Insulation in Schertz, TX
Most Schertz homes built between 2002 and 2022 were insulated to the bare IECC minimum - typically R-30 in the attic, well below the R-49 recommended for Climate Zone 2 - and the combination of 150°F summer attic heat plus air-sealing shortcuts at top plates and can lights produces energy bills that regularly surprise new homeowners. We start every job with a blower-door test to measure exactly how much conditioned air your envelope is losing, seal every penetration we find, then insulate - never the reverse. For a written price before any work starts, call us at (830) 420-0953.
Why Schertz Homes Are Different
Schertz sits at the intersection of FM 3009 and IH-35, and virtually every residential subdivision went up in the post-2000 boom - DR Horton, Lennar, Centex - built fast and sold faster to military families rotating through JBSA-Randolph. Those buyers often accepted builder-grade insulation without inspection, then PCS’d out before the first full summer exposed the problem. The next owner inherits R-30 batts, unsealed top plates, and duct boots leaking into the attic.
The 2021 Winter Storm Uri freeze changed the calculus. Homes that had never struggled with cold suddenly couldn’t retain heat, and we saw a spike in calls from Schertz homeowners who’d never considered insulation before. Summers here push attic temperatures above 150°F from June through September, so the same envelope flaws that bled heat in February bleed refrigerated air all summer long. The housing stock is young enough that homeowners assume it’s fine - and wrong enough that the fix is usually dramatic.
Our Main Schertz Services
Schertz homeowners call us most often for attic work and spray foam - the two services that address the specific failures we see in this market.
Attic Insulation in Schertz
We upgrade underperforming R-30 builder-grade installations to R-49 or R-60 using Owens Corning or Johns Manville blown-in systems, always after air sealing is complete. In Schertz’s 150°F attics, the difference between code-minimum and properly installed R-49 is measurable on the next CPS Energy bill. Every attic job includes before-and-after blower-door numbers so you can verify the air-sealing result. Attic Insulation in Schertz covers our full process and pricing.

Spray Foam Insulation in Schertz
Closed-cell spray foam at the roof deck turns the attic into conditioned space - the right solution for Schertz homes with HVAC equipment in the attic that struggles against extreme heat. We use Icynene and Demilec products, applied by background-checked technicians after a written scope is signed. The air-sealing value of foam is built in; we still test with a blower door to document the result. Spray Foam Insulation in Schertz has full details.

Blown-In Insulation in Schertz
For cost-effective upgrades to existing attics, blown-in fiberglass or cellulose adds R-value without the premium of foam. We use Knauf and GreenFiber materials, installed to proper depth after sealing all penetrations. In Schertz’s tract homes, this is often the fastest path from R-30 to R-49 with documented results. Blown-In Insulation in Schertz explains our installation standards.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Schertz

Schertz’s rapid-build subdivisions often skipped proper crawl space moisture management, leaving dirt-floored spaces with thin 6-mil poly sheeting that degrades within five years. The clay soils around FM 3009 hold water, and seasonal humidity wicks upward into floor joists, insulation, and subflooring. Crawl Space Encapsulation & Vapor Barrier addresses this at the source: sealing the ground, insulating the perimeter, and controlling humidity so your crawl space stops working against your HVAC system.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, visible mold on joists, or a musty smell that enters the living space through floor gaps.
What it costs in Schertz
Most vapor barrier installations in Schertz run $1,200 to $2,800 depending on crawl space square footage and whether existing degraded poly needs removal first.
How we do it
We remove old sheeting, grade the dirt floor for drainage, then install 12-mil reinforced polyethylene with sealed seams and mechanical fastening to walls.
Crawl Space Encapsulation
Signs you need it
Your floors are cold in winter despite good attic insulation, humidity readings in the crawl space stay above 70%, or you’ve had rodent activity in the joist bays.
What it costs in Schertz
Full encapsulation with sealed vapor barrier, perimeter wall insulation, and dehumidifier typically ranges $4,500 to $8,500 for Schertz homes under 2,500 square feet.
How we do it
We seal all vents, install rigid foam board on perimeter walls, lay sealed vapor barrier across the entire floor and up walls, then size and install a dedicated dehumidifier with condensate pump.
What Crawl Space Encapsulation & Vapor Barrier Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Vapor barrier replacement (12-mil poly) | $1,200 - $2,800 |
| Full encapsulation with dehumidifier | $4,500 - $8,500 |
| Crawl space insulation (floor joist batts or rigid foam) | $2,000 - $4,500 |
How long does crawl space encapsulation take in Schertz?
Most Schertz jobs finish in two to three days: one day for prep and barrier installation, one for insulation and dehumidifier setup, plus any needed drying time. We schedule around weather since the crawl space needs to be accessible and relatively dry when we start.
Will encapsulation help with musty smells inside the house?
Yes - the musty smell comes from mold and mildew off-gassing in damp crawl spaces, and sealing the moisture source typically eliminates indoor odor within two weeks of dehumidifier operation. Call (830) 420-0953 for a free crawl space assessment.
Radiant Barrier Installation in Schertz

Schertz attic temperatures exceed 150°F for four months straight, and standard insulation alone can’t block radiant heat transfer from the roof deck to your ductwork and ceiling plane. A properly installed radiant barrier reflects that infrared energy back toward the roof, reducing attic temperatures by 20-35°F and cutting the load on your HVAC system. Radiant Barrier Installation is the highest-ROI upgrade we offer for Schertz’s climate, especially in homes with dark shingles and minimal existing shade.
Attic Radiant Barrier
Signs you need it
Your ducts sweat in summer, upstairs rooms stay 8-12°F hotter than downstairs, or your AC runs continuously from 2 PM to sunset without cycling.
What it costs in Schertz
Radiant barrier installation in Schertz attics typically runs $1,500 to $3,200 depending on roof pitch, accessibility, and whether we install foil or spray-applied coating.
How we do it
We staple perforated aluminum foil across rafter bottoms or spray low-emissivity coating directly to the roof deck underside, ensuring continuous coverage without gaps at hips and valleys.
Radiant Barrier & Ventilation
Signs you need it
Your attic has inadequate soffit or ridge ventilation, you see moisture staining on roof decking, or the radiant barrier you want needs proper airflow to perform.
What it costs in Schertz
Combined radiant barrier plus ventilation correction in Schertz ranges $2,800 to $5,500, with ridge vent installation and baffle installation at soffits.
How we do it
We calculate net free ventilation area per code, install baffles to maintain intake pathways over new insulation, then add ridge vent or powered ventilation as specified before barrier installation.
What Radiant Barrier Installation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Foil radiant barrier (stapled to rafters) | $1,500 - $3,200 |
| Spray-applied radiant barrier coating | $2,200 - $4,500 |
| Radiant barrier with ventilation upgrade | $2,800 - $5,500 |
Does radiant barrier work with existing insulation?
Yes - radiant barrier complements rather than replaces insulation, reflecting heat before it reaches your R-value material; we install it after air sealing and before adding any new blown-in layers.
How much can radiant barrier lower my Schertz cooling bill?
Most Schertz homeowners see 10-25% summer cooling reduction, with the highest savings in homes with dark roofs, poor attic ventilation, or ductwork in the attic; exact savings depend on your current envelope condition. Call (830) 420-0953 for a free assessment with written pricing.
Insulation Removal & Replacement in Schertz

The same builder-grade fiberglass batts installed in Schertz’s 2002-2022 tract homes compress, shift, and collect moisture over fifteen to twenty years, especially when attic air leaks allow humid summer air to condense against cool ceiling drywall. We remove failed insulation only after testing for asbestos in pre-1990 materials, then install new material to current R-49 standards with full air sealing first. Insulation Removal & Replacement includes documented photo records of every stage.
Contaminated Insulation Removal
Signs you need it
Your attic insulation shows rodent droppings, urine staining, or mold growth that can’t be remediated in place, or you smell ammonia or mustiness through ceiling penetrations.
What it costs in Schertz
Contaminated insulation removal and disposal in Schertz runs $2,500 to $5,000 for a typical 2,000-square-foot home, with HEPA containment and proper waste handling included.
How we do it
We establish negative air pressure with HEPA filtration, remove bagged contaminated material through contained chutes, then apply EPA-registered sanitizer to exposed framing before any new insulation goes in.
Insulation Replacement
Signs you need it
Your existing insulation has settled below joist tops, shows water staining from past roof leaks, or was installed before 2010 at R-30 or below.
What it costs in Schertz
Full removal of old material plus replacement with R-49 blown-in fiberglass typically ranges $3,500 to $7,500 in Schertz homes, depending on attic square footage and accessibility.
How we do it
We extract old material with vacuum equipment, inspect and photograph the deck condition, seal all air leaks, then install new Owens Corning or Johns Manville blown-in to proper depth with ruler markers.
What Insulation Removal & Replacement Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Contaminated insulation removal (HEPA containment) | $2,500 - $5,000 |
| Standard insulation removal and disposal | $1,500 - $3,500 |
| Removal plus R-49 replacement with air sealing | $3,500 - $7,500 |
Do I have to leave my house during insulation removal?
No - our HEPA containment and negative air machines keep living spaces isolated, though we recommend pets and sensitive individuals stay elsewhere during the loudest vacuum extraction phase.
How do I know if my old insulation has asbestos?
We test any vermiculite or pre-1990 fiberglass for asbestos before disturbing it; if present, we refer to a licensed abatement contractor and reschedule replacement after clearance. Call (830) 420-0953 to schedule inspection.
Attic Air Sealing in Schertz

Schertz’s volume-built homes were constructed with the same air-sealing shortcuts we see across central Texas: unsealed top plates where wall framing meets the attic, recessed can lights cutting holes in the thermal boundary, and flex duct boots pulled tight with gaps that leak conditioned air directly outside the envelope. A blower-door test quantifies the damage in CFM50 - cubic feet per minute at 50 Pascals of pressure - and our Attic Air Sealing protocol seals every penetration before any insulation is added, because blowing new material over a leaky attic is like adding a thicker blanket to a tent with holes in it.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test reads above 3,500 CFM50 for a home under 2,500 square feet, or you feel drafts at outlets and switches on exterior walls during winter.
What it costs in Schertz
Top plate and penetration sealing in Schertz typically runs $1,800 to $3,500, with foam and caulk sealing of all framing joints, wire holes, and pipe penetrations.
How we do it
We pull back existing insulation to expose top plates, seal all gaps with two-part foam and acoustic sealant, then restore insulation with photo documentation of sealed locations.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights are non-IC rated fixtures with visible gaps, or your HVAC airflow at registers drops significantly when the attic is hot.
What it costs in Schertz
Sealing can lights with proper covers and mastic-sealing duct boots ranges $900 to $2,200 in Schertz attics, depending on fixture count and duct configuration.
How we do it
We install fire-rated airtight covers over each can light, seal with high-temperature caulk, then apply mastic - a thick brush-on sealant - to all duct connections and boots.
What Attic Air Sealing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Top plate and penetration sealing | $1,800 - $3,500 |
| Can light and duct boot sealing | $900 - $2,200 |
| Full attic air sealing (comprehensive) | $2,500 - $5,000 |
Can air sealing alone lower my energy bill?
Yes - we’ve measured 15-30% reductions in Schertz homes where the primary problem was leakage rather than low R-value, with before-and-after blower-door readings to prove it.
How long does attic air sealing take?
Most Schertz attic air sealing jobs complete in one day for homes under 2,500 square feet, or two days for larger homes with complex duct layouts; we test with the blower door before and after. Call (830) 420-0953 for scheduling.
Wall Insulation in Schertz

The 2×4 exterior walls in Schertz’s post-2000 tract homes were typically insulated with R-13 fiberglass batts - adequate for code at the time, but leaving little margin for the compression and voids common in fast construction. With no practical way to add exterior insulation on most HOA-governed subdivisions, the solution is dense-pack injection from the interior or exterior. Wall Insulation upgrades the thermal boundary without removing drywall, using materials from Rockwool and Johns Manville that fill every cavity.
Injection Foam Wall Insulation
Signs you need it
Your walls feel cold to the touch in winter, you have wide temperature swings between rooms on the same HVAC zone, or an infrared camera shows missing insulation in stud bays.
What it costs in Schertz
Injection foam wall insulation in Schertz runs $3,500 to $7,000 for a typical 2,000-square-foot home, with two-part foam pumped through 5/8-inch holes drilled per bay.
How we do it
We drill access holes at stud-bay intervals, inject slow-rise foam under pressure to fill without bowing drywall, then plug and texture-match holes.
Drill & Fill Wall Insulation
Signs you need it
Your home has empty wall cavities from never-insulated additions, or existing batt insulation has settled below the top plate leaving a cold zone.
What it costs in Schertz
Drill and fill with dense-pack cellulose or fiberglass in Schertz ranges $2,800 to $5,500 depending on wall square footage and exterior finish type.
How we do it
We remove siding or drill through interior drywall at each bay, blow material to 3.5 pounds per cubic foot density for cellulose, then restore all surfaces.
What Wall Insulation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Injection foam (interior or exterior access) | $3,500 - $7,000 |
| Dense-pack drill and fill (cellulose or fiberglass) | $2,800 - $5,500 |
| Interior wall soundproofing (batt or mineral wool) | $1,500 - $3,500 |
Will wall insulation damage my drywall or siding?
We drill 5/8-inch holes that we plug and texture-match on interior, or remove and replace siding courses on exterior access - the repair is included in our scope and documented in your photo record.
Can you insulate walls without removing drywall?
Yes - injection foam and dense-pack methods both work through small access holes; we only remove drywall if we’re already doing restoration work or if the wall is open for other trades. Call (830) 420-0953 for a written assessment.
Attic Cleaning & Rodent Proofing in Schertz

Schertz’s new subdivisions pushed into former ranchland, and the rodent populations displaced by construction found shelter in the very homes being built - especially attics with unsealed eave returns and builder-grade vent screens. We clean and sanitize attics after infestation, but we always pair cleanup with exclusion because removing droppings without sealing entry points guarantees repeat business we don’t want. Attic Cleaning & Rodent Proofing ends with a documented photo record of every sealed opening.
Attic Sanitizing & Decontamination
Signs you need it
Your attic has visible rodent droppings, urine stains on insulation or decking, or a persistent odor that HVAC return pathways carry into living spaces.
What it costs in Schertz
Attic sanitizing and decontamination in Schertz ranges $1,800 to $4,000 depending on contamination extent, insulation removal needs, and square footage.
How we do it
We remove contaminated material under HEPA containment, apply enzyme-based sanitizer to all surfaces, then fog with disinfectant before any new materials are installed.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in walls or attic at night, see gnaw marks at soffit vents, or have had repeated pest control visits that never addressed structural entry points.
What it costs in Schertz
Rodent proofing and exclusion for Schertz homes typically runs $1,200 to $3,200, with metal screening, concrete patching, and one-way exit devices at active entry points.
How we do it
We inspect every roofline penetration, install 1/4-inch hardware cloth over vents, seal eave returns with metal and foam, and install one-way doors at active burrows before final sealing.
What Attic Cleaning & Rodent Proofing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic sanitizing and decontamination | $1,800 - $4,000 |
| Rodent proofing and exclusion | $1,200 - $3,200 |
| Full attic restoration (cleanup + proofing + insulation) | $4,500 - $9,500 |
How do I know if rodents are in my attic right now?
Listen for scratching after sunset, check for droppings near attic hatches, and look for gnawed plastic or insulation - if you see daylight through eave returns, that’s an entry point whether rodents are present today or not.
Will pest control handle the exclusion, or do I need a contractor?
Pest control sets traps and bait; structural exclusion requires ladder work, roofing knowledge, and proper materials - we coordinate with your pest company but handle the building envelope permanently. Call (830) 420-0953 for a written scope.
Home Energy Audit in Schertz

Schertz homeowners who’ve never had an energy audit are often surprised by what a blower-door test reveals: 4,000+ CFM50 in a 2,000-square-foot home built in 2010, meaning conditioned air is escaping at the rate of a fully open window. Our Home Energy Audit documents every thermal and pressure boundary flaw with infrared imagery, duct leakage testing, and combustion safety checks - the evidence-based starting point for any insulation investment in a Schertz home.
Blower Door Test
Signs you need it
You’ve never had a measured air leakage test, your energy bills seem high for your home’s size and age, or you’re considering insulation work and want baseline data.
What it costs in Schertz
A standalone blower-door test in Schertz runs $350 to $600, or is credited toward any insulation work scheduled within 30 days of the audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 while walking the house with a smoke pencil to locate leak points.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach set temperature, suspect missing wall insulation, or need visual documentation of envelope flaws for HOA or contractor disputes.
What it costs in Schertz
Thermal imaging included with a full audit runs $450 to $750 in Schertz, with digital report and annotated images delivered within 48 hours.
How we do it
We scan all exterior walls, ceilings, and ductwork with a FLIR camera during blower-door depressurization to make temperature anomalies visible and locatable.
What Home Energy Audit Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Blower-door test (standalone) | $350 - $600 |
| Full home energy audit with thermal imaging | $450 - $750 |
| Duct leakage test (additional) | $250 - $450 |
How long does a home energy audit take?
Most Schertz audits take three to four hours including setup, testing, and a walkthrough of preliminary findings; you receive the full report with photos within two business days.
Will the audit tell me exactly what to fix first?
Yes - we prioritize repairs by cost-effectiveness and safety, with estimated savings for each measure, so you can phase work according to budget rather than guessing. Call (830) 420-0953 to schedule; audits are credited toward work.

FAQs About Insulation in Schertz
Most attic insulation and air sealing in Schertz does not require a permit, but crawl space encapsulation and any electrical modifications for dehumidifiers may need city approval; we handle permit research as part of our written scope before work begins.
We answer calls with a live person 24/7 and typically schedule assessments within one business day; emergency situations like post-storm water intrusion in crawl spaces are prioritized for same-day response when possible.
Most Schertz HOAs regulate exterior appearance and work hours rather than attic modifications, but we review your HOA guidelines before proposing any exterior-access wall insulation or visible ventilation changes to ensure compliance.

What Schertz Customers Say
"They air-sealed the attic floor before insulating and showed me the blower-door number before and after. The upstairs is finally the same temperature as downstairs."
- Marisol D."Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
- Ainsley P."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.
