Owens Corning Attic Cleaning & Rodent Proofing in Tustin: What to Know First
Most Owens Corning attic insulation systems in Tustin that need cleaning and rodent proofing can be restored in one to two days, with written pricing provided before any work starts. As an independent Owens Corning service provider, we handle everything from contaminated AttiCat blown-in removal to full attic restoration with new Owens Corning ProPink or EcoTouch batts. Typical jobs in Tustin Legacy and the older neighborhoods near Old Town run $2,400-$5,800 depending on contamination level and square footage. Call (657) 286-7673 for a written estimate - we answer live, 24/7.
This page is for homeowners who can name the Owens Corning product in their attic, or at least know the pink insulation was installed by a previous owner, and need someone who understands how that specific material behaves after rodents, moisture, or years of compression.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Fiberglas Blown-In compacts unevenly after rodent nesting. The loose-fill product settles into tunnels and burrows, creating hard-packed ridges with bare spots underneath. We remove the contaminated layer entirely, then reinstall to a measured R-38 depth using a conditioned attic calculator - not eyeballing it from the hatch.
- EcoTouch batts delaminate when saturated with rodent urine. The brown kraft facing separates from the glass fiber core, and the binder breaks down. In Tustin’s warm, dry climate this often goes unnoticed until a home inspection flags it. We pull the degraded batts, HEPA-vacuum the joist bays, and install fresh unfaced batts if the roof deck ventilation is adequate.
- ProPink L77 loose-fill migrates away from eaves in homes with poor air sealing. Wind washing through soffit vents pushes the lightweight material toward the center of the attic, leaving thermal gaps at the perimeter. Wes Okafor’s crew seals the top plates and vent baffles first - “Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can.” - then redistributes or replaces the L77.
- Owens Corning Foamular rigid board shrinks at cut edges when exposed to attic heat cycling. In Tustin, where attic temperatures regularly hit 140°F in August, the XPS boards pull back from framing members, creating convection channels. We find this most often in platform-framed additions from the 2000s. Our fix: remove the compromised boards, seal the rim joist with closed-cell spray foam, then reinstall Foamular only where it serves a specific thermal break purpose.
- RadiantBarrier branded products accumulate rodent grease and lose reflectivity. The aluminum surface becomes dull and pitted where rats travel repeatedly. Cleaning doesn’t restore the emissivity value; we replace the degraded sections and install exclusion barriers at the same time.
Our Owens Corning Attic Cleaning & Rodent Proofing Process

- 1
Written price before entry. We inspect the attic hatch, document the Owens Corning product type and condition with photos, and deliver a flat price. No work starts without a signed scope.
- 2
Containment and HEPA extraction. The crew sets up negative air pressure, removes all contaminated insulation, and vacuums joist bays and decking. We bag Owens Corning batts separately from loose-fill for proper disposal - the binders differ, and California waste streams treat them differently.
- 3
Sanitizing and decontamination. We apply an enzyme treatment to break down rodent urine proteins, then a botanical disinfectant. The attic must read below 15% moisture content on our pin meter before any new material goes in.
- 4
Exclusion and air sealing. Every penetration, top plate gap, and can light gets sealed. We use Owens Corning joint sealant or equivalent fire-rated caulk where code requires it, and steel mesh for rodent barriers - never foam alone, which they chew through.
- 5
Reinstallation with documented depth and coverage. New Owens Corning or, if the homeowner prefers, Reflectix or another brand product is installed to the specified R-value. We photograph the completed depth gauge, the exclusion work, and the final condition.
- 6
Delivery of record. The homeowner receives a Documented Photo Record, the written warranty, and - on jobs where air sealing was performed - before-and-after notes on the building envelope condition.

AfterWhat Owens Corning Attic Cleaning & Rodent Proofing Costs in Tustin
These are real ranges from jobs we’ve completed in Tustin and Tustin Legacy over the past two years:
| Scenario | Typical Range |
|---|---|
| AttiCat removal, sanitize, reinstall to R-38 (1,200 sq ft attic) | $2,400 - $3,600 |
| EcoTouch batt removal with kraft facing degradation, full replacement | $3,200 - $4,800 |
| Heavy rodent contamination: removal, sanitize, exclusion, reinstall | $4,200 - $5,800 |
| Partial restoration with Foamular board replacement at rim joists | Add $800 - $1,400 |
What moves the price: square footage, contamination depth (one season of mice versus years of rats), accessibility (vaulted ceilings with limited hatch access), and whether the existing product can be recycled or must go to landfill. We also handle Reflectix systems and can quote a switch if the homeowner wants to compare.
Every estimate is free, written, and valid for 30 days. Call (657) 286-7673.
Why Tustin Homeowners Call Topside Attic Insulation Tustin for Owens Corning Work

We’ve been in a lot of Tustin attics since 2016 - the post-redevelopment builds in Tustin Legacy with their complex rooflines, the 1960s ranch homes near Browning Avenue with original insulation that’s seen multiple rodent generations. We don’t promise “Owens Corning certified” because we’re not; we’re independent, and that means we can source from Johns Manville, Knauf, Rockwool, or Reflectix if that better serves the job.
What we do promise: a written price before anyone climbs the ladder, a 365-Day Done Right Promise backed by a written warranty, and a live person on the phone whenever you call. Our technicians are background-checked, uniformed, and trained to document - not upsell. The photo record you get at the end belongs to you, not our marketing department.
FAQs
No - Owens Corning’s limited warranty on insulation products covers manufacturing defects, not installation or maintenance by third parties. The warranty was already voided if rodents contaminated the material, since that’s excluded under normal use. We document the pre-existing condition with photos so there’s no dispute about when the damage occurred. Call (657) 286-7673 if you need help reading your warranty language.
We source Owens Corning ProPink, EcoTouch, and AttiCat directly through authorized distributors in Orange County, so the product is identical to what was originally installed. For some specialized applications - Foamular at unusual thicknesses, for example - we may substitute an equivalent from Knauf or Johns Manville with the homeowner’s written approval. We never install “compatible” loose-fill that doesn’t match the specified thermal performance.
If the contamination is surface-level (recent mouse activity, no urine saturation into the batt core) and the insulation isn’t compressed below 80% of its labeled thickness, cleaning and spot replacement usually works. If the kraft facing is delaminated, the glass fibers are bonded together with waste, or the depth has settled below R-30 equivalent, full removal and replacement is the only code-compliant path. We test with a moisture meter and depth gauge during the estimate, then show you the numbers.
Most estimates happen within 48 hours of your call, and scheduling for the work itself is typically within one week. Emergency situations - active rodent infestations with HVAC contamination, or a home sale pending inspection - can sometimes be expedited. We answer live at (657) 286-7673 to check current availability.
We handle exclusion as part of the insulation restoration - sealing entry points with steel mesh, concrete patch, and hardware cloth where rodents have breached the envelope. We don’t set traps or apply rodenticide; if active infestation is present, we coordinate with your pest control company or can recommend one. Our scope ends at a rodent-proof attic with restored insulation and documentation that the work was done.
