Insulation in Schertz, TX
Crawl space encapsulation and vapor barrier installation in Schertz typically runs $3,800-$7,200 for a full encapsulation, with most jobs completed in two days. Because Schertz’s 2000s-era production homes were built on slab or with minimal crawl space protection, moisture and humidity issues are common in neighborhoods like Fairhaven and Belmont Park. If you’re seeing musty odors, sagging insulation, or condensation under your home, call (830) 402-5240 for a free written estimate with upfront pricing.
Why Schertz Homes Are Different
Schertz is almost entirely a product of the 2000s-2015 production-builder boom along the I-35 corridor, which means the overwhelming majority of its housing was installed with minimum-code R-30 fiberglass attic insulation by national builders. That insulation was marginal on day one in a climate where attic cavities routinely hit 150°F. The city’s large military-family population tied to JBSA-Randolph drives high household turnover, leaving most homes with untouched builder-grade insulation and creating an unusually concentrated retrofit market.
Homes in subdivisions built along FM 1518 and FM 3009 during the mid-2000s rush frequently have blown fiberglass that has settled to an effective R-20 or lower. Because military renters and short-tenure owners rarely commission energy audits, these degraded assemblies go undetected until a $400 summer electric bill finally prompts a call. The occasional hard freeze, most dramatically Winter Storm Uri in February 2021, burst pipes in poorly insulated homes across the area, creating a dual-season argument for upgrading beyond builder-grade levels.
Our Main Schertz Services
Schertz homeowners call us most often for attic work and spray foam retrofits. Here is what those jobs look like locally.
Attic Insulation in Schertz
Most Schertz attics we enter still hold the original blown fiberglass installed by DR Horton or Lennar crews in 2005-2012. It has settled, compressed, and often shows rodent disturbance. We measure what’s there, seal the attic floor first, then add dense-pack cellulose or new blown fiberglass to reach R-38 or R-49. Every job gets a written price before work starts and a Documented Photo Record when we leave. Attic Insulation in Schertz covers our full process and typical pricing.

Spray Foam Insulation in Schertz
Spray foam makes sense in Schertz when homeowners want to condition their attic or seal a pier-and-beam crawl space against the humid Gulf air that pushes up through I-35. We use open-cell foam for attic roof decks and closed-cell for crawl space walls and rim joists. All foam work includes a written scope, manufacturer specs from Demilec or Icynene, and the 365-Day Done Right Promise. Spray Foam Insulation in Schertz has full details.

Blown-In Insulation in Schertz
Blown-in remains the most cost-effective attic upgrade for Schertz’s typical 1,800-2,400 square foot tract home. We remove settled fiberglass, air seal the attic floor with caulk and foam at top plates and penetrations, then blow new material, usually Owens Corning or Johns Manville fiberglass or GreenFiber cellulose, to the depth required for R-38. The job takes one day for most homes in Ashley Place or Belmont Park. Blown-In Insulation in Schertz explains material choices and pricing.

Crawl Space Encapsulation & Vapor Barrier in Schertz

Schertz’s rapid 2000s construction boom left many homes with crawl spaces that were never properly sealed against the humid South Central Texas climate. Vented crawl spaces with dirt floors and thin 6-mil vapor barriers are standard in subdivisions like Fairhaven, and the result is persistent moisture, mold-friendly conditions, and fiberglass batts that sag and degrade. Crawl Space Encapsulation & Vapor Barrier is often the only permanent fix.
Crawl Space Encapsulation
Signs you need it
Standing water after rain, musty odors entering the living space, sagging insulation between joists, or visible mold on wood framing.
What it costs in Schertz
Full crawl space encapsulation in Schertz typically runs $3,800-$7,200 depending on square footage, existing moisture damage, and whether a dehumidifier is required.
How we do it
We remove degraded insulation, grade the floor, seal all vents, install a heavy-duty reinforced liner on walls and floor, tape all seams, and install a dedicated dehumidifier with a condensate pump.
Crawl Space Vapor Barrier
Signs you need it
Dirt floor visible through torn plastic, condensation on ductwork, or humidity readings above 70% in the crawl space.
What it costs in Schertz
Vapor barrier replacement or upgrade in Schertz typically runs $1,200-$2,800 for standard installations, with thicker reinforced barriers or full-seal jobs at the higher end.
How we do it
We remove the existing thin barrier, level and prep the ground, lay 12-20 mil reinforced polyethylene with sealed seams, and extend it up foundation walls to the sill plate.
What Crawl Space Encapsulation & Vapor Barrier Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Crawl space vapor barrier (standard) | $1,200 - $2,800 |
| Crawl space encapsulation (full) | $3,800 - $7,200 |
| Dehumidifier with condensate pump | $800 - $1,500 |
How long does crawl space encapsulation take in Schertz?
Most full encapsulations take two days; vapor barrier-only jobs finish in one day. We provide a written schedule with your price before anyone arrives.
Will encapsulation help with summer humidity in Schertz?
Yes. Sealed crawl spaces with dehumidification typically hold 50-55% relative humidity year-round, protecting floor systems and indoor air quality through Schertz’s humid summers.
Radiant Barrier Installation in Schertz

Schertz attic temperatures regularly reach 140-155°F from June through August, turning under-insulated ceilings into the single largest energy loss point in the home. Production builders in neighborhoods along FM 1518 and FM 3009 rarely installed radiant barriers during the mid-2000s rush, leaving homeowners dependent on R-30 fiberglass alone against extreme radiant heat gain. Radiant Barrier Installation reflects that heat back toward the roof deck before it reaches the insulation layer.
Attic Radiant Barrier
Signs you need it
Second-story rooms that stay hot after sunset, AC running continuously from noon to 8 PM, or ductwork in the attic that feels hot to the touch.
What it costs in Schertz
Attic radiant barrier installation in Schertz typically runs $1,500-$3,200 depending on attic square footage, accessibility, and whether we combine it with air sealing or insulation upgrades.
How we do it
We staple perforated radiant barrier foil across the bottom of roof rafters or lay it over existing attic insulation, ensuring proper ventilation gaps and no interference with soffit airflow.
Radiant Barrier Roof Deck
Signs you need it
New roof installation planned, or existing roof deck accessible from inside the attic with visible heat radiating through plywood.
What it costs in Schertz
Radiant barrier roof deck application in Schertz typically runs $2,000-$4,500, higher when combined with spray foam or during a roof replacement project.
How we do it
We apply radiant barrier paint or foil directly to the roof deck surface, creating a reflective layer that blocks up to 97% of radiant heat before it enters the attic cavity.
What Radiant Barrier Installation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Attic radiant barrier (foil) | $1,500 - $3,200 |
| Radiant barrier roof deck | $2,000 - $4,500 |
| Radiant barrier with air sealing package | $2,800 - $5,500 |
Does radiant barrier work with existing insulation?
Yes. Radiant barrier complements rather than replaces insulation; we often install it over settled fiberglass in Schertz attics, then top off with new blown material to reach R-38.
How much can radiant barrier lower my Schertz electric bill?
Most Schertz homeowners see 5-15% summer cooling reduction, with the biggest gains in homes with ductwork in the attic. Call (830) 402-5240 for a free estimate with projected savings.
Insulation Removal & Replacement in Schertz

Schertz’s military-family turnover means many homes have attic insulation that has been compromised by years of undetected rodent activity, water intrusion from roof leaks, or simple compression and settling of original blown fiberglass. In Belmont Park and Ashley Place, we regularly find 15-year-old insulation performing at half its original R-value. Insulation Removal & Replacement starts with safe extraction and ends with a clean, sealed, properly insulated attic.
Contaminated Insulation Removal
Signs you need it
Visible rodent droppings, urine staining, mold growth, or a persistent musty smell that worsens when the HVAC runs.
What it costs in Schertz
Contaminated insulation removal in Schertz typically runs $1,800-$3,500 depending on attic size, contamination level, and required PPE and disposal protocols.
How we do it
We set up negative air pressure containment, remove contaminated material with HEPA-filtered vacuums, bag and dispose per Texas regulations, then sanitize all surfaces before new insulation goes in.
Insulation Replacement
Signs you need it
Insulation compressed below joist tops, uneven coverage with bare spots, or energy bills that have climbed 30% or more in two years.
What it costs in Schertz
Insulation replacement in Schertz typically runs $2,200-$4,800 for standard attic jobs, with prices varying by material choice and whether air sealing is included.
How we do it
We remove old material, photograph the bare attic deck, seal all air leaks with foam and caulk, then install new blown fiberglass or cellulose to specified depth with depth markers for verification.
What Insulation Removal & Replacement Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Contaminated insulation removal | $1,800 - $3,500 |
| Standard insulation replacement | $2,200 - $4,800 |
| Removal + replacement + air sealing | $3,500 - $6,500 |
Is it safe to live in the house during insulation removal?
Yes, with proper containment. We seal attic hatches and use negative air pressure to prevent dust migration; most Schertz homeowners stay home during the work.
How do I know if my insulation is contaminated?
Dark staining, compressed tunnels, droppings, or a sharp ammonia smell indicate contamination. We inspect and photograph everything before quoting removal.
Attic Air Sealing in Schertz

Schertz’s production-built homes were framed quickly and insulated to pass inspection, not to perform. Top plates, electrical penetrations, can lights, and duct boots were rarely sealed, creating a direct path for 140°F attic air to enter conditioned space through the stack effect. Attic Air Sealing is the prerequisite step we never skip; we seal first, then insulate, and we prove the result with before-and-after blower-door numbers.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling edges, rooms that are hard to keep cool despite good insulation, or visible gaps where walls meet the ceiling in the attic.
What it costs in Schertz
Top plate and penetration sealing in Schertz typically runs $800-$1,800 as a standalone service, or is included in full attic insulation packages.
How we do it
We access the attic, identify every top plate joint, wire penetration, and plumbing stack, then seal with fire-rated foam, caulk, or rigid blocking as code requires.
Can Light & Duct Boot Sealing
Signs you need it
Hot air pouring from recessed can lights in summer, or rooms that never reach set temperature despite adequate duct sizing.
What it costs in Schertz
Can light and duct boot sealing in Schertz typically runs $400-$1,200 depending on fixture count and whether we install fire-rated covers or sealed replacement boots.
How we do it
We install pre-fabricated fire-rated enclosures over non-IC can lights, seal duct boots with mastic and mesh, and verify with smoke pencil testing before we close the attic.
What Attic Air Sealing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Top plate & penetration sealing | $800 - $1,800 |
| Can light & duct boot sealing | $400 - $1,200 |
| Full attic air sealing package | $1,500 - $3,000 |
What is a blower-door test and why does it matter?
A blower-door test is a pressurization reading that shows, in one number, how much air your building envelope is losing. We run it before and after sealing so you see the actual CFM50 reduction you paid for.
Can air sealing alone lower my bill?
Yes. In Schertz’s leaky production homes, air sealing alone often reduces cooling load 10-20% before any insulation is added. We document the change with blower-door readings.
Wall Insulation in Schertz

Schertz’s wood-frame tract homes were built with empty 2×4 exterior walls or minimal R-13 fiberglass batts that have settled or been compromised by moisture. Because these homes are slab-on-grade with no basement, walls represent the second-largest surface area for heat transfer after the attic. Wall Insulation retrofits are most common in homes where owners have already addressed attic deficiencies and still need better comfort.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that are hot to the touch in summer, cold in winter, or rooms with two exterior walls that are consistently uncomfortable.
What it costs in Schertz
Injection foam wall insulation in Schertz typically runs $3,500-$7,500 for a full home, depending on wall square footage, siding type, and cavity condition.
How we do it
We drill 2-inch holes through exterior siding or interior drywall at stud intervals, inject slow-rise foam that fills the cavity without bowing walls, then patch and match the finish.
Drill & Fill Wall Insulation
Signs you need it
Empty wall cavities confirmed by thermal imaging, or original R-13 batts that have fallen down inside the wall leaving bare drywall.
What it costs in Schertz
Drill and fill with dense-pack cellulose in Schertz typically runs $2,800-$5,500 for standard single-story homes, with two-story homes at the higher end.
How we do it
We remove a row of siding or drill interior drywall, blow cellulose to 3.5 pounds per cubic foot density for no-settle performance, then patch with matching materials.
What Wall Insulation Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Drill & fill (cellulose) | $2,800 - $5,500 |
| Injection foam (full home) | $3,500 - $7,500 |
| Exterior wall insulation with siding removal | $5,000 - $10,000 |
Will injection foam damage my walls?
No. We use slow-rise formulations and controlled pressure; in 9,000+ jobs since 2016, we have not had a wall-bowing incident. The 365-Day Done Right Promise covers any settlement or shrinkage.
Can you insulate walls without removing drywall?
Yes. Exterior access through vinyl or wood siding is standard in Schertz; we remove a row, drill, fill, and replace with matched materials.
Attic Cleaning & Rodent Proofing in Schertz

Schertz’s mature oak canopy and proximity to greenbelts along Cibolo Creek create ideal conditions for roof rats and squirrels, which enter through construction gaps in eaves and soffits common to 2000s production framing. Military turnover means infestations often go untreated for years, leaving attics in Fairhaven and Belmont Park with compacted, contaminated insulation and active entry points. Attic Cleaning & Rodent Proofing removes the evidence and stops re-entry.
Attic Sanitizing & Decontamination
Signs you need it
Visible droppings, urine stains on insulation or joists, strong ammonia odor, or HVAC filters that clog with unusual debris.
What it costs in Schertz
Attic sanitizing and decontamination in Schertz typically runs $1,500-$3,000 depending on contamination extent, attic size, and whether insulation removal is required first.
How we do it
We remove contaminated material, apply enzymatic cleaner to break down organic waste, fog with hospital-grade sanitizer, and run HEPA air scrubbers until clearance testing passes.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in walls or ceiling, droppings in the attic, or visible chew marks around soffit vents, pipe penetrations, or roof junctions.
What it costs in Schertz
Rodent proofing and exclusion in Schertz typically runs $800-$2,200 for standard homes, with complex rooflines or multiple entry points at the higher end.
How we do it
We inspect every potential entry with ladders and cameras, seal gaps with steel mesh and concrete, install chew-proof vent covers, and provide a written warranty on exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Rodent proofing & exclusion | $800 - $2,200 |
| Attic sanitizing & decontamination | $1,500 - $3,000 |
| Full attic restoration (cleanout + sanitize + re-insulate) | $3,500 - $7,000 |
How do I know if rodents are in my attic now?
Listen for scratching at dawn or dusk, check for droppings near attic hatches, and look for chew marks on fascia boards. We inspect for active entry with cameras during our estimate.
Will rodents return after you seal the attic?
Not through the same openings. Our exclusion work carries a written warranty, and we photograph every sealed point for your record. New chew attempts at other locations are rare but possible.
Home Energy Audit in Schertz

Schertz’s high military turnover and production-builder heritage mean most homes have never had a professional energy assessment. Homeowners discover problems only when bills spike or comfort fails, by which time insulation may be degraded and air leaks entrenched. Home Energy Audit provides a documented baseline: blower-door test, thermal imaging, and a written priority list with prices for every recommended fix.
Blower Door Test
Signs you need it
You suspect your home is leaky but don’t know where, or you’ve completed insulation work and want to verify the result with a hard number.
What it costs in Schertz
A standalone blower-door test in Schertz typically runs $250-$450, or is included in our full home energy audit package.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50, then walk the house with a smoke pencil to locate every significant leak path.
Thermal Imaging Inspection
Signs you need it
Uneven temperatures between rooms, suspected missing insulation in walls, or moisture intrusion that standard inspection cannot locate.
What it costs in Schertz
Thermal imaging inspection in Schertz typically runs $300-$500 as a standalone service, or bundled with blower-door testing and full audit.
How we do it
We scan every interior and exterior surface with a FLIR camera during controlled conditions, marking thermal bridges, insulation gaps, and moisture patterns directly on the images you receive.
What Home Energy Audit Costs in Schertz
| Item | Typical range in Schertz |
|---|---|
| Blower-door test (standalone) | $250 - $450 |
| Thermal imaging inspection | $300 - $500 |
| Full home energy audit | $400 - $750 |
What does a full home energy audit include?
Blower-door test, thermal imaging, insulation inspection, duct leakage test, and a written report with prioritized recommendations and exact prices. You leave with documentation, not a sales pitch.
Should I get an audit before or after buying a Schertz home?
Before closing if possible. Many Schertz homes have hidden air leaks and settled insulation; an audit gives you leverage for repairs or price adjustment. Call (830) 402-5240 to schedule.
