Fast, Reliable Attic Insulation Across New Braunfels
Most attic insulation jobs in New Braunfels run $1,800-$4,200 depending on square footage and whether air sealing is needed first, and our crews typically book within 48 hours for standard work. We dispatch from our San Antonio office and run trucks to New Braunfels daily, so you’re not waiting on a crew driving up from San Marcos or down from Austin. Call (830) 243-6352 for a written price before anyone sets foot in your attic - that’s Haven Standard Clause 1, and we don’t bend it.
We’ve worked in enough Veramendi and Hunter’s Crossing attics to know the pattern: fiberglass blown to full depth at the hatch, then thinned to almost nothing over exterior walls and can lights. Your builder wasn’t trying to cheat you personally. The crew was just racing the schedule that New Braunfels’s growth curve demanded. We fix that.
Why Topside Attic Insulation New Braunfels 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 right here in New Braunfels - from the 1970s ranch homes near Gruene to the 2019 builds still settling along FM 306. Our reviews from New Braunfels customers consistently mention two things: the blower-door numbers we leave behind, and the fact that we actually show up when we said we would. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
Response time to New Braunfels is typically same-day or next-day for assessments, and we carry GreenFiber, Owens Corning, and Johns Manville materials on our trucks so we’re not ordering stock after we see your attic. Our technicians are background-checked and uniformed, and when you call (830) 243-6352, a live person answers - no voicemail loop, no “we’ll call you back between 8 and 5.”
The local knowledge that matters here is specific. We know which New Braunfels subdivisions used which builder, which years had the thinnest installs, and where the Balcones Escarpment wind patterns drive attic moisture differently than flatland Comal County. That matters when we’re deciding between a top-up and a full replacement, or whether your baffles are worth saving.
Our Attic Insulation Services in New Braunfels

Blown-In Attic Insulation
We blow cellulose and fiberglass to uniform depth across the entire attic field, not just the easy spots near the hatch. In New Braunfels’s post-2010 subdivisions, this usually means correcting the speed-cut installs we find in Veramendi, Elm Creek, and along FM 1101 - full depth at the access, thin over exterior walls. We air-seal first, then insulate. Always. Our Attic Insulation team uses GreenFiber cellulose or Owens Corning fiberglass depending on your roof pitch and moisture risk.

Attic Batt Insulation
Batt fits certain New Braunfels attic geometries better than blown - especially the shallow-pitch ranch homes from the 1980s near Gruene, where blown material would drift with every HVAC vibration. We cut batts to fit around trusses and top plates without compression gaps, and we document the install with photos you keep. Most batt jobs in New Braunfels run $2,200-$3,800 for a 2,000-square-foot home.

Attic Insulation Top-Up
This is our most common call in New Braunfels. Your builder hit R-30 at the hatch in 2014, but the thermal camera shows 3 inches over your exterior walls and your July bill keeps climbing. We don’t just dump more on top. We locate the thin spots, air-seal the penetrations, install baffles where needed, then top to uniform depth. Most top-ups in New Braunfels run $1,800-$2,900 and include the before-and-after blower-door test.

Attic Insulation Replacement
When insulation is compressed, water-stained, or rodent-compromised, we remove it completely, sanitize the deck, seal every penetration, and reinstall. Replacement is more common in the 1970s-1990s stock near downtown New Braunfels than in newer builds, though we’ve done full pulls in growth-era homes after roof leaks or squirrel damage. Most replacements run $3,500-$5,500.

Attic Baffles & Ventilation Prep
New Braunfels’s humidity - especially near the Guadalupe and Comal River corridors - kills insulation that can’t breathe. We install proper baffles at every eave to maintain soffit-to-ridge airflow, preventing the moisture buildup that turns fiberglass into a mold substrate. Baffles are standard on every top-up and replacement we do; we don’t consider an attic finished without them.

AfterTrusted Brands We Service in New Braunfels
We stock Owens Corning, Johns Manville, and GreenFiber materials on our New Braunfels trucks, with Demilec spray foam available for specialized applications like sealed attics or knee-wall assemblies in historic Gruene renovations. No proprietary lock-in - we specify what performs for your roof pitch, your ventilation, and your budget. Because we carry stock locally, most New Braunfels jobs start within a week of your written approval, not after a two-week material order.
Common Attic Insulation Problems We See in New Braunfels Homes

- Patchy blown fiberglass in growth-era subdivisions. In Veramendi, Hunter’s Crossing, and Elm Creek, we regularly find R-30 depth at the hatch dropping to 3-5 inches over exterior walls and recessed can lights. The thermal camera doesn’t lie, and neither do the summer electric bills.
- Freeze-vulnerable plumbing penetrations. New Braunfels sits on the Balcones Escarpment, where Winter Storm Uri proved that attics insulated for summer-only performance leave supply lines exposed. We insulate and air-seal around every plumbing penetration as standard.
- Moisture-compromised assemblies near river corridors. Homes near the Guadalupe and Comal Rivers experience higher ambient humidity. Without proper baffles and vapor management, that moisture condenses against the roof deck and degrades fiberglass from the top down.
- Missing or collapsed baffles in newer builds. Fast crews in the 2015-2020 building boom often skipped baffles entirely or installed them backwards. We find blocked soffit vents in maybe one of three New Braunfels attics we open.

What moves you within these ranges: attic square footage, current insulation condition, accessibility (scuttle vs. pull-down stairs), and whether we find active air leaks that need sealing first. We never blow insulation over an unsealed attic floor - that’s not an upsell, it’s a prerequisite. Every price is written, every scope is written, and every job carries the 365-Day Done Right Promise. Call (830) 243-6352 for your specific number - estimates are free, and we bring a thermal camera.

FAQs - Attic Insulation in New Braunfels

Because the crew that blew your attic was racing the construction schedule during New Braunfels’s fastest growth phase, and they likely achieved full depth only at the hatch. Our thermal scans in 2014-era Veramendi and Hunter’s Crossing homes routinely show 4-6 inches over exterior walls while the hatch area reads a healthy 12 inches. You’re paying to condition air that’s escaping through thin spots you can’t see from below. Call (830) 243-6352 and we’ll show you on the thermal camera - estimate is free.
Yes. The Balcones Escarpment funnels Arctic air directly into Comal County in ways that flatland markets don’t experience. We air-seal and insulate around every plumbing penetration, vent stack, and chimney chase as standard - not as an add-on. Homes that survived Uri without frozen pipes typically had this detail right; homes that didn’t, didn’t. We document every penetration we seal with a photo in your record.
A proper top-up to uniform R-38 with sealed air leaks will reduce your cooling load measurably - we verify this with before-and-after blower-door numbers on every job. Radiant barrier helps specifically on roof decks with direct afternoon sun exposure, which is common in the newer subdivisions with minimal tree canopy along FM 306. We don’t sell radiant barrier where it won’t perform; we measure attic temperature and roof orientation first.
It changes how we install, not necessarily what material we use. River-corridor homes in New Braunfels need active ventilation management - proper baffles, intact soffit vents, and no blocked ridge exhaust - or any insulation will eventually hold moisture. We assess your existing ventilation before specifying material. Cellulose with proper vapor management often outperforms fiberglass in these specific microclimates.
We install Owens Corning, Johns Manville, and GreenFiber as our standard offerings, with Demilec spray foam for sealed attic or specialty applications. We don’t carry proprietary house brands with locked-in pricing. The brand we specify depends on your attic’s ventilation, your roof pitch, and whether we’re matching existing material. You’ll see exactly what we’re installing in your written scope before work starts.
