Insulation in Schertz, TX
Crawl space encapsulation and vapor barrier installation in Schertz typically runs $3,500-$7,500 for a full encapsulation, with most homes in the 1,400-2,400 square foot range falling in the middle of that band. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in - sealed first, then insulated, in that order. If your Schertz home was built between 2000 and 2020 in one of the production tracts along IH-35, there’s a strong chance your crawl space has the original thin polyethylene vapor barrier, if anything at all, and no sealing at the rim joists. Call (737) 227-6219 and we’ll give you a written price before any work starts.
Why Schertz Homes Are Different
Schertz sits in a hot-humid to hot-dry transition zone where attic temperatures push past 145°F in July and August, making thermal performance the dominant energy driver for local homeowners. The explosive tract-home growth along IH-35 - thousands of homes built by DR Horton, Lennar, and similar production builders from roughly 2000 to 2020 - left most of the housing stock with builder-grade fiberglass batts at minimum Texas energy code R-values, with quality control that varied block to block.
Now that these homes are 10-20 years old and cycling through a large military-transient rental market tied to adjacent JBSA-Randolph, we’re seeing the same patterns repeatedly: compressed or settled batts below rated R-value, radiant-barrier decking that’s degraded, and recessed can lights that were never capped or air-sealed. The 2021 Winter Storm Uri freeze exposed how these same assemblies fail during hard freezes, creating dual-season urgency for proper envelope work. Homes near JBSA-Randolph built in the early-to-mid 2000s are especially prone to bypasses at top plates and unsealed penetrations that dump conditioned air directly into superheated attics.
Our Main Schertz Services
Schertz homeowners call us most often for attic work and spray foam - here is what each job looks like locally.
Attic Insulation in Schertz
Most Schertz attics we enter have original fiberglass batts that have compressed to R-19 or below, well under the R-38 to R-60 range that performs in this climate. We start with a blower-door test to establish baseline leakage, seal all bypasses, then install the appropriate insulation - blown cellulose, fiberglass, or spray foam depending on the roof deck and your budget. Every job gets a written price first and a documented photo record at completion. Attic Insulation in Schertz covers full project details and pricing.
Spray Foam Insulation in Schertz
Spray foam makes sense in Schertz for sealed attics, rim joists, and crawl space walls where fiberglass can’t form an air barrier. We use open-cell and closed-cell products from Owens Corning, Johns Manville, and other manufacturers - no proprietary lock-in - and we never spray over an unsealed surface. The before-and-after blower-door numbers show you exactly what changed. Spray Foam Insulation in Schertz has full specifications.
Blown-In Insulation in Schertz
Blown-in fiberglass or cellulose is the most cost-effective way to bring a Schertz attic up to performance standard when the existing batts are compressed but not contaminated. We remove or lift the old material, seal the attic floor completely, then blow to the target depth with a marked ruler photo for your record. Blown-In Insulation in Schertz explains depth targets and material options.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Schertz
Schertz’s 2000s-2010s production homes were often built with vented crawl spaces and thin 6-mil polyethylene vapor barriers, if any barrier was installed at all. In the local climate, that means summer humidity migrates upward through the floor system, while winter cold snaps - like the 2021 Uri freeze - risk pipe freeze when rim joists leak air. Crawl Space Encapsulation & Vapor Barrier is the service we recommend most often for Schertz homes with musty first floors, cold tile, or visible moisture below.
Crawl Space Vapor Barrier
Signs you need it
You notice damp or musty odors from the first floor, visible condensation on ductwork, or the existing plastic sheeting is torn, thin, or missing entirely.
What it costs in Schertz
A standalone vapor barrier replacement in Schertz typically runs $1,200-$2,800 depending on crawl space square footage and access difficulty.
How we do it
We remove the old material, grade the soil for drainage, seam-seal a new 10-20 mil reinforced polyethylene layer at all overlaps, and terminate it at the piers and walls with mechanical fastening.
Crawl Space Encapsulation
Signs you need it
You’re seeing mold on floor joists, experiencing hardwood floor cupping, or running a dehumidifier constantly in summer without resolving the moisture source.
What it costs in Schertz
Full crawl space encapsulation in Schertz generally ranges from $3,500-$7,500 for homes between 1,400 and 2,400 square feet, with larger or conditioned crawl spaces at the higher end.
How we do it
We seal all vents, install rigid foam board on foundation walls, lay a sealed vapor barrier across the floor and up the walls, then add a dehumidifier sized to the space with a condensate pump to the exterior.
What Crawl Space Encapsulation & Vapor Barrier Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Vapor barrier replacement (6-10 mil) | $1,200 - $2,800 |
| Full encapsulation with wall foam | $3,500 - $7,500 |
| Encapsulation + dehumidifier install | $5,000 - $9,500 |
Is crawl space encapsulation worth it in Schertz?
Yes - the combination of summer humidity and winter freeze risk in Schertz means unsealed crawl spaces actively damage floor systems and waste energy. We document the before-and-after moisture readings so you can verify the result. Call (737) 227-6219 for a written price - estimates are free.
How long does crawl space encapsulation take?
Most Schertz encapsulations are completed in 2-3 days, with larger or conditioned crawl spaces running up to 4 days. We deliver the written scope and warranty before anyone starts, per Haven Standard Clause 1.
Radiant Barrier Installation in Schertz
Schertz attic temperatures routinely exceed 145°F in summer, and many production-built homes from the 2000s-2010s came with radiant-barrier decking that has degraded, delaminated, or was never properly installed. When that reflective surface fails, the attic becomes a radiant oven that forces your HVAC to run longer and harder. Radiant Barrier Installation restores that critical reflective layer.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 p.m., your AC runs continuously on summer afternoons, or you can see degraded or missing radiant barrier on the roof deck from the attic hatch.
What it costs in Schertz
Attic radiant barrier installation in Schertz typically costs $1,500-$3,500 for a standard single-story home, with two-story homes and complex rooflines toward the higher end.
How we do it
We staple double-sided radiant barrier foil across the bottom of rafters or directly to the roof deck, maintaining required air gaps at soffits and ridge vents, then photograph the completed installation for your record.
Radiant Barrier & Ventilation
Signs you need it
Your attic has no radiant barrier and insufficient ventilation, with bathroom fans dumping moist air into the space or soffit vents blocked by insulation.
What it costs in Schertz
Radiant barrier plus ventilation correction in Schertz runs $2,500-$5,000 depending on the number of bath fans to duct, soffit venting to clear, and whether powered attic vents are needed.
How we do it
We install the radiant barrier, then add or correct soffit baffles, duct bath fans to exterior terminals, and verify airflow with a smoke pencil - all documented in your photo record.
What Radiant Barrier Installation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic radiant barrier (foil on rafters) | $1,500 - $3,500 |
| Radiant barrier + ventilation correction | $2,500 - $5,000 |
| Roof deck replacement with radiant barrier sheathing | $4,000 - $8,500 |
Does radiant barrier really work in Schertz’s humidity?
Yes - radiant barrier reflects radiant heat, it does not rely on air sealing, so humidity does not reduce its performance. We see attic temperature drops of 20-35°F in Schertz homes after proper installation. Call (737) 227-6219 for a free estimate with written pricing.
Can radiant barrier be added to existing insulation?
Absolutely - we install it above the insulation on rafters or below on the roof deck, never compressing the existing material. The blower-door test shows whether air sealing is also needed before we proceed.
Insulation Removal & Replacement in Schertz
Schertz’s large military-transient rental market means attics often accumulate multiple layers of compressed, damaged, or contaminated insulation between tenants. We’ve removed rodent-soiled batts, water-damaged cellulose, and DIY installations that blocked soffit vents entirely. Insulation Removal & Replacement starts with a contamination assessment and written disposal plan.
Contaminated Insulation Removal
Signs you need it
You smell ammonia or mustiness from the attic, see rodent droppings, or find discolored, wet, or mold-stained insulation when you check the hatch.
What it costs in Schertz
Contaminated insulation removal in Schertz runs $2,000-$4,500 depending on the attic square footage, contamination level, and whether HEPA containment is required.
How we do it
We establish negative air containment, remove the material with commercial vacuums into sealed bags, apply antimicrobial treatment to exposed framing, and provide photos of the clean deck before any new insulation goes in.
Insulation Replacement
Signs you need it
Your insulation is compressed below half its original thickness, has visible gaps and voids, or was installed with the vapor barrier facing the wrong direction.
What it costs in Schertz
Insulation replacement in Schertz after removal typically adds $2,500-$5,500 for blown-in fiberglass or cellulose to R-38, with spray foam at a higher range.
How we do it
We air seal the attic floor completely after removal, verify with a blower-door test, then install new material to the marked depth with a ruler photo for your documented record.
What Insulation Removal & Replacement Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Contaminated insulation removal | $2,000 - $4,500 |
| Standard insulation removal (non-contaminated) | $1,000 - $2,500 |
| Removal + replacement with blown-in to R-38 | $3,500 - $8,000 |
Do I have to leave during insulation removal?
No - for standard removal, we contain the attic space and run negative air machines. For heavy contamination, we may recommend you step out for 4-6 hours during the most intensive phase. We discuss this in the written scope before work starts.
How do I know if my insulation is contaminated?
Dark staining, compressed areas with a urine smell, or visible droppings are clear indicators. We inspect and photograph the condition during our free estimate - call (737) 227-6219 to schedule.
Attic Air Sealing in Schertz
Schertz homes built near JBSA-Randolph in the early-to-mid 2000s frequently have recessed can lights that were never capped or air-sealed, plus top plate gaps and duct boot leaks that dump conditioned air directly into 150°F attics. This is the single most cost-effective upgrade for many Schertz homeowners, and we never install insulation over an unsealed attic floor. Attic Air Sealing is always our first step.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage, you feel drafts at interior wall tops, or you can see daylight through gaps at the attic floor perimeter.
What it costs in Schertz
Top plate and penetration sealing in Schertz typically runs $1,200-$2,800 for a standard attic, with larger homes or extensive plumbing/electrical penetrations toward the higher end.
How we do it
We seal all top plates with fire-rated caulk or foam, box out recessed lights with airtight covers, seal around chimneys and flues with proper clearances, then re-test with the blower door to verify the reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights flicker when the attic is windy, you feel hot attic air around ceiling fixtures, or your ductwork shows dust streaks at connections indicating leakage.
What it costs in Schertz
Can light sealing and duct boot sealing in Schertz costs $800-$2,200 depending on the number of fixtures and whether ducts need mastic repair or replacement.
How we do it
We install pre-formed airtight covers over each can light, seal duct boots with mastic and mesh, pressure-test the duct system if indicated, and deliver before-and-after blower-door numbers.
What Attic Air Sealing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Top plate & penetration sealing | $1,200 - $2,800 |
| Can light & duct boot sealing | $800 - $2,200 |
| Full attic air sealing (comprehensive) | $2,500 - $5,000 |
Can attic air sealing be done without adding insulation?
Yes - it’s a standalone service, and we often recommend it first in Schertz homes where the existing insulation is in decent shape but the air leakage is severe. The blower-door test proves the value before you spend more.
How much does air sealing save on energy bills?
Most Schertz homeowners see 15-25% reduction in heating and cooling costs after proper attic air sealing, with the biggest improvements in homes with unsealed can lights and top plates. Call (737) 227-6219 for a free estimate with written pricing.
Wall Insulation in Schertz
Schertz’s 2000s-2010s production homes were built with fiberglass batts in walls, often poorly fitted around electrical boxes and plumbing stacks, creating thermal bypasses that show up on infrared cameras. Exterior walls in these homes are rarely at the performance level the R-value label suggests. Wall Insulation addresses what the original builders missed.
Injection Foam Wall Insulation
Signs you need it
Your walls feel hot to the touch in summer, rooms on the west side of the house never cool evenly, or an infrared scan shows voids and gaps in the wall cavity insulation.
What it costs in Schertz
Injection foam wall insulation in Schertz runs $3,500-$7,500 for a typical 1,800-2,400 square foot home, with two-story homes and complex wall geometries toward the higher end.
How we do it
We drill 2-inch holes at stud-bay intervals, inject slow-rise foam that fills around obstructions, patch with matching siding or interior texture, and provide thermal images showing the before-and-after cavity fill.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls have no insulation or the original batts have settled, leaving a gap at the top of the cavity that infrared imaging confirms.
What it costs in Schertz
Drill and fill with dense-pack cellulose in Schertz typically costs $2,500-$5,500 depending on wall area, access, and whether interior or exterior drilling is used.
How we do it
We access each stud bay through minimal holes, blow cellulose to the proper density to prevent settling, seal the holes with matching materials, and verify density with a wall-cavity probe.
What Wall Insulation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Drill & fill (dense-pack cellulose) | $2,500 - $5,500 |
| Injection foam (slow-rise polyurethane) | $3,500 - $7,500 |
| Exterior wall insulation with siding removal | $5,000 - $12,000 |
Can you insulate walls without removing drywall?
Yes - injection foam and dense-pack cellulose both use minimal drilling that we patch and match to existing texture or siding. Most Schertz homeowners never need interior demolition. Call (737) 227-6219 for a free assessment.
Does wall insulation help with sound?
Dense-pack cellulose and injection foam both reduce exterior noise transmission significantly; for dedicated soundproofing between interior rooms, we use Rockwool or specific acoustic assemblies. We specify the right material in the written scope.
Attic Cleaning & Rodent Proofing in Schertz
Schertz’s mature neighborhoods with established tree canopy and proximity to greenbelt corridors see regular rodent activity, and attics in rental properties near JBSA-Randolph often accumulate years of contamination between tenants. We clean, sanitize, and seal - in that order - because new insulation over soiled decking wastes money. Attic Cleaning & Rodent Proofing includes full documentation.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia or musk from the attic, see rodent droppings or urine stains on insulation, or find nesting material in soffits and eaves.
What it costs in Schertz
Attic sanitizing and decontamination in Schertz runs $1,500-$3,500 for a standard attic, with heavy contamination or large attics toward the higher end.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply EPA-registered antimicrobial treatment, and photograph the sanitized deck before any restoration work begins.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find new droppings after cleaning, or see gnaw marks at soffit vents, roof returns, or where utilities enter the structure.
What it costs in Schertz
Rodent proofing and exclusion in Schertz typically costs $800-$2,500 depending on entry point complexity, roof pitch, and whether one-way doors are needed for active eviction.
How we do it
We inspect with a camera, seal all entry points 1/4-inch and larger with rodent-proof materials, install hardware cloth over vents, and provide a written exclusion map with photos of each sealed location.
What Attic Cleaning & Rodent Proofing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic sanitizing & decontamination | $1,500 - $3,500 |
| Rodent proofing & exclusion | $800 - $2,500 |
| Full attic restoration (clean + seal + re-insulate) | $4,500 - $10,000 |
How do I know rodents are gone before you re-insulate?
We set monitoring devices, seal all entry points, and verify no activity for a minimum period before installing new insulation. The written scope specifies the timeline and verification method for your job.
Is rodent damage covered by homeowners insurance?
Most policies exclude rodent damage to insulation and wiring, though some cover entry-point repair if it’s tied to a covered peril. We document everything with photos to support any claim you choose to file. Call (737) 227-6219 for a free assessment.
Home Energy Audit in Schertz
A home energy audit in Schertz identifies exactly where your 2000s-era production home is leaking conditioned air and wasting money, with specific recommendations prioritized by cost-effectiveness. We use the same blower-door, infrared, and duct-testing equipment on audits that we use on our own jobs, so the findings are actionable - not theoretical. Home Energy Audit is where every major project should start.
Blower Door Test
Signs you need it
Your energy bills are rising without rate increases, rooms have uneven temperatures, or you’re planning insulation work and want to measure the actual improvement.
What it costs in Schertz
A standalone blower-door test in Schertz costs $300-$600, or it’s included at no charge when you proceed with recommended work from the audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure the airflow in CFM50, then walk the house with a smoke pencil to locate the largest leaks while the fan runs.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls or ceilings, have rooms that never reach set temperature, or want visual proof of envelope defects before committing to work.
What it costs in Schertz
Thermal imaging inspection in Schertz runs $250-$500 as a standalone service, or combined with a blower-door test for $400-$800 total.
How we do it
We scan all exterior walls, ceilings, and accessible framing with a FLIR camera during blower-door depressurization to make thermal bypasses visible, then deliver annotated images with temperature readings.
What Home Energy Audit Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Blower-door test (standalone) | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Full audit (blower door + thermal + duct test) | $400 - $850 |
