Owens Corning Attic Cleaning & Rodent Proofing in Round Rock: What to Know First
We provide independent Owens Corning attic cleaning and rodent proofing in Round Rock, with most jobs completed in one day and a written price delivered before any work starts. Typical attic cleanouts with rodent exclusion run $1,800-$3,400 for homes in the 1,500-2,500 square foot range common to neighborhoods like Behrens Ranch and Fern Bluff. This page is for Owens Corning homeowners who’ve found droppings, nesting material, or compressed insulation in their attic and want the problem handled without voiding their material warranty.

How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles unevenly after rodent tunneling. The PINK Fiberglas Loosefill Insulation (L77) holds its R-value when intact, but rats and squirrels carve runways through it, creating bare spots over top plates where conditioned air escapes. We remove the contaminated material, seal the bypasses with fire-rated caulk and rigid foam, then reinstall to the original R-49 specification with fresh AttiCat product or equivalent.
- Owens Corning ProCat loosefill becomes a nesting substrate when attic humidity climbs above 60 percent. In Round Rock’s spring and fall, when overnight lows drop into the 50s but daytime attic temps spike, rodents seek the thermal mass of undisturbed fiberglass. We find this most often in older homes near Old Town where gable vents were never supplemented with ridge ventilation. Our fix: sanitize the space, install stainless steel mesh at all entry points, and verify airflow with a smoke pencil before closing up.
- Owens Corning Raft-R-Mate baffles collapse when chewed, blocking soffit intake. The corrugated polypropylene baffles are lightweight and effective until squirrels gnaw through them; once compromised, they fall against the top plate and choke off ventilation. We replace damaged baffles with metal-reinforced equivalents and screen the soffit openings with 1/4-inch hardware cloth - a detail many Round Rock roofers skip because it’s invisible from the ground.
- Owens Corning Foamular rigid board at attic hatches gets urine-soaked and structurally degraded. The extruded polystyrene insulation used in hatch covers absorbs rodent urine rather than wicking it, creating a persistent odor source and compressing the R-10 value the manufacturer specifies. We remove the contaminated board, treat the substrate with an enzymatic cleaner, and reinstall with a fresh Foamular piece sealed to the frame with weatherstripping - not duct tape, which is what we usually find.
- Owens Corning QuietZone acoustic batts in bonus-room knee walls become rodent highways. The denser, softer fiberglass batts installed for sound control between finished attic spaces and exterior walls are easier for mice to compress into nests than standard thermal batts. We see this in Round Rock’s newer construction near Paloma Lake where bonus rooms were finished with Owens Corning systems. Our approach: remove and dispose of contaminated batts, seal the wall baseplates to the subfloor with acoustic sealant, then reinstall with new QuietZone protected by interior access panels.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
- 1
Written price first. We inspect the attic, document contamination with photos, and deliver a flat price before any work starts - Haven Standard Clause 1. No exceptions.
- 2
Contamination assessment and material identification. We confirm which Owens Corning product lines are present, check for warranty documentation, and note any OEM-specific installation requirements that affect how we proceed.
- 3
Removal and sanitizing. Contaminated insulation comes out in bagged loads. We apply a hospital-grade disinfectant to all attic surfaces, paying attention to the odor-absorbing characteristics of fiberglass versus cellulose - Owens Corning fiberglass doesn’t hold odor the same way, but the dust load is different and requires HEPA filtration during extraction.
- 4
Rodent proofing and air sealing. Every entry point larger than 1/4 inch gets stainless steel mesh, copper wool, or concrete patch depending on the substrate. Top plates, can lights, and plumbing penetrations are sealed before any new material goes in. Seal the leaks first. The insulation has nowhere to go until you do.
- 5
Reinstallation with documentation. We reinstall to the original R-value specification using Owens Corning or equivalent materials sourced through our supplier network. Every job closes with a Documented Photo Record and, where applicable, before-and-after blower-door readings showing the actual air-sealing improvement.
- 6
365-Day Done Right Promise activation. The written warranty and scope go to you before the crew leaves. If rodents re-enter through our work within a year, we return and fix it.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Round Rock
| Scenario | Typical Range |
|---|---|
| Attic cleanout + sanitizing only (no rodent entry) | $900-$1,400 |
| Cleanout + rodent proofing + Owens Corning reinstall to R-38 | $2,200-$3,200 |
| Cleanout + proofing + reinstall to R-49 with air sealing | $2,800-$4,100 |
| Heavy contamination (multiple species, structural damage) | $3,500-$5,500 |
What moves the price: attic square footage, depth of existing Owens Corning material, number of penetrations to seal, accessibility (steep pitches add labor), and whether the HVAC handler is in the attic requiring containment protocols. Homes in Round Rock’s Forest Creek area with 12:12 roof pitches and complex dormers run toward the higher end. We also service Reflectix radiant barrier systems when those are present and damaged. Call (737) 259-7528 - estimates are free, and we provide a Free Second Opinion on any written estimate you’ve already received.
Why Round Rock Homeowners Call Topside Attic Insulation Round Rock for Owens Corning Work
We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve sealed and insulated over 9,000 homes - every one with a written price first and a documented record at the end. Wes Okafor and our crew have worked Owens Corning systems across Williamson County long enough to know that the L77 loosefill in a 2018-built Round Rock home behaves differently after rodent damage than the ProCat in a 2022 build. We don’t guess. We test, seal, insulate, and prove the result with numbers you can keep. Our 365-Day Done Right Promise is in writing before anyone starts. Calls are answered by a live person, 24/7.
FAQs
The Owens Corning limited warranty covers manufacturing defects, not damage from pests or environmental conditions - so rodent contamination itself isn’t a warranty claim. However, reinstalling with non-Owens Corning products or improper installation technique can void remaining coverage on adjacent original material. We document what was removed, what was reinstalled, and whether OEM or equivalent products were used so you have a record if warranty questions arise later. Call (737) 259-7528 and we’ll review your specific warranty documents during the estimate.
Most jobs in Round Rock finish in one day for attics under 1,500 square feet; larger or heavily contaminated spaces may need two days. We don’t rush the sanitizing phase - fiberglass dust and rodent-borne pathogens require full dwell time for the disinfectant. You’ll get a specific schedule in your written scope, not a window. Call (737) 259-7528 to book.
If the material is less than five years old, localized removal and spot replacement can work - but we rarely see this in practice. Rodent urine penetrates fiberglass batts and loosefill beyond what’s visible; compressed or tunneled areas don’t recover their original R-value. We recommend full removal and reinstall when contamination covers more than 15 percent of the attic floor or when odor persists after surface treatment. The written price we deliver breaks out both options so you decide with actual numbers.
We source Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber through regional distributors in Austin and San Antonio - no proprietary lock-in, no waiting for single-brand shipments. For standard Owens Corning loosefill and batt products, we typically have next-day availability. Specialized items like Foamular board in non-standard thicknesses may take 48-72 hours. We’ll tell you exactly what’s in stock when we deliver the written price.
We warranty our exclusion work for 365 days under the Done Right Promise. The proofing holds if three conditions are met: all entry points 1/4 inch or larger are sealed, the attic is no longer attractive as habitat (which means proper ventilation and no food sources), and neighboring properties aren’t generating new pressure. We can’t control your neighbor’s tree canopy or construction disturbances, but we can make your attic the hardest target on the block. Our Documented Photo Record shows every sealed point so you know what was done. Call (737) 259-7528 to schedule.
