Insulation in Cibolo, TX
Crawl space encapsulation and vapor barrier work in Cibolo typically runs $3,500-$7,500 for most homes, with full encapsulations on larger two-story tract homes reaching the upper end. Because Cibolo’s post-2000 housing stock was built on slab foundations with minimal attention to sub-floor moisture control, homes with crawl spaces - often additions or custom builds in subdivisions like Bentwood Ranch - face humidity issues that slab-built neighbors don’t. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in. Call (830) 243-6352 for a written price before any work starts.
Why Cibolo Homes Are Different
Cibolo is almost entirely 2000s-2020s suburban tract homes in planned subdivisions like Bentwood Ranch and Cibolo Crossing, built rapidly to Texas minimum energy code. The uniformity means whole neighborhoods share the same builder-grade insulation specs and aging timeline simultaneously. In the Guadalupe Valley corridor, attic temperatures exceed 150°F from June through September, compacting blown fiberglass to effective R-19 or less from its original R-30 rating. The February 2021 Winter Storm Uri exposed how this same degraded insulation fails on the cold side, leaving HVAC equipment and pipes vulnerable to sub-10°F air that local construction never historically had to withstand. Homeowners here often assume their “new-ish” home still performs to original specs - a misconception we verify with depth checks that routinely reveal 30-40% insulation deficits.
Our Main Cibolo Services
Most Cibolo homeowners who call us start with attic work or spray foam - here is how we handle each.
Attic Insulation in Cibolo
Attic insulation in Cibolo means addressing settled blown fiberglass in 15-20-year-old tract homes where attic temperatures have compressed original R-30 batts to effective R-19 or lower. We begin with a blower-door test to measure air leakage, seal top plates and penetrations, then install Owens Corning or Johns Manville products to verified depth. Every job closes with a documented photo record and, on applicable work, before-and-after blower-door numbers. Attic Insulation in Cibolo
Spray Foam Insulation in Cibolo
Spray foam insulation in Cibolo addresses the large unconditioned attic volumes typical of two-story homes built during the city’s rapid growth spurts. We use open-cell and closed-cell products from Icynene and Demilec, applied after air sealing is complete - never before. The Haven Standard requires a written price and scope before application begins, and we provide blower-door verification on envelope jobs. Spray Foam Insulation in Cibolo
Blown-In Insulation in Cibolo
Blown-in insulation in Cibolo is the most common retrofit for compacted original fiberglass in subdivisions like Cibolo Crossing. We use GreenFiber cellulose or Knauf fiberglass, installed to specified depth after air sealing the attic floor. A depth check takes 10 minutes and typically reveals the 30-40% performance loss that standard construction here has suffered. Blown-In Insulation in Cibolo

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Cibolo
Most Cibolo homes sit on slab foundations, but crawl spaces do exist - typically in additions, custom builds, or older infill in areas near Cibolo Creek where terrain required raised construction. These crawl spaces suffer from Guadalupe Valley humidity and poor cross-ventilation, creating conditions for mold, wood rot, and sub-floor moisture that slab homes avoid entirely. When we encapsulate a Cibolo crawl space, we start with a written scope and price under Haven Standard Clause 1, then deliver documented photo evidence of every stage. Crawl Space Encapsulation & Vapor Barrier
Crawl Space Vapor Barrier
Signs you need it
Your crawl space needs a vapor barrier if you notice musty odors rising through floor registers, soft or cupping hardwood floors, or visible moisture on joist surfaces during humid months.
What it costs in Cibolo
A 6-mil or thicker polyethylene vapor barrier installed over bare earth in a Cibolo crawl space typically runs $1,200-$2,800 depending on square footage and pier configuration.
How we do it
We clear debris, grade the earth for drainage, seam-seal 10-mil reinforced polyethylene at all overlaps, and mechanically fasten to walls and piers before delivering a documented photo record.
Crawl Space Encapsulation
Signs you need it
Full encapsulation becomes necessary when humidity readings consistently exceed 70% RH, mold appears on joists or insulation, or pest activity has compromised existing fiberglass batts.
What it costs in Cibolo
Complete crawl space encapsulation in Cibolo, including vapor barrier, wall insulation, sealed vents, and dehumidifier, ranges from $4,500-$9,500 for typical residential footprints.
How we do it
We install a reinforced vapor barrier across floor and walls, seal all vent openings, apply closed-cell foam to rim joists, and size a dedicated dehumidifier to maintain 50-55% RH with written performance targets.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Vapor barrier (floor only) | $1,200 - $2,800 |
| Partial encapsulation (barrier + rim joist foam) | $3,500 - $6,000 |
| Full encapsulation with dehumidifier | $4,500 - $9,500 |
How long does crawl space encapsulation take in Cibolo?
Most Cibolo crawl space jobs finish in 1-3 days depending on access constraints and whether existing damaged insulation must be removed first. We provide a written timeline with the price before work begins.
Will encapsulation help with summer humidity in Cibolo?
Yes - Guadalupe Valley humidity regularly pushes crawl spaces above 80% RH in summer, and a sealed, dehumidified envelope maintains 50-55% year-round, protecting sub-floor materials and indoor air quality. Call (830) 243-6352 for a free assessment and written price.
Radiant Barrier Installation in Cibolo
Cibolo’s 150°F+ attic temperatures from June through September make radiant heat gain the dominant cooling load in most homes, particularly in two-story tract houses with large attic volumes built during the 2000s-2010s boom. A radiant barrier reflects infrared radiation rather than absorbing it, reducing ductwork heat gain and attic air temperature independently of insulation R-value - critical in homes where original blown fiberglass has already settled below rated performance. Radiant Barrier Installation
Attic Radiant Barrier
Signs you need it
Your attic needs a radiant barrier if second-story rooms stay uncomfortably warm despite adequate HVAC runtime, or if ductwork in the attic feels hot to the touch during afternoon peak hours.
What it costs in Cibolo
Attic radiant barrier installation in Cibolo typically ranges from $1,800-$3,500 for standard two-story tract homes, depending on attic square footage and accessibility.
How we do it
We staple perforated aluminum foil or install foil-faced OSB across rafter bays after air sealing, ensuring proper attic ventilation paths remain open per manufacturer specifications.
Radiant Barrier Roof Deck
Signs you need it
Roof deck radiant barrier makes sense during re-roofing or new construction, or when attic access is too limited for retrofit installation but the roof deck is exposed.
What it costs in Cibolo
Radiant barrier applied to roof deck sheathing in Cibolo runs $2,200-$4,500 including material and labor, with pricing tied directly to roof pitch and total square footage.
How we do it
We apply reflective foil directly to roof deck plywood or sheathing before shingle installation, or retrofit via limited removal when re-roofing, with written scope and photo documentation.
What Radiant Barrier Installation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic radiant barrier (foil, stapled) | $1,800 - $3,500 |
| Radiant barrier roof deck application | $2,200 - $4,500 |
| Radiant barrier with attic air sealing package | $2,800 - $5,200 |
Does radiant barrier work with settled insulation in Cibolo?
Yes - radiant barrier addresses heat radiation, not conduction, so it complements degraded fiberglass by reducing the temperature that remaining insulation must resist; we still recommend verifying insulation depth.
Can radiant barrier reduce my CPS Energy bill in Cibolo?
Most Cibolo homeowners see 5-15% cooling load reduction after proper radiant barrier installation, with greater impact on homes with ductwork in the attic; call (830) 243-6352 for a written estimate with projected savings.
Insulation Removal & Replacement in Cibolo
Cibolo’s post-2000 tract homes contain builder-grade blown fiberglass that has settled, compacted, and often been compromised by roof leaks, rodent activity, or the 2021 freeze’s ice dam conditions in poorly sealed attics. Removal and replacement is not optional when insulation is contaminated - it is the prerequisite for any new performance gains, and we document the condition we find with photos before touching material. Insulation Removal & Replacement
Contaminated Insulation Removal
Signs you need it
Insulation requires removal when you detect urine odor, visible droppings, water staining, or mold growth on fiberglass surfaces, or when blower-door tests reveal no improvement after air sealing.
What it costs in Cibolo
Contaminated insulation removal in Cibolo typically runs $2,000-$4,500 including bagging, HEPA-contained extraction, and disposal, with pricing scaled to attic square footage and contamination severity.
How we do it
We deploy negative-air HEPA containment, remove material in sealed bags, sanitize substrate with enzyme treatment, and deliver a photo record of the cleaned cavity before any new insulation is specified.
Insulation Replacement
Signs you need it
Replacement follows removal when depth checks show less than 10 inches of fiberglass in a home originally spec’d for R-30, or when thermal imaging reveals cavity voids during energy audit.
What it costs in Cibolo
New insulation replacement in Cibolo after removal runs $2,500-$5,500 for blown fiberglass or cellulose to current depth standards, with spray foam options quoted separately.
How we do it
We air seal the attic floor completely, install baffles at eaves for ventilation, then blow Owens Corning or GreenFiber product to verified depth with ruler photos every 100 square feet.
What Insulation Removal & Replacement Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Contaminated insulation removal only | $2,000 - $4,500 |
| Insulation replacement (blown, after removal) | $2,500 - $5,500 |
| Removal + replacement package | $4,000 - $8,500 |
How do I know if my Cibolo insulation is contaminated?
We inspect visually and with moisture meters during our free assessment; if we find contamination, we show you the photos and provide a written removal scope with the replacement price before any work begins.
Can you remove insulation the same day you quote in Cibolo?
Same-day removal is possible for urgent cases like active roof leaks, but most jobs schedule within 48-72 hours so we can deliver the written price and scope first - Haven Standard requires both before tools touch your home.
Attic Air Sealing in Cibolo
Cibolo’s uniform tract construction means identical air leakage pathways repeat across neighborhoods: unsealed top plates where drywall meets framing, can light penetrations, and duct boots pulling conditioned air into 150°F attics every summer. Attic air sealing is the hard prerequisite we never skip - under Envelope’s protocol, insulation never goes in over an unsealed attic floor, and we prove the result with before-and-after blower-door numbers. Attic Air Sealing
Top Plate & Penetration Sealing
Signs you need it
Your top plates need sealing if blower-door tests show excessive leakage at the attic floor perimeter, or if you feel drafts at exterior wall outlets and switches during winter cold snaps.
What it costs in Cibolo
Top plate and penetration sealing in Cibolo typically ranges from $1,500-$3,200 for standard two-story homes, depending on linear feet of wall top plate and number of penetrations.
How we do it
We access top plates by moving insulation aside, apply fire-rated caulk or foam at all plate gaps, seal wire and pipe penetrations, then replace insulation with photo documentation of sealed locations.
Can Light & Duct Boot Sealing
Signs you need it
Can lights and duct boots leak when you see dust streaking around ceiling fixtures, feel conditioned air loss at HVAC registers, or measure high summer humidity in rooms below the attic.
What it costs in Cibolo
Can light sealing with fire-rated covers and duct boot mastic application in Cibolo runs $800-$2,400 depending on fixture count and duct configuration.
How we do it
We install pre-fabricated fire-rated enclosures over IC and non-IC cans, seal with fire-stop caulk, and apply mastic - not tape - to all duct boot connections with photo record of each location.
What Attic Air Sealing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Top plate & penetration sealing | $1,500 - $3,200 |
| Can light & duct boot sealing | $800 - $2,400 |
| Complete attic air sealing package | $2,500 - $5,000 |
What blower-door improvement should I expect in Cibolo?
Most Cibolo homes we seal show 20-40% leakage reduction - a typical pre-sealing reading of 4,000 CFM50 drops to 2,400-3,200 CFM50 - and we provide the before-and-after numbers in writing with your photo record.
Is attic air sealing required before adding insulation in Cibolo?
It is required by our protocol - we will not blow insulation over an unsealed attic floor because new insulation simply hides leaks without fixing them; the Haven Standard mandates sealing first, then insulating, in that order. Call (830) 243-6352 for a written scope.
Wall Insulation in Cibolo
Cibolo’s 2000s-2010s tract homes were built with minimal wall insulation - often R-13 fiberglass batts in 2×4 walls with incomplete cavity fill and no attention to thermal bridging at studs. Retrofitting wall insulation in these homes requires specialized techniques that don’t require interior demolition, making it viable for homeowners who want envelope improvement without the disruption of a full gut renovation. Wall Insulation
Injection Foam Wall Insulation
Signs you need it
Injection foam makes sense when exterior walls feel hot to the touch in summer, rooms have significant temperature variation from center to perimeter, or original R-13 batts have settled or degraded.
What it costs in Cibolo
Injection foam wall insulation in Cibolo typically runs $3,500-$7,000 for a standard two-story home, priced by exterior wall square footage and cavity depth.
How we do it
We drill 2-inch holes through exterior siding or interior drywall at stud-bay spacing, inject slow-rise foam to verified fill, then plug and match finish with photo documentation of each bay location.
Drill & Fill Wall Insulation
Signs you need it
Drill-and-fill with dense-pack cellulose suits homes with empty or poorly filled stud cavities, particularly where original batts were compressed during fast construction or removed for electrical work.
What it costs in Cibolo
Dense-pack cellulose drill-and-fill in Cibolo ranges from $2,800-$5,500 for typical residential wall footage, with pricing tied to cavity count and access difficulty.
How we do it
We drill access holes, dense-pack GreenFiber cellulose to 3.5 pounds per cubic foot using specialized hose equipment, verify fill with thermal imaging, then patch and finish all penetrations.
What Wall Insulation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Injection foam (exterior walls) | $3,500 - $7,000 |
| Dense-pack cellulose drill & fill | $2,800 - $5,500 |
| Exterior wall insulation with air sealing | $4,500 - $8,500 |
Can you insulate walls without removing drywall in Cibolo?
Yes - injection foam and dense-pack cellulose both install through small drilled holes that we patch and match; interior demolition is only necessary for complete gut renovations or severe moisture damage repair.
Does wall insulation help with Cibolo’s summer heat?
Upgrading from settled R-13 to properly filled R-15 or R-21 equivalent reduces conductive heat gain through walls by 30-50%, which matters when Cibolo’s exterior walls bake in 100°F+ ambient for months; call (830) 243-6352 for a written assessment.
Attic Cleaning & Rodent Proofing in Cibolo
Cibolo’s rapid suburban development displaced wildlife populations that now exploit the consistent construction gaps in 2000s-era tract homes - unsealed eave returns, missing baffles, and penetrations left for future cable runs that became rodent highways. Attic cleaning and rodent proofing is restoration work, not maintenance, and we document the contamination we find with photos before proposing any cleaning scope or proofing plan. Attic Cleaning & Rodent Proofing
Attic Sanitizing & Decontamination
Signs you need it
Sanitizing is necessary when you detect ammonia odor from urine, see droppings or nesting material, or find stained insulation that indicates active or recent rodent occupation.
What it costs in Cibolo
Attic sanitizing and decontamination in Cibolo typically runs $1,800-$4,000 including HEPA vacuuming, enzyme treatment, and odor neutralization, scaled to attic size and contamination level.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzymatic sanitizer to break down organic residue, and run ozone or hydroxyl treatment before delivering a photo-verified clean attic.
Rodent Proofing & Exclusion
Signs you need it
Proofing is required when you hear scratching in walls or attic, find entry gaps larger than 1/4 inch at eaves or roof junctions, or see recurring activity despite trapping efforts.
What it costs in Cibolo
Rodent proofing and exclusion in Cibolo ranges from $1,200-$3,500 depending on linear footage of gap sealing, number of vent covers needed, and complexity of roofline access.
How we do it
We inspect with motion-activated cameras if needed, seal all entry points with rodent-proof materials, install vent and chimney covers, and provide a written warranty on exclusion work with photo documentation.
What Attic Cleaning & Rodent Proofing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic sanitizing & decontamination | $1,800 - $4,000 |
| Rodent proofing & exclusion | $1,200 - $3,500 |
| Full attic restoration (cleaning + proofing + re-insulation) | $4,500 - $9,500 |
How do I know if rodents are in my Cibolo attic?
We inspect for droppings, gnaw marks, compressed insulation trails, and entry gaps during our assessment; if activity is suspected but unconfirmed, we can deploy temporary cameras to verify before quoting.
Will insurance cover rodent damage in Cibolo?
Most Texas homeowners policies exclude rodent damage and contamination cleanup, which is why we provide a written price for both proofing and restoration before any work begins - no surprises, and no waiting for adjuster decisions to start.
Home Energy Audit in Cibolo
A home energy audit in Cibolo reveals the specific performance deficits that uniform tract construction hides - identical floor plans with identical leakage pathways, but varying degrees of insulation settlement and air sealing degradation after 15-20 years of thermal cycling. We use the audit as a diagnostic tool, not a sales presentation, and every finding connects to a written scope with a fixed price. Home Energy Audit
Blower Door Test
Signs you need it
A blower-door test is indicated when rooms have uneven temperatures, energy bills spike without rate changes, or you’ve completed insulation work without verifying air leakage reduction.
What it costs in Cibolo
Standalone blower-door testing in Cibolo typically runs $350-$650, or is included at no charge when bundled with a full energy audit or proposed insulation scope.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 leakage, and identify dominant leakage paths with smoke pencils and thermal imaging for photo documentation.
Thermal Imaging Inspection
Signs you need it
Thermal imaging reveals hidden issues when you suspect missing insulation in walls, moisture intrusion from roof leaks, or thermal bridging at framing members that surface temperature checks cannot detect.
What it costs in Cibolo
Thermal imaging inspection in Cibolo ranges from $300-$550 as a standalone service, or is integrated into our full audit package with written findings and annotated images.
How we do it
We scan interior and exterior surfaces with FLIR cameras during controlled temperature differential conditions, mark anomalies on photos, and correlate findings with blower-door data to prioritize air sealing targets.
What Home Energy Audit Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Blower door test (standalone) | $350 - $650 |
| Thermal imaging inspection | $300 - $550 |
| Full home energy audit (all diagnostics) | $450 - $850 |
What does a Cibolo energy audit include?
Our full audit includes blower-door test, thermal imaging, insulation depth verification, duct leakage assessment, and a written report with prioritized scopes and fixed prices for any recommended work - no open-ended recommendations.
Can I use audit results for CPS Energy rebates in Cibolo?
