Attic Insulation in Cibolo - Same-Day Service, Done Right the First Time

Fast, Reliable Attic Insulation Across Cibolo

Most attic insulation upgrades in Cibolo run $2,200-$4,800 for a typical 2,000-square-foot production home, with same-week scheduling available and crews dispatched from our San Antonio office. If your home was built between 2005 and 2020 in The Crossvine or another Cibolo subdivision, you’re likely living with builder-minimum R-30 fiberglass that has settled below its original rating and unsealed top plates that let 150°F attic air bypass it entirely.

We know Cibolo’s housing stock because we’ve worked inside it. The same DR Horton, Lennar, and KB Home floor plans repeat across the city, and so do the same insulation shortcuts. Our crews don’t guess at what’s in your attic. We’ve pulled back enough settled fiberglass in Cibolo homes to know exactly where the gaps hide before we arrive.

Why Topside Attic Insulation Schertz Is Cibolo’s Preferred Attic Insulation Company

We’ve sealed and insulated homes in The Crossvine, Cibolo Valley Ranch, and the neighborhoods along FM 1103 since we started tracking every job with a written scope and photo record. Our Cibolo customers leave reviews that mention the same thing: the crew showed the blower-door numbers, explained what they meant, and left documentation behind. We don’t ask you to trust a feeling. We hand you a folder with before-and-after pressurization readings, photos of every sealed gap, and a written warranty.

Response time to Cibolo is typically same-day or next-day for estimates, with crews carrying Owens Corning, Johns Manville, and GreenFiber materials so we’re not waiting on a distributor run. Our scheduling runs from the San Antonio office, but the trucks that roll to Cibolo are stocked for Cibolo’s specific housing stock: the right baffles for shallow-pitch builder trusses, the right sealant for the unsealed top plates we know we’ll find, and enough blown fiberglass to take a settled R-30 back to a full R-38.

Under Haven Standard Clause 1, you get a written price before any work starts. No exceptions. That written scope includes exactly which top plates get sealed, how many baffles get installed at the soffits, and the final R-value you’ll have when we leave. Our 365-Day Done Right Promise covers every Cibolo job, and a live person answers (830) 402-5240 around the clock.

Our Attic Insulation Services in Cibolo

Blown-In Attic Insulation

Blown-in fiberglass is the right fix for most Cibolo homes because it fills irregular joist bays and covers the settled, uneven layers left by builder-original R-30 installs. We use a blowing machine to distribute Owens Corning or Johns Manville loose-fill fiberglass across the attic floor, achieving consistent depth and density that hand-placed batts can’t match in truss-framed attics with angled ceiling planes. Every blown-in job in Cibolo starts with air sealing, not after. We seal top plates, electrical penetrations, and interior partition walls before the blower truck starts. The result is a documented R-38 with verified air-leak reduction, not just more material on top of the same gaps.

Attic Batt Insulation

Batt insulation has a place in Cibolo homes, but it’s rarely the primary attic solution. We use Knauf or Owens Corning fiberglass batts for specific applications: knee walls in bonus rooms, vertical gable ends, and attic hatches where blown fill won’t stay put. In Cibolo’s production homes, batts are most often part of a hybrid system - blown fill across the main attic floor, batts in the vertical or confined spaces. We don’t sell batts as a standalone attic solution when your attic floor is uneven truss framing with dozens of penetrations. The written scope tells you exactly where batts go and why.

Attic Insulation Top-Up

This is the most common service we perform in Cibolo. Your builder installed R-30 blown fiberglass 12-18 years ago. It has settled to R-19 or R-22. Your HVAC runs longer each August. A top-up brings the attic back to R-38 by adding new blown fiberglass over the existing layer, but only after we air-seal the bypasses that developed or were missed originally. The typical Cibolo top-up runs $2,200-$3,600 and takes one day. We prep baffles at the soffits to maintain ventilation, seal every accessible top plate and penetration, then blow to a uniform depth. You get before-and-after blower-door numbers if the job qualifies, plus the photo record showing every sealed gap.

Attic Insulation Replacement

Replacement means removal of the existing insulation, remediation of any contamination or degradation, and installation of new material. In Cibolo, we see this need after rodent activity, water intrusion from roof leaks, or severe settling that has compressed fiberglass into an ineffective mat. Replacement runs $3,800-$6,200 for a typical Cibolo tract home and requires a full day, sometimes two. We remove the old material with commercial vacuums, inspect and seal the attic floor completely, then install new blown fiberglass to R-38 with proper baffles and ventilation prep. The written scope specifies exactly what gets removed, what gets sealed, and what goes back in.

Attic Baffles & Ventilation Prep

Cibolo’s hot-humid climate (IECC Zone 2) demands attic ventilation that works. Baffles - also called rafter vents or vent chutes - keep soffit intake air flowing up the underside of the roof deck instead of getting blocked by insulation at the eaves. In Cibolo’s production homes, builders often skipped baffles or used the cheapest cardboard versions that collapsed under blown fill. We install rigid plastic or foam baffles at every soffit bay, ensuring continuous airflow from eave to ridge vent. Without this step, your new insulation traps moisture against the roof deck and your attic becomes a convection oven. We include baffle installation in every full attic job, and we’ll specify the count and type in your written scope.

Trusted Brands We Service in Cibolo

We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber - no proprietary lock-in, no mystery products. Our Cibolo trucks carry Owens Corning blown fiberglass in R-38 equivalent bags, Johns Manville batts for hybrid applications, and Knauf loose-fill for jobs where density and coverage are the priority. Because we stock locally and coordinate from the San Antonio office, we don’t delay your job waiting on a special order. The brand on your attic floor is listed in your written scope, with product data sheets available if you want them.

Common Attic Insulation Problems We See in Cibolo Homes

• Settled R-30 fiberglass below original rating. Builder-minimum blown fiberglass installed 10-20 years ago has compacted to R-19-R-25, leaving your ceiling as a radiant heat receptor for 150°F attic air. We measure actual depth on every inspection and show you the number.
• Unsealed top plates and interior partition gaps. Volume builders across Cibolo’s boom years skipped sealing the framing gaps above interior walls. Hot attic air pours through these bypasses straight into your conditioned space, bypassing the insulation entirely. We find these in nearly every Cibolo attic we open.
• Missing or collapsed attic baffles. Soffit ventilation gets blocked by insulation that falls against the eave, killing airflow and trapping heat. In Cibolo’s climate, this accelerates shingle degradation and drives cooling costs up. We install rigid baffles that survive the next insulation cycle.
• 2×4 wall cavities that cap at R-13/R-15. Cibolo’s production homes have thin walls by design. The ceiling plane is your only real thermal defense. When the attic layer is compromised, there’s nowhere else for the heat to go except through your drywall and into your living room.
