Insulation in Bulverde, TX
Crawl space encapsulation and vapor barrier installation in Bulverde typically runs $3,200-$6,800 for a full encapsulation, with most jobs completed in two days. We’re Envelope Insulation Co., and we’ve sealed and insulated more than 9,000 homes since 2016 under The Haven Standard - every one starting with a written price and closing with a documented record. In Bulverde, our crews find that even 8-year-old homes in communities along TX-46 were built to minimum code with vented crawl spaces that trap Hill Country humidity against floor joists. Call (830) 243-6352 for a free estimate with upfront pricing.
Why Bulverde Homes Are Different
Bulverde sits at the Balcones Escarpment edge of the Texas Hill Country, where attic temperatures routinely exceed 150°F in summer due to intense solar gain on dark roofing and the elevated, exposed terrain with minimal urban shade. The area also experiences periodic hard freezes - most dramatically in February 2021 - that expose the inadequacy of minimum-code wall and attic insulation in a climate with extreme swings at both ends.
The overwhelming majority of Bulverde’s homes are newly built single-family construction in master-planned communities along the TX-46 and Bulverde Road corridors - predominantly slab-on-grade with vented attics insulated to the minimum R-38 code using blown fiberglass. The speed of development means builders consistently chose the cheapest compliant options, leaving a large inventory of technically “new” homes that perform poorly under real Hill Country conditions. Contractors here frequently find vented attic assemblies in 8-12-year-old homes where the blown fiberglass has settled unevenly and the ridge venting is insufficient for the hilltop exposure.
Our Main Bulverde Services
These are the three services Bulverde homeowners call about most often.
Attic Insulation in Bulverde
Most Bulverde attics we inspect have blown fiberglass that has settled below the joist tops, creating thermal bridges where conditioned air escapes into the vented cavity. We remove or supplement existing material, seal top plates and penetrations first, then install to the correct depth for the Hill Country climate. Every job gets a written price before work starts and a Documented Photo Record when we leave. Attic Insulation in Bulverde covers the full scope.
Spray Foam Insulation in Bulverde
Converting vented attics to unvented spray foam assemblies is a bread-and-butter job in Bulverde in ways it simply isn’t in flatter, older San Antonio neighborhoods. The hilltop exposure and insufficient ridge venting in many 2010s tract homes make closed-cell or open-cell foam on the roof deck a measurable upgrade. We publish before-and-after blower-door numbers so you can verify the air-sealing result. Spray Foam Insulation in Bulverde has the details.
Blown-In Insulation in Bulverde
For homeowners who want to improve R-value without converting the attic assembly, blown-in fiberglass or cellulose from Owens Corning, Johns Manville, or GreenFiber adds depth over settled existing material. We air seal first - always - then blow to uniform depth with depth markers at multiple points. The job closes with photos and a written scope. Blown-In Insulation in Bulverde explains the process.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Bulverde
Bulverde’s rapid growth produced thousands of slab-on-grade homes, but the remaining pier-and-beam and raised-slab construction - especially in earlier phases off Bulverde Road - sits on crawl spaces that vent directly to humid Hill Country air. In summer, that warm moisture rises through the floor system; in winter, cold drafts from unsealed crawl spaces make the first floor uncomfortable even when the thermostat reads 72. Crawl Space Encapsulation & Vapor Barrier is the service hub for everything below-grade.
Crawl Space Vapor Barrier
Signs you need it
Your first floor feels damp in summer, you smell mustiness from floor registers, or you see condensation on ductwork in the crawl space.
What it costs in Bulverde
A 6-mil to 20-mil vapor barrier installed over bare earth in a typical Bulverde crawl space runs $1,800-$3,400.
How we do it
We remove debris, grade the floor for drainage, seam-seal the polyethylene sheeting at all overlaps, and mechanically fasten it to foundation walls six inches above outside grade.
Crawl Space Encapsulation
Signs you need it
You’re running a dehumidifier upstairs year-round, hardwood floors are cupping, or insulation batts between joists are sagging and mold-stained.
What it costs in Bulverde
Full encapsulation with sealed vapor barrier, wall insulation, and conditioned-air supply in a Bulverde crawl space typically costs $3,200-$6,800.
How we do it
We seal all vents, install a reinforced vapor barrier across floor and walls, insulate rim joists with closed-cell foam, and add a dehumidistat-controlled dehumidifier or supply-air tap.
What Crawl Space Encapsulation & Vapor Barrier Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Vapor barrier (6-20 mil, floor only) | $1,800 - $3,400 |
| Full encapsulation with dehumidification | $3,200 - $6,800 |
| Rim joist spray foam add-on | $900 - $1,600 |
How long does crawl space encapsulation take in Bulverde?
Most Bulverde encapsulations finish in two days; larger crawl spaces or those requiring mold remediation first may take three. We give you a written schedule with the price before anyone starts.
Will encapsulation help with winter floor cold in Bulverde?
Yes - sealing vents and insulating rim joists stops the 40-50°F air that blows under pier-and-beam homes during Hill Country cold snaps. Call (830) 243-6352 for a free inspection and written price.
Radiant Barrier Installation in Bulverde
Bulverde’s hilltop exposure and dark architectural shingles create attic conditions that destroy the effectiveness of minimum-code insulation. When roof decking reaches 170°F in August, standard R-38 fiberglass conducts heat into the conditioned space regardless of its labeled rating. A radiant barrier - reflective foil or paint applied to the roof deck or rafters - blocks radiant heat transfer at the source, reducing attic temperatures by 20-35°F and cutting cooling load measurably. Radiant Barrier Installation covers all configurations.
Attic Radiant Barrier
Signs you need it
Your AC runs continuously from 2-7 p.m. in summer, upstairs rooms are 8-12°F warmer than downstairs, or ductwork in the attic feels hot to the touch.
What it costs in Bulverde
Radiant barrier foil stapled to rafters or laid over attic insulation in a typical Bulverde home runs $1,400-$2,800.
How we do it
We install perforated foil across rafter bays or drape it over existing insulation, maintaining ventilation paths and avoiding compression that would reduce the insulation’s R-value.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing roofing and want the radiant barrier bonded directly to the deck for maximum reflectivity and durability.
What it costs in Bulverde
Radiant barrier roof deck installation during re-roofing or as a standalone retrofit in Bulverde costs $2,200-$4,000.
How we do it
We apply foil-faced sheathing or liquid radiant barrier coating directly to the roof deck, sealing seams and ensuring the reflective surface faces the attic air space.
What Radiant Barrier Installation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Attic radiant barrier (foil over insulation) | $1,400 - $2,800 |
| Radiant barrier roof deck application | $2,200 - $4,000 |
| Radiant barrier with attic air sealing package | $2,800 - $5,200 |
Does radiant barrier work with spray foam in Bulverde?
In unvented spray foam attics, radiant barrier is redundant - the foam itself blocks conductive and radiant heat. We only recommend it for vented attic assemblies. Call (830) 243-6352 and we’ll tell you which configuration your home has.
How much can radiant barrier lower my cooling bill in Bulverde?
Most Bulverde homeowners see 8-15% summer cooling reduction after proper radiant barrier installation, with the greatest impact on homes with dark shingles and poor attic ventilation. Your actual savings depend on duct location and existing insulation condition.
Insulation Removal & Replacement in Bulverde
The speed of Bulverde’s development meant builders often used the cheapest compliant insulation, and we’ve found 10-year-old attics where fiberglass has settled 30% below labeled depth or been compromised by roof leaks the homeowner never noticed. Rodent activity in Hill Country homes is also more common than owners expect - we regularly remove insulation contaminated by droppings, nesting material, or urine that creates indoor air quality problems. Insulation Removal & Replacement is the full service page.
Contaminated Insulation Removal
Signs you need it
You’ve found rodent droppings in the attic, smelled ammonia near ceiling fixtures, or had a roof leak that saturated insulation batts.
What it costs in Bulverde
Contaminated insulation removal with HEPA containment and disposal in a typical Bulverde attic runs $2,000-$4,500.
How we do it
We set up negative-air containment, remove material with industrial vacuums, HEPA-filter the attic space, and apply antimicrobial treatment before any new insulation goes in.
Insulation Replacement
Signs you need it
Your attic insulation is below the joist tops, has visible water staining, or was installed before 2012 when Texas energy code requirements increased.
What it costs in Bulverde
Removal of old material plus new blown-in or batt insulation to current code in Bulverde typically costs $2,800-$5,500.
How we do it
We remove and dispose of existing material, air seal all penetrations, then install new insulation to proper depth with uniform coverage and depth markers.
What Insulation Removal & Replacement Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Contaminated insulation removal only | $2,000 - $4,500 |
| Removal + replacement with blown-in fiberglass | $2,800 - $5,500 |
| Removal + spray foam conversion | $5,500 - $11,000 |
Is it cheaper to remove and replace or just add more insulation in Bulverde?
If the existing material is dry, uncontaminated, and properly installed, topping off saves money. If it’s compressed, water-damaged, or rodent-compromised, removal is the only option that protects indoor air quality. We inspect and give you a written price for both scenarios.
How do I know if my Bulverde attic has contaminated insulation?
Dark trails through insulation (rodent runways), compressed tunnels in blown material, or musty smells from ceiling vents are clear indicators. Our inspection includes photos of any contamination - call (830) 243-6352 for a free assessment.
Attic Air Sealing in Bulverde
Bulverde’s 2010s tract homes were framed quickly and insulated to pass inspection, not to perform - and the top plates, electrical penetrations, and can light housings that connect conditioned space to vented attic were rarely sealed. During Winter Storm Uri, these leaks allowed heat to hemorrhage from homes that owners assumed were efficient, and in summer they let 150°F attic air infiltrate downward. Attic Air Sealing is the prerequisite we never skip.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling fixtures, cold drafts from outlets on exterior walls, or rooms that are 5-10°F different from the thermostat setting.
What it costs in Bulverde
Sealing top plates, wire penetrations, and plumbing stacks in a typical Bulverde attic runs $1,200-$2,400.
How we do it
We locate every penetration with blower-door-directed smoke, seal with fire-rated caulk or foam, and verify reduction with a post-sealing blower-door test.
Can Light & Duct Boot Sealing
Signs you need it
Can lights flicker in high winds, you feel conditioned air blowing from fixtures when the HVAC is off, or duct boots show rust from condensation.
What it costs in Bulverde
Sealing can light housings and duct boots with proper covers and mastic in Bulverde costs $800-$1,800.
How we do it
We install fire-rated covers over non-IC can lights, seal duct boots to drywall with mastic, and pressure-test the duct system for leakage.
What Attic Air Sealing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Top plate and penetration sealing | $1,200 - $2,400 |
| Can light and duct boot sealing | $800 - $1,800 |
| Full attic air sealing package | $2,200 - $4,200 |
Can attic air sealing be done without adding insulation in Bulverde?
Yes, and we recommend it as a standalone service when insulation depth is adequate but the thermal envelope leaks. The blower-door test proves the improvement - you’ll see the CFM50 number drop before any insulation is touched.
How much does air sealing lower my energy bills in Bulverde?
Most Bulverde homes we seal show 10-20% heating and cooling reduction, with the biggest gains in homes built 2010-2018 where construction speed prioritized speed over envelope tightness. Call (830) 243-6352 for a blower-door test and written price.
Wall Insulation in Bulverde
Bulverde’s master-planned homes from the 2010s and early 2020s were built with 2×4 exterior walls and R-13 fiberglass batts - the minimum Texas code allows - leaving exterior walls that conduct heat in summer and bleed it in winter. The Hill Country’s temperature swings, from 20°F winter lows to weeks of 100°F days, make wall R-value more critical here than in milder climates where minimum code was written. Wall Insulation covers retrofit options.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in afternoon sun, you have no insulation in exterior walls of a pre-2010 addition, or rooms with west-facing walls are unusable in August.
What it costs in Bulverde
Injection foam insulation for exterior walls in a typical 2,000-square-foot Bulverde home runs $3,500-$6,500.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam that fills cavities without bowing drywall, then patch and texture-match the holes.
Drill & Fill Wall Insulation
Signs you need it
Your walls have empty cavities from batts that settled or were never installed, or you’re remodeling and have drywall removed for access.
What it costs in Bulverde
Drill-and-fill with dense-pack cellulose in Bulverde exterior walls costs $2,800-$5,200 for a typical home.
How we do it
We access cavities through exterior siding or interior drywall, blow cellulose to 3.5 pounds per cubic foot density for no-settle performance, and seal all access points.
What Wall Insulation Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Injection foam (exterior walls) | $3,500 - $6,500 |
| Drill-and-fill dense-pack cellulose | $2,800 - $5,200 |
| Interior wall soundproofing | $1,800 - $3,400 |
Can you insulate walls without removing drywall in Bulverde?
Yes - injection foam and dense-pack cellulose both use small access holes that we patch and texture-match. The only walls that need drywall removal are those with obstructions or balloon framing. We’ll inspect and tell you which method applies.
Does wall insulation help with sound in Bulverde homes?
Dense-pack cellulose and certain open-cell foams reduce exterior noise and interior sound transmission between rooms. For dedicated soundproofing, we use specific products and techniques - call (830) 243-6352 for a written scope and price.
Attic Cleaning & Rodent Proofing in Bulverde
The Hill Country’s oak mottes and limestone outcrops that make Bulverde attractive also support robust rodent populations, and we’ve found active infestations in attics of homes less than five years old. Builders’ minimum-code construction leaves gaps at eaves, ridge vents without hardware cloth, and unsealed penetrations that rats and mice exploit - especially after construction disturbs their ground habitat. Attic Cleaning & Rodent Proofing is the complete service.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in walls at dawn or dusk, find droppings in the attic, or see gnaw marks on fascia boards or vent screens.
What it costs in Bulverde
Rodent proofing with exclusion work for a typical Bulverde home runs $1,500-$3,200.
How we do it
We inspect every potential entry point from foundation to ridge, seal with rodent-proof materials, install hardware cloth over vents, and provide a written map of all exclusion work completed.
Attic Sanitizing & Decontamination
Signs you need it
There’s a persistent urine smell from ceiling fixtures, visible droppings in insulation, or you’ve had rodents removed and need the contamination addressed.
What it costs in Bulverde
Attic sanitizing and decontamination after rodent activity in Bulverde costs $1,800-$3,600.
How we do it
We remove contaminated insulation, HEPA-vacuum all surfaces, apply enzymatic sanitizer to break down organic material, and treat for parasites before any new insulation is installed.
What Attic Cleaning & Rodent Proofing Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Rodent proofing and exclusion | $1,500 - $3,200 |
| Attic sanitizing and decontamination | $1,800 - $3,600 |
| Full attic restoration (cleanout + proofing + re-insulation) | $4,500 - $8,500 |
How do I know rodents are gone before you re-insulate my Bulverde attic?
We require a two-week trap-clear period with zero activity before installing new insulation, and we warranty our exclusion work. If they get back in through our seals, we return at no charge under our 365-Day Done Right Promise.
Will insurance cover rodent damage cleanup in Bulverde?
Most homeowner policies exclude rodent damage, but some cover the decontamination if it’s tied to a covered peril like a roof leak. We document everything with photos for your adjuster. Call (830) 243-6352 and we’ll help you understand what’s claimable.
Home Energy Audit in Bulverde
A home energy audit in Bulverde reveals what minimum-code construction hides - the blower-door test quantifies exactly how much conditioned air your envelope loses, and thermal imaging shows where insulation is missing, compressed, or bypassed. For homeowners who want data before spending, the audit produces a prioritized scope with written prices for each improvement. Home Energy Audit explains the full protocol.
Blower Door Test
Signs you need it
Your energy bills are 30% higher than neighbors with similar homes, you feel drafts you can’t locate, or you’re considering insulation and want to know if air sealing is the bigger priority.
What it costs in Bulverde
A standalone blower-door test with written report in Bulverde runs $350-$600.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure.
Thermal Imaging Inspection
Signs you need it
Your home has hot or cold spots, you suspect missing insulation in walls, or you want documentation of conditions before and after improvement.
What it costs in Bulverde
Thermal imaging as part of a full energy audit in Bulverde costs $450-$750; standalone imaging runs $250-$400.
How we do it
We scan every surface with a FLIR camera during blower-door depressurization, when temperature differentials are maximized, and mark every anomaly on a floor plan.
What Home Energy Audit Costs in Bulverde
| Item | Typical range in Bulverde |
|---|---|
| Blower-door test with written report | $350 - $600 |
| Full energy audit (blower door + thermal imaging + insulation inspection) | $450 - $750 |
| Duct leakage test add-on | $200 - $350 |
Should I get an energy audit before insulating my Bulverde home?
Yes - an audit prevents spending on insulation where air sealing would deliver more improvement for less cost. In Bulverde’s minimum-code homes, we often find that sealing produces greater comfort gain than adding R-value.
What does the energy audit report include?
You receive blower-door CFM50 before and after any work we perform, thermal images with temperature readings, a written scope with flat prices for each recommendation, and a priority ranking based on cost-effectiveness. Call (830) 243-6352 to schedule.

FAQs About Insulation in Bulverde
Most insulation retrofit in Bulverde does not require a permit, but spray foam conversions and any structural modification do. We handle permit research as part of our written scope - you’ll know before work starts whether Comal County or your HOA requires documentation.
A live person answers our phones 24/7, and most Bulverde inspections are scheduled within 24-48 hours. Emergency situations - no heat after a freeze, active roof leaks into insulation - get same-day priority when possible.
Bulverde’s 2010s and 2020s homes were built to minimum Texas energy code with the cheapest compliant materials, not for Hill Country performance. Winter Storm Uri proved these homes hemorrhage heat, and summer attic temperatures over 150°F overwhelm minimum R-38. The age of the home does not determine its efficiency - the quality of the envelope does.

What Bulverde Customers Say
"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E."Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
- Ainsley P."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.
