulation Removal & Replacement Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Standard attic insulation removal | $1,000 - $2,500 |
| Contaminated insulation removal + sanitize | $2,500 - $5,500 |
| Removal + replacement with new R-38 to R-49 | $3,500 - $7,500 |
Can you remove insulation without tearing up my ceiling?
Yes, we access through the attic hatch or existing openings; ceiling drywall stays intact unless there’s hidden damage we document with photos first.
How do I know if my insulation is contaminated?
Dark, compacted areas with odor or droppings are clear signs; we inspect and photograph before quoting, so you see what we see before any work starts.
Attic Air Sealing in Schertz
Schertz’s builder-grade homes were assembled with minimal attention to the pressure boundary, so conditioned air leaks through top plates, can light housings, and duct boots into vented attics every minute the HVAC runs. We’ve blower-door tested homes in Savannah and along FM 1518 that were losing 35 percent of conditioned air to the attic before we touched the insulation. Attic Air Sealing is always our first step, never an upsell; we seal before we insulate, and we prove the result with before-and-after blower-door numbers.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at outlets on exterior walls, see dust streaks around ceiling fixtures, or your blower-door test shows excessive leakage at the attic floor.
What it costs in Schertz
Top plate and penetration sealing in a typical Schertz tract home runs $800 to $2,000, depending on the linear footage of walls and number of penetrations.
How we do it
We foam-seal the gap between drywall and top plates, caulk wire and pipe penetrations, and install fire-rated foam around chimneys and flues.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in wind, you see insulation debris around duct boots, or thermal imaging shows hot spots at ceiling fixtures.
What it costs in Schertz
Sealing can light housings with fire-rated covers and mastic-sealing duct boots typically costs $500 to $1,500 in Schertz homes with standard HVAC layouts.
How we do it
We install pre-formed fire boxes over non-IC can lights, seal with fire-rated caulk, and apply mastic to all duct boot connections.
What Attic Air Sealing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Top plate and penetration sealing | $800 - $2,000 |
| Can light and duct boot sealing | $500 - $1,500 |
| Full attic air sealing (comprehensive) | $1,500 - $3,500 |
Do I need air sealing if I’m already adding insulation?
Yes, blowing new insulation over unsealed leaks buries the problem and makes it harder to fix later; we seal first, insulate second, always.
How much does air sealing lower my blower-door number?
Typical Schertz homes drop 20-40 percent in CFM50 after comprehensive attic sealing; we show you the before and after in writing.
Wall Insulation in Schertz
Schertz’s slab-on-grade tract homes were built with 2×4 exterior walls and minimal cavity insulation, often R-13 fiberglass batts that have sagged or been compromised by wiring and plumbing penetrations. After Winter Storm Uri, we fielded calls from homeowners in Schertz Parkway-area subdivisions who had frozen pipes in exterior walls despite running faucets, a clear sign that wall cavities were under-insulated or air-leaky. Wall Insulation for these homes means dense-packing or injection methods that don’t require tearing out drywall.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel cold to the touch in winter, you have frozen pipe history, or your home was built before 2010 with known R-13 or empty cavities.
What it costs in Schertz
Injection foam for exterior walls in a typical Schertz single-story home runs $3,000 to $6,500, with two-story homes at the higher end.
How we do it
We drill 2-inch holes at stud-bay intervals, inject slow-rise foam that fills around obstructions, then plug and texture-match the holes.
Drill & Fill Wall Insulation
Signs you need it
You want cellulose or fiberglass in walls rather than foam, or your HOA restricts foam products and requires a non-expanding alternative.
What it costs in Schertz
Drill-and-fill with dense-pack cellulose or fiberglass in Schertz walls typically costs $2,500 to $5,500 for a complete exterior wall scope.
How we do it
We drill, blow material to calculated density using a tube-and-fill method that prevents settling, then seal and finish every penetration.
What Wall Insulation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Injection foam (exterior walls) | $3,000 - $6,500 |
| Drill-and-fill cellulose or fiberglass | $2,500 - $5,500 |
| Interior wall soundproofing | $1,500 - $4,000 |
Will injection foam damage my walls?
No, slow-rise formulations exert minimal pressure; we monitor expansion and have completed thousands of injections without structural issues, documented with photos.
Can you insulate walls without removing drywall?
Yes, drill-and-fill methods access cavities through small exterior or interior holes that we patch and texture-match, leaving no visible disruption.
Attic Cleaning & Rodent Proofing in Schertz
Schertz’s mature oak canopy and proximity to greenbelts create sustained rodent pressure, and the settled fiberglass in older tract homes provides perfect nesting material. We’ve cleaned attics near Cibolo Creek where squirrels had compressed insulation into tunnel systems, and homes off FM 1518 where roof rats had accessed through unsealed eave returns. Attic Cleaning & Rodent Proofing includes removal of contaminated material, sanitizing, and exclusion work that seals the entry paths.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at night, find droppings in the attic, or smell ammonia-like odor that worsens in summer heat.
What it costs in Schertz
Attic cleanout with removal of contaminated insulation, HEPA vacuuming, and enzymatic sanitizing in Schertz typically runs $1,500 to $4,000.
How we do it
We remove all contaminated material, vacuum with HEPA filtration, apply sanitizer to all surfaces, and document with before-and-after photos.
Rodent Proofing & Exclusion
Signs you need it
You’ve had repeated pest control visits, see gnaw marks on fascia boards, or find new droppings within months of previous cleanup.
What it costs in Schertz
Rodent proofing with metal flashing, hardware cloth, and sealant at all entry points typically costs $800 to $2,500 in Schertz homes.
How we do it
We inspect the roofline, eaves, soffits, and foundation, install chew-proof barriers at every gap larger than 1/4 inch, and guarantee the exclusion.
What Attic Cleaning & Rodent Proofing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic cleanout and sanitizing | $1,500 - $4,000 |
| Rodent proofing and exclusion | $800 - $2,500 |
| Full attic restoration (cleanout + proofing + insulation) | $4,000 - $9,000 |
How do I know rodents are gone before you seal?
We set monitoring devices and verify no activity for a minimum period before sealing; trapping and exclusion are coordinated, not guessed.
Is rodent-proofing a one-time fix?
Our exclusion work carries the 365-Day Done Right Promise; if rodents re-enter through sealed points, we return and correct at no charge.
Home Energy Audit in Schertz
A home energy audit in Schertz reveals exactly where your 1990s-2010s tract home is leaking conditioned air and wasting utility dollars, with documented numbers you can act on or take to another contractor. We audit frequently in Savannah and along Schertz Parkway, where homeowners want to prioritize envelope improvements before replacing an HVAC system that is actually oversized for the real load. Home Energy Audit includes blower-door testing, thermal imaging, and a written scope with prioritized recommendations and fixed prices for each item.
Blower Door Test
Signs you need it
Your utility bills are rising without rate changes, rooms have uneven temperatures, or you’re considering HVAC replacement and want to right-size the equipment.
What it costs in Schertz
A standalone blower-door test with written report in Schertz typically costs $300 to $600; it’s credited toward work if you proceed within 90 days.
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.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls, want to locate air leaks behind drywall, or need documentation for an insurance claim after storm damage.
What it costs in Schertz
Thermal imaging as part of a full audit or standalone inspection runs $200 to $500 in Schertz, depending on square footage and reporting detail.
How we do it
We scan with a FLIR camera during blower-door depressurization to make temperature anomalies visible, then mark findings on floor plans.
What Home Energy Audit Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Blower-door test with written report | $300 - $600 |
| Full home energy audit (blower door + thermal + duct test) | $400 - $800 |
| Thermal imaging inspection | $200 - $500 |
Will an audit tell me if I need new insulation?
Yes, the blower-door number and thermal images show exactly where insulation is missing, compressed, or bypassed by air leakage; the report prioritizes fixes by cost-effectiveness.
How long does a home energy audit take?
Plan on two to three hours for a full audit; we schedule morning or afternoon slots, and you receive the written report with fixed prices within 48 hours.
