How Knauf Products Fail - and How We Fix Them

• Knauf EcoSeal cavity gaps in older New Braunfels slab homes. EcoSeal, a water-based elastomeric sealant sometimes paired with Knauf batt installations, can shrink and pull away from top plates in homes built between 1985 and 2005, especially where the Guadalupe Valley’s clay soil has shifted framing over decades. We remove the compromised sealant with mechanical abrasion, reseal with compatible acrylic-latex or upgrade to closed-cell foam at the homeowner’s direction, then verify with a blower-door test.
• Knauf Jet Stream Ultra settling in 2×4 exterior walls. This blown-in fiberglass was marketed for dense-pack wall applications but can settle 15-20% below the intended density in walls with irregular stud spacing common in Canyon Lake-area construction. We core-test the cavity density with a boroscope, then redensify with new Jet Stream Ultra or switch to a higher-density alternative like Knauf’s InsulSafe SP if the wall configuration allows.
• Knauf Momentum moisture retention in south-facing walls. Momentum, a higher-R-value batt line, uses a binder that can hold localized moisture when installed against unventilated brick veneer without a proper drainage gap, a condition we see frequently in New Braunfels homes with 1970s-era additions. We pull the affected batts, install a proper air gap or rainscreen detail, and replace with moisture-tolerant mineral wool or properly detailed fiberglass.
• Knauf Insulation Board EPS thermal bridging at rim joists. The EPS board line, sometimes used in basement and crawl space perimeter walls in Comal County’s hill-country homes, leaves gaps at framing intersections that create measurable thermal bridges. We supplement with cut-and-cobble spray foam or rigid polyiso at these junctions, then document the improvement with infrared imaging and blower-door comparison.
• Knauf Acoustical Board degradation in interior partition walls. Used for sound control between bedrooms and media rooms, this product can sag or compress where it was friction-fit without proper supports in walls with 24-inch stud spacing. We reinstall with proper mechanical fastening or upgrade to a denser, supported acoustical system depending on the STC rating the homeowner needs.

Our Knauf Wall Insulation Process

1. 1
   Call and scheduling. A live person answers, or you can text. We book a diagnostic visit with a named technician and send a text when they’re en route.
2. 2
   On-site assessment and blower-door baseline. We run a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope is losing. For Knauf wall jobs, we also borescope at least two wall cavities to verify existing product condition and density.
3. 3
   Written price and scope. Before any work starts, you receive a flat price, written scope, and written warranty. Haven Standard Clause 1: no exceptions.
4. 4
   Air sealing first, then insulation. We seal top plates, electrical penetrations, and any bypasses before adding or replacing wall insulation. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
5. 5
   Installation with OEM or quality aftermarket materials. We source Knauf products directly when they’re the right fit for the application, or specify alternatives from Owens Corning, Johns Manville, Rockwool, or other named manufacturers when performance or availability dictates. No proprietary lock-in.
6. 6
   Post-job documentation. You receive a Documented Photo Record, the final blower-door reading, and a printed comparison to the baseline. We file a copy by address in case you sell or need warranty service later.

What Knauf Wall Insulation Costs in New Braunfels

Most Knauf wall insulation jobs in New Braunfels fall into these ranges:

• Drill-and-fill empty 2×4 walls with Knauf Jet Stream Ultra: $2,800-$4,200 for a 1,600-square-foot home
• Remove and replace degraded Knauf batts in exterior walls: $3,600-$5,800 including air sealing of penetrations
• Interior wall soundproofing with Knauf Acoustical Board: $1,800-$3,200 per wall, depending on height and electrical complexity
• Rim joist and basement perimeter with Knauf EPS plus spray foam hybrid: $2,400-$4,600

What moves the price: accessibility of wall cavities, presence of existing insulation requiring removal, need for electrical or plumbing relocation, and whether we find unsealed air bypasses that must be addressed before insulation goes in. We do not blow insulation over unsealed attic floors or wall top plates. Call (830) 243-6352 for a written estimate - the price we give is the price you pay.
