Fast, Reliable Blown-In Insulation Across New Braunfels
Blown-in insulation in New Braunfels typically costs $1,800-$4,200 for attic work in a 2,000-square-foot production home, with most jobs completed in a single day. If your home was built between 2005 and 2020 in Veramendi, Meyer Ranch, or Hunter’s Creek, there’s a strong chance your original builder-grade insulation has already compressed well below its labeled R-value.
We’re the crew that serves New Braunfels from our San Antonio dispatch office, and we know this market. We’ve worked in the attics of enough homes off Loop 337 and along the Guadalupe River corridor to recognize the patterns: minimum-code insulation installed fast, air leaks never sealed, and homeowners left with electric bills that spike every July. Our technicians are background-checked, uniformed, and carry documented photo records on every visit. Call (830) 402-5240 and you’ll reach a live person, 24/7. No voicemail loops.
Why Topside Attic Insulation Schertz Is New Braunfels’s Preferred Blown-In Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of them sit in New Braunfels’s fast-growing corridor. Our reviews from New Braunfels customers consistently mention two things: the written price they received before anyone touched a tool, and the blower-door numbers they held in their hands when we left. That’s Haven Standard Clause 1. Flat price, written scope, written warranty before anyone lifts a tool.
Response time to New Braunfels runs same-day to next-day for standard calls, and we text you when your named technician is en route. We don’t use callback windows measured in business days.
Our local knowledge runs deeper than zip codes. We know which New Braunfels subdivisions used the thinnest batts, which valley-floor neighborhoods need vapor-barrier details the Hill Country skips, and why a Gruene limestone building can’t be treated like a wood-frame tract home. That specificity matters when you’re deciding whether to top up, dense-pack, or start over entirely.
Our Blown-In Insulation Services in New Braunfels
Blown-In Fiberglass
This is our most common request in New Braunfels, and for good reason. We blow Owens Corning and Johns Manville fiberglass to R-49 in production-home attics, replacing compressed builder-grade R-30 that has settled to R-15 or less after 8-10 years of thermal cycling. The material doesn’t absorb moisture, which matters in the Guadalupe River valley where humidity runs 10-15% higher than the Hill Country just west of I-35. We air-seal first - top plates, recessed lights, penetrations - then blow. Always in that order.
Blown-In Cellulose
For homeowners who want a higher recycled content and better sound dampening, we install GreenFiber cellulose treated with borate fire retardant. In New Braunfels’s newer subdivisions, cellulose performs well when the attic floor has been properly sealed first. We don’t blow it over unsealed air leaks. The Haven Standard doesn’t allow it.
Dense-Pack Wall Insulation
Production homes in communities like Veramendi and Hunter’s Creek often arrive with fiberglass batts in exterior walls that barely fill the cavity, leaving thermal bridges and air channels. We dense-pack walls with blown fiberglass or cellulose at 3.5 pounds per cubic foot, filling every gap. In river-corridor neighborhoods, we pay particular attention to moisture management; improper dense-pack without vapor-smart detailing has led to mold in wall cavities here, where valley humidity meets air-conditioned interiors.
Blown-In Top-Up
Not every attic needs a full removal. If your existing blown-in fiberglass is in decent shape but has settled below R-38, we can top up to R-49 after sealing accessible leaks. This is the most cost-effective path for New Braunfels homes in the 8-12 year range where insulation is thinning but not degraded. We give you a written price for both options - top-up versus full replacement - so you can decide with numbers in front of you.

Trusted Brands We Service in New Braunfels
We source materials from Owens Corning, Johns Manville, and GreenFiber, with no proprietary lock-in that limits your options. For New Braunfels customers, this means we stock common blown-in products locally and can match or upgrade what your builder originally installed without special-order delays. If your home was built with a specific brand and you want consistency, we can do that. If you want to switch based on performance data, we’ll show you the blower-door and thermal imaging that explains why.
Common Blown-In Insulation Problems We See in New Braunfels Homes
- Builder-grade fiberglass compressed to R-15 or less in Veramendi attics. The original R-30 batts or loose-fill were never dense enough to resist settling through a decade of 100°F summers and sudden Blue Norther temperature crashes. The result is attic air pouring through unsealed top plates and recessed lights into your living space.
- Historic Gruene and downtown limestone walls with zero insulation and no stud cavity. Standard blown-in methods don’t apply here. We’ve seen improper spray foam retrofits trap moisture in dense limestone, triggering efflorescence and spalling that damages the rock face. These buildings need specialized assessment.
- Dense-pack wall installs without moisture management in river-corridor homes. Along the Guadalupe and Comal, exterior wall cavities with poor vapor detailing accumulate humidity. The mold growth that follows is a failure mode we prevent by sealing the interior air barrier before packing the cavity.
- Original blown-in insulation past its effective life in 5-15 year production homes. New Braunfels’s building boom produced thousands of homes that are now hitting this window. The insulation hasn’t reached 30 years, but it has reached uselessness. Humidity and temperature swings here accelerate breakdown faster than drier climates.
Pricing for Blown-In Insulation in New Braunfels, TX
Most blown-in attic jobs in New Braunfels run $1,800-$4,200 for a 2,000-square-foot home, depending on current insulation condition and whether we remove or top up.

FAQs - Blown-In Insulation in New Braunfels
Your builder installed minimum-code R-30 insulation that has compressed to roughly R-15 after nine years of New Braunfels heat cycles and humidity. We recently worked in Veramendi on a 2015-built home where the homeowner’s first full Texas summer produced a shock $480 electric bill. We pulled the builder-grade fiberglass, air-sealed the top plates and recessed lights, and blew in Owens Corning fiberglass to R-49, trimming the attic temperature by 15°F and bringing the bill down to the $320 range. The homeowner, a transplant from Ohio, said the difference was like adding a second air conditioner. Call (830) 402-5240 for a free assessment of your attic’s current R-value.
No. Standard blown-in insulation requires a stud cavity, and Gruene’s 19th-century limestone walls have virtually none. The dense stone also has poor inherent thermal resistance. In these buildings, spray foam applied to the interior face of the rock is often the only viable retrofit, but it must be done with moisture-smart detailing to avoid trapping humidity and causing efflorescence or spalling. We assess these properties separately from our standard blown-in scope. Call us to discuss the specific building.
The Guadalupe and Comal river corridors create localized humidity 10-15% higher than the drier Hill Country just west of town. This matters because moisture reduces fiberglass’s effective R-value over time and can trigger mold in wall cavities where vapor barriers are missing or compromised. We address this by completing air sealing before any insulation goes in, and by specifying moisture-appropriate materials for river-corridor homes. Our before-and-after blower-door numbers document that the air barrier is performing before we close the job.
R-49 is the practical target for New Braunfels attics, given the combination of 98-103°F summer peaks and periodic severe cold fronts. The Department of Energy recommends R-38 to R-60 for this climate zone; we find R-49 hits the performance-per-dollar sweet spot for most local homes. If your current attic measures R-30 or less - common in production builds - you’re leaving measurable efficiency on the table. We’ll show you the thermal imaging that proves it.
For New Braunfels production homes built 2005-2020, we recommend an attic assessment at year 5-7, with action typically needed by year 8-12. The 5-15 year window is where we see peak failure: insulation compressed, air leaks never sealed, and electric bills climbing faster than utility rates. Don’t wait for the 30-year lifespan builders imply. The region’s humidity and temperature swings accelerate breakdown well before that. Call (830) 402-5240 and we’ll inspect your current depth and condition at no charge.
