Insulation in Cibolo, TX
Crawl space encapsulation and vapor barrier installation in Cibolo typically runs $3,500-$7,500 for a full encapsulation, while radiant barrier installation in attics runs $1,200-$2,800 depending on roof complexity. Most Cibolo homes built during the 2005-2020 boom were constructed on slab foundations, but the remaining crawl spaces and pier-and-beam additions in older pockets and outlying areas face the same hot-humid Climate Zone 2 conditions that make ground moisture control critical. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite on every job, not an upsell. Call (830) 402-5240 for a written price before any work starts.
Why Cibolo Homes Are Different
Cibolo is one of the fastest-growing cities in Texas, and its housing stock is almost entirely production-built tract homes constructed between roughly 2005 and the present by volume builders who installed the minimum insulation required to pass code - typically R-13 fiberglass batts in 2×4 exterior walls and R-30 blown fiberglass in attics. These homes are now hitting the 10-20 year mark simultaneously, meaning a massive cohort of Cibolo homeowners are discovering at the same time that builder-grade insulation that barely met code on move-in day is now settled, degraded, and losing the battle against Guadalupe County’s 100°F+ summers.
The narrow age band creates unusual consistency in what we find. In The Crossvine and similar master-planned developments, DR Horton and Lennar homes share the same 2×4 framing, the same skipped attic air sealing at top plates, and the same unsealed can lights. The February 2021 Winter Storm Uri exposed how poorly these production envelopes perform in extreme cold, creating dual-season demand that purely cooling-focused markets farther south don’t see. When we dispatch from our San Antonio office, crews arrive knowing exactly which shortcuts the local builders took.
Our Main Cibolo Services
Most Cibolo homeowners who call us start with attic work or spray foam; here is what those jobs involve locally.
Attic Insulation in Cibolo
Attic insulation in Cibolo means addressing attics that were blown with R-30 fiberglass a decade ago and have since settled to R-19 or lower, while the attic floor beneath was never sealed. We pull back existing material, seal top plates and penetrations with foam and caulk, then reinstall to R-38 or R-49 with Owens Corning or Johns Manville products. Every attic job includes a blower-door test when accessible, with before-and-after readings published in your documented record. Attic Insulation in Cibolo covers the full scope.
Spray Foam Insulation in Cibolo
Spray foam insulation in Cibolo makes sense for homeowners who want to air seal and insulate in one step, particularly in bonus rooms over garages or in homes where HVAC ducts run through vented attics. We use open-cell foam at the roof deck to create conditioned attics, or closed-cell foam in crawl spaces and rim joists where moisture resistance matters. Demilec and Icynene products are specified by application, never pushed as a default. Spray Foam Insulation in Cibolo has full details.
Blown-In Insulation in Cibolo
Blown-in insulation in Cibolo is the most common retrofit for settled attics, but we won’t blow new material over an unsealed floor. Our crews use GreenFiber cellulose or Owens Corning fiberglass, depending on your priority - cellulose for higher density and sound dampening, fiberglass for lighter weight on older ceiling drywall. The blower-door test after sealing shows the actual performance change, not just the added R-value. Blown-In Insulation in Cibolo explains the process.

Crawl Space Encapsulation & Vapor Barrier in Cibolo
Crawl space encapsulation and vapor barrier installation in Cibolo addresses the persistent ground moisture that hot-humid Climate Zone 2 drives into pier-and-beam and raised-slab crawl spaces year-round. While most Cibolo homes are slab-on-grade, the remaining crawl spaces - often in outlying builds and older pockets near Cibolo Creek - face 70%+ relative humidity under the floor that fiberglass batts absorb until they sag and mold. Crawl Space Encapsulation & Vapor Barrier is our primary service for these homes, and every job starts with a written scope and ends with a documented photo record.
Crawl Space Encapsulation
Signs you need it
Your floors feel cold in winter despite the heat running, you smell mustiness from vents or gaps, or your energy bills spike when humidity climbs above 60%.
What it costs in Cibolo
Full crawl space encapsulation in Cibolo typically runs $3,500-$7,500 depending on square footage, pier count, and whether we need to remove degraded existing insulation first.
How we do it
We remove wet or moldy material, install a 12-20 mil reinforced polyethylene vapor barrier sealed at seams and walls, close vents with rigid foam blocks, and add a dehumidifier sized to the space with a condensate pump to exterior.
Crawl Space Vapor Barrier
Signs you need it
You see standing water after rain, plastic sheeting from construction is torn or missing, or your rim joists show dark staining from seasonal moisture wicking.
What it costs in Cibolo
Vapor barrier-only installation in Cibolo runs $1,500-$3,200 for standard crawl spaces under 1,500 square feet, with thicker mil ratings and seam sealing at the higher end.
How we do it
We grade the floor, lay overlapping sheets of reinforced polyethylene, seal all seams with waterproof tape, and mechanically fasten to walls and piers so the barrier stays intact during future access.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Crawl space vapor barrier (standard) | $1,500 - $3,200 |
| Full encapsulation with dehumidifier | $3,500 - $7,500 |
| Insulation removal and replacement add-on | $800 - $2,000 |
How long does crawl space encapsulation take in Cibolo?
Most Cibolo crawl space encapsulations finish in two to three days, with day one for removal and prep, day two for barrier and sealing, and day three for dehumidifier setup and testing. Call (830) 402-5240 for a written price and scheduling - estimates are free.
Will encapsulation stop my floors from feeling cold?
Yes, sealing ground moisture and adding perimeter insulation stops the evaporative cooling that makes floors feel cold even when the thermostat reads 72°F. We verify the result with a post-job inspection and photo record.
Radiant Barrier Installation in Cibolo
Radiant barrier installation in Cibolo targets the attic heat gain that drives cooling costs through July and August, when roof deck temperatures exceed 150°F and radiate downward into living spaces. Production builders in Cibolo’s boom years rarely installed radiant barriers as standard, leaving HVAC systems to fight radiant load with longer run times and shorter equipment life. Radiant Barrier Installation is the most cost-effective retrofit for these unshaded, dark-shingle roofs.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 PM, your AC runs continuously between 2 PM and 7 PM, or your roof shingles are dark and less than five years old with no tree cover.
What it costs in Cibolo
Attic radiant barrier installation in Cibolo typically runs $1,200-$2,800 for single-story homes and $1,800-$3,500 for two-story homes with complex rooflines and limited attic access.
How we do it
We staple perforated foil across rafter bays or lay it over existing attic insulation, depending on roof ventilation strategy, with cuts around penetrations and electrical to maintain fire safety clearance.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the barrier integrated at the deck level, or your attic has spray foam at the roofline and you need radiant control without additional ventilation changes.
What it costs in Cibolo
Radiant barrier roof deck application during reroofing in Cibolo adds $0.75-$1.50 per square foot to the roofing scope, or $2,000-$4,500 as a standalone retrofit with deck access.
How we do it
We apply foil-faced sheathing or liquid-applied radiant coating directly to the roof deck underside, sealed at seams and integrated with ridge venting so attic ventilation still functions.
What Radiant Barrier Installation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic radiant barrier (foil, standard home) | $1,200 - $2,800 |
| Two-story or complex roofline | $1,800 - $3,500 |
| Roof deck application (standalone) | $2,000 - $4,500 |
Does radiant barrier work with blown-in insulation?
Yes, we install radiant barrier first, then blow insulation over the top layer or use a perforated product that allows vapor transmission; the combination blocks radiant heat and slows conductive transfer. Call (830) 402-5240 for a written price on the combined scope.
How much will my cooling bill drop?
Most Cibolo homeowners see 5-15% cooling savings, with the highest returns on homes with dark shingles, minimal shade, and ducts in vented attics; we document pre- and post-installation attic temperatures in your photo record.
Insulation Removal & Replacement in Cibolo
Insulation removal and replacement in Cibolo is increasingly common as the city’s first major housing wave crosses the 15-year mark, with settled fiberglass, rodent contamination, and water damage accumulating in attics that were never designed for access or maintenance. The consistent construction era means we see the same failure patterns across neighborhoods - compressed batts, blown fiberglass settled below joist tops, and unsealed bypasses that rendered whatever R-value remained ineffective. Insulation Removal & Replacement starts with testing, not tearing.
Attic Insulation Removal
Signs you need it
Your attic insulation is below the top of the joists, you find droppings or nesting material, or you’ve had a roof leak that saturated fiberglass batts that won’t dry in Cibolo’s humidity.
What it costs in Cibolo
Attic insulation removal in Cibolo runs $1.00-$2.50 per square foot, or $1,200-$3,000 for a typical 1,800-square-foot footprint, with contaminated material at the higher end requiring HEPA containment.
How we do it
We set up negative air pressure with HEPA filtration, remove material by machine or by hand around obstructions, bag on-site, and dispose off-site before inspecting the deck for leaks or structural issues.
Contaminated Insulation Removal
Signs you need it
You smell ammonia or musk in the attic access, see urine stains on the ceiling drywall below, or have had rodents, bats, or raccoons active in the attic within the past two years.
What it costs in Cibolo
Contaminated insulation removal in Cibolo with full decontamination runs $2,500-$5,500 depending on contamination extent, with rodent proofing and replacement insulation quoted separately in the written scope.
How we do it
We suit in PPE, remove and bag contaminated material under negative pressure, apply enzymatic cleaner to affected decking, and hold replacement until the attic tests clear of active biological hazard.
What Insulation Removal & Replacement Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Standard attic insulation removal | $1,200 - $3,000 |
| Contaminated removal with decontamination | $2,500 - $5,500 |
| Replacement insulation (blown cellulose, R-38) | $1,800 - $3,500 |
Can I stay in the house during removal?
Yes for standard removal, no for contaminated material requiring HEPA containment and negative pressure; we coordinate timing and provide a clear re-entry schedule in the written scope. Call (830) 402-5240 to discuss your specific attic condition.
Do you remove vermiculite insulation?
We do not handle vermiculite - if your Cibolo home was built before 1990 and has granular gray-brown attic insulation, we refer to certified asbestos abatement contractors and resume work after clearance testing.
Attic Air Sealing in Cibolo
Attic air sealing in Cibolo is the single most impactful upgrade for production-built homes from the 2005-2020 boom, because volume builders universally blew insulation over unsealed top plates, wire penetrations, and interior partition walls to pass inspection faster. The result is a thermal bypass network that lets conditioned air escape into the attic year-round, spiking bills in summer and creating the cold drafts Cibolo homeowners noticed during Winter Storm Uri. Attic Air Sealing is never sold as an upsell - it’s prerequisite work on every applicable job.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from outlets on exterior walls, your blower-door test shows excessive air leakage, or infrared imaging reveals cold stripes at ceiling corners on winter mornings.
What it costs in Cibolo
Top plate and penetration sealing in Cibolo runs $800-$2,200 for a typical production home, with two-story homes requiring more ladder work at the higher end.
How we do it
We pull back existing insulation, foam-seal all top plate joints and interior wall intersections, caulk wire and plumbing penetrations, and replace insulation only after verifying seal completeness with a smoke pencil test.
Can Light & Duct Boot Sealing
Signs you need it
You see attic insulation dusting your furniture below can lights, your HVAC ducts show temperature loss at ceiling connections, or your home was built with non-IC-rated recessed lights.
What it costs in Cibolo
Can light and duct boot sealing in Cibolo runs $400-$1,200 depending on fixture count and whether we need to install fire-rated covers or replace with airtight IC-rated housings.
How we do it
We install pre-formed fire-rated covers over each can light, seal with high-temperature caulk, then mastic-seal duct boots to drywall and flex connections to eliminate conditioned air leakage to the attic.
What Attic Air Sealing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Top plate and penetration sealing | $800 - $2,200 |
| Can light and duct boot sealing | $400 - $1,200 |
| Full attic air sealing package | $1,500 - $3,500 |
Will air sealing alone lower my bills?
Yes, 10-20% savings are typical in Cibolo’s production homes with severe bypass leakage, though we recommend pairing with insulation replacement for the full performance change documented in your blower-door report. Call (830) 402-5240 for a written price on the combined scope.
How do you prove the sealing worked?
We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - before and after sealing, with both figures published in your documented record.
Wall Insulation in Cibolo
Wall insulation in Cibolo faces the hard limit of 2×4 exterior framing that volume builders used exclusively, restricting cavity insulation to R-13 or R-15 fiberglass batts that compress and settle over time. With no attic access to compensate for wall deficiencies in many two-story plans, and with summer heat radiating through unshaded east and west walls, Cibolo homeowners often find their walls are the weakest point in the envelope. Wall Insulation retrofits require specialized equipment but deliver measurable comfort changes.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in afternoon sun, rooms on the east and west sides have 5°F+ temperature swings, or your home was built with empty or poorly fitted batts visible at outlet removals.
What it costs in Cibolo
Injection foam wall insulation in Cibolo runs $3.00-$6.00 per square foot of wall area, or $4,500-$9,000 for a typical 2,000-square-foot home with 1,500 square feet of exterior wall.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam that fills around existing wiring and plumbing without pressure damage, then patch with matching texture and paint.
Drill & Fill Wall Insulation
Signs you need it
Your walls are currently uninsulated, you can hear outdoor conversations through exterior walls, or you’re remodeling and have drywall removed for access.
What it costs in Cibolo
Drill and fill with dense-pack cellulose in Cibolo runs $2.50-$4.50 per square foot, with open walls during renovation dropping to $1.50-$2.50 per square foot for new construction-grade access.
How we do it
We drill at the top of each stud bay, blow GreenFiber cellulose to 3.5 pounds per cubic foot density for minimal settling, verify fill completeness with thermal imaging, then patch and texture match.
What Wall Insulation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Injection foam (retrofit, per sq ft) | $3.00 - $6.00 |
| Drill & fill cellulose (retrofit, per sq ft) | $2.50 - $4.50 |
| Open-wall cellulose (during renovation) | $1.50 - $2.50 |
Will injection foam damage my walls?
No, slow-rise formulations expand at controlled pressure and our technicians verify bay capacity before injection; we’ve completed hundreds of retrofits without drywall blowout. Call (830) 402-5240 for a written price and access plan.
Can you insulate walls without removing drywall?
Yes, drill-and-fill methods access stud bays through exterior siding or interior drywall with minimal 2-inch holes that we patch and texture-match, typically completing a room in one day.
Attic Cleaning & Rodent Proofing in Cibolo
Attic cleaning and rodent proofing in Cibolo addresses the consequence of unsealed production homes: rodents exploit the same bypasses that leak conditioned air, nesting in settled fiberglass and compressing it further while contaminating the space. Cibolo’s rapid development displaced wildlife into remaining greenbelts and creek corridors, and pier-and-beam homes with unsealed crawl spaces provide entry points that lead upward into attics. Attic Cleaning & Rodent Proofing restores the space and closes the access paths.
Attic Sanitizing & Decontamination
Signs you need it
You find droppings in the attic or insulation, smell urine or musk through vents, or have had visible rodent activity in the past 12 months.
What it costs in Cibolo
Attic sanitizing and decontamination in Cibolo runs $1,500-$3,500 for a typical 1,500-square-foot attic, with heavy contamination requiring full insulation removal quoted separately.
How we do it
We remove contaminated material under HEPA containment, apply enzymatic cleaner to affected decking and framing, and run an ozone or hydroxyl treatment before any new insulation enters the space.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find entry holes around soffits or roof junctions, or have recurring rodent issues despite trapping or baiting programs.
What it costs in Cibolo
Rodent proofing and exclusion in Cibolo runs $800-$2,500 depending on entry point count, roof complexity, and whether we need to install metal flashing or hardware cloth at foundation gaps.
How we do it
We inspect every potential entry from foundation to ridge, seal with rodent-proof materials - steel mesh, concrete, metal flashing - and provide a written warranty on exclusion work for one year.
What Attic Cleaning & Rodent Proofing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic sanitizing and decontamination | $1,500 - $3,500 |
| Rodent proofing and exclusion | $800 - $2,500 |
| Full attic restoration (cleaning + insulation) | $3,500 - $7,500 |
How do I know rodents are gone before you reinsulate?
We set monitoring devices, seal all entry points, and wait 7-14 days with no activity before installing new insulation; we document the clear period in your photo record. Call (830) 402-5240 to schedule inspection.
Will rodents come back after exclusion?
Our one-year exclusion warranty covers re-entry through sealed points; if new entry develops, we return and address it under the same written scope at no additional cost.
Home Energy Audit in Cibolo
Home energy audit in Cibolo gives homeowners a documented baseline before spending on upgrades, which matters enormously in a market where every home shares the same construction era and the same likely deficiencies. The audit identifies whether your money is better spent on air sealing, insulation replacement, radiant barrier, or HVAC right-sizing - and in what order - rather than guessing based on neighbor recommendations or contractor preference. Home Energy Audit is the starting point for every major envelope job we quote.
Blower Door Test
Signs you need it
Your energy bills are 30% above similar homes, you feel persistent drafts, or you’re planning insulation work and want to measure the actual improvement rather than estimate it.
What it costs in Cibolo
A standalone blower-door test in Cibolo runs $300-$600, or it’s included at no charge when bundled with a full home energy audit or quoted insulation scope.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure - to quantify envelope tightness.
Thermal Imaging Inspection
Signs you need it
You have uneven temperatures room-to-room, suspect missing insulation in walls or vaulted ceilings, or want to verify contractor work from a previous job.
What it costs in Cibolo
Thermal imaging inspection in Cibolo runs $250-$500 as a standalone service, or combined with blower-door testing for $450-$900 depending on home size and scan complexity.
How we do it
We run the camera during blower-door depressurization to exaggerate thermal bypasses, documenting insulation gaps, air leaks, and moisture patterns with timestamped images in your report.
What Home Energy Audit Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Blower-door test (standalone) | $300 - $600 |
| Thermal imaging inspection (standalone) | $250 - $500 |
| Full home energy audit (combined) | $450 - $900 |
Will the audit tell me what to fix first?
Yes, your written report ranks recommendations by cost-effectiveness with estimated savings, so you can phase work by budget or tackle the highest-impact items first. Call (830) 402-5240 to schedule; the audit fee applies to any work we quote.
How long does a home energy audit take?
Most Cibolo audits take 2-4 hours depending on home size, with the blower-door test running 30 minutes and thermal imaging adding another 45 minutes to a full walkthrough.

What Cibolo Customers Say
"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E."Fixed price, clean work, and they hauled the old material away as agreed."
- Todd M."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.
