Why Windcrest Homes Are Different
Windcrest was incorporated in 1953 and built out rapidly as a planned residential enclave through the 1960s and early 1970s. That leaves us with a remarkably uniform stock of mid-century ranch homes where virtually every attic was insulated, if at all, to the minimal standards of that era. Unlike neighboring San Antonio’s patchwork of construction eras, an insulation contractor in Windcrest deals with the same vintage, the same deficiencies, and the same retrofit opportunity across nearly the entire city.
The dominant housing type is single-story, slab-on-grade ranch construction with low-pitched roofs and shallow attic cavities. Original blown fiberglass has settled to R-11 or lower, and wall cavities were almost always left empty, both common shortcuts in Bexar County residential construction of that period. Because these homes are almost universally slab-foundation ranch builds with ductwork routed through unconditioned attics, we consistently find original or early-replacement flex duct with only 1-inch duct wrap, a compounding loss point where poorly insulated ducts run through a poorly insulated attic. Summer cooling dominates the energy bill here, so attic air sealing and bringing insulation to current IECC R-38 or higher standards delivers the most measurable return.
Our Main Windcrest Services
Windcrest homeowners call us most often about attic upgrades and spray foam retrofits. Here is what those jobs look like in this market.
Attic Insulation in Windcrest
We start every Attic Insulation in Windcrest job with a blower-door test to establish the baseline air leakage rate, then seal top plates, can lights, and duct boots before adding any new material. In Windcrest’s shallow attic cavities, we often use Owens Corning blown fiberglass or GreenFiber cellulose to hit R-38 without compressing against the roof deck. The documented photo record includes before-and-after blower-door numbers so you can verify the air-sealing result.
Spray Foam Insulation in Windcrest
Spray Foam Insulation in Windcrest works best for enclosed attics, rim joists, and the occasional second-story addition where conventional insulation cannot achieve full contact. We use open-cell Icynene or closed-cell Demilec products depending on the assembly and moisture risk. Every job gets a written scope, written price, and written warranty before anyone lifts a tool, per Haven Standard Clause 1.
Blown-In Insulation in Windcrest
Blown-In Insulation in Windcrest is the most common retrofit for ranch homes with accessible attics and settled original material. We remove or work around the old layer, air seal the attic floor, then blow new fiberglass or cellulose to uniform depth with marked rulers visible from the hatch. The 365-Day Done Right Promise covers all completed work.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Windcrest
Windcrest’s slab-on-grade ranch dominance means true crawl spaces are uncommon here, but where they do exist, typically in additions or split-level conversions from the 1970s, they suffer from the same Gulf Coast humidity that affects the rest of Bexar County. A sealed crawl space in this climate prevents the mold, rot, and indoor air quality problems that start when warm, moist outside air meets cooler foundation surfaces. Crawl Space Encapsulation & Vapor Barrier is not a standard need for every Windcrest home, but where a crawl exists, it is usually the most urgent building-envelope repair.
Crawl Space Vapor Barrier
Signs you need it
You notice musty odors, visible mold on floor joists, or standing water after rain.
What it costs in Windcrest
A 6-mil to 20-mil vapor barrier installation in Windcrest typically runs $1,200-$2,800 for a small to medium crawl footprint.
How we do it
We clear debris, grade the soil, seam-seal the polyethylene sheeting, and mechanically fasten it to foundation walls.
Crawl Space Encapsulation
Signs you need it
Your crawl has chronic humidity above 70 percent, insect activity, or fiberglass insulation falling from the joists.
What it costs in Windcrest
Full encapsulation with sealed vents, dehumidifier, and insulated walls in Windcrest generally falls between $3,500 and $7,500.
How we do it
We install rigid foam board on walls, seal all vents and penetrations, lay overlapped vapor barrier, and size a dedicated dehumidifier.
What Crawl Space Encapsulation & Vapor Barrier Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Vapor barrier only (6-20 mil) | $1,200 - $2,800 |
| Partial encapsulation (walls or floor) | $2,500 - $5,000 |
| Full encapsulation with dehumidifier | $3,500 - $7,500 |
How long does crawl space encapsulation take in Windcrest?
Most jobs finish in two to three days, with one day for prep and barrier work and another for sealing and dehumidifier setup. Call (830) 549-6646 for an exact quote, estimates are free.
Will encapsulation help with indoor air quality?
Yes, sealing the crawl blocks the stack effect that pulls mold spores and soil gases into living spaces. We document the before-and-after humidity readings in your photo record.
Radiant Barrier Installation in Windcrest
Windcrest attic temperatures regularly exceed 150°F in summer, and the original 1960s-1970s ranch homes here have low-pitched roofs with minimal ventilation paths. A radiant barrier reflects solar gain rather than absorbing it, reducing the radiant heat transfer that makes ductwork in the attic work against itself. Radiant Barrier Installation is one of the most cost-effective cooling-load reductions available for this housing stock, especially when paired with proper air sealing and insulation upgrades.
Attic Radiant Barrier
Signs you need it
Your second-story rooms or duct-fed spaces run 8-12°F warmer than the thermostat setting in afternoon peak sun.
What it costs in Windcrest
Radiant barrier installation in a typical Windcrest ranch attic runs $1,500-$3,200 depending on access difficulty and square footage.
How we do it
We staple perforated foil across rafter bays or lay it over existing insulation, ensuring ventilation channels remain open.
Radiant Barrier Roof Deck
Signs you need it
You are reroofing or have decking exposed during repairs and want permanent radiant reflectance at the source.
What it costs in Windcrest
Deck-applied radiant barrier during reroofing or retrofit in Windcrest typically costs $2,000-$4,500.
How we do it
We apply foil-faced sheathing or liquid-applied low-emissivity coating directly to the roof deck before shingle or metal installation.
What Radiant Barrier Installation Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Attic radiant barrier (foil over insulation) | $1,500 - $3,200 |
| Radiant barrier roof deck application | $2,000 - $4,500 |
| Radiant barrier with attic air sealing package | $2,800 - $5,500 |
Does radiant barrier work with existing insulation?
Yes, it complements insulation by addressing radiant heat, the dominant cooling load in Windcrest attics. Call (830) 549-6646 for a free estimate with written price before any work starts.
Will radiant barrier affect my cell signal or Wi-Fi?
Perforated foil barriers have negligible effect; solid foil in full contact with decking can attenuate signals slightly, which we discuss during scope review.
Insulation Removal & Replacement in Windcrest
Windcrest’s uniform stock of 1960s-1970s ranch homes means we encounter the same degraded materials repeatedly: settled blown fiberglass compressed to R-11 or lower, rodent-contaminated batts, and occasional vermiculite in homes built before 1980. Insulation Removal & Replacement is often the first step before air sealing and new insulation can perform as designed, and we never add new material over compromised old layers.
Attic Insulation Removal
Signs you need it
Your attic insulation is visibly compressed, water-stained, or emits a urine or mildew odor when the hatch is opened.
What it costs in Windcrest
Attic insulation removal in a typical Windcrest ranch runs $1,000-$2,500 depending on volume and accessibility.
How we do it
We use commercial vacuums with HEPA filtration, bag the material on-site, and dispose per Bexar County regulations.
Contaminated Insulation Removal
Signs you need it
You have found rodent droppings, nesting material, or mold growth extending through more than 10 percent of the attic area.
What it costs in Windcrest
Contaminated removal with PPE, sanitizing, and deodorizing in Windcrest typically costs $2,000-$4,500.
How we do it
We suit up, remove contaminated material, apply enzyme treatment to substrates, and verify with post-removal photo documentation.
What Insulation Removal & Replacement Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Standard attic insulation removal | $1,000 - $2,500 |
| Contaminated insulation removal | $2,000 - $4,500 |
| Removal plus replacement to R-38 | $3,500 - $7,000 |
Can you remove insulation with asbestos or vermiculite?
We test suspect material before disturbing it; if asbestos is present, we coordinate with licensed abatement contractors. Call (830) 549-6646 for testing and a free written plan.
How long does removal and replacement take?
Most Windcrest ranch attics take one day for removal and another for air sealing and new insulation, with the house fully serviceable each evening.
Attic Air Sealing in Windcrest
Windcrest’s 1960s-1970s ranch homes were built before blower-door testing was standard, and the construction practices of that era left pervasive leakage paths: top plates, electrical penetrations, can lights, and attic hatches. In a climate where summer attic temperatures exceed 150°F, every cubic foot of conditioned air that escapes into the attic is replaced by hot, humid outdoor air that your AC must then dehumidify and cool. Attic Air Sealing is the hard prerequisite we complete before any insulation goes in, and we publish before-and-after blower-door numbers on every job so you can see the performance change.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage at the attic floor, or you feel drafts at outlets and switches on exterior walls.
What it costs in Windcrest
Top plate and penetration sealing in a typical Windcrest ranch attic runs $800-$1,800.
How we do it
We foam-seal all wall top plates, wire and pipe penetrations, and chase openings with two-component polyurethane or acoustical sealant.
Can Light & Duct Boot Sealing
Signs you need it
You have unsealed can lights or flexible duct boots that leak visible dust or feel hot to the touch in summer.
What it costs in Windcrest
Can light and duct boot sealing in Windcrest typically costs $400-$1,200 depending on fixture count and duct configuration.
How we do it
We install fire-rated covers over can lights, mastic-seal duct boots, 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 | $800 - $1,800 |
| Can light and duct boot sealing | $400 - $1,200 |
| Full attic air sealing package | $1,500 - $3,500 |
Do I need air sealing if I already have insulation?
Yes, insulation does not stop air movement; we regularly find R-19 batts performing like R-11 because wind washing pulls heat right through. Call (830) 549-6646 for a blower-door test and free written estimate.
What blower-door number should a Windcrest ranch home hit?
We target 1,500-2,500 CFM50 for a 1,200-1,800 square foot ranch after sealing, down from typical pre-work readings of 4,000-6,000 CFM50.
Wall Insulation in Windcrest
Windcrest’s mid-century ranch homes were almost universally built with empty wall cavities, a Bexar County shortcut that saves the builder pennies and costs the homeowner for decades. In a cooling-dominated climate where outdoor temperatures reach 105°F, uninsulated walls act as radiators that reverse their heat flow from afternoon sun exposure straight into living spaces. Wall Insulation retrofit is one of the most impactful upgrades available for this housing stock, and we have multiple methods depending on your siding type and interior finish.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in afternoon sun, or rooms with west exposure stay uncomfortably warm despite adequate attic insulation.
What it costs in Windcrest
Drill-and-fill cellulose or fiberglass in a typical Windcrest ranch runs $2,500-$5,500 depending on wall area and exterior finish.
How we do it
We drill 2-inch holes at stud bay intervals, blow insulation to verified density, and plug with matched siding or interior patch.
Injection Foam Wall Insulation
Signs you need it
You want higher R-value per inch and air-sealing benefit in a single step, or your walls have obstructions that prevent uniform loose-fill.
What it costs in Windcrest
Injection foam wall insulation in Windcrest typically costs $4,000-$8,500 for a full ranch home.
How we do it
We inject slow-rise open-cell foam through similar access points, controlling expansion to avoid bowing studs or drywall.
What Wall Insulation Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Drill-and-fill cellulose or fiberglass | $2,500 - $5,500 |
| Injection foam wall insulation | $4,000 - $8,500 |
| Exterior wall insulation with siding removal | $6,000 - $12,000 |
Will drill-and-fill damage my siding or drywall?
We match plugs to existing material and texture; on painted hardboard or brick, holes are drilled in mortar joints or concealed courses. Call (830) 549-6646 for a free scope review with written price.
How much does wall insulation save on cooling bills?
Most Windcrest homeowners see 15-25 percent cooling reduction when empty walls are filled, especially on west and south exposures.
Attic Cleaning & Rodent Proofing in Windcrest
Windcrest’s mature tree canopy and established neighborhoods create ideal rodent highway systems, and the shallow attic cavities of 1960s-1970s ranch homes offer warm, undisturbed nesting sites. Once rodents have accessed an attic, compressed fiberglass becomes nesting material, droppings contaminate the air seal plane, and pheromone trails attract successive populations. Attic Cleaning & Rodent Proofing is often the necessary first step before any insulation work can proceed with a clean substrate.
Attic Cleanout
Signs you need it
Your attic contains stored debris, old insulation fragments, or rodent nesting material that prevents proper air sealing and insulation contact.
What it costs in Windcrest
Attic cleanout in a typical Windcrest ranch runs $500-$1,500 depending on volume and hazard level.
How we do it
We remove all debris and compromised material, HEPA-vacuum surfaces, and document the clean substrate with photos before next steps.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find droppings near the attic hatch, or see gnaw marks on fascia or soffit vents.
What it costs in Windcrest
Rodent proofing and exclusion for a Windcrest ranch typically costs $800-$2,000 including entry-point sealing and one-way doors.
How we do it
We identify all entry points with photo documentation, seal with rodent-proof materials, install one-way exits, and verify with follow-up inspection.
What Attic Cleaning & Rodent Proofing Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Attic cleanout only | $500 - $1,500 |
| Rodent proofing and exclusion | $800 - $2,000 |
| Cleanout, proofing, and insulation replacement | $3,000 - $6,500 |
How do I know rodents are gone before you reinsulate?
We set one-way doors at primary entries and return to verify no new activity before installing new insulation; this is documented in your photo record. Call (830) 549-6646 to schedule inspection.
Does rodent proofing include trapping inside the attic?
We coordinate with wildlife specialists for live trapping when needed; our scope is structural exclusion and substrate preparation for insulation work.
Home Energy Audit in Windcrest
A Windcrest ranch home built in 1965 and one built in 1972 often perform identically poorly, but the specific leakage paths and retrofit priorities differ based on additions, roofing history, and duct configuration. A Home Energy Audit gives you a ranked list of improvements with predicted savings, so you can decide whether to attack the attic first, the walls, or the duct system. We dispatch from our San Antonio office and serve Windcrest with local crews who know this housing stock.
Blower Door Test
Signs you need it
You want a single number that quantifies your home’s total air leakage, or you are comparing quotes and need an objective baseline.
What it costs in Windcrest
A standalone blower-door test in Windcrest runs $250-$450; it is included free with any proposal for work.
How we do it
We install a calibrated fan in an exterior door, depressurize to 50 Pascals, and measure CFM50 with infrared imaging to locate leakage paths.
Thermal Imaging Inspection
Signs you need it
You have uneven temperatures between rooms, suspect missing insulation, or want to verify contractor work from a previous job.
What it costs in Windcrest
Thermal imaging inspection in Windcrest typically costs $200-$400 as a standalone service, or bundled with the full audit.
How we do it
We scan walls, ceilings, and ductwork with a FLIR camera during normal heating or cooling operation, marking thermal bridges and gaps for the report.
What Home Energy Audit Costs in Windcrest
| Item | Typical range in Windcrest |
|---|---|
| Blower-door test (standalone) | $250 - $450 |
| Thermal imaging inspection | $200 - $400 |
