Owens Corning Attic Cleaning & Rodent Proofing in Boerne: What to Know First
As an independent Owens Corning service provider, we handle attic cleaning and rodent proofing for Boerne homeowners with Owens Corning insulation systems, most jobs completed in one to two days with a written price delivered before any work starts. Typical attic cleanout and rodent exclusion with Owens Corning restoration runs $1,800 to $4,200 in the Boerne market, depending on contamination level and whether the attic floor needs full re-insulation after sealing. This page is for owners of Owens Corning AttiCat, ProCat, or QuietZone products who’ve found droppings, nesting material, or compressed insulation in their attic and need the problem fixed without voiding their existing warranty coverage. Call (830) 529-7780 to schedule a free estimate with a written scope.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Loose-Fill compression from rodent traffic. The blown fiberglass settles into pathways where rats and squirrels run repeatedly, creating bare spots that read as R-19 or lower on thermal imaging even when the original install called for R-38. We remove the contaminated layer, sanitize the deck, install exclusion barriers at eave and ridge vent intersections, then blow fresh AttiCat to manufacturer depth specifications measured with a ruled probe, not eyeball estimation.
- ProCat Professional Series odor retention in porous glass fibers. Unlike cellulose, which can sometimes be surface-treated and left in place, Owens Corning’s ProCat holds urine salts deep in the fiber matrix; the ammonia off-gassing returns on humid Hill Country afternoons when attic temperatures drop below 110°F. We bag and remove all ProCat in contaminated zones, apply an enzymatic treatment to the substrate, and reinstall only after blower-door confirmation that entry points are sealed - “Seal the envelope first. Then fill it.”
- QuietZone Noise Control Batts shredded for nesting material. The denser, more rigid batt structure that absorbs sound between floors also holds its shape when chewed, making it preferred nesting substrate for roof rats in Boerne’s oak-canopied neighborhoods near River Road Park. We document the damage with photos for insurance, remove soiled batts, and replace with fresh QuietZone only after steel mesh exclusion is installed at all plumbing and electrical penetrations larger than 1/4 inch.
- FOAMULAR rigid board degradation from rodent grease trails. Owens Corning’s XPS board used in attic access hatches and knee walls develops a hydrophobic surface film from rodent sebaceous glands that repels future adhesive and tape applications. We cut out the affected boards, replace with fresh FOAMULAR, and install metal flashing at the hatch perimeter that rodents can’t grip - a detail we learned from a 2019 job on a 1980s home off Balcones Creek where the original hatch was re-chewed twice before we got the call.
- WeatherLock G granule loss from accumulated droppings. When rodent waste builds up on Owens Corning’s self-sealing ice and water barrier used in some attic-to-roof transitions, the granules separate and the asphalt core becomes tacky, attracting more debris and creating a thermal bridge. We clean the membrane with manufacturer-approved solvents, assess granule retention, and replace sections where the mineral surface is more than 30 percent compromised - a threshold we verify by comparison against an unexposed sample from our stock.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
- 1
Written price and scope before arrival. We email a flat price based on attic square footage, contamination level from your photos, and Owens Corning product type - no “we’ll see when we get there.”
- 2
Blower-door test and entry mapping. We pressurize the house to locate active air leaks that rodents are using as highways; in Boerne’s limestone hill country, gaps at chimney chases and recessed can lights are the usual suspects.
- 3
Contaminated material removal and documentation. Crews in respirators bag all soiled Owens Corning insulation, photographing each stage for your records and any insurance claim.
- 4
Substrate sanitizing and structural repair. Enzymatic treatment of decking, replacement of chewed wiring insulation (we coordinate with our electrician), and installation of galvanized steel exclusion mesh at all identified entry points.
- 5
Re-insulation with matched Owens Corning product. We source AttiCat, ProCat, or QuietZone through our supplier - same SKU family, never a generic substitute - and install to the depth marked on your original spec card or to current IECC code if none exists.
- 6
Post-work blower-door and photo record delivery. You get the pressure-differential report in pascals, before-and-after CFM50 numbers, and a link to your documented photo record within 24 hours of crew departure.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Boerne
Most attic cleaning and rodent proofing jobs in Boerne homes with Owens Corning insulation run between $1,800 and $4,200. Light contamination under 500 square feet with spot re-insulation typically falls at the lower end; full AttiCat removal across 1,200 square feet with deck replacement and complete re-blow pushes toward the upper range. Three factors move the price: how much Owens Corning product must be removed and replaced, whether rodent entry requires roof-level exclusion work beyond standard eave sealing, and if electrical or HVAC duct damage needs coordinated repair. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly. Every estimate is flat-priced in writing before work starts - call (830) 529-7780 for yours.
Why Boerne Homeowners Call Topside Attic Insulation Boerne for Owens Corning Work
Wes Okafor has run blower-door tests on Owens Corning systems in Boerne homes for going on eighteen years, including that stretch of older construction near the Cibolo Nature Center where stack-effect leakage was destroying cooling performance before insulation ever entered the conversation. Our 365-Day Done Right Promise covers all completed work, backed by a written scope and warranty delivered before the first tool comes off the truck. Calls are answered by a live person 24/7, technicians are background-checked and uniformed, and we publish before-and-after blower-door numbers on every job where air sealing is performed - no exceptions. We source Owens Corning materials through standard distribution channels alongside Johns Manville, Knauf, and other brands, so we’re never locked into pushing one product line when another fits your assembly better.
FAQs
No - rodent damage is not a product defect, so it doesn’t trigger the Owens Corning limited warranty, but the warranty also won’t cover replacement of contaminated material. We document the damage source separately from product failure and install new Owens Corning product with its own install-date coverage. Call (830) 529-7780 and we’ll review your original warranty terms during the free estimate.
We source current-production Owens Corning AttiCat, ProCat, QuietZone, and FOAMULAR through our distributor - same SKUs, not aftermarket substitutes. For discontinued lines, we match density and R-value with the closest current Owens Corning equivalent and note the substitution in your written scope. We don’t use bagged big-box AttiCat for professional install jobs; the product spec differs from contractor-grade ProCat in fiber diameter and settling rate.
For moderate contamination with intact Owens Corning product, cleaning and spot replacement is usually 30 to 40 percent less than full removal and switch to spray foam or cellulose. But if the attic floor was never air-sealed - common in Boerne builds from 2005 to 2015 - the better long-term value is often full removal, proper sealing, and re-install with fresh Owens Corning to current depth. We price both paths in writing so you can compare.
Most single-attic jobs are completed in one to two working days from crew arrival. We can typically schedule within three to five business days during non-peak months; June through September in Boerne runs closer to seven to ten days due to cooling-season demand. Emergency situations with active rodent entry and HVAC contamination get prioritized - call (830) 529-7780 and we’ll slot you based on severity.
We don’t price-match; we provide a free second opinion on any written estimate instead. Bring us another contractor’s scope and we’ll read it with you, line by line, and explain where the material specs, air-sealing detail, or warranty terms differ from what we propose. The Haven Standard requires that we deliver our own written price before any work starts - we won’t start from someone else’s number.
