Insulation in Cibolo, TX
Crawl space encapsulation and vapor barrier work in Cibolo starts with a reality check: this city built out so fast that most homes sit on slab foundations, not crawl spaces. When we do encounter a crawl space in Cibolo, it’s usually in a custom build or an outlier property near the older fringe, and it’s almost never been properly sealed against the humid Gulf air that pushes up from the southeast. Call (737) 227-6219 and we’ll tell you straight whether your home even has a crawl space worth encapsulating, or if your money is better spent on attic air sealing and insulation.
Why Cibolo Homes Are Different
Cibolo’s entire housing stock is young by Texas standards, built between roughly 2000 and 2024 in master-planned subdivisions like Steele Creek and Cibolo Valley. Production builders installed blown fiberglass to the minimum IRC or IECC code of the construction year, not today’s standards. Summer attic temperatures here routinely top 150°F, and CPS Energy cooling bills dominate household budgets. The February 2021 Winter Storm Uri exposed how thin insulation left pipes vulnerable in these tract homes. In two-story subdivisions, the upper floor runs 8-12°F hotter than the lower floor, a direct result of builder-minimum attic insulation combined with West and South roof exposures. This is the complaint we hear most often in newer Cibolo neighborhoods.
Our Main Cibolo Services
Most Cibolo homeowners start with attic work or spray foam, but we also handle blown-in upgrades for settled insulation.
Attic Insulation in Cibolo
Attic insulation in Cibolo means adding depth to builder-grade blown fiberglass that has settled below R-30 in attics that hit 150°F. We air seal first, then insulate, and publish before-and-after blower-door numbers so you can verify the performance change. Attic Insulation in Cibolo covers the full scope for homes in Steele Creek, Cibolo Valley, and throughout the city.
Spray Foam Insulation in Cibolo
Spray foam insulation in Cibolo works best for open attics, rim joists, and bonus rooms where fiberglass can’t form a continuous thermal boundary. We use open-cell and closed-cell products from Owens Corning and Demilec, applied after air sealing is complete. Spray Foam Insulation in Cibolo details our application standards and pricing.
Blown-In Insulation in Cibolo
Blown-in insulation in Cibolo is the most common upgrade for tract homes with settled fiberglass. We remove the compressed layer or add new blown fiberglass or cellulose on top, depending on condition and your budget. Blown-In Insulation in Cibolo explains our density and coverage standards.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Cibolo
Crawl space encapsulation and vapor barrier work in Cibolo is uncommon because the city’s rapid growth produced almost exclusively slab-on-grade construction in subdivisions like Steele Creek and Cibolo Valley. When we do find a crawl space, it’s typically a custom home or an older property on the fringe, and it’s almost never been sealed against the humid air that rolls up from the Gulf. Crawl Space Encapsulation & Vapor Barrier covers our full protocol, but we’ll be direct: most Cibolo homes don’t have crawl spaces, and we’d rather redirect you to attic air sealing than sell you work you don’t need.
Crawl Space Vapor Barrier
Signs you need it
Standing water, mold on floor joists, or a dirt floor that smells musty even in dry weather means the vapor barrier has failed or was never installed.
What it costs in Cibolo
Most crawl space vapor barrier jobs in Cibolo run $1,200 to $2,800 for a standard 1,000-square-foot footprint, with thicker reinforced poly and full seam taping at the higher end.
How we do it
We remove debris, grade the soil, lay 10-mil or thicker reinforced polyethylene with sealed seams, and extend it 6 inches up foundation walls before sealing to the wall.
Crawl Space Encapsulation
Signs you need it
Chronic humidity above 70 percent, buckling hardwood floors above, or HVAC ducts sweating in the crawl space indicate the space is exchanging air with the outside.
What it costs in Cibolo
Full crawl space encapsulation in Cibolo typically ranges from $3,500 to $7,500 depending on square footage, wall height, and whether a dehumidifier is required.
How we do it
We install vapor barrier across floors and walls, seal all vents and penetrations, add mechanical dehumidification if needed, and verify with humidity monitoring.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Crawl space vapor barrier (1,000 sq ft) | $1,200 - $2,800 |
| Partial encapsulation (walls only) | $2,000 - $4,500 |
| Full encapsulation with dehumidifier | $3,500 - $7,500 |
Do most Cibolo homes even have crawl spaces?
No. Call (737) 227-6219 and we’ll confirm your foundation type before scheduling.
What does the 365-Day Done Right Promise cover for encapsulation?
If humidity rises above the agreed target or seams fail within one year, we return and fix it at no charge. The written scope and warranty are delivered before work starts.
Radiant Barrier Installation in Cibolo
Radiant barrier installation in Cibolo addresses the specific problem of West and South roof exposures that turn attics into 150°F ovens for six months of the year. Production builders in subdivisions like Steele Creek and Cibolo Valley rarely installed radiant barriers even during the 2010s boom, leaving homeowners to absorb that radiant heat through thin ceiling drywall. Radiant Barrier Installation is one of our most requested upgrades in Cibolo because it directly attacks the upper-floor temperature imbalance that builder-minimum insulation created.
Attic Radiant Barrier
Signs you need it
Your upper floor stays 8-12°F hotter than the lower floor even when the AC runs continuously, and ceiling surfaces feel warm to the touch in summer afternoons.
What it costs in Cibolo
Attic radiant barrier installation in Cibolo typically runs $1,500 to $3,200 for a standard two-story tract home, depending on attic square footage and accessibility.
How we do it
We staple perforated aluminum foil across rafter bottoms or drape it over existing insulation, maintaining ventilation channels so moisture doesn’t trap.
Radiant Barrier Roof Deck
Signs you need it
New roof installation is planned, or your existing shingles are failing prematurely from extreme attic heat cycling.
What it costs in Cibolo
Radiant barrier roof deck application in Cibolo ranges from $2,000 to $4,500 when done during reroofing, or $3,500 to $6,500 as a standalone retrofit.
How we do it
We apply reflective sheathing or spray-applied radiant coating directly to the roof deck underside, sealing the thermal bridge at the highest heat-gain point.
What Radiant Barrier Installation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic radiant barrier (foil over insulation) | $1,500 - $3,200 |
| Radiant barrier roof deck (with reroof) | $2,000 - $4,500 |
| Radiant barrier roof deck (retrofit) | $3,500 - $6,500 |
Will a radiant barrier fix my hot upstairs?
It will reduce radiant heat gain significantly, but we always pair it with attic air sealing and added insulation depth for the full fix. Call (737) 227-6219 for a blower-door test and written scope.
How long does radiant barrier installation take?
Most Cibolo attic radiant barrier jobs finish in one day; roof deck application during reroofing adds no time to the roofing schedule.
Insulation Removal & Replacement in Cibolo
Insulation removal and replacement in Cibolo is increasingly common as the first wave of 2000-2010 tract homes hits 15-20 years of age. Builder-grade blown fiberglass settles, compresses, and in some cases harbors moisture or rodent activity from roof leaks that went undetected in attic spaces. Insulation Removal & Replacement lets us start fresh with a clean deck, proper air sealing, and new material installed to current depth standards rather than the minimum code of the build year.
Attic Insulation Removal
Signs you need it
Insulation is compressed below the joist tops, has dark staining from past leaks, or emits a musty odor when the attic hatch is opened.
What it costs in Cibolo
Attic insulation removal in Cibolo typically runs $1.00 to $2.50 per square foot, so a standard 2,000-square-foot attic costs $2,000 to $5,000 to clear and dispose.
How we do it
We use commercial vacuums with HEPA filtration to remove old material without contaminating living spaces, then inspect decking for damage before proceeding.
Contaminated Insulation Removal
Signs you need it
Rodent droppings, urine staining, or mold growth are visible in the insulation, or an HVAC duct leak has saturated fiberglass with condensate.
What it costs in Cibolo
Contaminated insulation removal in Cibolo ranges from $3,000 to $7,500 depending on contamination extent, required PPE, and whether sanitizing or mold remediation precedes new installation.
How we do it
We bag contaminated material under negative air pressure, apply EPA-registered sanitizers to affected surfaces, and document with photos before installing new insulation.
What Insulation Removal & Replacement Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Standard attic insulation removal | $2,000 - $5,000 |
| Contaminated insulation removal | $3,000 - $7,500 |
| Removal + replacement with new R-38 to R-49 | $5,500 - $12,000 |
Can you remove insulation without tearing out my ceiling?
Yes. We access through the attic hatch and use vacuum extraction; ceiling drywall stays intact. Call (737) 227-6219 for a free inspection and written price.
Do I need to leave during removal?
Not for standard removal, though we recommend it during contaminated material extraction. We seal the attic access and run negative air machines to protect living spaces.
Attic Air Sealing in Cibolo
Attic air sealing in Cibolo is the single most impactful upgrade for homes built during the 2000-2020 boom, because production builders prioritized speed over envelope tightness. Top plates, can lights, duct boots, and plumbing penetrations leak conditioned air directly into vented attics that hit 150°F, forcing your AC to replace that lost cooling continuously. Attic Air Sealing is always our first step before adding insulation; we will never blow new material over an unsealed attic floor, and we publish before-and-after blower-door numbers to prove the reduction in air leakage.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks on ceiling drywall near wall tops, or rooms that stay uncomfortable despite adequate insulation depth, indicate top plate leakage.
What it costs in Cibolo
Top plate and penetration sealing in Cibolo typically runs $800 to $2,000 for a standard two-story tract home, depending on linear footage and access difficulty.
How we do it
We seal all top plate gaps with fire-rated caulk or foam, wrap penetrations with gasket material, and verify with blower-door directed air flow measurement.
Can Light & Duct Boot Sealing
Signs you need it
Recessed can lights feel drafty in winter, or supply ducts blow weakly at far registers while the attic near the air handler is ice-cold in summer.
What it costs in Cibolo
Can light and duct boot sealing in Cibolo ranges from $500 to $1,500 depending on fixture count and whether boots require mastic replacement or full rebuild.
How we do it
We install fire-rated covers over non-IC cans, seal with high-temperature caulk, and apply mastic to all duct collar connections before testing with pressure pan readings.
What Attic Air Sealing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Top plate & penetration sealing | $800 - $2,000 |
| Can light & duct boot sealing | $500 - $1,500 |
| Full attic air sealing (comprehensive) | $1,500 - $3,500 |
Will air sealing alone fix my hot upstairs?
It will reduce the temperature gap significantly by stopping conditioned air loss, but we typically pair it with added insulation depth for full comfort. Call (737) 227-6219 for a blower-door test.
What blower-door improvement should I expect?
Most Cibolo tract homes start at 3,500-5,000 CFM50 and finish at 2,000-3,000 CFM50 after comprehensive attic air sealing, a 30-40 percent reduction in envelope leakage.
Wall Insulation in Cibolo
Wall insulation in Cibolo is challenging because production builders in Steele Creek, Cibolo Valley, and similar subdivisions filled stud cavities with minimal fiberglass batts and called it code-compliant. Those batts sag, compress, and leave gaps behind electrical boxes and plumbing stacks. Wall Insulation for Cibolo homes usually means dense-pack injection or drill-and-fill retrofit, since gutting finished interiors is rarely practical in homes built 8-15 years ago.
Injection Foam Wall Insulation
Signs you need it
Exterior walls feel hot to the touch in summer, cold in winter, or you can feel air movement around outlets and switch plates on exterior walls.
What it costs in Cibolo
Injection foam wall insulation in Cibolo typically runs $3.00 to $6.00 per square foot of wall area, so a 2,000-square-foot home with 3,000 square feet of exterior wall runs $9,000 to $18,000.
How we do it
We drill 2-inch holes through siding or interior drywall at stud-bay intervals, inject slow-rise foam under pressure to fill gaps, then patch and match finish.
Drill & Fill Wall Insulation
Signs you need it
Rooms with two or more exterior walls are consistently 5°F different from interior rooms, or energy bills spike despite adequate attic insulation.
What it costs in Cibolo
Drill-and-fill with blown fiberglass or cellulose in Cibolo ranges from $2.00 to $4.50 per square foot, making it a lower-cost alternative to foam for budget-conscious homeowners.
How we do it
We drill access holes at top and bottom of each stud bay, blow material to verified density with hose-mounted counters, then seal and patch all penetrations.
What Wall Insulation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Drill & fill (blown fiberglass/cellulose) | $2.00 - $4.50/sq ft |
| Injection foam (open-cell) | $3.00 - $5.00/sq ft |
| Injection foam (closed-cell) | $4.50 - $6.00/sq ft |
Will wall insulation require tearing out my drywall?
No. We access through exterior siding or small interior patches; finished rooms stay intact. Call (737) 227-6219 for a free assessment and written price.
How much does wall insulation improve comfort?
Most Cibolo homeowners report 3-6°F more stable temperatures in previously problematic rooms, with reduced HVAC cycling and more even temperatures between floors.
Attic Cleaning & Rodent Proofing in Cibolo
Attic cleaning and rodent proofing in Cibolo has become more frequent as the city’s young housing stock ages just enough for roof penetrations, vent screens, and soffit gaps to deteriorate. Mice and roof rats exploit these entry points, contaminating insulation with droppings and compressing it with nesting activity. Attic Cleaning & Rodent Proofing restores the attic to a clean, sealed condition so new insulation performs as designed rather than sitting on top of biohazardous debris.
Attic Sanitizing & Decontamination
Signs you need it
Musty odors filter through ceiling penetrations, or visible droppings and urine staining appear on insulation surfaces and attic decking.
What it costs in Cibolo
Attic sanitizing and decontamination in Cibolo typically runs $1,500 to $4,000 depending on square footage, contamination density, and whether insulation removal precedes treatment.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzyme-based sanitizers to break down organic waste, and run air scrubbers until clearance testing passes.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in ceilings at night, gnaw marks on fascia boards, or daylight visible through gaps where roof lines meet soffits indicate active entry points.
What it costs in Cibolo
Rodent proofing and exclusion in Cibolo ranges from $800 to $2,500 for a standard two-story home, with extensive roofline work or multiple entry points at the higher end.
How we do it
We inspect every roof penetration, vent, and soffit joint with photo documentation, seal entry points with rodent-proof materials, and install mechanical barriers where gnawing is likely.
What Attic Cleaning & Rodent Proofing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic sanitizing & decontamination | $1,500 - $4,000 |
| Rodent proofing & exclusion | $800 - $2,500 |
| Full attic restoration (cleanout + proofing + new insulation) | $4,500 - $10,000 |
Do you handle the rodents or just seal after?
We partner with licensed pest control for active infestations, then perform exclusion and restoration. Call (737) 227-6219 and we’ll coordinate the sequence.
How do I know rodents won’t return?
Our exclusion work carries the 365-Day Done Right Promise: if rodents re-enter through any sealed point within one year, we return and reinforce at no charge.
Home Energy Audit in Cibolo
A home energy audit in Cibolo gives homeowners the documentation they need to prioritize envelope upgrades in a city where every house is young but built to outdated minimums. The audit identifies whether your 8-15 year-old home’s discomfort stems from attic insulation, duct leakage, wall gaps, or all three. Home Energy Audit delivers a written scope with prioritized recommendations and expected savings, so you can make decisions based on measured data rather than guesswork.
Blower Door Test
Signs you need it
Rooms that never reach set temperature, excessive dust, or energy bills that exceed comparable neighbors’ by 30 percent or more suggest major envelope leakage.
What it costs in Cibolo
A standalone blower-door test in Cibolo typically runs $300 to $600, or it’s included at no charge when bundled with a full home energy audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage in one number.
Thermal Imaging Inspection
Signs you need it
Visible temperature variations on ceilings or walls, or rooms that feel drafty despite closed windows and doors, indicate insulation gaps or air leakage paths.
What it costs in Cibolo
Thermal imaging inspection in Cibolo ranges from $250 to $500 as a standalone service, or it’s included in our comprehensive audit package.
How we do it
We use FLIR cameras during blower-door depressurization to visualize air infiltration paths and insulation voids, then mark findings on floor plans for your records.
What Home Energy Audit Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Standalone blower-door test | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Comprehensive home energy audit | $400 - $800 |
Will the audit tell me exactly what to fix first?
Yes. You receive a written priority list with estimated savings and costs for each measure, ranked by payback period. Call (737) 227-6219 to schedule.
How long does a home energy audit take?
Most Cibolo audits take 2-3 hours for a two-story tract home, with same-day preliminary findings and full documentation within 48 hours.

FAQs About Insulation in Cibolo
Most attic insulation and air-sealing upgrades don’t require permits in Cibolo, but spray foam and any structural modification do. We pull permits when required and handle HOA notification for subdivisions with architectural review boards.
Most Cibolo homeowners get an inspection within 48 hours and work scheduled within one week. Emergency situations, like post-storm water damage to insulation, get same-day response when crews are available.
Texas energy code allows minimum insulation levels that perform poorly in 150°F attics. Your 2020 home likely has R-30 settled fiberglass and minimal air sealing, not the R-49 and tight envelope that current best practice recommends. A home energy audit measures exactly where your specific home falls short.
