This page is for Pomona homeowners who already have Owens Corning insulation in their attic and are dealing with rodent activity, old droppings, nesting debris, or that stale attic smell that drifts down into the house. If you’re seeing droppings in the garage or hearing scratching above the ceiling at night, the sooner we get in there, the less damage to your insulation, ductwork, and wiring.

How Owens Corning Products Fail - and How We Fix Them

Owens Corning makes solid insulation, but no product is immune to what rats and mice do inside a Pomona attic. Here’s what we regularly find in this area, and what we do about it:

• Owens Corning ProPink blown-in fiberglass gets tunneled and compacted. Rodents burrow through loose-fill insulation to create nesting pockets near heat sources like recessed lighting cans and furnace flues. The insulation gets matted down, which kills its R-value. We remove the contaminated material, vacuum out the droppings and nesting debris, and install fresh blown-in insulation to the correct depth for Pomona’s climate zone. In the 110-degree summers we get here, proper attic insulation depth matters more than most people realize.
• Owens Corning R-30 and R-38 fiberglass batts hold urine odors long after the rodents are gone. Fiberglass batts and rolls are especially good at trapping the ammonia smell from rodent urine. You can’t shampoo it out. When we find batts with heavy staining or odor, we remove and replace them rather than trying to deodorize something that will keep off-gassing into the living space every time the attic heats up.
• Owens Corning AttiCat expanding blown-in system insulation settles unevenly after rodent damage. The AttiCat system is designed to maintain loft, but when rodents burrow through it, you get dips and bare patches that show up as hot rooms and high AC bills. We re-level and top off the insulation to restore consistent coverage, then seal every entry point so you’re not paying to re-insulate the same attic twice.
• Faced batt kraft paper becomes rat nesting material. We’ve opened dozens of Pomona attics where the kraft paper facing on Owens Corning batts has been shredded and dragged into nest piles. The exposed fiberglass underneath then holds moisture, which invites mold in our damp winter months. We remove the damaged batts, address the moisture source, and re-insulate with unfaced material where appropriate, with air sealing done at the ceiling plane.
• Owens Corning Thermafiber mineral wool gets moved aside, not destroyed. Rodents don’t usually chew mineral wool the way they chew fiberglass, but they will push it out of the way to create travel lanes along exterior walls. In attics where Thermafiber is present, we can often clean it, sanitize it, and put it back in place after rodent proofing, which saves the homeowner money on replacement material.

Our Owens Corning Attic Cleaning & Rodent Proofing Process

1. 1
   Access and inspection. We start with a full attic inspection, looking for rodent entry points, damaged Owens Corning insulation, compromised ductwork, and signs of electrical wire chewing. We document what we find with photos so you can see the problem for yourself.
2. 2
   Contaminated material removal. We remove droppings, nesting debris, soiled insulation, and any dead pests, bagging everything for safe disposal. We use HEPA-filtered vacuums to keep dust out of your living space.
3. 3
   Sanitizing and decontamination. We treat affected surfaces with an enzyme-based deodorizer and sanitizer that breaks down urine and feces residue, eliminating the odor source rather than masking it with fragrance.
4. 4
   Rodent proofing and exclusion. We seal entry points including gable vents, roof joints, plumbing penetrations, and soffit gaps using galvanized steel mesh, metal flashing, and pest-resistant sealant. Rodents in Pomona chew through foam and caulk, so we use materials they can’t gnaw through.
5. 5
   Insulation restoration. We re-level existing Owens Corning insulation or install fresh material to restore proper R-value and consistent attic coverage. You get the right depth for our climate, not just whatever was left up there.
6. 6
   The check and the promise. Before we leave, we walk the attic again to confirm every entry point is sealed and the insulation is performing. Then we put our 90-Day Done Right Promise in writing, so if anything isn’t right, we make it right.

What Owens Corning Attic Cleaning & Rodent Proofing Costs in Pomona

Pricing depends on attic size, how much contamination exists, and how many entry points need sealing. Here are the ranges we see most often in Pomona:

What moves the price most is how much insulation needs removal and replacement. If the contamination is localized, we clean and sanitize and you keep most of your existing insulation. If rats have been living up there for years, full removal and fresh blown-in is usually the right call. The $89 Seasonal Tune-Up is a good starting point if you’re not sure whether you need full work. Estimates are free, so you’ll know your number before you commit to anything.

We’ve been working in Pomona attics since 2011, including older homes near Ganesha Park where the insulation was original to the house and the rodent activity was older than some of the wiring. Neil Ashford built this company on the idea that homeowners deserve a straight answer, even when the answer is “you don’t need to spend money on that yet.” Our technicians are background-checked and uniformed, they show up on time, and they know Owens Corning material the way a mechanic knows a specific engine platform. We also service other brands including Reflectix, so if your attic has a mix of materials, we can handle it without calling in another contractor. Most jobs are complete in one visit, and our 90-Day Done Right Promise backs every attic cleaning and rodent proofing job we do in Pomona.
