How Knauf Products Fail - and How We Fix Them

• Knauf Jet Stream UltraSettled density loss in hot San Marcos attics. This blown-in fiberglass settles faster than spec in our climate, where attic temperatures regularly hit 140°F from May through September. The material compresses under its own weight plus rodent traffic, creating thin spots that rodents tunnel through. We remove the compromised Ultra, seal every penetration with fire-rated caulk and steel wool, then reinstall to manufacturer density with a documented depth check every 25 square feet.
• Knauf Ecose Technology batts shredded for nesting material. The brown, formaldehyde-free binder that makes Ecose distinctive also makes it attractive to roof rats - they tear the batts into strips for nest building, especially near soffit vents in neighborhoods like Willow Creek and Blanco River Village. We extract the shredded material, fog with botanical disinfectant, and install rigid rodent barriers at vent entry points rather than relying on spray foam that rats chew through.
• Knauf Insulation Board (XPS) chewed at HVAC penetrations. The rigid pink board installed around attic-mounted air handlers and duct boots gets gnawed for access to conditioned air lines. Rats leave a distinctive crushed-glass texture at the edge. We cut back damaged board, install 26-gauge galvanized flashing collars, then replace with fresh board - never patching over rodent highways.
• Knafs blow-in blanket system (BIBS) compromised by urine saturation. The mesh fabric holding blown fiberglass in wall and knee-wall cavities wicks rodent urine downward, creating a chronic ammonia source that standard deodorizers won’t touch. We cut the mesh, remove the saturated pack, treat the sheathing with enzyme digesters, then reinstall with new mesh - documenting the moisture meter readings before we close up.
• Knauf loose-fill contaminated by prior contractor’s shortcut sealing. We regularly find Knauf attics in San Marcos where a previous contractor blew insulation directly over unsealed top plates and recessed can lights - the Haven Standard violation we see most often. The air leakage creates thermal bypasses that rodents follow like roadmaps. We remove the Knauf, seal with fire-stop caulk and rigid baffles, then reinstall. The R-value tells you how slow heat moves through the material - the blower-door number tells you whether any of that matters.

Our Knauf Attic Cleaning & Rodent Proofing Process

1. 1
   Written price before arrival. We send a flat price based on attic square footage, access type, and contamination level - no “we’ll see when we get there.” Haven Standard Clause 1: written scope, written warranty, written price before anyone lifts a tool.
2. 2
   Blower-door baseline and photo documentation. We pressurize the house to measure air leakage at the attic plane, then photograph every Knauf product line present, damage pattern, and rodent entry evidence. You get this record before we start.
3. 3
   Controlled removal and HEPA containment. We extract contaminated Knauf material using negative-air machines, bagging by contamination type - general debris, urine-soaked, or rodent-carried - since disposal requirements differ.
4. 4
   Sanitizing and structural repair. We fog with botanical disinfectant (no bleach, which degrades wood fibers), replace chewed wiring jackets where found, and install exclusion hardware: 1/4-inch mesh at vents, copper wool at pipe penetrations, metal kick plates at fascia gaps.
5. 5
   Reinstall or upgrade, then verify. We reinstall Knauf to spec or upgrade to a different material if your goals have changed - we carry Owens Corning, Johns Manville, Rockwool, and others, so there’s no product lock-in. Final blower-door test and photo record delivered before we leave.
6. 6
   365-Day Done Right Promise activation. Written warranty, documented readings, and our direct line. If rodents breach our exclusion in year one, we return and fix it.

Why San Marcos Homeowners Call Topside Attic Insulation San Marcos for Knauf Work

We’ve cleaned and restored Knauf-insulated attics in San Marcos since 2016, from the 1970s ranch-style homes near Texas State where Ecose batts were retrofitted in the 2000s, to newer builds in the Trace that used Jet Stream Ultra from day one. Wes Okafor runs a blower-door test before and after every job, then hands you a single printed page with the before-and-after air-changes-per-hour figure. Our technicians are background-checked and uniformed; calls are answered by a live person, 24/7. We also service Reflectix and other brands, so if your attic has mixed materials from multiple installs, we don’t need to subcontract.
