Why Topside Attic Insulation Seguin Is New Braunfels’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our recent work has been in New Braunfels’s northern and western subdivisions - the tract homes built fast during the 2016-2022 boom. Our Attic Insulation in New Braunfels crews know what to look for in these houses: radiant barrier sheathing hiding thin blown fiberglass, top-plate bypasses leaking stack-effect air, and recessed-can penetrations that were never sealed at the ceiling plane.
Homeowners in New Braunfels leave reviews mentioning our blower-door numbers specifically - the before-and-after pressurization readings that show, in one figure, how much conditioned air their home was losing. Our 365-Day Done Right Promise applies to every job, backed by a written scope and written warranty delivered before work starts. Calls are answered by a live person 24/7, and our background-checked, uniformed technicians send a text when they’re on the way. We don’t do callback windows measured in business days.
Our Attic Insulation Services in New Braunfels
Blown-In Attic Insulation
We blow Owens Corning and GreenFiber fiberglass in New Braunfels attics, but only after we’ve sealed the envelope. Our Attic Insulation team starts with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - then air-seals top plates, can lights, and penetrations before the insulation machine fires up. In New Braunfels’s 140°F July attics, unsealed bypasses make blown fiberglass perform like a sieve. We don’t blow over leaks.
Attic Batt Insulation
Batt insulation still has a place in New Braunfels’s older stock - the pre-1960s German limestone-masonry homes near downtown and Gruene with irregular joist bays and limited attic access. We cut batts to fit without compression gaps, which is harder than it sounds in a 90-year-old rafter bay. Every batt job gets the same air-sealing protocol as our blown work, and we document the installation with photos you’ll receive before we leave.
Attic Insulation Top-Up
This is our most common call in New Braunfels. Production builders during the 2016-2022 surge installed roughly R-30 to R-38 of blown fiberglass that has settled to R-28 or lower, and homeowners notice the difference in their summer electric bills. We don’t just add inches. We pull back the existing insulation, seal what the builder skipped, install baffles where truss chords have choked eave intake, then blow to R-49. The result is documented with before-and-after blower-door numbers and a photo record.
Attic Insulation Replacement
When insulation is contaminated, water-damaged, or installed so poorly that topping up won’t fix it, we remove and replace. In New Braunfels, we see this most often in homes where the original blown fiberglass was installed over unsealed can lights that leaked for years, or where roof leaks from Hill Country hail events saturated the cavity. We remove the compromised material, remediate the substrate, seal the envelope, and reinstall to R-49 with full documentation.
Attic Baffles & Ventilation Prep
New Braunfels production attics are tight. Truss chords pinch eave intake, builders crush baffles or skip them entirely, and ventilation short-cycles hot air back into the cavity. We prep baffles and ventilation before any insulation goes in, ensuring soffit intake reaches the ridge vent without blowing insulation into the airflow path. This step is non-negotiable under our Haven Standard - sealed first, then insulated, in that order.

Before
AfterTrusted Brands We Service in New Braunfels
We source materials from Owens Corning, GreenFiber, Icynene, and Demilec, among others - no proprietary product lock-in means we specify what performs for your specific attic, not what moves our inventory. For New Braunfels’s high-heat attics, we typically specify Owens Corning blown fiberglass for its dimensional stability above 140°F, or Icynene open-cell spray foam where air-sealing value is paramount and the budget allows. We stock common materials locally for fast turnaround, and every product is documented in your written scope before work begins.
Common Attic Insulation Problems We See in New Braunfels Homes
- Unsealed top-plate bypasses behind thin blown fiberglass. Production builders in Veramendi and along FM 306 left 2- to 4-inch gaps at the top of wall plates, leaking stack-effect air straight into conditioned space. In New Braunfels’s 140°F attic cavities, that’s not a minor leak - it’s a direct thermal bridge that shows up on your CPS bill every July.
- Radiant barrier sheathing substituting for real R-value. The roof deck reads low-emissivity, but the ceiling assembly still underperforms. Radiant barriers help, but they don’t replace insulation. We measure actual R-value at the ceiling plane, not the roof deck.
- Crushed or omitted wall baffles in tight production attics. Where truss chords choke eave intake, ventilation short-cycles and blown insulation drifts and settles unevenly. We find lopsided R-value across the same attic floor - thick near the hatch, thin at the eaves where it’s needed most.
- Recessed-can penetrations completely unsealed. IC-rated or not, can lights are holes in your ceiling. In New Braunfels’s slab-on-grade homes, where all insulation opportunity is concentrated in the attic plane, each unsealed can is a direct path for 140°F air to pressurize your ceiling assembly.
Pricing for Attic Insulation in New Braunfels, TX
A typical attic air-seal and blow in New Braunfels runs $1,800 to $3,400 for homes under 2,500 square feet, and $3,200 to $4,200 for larger homes or those requiring extensive top-plate and can-light sealing. Attic insulation top-up with air-sealing prep runs $1,200 to $2,800. Full removal and replacement starts around $2,800 and scales with contamination level and attic square footage. Attic baffles and ventilation prep add $400 to $800 depending on linear footage of eave and the condition of existing intake.
What moves the number: attic square footage, existing insulation condition, accessibility (some New Braunfels production attics have hatches too small for a technician with a hose), and the extent of air-sealing required. We provide a written price before any work starts - Haven Standard Clause 1 - and a free second opinion on any competing written estimate. Call (830) 549-6646 for your exact number.

FAQs - Attic Insulation in New Braunfels
Because the R-38 rating is on paper, not in performance. Production builders hit code by pairing radiant barrier sheathing with thin blown fiberglass, but left top-plate bypasses and recessed-can penetrations completely unsealed. At 140°F attic temperature, those leaks dominate thermal comfort more than the nominal R-value. We air-seal first, then verify with a blower-door test. Call (830) 549-6646 for a free estimate - we’ll show you the actual leakage number.
Top-up is sufficient if the existing insulation is clean, dry, and was installed over a sealed envelope - rare in 2016-2022 production homes. We pull back a test section during our estimate. If we find unsealed top plates or can lights, we recommend air-sealing prep plus top-up to R-49. Full replacement is only necessary for contaminated, water-damaged, or severely settled material. Written scope, written price, no exceptions.
Yes. The same Hill Country geography that bakes attics at 140°F in July channels Blue Norther fronts that drop temperatures 40°F in hours. An attic that leaks in summer leaks in winter - just in reverse, pulling heated air out. We design for year-round performance, not just peak summer, because Winter Storm Uri proved that under-insulated New Braunfels homes lose heat as fast as they gain it. Blower-door verification confirms the envelope works both directions.
Because tight truss chords in these attics crush or omit baffles, and without proper soffit-to-ridge airflow, ventilation short-cycles and insulation drifts. We’ve found lopsided R-value in attics where the builder skipped this step - thick near the hatch, bare at the eaves. Under Haven Standard, we don’t blow over a ventilation problem. Baffles go in first, then insulation, then documentation.
Yes. These homes have irregular joist bays, limited attic access, and often no insulation at all in the original construction. We cut batts to fit without compression, or use dense-pack techniques where access allows. Every job still gets the full air-sealing protocol and documented photo record. Call (830) 549-6646 - we’ll assess access and give you a written price before any work starts.
