Fast, Reliable Blown-In Insulation Across Bulverde
Blown-in insulation in Bulverde typically runs $1.80-$3.20 per square foot installed, with most attic top-ups or full replacements completed in a single day. If your home sits along TX-46 or Bulverde Road in one of the master-planned communities built during the 2010s and early 2020s, the original blown fiberglass has likely settled below its rated R-38 under our Hill Country heat.

We’re the Blown-In Insulation team at Topside Attic Insulation New Braunfels, and we serve Bulverde from our Dallas-Fort Worth dispatch office with crews that work this corridor weekly. Bulverde’s newer homes present a specific problem: builders met minimum Texas energy code, but they didn’t account for 150°F+ attic temperatures on exposed hilltops or the hard freezes that roll down from the Balcones Escarpment. We’ve sealed and insulated more than 9,000 homes since 2016, and the documentation we deliver - written scope, blower-door numbers when applicable, and a photo record - is the same whether we’re in Bulverde, Canyon Lake, or Cibolo.
Why Topside Attic Insulation New Braunfels Is Bulverde’s Preferred Blown-In Insulation Company
Our reputation in Bulverde comes from working the same housing stock repeatedly: the 8-12-year-old tract homes in Johnson Ranch, Bulverde Ranch, and the communities north of TX-46 where blown fiberglass has settled unevenly and ridge vents have crushed under thermal cycling. Homeowners here leave reviews mentioning the blower-door printout we leave behind, not vague promises about “efficiency.” They read three-star reviews as carefully as five-star ones, so we publish the numbers.
Response time to Bulverde is typically same-day or next-day, depending on whether we’re running a crew through the corridor that day. Calls are answered by a live person 24/7, and you’ll get a text when your technician is en route - Haven Standard: Arrive on schedule, named technician, no callback windows measured in business days.
We know the local failure modes because we’ve pulled attic hatches in these exact homes. The builder-grade ridge venting on hilltop exposures. The unsealed top plates over garages. The blown fiberglass that reads “new construction” but performs like it’s twenty years old. That local knowledge changes what we recommend and how we price it.
Our Blown-In Insulation Services in Bulverde
Blown-In Fiberglass
This is what most Bulverde attics started with, and it’s often what they still need - just installed correctly this time. We source Owens Corning and Johns Manville fiberglass, blow it to true depth (not the thin, settled layer your builder left), and we don’t blow it until the attic floor is sealed. In Bulverde’s vented attics, that means air-sealing can lights, top plates, and penetrations first. Otherwise you’re paying for R-38 performance and getting R-28 in practice.
Blown-In Cellulose
For Bulverde homeowners who want a denser fill with better sound dampening, we blow GreenFiber cellulose to the same depths. Cellulose settles less than fiberglass under our extreme attic heat, which matters on these exposed hilltops. We still seal first. Still document with photos. Still give you the written price before the truck rolls.
Blown-In Top-Up
This is our most common call in Bulverde. The original blown fiberglass in your 2015-2022 home has settled to 9-11 inches, creating thin spots over the garage, vaulted sections, and anywhere the installer walked the joists during rough-in. A blown-in top-up brings the assembly back to true R-38 without the cost of full removal. Most Bulverde top-ups run $1,800-$3,400 for a typical 2,400-square-foot home, depending on access and how much air sealing the top plates need.
Dense-Pack Wall Insulation
Bulverde’s slab-on-grade tract homes often have empty or poorly filled exterior wall cavities, especially where the builder used minimum-code batt insulation that sagged or was compressed by electricians during rough-in. Dense-pack cellulose or fiberglass - blown at high pressure into closed cavities - fills those gaps without opening drywall. It’s a standard upgrade for homeowners who felt their walls go cold during February 2021’s freeze and don’t want a repeat.

Before
AfterTrusted Brands We Service in Bulverde
We stock Owens Corning, Johns Manville, and Knauf blown fiberglass and batts for Bulverde jobs, with no proprietary lock-in that forces one product on every home. If your original insulation was CertainTeed or Rockwool, we match or upgrade with what’s actually appropriate for your assembly. Materials arrive with the crew, not on a separate freight timeline, so we’re not burning a day waiting for stock while your attic hatch hangs open. The brand matters less than the installation quality and the air sealing that precedes it, but we name what we use because you’ll find it in the photo record we leave behind.
Common Blown-In Insulation Problems We See in Bulverde Homes
- Uneven settling in 150°F+ attics. The blown fiberglass in your 2018-built home off Bulverde Road has likely settled to an inconsistent depth, with thin spots over the garage ceiling and anywhere the original installer compressed it with their boots. The hilltop exposure accelerates this.
- Undersized ridge venting on exposed hilltops. Builder-grade ridge vents that work fine in flat San Antonio subdivisions short-circuit in Bulverde’s wind exposure, letting hot air stagnate above your insulation and driving moisture cycling that crushes the vent itself.
- Unsealed top plates and garage ceiling junctions. Your home was built fast, and the gap between the wall top plate and drywall was never sealed. Conditioned air leaks out, attic air leaks in, and your R-38 performs like R-28 no matter what the label says.
- Heat loss during hard freezes. Minimum-code blown fiberglass sheds heat fast when temperatures drop below 20°F, which Bulverde saw during Winter Storm Uri. Homes with sealed assemblies and proper depth held steady; homes with settled, unsealed insulation did not.

These are installed prices for Bulverde’s market, including materials and labor.

FAQs - Blown-In Insulation in Bulverde
Your 2018 home was built to minimum Texas energy code with R-38 blown fiberglass, but the hilltop exposure above the Balcones Escarpment routinely pushes attic temperatures past 150°F, causing uneven settling and performance below the labeled R-value. We’ve pulled attic hatches in 6-year-old Bulverde homes where the insulation reads 9-10 inches in spots, not the 12+ inches required for true R-38. Call (830) 243-6352 for a free assessment - estimates are free, and you’ll get a written price before any work starts.
Yes, and we frequently do both on the same visit. We were called to a 2016-built home off Bulverde Road where the homeowner had already replaced two builder-grade garage door openers and still felt hot air pouring into the garage. Our crew pulled the attic hatch and found the original blown fiberglass settled to an uneven 9-10 inches with a crushed ridge vent, so we air-sealed the top plates, added blown fiberglass to bring the assembly back to a true R-38, and reset the ridge venting for the hilltop wind exposure. The homeowner paired it with a smart Wi-Fi opener upgrade, and the garage-to-house temperature delta dropped enough that the door hardware stopped cycling constantly.
Bulverde’s housing stock is almost entirely 8-12-year-old vented attics with failed ridge venting and settled blown fiberglass, making unvented conversion a standard upgrade rather than an exotic retrofit. In older San Antonio neighborhoods, you’re more likely to see decades-old insulation, asbestos concerns, or structural issues that complicate conversion. Here, it’s often a cleaner job: seal the floor, spray the roof deck, condition the attic. The 365-Day Done Right Promise applies either way.
We start with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - then photograph the attic condition and measure existing insulation depth. Homes that hemorrhaged heat during February 2021 almost always show unsealed top plates, settled blown fiberglass below R-38, and garage ceiling junctions that were never air-sealed at construction. We give you the before-and-after blower-door numbers so you can verify the fix, not just trust that it worked.
We install Owens Corning, Johns Manville, and Knauf blown fiberglass, plus GreenFiber cellulose, depending on your assembly and preference. No proprietary lock-in. The brand is documented in your photo record, along with the installed depth and coverage area. Call (830) 243-6352 if you want to discuss which material makes sense for your specific attic - estimates are free, and the written price comes before any work starts.
