We’re usually on-site in Cibolo within 24-48 hours of your call, and most jobs finish in a single day. Call (830) 243-6352 for a written price before any work starts - that’s Haven Standard Clause 1.
We know Cibolo’s housing stock because we work in it constantly: Bentwood Ranch, Cibolo Crossing, the whole corridor of post-2000 subdivisions built during one of Texas’s fastest growth spurts. These aren’t aging farmhouses with quirky construction. They’re slab-on-grade two-story tract homes built fast, built to minimum code, and now hitting the same insulation decay milestone all at once. Our crews are dispatched from our San Antonio office, but we serve Cibolo locally and understand the specific failure modes these homes develop.
Why Topside Attic Insulation New Braunfels Is Cibolo’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a significant cluster of those have been in Cibolo’s uniform subdivisions. The pattern is unmistakable: entire streets in Bentwood Ranch booking top-ups within months of each other as original R-30 fiberglass settles to R-19 or less. Our Cibolo customers leave reviews citing the blower-door numbers we publish, the photo records we deliver, and the fact that we don’t try to sell insulation before we seal the air leaks.
Response time to Cibolo is typically same-day or next-day for standard calls, with emergency scheduling available when attic temperatures are driving compressor failure or when freeze risk is imminent. Our technicians are background-checked, uniformed, and named - you’ll get a text when yours is en route, under Haven Standard: Arrive on schedule.
What builds trust in Cibolo specifically is our documentation. Every job gets a written scope, a written warranty, and a Documented Photo Record. On air-sealing jobs, you get before-and-after blower-door readings - a pressurization measurement that shows, in one number, how much conditioned air your home was losing before and after the work. No guesswork. No “trust us, it’s better.”
Our Attic Insulation Services in Cibolo
Attic Insulation Top-Up
This is our most common call in Cibolo. The mid-2000s blown fiberglass in your attic has compacted. It happens to everyone on your street at roughly the same time. A top-up adds new material over the settled layer, but only after we air-seal the top plates, can lights, and wiring penetrations - otherwise you’re just burying the leaks deeper. Most Cibolo top-ups run $1,200-$2,800 depending on attic square footage and current depth. We use Owens Corning or Johns Manville blown fiberglass, matched to what’s there.
Blown-In Attic Insulation
New installation or full replacement of failed material. In Cibolo’s 150°F-plus summer attics, proper depth and density matter more than the sticker R-value. We install to true depth, not settled depth, and we verify with photos you can see. Our Attic Insulation team uses Knauf or Owens Corning loose-fill, blown to spec with calibrated equipment. Full replacements in Cibolo’s typical 2,400-3,200 square foot two-story homes run $2,400-$4,200.
Attic Batt Insulation
Used in specific Cibolo applications: knee walls, attic storage platforms, or areas where blown-in won’t hold position. We cut batts to fit without compression gaps - a common shortcut in original construction that destroys R-value. Rockwool batts for fire-blocking near chimney chases or Owens Corning fiberglass for standard thermal applications. Batt work is typically priced as an add-on to blown-in service, $400-$900 depending on linear footage.
Attic Insulation Replacement
When the original material is contaminated, water-damaged, or so compacted that topping up won’t achieve target R-value. We remove, dispose, and start fresh. This is more common in Cibolo after roof leaks or rodent activity in the attic. Replacement jobs include full air sealing as a prerequisite - we will never blow new insulation over an unsealed attic floor. Typical range: $3,200-$5,800 for Cibolo’s standard two-story footprint.
Attic Baffles & Ventilation Prep
Cibolo’s tract homes were built with minimal soffit intake ventilation, and original baffles get buried or knocked out during construction. Without baffles, new blown-in insulation pushes into the eaves and blocks what little airflow existed. We install or re-set proper baffles before adding material, ensuring the intake path stays open. This is standard on every Cibolo blown-in job - not an upsell. Materials cost is minimal; labor is included in the scope.

Before
AfterTrusted Brands We Service in Cibolo
We source from Owens Corning, Johns Manville, Knauf, and Rockwool - no proprietary lock-in, no house brand with inflated margins. For Cibolo’s climate, we typically specify Owens Corning AttiCat blown fiberglass for top-ups and replacements: it maintains loft in high-heat attics better than lower-density alternatives. Rockwool comes into play for fire-blocking and sound attenuation in shared-wall or chimney-adjacent applications. We stock standard materials locally, so Cibolo jobs don’t wait on freight. If your home has existing Johns Manville or Knauf insulation, we match the new material for compatibility - mixing fiber types without understanding binder chemistry can cause settling issues down the line.
Common Attic Insulation Problems We See in Cibolo Homes
- Settled builder-grade fiberglass to R-19 or less. The original R-30 blown fiberglass in your 2005-2015 Cibolo home has compacted. It still looks like insulation. It’s not performing like insulation. A simple depth check - we do this free - reveals the gap between sticker rating and reality.
- Buried or missing attic baffles blocking soffit intake. Original construction crews in Cibolo’s rapid-build era often skipped baffles or knocked them loose. New insulation gets blown straight to the eaves. The attic bakes. Your compressor runs constantly. This is fixable in one trip.
- Zero air sealing at top plates and penetrations. Stack effect pulls conditioned air through every gap in the attic floor. Fresh R-value gets bypassed entirely. We seal first, then insulate - in that order, always.
- Wind-washed insulation around bath fans and HVAC penetrations. Cibolo’s attic turbulence from inadequate ventilation moves loose fiberglass away from critical junctions. We find bare drywall around fans routinely. We fix the air sealing, then replace the displaced material.

FAQs - Attic Insulation in Cibolo
You probably don’t. In Bentwood Ranch and Cibolo Crossing, we routinely measure original blown fiberglass at 6 inches or less - effective R-19, not the R-30 on the builder’s spec sheet. We offer a free attic depth check. Takes ten minutes. No obligation. Call (830) 243-6352 to schedule.
Your neighbor may have already topped up or replaced their attic insulation, or their home may have been built with better initial air sealing. Cibolo’s post-2000 tract homes were built to minimum code during a period of explosive growth, and that code allowed more thermal bypass than older, tighter construction. The “newer is better” assumption is exactly what’s costing you money. We can show you the blower-door numbers.
Yes. Uri exposed how poorly minimum-code attic insulation performs when outdoor temperatures drop below 10°F. Cibolo homes lost heat fast, and in some cases, pipes in attic chases froze because conditioned air wasn’t staying conditioned. The same under-insulated attics that bake your compressor in July will fail you again in the next hard freeze. Upgrading now addresses both extremes.
We typically use Owens Corning AttiCat blown fiberglass for Cibolo top-ups - it maintains loft in high-heat attics and matches well with existing material. Johns Manville or Knauf alternatives are available if your original insulation is one of those brands. We don’t push proprietary products. The scope specifies what you’ll get, by manufacturer and R-value target, before anyone starts. Call (830) 243-6352 for a written quote with material details.
One visit for standard top-ups, replacements, and air-sealing jobs. We bring materials, equipment, and crew sized for completion. The only exceptions are rare: if we discover active roof leaks or extensive rodent damage requiring remediation before insulation can go in, we’ll document it with photos, show you, and quote the additional work - but we don’t leave jobs half-finished for scheduling convenience. Haven Standard: Have it in writing, finish what you start.
