CertainTeed Attic Cleaning & Rodent Proofing in Santa Monica: What to Know First
CertainTeed attic cleaning and rodent proofing in Santa Monica typically runs $1,200 to $4,800 depending on attic size, contamination level, and whether we’re doing full exclusion or spot sealing. Most jobs are completed in one to two days, and we schedule within the same week for emergencies where rodents are actively chewing through CertainTeed insulation. We’re an independent CertainTeed service provider, which means we work on your home’s existing CertainTeed products without being beholden to any manufacturer’s script.
If you own a Santa Monica home with CertainTeed insulation in the attic and you’ve heard scratching, found droppings, or noticed your heating bill climbing, this page is for you. Call (424) 396-5828 and a live person answers. Always.
How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes solid insulation products. They also make products rodents love to destroy. Here’s what we actually see in Santa Monica attics, and what we do about it.
- InsulSafe XC blown-in fiberglass gets tunneled and compacted. Rodents burrow through the loose fill, creating pathways that collapse the insulation’s loft. R-value drops fast when fiberglass gets matted down. We see this constantly in homes near Palisades Park where tree squirrels jump from overhanging branches. Our fix: full removal of contaminated fill, sanitizing, then air sealing before new insulation goes in.
- Optima blow-in fiberglass hides urine trails you can’t see until you disturb it. Rats run along joists and soak the surrounding material. The smell hits when you fluff it during an energy audit. We remove the affected sections, not just spot-treat, because ammonia from rodent urine breaks down fiberglass binders over time.
- TrueComfort blown-in fiberglass in Santa Monica’s marine air picks up moisture that makes nesting material clump. Fog and salt air off the Pacific get into attics through soffit gaps. When rodents build nests in TrueComfort, the moisture in their urine combines with coastal humidity, and the material mats into hard clumps that don’t insulate. We address the ventilation issue and replace the affected fill.
- CertainTeed batt insulation around plumbing penetrations gets chewed into confetti. Rats need to wear down their teeth constantly. The kraft paper facing on CertainTeed batts tears easily, and the fiberglass becomes nesting material. We see this in older bungalows near Montana Avenue where original plumbing stacks run through the attic. We seal the penetrations with steel wool and foam before replacing batts.
- Vapor barriers on CertainTeed batts trap rodent scent markers that attract new infestations. Even after you remove the rodents, the scent stays in the kraft facing. We’ve gone into attics that were “cleaned” by other companies, only to find the same smell because they left the old facing in place. We strip it all out and start fresh, because rats follow old scent trails like a road map.
One detail you won’t find on CertainTeed’s site: rodent damage almost never voids the product warranty on materials, but the labor to clean and restore is entirely on the homeowner. That’s why fast action matters more than which CertainTeed product you have up there.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
We’ve done hundreds of these jobs across Santa Monica, from the flats to the canyon edges. Here’s how a typical CertainTeed attic restoration goes, start to finish.
- 1
Call and walkthrough. You call (424) 396-5828. We schedule a visit. Walt or one of our lead techs walks the attic, checks insulation depth, identifies entry points, and gives you a written estimate. No trip charge inside our service county.
- 2
Contamination assessment. We determine how much CertainTeed material needs removal versus what can be saved. This depends on rodent traffic volume, not just visible droppings.
- 3
Removal and extraction. We vacuum out contaminated CertainTeed insulation using commercial HEPA-filtered equipment. We bag and remove everything, including old nesting material and carcasses if present.
- 4
Sanitizing and deodorizing. We treat the attic deck, joists, and any remaining structure with an enzyme-based cleaner that breaks down urine and scent markers. This step is non-negotiable; skip it and new rodents find their way back.
- 5
Rodent proofing and exclusion. We seal entry points with steel mesh, galvanized flashing, and pest-grade foam. Gable vents get screened. Soffit gaps get closed. Every gap bigger than a dime gets addressed, because a young rat needs less than half an inch.
- 6
Insulation replacement and final check. We install new insulation, whether that’s back to CertainTeed or a better fit for your home. We test airflow, confirm no remaining gaps, and walk you through what we did. The Done Right Promise covers our workmanship for life, so if something’s not right, we make it right.
We don’t rush step three or step five. Those are the ones that determine whether you’re calling us again in six months.
What CertainTeed Attic Cleaning & Rodent Proofing Costs in Santa Monica

What moves the price? Attic accessibility, how much insulation needs removal, how many entry points we’re sealing, and whether you have old knob-and-tube wiring that requires extra care.

Why Santa Monica Homeowners Call Walt’s Insulation for CertainTeed Work
We’ve been doing this since 2000, and we’re the one down the road, not an 800 number. Walt Brenner started this company because he got tired of watching Sacramento and Orange County crews roll into Santa Monica, underbid local shops, and disappear when the work failed. That doesn’t happen here. We have a published address. We have a license number you can look up. And when you call at 2 a.m. because you hear something in the attic, a live person answers.
Our techs are background-checked and uniformed. They know CertainTeed products because they’ve torn out enough of them to know exactly how they fail in coastal air. We also work with Owens Corning, Rockwool, Johns Manville, Knauf, and Reflectix, so if your attic needs a different product than what’s currently up there, we’ll tell you straight. The Done Right Promise backs every job for life. Do it right once. Everything else is just a second invoice.
We also stand by the standing offers: $40 off any repair over $200, free second opinions on written estimates, no trip charge inside our service county, and a permanent 10% discount for seniors and veterans.
FAQs
Rodent damage does not void the CertainTeed material warranty, but the warranty covers manufacturing defects, not animal contamination or the labor to remove and replace the damaged insulation. That cleanup cost is on you, which is why fast exclusion work saves real money. Call (424) 396-5828 and we’ll walk you through what your specific situation will cost.
Yes, in about half of cases we can remove only the contaminated sections and leave clean CertainTeed insulation in place. If the infestation was localized near one entry point, spot removal works. If rodents tunneled across the entire attic, full removal makes more sense than trying to salvage matted fill. We’ll show you photos from your attic so you can make the call with your own eyes.
We schedule active infestations within the same week, and often within 48 hours when we have a crew available. Rodents chewing through CertainTeed insulation and wiring is a fire hazard, so we treat these calls as urgent. Call (424) 396-5828 and tell the person who answers you’ve got active rodents; that’s a real human, not a recording.
Cleaning and proofing now is cheaper, full stop. A $2,500 cleanout and exclusion job today beats a $12,000 rewire and full attic restoration after rats chew through Romex and soak your CertainTeed insulation for another year. We’ve seen both, and the second one is the one homeowners lose sleep over.
We install whichever product fits your attic best. Sometimes that’s CertainTeed InsulSafe XC. Sometimes Rockwool or Owens Corning makes more sense for your ventilation setup and budget. We carry and install all of them, so you get an honest recommendation, not a sales pitch for one manufacturer. That’s the difference between a contractor who works for a brand and one who works for you.
