Insulation in New Braunfels, TX
Crawl space encapsulation and vapor barrier installation in New Braunfels typically runs $3,200-$7,800 for most homes, with jobs in river-corridor neighborhoods like Gruene and along the Guadalupe often requiring enhanced moisture control. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in, with before-and-after blower-door numbers published on every applicable job. If you’re seeing musty odors, sagging insulation, or energy bills that spike with humidity, call us at (830) 402-5240 for a written price before any work starts.
Why New Braunfels Homes Are Different
New Braunfels sits at the Balcones Escarpment, a thermal transition zone that subjects homes to San Antonio-level summer heat hitting 98-103°F, then punishes them with Blue Norther cold fronts that drop temperatures 40 degrees overnight. This swing range means insulation systems here must perform at both extremes, unlike Hill Country homes just west that deal with drier, more stable conditions.
The housing stock tells the same two-part story. Veramendi, Meyer Ranch, and Hunter’s Creek produced thousands of production-built homes from 2005-2020, most insulated to minimum Texas energy-code standards with R-30 or less in attics and basic fiberglass batts in walls. Those homes are now 5-15 years old, their blown-in attic insulation settled and compressed, and their first-time owners - many Texas transplants - are seeing summer electric bills they’ve never experienced before. Meanwhile, the 19th-century limestone masonry buildings in Gruene and downtown present an entirely different challenge: dense stone walls with virtually no cavity and poor inherent thermal resistance, where retrofitting demands techniques never needed in the surrounding tract neighborhoods.
The Guadalupe and Comal river corridors add another variable. Valley-floor neighborhoods carry elevated localized humidity that makes vapor-barrier details critical. In dryer Hill Country just miles west, a standard install might suffice; here, moisture management separates jobs that last from jobs that fail.
Our Main New Braunfels Services
Most calls we get from New Braunfels homeowners center on attic upgrades and spray foam applications, though blown-in remains popular for cost-conscious retrofits in the production-built subdivisions. Here’s what each service addresses locally:
Attic Insulation in New Braunfels
Attic insulation in New Braunfels most often means adding depth to R-30 or less original installs in Veramendi, Meyer Ranch, and Hunter’s Creek homes now hitting their 5-15 year compression point. We start with a blower-door test to measure air leakage, seal top plates and penetrations, then install Owens Corning or Johns Manville products to bring attics to R-49 or R-60. Every job gets a written price upfront and documented photo record at completion. Attic Insulation in New Braunfels covers full project details and typical ranges.
Spray Foam Insulation in New Braunfels
Spray foam insulation in New Braunfels solves two distinct problems: the open-cavity limestone walls in Gruene historic buildings where no other retrofit is viable, and the rim joists and bonus-room kneewalls in production homes where fiberglass batts never sealed properly. We use Icynene and Demilec products, applied after air sealing is complete, with before-and-after blower-door numbers to verify the envelope improvement. Spray Foam Insulation in New Braunfels has application-specific pricing and performance data.
Blown-In Insulation in New Braunfels
Blown-in insulation in New Braunfels is the most common upgrade for settled original installs in 2005-2020 production homes, where fiberglass or cellulose has compressed to well below labeled R-value. We use GreenFiber cellulose or Owens Corning fiberglass, blown over sealed attic floors after blower-door testing establishes the baseline. It’s the cost-effective path for homeowners seeing their first shock summer bill. Blown-In Insulation in New Braunfels breaks down material options and project scope.

Crawl Space Encapsulation & Vapor Barrier in New Braunfels
Crawl space encapsulation and vapor barrier installation in New Braunfels addresses a problem amplified by the Guadalupe and Comal river corridors: elevated humidity in valley-floor neighborhoods that standard vented crawl spaces were never designed to handle. Production homes in Veramendi and Meyer Ranch built to minimum code often have thin 6-mil poly sheeting, if any, over bare earth, and by year 5-10 that sheeting is torn, displaced, or breeding mold. Crawl Space Encapsulation & Vapor Barrier covers our full protocol; here’s how we handle New Braunfels conditions specifically.
Crawl Space Vapor Barrier
Signs you need it
White or black mold on floor joists, musty odors entering living spaces through gaps around plumbing, or insulation batting falling from between joists due to moisture weight.
What it costs in New Braunfels
Most New Braunfels crawl space vapor barrier replacements run $1,800-$3,400 for homes under 2,500 square feet, with river-corridor properties sometimes requiring thicker 20-mil reinforced polyethylene due to higher soil moisture.
How we do it
We remove existing damaged poly, grade the earth surface, seam-seal 12-20 mil reinforced polyethylene across the entire footprint, and seal perimeter edges to foundation walls with butyl tape before inspecting with a moisture meter.
Crawl Space Encapsulation
Signs you need it
Chronic humidity readings above 70% in the crawl space, hardwood floor cupping visible from above, or pest activity concentrated in the damp, dark environment below.
What it costs in New Braunfels
Full crawl space encapsulation in New Braunfels typically ranges $4,500-$8,200 depending on foundation perimeter linear footage, with Gruene-area limestone foundations sometimes requiring custom wall sealing approaches.
How we do it
We install reinforced vapor barrier across floor and up walls to sill plate, seal all seams and penetrations, add mechanical dehumidification sized to cubic volume, and provide before-and-after humidity logging with the documented photo record.
What Crawl Space Encapsulation & Vapor Barrier Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Vapor barrier replacement (under 2,500 sq ft) | $1,800 - $3,400 |
| Full encapsulation with dehumidifier | $4,500 - $8,200 |
| Crawl space insulation (rigid foam board) | $2,200 - $4,600 |
Does crawl space encapsulation help with summer humidity in New Braunfels?
Yes. Encapsulation with mechanical dehumidification typically reduces crawl space relative humidity from 75-85% to 50-55%, which protects floor systems and reduces the load on your HVAC system. Call (830) 402-5240 for a free assessment of your crawl space conditions.
How long does crawl space encapsulation take in New Braunfels?
Most encapsulation projects finish in 2-3 days, with river-corridor homes sometimes needing an extra day for enhanced wall sealing due to limestone foundation conditions. We provide a written schedule with the written price before work starts.
Radiant Barrier Installation in New Braunfels
Radiant barrier installation in New Braunfels targets the specific heat gain pattern of 2005-2020 production homes: dark asphalt shingle roofs absorbing 98-103°F summer sun, then radiating that heat downward through R-30 attic insulation that was never designed to block radiant transfer. In Veramendi and Meyer Ranch, we regularly measure attic temperatures exceeding 140°F, with ductwork in those attics losing conditioned air before it reaches the vents. Radiant Barrier Installation details our full approach.
Attic Radiant Barrier
Signs you need it
Second-story rooms that stay 8-12°F hotter than the thermostat setting, or ducts sweating in the attic during peak summer afternoons.
What it costs in New Braunfels
Attic radiant barrier installation in New Braunfels runs $1,400-$2,800 for most production homes under 3,000 square feet, with complex attic geometries or existing insulation removal adding to labor.
How we do it
We staple perforated radiant barrier foil across bottom chords of roof trusses, maintaining ventilation channels, then verify with an infrared thermometer showing surface temperature reduction on the attic floor below.
Radiant Barrier & Ventilation
Signs you need it
Attic insulation that degrades prematurely due to chronic overheating, or power ventilators that run continuously without meaningful temperature reduction.
What it costs in New Braunfels
Radiant barrier combined with ventilation optimization typically costs $2,200-$4,000 in New Braunfels, including baffle installation and intake vent verification.
How we do it
We install radiant barrier, add or repair soffit baffles to preserve intake airflow, verify exhaust vent capacity matches attic volume, and document with thermal imaging showing the temperature differential achieved.
What Radiant Barrier Installation Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Attic radiant barrier (under 3,000 sq ft) | $1,400 - $2,800 |
| Radiant barrier with ventilation upgrade | $2,200 - $4,000 |
| Radiant barrier roof deck (new construction or reroof) | $1,800 - $3,200 |
Does radiant barrier work with existing attic insulation?
Yes. Radiant barrier complements existing insulation by blocking radiant heat transfer, the dominant heat gain mode in New Braunfels attics during summer; we install it without disturbing settled blown-in or batt insulation. Call (830) 402-5240 for a free evaluation of your attic’s heat gain profile.
How much cooler will my attic be with radiant barrier?
Most New Braunfels attics see a 20-35°F reduction in peak afternoon temperature, with the greatest impact on homes with dark shingles and minimal existing shade coverage.
Insulation Removal & Replacement in New Braunfels
Insulation removal and replacement in New Braunfels is most common in the 5-15 year old production homes of Veramendi, Meyer Ranch, and Hunter’s Creek, where original blown-in fiberglass or cellulose has compressed to 50-60% of labeled depth and no longer performs to R-value. We also handle contaminated removal in homes where roof leaks, rodent activity, or prior improper installation has made existing insulation a liability rather than an asset. Insulation Removal & Replacement covers our full removal protocol.
Attic Insulation Removal
Signs you need it
Insulation depth measuring less than half the original labeled R-value, or visible water staining and compression indicating past roof leaks.
What it costs in New Braunfels
Attic insulation removal in New Braunfels typically runs $1,200-$2,400 for homes under 2,500 square feet, with heavier settled density or limited attic access increasing labor time.
How we do it
We use commercial vacuums with HEPA filtration to remove all existing material, bag it for proper disposal, inspect decking for damage, and provide photo documentation of the clean substrate before any new insulation is specified.
Contaminated Insulation Removal
Signs you need it
Rodent droppings visible in insulation, urine odor detectable in living spaces, or fungal growth on insulation surfaces from chronic moisture intrusion.
What it costs in New Braunfels
Contaminated insulation removal with sanitizing runs $2,000-$3,800 in New Braunfels, with full attic decontamination and odor remediation adding to base removal cost.
How we do it
We remove contaminated material under negative air pressure, apply enzyme-based sanitizing agents to affected surfaces, verify with ATP testing, and only then specify replacement insulation matched to the sealed attic conditions.
What Insulation Removal & Replacement Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Standard attic insulation removal | $1,200 - $2,400 |
| Contaminated insulation removal with sanitizing | $2,000 - $3,800 |
| Insulation replacement (blown-in, R-49) | $2,400 - $4,200 |
Can you remove insulation without making a mess in my house?
Yes. Our removal process uses contained vacuum systems with hose runs directly to our truck, and we seal attic hatches and interior doorways with plastic sheeting to protect living spaces. Call (830) 402-5240 for a written price on removal and replacement.
Do I need to leave during insulation removal?
No. Most homeowners stay in the house during removal, though we recommend avoiding the immediate work zone; we schedule the noisiest vacuum work during hours that minimize disruption.
Attic Air Sealing in New Braunfels
Attic air sealing in New Braunfels is the foundation of every job we do, and it’s non-negotiable under The Haven Standard: we will never blow insulation over an unsealed attic floor. Production homes in Veramendi and Meyer Ranch were built with top plates, can lights, and duct boots left open to the attic, and in New Braunfels’s thermal transition zone those leaks cost homeowners conditioned air in both summer and winter. Attic Air Sealing details our sealing protocol.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling outlets and switches, or rooms that are consistently 5-10°F different from the thermostat setting despite adequate insulation depth.
What it costs in New Braunfels
Top plate and penetration sealing in New Braunfels runs $800-$1,600 for most production homes, with complex rooflines or multiple HVAC zones adding seal points.
How we do it
We locate all top plate gaps and wire/plumbing penetrations with blower-door-directed smoke, seal with fire-rated caulk and expanding foam, and verify with a post-sealing blower-door test showing CFM50 reduction.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that flicker in windy weather, or supply registers that blow noticeably cooler air in winter indicating attic air infiltration into the duct boot.
What it costs in New Braunfels
Can light and duct boot sealing typically adds $400-$900 to a New Braunfels attic air sealing job, with IC-rated can light covers and mastic-sealed duct boots specified per location.
How we do it
We install pre-formed covers over non-IC can lights, seal with fire-rated materials, apply mastic to all duct boot connections, and pressure-test the duct system where accessible to verify leakage reduction.
What Attic Air Sealing Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Top plate and penetration sealing | $800 - $1,600 |
| Can light and duct boot sealing | $400 - $900 |
| Full attic air sealing (comprehensive) | $1,400 - $2,600 |
Will air sealing alone lower my energy bills?
Yes. Most New Braunfels homes see 15-25% HVAC energy reduction from comprehensive attic air sealing, with the biggest impact on two-story production homes where stack effect drives significant winter heat loss. Call (830) 402-5240 for a blower-door test and written scope.
How do you measure air sealing results?
We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - before and after sealing, and we publish both figures on your documented job record.
Wall Insulation in New Braunfels
Wall insulation in New Braunfels presents two distinct challenges: the uninsulated or under-insulated 2×4 exterior walls in production homes built to minimum code, and the dense limestone walls in Gruene historic buildings with no stud cavity and virtually no retrofit path through conventional methods. We address both with techniques matched to the wall type, never applying a one-size-fits-all approach. Wall Insulation covers our full methodology.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that are cold to the touch in winter, or rooms with exterior walls that never reach thermostat temperature despite adequate attic insulation.
What it costs in New Braunfels
Injection foam wall insulation in New Braunfels runs $3,200-$5,800 for most production homes, with two-story walls or limited exterior access points increasing labor for hose routing.
How we do it
We drill 5/8″ holes through exterior siding or interior drywall at stud-bay intervals, inject slow-rise foam to fill the cavity without bowing framing, patch all access points, and verify density with thermal imaging.
Drill & Fill Wall Insulation
Signs you need it
Existing fiberglass batts that have settled or degraded in exterior walls, or walls with known gaps from incomplete original installation visible through thermal imaging.
What it costs in New Braunfels
Drill and fill wall insulation replacement in New Braunfels typically costs $2,800-$4,600, with stucco or masonry exterior finishes requiring more complex patching than vinyl or fiber-cement siding.
How we do it
We remove existing degraded material where accessible, drill and fill with dense-pack cellulose or fiberglass, seal all penetrations, and provide thermal imaging documentation showing reduced surface temperature variation.
What Wall Insulation Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Injection foam wall insulation | $3,200 - $5,800 |
| Drill and fill wall insulation | $2,800 - $4,600 |
| Exterior wall insulation (new construction or remodel) | $2,200 - $4,000 |
Can you insulate the limestone walls in Gruene historic homes?
Spray foam applied to the interior face of the stone is often the only viable retrofit, but we design the application carefully to avoid trapping moisture in the limestone and triggering efflorescence or spalling. Call (830) 402-5240 for a site-specific assessment.
Will wall insulation help with summer heat gain?
Yes. In New Braunfels’s 98-103°F summer conditions, insulating under-insulated 2×4 walls reduces radiant and conductive heat gain that overwhelms attic-only insulation strategies, particularly on west-facing walls.
Attic Cleaning & Rodent Proofing in New Braunfels
Attic cleaning and rodent proofing in New Braunfels addresses a problem we see frequently in the 5-15 year old production homes of Veramendi and Meyer Ranch: original construction left attic penetrations unsealed, and the combination of Hill Country wildlife pressure and accessible roof lines creates entry paths for rodents seeking shelter. Once inside, they compress and contaminate insulation, creating both a performance problem and an air quality concern. Attic Cleaning & Rodent Proofing covers our full protocol.
Attic Cleanout & Sanitizing
Signs you need it
Visible rodent droppings in attic insulation, compressed trails through blown-in material, or musty odors that intensify when HVAC systems run.
What it costs in New Braunfels
Attic cleanout and sanitizing in New Braunfels runs $1,600-$3,200 depending on contamination extent and attic square footage, with heavy soiling requiring additional enzyme treatment passes.
How we do it
We remove all contaminated insulation under contained conditions, apply hospital-grade sanitizing agents to affected surfaces, HEPA-vacuum the entire attic envelope, and provide photo documentation of the sanitized substrate before specifying replacement.
Rodent Proofing & Exclusion
Signs you need it
Recurring rodent activity after prior trapping or baiting, or visible gnaw marks around roof penetrations, soffit vents, or gable end screens.
What it costs in New Braunfels
Rodent proofing and exclusion in New Braunfels typically costs $900-$1,800 for production homes with standard roof complexity, with tile or metal roof profiles requiring specialized flashing detail.
How we do it
We inspect all roof and soffit penetrations with the homeowner present, seal entry points with rodent-resistant materials including steel mesh and concrete patch, install vent guards where needed, and provide a written exclusion map of all work performed.
What Attic Cleaning & Rodent Proofing Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Attic cleanout and sanitizing | $1,600 - $3,200 |
| Rodent proofing and exclusion | $900 - $1,800 |
| Full attic restoration (cleanout + proofing + insulation) | $4,200 - $7,400 |
How do I know if rodents are in my attic?
Listen for scratching or scurrying at dawn and dusk, check for droppings near attic hatches, and look for compressed trails or tunnels in blown-in insulation; we confirm with inspection and provide a written scope. Call (830) 402-5240 for a free attic assessment.
Will rodent proofing keep them out permanently?
Our exclusion work carries a 365-Day Done Right Promise: if rodents re-enter through any point we sealed, we return and correct it at no charge, with the exclusion map documenting every location addressed.
Home Energy Audit in New Braunfels
Home energy audit in New Braunfels gives homeowners the documented baseline they need before spending on any insulation upgrade, and it’s particularly valuable in this market where production homes were built to minimum code and transplants often don’t know what “normal” Texas energy consumption looks like. We run a full building-envelope assessment with blower-door testing, thermal imaging, and insulation inspection, then provide a written scope prioritized by cost-effectiveness. Home Energy Audit details our full audit protocol.
Blower Door Test
Signs you need it
Energy bills 30% or more above similarly sized homes in your neighborhood, or rooms that are consistently uncomfortable despite recent HVAC service.
What it costs in New Braunfels
A standalone blower-door test in New Braunfels costs $350-$550, with the fee credited toward any insulation or air-sealing work we perform within 90 days.
How we do it
We install a calibrated blower door in your front entry, depressurize the house to 50 Pascals, measure CFM50 leakage, and use smoke pencils and infrared cameras to locate the dominant leakage paths for written documentation.
Thermal Imaging Inspection
Signs you need it
Visible temperature variations on ceilings or walls, or suspicion of missing insulation in areas inaccessible to visual inspection.
What it costs in New Braunfels
Thermal imaging inspection bundled with a blower-door test runs $450-$700 in New Braunfels, with whole-house imaging including attic, walls, and foundation perimeter.
How we do it
We conduct interior and exterior thermal scans with a 320×240 resolution FLIR camera during appropriate temperature differentials, mark anomalous patterns on floor plans, and correlate findings with blower-door data to distinguish air leakage from missing insulation.
What Home Energy Audit Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Blower-door test (standalone) | $350 - $550 |
| Blower-door with thermal imaging | $450 - $700 |
| Comprehensive home energy audit | $600 - $950 |
Is a home energy audit worth it before insulating?
Yes. In New Braunfels’s production-home market, we’ve found that 40-60% of comfort problems stem from air leakage rather than insufficient insulation, and a $500 audit prevents spending $3,000 on the wrong fix. Call (830) 402-5240 to schedule; the fee applies to any work we perform.
What documentation do I get from a home energy audit?
You receive a written report with blower-door CFM50 readings, thermal images with temperature annotations, a prioritized scope of recommended work with estimated ranges, and the documented photo record of all inspection points.
