We’ve been sealing and insulating homes in Bulverde’s subdivisions since the first wave of post-2000 development, and we’ve documented the same pattern enough times to know it by address range: builder-grade R-30 blown fiberglass in a 3,500-square-foot attic with minimal air sealing at the top plates. It meets code on paper. It doesn’t perform in a February freeze.

Our Blown-In Insulation Services in Bulverde
Blown-In Fiberglass
We blow Owens Corning and Johns Manville fiberglass in Bulverde attics, typically upgrading builder-grade R-30 fields to R-49 or R-60 depending on the accessible depth and framing configuration. Fiberglass doesn’t settle as aggressively as cellulose, which matters in Bulverde’s steep-pitch attics where crews are working at angles and uniform depth is harder to achieve. Every job starts with a written price and ends with a Documented Photo Record.
Blown-In Cellulose
Cellulose - treated ground paper with borate fire retardant - packs tighter at a given R-value and performs better against air movement when dense-packed. In Bulverde’s older pre-2000 stock or in homes where homeowners want a recycled-content material, we specify GreenFiber or similar borate-treated products. We still air-seal first. We always air-seal first.
Blown-In Top-Up
This is the service we perform most often in Bulverde: the existing blown fiberglass has settled to R-20 or below, the attic floor shows thin spots and high points, and the homeowner wants to know whether to remove it or blow over it. If the existing material is dry, uncontaminated, and not compressed by storage or foot traffic, we air-seal the penetrations and top plates, then blow new Owens Corning or Knauf fiberglass across the field to achieve uniform R-49 or R-60. It’s less expensive than full removal. It works if the substrate is sound.
Dense-Pack Wall Insulation
Here’s where Bulverde’s building stock gets specific. That stone veneer on your Hill Country-style home - the one that looks like solid masonry - is typically a 1-inch non-structural façade over OSB sheathing with no continuous exterior insulation. Thermal bridging through the dense stud framing bleeds heat in January and bleeds cool air in July. A dense-pack wall insulation job, using blown cellulose or fiberglass packed to 3.5 pounds per cubic foot in the stud cavities, doesn’t eliminate thermal bridging but it reduces the air movement that makes it worse. We tell Bulverde homeowners the truth: attic blow-in alone won’t fix the wall assembly. Dense-pack is the next step.
Our Blown-In Insulation team documents every wall cavity with photos before and after.

AfterTrusted Brands We Service in Bulverde
We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, no house brand you can’t cross-reference. For Bulverde jobs, we stock Owens Corning L77 loose-fill fiberglass and Knauf Jet Stream Ultra on the truck, which means most attic top-ups and full fills don’t wait on a supplier run to San Antonio. If your home needs a specific product for warranty continuity or compatibility with existing material, we order it and schedule accordingly. The written scope specifies exactly what goes in; you verify it against the bags left on site.
Common Blown-In Insulation Problems We See in Bulverde Homes
- Settled builder-grade R-30 in expansive attics. The blown fiberglass in Bulverde’s 2,500-4,500 sq ft homes was installed to a labeled R-30 depth but has settled unevenly over 5-15 years, leaving cold spots above bedrooms and pushing July attic temperatures past 150°F in the thin zones.
- Minimal air sealing at top plates and recessed lights. Builder packages in Bulverde’s 2000s-2020s subdivides rarely include thorough sealing of the attic floor plane. Hill Country freeze air infiltrates through these gaps, which is exactly what contributed to pipe failures during Winter Storm Uri while better-sealed neighbors kept water flowing.
- Thermal bridging through stone-veneer wall assemblies. The 1-inch non-structural stone over OSB with no continuous exterior insulation creates a heat-loss path that attic insulation alone cannot address. Homeowners who top up the attic and see no bill improvement are usually looking at this wall problem.
- Compressed or disturbed existing insulation. Bulverde’s large-footprint homes often have attic storage platforms, HVAC service paths, or homeowner traffic that compresses blown fiberglass to a fraction of its rated R-value. Compressed fiberglass doesn’t recover.

FAQs - Blown-In Insulation in Bulverde
Your attic likely had the standard builder package: R-30 blown fiberglass with minimal air sealing at top plates and recessed lights, installed in a home at 1,100-1,400 feet elevation where freeze events hit harder than in San Antonio 25 miles south. The unsealed attic floor let cold Hill Country air infiltrate continuously, and the R-30 material - often settled below its labeled depth by 2021 - couldn’t maintain enough thermal boundary to protect the plumbing penetrations. Your neighbor may have had better air sealing, a higher R-value, or both. Call (737) 227-6219 and we’ll blower-door test to show you the exact air-loss number.
Yes, if the existing insulation is dry and uncompressed and if we air-seal first. A proper top-up to R-49 or R-60 with sealed penetrations typically reduces cooling load enough to show on the bill, especially in Bulverde’s 150°F attic summers. If your walls have the common stone-veneer-over-OSB thermal bridging problem, the attic improvement will be partial - you’ll see some reduction, but not the full potential until the wall assembly is addressed. We document the before-and-after blower-door reading so you can verify the air-sealing result yourself.
It affects what you should expect. That stone is typically a 1-inch non-structural façade over OSB with no continuous exterior insulation, so heat bleeds through the dense stud framing in a pattern that attic blow-in cannot stop. We recommend dense-pack wall insulation as the complementary step. We tell Bulverde homeowners this before we price the attic, not after. No surprises. Written scope. Haven Standard.
R-49 to R-60 for attics, per IECC climate zone 2 with the Hill Country elevation adjustment for freeze exposure. Builder-grade R-30 was code-minimum for the era most Bulverde homes were built, but it underperforms in actual conditions here. We specify the target R-value in the written scope and verify installed depth with a ruler before we leave. Photos included.
If it’s dry, uncontaminated, and not compressed by storage or foot traffic, we air-seal and top up. Removal is only necessary for mold, rodent contamination, or severe compression that won’t recover. We inspect and photograph the existing field during the estimate, then specify in the written scope whether we’re topping up or removing. You see the photos. You sign the scope. Then we start.
