Insulation in Bulverde, TX
Crawl space encapsulation and vapor barrier installation in Bulverde typically runs $3,200-$6,800 for most homes, with full encapsulations on larger Hill Country properties reaching the upper end. 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 freeze-exposed Hill Country elevation, an unsealed crawl space with bare earth and no vapor barrier pulls moisture upward through slab-adjacent framing and makes winter pipe failures more likely, especially in the post-2000 subdivisions that dominate local housing stock. Call (737) 227-6219 for a written price before any work starts.
Why Bulverde Homes Are Different
Bulverde sits at 1,100-1,400 feet on the Edwards Plateau edge, which means harder freezes and wider temperature swings than San Antonio just 25 miles south. The 2000s-2020s subdivision boom here filled the hills with 2,500-4,500 square foot homes built to a price point, not to Hill Country climate reality. Most carry R-30 blown fiberglass in the attic with minimal air sealing at top plates and can lights - adequate on paper, underperforming in practice.
The February 2021 Winter Storm Uri exposed the gap. Neighbors in better-sealed custom builds kept pipes flowing while owners of newer tract homes with leaky thermal envelopes faced burst lines and four-figure heating bills. That stone veneer on your Hill Country-style exterior? It’s typically a 1-inch non-structural façade over OSB with no continuous exterior insulation, so thermal bridging through dense stud framing remains hidden until an energy audit or infrared camera reveals it. We see this pattern on every third inspection in Bulverde.
Our Main Bulverde Services
Most calls from Bulverde homeowners start with attic performance or spray foam questions. Here’s what those jobs look like locally.
Attic Insulation in Bulverde
Attic insulation in Bulverde means addressing those steep-pitched, expansive unconditioned spaces common in Hill Country architecture. We start with a blower-door test to establish baseline leakage, seal top plates and penetrations, then install to the appropriate R-value for this elevation’s heating demand. Every job closes with documented before-and-after numbers. Attic Insulation in Bulverde details the full process.
Spray Foam Insulation in Bulverde
Spray foam insulation in Bulverde works best for open attic floors, rim joists, and the wall cavities of homes where thermal bridging through stone-veneer framing has been identified. We specify open-cell or closed-cell based on assembly location and moisture drive, never defaulting to one product. Spray Foam Insulation in Bulverde covers specifications and applications.
Blown-In Insulation in Bulverde
Blown-in insulation in Bulverde is the most common upgrade for post-2000 homes with settled or undersized existing fiberglass. We use Owens Corning or Johns Manville loose-fill, but only after air sealing is complete - blowing over an unsealed attic floor traps leakage pathways and wastes material. Blown-In Insulation in Bulverde explains our sequencing.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Bulverde
Most Bulverde homes sit on slab-on-grade foundations across the Comal County limestone shelf, but the properties that do have crawl spaces - often older builds or custom homes on sloped Hill Country lots - face a specific moisture problem. Bare earth in an unvented or poorly vented crawl space evaporates upward year-round, and Bulverde’s freeze-exposed winters mean that moisture hits cold floor joists and subflooring with particular force. We’ve documented 70%+ relative humidity in unencapsulated Bulverde crawl spaces during January cold snaps, the conditions that grow mold and rot rim joists. Crawl Space Encapsulation & Vapor Barrier covers our full methodology.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare earth or thin plastic sheeting, and you smell mustiness in first-floor rooms during humid months or see condensation on ductwork.
What it costs in Bulverde
A ground-only vapor barrier installation in Bulverde typically runs $1,800-$3,400 depending on crawl space square footage and obstacle density.
How we do it
We remove debris, grade the earth, lay 10-mil minimum reinforced polyethylene with sealed seams and perimeter attachment, then tape all penetrations before documenting with photos.
Crawl Space Encapsulation
Signs you need it
You’re seeing sagging insulation between joists, visible mold on wood surfaces, or your hardwood floors cup from below during summer humidity spikes.
What it costs in Bulverde
Full crawl space encapsulation in Bulverde, including walls and conditioning, typically ranges from $4,200-$8,600 for the footprint sizes common here.
How we do it
We install vapor barrier on ground and walls, seal vents and rim joist leaks, add mechanical dehumidification if indicated, and provide before-and-after humidity logging.
What Crawl Space Encapsulation & Vapor Barrier Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Ground vapor barrier only | $1,800 - $3,400 |
| Partial wall sealing with barrier | $3,200 - $5,500 |
| Full encapsulation with dehumidifier | $4,200 - $8,600 |
Can a vapor barrier alone fix my crawl space humidity?
Ground vapor barrier alone controls soil moisture evaporation but won’t address wall leakage or vented outdoor air; we measure both sources before recommending scope. Call (737) 227-6219 and we’ll read your crawl space with you - estimates are free.
How long does crawl space encapsulation take in Bulverde?
Most Bulverde crawl space encapsulations finish in two to three days, with full-wall jobs on larger Hill Country homes extending to four; we provide a written schedule with the price.
Radiant Barrier Installation in Bulverde
Bulverde attic temperatures exceed 150°F in July and August, and that radiant heat transfer through the roof deck makes second-story rooms unlivable and forces HVAC systems into constant recovery mode. Post-2000 homes here with dark shingles and minimal roof ventilation suffer most - the builder-grade package rarely included radiant barrier, and the steep pitches that look good from the street create enormous radiant surface area. We install radiant barrier as a standalone upgrade or paired with air sealing and insulation increases, always measuring attic ventilation adequacy first because a radiant barrier without sufficient exhaust airflow can trap moisture. Radiant Barrier Installation details product specifications.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms run 8-12 degrees hotter than downstairs, your AC cycles constantly after 2 PM, or ductwork in the attic feels hot to the touch.
What it costs in Bulverde
Attic radiant barrier installation in Bulverde typically costs $1,400-$2,800 for the truss configurations common in 2,500-4,000 square foot homes.
How we do it
We staple perforated radiant barrier foil across bottom chord of trusses, maintaining ventilation channels, and verify with infrared camera that surface temperatures dropped post-installation.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing or have decking access, and you want the most effective radiant barrier configuration rather than retrofitting below trusses.
What it costs in Bulverde
Radiant barrier applied directly to roof deck during construction or re-roofing in Bulverde runs $2,200-$4,100 depending on pitch complexity and square footage.
How we do it
We apply foil-faced OSB or spray-applied low-emissivity coating to the deck underside, ensuring all seams are taped and ventilation paths remain unobstructed.
What Radiant Barrier Installation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Attic truss-mounted radiant barrier | $1,400 - $2,800 |
| Roof deck application (new construction/re-roof) | $2,200 - $4,100 |
| Radiant barrier with attic air sealing package | $2,800 - $5,200 |
Does radiant barrier work with my existing insulation?
Radiant barrier complements but does not replace insulation - it blocks radiant heat transfer while fiberglass or foam slows conductive flow; we assess both before specifying. Call (737) 227-6219 for a written scope on your attic.
Will radiant barrier help my winter heating bills?
Radiant barrier primarily reduces summer cooling load in Bulverde’s climate; winter benefit is minimal, which is why we pair it with air sealing for year-round performance.
Insulation Removal & Replacement in Bulverde
Insulation removal in Bulverde is most often triggered by one of three conditions: rodent contamination in attics of homes near the greenbelt corridors, water damage from pipe bursts during 2021-style freeze events, or failed vermiculite in older pre-2000 builds. The post-2000 majority faces a different problem - builder-grade fiberglass compressed by storage traffic or HVAC contractors, settled below labeled R-value, sometimes with mold from undetected roof leaks. We don’t add new material over damaged old; removal and replacement starts with a written scope documenting what’s coming out and why. Insulation Removal & Replacement covers safe handling protocols.
Contaminated Insulation Removal
Signs you need it
You’re finding droppings in the attic, smelling ammonia when the HVAC runs, or seeing insulation compressed into tunnels and nesting material.
What it costs in Bulverde
Contaminated insulation removal and disposal in Bulverde typically runs $2,400-$4,600 depending on attic square footage and contamination extent.
How we do it
We set negative air pressure, remove material with HEPA-contained vacuums, apply antimicrobial treatment to substrates, and provide photo documentation before any new insulation is specified.
Insulation Replacement
Signs you need it
Your existing insulation is compressed below joist tops, visibly water-stained, or tested well below its labeled R-value during our inspection.
What it costs in Bulverde
Insulation replacement in Bulverde, including removal of old material and installation of new blown fiberglass or cellulose, typically ranges $3,600-$6,800.
How we do it
We remove old material completely, inspect and seal the attic floor, then install new insulation to specified depth with density verification and written R-value certification.
What Insulation Removal & Replacement Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Contaminated insulation removal only | $2,400 - $4,600 |
| Standard removal + replacement with blown fiberglass | $3,600 - $6,800 |
| Removal + spray foam replacement (open cell attic floor) | $5,200 - $9,400 |
Do I have to leave during insulation removal?
We ask homeowners to vacate during active removal of contaminated material; the HEPA-contained process takes four to six hours for most Bulverde attics, and we text when it’s clear to return. Call (737) 227-6219 to schedule around your day.
Can you match my existing insulation type?
We can match fiberglass, cellulose, or mineral wool, but we typically recommend upgrading during replacement since the attic is open and air sealing can be completed first.
Attic Air Sealing in Bulverde
Attic air sealing is the single highest-impact upgrade for most Bulverde homes because the post-2000 building boom prioritized insulation quantity over leakage control. We’ve blower-door tested homes in Bulverde subdivisions built in 2015 that leaked 4,500 CFM50 - nearly double what the same footprint should achieve with proper sealing at top plates, can lights, and duct boots. That leakage means heated air escapes to the attic in January, and 150°F attic air gets pulled into wall cavities in July. We seal first, then insulate, always, and we publish the before-and-after blower-door numbers so you see the performance change. Attic Air Sealing explains our sealing sequence.
Top Plate & Penetration Sealing
Signs you need it
You’re feeling drafts at exterior wall outlets, seeing dust streaks around ceiling fixtures, or your blower-door test shows excessive leakage at the attic floor plane.
What it costs in Bulverde
Top plate and penetration sealing in Bulverde typically costs $1,600-$3,200 for the wall lengths and fixture counts common in 2,500-4,000 square foot homes.
How we do it
We access top plates through the attic, seal all gaps with fire-rated caulk and foam, box and seal electrical and plumbing penetrations, and verify with blower-door test before leaving.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights flicker in wind, you feel conditioned air blowing into the attic around duct connections, or thermal imaging shows hot spots at ceiling fixtures.
What it costs in Bulverde
Can light and duct boot sealing in Bulverde runs $800-$1,800 depending on fixture count and whether boots require reconstruction or just mastic sealing.
How we do it
We install fire-rated covers over non-IC cans, seal with high-temperature caulk, apply mastic and mesh to all duct boots, and pressure-test the duct system if accessible.
What Attic Air Sealing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Top plate and penetration sealing | $1,600 - $3,200 |
| Can light and duct boot sealing | $800 - $1,800 |
| Full attic air sealing package | $2,400 - $4,600 |
How much does air sealing lower my bills?
Most Bulverde homeowners see 15-25% reduction in heating and cooling costs after comprehensive attic air sealing, with the highest returns on homes built 2000-2015; we estimate specific savings from your blower-door result. Call (737) 227-6219 for a written estimate.
Can air sealing be done without removing insulation?
We can work around existing insulation in some areas, but optimal sealing requires temporary relocation to access top plates fully; we include this in the written scope and price.
Wall Insulation in Bulverde
Wall insulation in Bulverde addresses the hidden thermal bridge that most homeowners never suspect: that handsome stone veneer is a 1-inch non-structural façade over OSB sheathing with no continuous exterior insulation, so every stud becomes a thermal short circuit. In summer, exterior sheathing hits 140°F and studs conduct that heat inward; in winter, the same pathway bleeds conditioned air outward. Attic upgrades alone won’t fix this - the wall assembly needs direct intervention. We use injection foam or drill-and-fill methods that don’t require exterior demolition, and we always infrared-verify fill completeness. Wall Insulation covers technical specifications.
Injection Foam Wall Insulation
Signs you need it
Your walls feel hot to the touch in summer, rooms on the north side are noticeably colder in winter, or an energy audit shows high exterior wall thermal transmission.
What it costs in Bulverde
Injection foam wall insulation in Bulverde typically runs $3,200-$6,400 for a 2,500-3,500 square foot home with standard stud spacing.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam to fill cavities completely, patch with matching interior texture, and verify with thermal imaging that no voids remain.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls are empty or contain settled cellulose from a 1970s retrofit, and you’re experiencing noise transmission or temperature stratification between rooms.
What it costs in Bulverde
Drill and fill with dense-pack cellulose in Bulverde costs $2,400-$4,800 for similar footprints, with GreenFiber cellulose as our standard specification.
How we do it
We remove minimal interior drywall or drill through exterior sheathing, blow cellulose to 3.5 pounds per cubic foot density, seal penetrations, and provide density test documentation.
What Wall Insulation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Injection foam (interior access) | $3,200 - $6,400 |
| Dense-pack cellulose drill & fill | $2,400 - $4,800 |
| Exterior wall insulation with sheathing removal | $5,600 - $10,200 |
Will wall insulation damage my interior finish?
Interior injection requires 2-inch holes every 16 inches that we patch and texture-match; we show you the repair plan in writing before starting. Call (737) 227-6219 to walk through the scope.
Can you insulate walls from outside without opening inside?
Exterior access is possible on some siding types but not stone veneer; we assess your specific cladding and framing before recommending approach and price.
Attic Cleaning & Rodent Proofing in Bulverde
Attic cleaning in Bulverde is frequently tied to the Hill Country’s wildlife pressure - homes near greenbelt corridors or with mature oak canopy see roof rat and squirrel access through construction gaps that builders never sealed. The post-2000 subdivision homes are particularly vulnerable because steep roof pitches create complex fascia intersections where flashing was rushed, and those same expansive attics provide undisturbed nesting territory. We don’t clean and leave - we find every entry point, seal with rodent-proof materials, and document the exclusion with photos so you know the pathway is closed. Attic Cleaning & Rodent Proofing covers our full protocol.
Attic Sanitizing & Decontamination
Signs you need it
You’re smelling urine or musk when the HVAC runs, finding droppings in insulation, or seeing fly activity in ceiling fixtures that suggests carrion or nesting material above.
What it costs in Bulverde
Attic sanitizing and decontamination in Bulverde typically costs $1,800-$3,600 depending on contamination area and whether substrate replacement is needed.
How we do it
We remove contaminated material under negative pressure, apply enzyme-based sanitizer to all surfaces, fog with antimicrobial where indicated, and provide photo documentation of clean substrates.
Rodent Proofing & Exclusion
Signs you need it
You’re hearing scratching at night, finding new droppings after previous cleanup, or seeing gnaw marks on fascia, vents, or garage door seals.
What it costs in Bulverde
Rodent proofing and exclusion in Bulverde runs $1,400-$2,800 for standard roofline and foundation sealing on typical Hill Country home configurations.
How we do it
We inspect every roof intersection, vent, pipe penetration, and foundation gap with the homeowner present, seal with steel mesh and concrete repair where needed, and warranty the exclusion for one year.
What Attic Cleaning & Rodent Proofing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Attic sanitizing and decontamination | $1,800 - $3,600 |
| Rodent proofing and exclusion | $1,400 - $2,800 |
| Full attic restoration (cleaning + exclusion + re-insulation) | $4,200 - $7,800 |
How do I know rodents are gone before you re-insulate?
We set monitoring devices, verify no activity for minimum seven days, and photograph sealed entry points before any new insulation goes in; the written scope specifies this sequence. Call (737) 227-6219 to schedule inspection.
Will rodents chew through spray foam?
Yes - spray foam is not rodent-proof, which is why we use steel mesh, concrete, and metal flashing for exclusion and never rely on foam alone at entry points.
Home Energy Audit in Bulverde
A home energy audit in Bulverde is the diagnostic starting point that most post-2000 homes here never received - builders delivered keys without blower-door testing, thermal imaging, or duct leakage verification. The result is homeowners who know their bills are high but can’t identify whether the problem is attic leakage, wall thermal bridging, duct loss to the garage, or all three. Our audit sequences blower-door testing, infrared scanning, and combustion safety checks to isolate the largest cost drivers, then delivers a written priority list with price ranges for each upgrade. Home Energy Audit details what’s included.
Blower Door Test
Signs you need it
Your energy bills are 30% or more above neighbors with similar homes, you feel drafts you can’t locate, or you’re planning insulation upgrades and want baseline performance data.
What it costs in Bulverde
A standalone blower-door test in Bulverde costs $350-$550; it’s included at no additional charge when bundled with a full energy audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 leakage, and use smoke pencils and infrared to map leak locations room by room.
Thermal Imaging Inspection
Signs you need it
You have rooms that won’t maintain temperature, suspect missing wall insulation, or want to verify that recent insulation work achieved complete coverage without voids.
What it costs in Bulverde
Thermal imaging inspection in Bulverde runs $400-$650 as a standalone service, or included in the full audit package.
How we do it
We scan all exterior walls, ceilings, and foundation areas with a calibrated infrared camera during heating or cooling season, identifying thermal anomalies and documenting with annotated images.
What Home Energy Audit Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Blower-door test (standalone) | $350 - $550 |
| Thermal imaging inspection (standalone) | $400 - $650 |
| Full home energy audit (all diagnostics) | $650 - $950 |
Does an energy audit include repair estimates?
Yes - every Bulverde audit concludes with a written priority list showing estimated cost ranges for each recommended upgrade, ranked by savings-to-investment ratio; no work starts without a separate written price. Call (737) 227-6219 to schedule.
How long does a home energy audit take?
Most Bulverde audits require three to four hours on site plus analysis time; you receive the written report within 48 hours, and we review it together by phone or text.
