Insulation in Bulverde, TX
Crawl space encapsulation and vapor barrier installation in Bulverde typically runs $3,500-$7,500 for most single-family homes, with full encapsulations on larger Hill Country properties reaching $8,500-$12,000. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in - not an upsell. In Bulverde’s production-built subdivisions, we regularly find relatively new homes with crawl spaces that trap the Hill Country’s humidity against floor joists, creating mold conditions in houses that aren’t even a decade old. Call (830) 402-5240 for a written price before any work starts.
Why Bulverde Homes Are Different
Bulverde sits on the exposed limestone ridgelines of the Edwards Plateau, where the San Antonio metro’s fastest-growing suburb meets open Hill Country terrain. The housing stock is overwhelmingly slab-on-grade and pier-and-beam single-family homes in master-planned subdivisions built from the early 2000s through the 2020s by volume production builders - D.R. Horton, Lennar, Perry, and similar - who installed blown-in fiberglass at the minimum R-value Texas energy code required at the time.
That minimum-code approach collides with Bulverde’s climate reality. IECC Climate Zone 2 brings summer highs past 100°F for weeks, and the lack of tree cover on these ridgelines pushes attic temperatures past 140°F. Winter Storm Uri in February 2021 proved how poorly those attic cavities protect pipes and HVAC equipment. In neighborhoods like Bulverde North, Johnson Ranch, and Timberwood Park, we routinely find homes under 15 years old where insulation has settled to effective R-22 or lower - well below the R-38 this climate demands - leaving owners with inexplicably high Pedernales Electric or GVEC bills in houses that look too new to have problems.
Our Main Bulverde Services
Most Bulverde homeowners who call us start with one of these three jobs.
Attic Insulation in Bulverde
Attic insulation in Bulverde means addressing the 140°F+ temperatures that bake minimum-code fiberglass into premature failure. We remove settled or compressed material, seal every top plate and penetration with the blower door running, then install to true R-38 or R-49 with Owens Corning or Johns Manville products. Every job gets before-and-after blower-door numbers so you can verify the air-sealing result. Attic Insulation in Bulverde covers our full process and pricing.

Spray Foam Insulation in Bulverde
Spray foam insulation in Bulverde makes sense for homeowners who want to solve air leakage and insulation in one pass, especially in complex rooflines or conditioned attics where fiberglass can’t perform. We use open-cell Icynene and closed-cell Demilec products, applied after dedicated air sealing of the building envelope. The Haven Standard requires a written price before any work starts, and we publish blower-door results on every applicable job. Spray Foam Insulation in Bulverde has full details.

Blown-In Insulation in Bulverde
Blown-in insulation in Bulverde is the most common retrofit we perform, typically upgrading settled builder-grade fiberglass to proper depth and density with GreenFiber cellulose or Owens Corning fiberglass. We never blow new material over an unsealed attic floor - top plates, can lights, and duct boots get sealed first while the blower door confirms the reduction in air leakage. Blown-In Insulation in Bulverde explains our full approach.

Crawl Space Encapsulation & Vapor Barrier in Bulverde

Bulverde’s Hill Country location means crawl spaces here deal with a specific moisture pattern: limestone bedrock wicks groundwater upward, and the area’s clay-loam soils hold humidity against pier-and-beam foundations that volume builders often left poorly vented. In subdivisions like Johnson Ranch and Bulverde North, we’ve found crawl spaces under 8-year-old homes with relative humidity above 80% and floor joist staining that the homeowner never saw because no one had looked. Crawl Space Encapsulation & Vapor Barrier is the full scope we deliver.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or soft spots in subflooring that feel spongy from below.
What it costs in Bulverde
A 6-mil or thicker polyethylene vapor barrier installed across the crawl floor typically runs $1,200-$2,800 in Bulverde, with larger Hill Country homes or those requiring significant grading prep reaching $3,200-$4,500.
How we do it
We remove debris and level the soil, seam-seal 10-mil reinforced polyethylene across the entire floor and 6 inches up piers, then seal all seams and penetrations with mastic tape before documenting with photos.
Crawl Space Encapsulation
Signs you need it
You smell mustiness inside the home, your hardwood floors are cupping, or your HVAC runs constantly in summer because humid crawl space air is infiltrating the envelope.
What it costs in Bulverde
Full encapsulation with sealed vapor barrier, insulated walls, and conditioned air supply typically costs $5,500-$8,500 in Bulverde, with extensive pier-and-beam homes or those requiring dehumidification systems reaching $9,500-$14,000.
How we do it
We seal all vents, install reinforced vapor barrier floor-to-wall, apply rigid foam insulation to foundation walls, add a mechanical dehumidifier with condensate pump, and verify with humidity logging for 72 hours before final walkthrough.
What Crawl Space Encapsulation & Vapor Barrier Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Vapor barrier (floor only) | $1,200 - $2,800 |
| Partial encapsulation | $3,500 - $6,500 |
| Full encapsulation with dehumidification | $5,500 - $14,000 |
How long does crawl space encapsulation take in Bulverde?
Most vapor barrier jobs finish in one day; full encapsulations with dehumidification take two to three days. We coordinate scheduling from our Dallas-Fort Worth office, with Bulverde crews arriving on confirmed appointment windows.
Will encapsulation lower my electric bill in Bulverde?
Yes - we typically see 15-25% HVAC runtime reduction after full encapsulation because the system stops fighting humid infiltration. Call (830) 402-5240 for a free estimate with written price before any work starts.
Radiant Barrier Installation in Bulverde

Bulverde’s exposed ridgelines and minimal tree cover create a specific problem: roof decking absorbs intense solar gain for months, radiating heat downward into attic insulation that’s already struggling against 140°F+ ambient temperatures. In production homes from the 2000s-2020s, builders rarely installed radiant barriers despite the obvious solar load, leaving attics as uncontrolled heat sinks that reverse-drive thermal transfer into conditioned space. Radiant Barrier Installation is how we address this.
Attic Radiant Barrier
Signs you need it
Your attic feels like a furnace by 10 a.m., your second floor won’t cool below 78°F in August, or your roof decking is too hot to touch from inside the attic.
What it costs in Bulverde
Attic radiant barrier installation in Bulverde typically runs $1,800-$3,200 for standard single-family homes, with larger Hill Country properties or complex rooflines reaching $3,800-$5,500.
How we do it
We staple perforated aluminum foil across bottom chords of roof trusses, maintaining ventilation channels and ensuring at least 3/4-inch air gap for reflectivity to function, then photograph full coverage before closing.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing or have decking exposed for other work, and you want the most effective radiant barrier configuration rather than retrofitting beneath existing shingles.
What it costs in Bulverde
Radiant barrier roof deck application during construction or re-roofing in Bulverde typically costs $2,200-$4,000, with spray-applied radiant coatings on complex geometries reaching $4,500-$6,500.
How we do it
We apply foil-faced OSB or spray low-emissivity coating directly to roof decking before shingle installation, ensuring continuous coverage and proper attic ventilation integration per manufacturer specifications.
What Radiant Barrier Installation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Attic radiant barrier (retrofit) | $1,800 - $3,200 |
| Radiant barrier roof deck | $2,200 - $4,000 |
| Spray-applied radiant coating | $4,500 - $6,500 |
Does radiant barrier work with spray foam in Bulverde?
Yes - in conditioned attics, we install radiant barrier on roof decking before applying open-cell spray foam, getting both reflectivity and air-sealing performance. The combination typically drops attic temperature 25-35°F compared to unimproved spaces.
How long until I see savings from radiant barrier in Bulverde?
Most Bulverde homeowners see reduced HVAC runtime within the first billing cycle. Call (830) 402-5240 for a free estimate - we’ll measure your attic and give you a written price before any work starts.
Insulation Removal & Replacement in Bulverde

Bulverde’s relatively new housing stock creates a specific removal scenario: homes under 15 years old with builder-grade insulation that settled, got compressed by storage or trades, or was contaminated by roof leaks or rodent activity. In Timberwood Park and Johnson Ranch, we’ve pulled fiberglass from 2018 builds that was already below R-22 effective value - not because the material failed, but because it was installed thin and never inspected. Insulation Removal & Replacement is the full process.
Attic Insulation Removal
Signs you need it
Your attic insulation is visibly compressed below joist tops, has dark staining from past leaks, or you’ve had roofers walking through it for repairs.
What it costs in Bulverde
Attic insulation removal in Bulverde typically runs $1,500-$3,000 for standard homes, with larger attics or heavily compacted material requiring additional labor reaching $3,500-$5,000.
How we do it
We use commercial vacuums with HEPA filtration to remove all existing material, bag it for proper disposal, inspect decking and penetrations for damage, then document the clean cavity with photos before any new installation.
Contaminated Insulation Removal
Signs you need it
You smell ammonia or mustiness from the attic, see rodent droppings, or have had confirmed wildlife activity that has soiled the insulation material.
What it costs in Bulverde
Contaminated insulation removal with sanitizing in Bulverde typically costs $2,500-$4,500, with extensive contamination or multiple attic zones reaching $5,000-$7,500.
How we do it
We remove all contaminated material under negative air pressure, apply EPA-registered sanitizer to decking and framing, install physical barriers at entry points, then provide photo documentation of the decontaminated cavity before reinsulating.
What Insulation Removal & Replacement Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Standard attic removal | $1,500 - $3,000 |
| Contaminated removal with sanitizing | $2,500 - $4,500 |
| Removal + replacement to R-38 | $3,500 - $6,500 |
Can you remove insulation without replacing it the same day in Bulverde?
Yes - we complete removal and sanitizing, then schedule replacement after you’ve reviewed the clean attic photos and approved the scope for new material. Written price covers each phase separately.
Is it cheaper to remove and replace or just add more insulation in Bulverde?
Adding over compressed or contaminated material wastes money - new insulation can’t perform when underlying layers are compromised. Call (830) 402-5240 and we’ll inspect; if removal isn’t needed, we’ll tell you.
Attic Air Sealing in Bulverde

Bulverde’s production homes from the 2000s-2020s share a common construction pattern: top plates, electrical penetrations, and can light housings were never sealed before insulation went in, creating a chimney effect that pulls conditioned air into the attic year-round. In Climate Zone 2, that leakage means your HVAC is cooling 140°F attic air that’s constantly infiltrating downward while your paid-for conditioned air escapes upward. Attic Air Sealing is our core methodology.
Top Plate & Penetration Sealing
Signs you need it
Your blower door reading is above 3,000 CFM50 for a home under 3,000 square feet, or you feel drafts at interior wall tops during winter.
What it costs in Bulverde
Top plate and penetration sealing in Bulverde typically runs $1,200-$2,500 for standard production homes, with larger or more complex attic layouts reaching $2,800-$4,200.
How we do it
We access each top plate through insulation, apply fire-rated caulk or foam sealant to all gaps, seal wire and pipe penetrations, and verify with blower door running to confirm reduction in air leakage before closing.
Can Light & Duct Boot Sealing
Signs you need it
You have recessed can lights in ceilings below the attic, or your HVAC duct boots show dust streaking at ceiling connections indicating air leakage.
What it costs in Bulverde
Can light and duct boot sealing in Bulverde typically costs $800-$1,800 depending on fixture count, with extensive LED retrofits or hard-to-access boots reaching $2,200-$3,000.
How we do it
We install pre-fabricated fire-rated covers over each can light, seal with fire-rated caulk, then mastic-seal all duct boot connections to ceiling drywall while blower door confirms leakage reduction.
What Attic Air Sealing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Top plate & penetration sealing | $1,200 - $2,500 |
| Can light & duct boot sealing | $800 - $1,800 |
| Full attic air sealing package | $2,200 - $4,500 |
Do you seal before or after adding insulation in Bulverde?
Always before - we never blow insulation over an unsealed attic floor. Sealing first lets the blower door verify our work; adding insulation first buries the leaks and makes them impossible to test.
Will air sealing alone help my Bulverde home?
Yes - we regularly see 20-35% reduction in air leakage from sealing alone, which directly reduces HVAC runtime. Call (830) 402-5240 for a blower door test and written price for the sealing scope.
Wall Insulation in Bulverde

Bulverde’s production homes were built with fiberglass batts in exterior walls, installed quickly by framing crews who left gaps at electrical boxes, compressed material around plumbing, and missed entire stud bays. In Climate Zone 2, those gaps become thermal bypasses that let summer heat radiate through walls while your AC runs continuously. We find the worst wall performance in two-story homes where the second floor never reaches setpoint despite seemingly adequate attic insulation. Wall Insulation covers our retrofit approaches.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, your second floor has a 5°F+ temperature split from downstairs, or an infrared camera shows framing members as cold stripes in winter.
What it costs in Bulverde
Injection foam wall insulation in Bulverde typically runs $3,500-$6,000 for standard single-story homes, with two-story homes or those with complex wall geometry reaching $6,500-$10,000.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud-bay spacing, inject slow-rise foam that fills around obstructions, then plug and finish holes to match existing surfaces.
Drill & Fill Wall Insulation
Signs you need it
You have empty stud bays from original construction misses, or you’re remodeling and have wall cavities open that can be filled before closing.
What it costs in Bulverde
Drill and fill with dense-pack cellulose in Bulverde typically costs $2,800-$5,000 for partial homes, with full exterior wall retrofits reaching $5,500-$8,500.
How we do it
We access each stud bay through minimal holes, blow GreenFiber cellulose to 3.5 pounds per cubic foot density for no-settle performance, then seal and finish all access points with matched materials.
What Wall Insulation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Injection foam (single-story) | $3,500 - $6,000 |
| Drill & fill cellulose (partial) | $2,800 - $5,000 |
| Full exterior wall retrofit | $5,500 - $10,000 |
Can you insulate walls without removing drywall in Bulverde?
Yes - injection foam and dense-pack cellulose both install through small holes that we patch and finish. Most jobs complete in two days with minimal interior disruption.
Does wall insulation help with sound in Bulverde?
Dense-pack cellulose provides significant sound dampening between rooms and from exterior noise. Call (830) 402-5240 if you’re specifically targeting sound control - we’ll specify the right density and material.
Attic Cleaning & Rodent Proofing in Bulverde

Bulverde’s Hill Country interface means attics here face specific wildlife pressure: roof rats and squirrels exploit construction gaps in production homes, especially where builders left unsealed eave returns and pipe penetrations. Combined with the extreme attic temperatures that degrade insulation and accelerate organic breakdown, a single season of rodent activity can render a 2020 build’s attic uninhabitable and its insulation contaminated. Attic Cleaning & Rodent Proofing is our complete response.
Attic Sanitizing & Decontamination
Signs you need it
You smell urine or decay from the attic access, see droppings on insulation surface, or have had pest control confirm rodent activity that has since been trapped out.
What it costs in Bulverde
Attic sanitizing and decontamination in Bulverde typically runs $1,800-$3,500 for standard contamination, with extensive soiling or multiple pest species reaching $4,000-$6,500.
How we do it
We remove all contaminated insulation under negative pressure, HEPA-vacuum decking and framing, apply enzymatic sanitizer to break down organic residue, then provide photo documentation of the decontaminated space before any new work.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find gnawed siding or soffit vents, or have had recurring pest control visits that never addressed how rodents enter the structure.
What it costs in Bulverde
Rodent proofing and exclusion in Bulverde typically costs $1,500-$3,000 for standard single-family homes, with complex rooflines or multiple entry points reaching $3,500-$5,500.
How we do it
We inspect every roof and foundation penetration, install 1/4-inch hardware cloth over vents, seal all gaps larger than 1/4 inch with rodent-resistant materials, and provide photo documentation of every exclusion point with written warranty.
What Attic Cleaning & Rodent Proofing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Attic sanitizing & decontamination | $1,800 - $3,500 |
| Rodent proofing & exclusion | $1,500 - $3,000 |
| Full attic restoration (cleanout + proofing + reinsulation) | $4,500 - $9,000 |
Do you trap rodents or just seal the entry points in Bulverde?
We exclude and proof - we don’t trap. We recommend a pest control partner handle active infestations first, then we seal every entry so they can’t return. Our exclusion work carries a written warranty.
How do I know if my attic insulation is contaminated in Bulverde?
Dark staining, ammonia smell, or visible droppings are clear indicators. Call (830) 402-5240 and we’ll inspect with photo documentation - estimates are free, and we provide a written price before any work starts.
Home Energy Audit in Bulverde

Bulverde homeowners with inexplicably high Pedernales Electric or GVEC bills often suspect the HVAC system, but the real problem is usually the building envelope: unsealed attics, underperforming insulation, and duct leakage in 140°F attic cavities. A home energy audit identifies which of these factors dominates your specific home’s load, so you’re not replacing a perfectly good heat pump when the real issue is a leaky attic floor. Home Energy Audit is our diagnostic service.
Blower Door Test
Signs you need it
Your home feels drafty despite closed windows, your HVAC runs constantly, or you’re considering major insulation work and want a baseline to verify improvement.
What it costs in Bulverde
A standalone blower door test in Bulverde typically runs $350-$550, with full diagnostic audits including thermal imaging and duct testing reaching $600-$950.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, measure CFM50 leakage rate, then use smoke pencils and thermal imaging to locate dominant leakage paths while documenting findings with photos.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach temperature, suspect missing insulation in walls or ceilings, or want visual proof of envelope problems before committing to repairs.
What it costs in Bulverde
Thermal imaging inspection in Bulverde typically costs $250-$450 as a standalone service, or it’s included in our full energy audit package at $600-$950.
How we do it
We scan all envelope surfaces with FLIR cameras during blower door depressurization to reveal insulation gaps, air leakage patterns, and moisture issues, then provide timestamped images with annotations in your written report.
What Home Energy Audit Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Blower door test (standalone) | $350 - $550 |
| Thermal imaging inspection | $250 - $450 |
| Full home energy audit | $600 - $950 |
What does a home energy audit include in Bulverde?
Our full audit includes blower door test, thermal imaging, insulation inspection, duct leakage test, and written report with prioritized recommendations and estimated savings. Every audit gets photo documentation and a written scope for any proposed work.
Can I use audit results for utility rebates in Bulverde?
Yes - Pedernales Electric Cooperative and some HVAC rebate programs accept third-party blower door and duct test results. Call (830) 402-5240 and we’ll explain which tests qualify for your specific utility.
