Call (657) 213-3642

This page is for homeowners who’ve spotted rodent droppings near their Owens Corning insulation, heard scratching in the ceiling, or noticed insulation performance dropping because pests have compacted and soiled it. If that’s you, call (657) 213-3642 and Neil Ashford or one of our techs will walk you through what’s happening up there.

Key Takeaways:

• Rodents treat Owens Corning fiberglass batts and blown-in insulation as nesting material, and Garden Grove’s rat population makes attic intrusion common year-round.
• We remove contaminated insulation, sanitize the attic deck, seal entry points, and install fresh material if needed.
• Every attic cleaning and rodent proofing job is covered by our 90-Day Done Right Promise.
• Most jobs are done in one visit. A live person answers 24/7 at (657) 213-3642.

How Owens Corning Products Fail - and How We Fix Them

Owens Corning makes solid insulation. But in Garden Grove attics, rodents and moisture create failure patterns we see over and over. Here’s what actually happens to Owens Corning material up there and what we do about it.

• Owens Corning EcoTouch Pink Fiberglas batts become rodent highways. Rats tunnel through the soft fiberglass, flattening it into dense, soiled mats that lose R-value fast. We see this all over Garden Grove, especially along the Euclid corridor where older ranch homes have easy roof-to-attic access points. The fix: remove contaminated batts, sanitize, seal entry points, and install fresh insulation if you’re keeping the same R-value.
• Owens Corning AttiCat blown-in system gets compacted by nesting activity. AttiCat is a great blown-in product, but when rodents burrow through it, they compress huge sections. Compacted fiberglass loses most of its insulating power. In West Garden Grove homes, we regularly find AttiCat depths that should measure 14 inches sitting at 4 to 6 inches after a rat colony moves through. We vacuum out the contaminated material, sanitize, and re-blow to proper depth.
• Owens Corning ProPink blown-in insulation hides moisture damage until it’s severe. ProPink doesn’t show water staining the way batts do. By the time homeowners notice a ceiling discoloration or smell, the insulation has been holding moisture against the drywall for months. In Garden Grove’s coastal humidity cycles, that means mold risk. During a cleaning job, we check the attic deck and roof sheathing for moisture intrusion before installing anything new.
• Owens Corning Thermafiber mineral wool holds rodent odor far longer than fiberglass. Thermafiber is a fire-resistant mineral wool product we respect, but it traps urine and feces odors stubbornly. Spot cleaning doesn’t remove the smell. Full removal of the affected material and enzyme-based sanitization of the decking is the only fix that actually works. We’ve done enough of these to know that skipping the sanitizing step means the smell returns in a few weeks.
• Owens Corning vapor barriers and kraft-faced batts get chewed into nest liners. Rats shred kraft paper facing and thin vapor barrier film to line nests. Once the facing is gone, the batt loses its air-sealing properties and moisture gets through. We remove the shredded material during cleanout and recommend air sealing the attic floor before new insulation goes in.

Our Owens Corning Attic Cleaning & Rodent Proofing Process

Here’s how a typical Owens Corning attic restoration goes when you call Warmline Insulation Co. in Garden Grove. We’ve done hundreds of these, and the process is built to get your attic clean, sealed, and protected in one visit when possible.

1. 1
   Call and diagnosis. You call (657) 213-3642, a live person answers, and we ask about the symptoms: scratching sounds, droppings, smells, visible damage. We schedule a walkthrough, usually the same week.
2. 2
   Attic inspection. We get into the attic and document everything with photos: insulation type and depth, entry points, rodent activity, moisture damage, and what Owens Corning products are installed.
3. 3
   Removal and cleanout. We vacuum out contaminated Owens Corning insulation using commercial vacuums, bag it, and haul it away. No dumpster-in-your-driveway situation.
4. 4
   Sanitizing and decontamination. We treat the attic deck and framing with an enzyme-based sanitizer that breaks down rodent urine, feces, and odor. This step matters just as much as insulation removal.
5. 5
   Rodent proofing and exclusion. We seal entry points with rodent-proof materials: steel mesh over vents, hardware cloth around pipe penetrations, and foam sealant where appropriate. Every gap we find gets closed.
6. 6
   Fresh insulation and final check. We install new Owens Corning insulation (or another brand if you prefer) to the correct R-value for Garden Grove’s climate. Then we do a final visual inspection and walk you through what we did. Every job is backed by the 90-Day Done Right Promise: if it’s not right, we make it right.
