Most New Braunfels homes we work on sit on caliche or limestone terrain with crawl spaces that pull ground moisture straight into the floor system. The river-valley humidity from the Comal and Guadalupe, combined with rapid construction in neighborhoods like Veramendi and Creekside, left many crawl spaces with minimal vapor management. We seal first, then insulate, and we document every step.
Why New Braunfels Homes Are Different
New Braunfels has ranked among the fastest-growing cities in the United States for over a decade, and that growth produced a housing stock dominated by production-built tract homes from the 2010s-2020s boom. Builders insulated these homes to bare-minimum Texas Energy Code during frenzied buildout, and the results are showing up now in attics that hit 150°F on open limestone terrain with almost no mature shade cover.
The river corridor adds another layer. Homes near the Comal and Guadalupe deal with humidity levels that can degrade batt insulation’s effective R-value within a few years, especially in slab-on-grade construction where vapor management was an afterthought. After Winter Storm Uri in 2021, we fielded a wave of calls from owners of 5-10-year-old production homes in I-35 corridor subdivisions who discovered their builder-grade blown fiberglass had settled or was undersized from day one. The historic German-settlement core around downtown and Gruene presents the opposite problem: 19th- and early 20th-century limestone and frame structures with essentially no original wall insulation.
Our Main New Braunfels Services
These are the two services New Braunfels homeowners call about most, with blown-in rounding out the top three.
Attic Insulation in New Braunfels
Attic insulation in New Braunfels means dealing with extreme attic temperatures in open, treeless subdivisions on rocky caliche soil. We see the most demand in Veramendi, Creekside, and the Canyon Lake corridor, where production homes from the 2010s-2020s were insulated to code minimum with blown fiberglass. We start with air sealing of top plates and can lights, then add insulation that actually performs. Attic Insulation in New Braunfels
Spray Foam Insulation in New Braunfels
Spray foam insulation in New Braunfels has become the go-to upgrade for homeowners who lived through Winter Storm Uri and realized their builder-grade insulation wasn’t enough. We use open-cell and closed-cell formulations from Owens Corning and Demilec, applied after full air sealing, with before-and-after blower-door numbers on every job. The freeze-protection and summer-cooling benefits are measurable. Spray Foam Insulation in New Braunfels
Blown-In Insulation in New Braunfels
Blown-in insulation in New Braunfels is the most common retrofit for settled or undersized fiberglass in production-home attics. We use Johns Manville and Knauf fiberglass, or GreenFiber cellulose, blown to proper depth after sealing all attic-floor penetrations. Every job gets a written price before work starts and a Documented Photo Record when we’re done. Blown-In Insulation in New Braunfels

Before
AfterCrawl Space Encapsulation & Vapor Barrier in New Braunfels
Crawl space encapsulation and vapor barrier installation in New Braunfels addresses a specific regional problem: homes built quickly on limestone and caliche terrain during the 2010s-2020s construction boom, with crawl spaces that were never properly sealed against ground moisture. The river-valley humidity from the Comal and Guadalupe Rivers pushes vapor through bare earth crawl spaces year-round, raising floor-system moisture and creating conditions for mold, rot, and energy loss that batt insulation alone cannot fix. Crawl Space Encapsulation & Vapor Barrier is the service we recommend when a homeowner reports musty first-floor odors or cold floors in winter.
Crawl Space Vapor Barrier
Signs you need it
Your first floor smells musty in humid months, or you see condensation on ductwork running through the crawl space.
What it costs in New Braunfels
A 6-mil to 20-mil vapor barrier installed over bare earth typically runs $1,200-$2,800 for an average New Braunfels crawl space.
How we do it
We clear debris, seam-seal a reinforced polyethylene sheet across the entire floor, run it 6-12 inches up foundation walls, and seal all seams with pressure-sensitive tape.
Crawl Space Encapsulation
Signs you need it
You’re running a dehumidifier constantly, or your hardwood floors are cupping from below.
What it costs in New Braunfels
Full encapsulation with sealed vapor barrier, insulated walls, and conditioned-air supply typically runs $4,500-$9,500 in New Braunfels.
How we do it
We install a complete vapor barrier system, seal foundation vents, insulate walls with rigid foam, and add a dehumidifier or conditioned-air supply to maintain dry, stable air below the floor system.
What Crawl Space Encapsulation & Vapor Barrier Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Vapor barrier (6-20 mil, earth coverage only) | $1,200 - $2,800 |
| Partial encapsulation (barrier + wall sealing) | $3,500 - $5,500 |
| Full encapsulation (barrier, insulation, conditioning) | $4,500 - $9,500 |
How long does crawl space encapsulation take in New Braunfels?
Most vapor barrier jobs finish in one day; full encapsulation with wall insulation and conditioning equipment takes two to three days. We schedule with a written start date and a named crew.
Will encapsulation help with winter floor temperatures?
Yes - sealing the crawl space stops cold air infiltration and allows floor insulation to perform at rated R-value instead of being bypassed by wind. Call (830) 420-0953 for a free estimate.
Radiant Barrier Installation in New Braunfels
Radiant barrier installation in New Braunfels is a high-ROI upgrade for homes with unconditioned attics that exceed 140°F on summer afternoons, which describes most production-built tract homes in Veramendi, Creekside, and I-35 corridor subdivisions. The open limestone terrain and minimal mature tree cover leave these attics exposed to solar gain that standard insulation alone cannot block, while the Hill Country heat radiating through roof decking adds thermal load that air conditioning runs longer to overcome.
Attic Radiant Barrier
Signs you need it
Your AC runs continuously after 2 p.m. in July, or the second story stays 8-12 degrees warmer than the first.
What it costs in New Braunfels
Attic radiant barrier installation typically runs $1,500-$3,200 for an average New Braunfels home.
How we do it
We staple perforated aluminum foil or spray low-emissivity coating to the underside of roof decking or across attic trusses, after air sealing and before adding insulation.
Radiant Barrier Roof Deck
Signs you need it
Your roof decking is visible from the attic and measures over 160°F with an infrared thermometer on summer afternoons.
What it costs in New Braunfels
Roof-deck radiant barrier application typically runs $2,000-$4,500 for an average New Braunfels roof.
How we do it
We spray a low-emissivity coating directly onto the roof deck after cleaning, or install foil-faced sheathing during re-roofing, then verify surface temperature reduction with thermal imaging.
What Radiant Barrier Installation Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Attic radiant barrier (foil, truss-mounted) | $1,500 - $3,200 |
| Radiant barrier roof deck (spray application) | $2,000 - $4,500 |
| Radiant barrier with attic air sealing package | $2,800 - $5,500 |
Does radiant barrier work with existing insulation?
Yes - we install radiant barrier after air sealing and before adding insulation, so both systems work together without compressing the thermal layer. Call (830) 420-0953 for a free estimate.
How much will my attic temperature drop?
Most New Braunfels attics see a 20-35 degree reduction in peak roof-deck temperature, with attic air temperature dropping 10-20 degrees depending on ventilation.
Insulation Removal & Replacement in New Braunfels
Insulation removal and replacement in New Braunfels has surged since Winter Storm Uri revealed how many 2010s-2020s production homes were built with undersized or poorly installed blown fiberglass. We regularly remove settled, contaminated, or moisture-damaged insulation from attics in Veramendi, Creekside, and Canyon Lake corridor subdivisions, then replace it with properly specified material after complete air sealing.
Contaminated Insulation Removal
Signs you need it
Your attic insulation smells musty, shows dark staining, or you’ve had a roof leak that soaked the fiberglass.
What it costs in New Braunfels
Contaminated insulation removal and disposal typically runs $1,800-$3,500 for an average New Braunfels attic.
How we do it
We bag and remove contaminated material with HEPA-contained vacuums, treat the attic deck with antimicrobial where needed, and document the bare deck with photos before installing new insulation.
Insulation Replacement
Signs you need it
Your insulation has settled below the top of the ceiling joists, or your energy bills have climbed 20% or more with no rate increase.
What it costs in New Braunfels
Insulation replacement with new blown fiberglass or cellulose typically runs $2,500-$5,500 for an average New Braunfels attic.
How we do it
We remove old material, seal all attic-floor penetrations, and install new insulation to proper depth with a written R-value target and blower-door verification.
What Insulation Removal & Replacement Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Contaminated insulation removal only | $1,800 - $3,500 |
| Insulation replacement (blown fiberglass/cellulose) | $2,500 - $5,500 |
| Full removal + replacement with air sealing | $4,000 - $7,500 |
Can you remove insulation with rodent contamination?
Yes - we remove rodent-contaminated insulation with full PPE and HEPA containment, then sanitize the attic deck before any new material goes in. Call (830) 420-0953 for a free estimate.
Do I need to leave the house during removal?
No - our vacuums are HEPA-contained and vented outside, so you can stay home; we seal the attic hatch and work from outside access where possible.
Attic Air Sealing in New Braunfels
Attic air sealing in New Braunfels is the single most cost-effective upgrade for production homes built during the 2010s-2020s boom, where volume builders often skipped sealing top plates, can lights, and duct boots to meet schedule. The combination of Hill Country temperature swings and river-valley humidity means every unsealed penetration is a pathway for conditioned air to escape and moisture to enter, driving up energy bills and degrading insulation performance.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at ceiling outlets in winter, or your blower-door test shows excessive air leakage at the attic floor.
What it costs in New Braunfels
Top plate and penetration sealing typically runs $1,200-$2,800 for an average New Braunfels home.
How we do it
We seal all top plates, wire penetrations, and plumbing stacks with fire-rated caulk and foam, then verify the reduction with a blower-door test.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in windy weather, or you see dust streaking around ceiling registers.
What it costs in New Braunfels
Can light and duct boot sealing typically runs $800-$2,200 for an average New Braunfels home.
How we do it
We install fire-rated covers over can lights, seal duct boots to drywall with mastic, and connect flex duct to boots with proper mechanical fasteners.
What Attic Air Sealing Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Top plate and penetration sealing | $1,200 - $2,800 |
| Can light and duct boot sealing | $800 - $2,200 |
| Complete attic air sealing package | $2,000 - $4,500 |
Will air sealing alone lower my energy bills?
Yes - most New Braunfels homes see 15-25% reduction in HVAC runtime after proper attic air sealing, before any insulation is added. Call (830) 420-0953 for a free estimate.
How do you prove the sealing worked?
We provide before-and-after blower-door numbers on every job - a pressurization reading that shows, in one figure, how much air your building envelope was losing before and after our work.
Wall Insulation in New Braunfels
Wall insulation in New Braunfels addresses two distinct housing stocks: the historic German-settlement core around downtown and Gruene, where 19th- and early 20th-century limestone and frame structures have essentially no original wall insulation, and the 2010s-2020s production homes where exterior walls were insulated to code minimum with batts that often have gaps, compression, or missing sections behind electrical boxes.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls are cold to the touch in winter, or you have rooms that never reach set temperature despite duct airflow.
What it costs in New Braunfels
Injection foam wall insulation typically runs $3,500-$7,500 for an average New Braunfels home.
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
You own a historic home in Gruene or downtown New Braunfels with empty wall cavities and plaster or lath construction.
What it costs in New Braunfels
Drill and fill wall insulation with cellulose or fiberglass typically runs $2,800-$6,000 for an average New Braunfels home.
How we do it
We drill access holes at the top and bottom of each stud bay, blow cellulose or fiberglass to proper density, and seal holes with matching material.
What Wall Insulation Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Injection foam wall insulation | $3,500 - $7,500 |
| Drill and fill (cellulose or fiberglass) | $2,800 - $6,000 |
| Exterior wall insulation with air sealing | $4,500 - $9,000 |
Can you insulate walls without removing drywall?
Yes - injection foam and drill-and-fill both work through small holes that we patch and texture-match, so no drywall removal is needed. Call (830) 420-0953 for a free estimate.
Does wall insulation help with summer cooling?
Yes - in New Braunfels, uninsulated or poorly insulated exterior walls transfer afternoon heat directly into living spaces, forcing longer AC runtime; proper wall insulation reduces that load measurably.
Attic Cleaning & Rodent Proofing in New Braunfels
Attic cleaning and rodent proofing in New Braunfels is common in the established neighborhoods and river-corridor homes where mature trees and proximity to greenbelt areas provide habitat for roof rats and squirrels. The 2010s-2020s production homes often have construction gaps at fascia boards and roof vents that rodents exploit, while older homes near Gruene and downtown have decades of accumulated debris and unsealed entry points.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia or musk from the attic hatch, or you’ve found rodent droppings in insulation during a storage trip.
What it costs in New Braunfels
Attic sanitizing and decontamination typically runs $1,500-$3,200 for an average New Braunfels attic.
How we do it
We remove contaminated insulation, HEPA-vacuum all surfaces, apply enzyme-based sanitizer to break down organic waste, and document the clean deck with photos.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in walls at dawn or dusk, or you’ve found gnawed fascia or chewed vent screens.
What it costs in New Braunfels
Rodent proofing and exclusion typically runs $1,200-$2,800 for an average New Braunfels home.
How we do it
We seal all entry points larger than 1/4 inch with rodent-proof materials, install hardware cloth over vents, and provide a written exclusion report with photos of every sealed gap.
What Attic Cleaning & Rodent Proofing Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Attic sanitizing and decontamination | $1,500 - $3,200 |
| Rodent proofing and exclusion | $1,200 - $2,800 |
| Full attic restoration (cleanout, sanitize, re-insulate) | $4,000 - $8,500 |
Do you handle the rodents or just seal the house?
We partner with licensed pest control for active infestations, then perform permanent exclusion and attic restoration so rodents cannot re-enter. Call (830) 420-0953 for a free estimate.
How do I know all entry points are sealed?
We provide a Documented Photo Record of every sealed gap and a written exclusion report; our 365-Day Done Right Promise covers any re-entry through our work.
Home Energy Audit in New Braunfels
Home energy audit in New Braunfels is the starting point we recommend for every production-built home from the 2010s-2020s boom, especially after Winter Storm Uri revealed how many were under-insulated from day one. A proper audit identifies where conditioned air is escaping, where insulation is underperforming, and whether river-valley humidity is degrading your building envelope - all with numbers you can see.
Blower Door Test
Signs you need it
Your energy bills are rising with no rate change, or rooms stay uncomfortable despite new HVAC equipment.
What it costs in New Braunfels
A standalone blower-door test typically runs $300-$600 in New Braunfels.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - a single number showing total air leakage.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation behind walls, or you want to verify air sealing results with visual evidence.
What it costs in New Braunfels
Thermal imaging inspection typically runs $250-$500 in New Braunfels.
How we do it
We scan the building envelope with an infrared camera during blower-door depressurization to locate air leaks and insulation gaps that are invisible to the eye.
What Home Energy Audit Costs in New Braunfels
| Item | Typical range in New Braunfels |
|---|---|
| Blower-door test (standalone) | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Full home energy audit (blower door, thermal, duct test, report) | $500 - $1,200 |
Will the audit tell me what to fix first?
Yes - you receive a prioritized scope ranked by cost-effectiveness, with estimated savings for each measure. Call (830) 420-0953 for a free estimate.
Do I need an audit before insulation work?
We require a blower-door test before and after any air sealing work so you can verify results; for insulation-only jobs, we still recommend it to avoid adding material over hidden leaks.
