Attic Insulation in New Braunfels - Same-Day Service, Done Right the First Time

Insulation in New Braunfels, TX

Crawl space encapsulation and vapor barrier work in New Braunfels typically runs $2,800-$6,500 for homes under 2,500 square feet, with most jobs completed in one to two days. The combination of humid Gulf air rolling up from the Balcones Escarpment and the city’s explosive post-2010 growth has left thousands of newer homes with vented crawl spaces that trap moisture against floor joists year-round. If you’re seeing condensation on ductwork or smelling mustiness rise through the floors in neighborhoods like Veramendi or Hunter’s Crossing, the fix starts below your feet, not in the attic. Call (830) 243-6352 and we’ll walk the crawl space with you, written price in hand.

Why New Braunfels Homes Are Different

New Braunfels has ranked among the fastest-growing cities in the entire US for over a decade, producing wave after wave of quickly-built tract homes in subdivisions like Veramendi, Hunter’s Crossing, and Elm Creek where builders installed code-minimum blown fiberglass (R-30 attic) to hit price points - not to handle 100°F+ Hill Country summers or sudden Arctic outbreaks like the February 2021 Winter Storm Uri that froze pipes across Comal County. This enormous inventory of 5-to-15-year-old under-insulated homes concentrated along the I-35 growth corridor is the dominant insulation opportunity here, at a scale that simply does not exist in slower-growing neighbors like Seguin or Lockhart.

The vast majority of New Braunfels’s housing stock is post-2005 slab-on-grade construction in master-planned subdivisions, built during aggressive growth phases with builder-grade batt or blown fiberglass at code minimums to compete on sale price. A smaller secondary stock of 1970s-1990s ranch homes and a handful of historic German-era structures near downtown Gruene present retrofit and air-sealing challenges not found in the newer builds. Homes near the Guadalupe and Comal River corridors also experience measurably higher ambient humidity, compounding attic moisture risk in poorly vapor-managed insulation assemblies.

Insulation contractors working the post-2010 subdivisions along FM 306 and FM 1101 routinely find that blown-in fiberglass was installed to the correct depth at the hatch but thins out dramatically over exterior walls and can lights - a speed-cut common when crews were racing to keep up with New Braunfels’s building pace - leaving those homes with effective R-values well below label in exactly the spots that drive summer cooling bills highest.

Our Main New Braunfels Services

Most calls we field from New Braunfels homeowners start with attic heat gain or uneven room temperatures, but the root cause almost always traces back to how the original builder treated the thermal boundary. These three services address the problems we see most often in Comal County homes.

Attic Insulation in New Braunfels

Attic insulation in New Braunfels means dealing with attics that hit 140°F in July and dropped below freezing during Uri, often in homes where the original R-30 fiberglass has settled to R-22 or lower. We start every attic job with a blower-door test to measure how much conditioned air is escaping through the ceiling plane, then seal before we insulate. Most attic retrofits in Veramendi and Elm Creek run $2,200-$4,800 depending on square footage and whether we’re adding radiant barrier decking. Attic Insulation in New Braunfels covers our full process, materials from Owens Corning and Johns Manville, and what the documented photo record includes.

Spray Foam Insulation in New Braunfels

Spray foam insulation in New Braunfels makes sense for homeowners who want to convert a vented attic into conditioned space or seal the envelope of a 1970s ranch with no existing wall insulation. Open-cell foam at 3.5 inches gives R-13 in walls and allows vapor permeability, while closed-cell at 2 inches hits R-14 and acts as its own vapor barrier - critical in river-corridor homes with higher ambient humidity. We source from Icynene and Demilec, never proprietary products, and publish before-and-after blower-door numbers on every job. Spray Foam Insulation in New Braunfels breaks down where foam pays back fastest in this market.

Blown-In Insulation in New Braunfels

Blown-in insulation in New Braunfels is the workhorse fix for post-2010 homes with thinned fiberglass over exterior walls and can lights - the speed-cut pattern we document on nearly every inspection along FM 306. We blow cellulose from GreenFiber or fiberglass from Knauf to uniform depth, marked with depth strips at multiple attic locations so you can verify coverage. Every job includes air sealing of top plates and penetrations first; we don’t blow over leaks. Blown-In Insulation in New Braunfels shows pricing by attic square footage and what the written scope specifies.

Crawl Space Encapsulation & Vapor Barrier in New Braunfels

Crawl space encapsulation and vapor barrier work in New Braunfels addresses a specific regional problem: the humid Gulf air that climbs the Balcones Escarpment meets the cooler temperatures of shaded, vented crawl spaces, producing condensation that wets floor joists and breeds mold in homes from Hunter’s Crossing to historic Gruene. Unlike drier markets to the west, New Braunfels crawl spaces need active moisture control, not just passive ventilation, and the 2021 freeze proved how vulnerable uninsulated plumbing in vented crawls can be when Arctic air funnels through the same corridor. Crawl Space Encapsulation & Vapor Barrier details our full protocol, but here’s how we handle the most common New Braunfels conditions.

Crawl Space Vapor Barrier

Signs you need it

White or black mold on floor joists, musty odors rising through vents, or fiberglass batts hanging wet and drooping from the subfloor indicate the ground moisture is evaporating directly into your crawl space air.

What it costs in New Braunfels

A 6-mil to 20-mil vapor barrier installed across the entire crawl floor typically runs $1,200-$2,800 for homes under 2,000 square feet, with thicker mil ratings and sealed seams adding $400-$800.

How we do it

We remove debris, grade the crawl floor for drainage, lay overlapping polyethylene sheets with sealed seams and mechanical fastening at walls and piers, then tape all penetrations before photographing the completed barrier for your record.

Crawl Space Encapsulation

Signs you need it

Standing water after rain, rusted HVAC ducts, or insulation that falls when touched means the crawl space is exchanging air with the outside uncontrolled, and a vapor barrier alone won’t solve it.

What it costs in New Braunfels

Full encapsulation with sealed vapor barrier, insulated foundation walls, closed vents, and a dehumidifier typically ranges $4,500-$8,500 for standard New Braunfels homes, with larger perimeters or active sump pump installations pushing toward the upper end.

How we do it

We seal all vent openings, install rigid foam board on foundation walls, extend the vapor barrier up walls and across piers, add a condensate-pumped dehumidifier set to 55% relative humidity, and deliver before-and-after moisture readings with your photo documentation.

What Crawl Space Encapsulation & Vapor Barrier Costs in New Braunfels

Does encapsulation help with frozen pipes in New Braunfels?

Yes - sealing crawl vents and insulating foundation walls blocks the 20°F wind chill that froze pipes across Comal County during Winter Storm Uri. We document the thermal boundary upgrade with photos and written scope under Haven Standard Clause 1.

How long does crawl space work take?

Most vapor barrier jobs finish in one day; full encapsulation with dehumidifier typically takes two to three days. We text your named technician’s arrival window, and you receive the documented photo record before the crew leaves.

Radiant Barrier Installation in New Braunfels

Radiant barrier installation in New Braunfels targets the specific physics of Hill Country summers: when attic temperatures exceed 130°F for weeks at a time, radiant heat transfer across the attic space drives cooling loads that insulation alone cannot block. New Braunfels’s post-2010 tract homes were built with dark shingles and minimal roof ventilation to cut costs, creating attic conditions that strain HVAC systems from May through October and spike summer electric bills in subdivisions from Elm Creek to Veramendi. Radiant Barrier Installation explains our full product range, but these are the two approaches we deploy most often in Comal County.

Attic Radiant Barrier

Signs you need it

Your upstairs rooms run 8-12°F warmer than downstairs, your AC cycles continuously after 2 PM, or your roof decking is too hot to touch from below indicate radiant heat is overwhelming your existing insulation.

What it costs in New Braunfels

Radiant barrier foil stapled to rafters or laid over attic insulation typically runs $1,400-$3,200 for homes between 1,800 and 3,000 square feet, with attic accessibility and existing insulation depth affecting labor time.

How we do it

We install perforated foil across rafter bottoms or truss chords, maintaining the required 3/4-inch air gap for reflectivity, then verify with an infrared thermometer reading showing surface temperature reduction before we leave.

Radiant Barrier Roof Deck

Signs you need it

New construction or re-roofing projects, or attics where foil would block visual inspection of decking, call for a roof-deck application that doesn’t interfere with future maintenance access.

What it costs in New Braunfels

Radiant barrier decking or spray-applied low-emissivity coating on roof sheathing runs $2,200-$4,800 during new construction or re-roof, with retrofit applications requiring partial decking removal at the higher end.

How we do it

We attach foil-faced OSB during re-roof or spray a ceramic-based radiant coating directly to existing decking, ensuring continuous coverage at valleys and penetrations, then photograph the completed surface for your documented record.

What Radiant Barrier Installation Costs in New Braunfels

Does radiant barrier work with existing insulation?

Yes - radiant barrier complements rather than replaces insulation, reflecting heat that would otherwise saturate your fiberglass or cellulose. In New Braunfels homes with thinned blown fiberglass, we often pair barrier installation with insulation top-up.

Will radiant barrier help my AC last longer?

Reducing attic radiant heat gain cuts the temperature differential your AC fights, which reduces runtime hours and compressor cycling. We measure the before-and-after attic temperature at the same time of day for your record.

Insulation Removal & Replacement in New Braunfels

Insulation removal and replacement in New Braunfels is most often needed in the 1970s-1990s ranch stock and in newer homes where rodents, roof leaks, or builder-grade compression have rendered existing material ineffective. The freeze-thaw cycling and high humidity of the Balcones Escarpment accelerate degradation of fiberglass batts, while the rapid construction pace along FM 1101 left numerous homes with insulation that never performed to label in the first place. Insulation Removal & Replacement covers our full safety protocol, but here’s how we handle the two most common New Braunfels scenarios.

Contaminated Insulation Removal

Signs you need it

Urine stains on ceiling drywall, persistent musty smells after rain, or visible rodent droppings in attic insulation indicate biological contamination that air sealing and new insulation alone cannot fix.

What it costs in New Braunfels

Removal of contaminated attic insulation, HEPA vacuuming of the deck, and application of antimicrobial treatment typically runs $2,400-$4,800 for standard ranch homes, with larger attics or heavy contamination adding $800-$1,500.

How we do it

We erect containment, remove material with sealed bags to exterior disposal, HEPA-vacuum all surfaces, apply EPA-registered antimicrobial, and deliver photos of clean decking before any new insulation is specified or priced.

Insulation Replacement

Signs you need it

Insulation that compresses below joist tops, shows water staining, or has been disturbed by prior trades leaves thermal gaps that blower-door testing will quantify in cubic feet per minute of air loss.

What it costs in New Braunfels

Replacement with new blown fiberglass or cellulose after removal runs $2,200-$4,500 for attics under 2,500 square feet, with spray foam replacement in rooflines or walls quoted separately after air-sealing scope is defined.

How we do it

We air seal the attic floor or roofline first per Haven Standard protocol, install new material to marked and photographed depth, and provide a written scope with blower-door numbers showing the envelope improvement you paid for.

What Insulation Removal & Replacement Costs in New Braunfels

Can you remove insulation with rodents present?

We coordinate with your pest control company or refer trusted partners for active infestation clearance first; we do not handle live trapping. Once cleared, we remove, sanitize, and seal entry points as part of the insulation replacement scope.

Do I need to leave during removal?

Attic removal requires containment and ventilation equipment that makes the home temporarily uncomfortable; most homeowners choose to leave for the day. We text updates and return photos of clean decking before new material goes in.

Attic Air Sealing in New Braunfels

Attic air sealing in New Braunfels is the single most cost-effective envelope upgrade for the city’s post-2010 homes, where speed-built construction left top plates, can lights, and duct boots unsealed despite appearing insulated from the hatch. The 2021 freeze proved how expensive air leakage can be when 20°F wind finds every crack in the ceiling plane, and summer heat gain through the same paths drives cooling costs that radiant barrier and extra insulation cannot fully offset. Attic Air Sealing details our full process, but these are the critical leak paths we seal in New Braunfels homes.

Top Plate & Penetration Sealing

Signs you need it

Dust streaks on attic insulation, visible gaps where interior walls meet the attic floor, or rooms that are dramatically colder in winter and hotter in summer indicate top plate leakage that bypasses your insulation entirely.

What it costs in New Braunfels

Sealing all top plates, wire penetrations, and plumbing stacks in a typical New Braunfels attic runs $1,800-$3,400, with complex rooflines or multiple HVAC zones adding $400-$800 in labor and material.

How we do it

We locate every top plate and penetration with blower-door-guided smoke testing, seal with fire-rated foam and caulk, then re-test to quantify the CFM50 reduction and photograph each sealed location for your record.

Can Light & Duct Boot Sealing

Signs you need it

Can lights that show attic dust on the trim, or rooms where the register blows 85°F air in summer while the thermostat reads 72°F, mean conditioned air is dumping into the attic through unsealed boots and fixtures.

What it costs in New Braunfels

Sealing accessible duct boots and non-IC can lights with fire-rated covers typically adds $800-$1,800 to a top plate job, with inaccessible boots in low-slope attics requiring additional access cuts at extra cost.

How we do it

We install fire-rated enclosures over can lights, mastic-seal all duct boots to drywall or framing, and verify with blower-door and duct-blaster testing that the leakage paths are eliminated before we leave.

What Attic Air Sealing Costs in New Braunfels

How much does air sealing save on bills?

Most New Braunfels homeowners see 15-25% cooling load reduction after proper attic air sealing, with savings concentrated in July and August when leakage-driven heat gain peaks. We document the before-and-after blower-door reading so you can verify the improvement.

Can air sealing be done without adding insulation?

Yes - sealing is a standalone service, and in homes with adequate insulation depth but high air leakage, it often delivers better return than adding more material over unsealed leaks. We assess both paths and quote each separately.

Wall Insulation in New Braunfels

Wall insulation in New Braunfels addresses a gap that builder-grade construction almost always leaves behind: exterior walls with empty cavities or compressed batts that create thermal bypasses around outlets, windows, and corners. The 1970s-1990s ranch stock and even many post-2010 homes along FM 306 were built with no consideration for the Hill Country’s temperature swings, leaving homeowners with cold walls in January and radiant heat gain through siding in August. Wall Insulation covers our full retrofit methods, but these are the two approaches we use most in New Braunfels.

Injection Foam Wall Insulation

Signs you need it

Walls that feel cold to the touch in winter, outlets that draft noticeably, or rooms with exterior walls that never reach thermostat setpoint indicate empty or poorly filled wall cavities.

What it costs in New Braunfels

Injection of slow-rise foam into existing wall cavities from the exterior typically runs $3,200-$6,800 for a 2,000-square-foot home, with stucco or brick cladding requiring more labor than vinyl or fiber-cement siding.

How we do it

We remove siding or drill through mortar joints, inject foam in controlled lifts to avoid bowing, verify fill with thermal imaging, then restore cladding with matched materials and photograph every penetration for your record.

Drill & Fill Wall Insulation

Signs you need it

Homes with no wall insulation, or batts that have settled to half their original thickness, need dense-pack cellulose or fiberglass to restore the intended R-value without full interior demolition.

What it costs in New Braunfels

Dense-pack cellulose or fiberglass blown into drilled wall cavities runs $2,800-$5,400 for standard New Braunfels homes, with two-story construction and brick veneer adding $600-$1,200 for access complexity.

How we do it

We drill 2-inch holes at stud spacing, dense-pack to 3.5 pounds per cubic foot with fill tubes, plug with matching material, and verify complete cavity fill with thermal imaging from the interior before final patching.

What Wall Insulation Costs in New Braunfels

Will wall insulation damage my siding?

We remove and reinstall siding panels or match mortar plug color for brick; the penetrations are 2-inch diameter and fully restored. Your documented photo record shows before, during, and after for every wall section.

How do you know if walls are empty?

We verify with thermal imaging during our initial assessment and can scope cavities with a borescope if needed; we do not quote wall insulation without confirming cavity condition, because empty and partially filled walls require different approaches.

Attic Cleaning & Rodent Proofing in New Braunfels

Attic cleaning and rodent proofing in New Braunfels is often the necessary first step before any insulation work can proceed, particularly in homes near the Guadalupe and Comal River corridors where higher humidity supports both rodent populations and the mold that follows their contamination. The same vented attics that trap summer heat also provide entry points for roof rats and squirrels, especially in the mature tree canopy of older neighborhoods and in newer subdivisions where construction disturbed existing wildlife corridors. Attic Cleaning & Rodent Proofing details our full protocol, but here’s how we handle the two phases most New Braunfels homeowners need.

Attic Sanitizing & Decontamination

Signs you need it

Visible droppings, compressed insulation trails, or a urine odor that intensifies in summer indicate active or recent rodent occupation that has contaminated the attic environment.

What it costs in New Braunfels

Removal of contaminated insulation, HEPA vacuuming, and antimicrobial treatment of attic surfaces typically runs $2,200-$4,500 for standard attics, with heavy accumulation or multiple pest species adding $600-$1,200.

How we do it

We remove all contaminated material in sealed bags, HEPA-vacuum decking and framing, apply EPA-registered sanitizer, and deliver photos of clean surfaces before any air sealing or new insulation is priced or installed.

Rodent Proofing & Exclusion

Signs you need it

Scratching sounds in walls, gnaw marks on soffit vents, or recurring droppings after pest control trapping indicate entry points that trapping alone will not close.

What it costs in New Braunfels

Exclusion sealing of all attic entry points with rodent-proof materials typically runs $1,400-$3,200, with complex rooflines or multiple dormers requiring additional ladder time and material.

How we do it

We inspect every roof penetration, soffit, fascia, and utility entry with the homeowner present when possible, seal with steel mesh and concrete where rodents chew, and photograph every sealed location with a numbered map for future reference.

What Attic Cleaning & Rodent Proofing Costs in New Braunfels

Do you handle live rodents?

We do not trap or remove live animals; we coordinate with your pest control company or refer partners for active infestation clearance. Our work begins after clearance, with exclusion and sanitizing as the permanent fix.

How long before new insulation goes in?

Sanitized attics need 24-48 hours for antimicrobial treatment to fully dry before new insulation is installed; we schedule the insulation crew only after delivering your clean-attic photo confirmation and written scope for the next phase.

Home Energy Audit in New Braunfels

Home energy audit in New Braunfels is where every envelope project we undertake begins, because without measured data we are guessing at solutions in a housing market where builder shortcuts have created problems invisible from the living space. The combination of speed-built construction, Hill Country temperature extremes, and river-corridor humidity means two homes on the same street can have radically different leakage profiles and insulation performance. Home Energy Audit explains our full diagnostic suite, but these are the two tests that reveal what New Braunfels homeowners actually need.

Blower Door Test

Signs you need it

Drafts you cannot locate, rooms that never reach temperature, or energy bills that spike without rate changes indicate envelope leakage that a blower-door test will quantify precisely in CFM50.

What it costs in New Braunfels

A standalone blower-door test with written report runs $350-$650, and is credited toward any air-sealing or insulation work we perform within 90 days of the test date.

How we do it

We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure the airflow required to maintain that pressure difference, then use smoke pencils and infrared cameras to locate the dominant leak paths.

Thermal Imaging Inspection

Signs you need it

Visible temperature variations on walls or ceilings, moisture stains of unknown origin, or suspicion that insulation was installed unevenly call for infrared documentation that shows thermal boundary gaps in real time.

What it costs in New Braunfels

Thermal imaging as part of a full energy audit runs $450-$850, or $250-$450 as a standalone attic and wall scan with annotated images delivered same day.

How we do it

We scan every exterior surface with a FLIR camera during blower-door depressurization to exaggerate leakage patterns, annotate images with temperature readings and location notes, and deliver a PDF report with prioritized repair recommendations.

What Home Energy Audit Costs in New Braunfels

Will an audit tell me if my insulation is adequate?

Yes - thermal imaging reveals insulation gaps, compression, and moisture intrusion that reduce effective R-value below label, while the blower-door test shows whether air leakage is bypassing whatever insulation is present.

How long does the audit take?

Most New Braunfels home energy audits require 2.5 to 4 hours on site, depending on house size and complexity; you receive the written report with annotated thermal images and prioritized recommendations within 48 hours.
