How Owens Corning Products Fail - and How We Fix Them

• Owens Corning AttiCat PINK Blown-In Insulation settling in Yorba Linda’s heat cycles. The fiberglass loose-fill in the AttiCat system compacts when attic temperatures swing between 55°F winter nights and 140°F July afternoons, especially in hillside homes off Bastanchury Road where roof decks radiate downward. What reads as R-38 on the bag often performs like R-25 within five to seven years. We remove the settled material, air-seal the top plates and can-light penetrations, then reinstall to proper depth with a density check every 100 square feet.
• Owens Corning ProCat Loose Fill contaminated by roof-rat urine and nesting. The fine glass fibers in ProCat bind with organic matter, so rodent waste doesn’t just sit on top - it works into the matrix and creates a persistent ammonia source. Standard vacuuming leaves residue. We use HEPA-filtered removal, apply an enzymatic decontamination treatment specific to fiberglass substrates, then verify with ATP surface testing before any new material goes in.
• Owens Corning Foamular Rigid Board chewed at perimeter and penetration edges. The XPS foam in Foamular boards is dense enough that rats target the softer edges where the board meets framing or where plumbing vents penetrate. We find this regularly in Savi Ranch corridor homes with original 2005-2012 construction. Our fix: remove damaged sections, install galvanized steel flashing at all edges, then replace with fresh board or transition to a rodent-resistant assembly depending on the access pattern.
• Owens Corning Raft-R-Mate baffles collapsed or displaced by squirrel traffic. The polystyrene vent baffles crush under weight and create blocked soffit vents, which traps moisture and voids the attic’s designed ventilation path. In Yorba Linda’s dry climate, homeowners notice this first as a spike in summer cooling load, not as visible damage. We replace collapsed baffles with metal-reinforced equivalents and screen the soffit openings with 1/4-inch hardware cloth.
• Owens Corning EcoTouch batts degraded by rodent burrowing in kneewalls. The recycled-content binder in EcoTouch batts breaks down when saturated with oils from rodent fur, creating bare spots in kneewall cavities that read fine from the attic side but leak conditioned air into unconditioned space. We pull the affected batts, treat the framing, and reinstall with encapsulated batts or dense-pack cellulose depending on cavity geometry.

Our Owens Corning Attic Cleaning & Rodent Proofing Process

1. 1
   Site assessment and written price. We inspect the attic, identify the Owens Corning product lines present, document contamination extent with photos, and deliver a written scope and price before any work starts.
2. 2
   HEPA removal and decontamination. All compromised Owens Corning material comes out under negative air pressure. We treat exposed framing with an enzymatic cleaner rated for fiberglass-contact substrates.
3. 3
   Rodent proofing and exclusion. We seal entry points with steel mesh, concrete, or metal flashing - materials rats cannot chew through - and map the exclusion work on a diagram you keep.
4. 4
   Air sealing before reinsulation. Top plates, wire penetrations, can lights, and chimney chases get sealed. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - to establish a baseline.
5. 5
   Owens Corning or multi-brand reinstall. We reinstall with matching Owens Corning materials or, if the original line is discontinued or unsuited to the repaired assembly, specify a quality equivalent from Johns Manville, Knauf, or Rockwool with your approval.
6. 6
   Final test and documented record. A second blower-door test shows the improvement. You receive the photo record, the before-and-after numbers, and the written warranty. Seal the leaks first. Then insulate. The numbers will tell you whether it worked.

What Owens Corning Attic Cleaning & Rodent Proofing Costs in Yorba Linda

Price moves with attic square footage, depth of contamination, accessibility (truss vs. rafter, ductwork density), and whether the original Owens Corning line is still available or requires substitution. We also service Reflectix radiant barrier systems when those are present in the same attic. Every estimate is free, written, and delivered before any work starts. Call (909) 323-1675 to schedule.
