CertainTeed Attic Cleaning & Rodent Proofing in Pomona: What to Know First
CertainTeed attic cleaning and rodent proofing in Pomona typically runs $750-$2,400 depending on attic size, contamination level, and whether we’re doing a full exclusion job. Most cleanouts with rodent proofing are completed in a single visit, with sanitizing and air sealing done the same day. As an independent CertainTeed service provider, Warmline Insulation Co. works on homes across Pomona every week, and we’ll give you a straight answer about what’s living up there and what it’ll take to make the attic clean and rodent-free.
This page is for Pomona homeowners who have CertainTeed insulation or CertainTeed building products in the attic and are dealing with rodent activity, years of accumulated droppings, or insulation that’s been shredded into nesting material. If that sounds familiar, call (626) 341-0830 and a live person answers, 24/7.
How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes solid insulation products, but no fiberglass batt or blown-in material is rodent-proof. Here’s what we actually see in Pomona attics, and what we do about it.
- CertainTeed InsulSafe blown-in fiberglass becomes a nest site. InsulSafe’s loose, fluffy texture is easy for rats and mice to burrow into. Rodents tunnel through it, compress it, and leave urine and droppings throughout. We vacuum out the contaminated material with commercial HEPA-filtered extraction equipment, then sanitize the attic deck and refill with fresh material if needed.
- CertainTeed R-30 and R-38 kraft-faced batts peel at the edges over time. The kraft paper facing separates from the fiberglass, especially in Pomona’s heat when attic temperatures hit 130°F or more. Peeled facing exposes more fiberglass surface and creates crevices where rodents hide. We remove compromised batts, check what’s underneath, and replace with properly fitted material.
- CertainTeed DryRight or MemBrain vapor barriers trap rodent odor. Smart vapor retarders like MemBrain do their job with moisture, but they also hold the ammonia smell from rodent urine much longer than un-faced insulation. After exclusion, we pull back affected barrier sections, deodorize the deck, and re-install or replace the barrier so the smell doesn’t come back.
- CertainTeed CertaSpray open-cell foam can hide entry points for years. Open-cell spray foam expands to fill cavities, but rodents will chew through it where it meets roof decking or wall top plates. The damage often goes unnoticed because the foam’s surface looks intact from the attic floor. We inspect foam perimeter lines carefully during every rodent proofing job and seal chew-throughs with exclusion-grade materials.
- CertainTeed ToughGard duct board gets chewed at corners. Ducts made from ToughGard have fiberglass-facing surfaces that rodents gnaw to get into the conditioned air path. We inspect all duct runs in the attic, patch and seal damage, and recommend duct replacement where chewing has compromised the air seal.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
Here’s how a typical CertainTeed attic job goes from first call to finished cleanup, led by Neil Ashford and his Pomona crews.
- 1
You call (626) 341-0830. A live person answers, 24/7. We ask about the attic, the age of the insulation, and what you’ve seen or heard. We schedule a walkthrough, usually within a day or two.
- 2
We inspect the attic and identify every entry point. Rodents in Pomona get in through roof vents, gable gaps, plumbing stacks, and where AC lines penetrate the roof. We map every opening before we touch anything.
- 3
We remove contaminated CertainTeed insulation. Using HEPA-filtered vacuum extraction, we remove droppings, nesting debris, and compromised insulation. We bag it all and haul it away same day.
- 4
We sanitize and deodorize the attic deck. We treat the surface with an enzyme-based sanitizer that breaks down urine and pheromone trails. If the rodent odor stays in place, new rodents will find the same entry points.
- 5
We seal entry points with exclusion-grade materials. Steel mesh, hardware cloth, and pest-block foam at every opening. We don’t use spray foam alone; it’s chewable and gives homeowners false confidence.
- 6
We install fresh insulation and restore the attic. Whether you need new CertainTeed InsulSafe blown-in, R-38 batts, or a spray foam upgrade, we match the right product to your Pomona home’s needs. Every job is backed by our 90-Day Done Right Promise.
What CertainTeed Attic Cleaning & Rodent Proofing Costs in Pomona
Pricing in Pomona depends on three things: attic square footage, how much insulation needs removal, and how many entry points need sealing.
- Basic attic cleanout (no major rodent damage): $750-$1,200 for a typical 1,200-1,500 sq ft Pomona attic, including removal of debris and light contamination.
- Full cleanout with HEPA extraction and sanitizing: $1,200-$1,800 when rodent droppings and urine are widespread and insulation must be removed.
- Complete rodent proofing and exclusion: $400-$900 depending on the number of entry points and roofline complexity. Older Pomona bungalows and ranch homes with multiple roof penetrations trend toward the higher end.
- New CertainTeed insulation after cleanout: $1,500-$3,500 depending on R-value and product type. Blown-in InsulSafe runs less than CertaSpray foam.
Every estimate is free and upfront. No surprises on the invoice. Call (626) 341-0830 and we’ll give you a number you can actually plan around.

FAQs
No, attic cleaning and rodent proofing done by a licensed contractor does not void CertainTeed’s product warranty on undamaged insulation. However, CertainTeed’s warranty does not cover rodent damage, so cleaning and exclusion are your responsibility as the homeowner. We document everything before and after so you have a clear record for any future warranty claims.
Most Pomona attic cleanouts are scheduled within 48-72 hours of your call, and most jobs are completed in a single visit. We carry extraction equipment and sanitizing supplies on every truck, so there’s no waiting on a second appointment.
If droppings and urine are concentrated in one small area, sanitizing and patching the insulation can work. If contamination is widespread, which is common in Pomona attics where rodents have been active for months, full removal and replacement is the safer, more cost-effective choice. We’ll tell you honestly which applies to your attic. Neil’s been known to tell homeowners a job isn’t worth doing, and he’ll do the same for you.
