Call (830) 402-5240 for a free written estimate with exact pricing before any work starts.
We’ve insulated attics in Veramendi, Meyer Ranch, Hunter’s Creek, and the Gruene historic district. New Braunfels isn’t one housing market - it’s two. The production-built homes going up since 2010 need one approach. The 19th-century limestone buildings downtown need another. We figure out which one you have before we load the truck, so we show up with the right material and the right crew and finish in one trip. No return visits for “oh, we didn’t know it was limestone.”
Why Topside Attic Insulation Schertz Is New Braunfels’s Preferred Attic Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a growing share of those are in New Braunfels as the city has expanded. Our reviews from New Braunfels customers consistently mention the same thing: we named the price upfront, showed the blower-door numbers after, and didn’t try to sell insulation over unsealed air leaks.
Response time matters here. New Braunfels covers a lot of ground - from the compact lots in the original city grid to acreage off FM 306 and River Road with 400-foot drives. We schedule accordingly. Our crews carry enough material variety to handle either a 1,200-square-foot production attic or a detached workshop on a rural property without driving back to the warehouse.
Local knowledge that saves money: we know which New Braunfels subdivisions were built during the 2011-2016 code window when Texas allowed R-30 as “minimum” attic insulation. Those homes are now 8-14 years old. The fiberglass has settled. The R-value has dropped. We find this on roughly half our New Braunfels inspections, and we document it with photos you can see before we quote the fix.
Our Attic Insulation Services in New Braunfels

Blown-In Attic Insulation
Blown-in fiberglass or cellulose is what most New Braunfels production homes need. We use Owens Corning fiberglass and GreenFiber cellulose, depending on your roof geometry and whether you have active soffit ventilation that needs baffles. In neighborhoods like Veramendi and Hunter’s Creek, we regularly find original blown-in that has compressed from its labeled R-30 down to an effective R-18 or R-20. We remove the settled material, seal the attic floor properly, then blow fresh insulation to R-38 or R-49 - the depth your builder should have installed in the first place.

Attic Batt Insulation
Batt insulation still has a place in New Braunfels, mainly for knee walls, bonus-room ceilings, and attic hatches where blown-in won’t stay put. We use Johns Manville and Owens Corning batts cut to fit, not stuffed into place. Poorly installed batts are what we find most often in 2010s-era New Braunfels builds - compressed at the eaves, gaps around top plates, vapor barrier facing the wrong direction. We correct the installation errors before adding anything new.

Attic Insulation Top-Up
If your existing insulation is in decent shape but shallow, a top-up can be the most cost-effective option. In New Braunfels, this works when the original material hasn’t been disturbed by rodents, water, or remodeling traffic. We inspect first. If we find the insulation is compressed but clean, we add blown-in fiberglass on top to reach R-38 or R-49. If we find air leaks or moisture staining, we quote the full removal and replacement - no point in burying a problem. Our Attic Insulation team will tell you which category you’re in before you commit.

Attic Insulation Replacement
Full replacement is common in New Braunfels homes that have had roof leaks, rodent activity, or simply 15+ years of settled insulation. We remove the old material, dispose of it, seal all penetrations, install baffles at the soffits, and blow new insulation to spec. The entire job is photographed, and on applicable jobs we run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope was losing before and after the work.

Attic Baffles & Ventilation Prep
New Braunfels’s combination of summer heat and river-corridor humidity makes ventilation details critical. Baffles keep soffit intake air flowing over the insulation rather than pushing it back from the eaves. Without them, you get wind-washing, which reduces R-value, and in humid valley-floor neighborhoods near the Guadalupe or Comal, you can get moisture accumulation against the roof deck. We install proper cardboard or foam baffles before blowing insulation, and we verify that exhaust vents (ridge, gable, or powered) are actually drawing. A vent that looks open but is blocked by paint or wasp nests is a vent that isn’t working.

Trusted Brands We Service in New Braunfels
We stock Owens Corning fiberglass, GreenFiber cellulose, and Icynene open-cell spray foam on our New Braunfels-bound trucks. No proprietary lock-in, no “only one brand we push.” If your home needs spray foam for a Gruene limestone retrofit, we carry Icynene and can source Demilec for closed-cell applications where moisture management is critical. Having material on hand means we don’t quote one thing and return three days later with something else. The brand choice is based on your building, not our warehouse.
Common Attic Insulation Problems We See in New Braunfels Homes

- Settled blown-in in production homes. The fast-growth subdivisions like Veramendi and Meyer Ranch were insulated to minimum code with fiberglass batts or thin blown-in. After 5-15 years, that material has compressed enough that the labeled R-value is fiction. We measure actual depth and quote based on what you have, not what the builder claimed.
- Humidity damage in river-corridor neighborhoods. Valley-floor areas near the Guadalupe and Comal carry higher humidity than the Hill Country just west. Attic installs without proper vapor management can trap moisture against the decking. We see this as stained plywood, corroded nail heads, or early shingle failure. Our installs include vapor-barrier assessment as standard.
- Limestone buildings with no insulation path. In Gruene and the historic district, old limestone exterior walls were never insulated and have no stud cavity. Any attempt to retrofit with batts or blown-in leaves thermal bridging and can trap moisture in the stone. We use interior spray foam applied directly to the rock face, carefully specified to avoid efflorescence or spalling - a failure mode you don’t see in wood-frame neighborhoods.
- Disconnected or missing baffles. Even in newer New Braunfels homes, we find baffles that were never installed, fell out, or got crushed during roofing work. The result is insulation blocking soffit vents, which kills airflow and creates hot spots. We check this on every inspection and install proper baffles before adding any new material.

FAQs - Attic Insulation in New Braunfels

Because R-30 was the Texas minimum code during the 2011-2016 construction wave, and that fiberglass has settled and compressed to an effective R-18-R-20 by now. New Braunfels’s position at the Balcones Escarpment means you face both 100°F summer days and sudden 40-degree temperature drops from Blue Norther fronts - your insulation needs to perform at both extremes, and settled R-30 doesn’t. We measure actual depth during inspection and quote to restore true R-38 or R-49. Call (830) 402-5240 for a free estimate.
No. Gruene limestone buildings have no stud cavity and no attic space in the conventional sense. Blown-in or batt insulation has nowhere to go and would trap moisture against the stone. We use interior spray foam applied directly to the rock face, specified to allow vapor permeability and prevent efflorescence or spalling. Meyer Ranch production homes are standard wood-frame attics - blown-in fiberglass to R-49 after air sealing. Two different buildings, two different scopes, and we determine which before we arrive. Call (830) 402-5240 to discuss your specific home.
Yes. Valley-floor neighborhoods in New Braunfels carry higher ambient humidity than the drier Hill Country to the west. Without proper vapor-barrier details and ventilation balance, warm moist air can reach the roof deck and condense. We assess your existing ventilation path - soffit intake, exhaust flow - and specify baffles and vapor management appropriate to your microclimate. This is standard on our New Braunfels jobs, not an add-on. Call (830) 402-5240 to schedule an inspection.
We ask about access during scheduling. If you have a 300-foot gravel drive off River Road or a detached shop that needs its own insulation, we load the truck accordingly - extra hose length, additional material, the right crew size. Our field vignette: a Meyer Ranch homeowner called after a July electric bill doubled what they paid in their previous state. We found 8 inches of settled blown-in, removed it, sealed top plates and can lights, baffled soffits, and blew Owens Corning to R-49 - all in one trip with no return visit needed. That’s the standard we plan for. Call (830) 402-5240 to schedule.
We inspect and clear soffit vents, install baffles to maintain airflow from eave to ridge, verify exhaust vent function, and check for blocked or painted-over openings. In New Braunfels’s river-humidity environment, this step prevents moisture accumulation that can rot decking or degrade shingles. The prep is photographed and included in your documented photo record. Ventilation prep adds $600-$1,200 to a typical job but is essential for performance and warranty coverage. Call (830) 402-5240 for specifics on your attic.
