This page is for homeowners in Seguin neighborhoods near Guadalupe Regional Medical Center, McQueeney, and the older Hill Country subdivisions where Owens Corning AttiCat blown-in fiberglass and ProCat loose-fill systems were installed from the mid-2000s through the 2020s. If you’ve found droppings, noticed compressed insulation, or smelled something coming from your attic hatch, we can tell you exactly what’s happening and what it’ll take to fix it.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Fiberglass compression from rodent traffic. The blown-in AttiCat system relies on loft to hit its R-value target, but rodent pathways through Seguin attics pack the fibers into gray trails that read 30-40% lower on thermal imaging. We remove the contaminated batts, vacuum the droppings, and reinstall fresh Owens Corning ProCat or an equivalent loose-fill after sealing entry points - never over the old, compressed layer.
- ProCat loose-fill settling around top plates and wire penetrations. Owens Corning ProCat is designed to resist settling, but in Seguin’s humidity-cycling climate the material can shift away from air leaks that rodents then exploit as highways. We pull back the ProCat, seal the top plates and electrical penetrations with fire-rated caulk and steel wool, then redistribute or replace the insulation. The blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - tells us if we got it.
- Owens Corning Foamular rigid board degradation from raccoon nesting. Foamular XPS boards in Seguin attic knee walls attract raccoons seeking denning sites; the animals tear corners and compress the boards, creating cold spots that show up as 15-20 degree differentials on infrared. We remove damaged Foamular sections, sanitize the substrate, and replace with new Foamular or an equivalent rigid board after installing exclusion barriers.
- PINK Fiberglass batt contamination from roof rat urine. Standard Owens Corning kraft-faced batts in pre-2010 Seguin homes absorb roof rat urine, which crystallizes and continues off-gassing even after the animals are gone. We remove all contaminated batts, HEPA-vacuum the decking, apply an enzymatic decontamination treatment, and install fresh unfaced batts or blown-in - never reusing material that held biological contamination.
- AttiCat system compromised by contractor-grade installation over unsealed can lights. We see this in Seguin tract homes from the 2015-2020 boom: AttiCat blown directly over non-IC-rated can lights, creating heat traps that draw rodents and create fire risk. We remove the insulation around each fixture, install proper fire-rated covers or replace with IC-rated LEDs, seal the thermal bypass, then reinstall fresh Owens Corning or equivalent material. The report goes home with you - the numbers do the talking.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
- 1
Written price before arrival. We review photos or conduct a brief site visit in Seguin, then deliver a flat-price scope in writing. No work starts without it.
- 2
Blower-door baseline and attic documentation. We run the pressurization test, photograph the Owens Corning product condition, and map rodent entry points, insulation compression, and contamination zones.
- 3
Removal and decontamination. Contaminated Owens Corning material comes out; we HEPA-vacuum, apply enzymatic sanitizer, and let the deck dry before any new material goes in.
- 4
Air sealing and rodent exclusion. Top plates, penetrations, and entry gaps are sealed with appropriate materials - steel mesh for rodents, fire-rated caulk for thermal bypasses. This happens before insulation, always.
- 5
Material replacement and verification. We install fresh Owens Corning ProCat, AttiCat, or equivalent spec’d to the original R-value or higher, then run a post-work blower-door test to document the improvement.
- 6
Photo record and warranty delivery. You receive a Documented Photo Record of the entire process, the pre- and post-blower-door readings, and the 365-Day Done Right Promise in writing.
Before
AfterWhat Owens Corning Attic Cleaning & Rodent Proofing Costs in Seguin
Most attic cleaning and rodent proofing jobs on Owens Corning systems in Seguin run between $1,800 and $4,200. What moves the price:
- Attic size and accessibility: A 1,200 sq ft attic with a standard hatch runs lower; finished attics with kneewalls or limited access add labor hours.
- Contamination level: Light rodent traffic with localized droppings versus heavy infestation requiring full removal, deck sanitization, and odor treatment.
- Insulation replacement: Cleaning and reusing salvageable Owens Corning material versus full removal and new ProCat or AttiCat installation.
- Entry point complexity: Three to four standard roofline gaps versus multiple soffit breaches, chimney gaps, or HVAC penetrations requiring ladder work.

Why Seguin Homeowners Call Topside Attic Insulation Seguin for Owens Corning Work
We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Seguin follow a pattern: older framing near the hospital district, newer construction toward McQueeney with contractor-grade shortcuts, and everywhere the Hill Country humidity cycling that tests every building envelope. Wes Okafor and our crew know Owens Corning’s product line from hands-on work, not catalog browsing - we can tell you whether your AttiCat system is worth salvaging or whether the rodent damage means starting fresh.
Our 365-Day Done Right Promise applies to every job, and we publish before-and-after blower-door numbers so you can verify the air-sealing result yourself. We also service Reflectix and other major brands, so if your attic has mixed materials from multiple installs, we won’t force a single-brand solution that doesn’t fit. Calls are answered by a live person 24/7 - no voicemail loops, no callback windows measured in business days.
FAQs
No - proper cleaning and reinstallation by a qualified technician does not void Owens Corning’s product warranty, though damage caused by rodents or improper handling is not covered by Owens Corning. We document product condition with photos before we start so there’s a clear record. Call (830) 549-6646 if you need help understanding your coverage.
We source Owens Corning ProCat, AttiCat, and Foamular directly through standard distribution channels, and we also use quality equivalent materials from Johns Manville, Knauf, and Rockwool when the job spec or availability calls for it. We’ll tell you exactly what’s going in and why before we start - no proprietary lock-in. For an exact material list on your job, call for a written estimate.
Cleaning and reusing lightly contaminated blown-in fiberglass can save $400-$800 on a typical Seguin attic, but if the material is compressed, urine-contaminated, or disturbed by heavy rodent traffic, replacement is the only safe option and saves you from redoing the job in two years. We assess this during our initial documentation and give you both prices in writing. Call (830) 549-6646 for an evaluation.
We typically schedule inspections within 24-48 hours in Seguin and surrounding areas, and most cleanout and proofing jobs start within a week of written approval. Emergency situations with active infestations or exposed wiring get priority scheduling. A live person answers calls 24/7 at (830) 549-6646.
Adding new insulation over rodent-contaminated or compressed material traps odors, reduces the effective R-value, and violates basic building science - we won’t do it. The correct sequence is remove, seal, sanitize, then install fresh material. Anything else is a temporary fix that costs more long-term. Call for a written scope and price before any work starts.
