Insulation in Cibolo, TX
Crawl space encapsulation and vapor barrier installation in Cibolo typically runs $3,500-$7,500 for most homes, with radiant barrier and attic air sealing jobs adding another $1,200-$3,800 depending on roof complexity. Nearly every home we work on in Cibolo was built between 2000 and 2015 by a production builder rushing to meet demand, which means the original insulation was installed to pass inspection, not to perform. If your floors feel damp in spring or your HVAC runs nonstop through August, the building envelope is the problem, not the unit. Call (830) 420-0953 and we’ll start with a written price before any work starts.
Why Cibolo Homes Are Different
Cibolo’s housing stock is almost entirely post-2000 production-built tract homes, the majority constructed by D.R. Horton, Lennar, and KB Home along FM 78 and IH-35 corridors into Guadalupe County. These homes were framed with 2×4 walls, stuffed with fiberglass batts, and topped with blown-in fiberglass attics installed to minimum IRC code depths that met the letter of the law and little else. In IECC Climate Zone 2A, where attic temperatures crack 140°F and Gulf humidity pushes vapor inward through every gap, that minimum-grade work deteriorates fast. We’ve found compressed wall batts, thin eave edges with near-zero depth, and attic floors that were never sealed before insulation went in. After Winter Storm Uri in 2021, Cibolo homeowners learned the hard way that “new construction” and “well-insulated” are not the same thing. The February freeze triggered a sustained wave of upgrade calls from subdivisions near JBSA-Randolph where mid-2010s vintage homes were running oversized HVAC systems constantly without anyone realizing the attic insulation had settled below effective R-30.
Our Main Cibolo Services
Most Cibolo homeowners who call us start with attic work or spray foam. Here’s what those jobs look like here.
Attic Insulation in Cibolo
Attic insulation in Cibolo is almost always an upgrade or correction on a 10-to-20-year-old home, not a retrofit on vintage construction. We remove settled blown-in fiberglass, seal the attic floor properly, and reinstall to depth with Owens Corning or Johns Manville materials. Every job gets a written price before we start and a documented photo record when we leave. Attic Insulation in Cibolo
Spray Foam Insulation in Cibolo
Spray foam makes sense in Cibolo for bonus rooms over garages, sealed attics, and exterior walls where batts were compressed during original construction. We use open-cell and closed-cell products from Icynene and Demilec, selected for the application, not pushed as a default. The Haven Standard applies: written scope, written price, written warranty before anyone lifts a tool. Spray Foam Insulation in Cibolo
Blown-In Insulation in Cibolo
Blown-in fiberglass or cellulose is the most common attic upgrade in Cibolo because it corrects the original builder’s under-filled deck and thin eave edges. We blow GreenFiber cellulose or Knauf fiberglass after air sealing is complete, never before. The result is measured: before-and-after blower-door numbers on every applicable job.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Cibolo
Cibolo’s rapid growth means many homes sit on crawl spaces that were built quickly during the 2000s boom with minimal moisture protection and no sealed vapor barrier. Gulf Coast humidity pushes inward year-round, and the clay soils common to Guadalupe County wick moisture up through foundation walls. We’ve encapsulated crawl spaces in subdivisions from Turnberry to Deer Meadow where fiberglass batts hung below the floor joists had turned black with mold and dropped to the dirt. Crawl Space Encapsulation & Vapor Barrier is not an upsell here; it’s a correction of a fundamental building defect that the original construction process ignored.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare dirt or thin plastic sheeting, and the first floor feels humid even when the AC is running.
What it costs in Cibolo
Most Cibolo crawl space vapor barrier installations run $1,800-$3,500 for standard footprints under 2,000 square feet.
How we do it
We remove debris, grade the soil, lay 12-mil reinforced polyethylene with sealed seams and mechanical fastening to walls, then tape all penetrations.
Crawl Space Encapsulation
Signs you need it
You smell mustiness inside the home, see condensation on ductwork, or find mold on floor joists during a routine HVAC check.
What it costs in Cibolo
Full crawl space encapsulation in Cibolo typically ranges from $4,500-$8,500 depending on square footage, wall height, and whether a dehumidifier is required.
How we do it
We install rigid foam board on walls, seal all vents, apply vapor barrier to floors and walls, add a conditioned access door, and size a dedicated dehumidifier to the space.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Crawl space vapor barrier (standard footprint) | $1,800 - $3,500 |
| Partial encapsulation with wall sealing | $3,500 - $5,500 |
| Full encapsulation with dehumidifier | $4,500 - $8,500 |
How long does crawl space encapsulation take in Cibolo?
Most Cibolo crawl space encapsulations take 2-4 days depending on access, square footage, and whether mold remediation is needed first. We deliver a written schedule with the written price before work begins.
Will encapsulation stop my floors from feeling cold?
Yes, sealing the crawl space and adding wall insulation stops the stack effect that pulls cold, damp air up through the floor assembly. Call (830) 420-0953 for a free assessment and written price.
Radiant Barrier Installation in Cibolo
Cibolo attics hit 140-150°F in July and August, and the radiant heat gain through the roof deck is the primary load most HVAC systems fight. Production builders in the 2000s and 2010s rarely installed radiant barriers unless the buyer paid extra, which means most Cibolo homes rely on R-38 fiberglass alone to stop heat that radiates straight through the decking. A radiant barrier reflects that infrared energy back toward the roof deck, dropping attic surface temperatures by 20-30°F and reducing the delta-T across your insulation layer. Radiant Barrier Installation is one of the fastest-payback upgrades in Climate Zone 2A.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms run 8-12°F hotter than downstairs, and your AC cycles constantly after 2 p.m. even when the thermostat is satisfied.
What it costs in Cibolo
Attic radiant barrier installation in Cibolo typically costs $1,200-$2,800 for most single-story homes and $1,800-$3,500 for two-story or complex rooflines.
How we do it
We staple perforated foil-faced radiant barrier to the underside of roof rafters, maintaining ventilation channels and avoiding compression against the deck.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the radiant barrier integrated at the deck level rather than retrofitting foil to rafters later.
What it costs in Cibolo
Radiant barrier roof deck installation during re-roofing in Cibolo adds $0.75-$1.50 per square foot to the roofing scope, or $1,500-$3,200 as a standalone deck retrofit.
How we do it
We apply radiant barrier sheathing or foil directly to the deck, seal all seams with aluminum tape, and verify no gaps at valleys or ridges.
What Radiant Barrier Installation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Attic radiant barrier (rafter-stapled foil) | $1,200 - $3,500 |
| Radiant barrier roof deck (standalone) | $1,500 - $3,200 |
| Radiant barrier with attic air sealing package | $2,200 - $4,500 |
Does radiant barrier work with spray foam attics?
No, radiant barrier requires an air gap to function; spray foam applied directly to the roof deck eliminates that gap and makes radiant barrier redundant. We assess your attic configuration before recommending either approach.
How much will my electric bill drop?
Most Cibolo homeowners see 10-20% summer cooling reduction after radiant barrier plus air sealing, though exact savings depend on duct location and HVAC efficiency. Call (830) 420-0953 for a written estimate with projected payback.
Insulation Removal & Replacement in Cibolo
Cibolo’s post-2000 homes are reaching the age where original insulation has settled, been compromised by roof leaks, or contaminated by rodent activity in the attic. The February 2021 freeze accelerated damage in homes where ice dams backed water under shingles and into fiberglass batts. We remove insulation in subdivisions from Cibolo Crossing to The Meadows where homeowners discovered that what looked like “new” construction hid deteriorated material that no longer performed to labeled R-value. Insulation Removal & Replacement starts with a hazard assessment and ends with fresh material installed to depth.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed below the joist tops, shows water staining, or has been disturbed by prior contractor work without being restored.
What it costs in Cibolo
Attic insulation removal in Cibolo runs $1.00-$2.00 per square foot, or $1,200-$2,800 for a typical 2,000-square-foot footprint with standard access.
How we do it
We contain the attic space, use commercial vacuums with HEPA filtration to remove all loose material, bag it on-site, and dispose per local requirements.
Contaminated Insulation Removal
Signs you need it
You’ve found rodent droppings, smelled urine in the HVAC return, or seen insulation stained with biological contamination that standard removal won’t address.
What it costs in Cibolo
Contaminated insulation removal with sanitizing in Cibolo typically ranges from $2,500-$5,500 depending on contamination extent and whether deck replacement is needed.
How we do it
We remove all compromised material, apply enzymatic sanitizer to exposed surfaces, allow full dry time, and install new insulation only after clearance.
What Insulation Removal & Replacement Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Standard attic insulation removal | $1,200 - $2,800 |
| Contaminated insulation removal with sanitizing | $2,500 - $5,500 |
| Removal + replacement with air sealing | $3,500 - $7,500 |
Do I have to leave during insulation removal?
No, our containment and negative-air setup keeps living spaces isolated, though we recommend minimizing attic HVAC use during the removal phase. We notify you before starting each stage.
Can you remove insulation with asbestos?
We do not handle asbestos-containing material; if your Cibolo home was built before 1990 and you suspect vermiculite or asbestos batts, we arrange certified abatement before our scope begins. Call (830) 420-0953 for a free assessment.
Attic Air Sealing in Cibolo
Every insulation job we perform in Cibolo begins with air sealing, because blowing new material over an unsealed attic floor is building a blanket over a sieve. The production builders who framed Cibolo’s neighborhoods left top plates unsealed, can lights unboxed, and duct boots pulling conditioned air straight into the vented attic. Our blower-door tests in Cibolo homes regularly show 3,500-5,000 CFM50 before sealing and 1,800-2,800 after, which is the performance change homeowners actually paid for. Attic Air Sealing is not optional under The Haven Standard; it’s Clause 1 of a job done right.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at outlets on exterior walls, or your blower-door test shows excessive leakage at the attic floor plane despite adequate insulation depth.
What it costs in Cibolo
Top plate and penetration sealing in Cibolo typically runs $800-$1,800 for a standard attic with accessible framing and 15-25 penetrations.
How we do it
We access top plates at eaves and interior walls, seal with fire-rated caulk and foam, box all electrical and plumbing penetrations, and verify with blower-door retest.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed can lights are original non-IC fixtures, or your HVAC ducts show dust accumulation at attic connections indicating conditioned air leakage.
What it costs in Cibolo
Can light sealing with proper covers and duct boot sealing in Cibolo costs $600-$1,500 depending on fixture count and duct configuration.
How we do it
We install fire-rated airtight covers over non-IC cans, seal with mastic at duct boots, and pressure-test the duct system where accessible.
What Attic Air Sealing Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Top plate and penetration sealing | $800 - $1,800 |
| Can light and duct boot sealing | $600 - $1,500 |
| Full attic air sealing with blower-door verification | $1,500 - $3,200 |
Will air sealing make my attic too tight?
No, we maintain required ventilation through soffit, ridge, and gable vents; sealing the floor plane stops conditioned air escape without trapping moisture. Every job gets before-and-after blower-door numbers to confirm.
Can air sealing alone lower my bill?
Yes, many Cibolo homeowners see 15-25% HVAC savings from air sealing alone before insulation is upgraded, because the conditioned air they’re paying to create stops escaping. Call (830) 420-0953 for a written scope and price.
Wall Insulation in Cibolo
Cibolo’s 2×4 framed walls were originally filled with fiberglass batts installed quickly by crews paid by the house, not by the quality of the fill. We’ve opened walls in homes near Green Valley Road and found batts compressed behind electrical boxes, gaps at stud bays, and exterior sheathing with no continuous insulation layer. In Climate Zone 2A, that means heat conducts straight through the framing fraction and inward vapor drive finds pathways around the insulation. Wall Insulation in Cibolo is typically a retrofit for comfort complaints or part of a remodel, not a new-construction decision.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, rooms have uneven temperatures, or you’re remodeling and can see the original batt compression when drywall is removed.
What it costs in Cibolo
Injection foam wall insulation in Cibolo runs $3.00-$5.50 per square foot of wall area, or $2,800-$5,500 for a typical 1,500-square-foot wall system.
How we do it
We drill 5/8-inch holes at stud-bay intervals, inject slow-rise foam to fill completely without bowing drywall, then plug and texture-match.
Drill & Fill Wall Insulation
Signs you need it
You need wall insulation without full interior demolition, and your walls are balloon-framed or have minimal obstructions in the stud bay.
What it costs in Cibolo
Drill and fill with dense-pack cellulose in Cibolo costs $2.00-$4.00 per square foot, or $2,200-$4,500 for standard residential wall footage.
How we do it
We drill exterior or interior access holes, dense-pack cellulose to 3.5 pounds per cubic foot for no-settle performance, seal penetrations, and verify fill with thermal imaging.
What Wall Insulation Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Injection foam wall insulation | $2,800 - $5,500 |
| Drill and fill dense-pack cellulose | $2,200 - $4,500 |
| Exterior wall insulation with remediation | $4,500 - $8,500 |
Will injection foam damage my walls?
No, slow-rise formulations are spec’d precisely for retrofit applications and won’t bow studs or crack drywall when installed by trained technicians. We document the wall condition before and after with photos.
Can you insulate walls without removing drywall?
Yes, drill-and-fill methods access stud bays through small holes that are plugged and finished afterward, making this ideal for Cibolo homes where you’re not planning a full remodel. Call (830) 420-0953 for a written assessment.
Attic Cleaning & Rodent Proofing in Cibolo
Cibolo’s growth into former ranchland means attics here interface with active wildlife corridors, and the mature oaks in established neighborhoods provide highway access for squirrels and roof rats. We clean attics in subdivisions from Alamo Ranch to Wolf Crossing where homeowners discovered rodent damage years after the initial intrusion, with compressed trails through fiberglass and biological contamination that standard pest control doesn’t address. The original builder-minimum insulation in these homes provides nesting material, not a barrier. Attic Cleaning & Rodent Proofing removes the contamination and closes the entry paths so it doesn’t recur.
Attic Sanitizing & Decontamination
Signs you need it
You’ve found rodent droppings in the attic, smell urine through the HVAC system, or see staining on insulation that indicates biological contamination.
What it costs in Cibolo
Attic sanitizing and decontamination in Cibolo typically runs $1,500-$3,500 for standard footprints with moderate contamination and accessible joist bays.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzymatic sanitizer, allow full dwell and dry time, and provide photo documentation of the cleared space.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in the ceiling, find gnaw marks at roofline vents, or have had repeated pest control visits without resolving the attic access.
What it costs in Cibolo
Rodent proofing and exclusion in Cibolo costs $800-$2,200 depending on roof complexity, entry point count, and whether soffit or ridge vent replacement is needed.
How we do it
We inspect the roofline, seal all penetrations larger than 1/4 inch with rodent-proof materials, install hardware cloth over vents, and guarantee the exclusion 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 - $2,200 |
| Full attic restoration with insulation replacement | $4,500 - $9,500 |
How do I know if rodents are in my attic?
Listen for scratching at dawn and dusk, check for droppings near attic hatches, and look for gnaw marks on PVC vent pipes or soffit screens. We include a full inspection with every written estimate.
Will proofing keep all wildlife out?
Our exclusion targets rodents specifically; larger wildlife like raccoons require different hardware. We assess the species from evidence and spec the right barrier. Call (830) 420-0953 for a written scope.
Home Energy Audit in Cibolo
A home energy audit in Cibolo reveals the performance gap between what your home was supposed to do and what it actually does, which is substantial in production-built housing from the 2000s and 2010s. We audit homes near Cibolo Valley Ranch and along FM 78 where homeowners assumed high electric bills were normal for Texas summers until a blower-door test showed them exactly where conditioned air was escaping. The audit produces a prioritized scope with written prices for each measure, so you decide what to tackle and when. Home Energy Audit is the starting point for every envelope improvement we recommend.
Blower Door Test
Signs you need it
Your HVAC runs excessively, rooms have uneven temperatures, or you’re considering insulation upgrades and want to know air leakage before spending on material.
What it costs in Cibolo
A standalone blower-door test in Cibolo costs $300-$500, or it’s included at no charge when bundled with a full home energy audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage and identify dominant leak paths.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls or ceilings, have had ice dam or moisture issues, or want visual documentation of thermal bypasses before committing to work.
What it costs in Cibolo
Thermal imaging inspection in Cibolo runs $250-$450 as a standalone service, or it’s included in the comprehensive audit package.
How we do it
We scan the building envelope with a FLIR camera during blower-door depressurization to make air leakage visible, then produce annotated images showing temperature differentials and problem locations.
What Home Energy Audit Costs in Cibolo
| Item | Typical range in Cibolo |
|---|---|
| Standalone blower-door test | $300 - $500 |
| Thermal imaging inspection | $250 - $450 |
| Comprehensive home energy audit | $400 - $800 |
What does the audit report include?
You receive blower-door numbers, thermal images with annotations, a prioritized scope of recommended work, and written prices for each measure. No work starts without your written approval.
Is the audit fee credited toward work?
Yes, the comprehensive audit fee is applied to any envelope work you schedule within 90 days. Call (830) 420-0953 to book; we dispatch from our San Antonio office and serve Cibolo locally.

What Cibolo 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."Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
- Ainsley P."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."
