How Knauf Products Fail - and How We Fix Them

• Knauf EcoSeal System gaps at top plates - The water-based acrylic sealant in Knauf’s EcoSeal line cures to a flexible membrane, but in Pflugerville’s 100°F+ attic summers it can pull away from OSB sheathing at the top plate junction if the substrate wasn’t primed to Knauf’s spec. We find this in homes built 2018-2022 in the Stone Hill Town Center corridor. Our fix: remove the failed bead, mechanically clean the wood with a wire brush and denatured alcohol, then reseal with Tremco Acoustical Sealant or equivalent - a butyl-based product that stays tacky at 140°F attic temps and bonds to dusty lumber.
• Knauf Jet Stream Ultra settling in kneewalls - This high-velocity blown fiberglass is designed to achieve R-49 at 14 inches, but in Pflugerville’s low-slope ranch attics with kneewall transitions, we regularly see it settle to 9-10 inches within 18 months, leaving the kneewall cavity underfilled and creating a thermal bypass that rodents exploit for nesting. We fix by removing the settled material, installing Knauf Insulation Board or equivalent rigid baffles at the kneewall top plate to maintain depth, then redensifying with a fresh blow at 1.2 pounds per cubic foot minimum.
• Knauf Momentum liner degradation from rodent urine - The kraft-faced vapor retarder on Momentum batts dissolves when saturated with rodent urine, which is common in Pflugerville homes near the Gilleland Creek watershed where roof rat pressure is highest. Once the facing fails, the fiberglass beneath compresses and loses R-value. We remove all contaminated batts by the square foot (documented in photos), treat the deck with an enzyme-based sanitizer, then reinstall unfaced Knauf EcoBatt or switch to Rockwool Comfortbatt if the homeowner wants rodent-resistant mineral wool.
• Knauf Attic Access System gasket compression - The EPDM gasket on Knauf’s pre-fab attic access stair units compresses permanently after about 5-7 years in Texas heat, creating a 1/4-inch gap that mice traverse easily. We see this constantly in Pflugerville’s 2015-2019 builds. Our fix: replace the OEM gasket with a silicone bulb seal rated for 200°F continuous exposure, then add a secondary weatherstrip and a latch adjustment so the hatch seats with 15 pounds of pressure - the blower-door test will show the difference.
• Knauf Insulation Shield gaps around B-vents - The galvanized shield that Knauf supplies for clearance around Type B gas vents is often installed with a 2-inch gap “to be safe,” but that gap becomes a superhighway for roof rats in Pflugerville’s mature neighborhoods like Windermere and Heatherwilde. We remove the shield, verify the 1-inch minimum clearance per IRC R806.2, then bridge the gap with 26-gauge sheet metal sealed with 3M Fire Block Foam - rodent-proof, code-compliant, and blower-door visible.

Our Knauf Attic Cleaning & Rodent Proofing Process

1. 1
   Inspection with photo documentation. We photograph every Knauf product line present, note the install date if visible on the batt stamp or blow-in bag remnants, and map rodent evidence - droppings, gnaw marks, urine fluorescence under UV - before touching anything.
2. 2
   Blower-door baseline. We run a pressurization test to establish CFM50 before any disturbance. In Pflugerville’s 2,000-square-foot 2017 builds, we typically see 3,800-4,500 CFM50 when Knauf EcoSeal has failed at the top plates.
3. 3
   Written scope and price. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
4. 4
   Removal, sanitizing, and rodent exclusion. We HEPA-vacuum all contaminated Knauf material, treat the deck with Vital Oxide or equivalent enzyme sanitizer, then seal every penetration larger than 1/4 inch with copper mesh and polyurethane - rodents cannot gnaw through copper.
5. 5
   Reinstall or upgrade. We reinstall with matching Knauf products where appropriate, or specify alternatives (Reflectix radiant barrier in sun-baked Pflugerville attics, Rockwool where fire resistance matters) with written justification.
6. 6
   Blower-door verification and photo record. We rerun the pressurization test and deliver before-and-after CFM50 numbers, plus a documented photo record of every step, before we leave.

What Knauf Attic Cleaning & Rodent Proofing Costs in Pflugerville

Most Knauf attic cleanouts and rodent proofing jobs in a Pflugerville home this size run between $2,400 and $4,800. A light cleaning with spot sealing and no insulation replacement sits at the low end. Full removal of contaminated Jet Stream Ultra or Momentum batts, deck sanitizing, copper exclusion work, and reinstall with fresh material pushes toward the high end. What moves the price: square footage, depth of existing Knauf insulation, extent of rodent contamination (guano saturation requires full removal per CDC guidance), and whether the EcoSeal system needs rework. We also service Reflectix radiant barrier systems where those are present. Call (737) 259-8352 for a written price - estimates are free, and we deliver the number before any work starts.
