Insulation in Boerne, TX
Crawl space encapsulation and vapor barrier work in Boerne runs $2,800-$6,500 for most homes, with full encapsulations on larger Hill Country custom homes 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. Our dispatch and scheduling are coordinated from our San Antonio office, but crews serve Boerne locally every day. Call (737) 227-6219 for a written price before any work starts.
Why Boerne Homes Are Different
Boerne sits at roughly 1,400 feet on the Edwards Plateau - significantly higher than San Antonio 30 miles south - exposing homes to far more annual freeze events and violent “Blue Norther” cold fronts that can drop temperatures 30-40°F in hours. This creates a true dual-season thermal demand that separates Boerne’s insulation needs from lower-elevation suburbs.
The housing stock tells the same story. Thousands of Hill Country-style custom and semi-custom homes built since the 2000s, concentrated around developments like Cordillera Ranch, feature complex hip rooflines, vaulted ceilings, and stone or stucco exteriors that create difficult access and air-sealing challenges. A smaller older layer of 1960s-1980s downtown-adjacent homes retains original fiberglass batts that have settled and lost R-value, often with zero air-sealing at top plates. The shallow limestone karst makes slab-on-grade construction nearly universal, so the entire insulation performance equation concentrates in the attic and wall cavities - making undersized or poorly installed attic insulation disproportionately costly here.
The cleared limestone terrain of newer subdivisions offers minimal tree canopy to shade rooftops, driving attic temperatures past 155°F in summer. The same thermal bypass that bleeds conditioned air in August allows pipe-freezing cold infiltration during winter fronts that San Antonio-calibrated builders often underestimate.
Our Main Boerne Services
Most Boerne homeowners who call us start with attic work or spray foam. Here’s what those jobs look like locally.
Attic Insulation in Boerne
Attic insulation in Boerne means dealing with complex hip rooflines and vaulted ceilings that trap heat at multiple elevations. We see a lot of original R-30 batts in Cordillera Ranch-area homes that were adequate on paper in 2008 but have settled to R-22 or lower. Our crews measure actual depth, check for thermal bypass at top plates and can lights, and air-seal before adding any new material. Every job gets a written price before work starts and a Documented Photo Record when we leave. Attic Insulation in Boerne details our full process.
Spray Foam Insulation in Boerne
Spray foam insulation in Boerne works best in homes where vaulted ceilings or knee walls make conventional batts impossible to install properly. We use open-cell foam for most attic applications and closed-cell for rim joists and crawl spaces where moisture control matters. The Haven Standard requires a written price and written scope before anyone lifts a tool, and we publish before-and-after blower-door numbers on every applicable job. Spray Foam Insulation in Boerne covers material options and typical timelines.
Blown-In Insulation in Boerne
Blown-in insulation in Boerne is our most common retrofit for settled fiberglass in older downtown-adjacent homes and for topping off under-insulated attics in 2000s-era construction. We blow Owens Corning or Johns Manville fiberglass, or GreenFiber cellulose, over a sealed attic floor - never over an unsealed one. The blower-door test, a pressurization reading that shows in one number how much air your building envelope is losing, tells us whether the air sealing was done right. Blown-In Insulation in Boerne has full specs.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Boerne
True crawl spaces are rare in Boerne - blasting through the Edwards Plateau limestone is prohibitively expensive, so most homes are slab-on-grade. Where they do exist, typically in older downtown-adjacent homes or custom builds with walk-out basements on sloped lots, they’re moisture traps. Crawl Space Encapsulation & Vapor Barrier is the service we use to seal them against the Hill Country’s humidity swings and hard-freeze events.
Crawl Space Vapor Barrier
Signs you need it
Standing water after rain, white mineral deposits on block walls, or a musty smell that enters the living space through floor gaps.
What it costs in Boerne
A 6-mil to 20-mil vapor barrier installed over bare earth in a Boerne crawl space typically runs $2,800-$4,200.
How we do it
We remove debris, grade the floor, seam-seal the barrier with tape, and mechanically fasten it to walls - then document with photos.
Crawl Space Encapsulation
Signs you need it
Rotting floor joists, insulation falling from the subfloor, or mold visible on structural members.
What it costs in Boerne
Full encapsulation with sealed vapor barrier, dehumidifier, and insulated walls in a Boerne crawl space ranges $4,500-$6,500.
How we do it
We install a multi-layer sealed barrier, add a dedicated dehumidifier with condensate pump, and seal all vents - then provide before-and-after humidity readings.
What Crawl Space Encapsulation & Vapor Barrier Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Vapor barrier (6-20 mil, earth cover only) | $2,800 - $4,200 |
| Full encapsulation with dehumidifier | $4,500 - $6,500 |
| Crawl space insulation (rigid foam board) | $1,800 - $3,200 |
How long does crawl space encapsulation take in Boerne?
Most vapor barrier jobs finish in one day; full encapsulations with dehumidifier installation take two to three days. We schedule around Boerne’s weather, since exterior access matters for material staging.
Will encapsulation stop my floors from feeling cold in winter?
Yes - sealing the crawl space and adding perimeter insulation stops the 40-50°F air from contacting your subfloor during Blue Norther events. Call (737) 227-6219 for an exact quote; estimates are free.
Radiant Barrier Installation in Boerne
Radiant barrier installation in Boerne addresses a specific Hill Country problem: attic temperatures regularly exceed 155°F on cleared limestone lots with no tree canopy, and that radiant heat transfers directly into ductwork and living spaces below. In Cordillera Ranch and similar developments, we’ve measured attic sheathing at 160°F+ in July - temperatures that overwhelm R-value alone. Radiant Barrier Installation reflects that heat back toward the roof deck rather than letting it load your ceiling.
Attic Radiant Barrier
Signs you need it
Your AC runs continuously after 2 p.m., upstairs rooms stay 8-12°F hotter than downstairs, or your ductwork in the attic feels hot to the touch.
What it costs in Boerne
Radiant barrier foil stapled to rafters or laid over attic insulation in a typical Boerne home runs $1,200-$2,400.
How we do it
We install perforated foil across rafter bays or drape it over existing insulation, maintaining ventilation gaps - then photograph the coverage.
Radiant Barrier Roof Deck
Signs you need it
New construction or re-roofing where you want the barrier integrated at the sheathing level for maximum effectiveness.
What it costs in Boerne
Radiant barrier roof deck installation during construction or re-roofing in Boerne typically costs $1,800-$3,200.
How we do it
We attach foil-faced sheathing or spray-applied low-emissivity coating directly to the roof deck before shingles go on.
What Radiant Barrier Installation Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Attic radiant barrier (foil, existing home) | $1,200 - $2,400 |
| Radiant barrier roof deck (new construction/re-roof) | $1,800 - $3,200 |
| Radiant barrier with attic air sealing package | $2,400 - $4,000 |
Does radiant barrier work with spray foam?
Yes - we install radiant barrier on the roof deck, then spray foam against it in unvented attic assemblies common in newer Boerne custom homes. The combination blocks radiant heat and stops air leakage.
Will radiant barrier help in winter too?
It helps marginally by reducing radiant heat loss from the attic, but the bigger winter gain in Boerne comes from air sealing first. Call (737) 227-6219 and we’ll show you the blower-door numbers.
Insulation Removal & Replacement in Boerne
Insulation removal and replacement in Boerne is common in two situations: downtown-adjacent homes from the 1960s-1980s with original fiberglass batts that have settled and compressed, and newer custom homes where rodents or moisture have compromised attic insulation. The Hill Country’s temperature swings accelerate degradation - fiberglass that loses 30% of its loft loses 30% of its R-value. Insulation Removal & Replacement starts with a written scope and ends with a clean, documented attic.
Attic Insulation Removal
Signs you need it
Insulation is compressed below the joist tops, has dark staining from past leaks, or shows rodent trails and droppings throughout.
What it costs in Boerne
Removing old fiberglass or cellulose from a typical Boerne attic runs $1,500-$2,800, with disposal included.
How we do it
We use commercial vacuums with HEPA filtration, bag the material on-site, and haul it - then photograph the clean deck.
Contaminated Insulation Removal
Signs you need it
Visible mold on insulation fibers, a history of raccoon or bat infestation, or a persistent odor that survives surface cleaning.
What it costs in Boerne
Contaminated insulation removal with sanitizing in Boerne typically costs $2,200-$4,000 depending on square footage and contamination level.
How we do it
We remove all compromised material, apply antimicrobial treatment to the deck, and verify with moisture readings before new insulation goes in.
What Insulation Removal & Replacement Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Standard attic insulation removal | $1,500 - $2,800 |
| Contaminated insulation removal + sanitizing | $2,200 - $4,000 |
| Removal + replacement with new blown-in | $3,500 - $6,000 |
Can you remove insulation with asbestos?
We do not handle asbestos-containing vermiculite; we refer those jobs to licensed abatement contractors and resume work after clearance. If you suspect asbestos, tell us when you call.
How long does removal and replacement take?
Most removals finish in one day; removal plus replacement takes two days. We coordinate with your schedule and provide the Documented Photo Record at completion. Call (737) 227-6219 for a written price.
Attic Air Sealing in Boerne
Attic air sealing in Boerne is the single most cost-effective envelope improvement we perform, because the same thermal bypass that bleeds AC in August allows pipe-freezing cold infiltration during Blue Norther fronts. San Antonio-calibrated builders often underestimate this dual-season demand. Attic Air Sealing is always completed before any insulation is added - it’s Haven Standard, not optional.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks on insulation around wall tops, visible gaps where drywall meets the top plate, or cobwebs indicating air movement at penetrations.
What it costs in Boerne
Sealing top plates, wire penetrations, and plumbing stacks in a typical Boerne attic runs $800-$1,500.
How we do it
We use two-part foam and acrylic caulk to seal every gap larger than 1/16 inch, then verify with a blower-door test.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that leak attic air into living space, or duct boots pulling 130°F attic air into your HVAC system.
What it costs in Boerne
Sealing can lights with rated covers and mastic-sealing duct boots in Boerne typically costs $600-$1,200.
How we do it
We install fire-rated airtight covers over IC and non-IC cans, then seal duct boots with mastic and mesh - photograph everything.
What Attic Air Sealing Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Top plate & penetration sealing | $800 - $1,500 |
| Can light & duct boot sealing | $600 - $1,200 |
| Full attic air sealing (comprehensive) | $1,400 - $2,600 |
Do I need air sealing if I’m adding new insulation?
Yes - we will not blow insulation over an unsealed attic floor. New insulation over a leaky ceiling performs like a sweater with holes in it. The Haven Standard requires sealing first.
How much does air sealing actually save?
We’ve measured 25-40% reduction in blower-door CFM50 on Boerne homes after comprehensive attic sealing. Call (737) 227-6219 and we’ll show you before-and-after numbers from comparable homes.
Wall Insulation in Boerne
Wall insulation in Boerne addresses a gap common in 2000s-era custom homes: builders often insulated attics to code minimum but left walls with R-11 batts or missed cavities entirely behind complex stone and stucco exteriors. The stone veneer creates a thermal bridge, and the stucco application can compress or displace batts. Wall Insulation fills these gaps without tearing off finishes.
Injection Foam Wall Insulation
Signs you need it
Walls that feel cold in winter, rooms with exterior walls that are 5-10°F cooler than interior rooms, or outlets that draft cold air.
What it costs in Boerne
Injection foam insulation for exterior walls in a typical Boerne home runs $3,500-$6,500 depending on wall area and cavity condition.
How we do it
We drill 5/8-inch holes between studs, inject slow-rise foam that fills without bowing drywall, then patch and texture-match.
Drill & Fill Wall Insulation
Signs you need it
Empty wall cavities discovered during remodeling, or original R-11 batts that have settled to half their thickness in two-story walls.
What it costs in Boerne
Drill-and-fill with dense-pack cellulose in Boerne walls typically costs $2,800-$5,000 for a complete home.
How we do it
We remove a row of siding or drill through exterior sheathing, blow cellulose to 3.5 pounds per cubic foot density, and seal penetrations.
What Wall Insulation Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Injection foam (exterior walls) | $3,500 - $6,500 |
| Drill & fill dense-pack cellulose | $2,800 - $5,000 |
| Interior wall soundproofing (per room) | $1,200 - $2,400 |
Will injection foam damage my drywall?
No - we use slow-rise formulations at controlled pressure, and we’ve completed hundreds of Boerne injections without drywall distortion. The Haven Standard includes a 365-Day Done Right Promise if any issue arises.
Can you insulate walls without removing siding?
Sometimes - if the home has removable siding panels or if we access from inside during a renovation. For stucco exteriors common in Cordillera Ranch, we typically drill through the stucco and patch. Call (737) 227-6219 for a specific assessment.
Attic Cleaning & Rodent Proofing in Boerne
Attic cleaning and rodent proofing in Boerne is a growth service because the Hill Country’s oak-juniper woodland interface - even in cleared subdivisions - supports healthy rodent populations that exploit construction gaps in complex rooflines. We’ve found entry points in Boerne homes where hip roof valleys meet stone veneer, gaps that simpler gable-roof tract homes rarely develop. Attic Cleaning & Rodent Proofing removes contamination and stops re-entry.
Attic Sanitizing & Decontamination
Signs you need it
Visible rodent droppings, urine staining on insulation or decking, or a sharp ammonia smell detectable at the attic hatch.
What it costs in Boerne
Attic sanitizing and decontamination in Boerne typically runs $1,800-$3,200 depending on contamination extent and attic square footage.
How we do it
We remove soiled insulation, HEPA-vacuum the deck, apply enzymatic cleaner, and verify with ATP swab testing - then document.
Rodent Proofing & Exclusion
Signs you need it
Scratching noises in walls at night, gnaw marks around roof penetrations, or recurring rodent activity after prior trapping.
What it costs in Boerne
Rodent proofing and exclusion for a typical Boerne home ranges $1,200-$2,400, with one-year re-entry guarantee.
How we do it
We seal all entry points 1/4 inch or larger with steel mesh and concrete, install ridge vent guards, and photograph every sealed location.
What Attic Cleaning & Rodent Proofing Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Attic sanitizing & decontamination | $1,800 - $3,200 |
| Rodent proofing & exclusion | $1,200 - $2,400 |
| Full attic restoration (cleanout + proofing + new insulation) | $4,500 - $8,000 |
How do I know if rodents are in my attic now?
Listen for scratching after dark, check for droppings near the hatch, and look for gnawed PVC vent caps on the roof. We provide a free inspection with photo documentation.
Will rodents come back after you seal?
Our exclusion work carries a one-year re-entry guarantee; if they find a new path, we return and seal it at no charge. Call (737) 227-6219 to schedule.
Home Energy Audit in Boerne
A home energy audit in Boerne gives you documented evidence of where your home loses conditioned air, prioritized by cost-effectiveness. Because Boerne’s dual-season demand means the same leaks hurt you in both summer and winter, the audit payback here is typically faster than in milder climates. Home Energy Audit includes blower-door testing, thermal imaging, and a written scope with prioritized recommendations.
Blower Door Test
Signs you need it
You suspect air leaks but don’t know their magnitude, or you want verified proof of improvement after envelope work.
What it costs in Boerne
A standalone blower-door test in Boerne runs $350-$500; it’s included free with any audit that leads to contracted work.
How we do it
We depressurize the home to 50 Pascals, measure CFM50 leakage, and use a smoke pencil to locate dominant leak paths - then photograph findings.
Thermal Imaging Inspection
Signs you need it
Uneven temperatures across rooms, suspected missing insulation behind finished walls, or ice dam history on complex rooflines.
What it costs in Boerne
Thermal imaging as part of a comprehensive energy audit in Boerne typically costs $250-$400 when purchased separately.
How we do it
We scan with FLIR cameras during blower-door depressurization to make thermal bypasses visible, then mark findings on floor plans.
What Home Energy Audit Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Comprehensive home energy audit | $450 - $750 |
| Blower-door test (standalone) | $350 - $500 |
| Thermal imaging inspection | $250 - $400 |
What does the audit report include?
A written scope with blower-door CFM50, thermal images with annotations, prioritized air-sealing and insulation recommendations, and estimated ranges for each improvement. You own the report regardless of whether you hire us.
Can I use the audit for utility rebates?
Yes - CPS Energy and some Hill Country co-ops accept third-party blower-door documentation for rebate programs. We format reports to their specifications. Call (737) 227-6219 to confirm current program requirements.
