Owens Corning Attic Cleaning & Rodent Proofing in San Antonio: What to Know First
Owens Corning attic cleaning and rodent proofing in San Antonio typically runs $1,200 to $3,800 depending on attic size, contamination level, and how much exclusion work is needed. Most jobs are completed in one to two days, and we work as an independent Owens Corning service provider, which means we can repair or replace damaged material without voiding any remaining manufacturer warranty. If you’ve got rodents in your attic and Owens Corning insulation up there, call (866) 751-4428 and we’ll give you a straight answer on what it’ll take to fix it. This page is for San Antonio homeowners who own Owens Corning insulation, specifically ProPink blown-in fiberglass or R-19/R-30 batt products, and have discovered droppings, nesting, or chewed material. We answer the phone live, day or night.
How Owens Corning Products Fail - and How We Fix Them
Owens Corning makes solid insulation, but no product is rodent-proof. Here’s what we see in San Antonio attics and how we handle each one.
- ProPink blown-in fiberglass gets tunneled and compressed. Rats and squirrels burrow through blown-in ProPink looking for warmth, leaving trails that crush the insulation down to half its R-value. We remove the contaminated material, sanitize, and blow in fresh Owens Corning ProPink to the correct depth for San Antonio’s climate zone.
- R-19 and R-30 kraft-faced batts become nesting material. The paper facing on Owens Corning batt insulation is exactly what rodents want for nests. They shred the facing, pull batts apart, and leave urine-soaked piles in one corner. We remove the damaged batts, treat the decking, and install new faced batts with the vapor barrier oriented correctly for a vented Texas attic.
- ProPink blown-in insulation hides rodent activity until it smells. Because blown-in ProPink sits loose and deep, droppings and urine soak down into the material where you can’t see them. The first sign is usually an ammonia smell on a hot San Antonio afternoon. We do a full attic cleanout and sanitizing with an enzyme-based treatment that breaks down the odor at the source.
- Owens Corning EcoTouch batts get compressed by raccoons and opossums. Larger animals flatten EcoTouch batts to create sleeping spots, and compressed fiberglass loses most of its insulative power. We remove the flattened sections, reinstall fresh EcoTouch or ProPink, and seal the entry point so the animal can’t get back in.
- Rodents chew through Owens Corning ProPink bags and leave exposed fiberglass. If the original installer left partial bags in the attic, rodents shred them and scatter loose fiberglass across the decking. We remove all debris, bag it, and haul it off, then vacuum the entire attic floor before installing anything new.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
Here’s how a typical Owens Corning attic cleaning and rodent proofing job goes from the first call to the final walkthrough.
- 1
You call, a real person answers. We ask about the signs you’re seeing: droppings, scratching sounds at night, smells, or visible damage. We schedule a visit, and there’s no trip charge if you’re inside our service county.
- 2
We inspect the attic and identify the entry points. Rodents rarely enter through the same hole twice, but they do follow the same paths. We check soffits, roof vents, gable ends, and pipe penetrations. We also assess how much Owens Corning material is contaminated beyond saving.
- 3
We remove contaminated insulation and sanitize. The damaged ProPink or EcoTouch comes out first. Then we vacuum the decking, apply an enzyme-based sanitizer to the affected areas, and check the ductwork for chewing or droppings.
- 4
We seal entry points and install exclusion barriers. We use galvanized mesh, foam sealant, and flashing to close every hole a rodent can fit through, which is anything wider than a pencil. This is the part that keeps them from coming back.
- 5
We install fresh Owens Corning insulation to the right R-value. San Antonio homes in Climate Zone 2 need R-30 to R-38 in the attic. We match the existing product where possible, or upgrade to ProPink blown-in if the old material was inadequate.
- 6
We walk you through the job and back it with the Done Right Promise. If anything isn’t right, we make it right. That’s lifetime workmanship, and it’s in writing.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in San Antonio
Here’s what San Antonio homeowners can expect to pay for common Owens Corning attic scenarios. Prices assume a typical 1,500 to 2,200 square foot single-story home.
- Attic cleanout with basic sanitizing: $800 to $1,600. This includes removing contaminated Owens Corning insulation, vacuuming the decking, and a basic enzyme treatment.
- Full attic cleanout with deep sanitizing and deodorizing: $1,400 to $2,600. This adds a full decking scrub, fogging treatment, and ductwork inspection.
- Rodent exclusion and proofing (sealing entry points): $600 to $1,800 depending on how many openings need sealing and how hard they are to reach.
- Complete restoration: cleanout, sanitizing, exclusion, and new Owens Corning insulation: $2,800 to $4,500. This is the full job most San Antonio homeowners need after a significant infestation.
What moves the price is attic size, how long the rodents have been up there, whether the ductwork needs attention, and how many entry points need sealing. We’ll give you an upfront price before we start, and we’ll honor it. Call (866) 751-4428 for a free estimate.

FAQs
Rodent damage is considered environmental and is not covered under Owens Corning’s standard warranty, so you’ll need to pay for cleaning and replacement out of pocket. The good news is that replacing damaged sections won’t void the warranty on the rest of your insulation, and we handle it as an independent service provider without involving the manufacturer directly.
If more than roughly 30% of your Owens Corning insulation is contaminated, replacing it is usually the better financial choice. Urine-soaked or feces-contaminated fiberglass can’t be effectively cleaned once it’s saturated, and the R-value is already compromised. Call (866) 751-4428 and we’ll help you decide after we see the attic.
Most San Antonio rodent exclusion jobs can be scheduled within a few days, and the sealing work takes one day for a typical single-family home. The cleaning and insulation replacement usually takes another day. We answer the phone live 24/7, so call us when you hear scratching in the wall and we’ll get you on the schedule.
Yes, we remove all contaminated Owens Corning insulation, whether it’s ProPink blown-in or kraft-faced batts, before installing anything new. Leaving contaminated material in place just gives new rodents a reason to move in and keeps the odor in your attic.
In most San Antonio homes, we can match Owens Corning ProPink blown-in fiberglass or R-19/R-30 batts without issue. If the product has been discontinued or your attic was done years ago with a different density, we’ll quote the closest current equivalent and explain the difference before we install it.
