Insulation in Windcrest, TX
Crawl space encapsulation and vapor barrier work in Windcrest runs $2,800-$6,500 for most ranch homes, with full encapsulations typically completed in two days. Nearly every home here was built between 1953 and the mid-1970s on slab-on-grade foundations, so true crawl spaces are limited - but where they exist, the original vapor barriers have long since degraded, and the clay soils common to this pocket of Bexar County wick moisture upward year-round. We start every job with a written price and a documented photo record, and our crews serve Windcrest from our San Antonio office. Call (830) 243-6352 for a free estimate.
Why Windcrest Homes Are Different
Windcrest is a small incorporated enclave built almost entirely in a single 20-year span, creating an unusually uniform pocket of mid-century ranch homes where virtually every structure predates modern energy codes. Unlike the surrounding San Antonio metro, where housing spans multiple eras, Windcrest homeowners face one consistent problem: original attic insulation that has settled and degraded through 50-plus summers with attic temperatures routinely exceeding 150°F.
The low-pitched rooflines characteristic of this era create shallow, tight attic cavities that complicate access and thorough coverage. In January, the February 2021 Winter Storm Uri exposed how little cold protection these homes have, accelerating demand for full-envelope assessments. And each December, Windcrest’s famous citywide Christmas lights tradition leads homeowners to run new electrical circuits through attic spaces, displacing and compressing existing batt insulation - a pattern we account for in first-quarter service calls.
Our Main Windcrest Services
Windcrest homeowners call us most often for attic work and spray foam - here is what those jobs involve locally.
Attic Insulation in Windcrest
Attic retrofits in Windcrest mean working in shallow cavities under low-pitched roofs, removing compressed original batts, sealing top plates and can lights, then installing new insulation to R-38 or R-49. We publish before-and-after blower-door numbers on every job so you can verify the air-sealing result. Attic Insulation in Windcrest covers the full process, materials from Owens Corning and Johns Manville, and what the written scope includes.
Spray Foam Insulation in Windcrest
Spray foam works exceptionally well in Windcrest’s tight attic spaces where batts are hard to fit properly. We use open-cell foam for attic floors and rafter bays, closed-cell for rim joists and crawl spaces, sourced from Demilec and Icynene. Every job starts with air sealing, never after. Spray Foam Insulation in Windcrest details pricing, coverage, and the Haven Standard documentation you receive.
Blown-In Insulation in Windcrest
Blown-in cellulose from GreenFiber or fiberglass from Knauf is our most common retrofit for Windcrest ranch homes with accessible attics. We install only after air sealing is complete - blowing insulation over an unsealed attic floor traps conditioned air leaks beneath the new layer. Blown-In Insulation in Windcrest explains density, coverage rates, and the written price guarantee.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Windcrest
True crawl spaces are uncommon in Windcrest’s slab-on-grade ranch stock, but where they exist - typically in additions, converted garages, or homes on the area’s few elevated lots - the original 6-mil polyethylene vapor barriers installed in the 1960s and 70s have degraded to the point of uselessness. The clay-heavy soils here hold moisture through every season, and without a functioning vapor barrier, that moisture rises into floor framing, insulation, and living spaces. Crawl Space Encapsulation & Vapor Barrier is the starting point for homeowners who need full moisture control.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, visible mold on floor joists, or a musty smell that enters the living space through gaps in the subfloor.
What it costs in Windcrest
A new vapor barrier installation in Windcrest typically runs $1,200-$2,800 depending on square footage and whether the old material requires removal.
How we do it
We remove degraded existing poly, grade the soil surface, lay 10-20 mil reinforced polyethylene with sealed seams, and extend it 6-12 inches up foundation walls.
Crawl Space Encapsulation
Signs you need it
You’re running a dehumidifier constantly, seeing rust on ductwork, or finding insulation falling from floor joists due to moisture weight.
What it costs in Windcrest
Full encapsulation with sealed walls, conditioned air supply, and dehumidification in Windcrest ranges from $4,500-$8,500 for typical residential crawl spaces.
How we do it
We install reinforced liner on floors and walls, seal all seams and penetrations, add mechanical dehumidification, and provide before-and-after moisture readings.
What Crawl Space Encapsulation & Vapor Barrier Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Vapor barrier replacement | $1,200 - $2,800 |
| Partial encapsulation (walls or floor only) | $2,800 - $4,500 |
| Full encapsulation with dehumidification | $4,500 - $8,500 |
How long does crawl space work take in Windcrest?
Most vapor barrier replacements finish in one day; full encapsulations with mechanical dehumidification typically require two days. We schedule around your availability and provide a named technician with text notifications.
Can you encapsulate a crawl space with active plumbing leaks?
No - we require plumbing repairs first, then return to encapsulate. Trapping moisture against sealed walls accelerates decay; we document the condition with photos and note needed repairs in your written scope.
Radiant Barrier Installation in Windcrest
Radiant heat gain dominates Windcrest’s energy profile - an 8-month cooling season and attic temperatures past 150°F mean your roof deck is essentially a radiator pointed at your living space. The original mid-century ranch homes here were built with no radiant barrier at all, and even homes with later attic upgrades rarely have proper roof-deck coverage. Installing radiant barrier - reflective foil or coated roof decking that blocks infrared heat transfer - is the single most cost-effective upgrade for cooling-dominated homes in Climate Zone 2. Radiant Barrier Installation details the full product line and performance documentation.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 PM, your AC runs continuously on sunny afternoons, or your ductwork in the attic feels hot to the touch.
What it costs in Windcrest
Attic radiant barrier installation in Windcrest typically costs $1,800-$3,500 for a standard ranch home, depending on attic square footage and accessibility.
How we do it
We staple perforated foil across rafter bottoms or lay it over existing insulation, maintaining ventilation channels and documenting coverage with photos.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the most effective radiant barrier integration, or your existing shingles are failing and the deck is exposed.
What it costs in Windcrest
Radiant barrier roof deck installation during re-roofing in Windcrest adds $2,200-$4,000 to the roofing project for typical ranch footprints.
How we do it
We install foil-faced OSB or apply reflective coating directly to the roof deck before shingle installation, coordinating with your roofing contractor.
What Radiant Barrier Installation Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Attic radiant barrier (foil over insulation) | $1,800 - $3,500 |
| Radiant barrier roof deck (during re-roof) | $2,200 - $4,000 |
| Radiant barrier with attic air sealing package | $3,200 - $5,500 |
Does radiant barrier work with existing insulation?
Yes - radiant barrier complements rather than replaces insulation, reducing radiant heat gain so your existing R-value performs better. We assess current insulation depth and condition before recommending the combination.
Will radiant barrier help in winter?
Radiant barrier primarily reduces cooling loads; in Windcrest’s mild winters, the benefit is minimal. We pair it with proper attic insulation for year-round performance and document the seasonal impact in your written scope.
Insulation Removal & Replacement in Windcrest
Windcrest’s uniform housing stock means we remove the same materials repeatedly: compressed original fiberglass batts from 1953-1975, early blown-in that has settled to half its labeled R-value, and insulation contaminated by decades of roof leaks or rodent activity. The shallow attic cavities complicate removal - there’s little room to maneuver vacuum hoses or bag out debris. We never install new insulation over old without assessing what’s beneath; hidden moisture or pest damage trapped under a new layer creates worse problems. Insulation Removal & Replacement covers the full assessment and documentation process.
Attic Insulation Removal
Signs you need it
Your insulation is compressed below the joist tops, you can see the ceiling drywall through gaps, or you’ve had roof leaks that soaked the material.
What it costs in Windcrest
Attic insulation removal in Windcrest runs $1,500-$3,000 for a standard ranch home, with tight cavities or extensive debris adding to labor time.
How we do it
We use commercial vacuums with HEPA filtration, bag debris at the attic hatch, and photo-document the bare deck before any new material goes in.
Contaminated Insulation Removal
Signs you need it
You smell urine or decay in the attic, see rodent droppings mixed with insulation, or have found dead pests during prior HVAC service.
What it costs in Windcrest
Contaminated insulation removal with sanitizing in Windcrest typically costs $2,500-$4,500 depending on contamination extent and whether rodent proofing is needed.
How we do it
We remove all affected material, apply enzymatic sanitizer to exposed surfaces, install new insulation only after verification, and provide photo documentation.
What Insulation Removal & Replacement Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Standard attic insulation removal | $1,500 - $3,000 |
| Contaminated insulation removal with sanitizing | $2,500 - $4,500 |
| Removal plus replacement to R-38/R-49 | $4,000 - $7,500 |
Do I have to leave during insulation removal?
No - our vacuums exhaust outside and we seal the attic hatch during work. We notify you when the removal phase is complete and provide photos before replacement begins.
Can you remove vermiculite insulation?
We do not handle vermiculite - it may contain asbestos and requires specialized abatement contractors. We can identify it during assessment and refer you to certified remediators; we return for replacement after clearance.
Attic Air Sealing in Windcrest
Air sealing is the hard prerequisite we never skip - and in Windcrest’s mid-century ranch homes, the leakage paths are remarkably consistent. Top plates where walls meet the attic floor are rarely sealed, can lights from the 1960s and 70s are essentially open chimneys to the attic, and duct boots pull conditioned air directly into unconditioned space. We perform blower-door testing before and after sealing so you can see the performance change in a single number - CFM50, the cubic feet per minute of air leakage at 50 pascals of pressure. Attic Air Sealing explains the full protocol and what the documentation includes.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from outlets on exterior walls, see dust streaks around ceiling fixtures, or your blower-door test shows excessive leakage for your home’s size.
What it costs in Windcrest
Top plate and penetration sealing in Windcrest typically runs $1,200-$2,500 for a standard ranch, with extensive wiring or plumbing penetrations adding labor.
How we do it
We access top plates from the attic, apply fire-rated caulk and foam at all joints, seal around every wire and pipe penetration, and verify with blower-door comparison.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in high winds, rooms farthest from the HVAC unit are consistently hotter or colder, or you see conditioned air escaping around ceiling registers.
What it costs in Windcrest
Can light and duct boot sealing in Windcrest costs $800-$1,800 depending on fixture count and whether boots require reconstruction or just sealing.
How we do it
We install fire-rated covers over can lights, seal with mastic at duct boot connections, and pressure-test the duct system where accessible.
What Attic Air Sealing Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Top plate and penetration sealing | $1,200 - $2,500 |
| Can light and duct boot sealing | $800 - $1,800 |
| Full attic air sealing with blower-door test | $2,200 - $4,200 |
Can air sealing be done without adding insulation?
Yes - we perform standalone air sealing with blower-door verification. Many Windcrest homeowners stage the work: seal first, verify the reduction, then add insulation in a subsequent season.
How much does blower-door testing reduce leakage?
Typical Windcrest ranch homes start at 3,500-5,500 CFM50 and finish at 2,000-3,500 CFM50 after comprehensive attic sealing. We publish both numbers in your written record.
Wall Insulation in Windcrest
Windcrest’s mid-century ranch homes were built with 2×4 exterior walls and minimal or no cavity insulation - R-7 or R-11 batts where you’re lucky, empty cavities where you’re not. The slab-on-grade construction means there’s no basement rim joist to address, so wall performance dominates the thermal envelope after the attic is handled. Retrofitting wall insulation in these homes requires drilling access holes or removing interior drywall, which we plan carefully to minimize disruption. Wall Insulation covers methods, materials, and the written scope process.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, you have no insulation at outlets when checked, or your home was built before 1975 with original siding intact.
What it costs in Windcrest
Drill-and-fill wall insulation in Windcrest runs $2,500-$5,000 for a standard ranch home, with stucco or brick exteriors requiring more labor than siding.
How we do it
We drill 2-inch holes at stud bay intervals, blow dense-pack cellulose or fiberglass to verified density, plug with matching material, and photo-document each bay.
Injection Foam Wall Insulation
Signs you need it
You need higher R-value in limited cavity depth, have irregular stud spacing that complicates blown-in, or want air sealing along with insulation in one step.
What it costs in Windcrest
Injection foam wall insulation in Windcrest typically costs $3,500-$6,500 for a standard ranch, with open-cell or closed-cell options depending on moisture management needs.
How we do it
We access cavities through exterior or interior holes, inject slow-rise foam to fill completely, trim excess after cure, and seal all access points.
What Wall Insulation Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Drill-and-fill (cellulose or fiberglass) | $2,500 - $5,000 |
| Injection foam (open-cell) | $3,500 - $6,500 |
| Injection foam (closed-cell) | $5,000 - $9,000 |
Will wall insulation require replacing my siding?
Rarely - we drill through siding and patch; stucco requires more extensive repair. We assess your exterior during the initial visit and note the access plan in your written price.
How much does wall insulation improve comfort?
Wall insulation in Windcrest’s uninsulated 2×4 walls typically reduces conductive heat gain by 60-70% and eliminates the hot-wall effect. We measure with thermal imaging before and after to verify.
Attic Cleaning & Rodent Proofing in Windcrest
Windcrest’s mature tree canopy and established neighborhoods create ideal rodent habitat, and the shallow, warm attic cavities in these mid-century homes are prime nesting territory. December Christmas light installations disturb existing insulation, creating gaps and compression points that rodents exploit. We find droppings, nesting material, and damaged insulation in roughly half the Windcrest attics we assess - and we never install new insulation over contamination. Attic Cleaning & Rodent Proofing details the full remediation protocol.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at night, find droppings in the attic, or smell ammonia or decay when the HVAC runs.
What it costs in Windcrest
Attic cleanout with sanitizing in Windcrest runs $1,800-$3,500 depending on contamination extent, insulation volume to remove, and accessibility constraints.
How we do it
We remove all contaminated material, HEPA-vacuum surfaces, apply enzymatic sanitizer, and photo-document the sanitized deck before any restoration work.
Rodent Proofing & Exclusion
Signs you need it
You’ve had repeated rodent activity despite trapping, can see gaps at roof junctions or vent screens, or find new droppings within weeks of cleaning.
What it costs in Windcrest
Rodent proofing and exclusion in Windcrest typically costs $1,200-$2,800 for comprehensive sealing of all entry points on a standard ranch home.
How we do it
We inspect the full roofline, seal all penetrations with rodent-proof materials, install hardware cloth over vents, and guarantee the exclusion for one year.
What Attic Cleaning & Rodent Proofing Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Attic cleanout with sanitizing | $1,800 - $3,500 |
| Rodent proofing and exclusion | $1,200 - $2,800 |
| Full restoration (cleanout, proofing, re-insulation) | $4,500 - $8,500 |
Do you handle live rodent removal?
No - we partner with licensed pest control for active infestations. We begin our work after they’ve cleared the population, then prevent re-entry with permanent exclusion.
How do I know if rodents have returned?
We install monitoring indicators at common entry points and schedule follow-up inspections. Our one-year exclusion guarantee covers any necessary re-sealing at no charge.
Home Energy Audit in Windcrest
A home energy audit in Windcrest reveals what 50 years of settling, deferred maintenance, and pre-code construction have done to your thermal envelope. The blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope is losing - typically exposes 3,500-5,500 CFM50 of leakage in these ranch homes, often double what modern construction permits. We combine this with thermal imaging to locate missing insulation, duct leakage testing to quantify HVAC losses, and a written scope with prioritized recommendations. Home Energy Audit details the full protocol and documentation package.
Blower Door Test
Signs you need it
Your utility bills are rising without rate changes, rooms have persistent temperature differences, or you’re planning major insulation work and want a baseline.
What it costs in Windcrest
A standalone blower-door test in Windcrest costs $350-$550; as part of a full energy audit, it’s included in the comprehensive package price.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 pascals, measure airflow, and identify leakage paths with smoke pencils and thermal imaging.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation behind walls, need to verify recent insulation work, or want to locate air leaks the blower door confirmed but didn’t pinpoint.
What it costs in Windcrest
Thermal imaging as part of a full audit in Windcrest is included; standalone thermal inspection runs $250-$400 for a typical ranch home.
How we do it
We scan all building surfaces with a FLIR camera during controlled temperature differential, mark anomalies on photos, and include findings in your written report.
What Home Energy Audit Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Standalone blower-door test | $350 - $550 |
| Full home energy audit with thermal imaging | $450 - $750 |
| Audit with duct leakage testing | $650 - $950 |
How long does a home energy audit take?
A full audit requires 3-4 hours on site, plus preparation time for temperature differential. We schedule morning starts for best thermal imaging conditions and deliver your written report within 48 hours.
Will the audit force me to buy services?
No - the audit is diagnostic only. We provide prioritized recommendations with pricing, and you choose what to proceed with. Many Windcrest homeowners stage work over multiple seasons.

What Windcrest 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."They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R.
