CertainTeed Attic Cleaning & Rodent Proofing in San Antonio: What to Know First
As an independent CertainTeed service provider, we clean, sanitize, and rodent-proof attics in San Antonio that are insulated or finished with CertainTeed products, and most jobs are completed in one to two days depending on the size of the attic and the extent of the rodent damage. Rodent contamination in a CertainTeed-insulated attic is not a wait-and-see situation, because rats and mice tunnel through batts, shred facing material, and leave waste that compromises both air quality and the insulation’s thermal performance. Pricing is job-specific, not a one-size-fits-all number, and we give you an exact figure before any work starts. If you have rodent activity in a CertainTeed attic anywhere in San Antonio, call (866) 751-4428 and a live person will answer.
This page is for San Antonio homeowners who already own a CertainTeed product, whether it’s insulation, ductwork, or a vapor barrier, and need attic cleaning and rodent proofing done right the first time. If you’re smelling something in the attic or hearing scratching at 3 a.m., you’ll find straight answers here.

How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes good materials. The problem in San Antonio attics is rarely the product itself. It’s what rats, mice, and our climate do to it. Here are the five failure modes we see most often on CertainTeed jobs in this part of Texas.
- Rodent tunneling through CertainTeed InsulSafe or TrueComfort blown-in fiberglass. Rats love loose-fill fiberglass because it holds heat and makes easy burrows. They tunnel through it, packing it down and leaving urine trails that collapse the loft. We remove the contaminated material, sanitize the deck, and either replace it with fresh CertainTeed blown-in product or, if the homeowner prefers, another brand we install like Owens Corning or Johns Manville. The fix starts with a full cleanout. No shortcuts here.
- Mice shredding the kraft facing on CertainTeed R-13 or R-19 fiberglass batts. Faced batts are the easiest target in an attic. Mice tear the paper facing for nesting material, which leaves the fiberglass exposed and the vapor retarder useless. Once the facing is shredded, the batt loses some of its structural integrity. We remove affected batts, sanitize around the area, and reinstall clean, unfaced batts or blown-in fill to match the existing R-value.
- Nesting inside CertainTeed ductwork (TrueComfort or CertaFlex). If rodents get into flexible ductwork, you’ll hear it in the house. They chew through the outer jacket and nest right in the insulation layer. The sniff test usually confirms it. We inspect every duct run, remove contaminated sections, and replace with new CertaFlex duct of the same diameter. This is a common one in older San Antonio homes where ducts were installed 15 or 20 years ago and have sagged toward the attic floor.
- Urine-soaked CertainTeed vapor barrier or housewrap used in attic knee walls. Some San Antonio homes have CertainTeed MemBrain or similar vapor barrier material on knee walls or attic access panels. Rodents urinate on these surfaces and the smell soaks in. You can’t scrub it out. We cut out the affected sections, sanitize the framing underneath, and patch with new material before re-insulating.
- Compression and displacement of CertainTeed Sustainable Insulation or Optima blown-in fiberglass after rodent activity plus San Antonio heat. Here’s a South Texas reality a manufacturer’s site won’t tell you: a CertainTeed attic in San Antonio can hit 140°F in July. When rodents have packed down sections of blown-in fill for nesting, those compressed areas lose R-value fast, and the heat accelerates moisture issues from rodent waste. On a 100-degree day, a urine-soaked pocket of insulation in a 140-degree attic is basically baking into the decking. We’ve pulled out material that was fused to the wood. The fix is a full cleanout, sanitizing, and fresh fill at the right depth for our climate zone.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
Every job follows the same steps. No surprises, no upsells. Here’s what happens when you call us about a CertainTeed attic in San Antonio.
- 1
You call and talk to a person. We answer the phone live around the clock. You describe what you’re hearing, smelling, or seeing. If it sounds like rodents, we schedule a visit. No trip charge inside our service county.
- 2
We inspect the entire attic. Our technician checks every corner, including under insulation, around duct runs, at soffit vents, and along the roofline. We identify entry points, nesting areas, and which CertainTeed products have been damaged.
- 3
We give you a written, line-by-line price. You see exactly what the cleanout costs, what the sanitizing costs, and what the proofing costs. No vague “attic service” line. If you have a written estimate from another company, bring it and we’ll give you a free second opinion on it.

We do the work. Contaminated insulation comes out. The attic gets vacuumed, sanitized with a hospital-grade disinfectant, and treated for odor. Damaged CertainTeed batts or duct sections get replaced. Entry points get sealed with steel mesh and foam as needed, including gaps at roof intersections, plumbing vents, and gable vents.
- 5
We run a final check. We walk the attic with you if you’re comfortable doing that, or we photograph everything and explain what you’re looking at. The goal is that nothing surprises you.

The Done Right Promise kicks in. If something isn’t done right, we come back and make it right. Lifetime workmanship. It’s not a slogan. It’s how Walt has run this business since 2000.
What CertainTeed Attic Cleaning & Rodent Proofing Costs in San Antonio
Attic cleaning and rodent proofing in San Antonio runs a wide range because every attic is different. The size of the attic, how much insulation is contaminated, how many entry points need sealing, and whether ductwork is involved all move the number. Here are honest ranges for the most common CertainTeed scenarios we handle.
- Basic attic cleanout and sanitizing (no insulation replacement): $800 to $1,600 for a typical 1,200 to 1,800 square foot San Antonio home.
- Cleanout, sanitizing, and rodent proofing with entry point sealing: $1,400 to $2,800 depending on the number of entry points and accessibility.
- Cleanout plus removal and replacement of contaminated CertainTeed blown-in insulation: $2,500 to $5,000 for a single-story home with R-30 to R-38 depth.
- Full restoration including duct replacement, insulation replacement, sanitizing, and proofing: $5,000 to $9,000 on larger homes or severe infestations.

FAQs
Yes, in most cases. CertainTeed’s product warranties cover manufacturing defects, not damage from rodents, moisture intrusion, or improper installation conditions. Rodent activity is considered environmental damage, and no insulation manufacturer covers it. That’s why cleaning and proofing early matters more than arguing with a warranty department. Call us and we’ll assess the damage before it spreads.
No, and here’s why. Once rodents have tunneled through and urinated in loose-fill fiberglass, the contamination runs deeper than the visible surface. You can vacuum the top layer, but the waste has soaked down into the material below. Partial removal leaves contaminated insulation in place, and the smell comes back within weeks when the attic heats up. We remove the affected zones completely, sanitize the deck, and refill to the correct R-value for San Antonio’s climate.
We can usually be out within 24 to 48 hours, and we do our best to accommodate emergency situations where rodents have chewed into living spaces or the smell is coming through the ceiling. Call (866) 751-4428 and tell us what’s happening. We’ll get you on the schedule and give you a straight answer about timing.
Always proof first. If you clean and sanitize the attic but leave entry points open, new rodents will re-infest the space within weeks and you’ll pay for the cleanout twice. Our process seals entry points before or during the sanitizing step, not after. The order matters, and it saves you money in the long run.
We can, and in many cases we do. We have access to CertainTeed InsulSafe, TrueComfort, Optima, and CertaFlex products through our supplier network. But we’ll also tell you when a different brand would serve you better for the same or lower cost. We install Owens Corning, Johns Manville, and Rockwool regularly, and we’re happy to explain the trade-offs. The decision is yours. We just give you honest information to make it with.
If you’ve got rodents in your CertainTeed attic in San Antonio, don’t wait until the smell gets worse or the wiring gets chewed. Call (866) 751-4428 for a free estimate. We’ll answer the phone, schedule the visit, and give you a real number before any work begins.
