Insulation in Boerne, TX
Crawl space encapsulation and vapor barrier work in Boerne typically runs $2,800-$6,500 for most homes, with full encapsulations on larger Hill Country properties reaching the upper end. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in - every job starts with a written price and ends with documented blower-door numbers where applicable. If your Boerne home has a crawl space over the Edwards Plateau limestone, moisture and seasonal temperature swings are working against your floor system year-round. Call (830) 529-7780 for a free estimate with upfront pricing.
Why Boerne Homes Are Different
Boerne sits at roughly 1,400 feet on the Edwards Plateau escarpment, which makes it measurably cooler than San Antonio but also exposes it to harder freeze events and larger daily temperature swings. The dominant housing stock is 2000s-2020s production homes in master-planned communities like Esperanza, built to minimum Texas energy code standards that never accounted for Hill Country extremes - the same homes that underperformed badly during Winter Storm Uri in February 2021.
These slab-on-grade homes over limestone frequently have crawl spaces or pier-and-beam foundations that breathe moisture from the karst geology below. Metal roofs, common in Hill Country-style architecture, supercharge radiant heat gain in attics while the dry conditions cause blown fiberglass to settle below spec. In Esperanza and along the I-10 corridor, we regularly find attic temperatures exceeding 150°F in July and R-values that have dropped 20-30% from the original install. The combination of freeze risk, radiant heat, and moisture intrusion creates a building-envelope challenge that lower-elevation San Antonio suburbs simply don’t face.
Our Main Boerne Services
Most calls from Boerne homeowners center on attic performance and whole-home envelope upgrades. Here are the three services we route to dedicated Boerne pages:
Attic Insulation in Boerne
Attic insulation in Boerne means addressing the radiant heat load from metal roofs and the settling of builder-grade blown fiberglass in dry Hill Country conditions. We start with a blower-door test to measure air leakage, seal all top plates and penetrations, then install to the corrected R-value. Every job gets before-and-after pressurization readings and a Documented Photo Record. Attic Insulation in Boerne

Spray Foam Insulation in Boerne
Spray foam insulation in Boerne is our highest-impact upgrade for homes with metal roofs and large attic temperature swings. We specify open-cell or closed-cell foam from Demilec or Icynene based on whether the roof deck needs moisture management or the crawl space needs a vapor barrier. The air-sealing performance of spray foam is measured and documented with blower-door testing on every job. Spray Foam Insulation in Boerne

Blown-In Insulation in Boerne
Blown-in insulation in Boerne is often a removal-and-replace job rather than a simple top-off, because settled fiberglass in dry conditions rarely meets current R-value targets. We use Owens Corning or Johns Manville loose-fill, installed after air sealing is complete, with depth markers and density checks. The result is verified with thermal imaging and documented in your photo record. Blown-In Insulation in Boerne

Crawl Space Encapsulation & Vapor Barrier in Boerne

Crawl space encapsulation and vapor barrier work in Boerne addresses the moisture that rises through the fractured Edwards Plateau limestone beneath homes, especially in pier-and-beam construction common in older neighborhoods near Main Street and in some newer builds with walk-out basements. The Hill Country’s wet winters and hard freezes create condensation cycles that destroy floor joists and insulation from below - we’ve pulled saturated fiberglass batts from Boerne crawl spaces that were installed dry just three years prior. Crawl Space Encapsulation & Vapor Barrier is our systematic response to this geology.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or floor joists with dark staining.
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 for homes under 2,500 square feet.
How we do it
We grade the earth, seam-seal a reinforced polyethylene membrane to the walls and piers, and seal all penetrations with compatible tape before any insulation goes in.
Crawl Space Encapsulation
Signs you need it
Your HVAC ducts run through the crawl space and sweat in summer, or you smell mustiness in the living space during humid periods.
What it costs in Boerne
Full encapsulation with sealed vapor barrier, insulated walls, and conditioned air supply in Boerne generally ranges from $5,500-$8,500 for typical homes.
How we do it
We install a complete sealed envelope - vapor barrier, rigid foam wall insulation, sealed rim joists, and a dehumidifier if needed - then verify with relative humidity monitoring.
What Crawl Space Encapsulation & Vapor Barrier Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Vapor barrier (6-20 mil, earth coverage only) | $2,800-$4,200 |
| Partial encapsulation (walls + barrier) | $4,500-$6,500 |
| Full encapsulation with dehumidification | $5,500-$8,500 |
How long does crawl space encapsulation take in Boerne?
Most vapor barrier installs finish in one day; full encapsulations with wall insulation and dehumidifiers take two to three days. We schedule around Boerne’s weather patterns to avoid working in standing water. Call (830) 529-7780 for a written price and timeline.
Will encapsulation help with winter floor temperatures?
Yes - sealed crawl spaces in Boerne typically raise floor temperatures 8-12°F during freeze events by stopping cold air infiltration and duct heat loss. We document the before-and-after with infrared imaging.
Radiant Barrier Installation in Boerne

Radiant barrier installation in Boerne is our most cost-effective response to the metal-roof heat gain that dominates newer subdivisions like Esperanza. A radiant barrier - reflective foil or spray-applied coating - blocks radiant heat transfer from roof decking to attic floor, reducing attic temperatures by 20-30°F in peak summer. For homes with existing blown fiberglass that can’t be immediately replaced, this is often the first upgrade we recommend because it works with, not against, the existing insulation. Radiant Barrier Installation
Attic Radiant Barrier
Signs you need it
Your attic exceeds 140°F in summer, your AC runs continuously after 2 PM, or you have a dark or metal roof with R-30 or less insulation.
What it costs in Boerne
Radiant barrier foil installed to attic rafters in Boerne typically costs $1,800-$3,200 for homes between 2,000 and 3,500 square feet.
How we do it
We staple perforated foil to rafter bottoms with proper drape for ventilation channels, seal all edges, and verify attic temperature reduction with thermal imaging.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing or building new in Boerne and want integrated radiant protection without relying on attic floor solutions.
What it costs in Boerne
Spray-applied radiant barrier coating to roof decking during construction or re-roofing runs $2,200-$4,000 depending on roof complexity.
How we do it
We apply a low-emissivity coating to the underside of roof decking before shingles or metal panels go on, creating a permanent radiant block that doesn’t degrade.
What Radiant Barrier Installation Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Foil radiant barrier, attic install | $1,800-$3,200 |
| Spray-applied roof deck coating | $2,200-$4,000 |
| Radiant barrier with attic air sealing | $2,800-$4,800 |
Does radiant barrier work with spray foam?
In Boerne, we typically install radiant barrier in vented attics and skip it when spray foam seals the roof deck directly - the foam itself provides the thermal break. We’ll measure your attic and recommend the higher-ROI path.
How much will my attic temperature drop?
Boerne homes with metal roofs and radiant barrier typically see attic peak temperatures drop from 150°F+ to 115-125°F, measured with our thermal cameras. The change is documented in your photo record.
Insulation Removal & Replacement in Boerne

Insulation removal and replacement in Boerne is most often needed in 2000s-2010s production homes where builder-grade fiberglass has settled below R-value or been compromised by roof leaks, rodent activity, or prior DIY attempts. The dry Hill Country air accelerates settling, and the freeze-thaw cycles of Winter Storm Uri revealed how many Boerne attics had inadequate depth to start with. We remove only what’s necessary, air seal the deck, and install to corrected depth with density-checked blown fill. Insulation Removal & Replacement
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed below the joist tops, has dark staining from roof leaks, or shows rodent trails and droppings throughout.
What it costs in Boerne
Attic insulation removal in Boerne runs $1,500-$2,800 for typical homes, with HEPA containment and bagged disposal included.
How we do it
We set up negative-air containment, remove material with industrial vacuums, dispose off-site, and inspect decking for leaks or mold before any new insulation goes in.
Contaminated Insulation Removal
Signs you need it
Your insulation smells of urine, shows fungal growth, or tested positive for rodent-borne pathogens during a home inspection.
What it costs in Boerne
Contaminated removal with full decontamination in Boerne typically ranges from $2,500-$4,500 depending on area and hazard level.
How we do it
We use PPE and HEPA filtration, apply enzymatic or antimicrobial treatment to decking, and provide clearance documentation before reinstalling insulation.
What Insulation Removal & Replacement Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Standard attic removal (HEPA, disposal) | $1,500-$2,800 |
| Contaminated removal + decontamination | $2,500-$4,500 |
| Removal + replacement with air sealing | $4,200-$7,500 |
Can you remove insulation without replacing it the same day?
We don’t leave Boerne homes uninsulated overnight - removal and replacement are scheduled as a continuous sequence, with air sealing completed between phases. Call (830) 529-7780 to schedule.
Do I need removal or can you just add more?
In Boerne, we add over existing insulation only if it’s dry, uncompressed, and uncontaminated; otherwise removal is required per our Haven Standard scope. We inspect and document the condition before quoting.
Attic Air Sealing in Boerne

Attic air sealing in Boerne is the foundation of every insulation job we do - we will not blow new material over an unsealed attic floor. The pressure differential between conditioned space and vented attic in Hill Country homes drives significant air leakage through top plates, can lights, and duct penetrations, especially during the windy cold fronts that sweep through Kendall County. Our blower-door testing consistently finds Boerne homes losing 30-50% more conditioned air than necessary through these gaps. Attic Air Sealing
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage at the ceiling plane, or you feel drafts at interior wall tops during winter.
What it costs in Boerne
Top plate and penetration sealing for a typical Boerne home runs $1,200-$2,400 as a standalone service, or is included before insulation installation.
How we do it
We access wall top plates from the attic, seal with fire-rated caulk and foam, address all wire and pipe penetrations, and verify with blower-door retest.
Can Light & Duct Boot Sealing
Signs you need it
You have recessed can lights in ceilings below the attic, or visible gaps around duct boots where they penetrate drywall.
What it costs in Boerne
Can light sealing with fire-rated covers and duct boot sealing in Boerne typically adds $800-$1,600 to an air sealing package.
How we do it
We install pre-formed fire-rated enclosures over IC and non-IC cans, seal with high-temp caulk, and mastic-seal all duct boot connections.
What Attic Air Sealing Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Top plate and penetration sealing | $1,200-$2,400 |
| Can light and duct boot sealing | $800-$1,600 |
| Full attic air sealing package | $2,000-$3,500 |
Will air sealing alone lower my bills?
Boerne homes with comprehensive attic air sealing typically see 15-25% HVAC load reduction, verified by before-and-after blower-door numbers we provide in writing. Insulation adds to this, but sealing is the prerequisite.
How do you test if it worked?
We run a blower-door test - pressurizing your home to measure air leakage in CFM50 - before and after sealing, and hand you the two numbers on a written report. Under Haven Standard, the data belongs to you.
Wall Insulation in Boerne

Wall insulation in Boerne addresses the hollow stud cavities common in 1990s-2010s production homes, particularly in subdivisions along I-10 where exterior stone or stucco veneer provides minimal thermal mass. These walls were often insulated with thin fiberglass batts that settled or were poorly fitted, creating cold spots that show clearly on thermal imaging during winter. For homeowners who don’t want to remove siding, injection foam offers a retrofit path with minimal disruption. Wall Insulation
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel cold in winter, you have uneven room temperatures, or thermal imaging shows voids in wall cavities.
What it costs in Boerne
Injection foam wall insulation for a typical 2,000-square-foot Boerne home runs $4,500-$7,500 depending on wall height and access.
How we do it
We drill 2-inch holes through exterior siding or interior drywall, inject slow-rise foam to fill cavities completely, patch, and verify fill with thermal imaging.
Drill & Fill Wall Insulation
Signs you need it
Your older Boerne home near Main Street has no insulation in exterior walls, or prior insulation has collapsed to the bottom of studs.
What it costs in Boerne
Drill and fill with dense-pack cellulose in Boerne typically costs $3,200-$5,800 for homes with accessible stud bays.
How we do it
We drill at stud-bay intervals, blow GreenFiber dense-pack cellulose to 3.5 pounds per cubic foot, seal holes, and confirm density with wall cavity probes.
What Wall Insulation Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Injection foam, exterior walls | $4,500-$7,500 |
| Drill & fill dense-pack cellulose | $3,200-$5,800 |
| Interior wall soundproofing | $2,800-$4,500 |
Will injection foam damage my stucco?
We drill through mortar joints or plan for stucco patch matching; in Boerne’s Hill Country-style homes, we coordinate with local masons when needed for seamless repair. The scope includes patching in your written price.
How much does wall insulation help in summer?
Boerne homes with filled wall cavities typically see exterior wall surface temperatures drop 10-15°F in peak summer, reducing radiant heat gain that overloaded fiberglass couldn’t stop. We document with thermal imaging.
Attic Cleaning & Rodent Proofing in Boerne

Attic cleaning and rodent proofing in Boerne is frequently needed in homes where builder gaps at roof-wall junctions and unsealed soffits provide entry for roof rats and squirrels common to the Hill Country. The same dry conditions that degrade insulation also preserve rodent trails and droppings, creating contamination that standard insulation replacement doesn’t address. We clean, sanitize, and exclude - in that order - with photo documentation at each phase. Attic Cleaning & Rodent Proofing
Attic Cleanout & Sanitizing
Signs you need it
Your attic has visible droppings, nesting material, or urine staining on insulation or decking.
What it costs in Boerne
Attic cleanout with HEPA vacuuming and sanitizing in Boerne runs $1,800-$3,200 for typical contamination levels.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzymatic sanitizer, and provide photo documentation before any new work begins.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find new droppings after prior cleanup, or see gnaw marks on soffit vents or roof returns.
What it costs in Boerne
Rodent proofing with exclusion sealing for a typical Boerne home ranges from $1,200-$2,800 depending on entry point complexity.
How we do it
We inspect with motion-activated cameras if needed, seal all entry points with rodent-proof materials, install vent guards, and guarantee the exclusion for one year.
What Attic Cleaning & Rodent Proofing Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Attic cleanout + sanitizing | $1,800-$3,200 |
| Rodent proofing & exclusion | $1,200-$2,800 |
| Full restoration (cleanout + proofing + insulation) | $4,500-$8,500 |
Do you handle dead rodents in the attic?
Yes - we locate and remove carcasses, treat the area with enzymatic cleaner, and document the source of odor. This is included in our cleanout scope when present. Call (830) 529-7780.
How do you know where they’re getting in?
We inspect roof-soffit junctions, pipe penetrations, and vent screens with photo documentation; in Boerne’s newer subdivisions, we frequently find unsealed builder gaps at fascia boards that rats exploit. Every entry point is noted in your written report.
Home Energy Audit in Boerne

A home energy audit in Boerne identifies the specific envelope failures costing you money - most commonly air leakage at the attic floor, duct losses in vented crawl spaces, and missing or settled insulation in walls and ceilings. The Hill Country’s temperature extremes mean every deficiency is punished twice: summer heat gain and winter heat loss both drive up HVAC runtime. Our audit provides a prioritized scope with written prices for each recommendation, not a generic checklist. Home Energy Audit
Blower Door Test
Signs you need it
Your energy bills are higher than comparable Boerne homes, or you feel drafts and uneven temperatures despite recent HVAC service.
What it costs in Boerne
A standalone blower-door test with written report in Boerne costs $350-$550; it’s credited toward work if you proceed within 90 days.
How we do it
We install a calibrated fan in an exterior door, depressurize to 50 Pascals, measure leakage in CFM50, and locate leaks with smoke pencils and infrared cameras.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation, moisture intrusion, or duct leaks that aren’t visible to standard inspection.
What it costs in Boerne
Thermal imaging as part of a full audit runs $450-$750; standalone imaging for specific concerns is $300-$450.
How we do it
We scan walls, ceilings, and ductwork with FLIR cameras during normal HVAC operation and during blower-door depressurization to reveal hidden thermal bypasses.
What Home Energy Audit Costs in Boerne
| Item | Typical range in Boerne |
|---|---|
| Blower-door test with written report | $350-$550 |
| Full audit (blower door + thermal + inspection) | $450-$750 |
| Audit credit applied to work | 100% within 90 days |
How long does an energy audit take?
A full Boerne home energy audit takes 3-4 hours for a typical home; you receive the written report with prioritized recommendations and prices within 48 hours. Scheduling is coordinated from our San Antonio office with local crews.
Will the audit tell me if I need new insulation?
Yes - we measure existing R-values, identify settled or missing insulation, and specify exactly what depth and type is needed where, with a written price for each location before any work starts.

What Boerne Customers Say
"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."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R."They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N.
