We’ve worked in enough Scenic Oaks attics to know the pattern. Homes built between the mid-1980s and mid-2000s, clustered off Scenic Loop Road and near the Hill Country State Natural Area access roads, carry the same legacy: R-19 fiberglass batts that have settled and degraded, no radiant barrier under the roof deck, and vaulted or cathedral ceiling geometries that make standard top-ups fail if air-sealing is skipped. The limestone terrain and 1,100-foot elevation here intensify both summer radiant heat and winter freeze risk beyond what flat-city San Antonio experiences. That dual-season load is why we treat air-sealing as mandatory, not optional, on every Blown-In Insulation job we take in this market.

Our Blown-In Insulation Services in Scenic Oaks
Blown-In Cellulose
We use cellulose from GreenFiber and Johns Manville for most Scenic Oaks attic jobs. Cellulose handles the Hill Country’s humidity cycles better than older fiberglass products, and at R-3.2 to R-3.8 per inch, it packs density into the irregular cavities around vaulted ceiling transitions where batts leave gaps. A full cellulose attic fill in a typical 2,200-square-foot Scenic Oaks home runs $3,200-$5,400 including air-sealing of top plates, can lights, and wire penetrations. We never blow insulation over an unsealed attic floor - that’s Haven Standard, not an upsell.
Blown-In Fiberglass
For homeowners who prefer fiberglass, we source Knauf and CertainTeed loose-fill products. Blown-in fiberglass works well in Scenic Oaks homes with straightforward, flat attic geometries where thermal bridging is minimal. It runs slightly cheaper per square foot - $1.80-$2.80 - but we flag this honestly: in vaulted-ceiling attics with skipped radiant barriers, fiberglass alone won’t stop the radiant heat gain that’s cooking your top-floor rooms. We pair it with air-sealing and, where budget allows, radiant barrier retrofit.
Dense-Pack Wall Insulation
Scenic Oaks’s 1990s slab-foundation homes often have empty stud cavities or poorly insulated exterior walls, especially on north-facing exposures that took the brunt of Winter Storm Uri. Dense-pack cellulose, blown at 3.5 pounds per cubic foot, fills these cavities without removing drywall. Most Scenic Oaks wall jobs run $2.80-$4.50 per square foot of wall area. This is the service that kept pipes from bursting in the homes that had it during the 2021 freeze - and the one most missing from the original build spec.
Blown-In Top-Up
The most common call we get in Scenic Oaks: “My attic has insulation, but my upstairs won’t cool.” We find R-19 batts compressed to R-12 or worse, settled away from vaulted edges, with no air-sealing and no radiant barrier. A top-up to R-38 with blown-in cellulose, after mandatory air-sealing, runs $2,400-$4,200 for most homes in the area. The field vignette we see repeatedly: a homeowner near the Edwards Plateau edge called after their vaulted-ceiling attic hit 150°F in July despite original R-19 batts. Our crew found heat gain through the roof deck because the original builder installed no radiant barrier. We topped up to R-38 with blown-in cellulose after air-sealing the complex vaulted geometry. During the next freeze event, that same air-sealing and top-up kept their pipes from bursting. The inadequate wall and attic insulation they’d lived with for decades was the real culprit, not the age of their HVAC unit.

Before
AfterTrusted Brands We Service in Scenic Oaks
We stock Johns Manville, Knauf, and CertainTeed materials for Scenic Oaks jobs, with no proprietary lock-in that forces a product choice you didn’t make. Our crews carry dense-pack cellulose, loose-fill fiberglass, and hybrid system components on every truck dispatched to the Hill Country. That local inventory means we don’t burn a day waiting for delivery from San Antonio - the job starts when we arrive, and the written price doesn’t shift because a SKU was back-ordered. Rockwool is available for fire-rated or high-temperature applications where code or homeowner preference demands it.
Common Blown-In Insulation Problems We See in Scenic Oaks Homes
- Original R-19 fiberglass batts in vaulted or cathedral ceiling attics degrade and settle over decades, leaving high-angle roof-deck areas severely under-insulated for Hill Country summers. We’ve measured attic floor temperatures of 140°F+ in these spaces while the homeowner’s thermostat reads 78°F downstairs.
- Builders of mid-1980s to mid-2000s Scenic Oaks homes omitted radiant barriers, so intense sun on limestone terrain drives attic heat gain that overwhelms the existing insulation long before the blown-in top-up itself is blamed. Homeowners replace HVAC systems first, then call us second.
- Slab-foundation homes with complex attic geometries create thermal bridging at vaulted transitions where standard blown-in upgrades can leave gaps if air-sealing is skipped. The blower-door test reveals what visual inspection misses: conditioned air streaming into the attic through unsealed top plates.
- Wall cavities in 1990s-era homes were often left empty or minimally insulated, exposing plumbing runs to freeze risk that attic insulation alone won’t address. Dense-pack wall work is the fix most homeowners don’t know they need until we show them the thermal camera image.

FAQs - Blown-In Insulation in Scenic Oaks
Yes. We won’t perform a top-up without it. The complex attic geometry in vaulted-ceiling homes creates thermal bridging at roof-plane intersections, and unsealed top plates allow conditioned air to escape directly into the attic. Our blower-door test measures this leakage in CFM50 - a single number that shows exactly how much air your building envelope is losing - and we seal before we insulate so the new material actually performs.
Mid-1980s to mid-2000s Hill Country tract builders skipped radiant barriers as a standard cost-saving measure, and current CPS Energy rebate programs now target their addition. It matters enormously: without a radiant barrier, roof deck temperatures in Scenic Oaks can exceed 160°F, radiating heat downward through any insulation type. Blown-in insulation slows conductive heat transfer but doesn’t block radiant heat. We address this with air-sealing first, then insulation, and discuss radiant barrier retrofit where the budget allows. Call (737) 227-6219 for an exact quote - estimates are free.
Attic insulation alone will not protect pipes in uninsulated exterior walls. Winter Storm Uri exposed the gap in 1990s Scenic Oaks builds: slab foundations with minimal wall insulation and R-19 attics that had settled to ineffective levels. We recommend dense-pack wall insulation for plumbing walls, combined with attic air-sealing and top-up, to create a complete thermal envelope. The documented blower-door numbers from our completed jobs show the difference - and the homeowners who had full envelope work done before Uri had a very different experience than those who didn’t.
Current Texas energy code and CPS Energy rebate programs target R-38 to R-60 for attics in this climate zone. The original R-19 in your Scenic Oaks home was designed for cooling-load-only thinking and has likely settled to R-12 or lower. We specify R-38 as our minimum for blown-in top-ups, with R-49 to R-60 for homeowners planning long-term occupancy or seeking maximum rebate capture. The written scope we deliver before work starts specifies exactly what R-value you’ll receive and where.
Scenic Oaks sits 1,100+ feet up on the Edwards Plateau, with more pronounced freeze risk, limestone terrain that intensifies radiant heat, and a housing stock built almost entirely around cooling loads with skipped radiant barriers and complex vaulted geometries. San Antonio’s flatter, older neighborhoods have different failure modes - balloon framing, pier-and-beam foundations, different code eras. The air-sealing-first approach matters everywhere, but the specific thermal bridging patterns and missing radiant barriers we find in Scenic Oaks make the pre-work inspection more critical here. Call (737) 227-6219 and we’ll show you what your attic actually looks like.
