We provide independent Owens Corning attic cleaning and rodent proofing in Cedar Park, typically completing jobs in one to two days with a written price delivered before any work starts. Most Cedar Park homeowners with Owens Corning insulation systems pay between $1,800 and $4,200 for full attic cleaning, sanitizing, and rodent exclusion, depending on attic square footage and contamination level. This page is for Owens Corning owners in Cedar Park who’ve found droppings, nesting material, or compressed insulation in their attics and want the problem fixed without voiding whatever warranty coverage remains.

How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles unevenly after rodent traffic. The PINK Fiberglas Insulation (LooseFill) that our crews encounter most often in Cedar Park’s 1990s-2010s builds compresses to roughly half its labeled R-value when rats run repeated paths between joists. We remove the contaminated loose fill, seal every penetration with fire-rated caulk and steel mesh, then reinstall to original depth specifications with fresh Owens Corning blown-in or an alternative if the homeowner prefers.
- Owens Corning ProCat series shows grease staining that standard vacuuming won’t lift. The higher-density ProCat Professional Loose Fill Fiberglas Insulation used in many Cedar Park energy-efficient builds from 2012 onward traps rodent sebum deep between bonded fibers. Surface cleaning leaves odor trails that attract new rodents. We extract all ProCat material, apply enzyme-based decontamination to the substrate, and reinstall only after blower-door verification that entry points are sealed.
- Owens Corning Foamular rigid board at attic hatches warps from urine saturation. The extruded polystyrene insulation we find insulating pull-down stairs in Cedar Park’s Ranch at Deer Creek and Cypress Mill homes delaminates when rodents nest against the warm side. We replace with new Foamular only after installing a continuous metal flashing barrier, or spec Rockwool Comfortboard if the homeowner wants rodent-proof material from the start.
- Owens Corning Raft-R-Mate baffles collapse under nesting weight. These vent baffles - the foam channels that keep soffit airflow open above your insulation - crack when squirrels pack cedar elm twigs and leaves from Cedar Park’s canopy against them. A broken baffle blocks intake ventilation, and in July that attic hits 140°F. We replace with rigid Raft-R-Mate or upgrade to site-built baffles from corrugated plastic if the roof pitch is shallow.
- Owens Corning EcoTouch batts shred where rodents tunnel for nesting material. The Kraft-faced batts common in Cedar Park’s older sections near Buttercup Creek become confetti when mice pull fibers for nest building, exposing drywall and creating fire hazards near can lights. We remove shredded batts, air-seal top plates and electrical penetrations with fire-blocking foam, then reinstall EcoTouch or switch to unfaced batts with a separate vapor retarder if moisture readings warrant it.
Our Owens Corning Attic Cleaning & Rodent Proofing Process

- 1
Written price and scope before we enter the attic. We inspect from the hatch with a borescope camera, document contamination extent, and deliver a flat price with line-item breakdown. No work starts without your signature on the scope.
- 2
Containment and negative-air setup. We seal the attic access with a temporary poly airlock and run HEPA-filtered negative air to prevent cross-contamination into living space. This matters in Cedar Park’s tight-built homes from the last decade where HVAC return ducts run through attic plenums.
- 3
Material extraction by type. Owens Corning loose fill goes into sealed bags by R-value depth so we know what to replace. Batts are rolled and bagged by location. We note any OEM labels for warranty documentation.
- 4
Substrate decontamination and air sealing. Enzyme treatment on plywood, followed by sealing all top plates, wire penetrations, and can lights with fire-rated materials. We run a blower-door test here - measuring CFM50 before and after - so you see the leakage reduction in actual numbers.
- 5
Rodent exclusion with steel and concrete. Every entry point larger than ¼ inch gets 19-gauge galvanized steel mesh, hydraulic cement, or copper wool depending on substrate. We map each repair on your photo record.
- 6
Reinstallation, final test, and documentation. Fresh Owens Corning or alternative insulation to specified depth. Final blower-door reading. You receive: written scope completion, before-and-after photos, ACH50 numbers, and our 365-Day Done Right Promise in writing.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Cedar Park
Most Owens Corning attic cleaning and rodent proofing jobs in Cedar Park fall between $1,800 and $4,200. Here’s what moves that number:
- Attic size under 1,200 sq ft, light contamination: $1,800-$2,600
- Attic size 1,200-2,000 sq ft, moderate rodent activity with partial insulation replacement: $2,600-$3,400
- Attic size over 2,000 sq ft, heavy contamination, full insulation removal and reinstall: $3,400-$4,200+
Add $400-$800 if we find degraded Owens Corning Foamular board at hatches or stairs that needs replacement. Cedar Park’s limestone substrate sometimes forces us to use specialized masonry anchors for exterior exclusion work, adding $200-$350 to jobs in the Ranch at Brushy Creek or similar developments built on caliche. Every estimate includes free removal of contaminated material and disposal. We also service Reflectix radiant barrier systems when they’re part of the assembly. Call (737) 245-6428 - estimates are free, and we deliver a written price before any work starts.
Why Cedar Park Homeowners Call Topside Attic Insulation Cedar Park for Owens Corning Work

We’re an independent Owens Corning service provider - not affiliated with the manufacturer - which means we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, and others based on what your specific assembly needs, not a corporate product mandate. Since 2016, we’ve sealed and insulated over 9,000 homes, every one with a written price first and a documented photo record at completion. Our 365-Day Done Right Promise applies to all attic cleaning and rodent proofing: if rodents re-enter through our exclusion work, we return and fix it. Calls to (737) 245-6428 are answered by a live person 24/7. Wes Okafor trains every technician on blower-door fundamentals - the same pressurization testing he learned at Olive-Harvey College’s building science program - because an attic that’s cleaned but still leaky will have the same problems again.
FAQs
Removing and reinstalling Owens Corning insulation does not void the limited product warranty, but damage caused by rodents, moisture, or improper installation is excluded from coverage regardless of who cleans it. We document original product labels and installation conditions so you have records if a future claim arises. Call (737) 245-6428 and we’ll review what’s covered during your free estimate.
We source genuine Owens Corning loose fill, batts, and rigid board through standard distribution channels, and we also spec quality alternatives like Rockwool or Knauf when the assembly calls for different performance characteristics. We never use “compatible” off-brand materials without your written approval. Your estimate lists every product by manufacturer and model.
When contamination exceeds roughly 30% of attic area, or when rodent urine has saturated the insulation substrate, full removal and replacement is usually more cost-effective than spot cleaning - you’re paying for labor twice if the restored sections fail within two years. We tell you which side of that line your attic falls on during the initial inspection, with photos. Estimates are free.
Most jobs are completed in one to two working days; heavily contaminated attics over 2,500 square feet may run into a third day. We schedule within 48 hours of your call for non-emergency work, and same-day response is available for active infestations where rodents are still accessing living space. Call (737) 245-6428 to check current availability.
We coordinate with licensed pest control operators for active trapping when needed, but our scope is the structural exclusion and insulation restoration - sealing entry points, removing contaminated material, and reinstalling to spec. We can recommend Cedar Park pest control partners we’ve worked with, or coordinate with your existing exterminator. The written scope defines exactly where our work ends and theirs begins.
