Owens Corning Attic Cleaning & Rodent Proofing in Fullerton: What to Know First
Owens Corning attic cleaning and rodent proofing in Fullerton typically runs $1,200 to $3,800 depending on attic size, contamination level, and whether your insulation needs full replacement. Most Fullerton jobs are completed in one to two days, and we’re an independent Owens Corning service provider, not a franchise or authorized dealer, so we answer to you, not a corporate office. If you’ve got rodent activity in an Owens Corning-insulated attic, call (657) 216-9948 and we’ll give you a straight answer on what you’re dealing with.
This page is for Fullerton homeowners who have Owens Corning insulation in their attic and have discovered evidence of rodents, or who suspect their attic needs cleaning after years of accumulated dust, droppings, or old damaged insulation. Walt Brenner founded Walt’s Insulation in 2000, and we’ve spent the last 25 years working in Fullerton attics from the older ranch-style homes near the Fullerton Arboretum to newer construction across town. You’ll get a live person on the phone, a real assessment, and honest pricing.
How Owens Corning Products Fail and How We Fix Them
Owens Corning makes solid insulation products, but no insulation is rodent-proof on its own. Here’s what we actually find in Fullerton attics when Owens Corning materials have been compromised:
- ProPink blown-in fiberglass becomes a nesting paradise. Loose-fill Owens Corning ProPink (also sold as AttiCat) is exactly what rats and mice want: soft, warm, and easy to tunnel through. Once rodents nest in blown-in fiberglass, the material compresses, loses its R-value, and gets saturated with urine and droppings. We remove the contaminated fill entirely, sanitize the attic deck, and install fresh material only after exclusion is complete. You can’t clean what’s been used as a toilet.
- R-30 and R-38 kraft-faced batts get shredded for nesting. Owens Corning fiberglass batts with kraft paper facing are common in older Fullerton homes built in the 1960s and 70s. Rodents tear the paper facing off for nesting material, and the exposed fiberglass loses its structure. We see this constantly in the neighborhoods around Chapman Avenue and north Fullerton. The fix is removing the damaged batts, sealing entry points, and reinstalling new material.
- AttiCat blown-in systems hide rodent entry points. The AttiCat blown-in system installs fast and evenly, but deep loose fill buries the top plates and soffit gaps where rodents actually get in. You can’t see the entry point under 18 inches of insulation. Our techs pull back the fill along the eaves, inspect every top plate and wire penetration, and seal before replacing anything.
- Radiant barrier and foam board get chewed through. Owens Corning Foamular rigid foam board and radiant barrier products don’t stop determined rodents. Rats chew through foam board like it’s balsa wood. We find long gnawed channels along gable ends and under eaves where foam board was used as blocking. The repair is replacing the chewed sections and installing galvanized hardware cloth or steel wool in the gaps before reinstalling insulation.
- Dirty fiberglass reads as “insulation failure” when it’s actually an air-sealing problem. Fullerton’s summer heat and cool winters create stack effect: hot air rises into the attic and pulls dust and particulates through can lights, vent penetrations, and drywall gaps. Owens Corning fiberglass (both batt and blown) acts as a filter and turns dark gray over time. The insulation isn’t defective; it’s doing exactly what a filter does. The fix is air sealing the attic floor before cleaning or replacing the material, or you’ll have the same dirty insulation again in five years.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
Every job starts the same way: someone actually looks at the attic before we quote anything. Here’s how a typical Owens Corning attic cleaning and rodent proofing job runs for us:
- 1
Call and talk to a person. You call (657) 216-9948, tell us what you’re seeing or hearing. We schedule a visit. No answering service, no email ticket.
- 2
In-attic inspection. One of our background-checked, uniformed techs gets into the attic with a flashlight and a camera. We document everything: droppings, gnawed Owens Corning batts, compressed ProPink fill, entry points, air leaks, and any damaged ductwork.
- 3
Plain-English plan and upfront price. We tell you exactly what we found, what it’ll cost to fix, and what happens if you do nothing. No scare tactics. You get a written estimate before any work starts.
- 4
Removal and sanitizing. We remove contaminated insulation, vacuum the attic deck, and sanitize the surfaces. Depending on the level of contamination, this can take a full day or more. It’s miserable work, and we do it right.
- 5
Rodent exclusion and entry sealing. We seal every entry point we found: soffit gaps, roof intersections, wire penetrations, gable vents. Galvanized hardware cloth, steel wool, and foam sealant go in where appropriate. This is the step that stops the problem permanently.
- 6
Fresh insulation installation and final walkthrough. We reinstall Owens Corning material (or another brand if you’d prefer), check our work, and show you photos of everything. The Done Right Promise covers the work for life. If it’s not done right, we make it right, no runaround.

FAQs
In most Fullerton attics, yes. Rodent urine and droppings contaminate fiberglass insulation, and the material compresses from nesting activity, losing its R-value. Blown-in Owens Corning ProPink can’t be effectively sanitized once soaked with urine. We recommend removal and replacement in nearly every rodent contamination case. Call (657) 216-9948 for an assessment and exact quote.
Sometimes, if the contamination is light and caught early. Clean debris, minor dust, and a few droppings can often be handled with targeted removal and vacuuming. But if rodents have been nesting in blown-in fiberglass or kraft-faced batts, the honest answer is replacement. We’ll tell you which one you’re dealing with and show you photos so you can decide without guesswork.
We run same-week scheduling for most Fullerton jobs, and for active rodent infestations we try to get out within 48 hours. The phone is answered 24/7, so you’ll talk to a real person whether it’s 2 PM or 2 AM. We’ll schedule an inspection and give you a written estimate on the spot.
For minor damage in a small area, targeted repair is cheaper, usually $200 to $600. For contamination, heavy saturation, or severe compression from nesting, replacement is the better long-term investment because repaired fiberglass never performs like new. We’ll give you both numbers and let you decide. Estimates are free, and there’s no trip charge in our county.
We’re an independent Owens Corning service provider, not an authorized dealer, so we can’t process manufacturer warranty claims directly. What we can do is install new Owens Corning material according to spec, document everything, and stand behind our labor with the Done Right Promise for life. The materials themselves carry Owens Corning’s own product warranties, which we’ll help you understand. Call (657) 216-9948 with your specific situation.
