Knauf Blown-In Insulation in New Braunfels: What to Know First
We provide independent Knauf blown-in insulation service in New Braunfels, typically completing attic jobs in one day with a written price delivered before any work starts. Most Knauf blown-in fiberglass or cellulose top-ups in our market run between $1.40 and $2.10 per square foot installed, depending on existing depth and access conditions. This page is for homeowners who already have Knauf insulation in their attic or walls and need it assessed, topped up, replaced, or supplemented after settling, moisture damage, or rodent activity. If you’re reading this because your energy bills climbed after a New Braunfels summer or your upstairs rooms won’t hold temperature, we can tell you exactly what your Knauf product is doing and what it isn’t. Call (830) 243-6352 for a free estimate with a written scope.
How Knauf Products Fail - and How We Fix Them
- Knauf Jet Stream Ultra fiberglass settles below labeled R-value in high-humidity attics. The product is designed to loft to R-38 at 12 inches, but we’ve measured settled depths of 8-9 inches in New Braunfels homes where attic ventilation pulls Gulf moisture through ridge vents year-round. The fix isn’t more fiberglass; it’s sealing the air bypasses first, then blowing to compensate for the compression we know will occur. We document pre- and post-depth with a ruler in the photo record.
- Knauf Ecobatt with ECOSE binder degrades around recessed can lights that weren’t properly sealed. The plant-based binder absorbs heat and off-gases slightly when exposed to sustained 140°F+ temperatures near unsealed IC-rated housings. We find this in River Road corridor homes from the 1980s where original cans were never boxed. Our fix: install fire-rated enclosures, seal with mastic, then replace the degraded batts with fresh blown-in fiberglass that won’t sit against hot surfaces.
- Knauf Insulation Blow-In Wool (mineral wool) bridges across joist bays instead of filling them. Mineral wool’s higher density means it doesn’t flow like fiberglass; inexperienced crews leave voids at bay perimeters and over top plates. We use a slower feed rate and cross-hatch pattern, then probe with a yardstick every third bay. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- Knauf cellulose products clump after roof leaks in New Braunfels’ spring storm season. April and May deluges find lifted shingles or failed flashing; cellulose wicks water horizontally across attic floors before homeowners notice ceiling stains. We remove the affected material, treat for mold if the moisture meter reads above 20%, and switch to blown-in fiberglass in the replacement if the roof geometry makes future leaks likely.
- Knafd dense-pack wall installations sag in balloon-framed walls common to pre-1970s New Braunfels construction. Without a bottom plate to contain the fill, gravity and vibration from nearby I-35 traffic gradually pull material down over 3-5 years. We fix this by installing fabric mesh retention at stud bays and using a higher-density pack with adhesive-enhanced cellulose, then verifying with thermal imaging from the interior.
Our Knauf Blown-In Insulation Process
- 1
Call and scheduling. A live person answers, or you text (830) 243-6352. We book a 2-hour arrival window; you get a text when the technician is en route.
- 2
Attic inspection and blower-door test. We run a pressurization diagnostic - a blower-door test that measures CFM50, or cubic feet of air leakage per minute at 50 pascals of pressure - before touching anything. In New Braunfels slab homes near the Guadalupe, we regularly see starting numbers above 3,500 CFM50. You get the printed reading.
- 3
Written scope and price. We identify your Knauf product by bag remnants, binder color, or fiber diameter under magnification. The scope specifies: air sealing locations, insulation type and depth, any removal required, and final blower-door target. Price is flat; no work starts without your signature.
- 4
Air sealing first, then insulation. Top plates, wire penetrations, chimney chases, and can lights get sealed with fire-rated foam or mastic. Only then do we blow. This is non-negotiable; we’ve seen too many Knauf jobs buried over leaky attics that performed like they had half the R-value on paper.
- 5
Installation and documentation. We blow to depth, probe for voids, and run the blower-door test again. You receive: before-and-after CFM50 readings, depth measurements at six attic locations, dated photos of sealed bypasses, and a written warranty. The 365-Day Done Right Promise applies from this date.
- 6
Cleanup and follow-up. We vacuum the access path and leave the photo record via email before the truck leaves your driveway. No callback windows measured in business days.

AfterWhat Knauf Blown-In Insulation Costs in New Braunfels
These are real ranges from jobs we’ve completed in Comal and Guadalupe counties, not teaser rates:

Prices include materials, labor, the blower-door test, and the Documented Photo Record. We also source from Owens Corning, Johns Manville, Rockwool, and other manufacturers - no proprietary lock-in means we specify what’s right for your assembly, not what moves a particular inventory. Bring us any written estimate; we’ll read it with you. Call (830) 243-6352 for your exact written price.
Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Knauf Work
We’ve sealed and insulated over 9,000 homes since 2016, and the Knauf jobs stick in memory because the products behave differently than fiberglass from other mills - different settling curves, different moisture response, different handling characteristics on the blower. Wes Okafor and our crew know these differences because we’ve logged the blower-door numbers on hundreds of Knauf installations across New Braunfels, from the older slab homes off River Road to newer builds in Veramendi where code-minimum insulation barely handles our summer heat gain.
We’re an independent Knauf service provider - not affiliated with or authorized by Knauf - which means we work across brands without pressure to push one product line. We also service Reflectix and other radiant barrier systems when your attic assembly needs a hybrid approach. Every job gets the Haven Standard: written price before work starts, named technician, text-on-the-way, and printed documentation when we leave. Calls are answered by a live person, 24/7.
FAQs
No. Knauf’s product warranty covers manufacturing defects in the material itself, not the installation, and does not require authorized dealer status to remain valid. What voids coverage is improper installation - such as installing over unsealed air leaks or compressing the product below labeled depth - which is why we document every step. If you have a material defect claim, we provide the installation records Knauf will request. Call (830) 243-6352 if you’re unsure what warranty paperwork you have.
Most Knauf blown-in attic jobs are scheduled within 3-5 business days; emergency removals for water damage or rodent contamination can often be booked next-day. Spring 2024, we had a River Road homeowner with saturated Knauf cellulose after a hail-compromised ridge vent - crew was on-site in 36 hours, removal completed same day, and new fiberglass blown after the roofer patched. Call (830) 243-6352 for current availability.
Top-ups are cheaper short-term but often wasteful long-term. If your Knauf fiberglass has settled unevenly due to air movement through the attic, blowing more material over the top locks in the bypass problem and you’ll settle again in 3-5 years. We recommend removal and re-installation with proper air sealing when the existing depth is below 50% of original or when thermal imaging shows more than 15°F surface temperature variation across the attic floor. The written scope breaks both options with honest payback math. Call for a free estimate.
We can match Knauf’s thermal performance (R-value per inch) and often source the identical product line, but color and slight texture differences between production lots are normal and don’t affect function. For additions or partial repairs, we document what was existing and what was added so future owners or inspectors have the full picture. If exact visual match matters for resale, we note that in the scope and source accordingly. Call (830) 243-6352 to discuss your specific attic layout.
You receive four items: a written invoice with flat price and scope, before-and-after blower-door test results on printed forms, dated photos of key work stages including depth measurements, and a written 365-Day Done Right Promise warranty. Wes keeps a copy of every blower-door report filed by address, which has helped past New Braunfels clients when buyer’s inspectors asked questions during resale. No documentation is “available on request” - it’s delivered before we leave.
