Owens Corning Attic Cleaning & Rodent Proofing in Costa Mesa: What to Know First
Owens Corning attic cleaning and rodent proofing in Costa Mesa typically runs $950 to $2,400 depending on attic size, contamination level, and how much exclusion work the roofline needs. Most jobs are completed in a single visit, and we work as an independent Owens Corning service provider, not a manufacturer-authorized shop, which means we can choose the right fix for your home without warranty games. If you’ve got rodents in your Owens Corning insulation or just years of accumulated dust and debris up there, call (657) 224-2897 and a live person answers 24/7, never a voicemail.
This page is for Costa Mesa homeowners who already own Owens Corning products in their attic and need cleaning, sanitizing, or rodent exclusion work done. Neil Ashford and our crew have been handling these jobs in Costa Mesa since 2011, from older ranch homes near Fairview Park to newer builds closer to South Coast Plaza. We’ll walk you through exactly what we find up there, what it costs, and what we do about it.
How Owens Corning Products Fail - and How We Fix Them
Rodents don’t care what brand of insulation you bought. But certain Owens Corning products fail in predictable ways when pests move in, and knowing the difference changes how we clean and restore your attic.
- Owens Corning EcoTouch Pink Fiberglas batts: Rats tunnel through the fluffy pink material to create nesting pockets, compressing the batts and destroying their R-value. The fiberglass fibers also trap urine and dander, which spreads odor through the house when air moves. We remove contaminated batts entirely, sanitize the deck, and install fresh material rather than trying to “clean” fiberglass that’s been used as a litter box.
- Owens Corning ProPink blown-in insulation: In Costa Mesa attics, blown-in ProPink settles over time, especially after roof leaks or rodent traffic create paths through it. Rodents burrow down to the drywall ceiling below, leaving tunnels that compromise the thermal barrier. We vacuum out the contaminated loose-fill, treat the space, and re-blow to proper depth, often improving on the original install.
- Owens Corning R-19 and R-30 kraft-faced batts: The kraft paper facing wicks moisture and rodent urine, and in older Costa Mesa homes it’s often stapled incorrectly, sagging into the soffit vents and blocking ventilation. That trapped moisture makes the attic more attractive to rodents seeking water. We pull sagging batts, correct the venting, and reinstall facing properly or switch to unfaced material where the local climate makes sense.
- Owens Corning AttiCat blown-in system: If the original contractor blew AttiCat too shallow to save money, the attic never hit its target R-value, which means the homeowner paid for performance they never got. That’s common in Costa Mesa homes built in the 1980s and 1990s. We measure existing depth, show you what’s actually up there, and bring it to code-current levels after cleaning and exclusion.
- Owens Corning Insulpink and older fiberglass lines still found in Costa Mesa: Pre-2000 Owens Corning fiberglass often has no rodent-resistant properties at all, and in attics near the Santa Ana River or Talbert Regional Park, rodent pressure is higher than most of Orange County. We see rat tunnels through these older lines routinely. The fix starts with sealing every penetration, from gable vents to plumbing stacks, before any new insulation goes in. Insulation alone never stops rodents.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
Here’s how an Owens Corning attic cleaning and rodent proofing job goes from first call to done right, with Neil Ashford’s standard applied the whole way.
- 1
Attic inspection and diagnosis: We map the contaminated zones, identify rodent entry points, check for water intrusion, and document what Owens Corning product is present and its condition. You get a straight report, not a scare pitch.
- 2
Removal of contaminated material: We use commercial HEPA-filtered vacuums to pull out rodent-soiled insulation, nesting debris, and old droppings. Fiberglass dust stays contained, not floating through your house.
- 3
Sanitizing and decontamination: We treat the deck and framing with a professional-grade antimicrobial and enzyme cleaner that breaks down urine residue and kills bacteria. This is the step most handymen skip.
- 4
Rodent proofing and exclusion: We seal entry points at the roofline, gable vents, soffit gaps, and utility penetrations using steel mesh, hardware cloth, and sealants that rats can’t chew through. This is the only part of the job that actually keeps them from coming back.
- 5
Fresh Owens Corning insulation: We reinstall Owens Corning EcoTouch or ProPink to proper depth and vent the soffits correctly. We also check for air leaks and seal those before insulating, because insulation without air sealing wastes money.
- 6
Final check and the 90-Day Done Right Promise: We walk you through what we did, reset any disturbed baffles, and leave the attic cleaner than we found it. If it’s not right within 90 days, we make it right. No fine print, no arguing.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Costa Mesa
Costs in Costa Mesa track with attic size, contamination severity, and how much exclusion work your roofline requires. Here’s what we see on typical Owens Corning jobs:
- Attic cleaning and sanitizing only: $950 to $1,500 for a standard 1,200 to 1,800 square foot attic with moderate contamination.
- Full cleanout with rodent exclusion: $1,800 to $2,400 when entry points need sealing at the roofline and soffits, and contaminated Owens Corning batts or blown-in material must be removed and replaced.
- Blown-in ProPink re-installation after cleanout: $1.50 to $2.25 per square foot, depending on target R-value and access. Your Costa Mesa home’s existing depth determines how much additional material you need.
What moves the price is access, the number of entry points, whether you have vaulted ceilings or a low-pitch roof, and how long the rodents have been active. We give upfront pricing before work starts, and most jobs are done in one visit. Call (657) 224-2897 for a free estimate and we’ll nail down your number.

FAQs
In most cases, no. Once rodents have nested in Owens Corning fiberglass or blown-in ProPink, the material is contaminated with urine, droppings, and dander that cannot be cleaned effectively. We remove and replace it. If the contamination is light and contained to one corner, we can sometimes spot-clean and treat the area, but you’ll get an honest assessment of what’s actually sanitary. Call (657) 224-2897 for an attic inspection and we’ll show you what we’re seeing.
No. Owens Corning warranties cover manufacturing defects, not damage from pests, water intrusion, or improper installation. Rodents void any practical warranty on the insulation, which is why exclusion matters more than the insulation itself. We work as an independent Owens Corning service provider and we’ll never pretend a warranty covers something it doesn’t. We install fresh Owens Corning material with our own 90-Day Done Right Promise on the labor.
Most Costa Mesa jobs are scheduled within a few days, and the work itself is typically completed in a single visit, usually four to seven hours depending on attic size and contamination. Call (657) 224-2897 and a live person will give you an honest schedule, no voicemail tag.
Almost never, in Costa Mesa. Adding new Owens Corning ProPink on top of rodent-soiled material locks in the odor, the bacteria, and the damaged thermal barrier. You’ll pay more in the long run when we have to remove twice the material. Better to clean and restore the attic properly once.
Yes. We keep emergency slots for active rodent problems in Costa Mesa, especially during the cooler months when rats move into attics near Fairview Park and the Talbert Regional Park corridors. Call (657) 224-2897 and we’ll get a tech out to seal the entry points and start the cleanout as fast as possible.
