Owens Corning Attic Cleaning & Rodent Proofing in Irvine: What to Know First
We clean and rodent-proof attics in Irvine that contain Owens Corning insulation, and most jobs are completed in a single visit. Typical pricing runs $1,400 to $3,800 depending on attic size, contamination level, and whether we’re removing or keeping your existing Owens Corning material. If rats or mice have nested in your Owens Corning fiberglass, we remove the soiled material, sanitize the decking, seal every entry point, and install fresh insulation that works the way Owens Corning intended.
This page is for Irvine homeowners whose Owens Corning attic has been compromised by rodents, dust, or years of neglect. Call (949) 832-7835 and a live person answers, 24/7, no voicemail runaround.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning ProPink blown-in fiberglass loses its loft after rodent traffic. Rats and mice compact the material as they tunnel, crushing the air pockets that give it R-value. In Woodbridge homes from the 1980s and 1990s, we regularly find ProPink that’s been flattened to half its original depth. We remove the compacted material, sanitize the decking, and blow in fresh Owen’s Corning AttiCat Pink blown-in at the correct depth for Irvine’s climate zone.
- Owens Corning R-30 and R-38 batt insulation wicks rodent urine and holds it for years. The fiberglass itself doesn’t absorb liquid, but the kraft paper facing does. Once rats nest in faced batts, the urine smell soaks into the paper and won’t come out with air spray or enzyme mist alone. Our fix is full removal of the faced material, deck decontamination with an antimicrobial, and reinstallation with unfaced batts or blown-in where appropriate.
- Owens Corning FOAMULAR rigid board at soffit vents gets chewed into confetti. Rodents love gnawing FOAMULAR XPS panels, particularly at the eaves where they meet vent openings. We find it shredded and scattered, which tells us exactly where the animals are entering. We replace the damaged board with new FOAMULAR, then install galvanized exclusion mesh at the vent openings so the repair holds.
- Owens Corning Thermafiber mineral wool collects dust that masks moisture problems. In Irvine attics with older Thermafiber batts, the dense fibers trap years of dust, pollen, and construction debris. That’s not just dirty, it hides the signs of roof leaks and condensation until the decking below is already damaged. During a cleanout, we inspect the exposed decking for water staining and tell you what we find, before new insulation covers it again.
- Owens Corning AttiCat blown-in fiberglass acts as a rat highway when it’s overfilled above the top plate. If a previous contractor piled material too high along the attic perimeter, rodents move invisibly through it. During rodent proofing, we correct the depth so you can actually see activity at the wall line, then we seal the top-plate gaps that let air and pests through from the living space below.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
Here’s how a typical Owens Corning attic restoration runs from first call to sign-off.
- 1
Phone diagnostic. You call, we answer live. We ask about attic access, insulation type, signs of rodents, and how long the problem’s been going on. That gives us a rough scope before we ever set foot in your home.
- 2
Attic inspection and quote. A background-checked, uniformed technician inspects the space, identifies the Owens Corning material involved, maps entry points, and gives upfront pricing. No surprises, no pressure.
- 3
Contaminated material removal. We use commercial HEPA-filtered vacuums to pull out soiled Owens Corning insulation, droppings, nesting debris, and blown-in material that’s been compacted beyond usefulness.
- 4
Sanitizing and decontamination. We treat the decking, joists, and remaining surfaces with an EPA-registered antimicrobial that breaks down rodent allergens and odor.
- 5
Rodent exclusion. We seal entry points with corrosion-resistant mesh, foam, and metal flashing where needed. This is the step that keeps the problem from coming back.
- 6
Fresh insulation and final check. We install new Owens Corning insulation at the correct R-value for Irvine, air seal the top plates, and walk you through what we did. Every job is covered by our 90-Day Done Right Promise.

FAQs
Your Owens Corning insulation warranty covers manufacturing defects, not rodent damage, water contamination, or improper installation. Professional attic cleaning and rodent exclusion does not void your warranty. In many cases, our work restores conditions that make the product perform the way the warranty intended it to.
If the contamination is light and the material still has loft, surface-cleaning and deodorizing can work. But if rats have tunneled through Owens Corning blown-in fiberglass or nested in faced batts, the material is compromised and replacement is the only way to get your R-value and air quality back. We’ll show you what we find before we recommend anything. Call (949) 832-7835 and we’ll walk you through it.
Most Irvine attic cleanouts and rodent proofing jobs are completed in a single visit, usually 4 to 8 hours depending on attic size and access. Large jobs with heavy contamination may require a second day. We’ll tell you upfront what to expect before we start.
We service Irvine daily and can usually schedule within 24 to 72 hours. If rodents are actively chewing Owens Corning material or you’ve discovered wiring damage, tell us when you call and we’ll prioritize you. A live person answers around the clock at (949) 832-7835.
In Irvine, a full cleanout with new Owens Corning blown-in insulation typically costs $2,200 to $3,800, while leaving compromised material in place just postpones the problem and can lead to higher energy bills and more rodent activity. Clean it once, seal it permanently, and you stop paying for the same fix twice. Call (949) 832-7835 for an exact quote, free of charge.
