This page is for homeowners who invested in Owens Corning insulation and now need the attic cleaned, sanitized, and sealed against rodents without compromising that insulation’s performance. Rodents in a Santa Monica attic don’t just make noise; they shred insulation, compress its R-value, and leave behind waste that can affect indoor air quality. Walt’s Insulation has been handling these exact situations since 2000 as an independent Owens Corning service provider, not a manufacturer affiliate. Walt Brenner grew up learning the trade at St. Philip’s College before heading west, and he’s been working Santa Monica attics since the early 2000s, from older bungalows near Montana Avenue to newer builds closer to the water. We know how marine air off the Pacific compounds rodent damage, and we fix it right the first time.
How Owens Corning Products Fail - and How We Fix Them
Owens Corning insulation does its job well, but no insulation brand is immune to what rodents do inside a Santa Monica attic. Here’s what we see most often.
- Compressed fiberglass batts lose their R-value. Owens Corning EcoTouch batts are designed to maintain loft, but rats and mice burrow through them and pack them down. Once compressed, the trapped air pockets that provide insulation are gone. We remove the ruined material, and if the rest of the attic is salvageable, we re-fluff and reinstall; otherwise we replace with new Owens Corning batts matched to the existing R-value. The fix only sticks if we seal the entry points, which is step one either way.
- AttiCat blown-in fiberglass gets tunneled and scattered. Homes with Owens Corning AttiCat loose-fill often have rodent nests hidden under the surface. Rodents tunnel through blown fiberglass, creating bare spots and matted clumps. We vacuum out the contaminated material, sanitize the attic deck, and blow in fresh AttiCat to the proper depth for Santa Monica’s climate zone, which is R-30 to R-38 minimum in most cases.
- ProPink batt facings trap moisture and waste. The kraft paper facing on some Owens Corning batts can absorb rodent urine and hold it against the drywall below, leading to ceiling stains and odor that no amount of air freshener will fix. This is one of the most common calls we get from Santa Monica homeowners who notice a smell but can’t locate the source. We remove the spotted material entirely; spot cleaning doesn’t address what’s soaked through the facing.
- Rodents nest inside existing Owens Corning duct wrap. If your ducts are wrapped with Owens Corning fiberglass duct insulation, rodents will tear gaps in it to build nests. The result is unconditioned air leaking into the attic, which drives your energy bills up. We repair or replace the damaged wrap after the exclusion work is done, using the same brand or equivalent depending on what’s available locally.
- Foam board and foam sealants get chewed through faster than you’d expect. Even Owens Corning FOAMULAR or EnergyComplete spray foam can be gnawed through by determined rodents, especially roof rats, which are common in Santa Monica’s coastal neighborhoods. Once they breach a foam air seal, the whole assembly’s performance degrades. We inspect all foam sealing points during exclusion and reinforce with steel wool, hardware cloth, and sealant that rodents can’t chew through as easily.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
We’ve done enough of these jobs in Santa Monica to have a routine that works without cutting corners. Here’s how a typical call goes.
- 1
Attic inspection and entry point mapping. We go up, document the damage, photograph what we find, and identify every gap, vent, and penetration rodents are using to get in. Santa Monica homes built before the 1990s often have multiple entry points because the original vent screens and soffit intersections deteriorate in salt air.
- 2
Removal of contaminated insulation. We vacuum out any Owens Corning material that has been soiled, tunneled, compressed, or nested in. Contaminated material doesn’t get reused. We bag it and remove it from the property the same day.
- 3
Sanitizing and decontamination. We treat the attic deck and any remaining insulation contact surfaces with an enzyme-based sanitizer that breaks down urine, feces, and odor. If the drywall below has absorbed moisture from rodent activity, we check for concealed stains and recommend a plan before resealing.
- 4
Exclusion and rodent proofing. We seal entry points with galvanized hardware cloth, metal flashing, and sealant rated for outdoor exposure. This is the step most contractors skip, and it’s the reason the problem comes back. Exclusion also covers all pipe penetrations, vent screens, and the gaps around your Owens Corning insulation baffles, which rodents love to push aside.
- 5
Insulation replacement and finishing. We install fresh Owens Corning batts or blown-in AttiCat to match or exceed the original R-value, restore the air seal with caulk, spray foam, and weather stripping where needed, and verify the ventilation path from soffit to ridge is clear. If you need new vent screens, we’ll quote them separately.
- 6
Final walkthrough and the Done Right Promise. Before we leave, we walk you through what we did and why. Every job is covered by our lifetime workmanship guarantee. If something wasn’t done right, we make it right, no runaround. That’s the Done Right Promise, and it applies to every Owens Corning job we complete.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Santa Monica
| Job Scope | Typical Range | What’s Included |
|---|---|---|
| Spot clean and exclusion | $450 – $900 | Removal of one small contaminated area, sanitizing, sealing of 1-3 entry points |
| Full cleanout, sanitize, and basic exclusion | $1,200 – $2,200 | Vacuum removal of soiled insulation, enzyme sanitizing, sealing of standard entry points, disposal |
| Full cleanout plus insulation replacement | $2,500 – $3,800 | Removal and disposal, full sanitizing, new Owens Corning batts or AttiCat blown-in, exclusion sealing |
| Duct wrap repair/replacement | $600 – $1,800 | Damage assessment, removal of torn Owens Corning wrap, new wrap installed on accessible duct runs |
What moves the price is attic size, how much insulation is contaminated, how many entry points need sealing, and whether the rodent activity has reached the ductwork or ceiling drywall. Attics in older Santa Monica neighborhoods like Sunset Park and Ocean Park tend to have more entry points and tighter access, which adds labor. We charge upfront pricing, so the quote we give you is the price you’ll see on the invoice. There’s no trip charge inside our service county, and if you have another written estimate, bring it in and we’ll give you a free second opinion. Call (424) 396-5828 and we’ll come take a look.

Everything else is just a second invoice.” We also offer $40 off any repair over $200 and a permanent 10% discount for seniors and veterans, always.
FAQs
No, not with our method. Owens Corning warranties cover manufacturer defects in the insulation itself, not damage from rodents or the cleaning and replacement process. We match new insulation to your existing product, install it to manufacturer specs, and document the work. The Done Right Promise applies regardless of what the manufacturer warranty does or doesn’t cover.
Sometimes, yes. If the batts are dry, uncompressed, and haven’t been nested in, we can remove surface debris, sanitize, and reinstall. But once urine has soaked through the facing or rodents have tunneled through blown-in fiberglass, the material is compromised and cleaning it won’t restore the R-value or the air quality. We’ll tell you straight which situation you have before any work starts.
Most calls get scheduled within one to three business days, and if you have a live rodent issue we can often get a technician out the same day for an inspection and initial sealing. A full cleanout and replacement typically takes one to two days depending on attic size. Call (424) 396-5828 and we’ll give you an honest timeline.
When we’re replacing insulation, we prefer to match what’s already there. If your attic had Owens Corning EcoTouch batts, that’s what we’ll reinstall unless you ask for an upgrade to Rockwool or another brand. You get a clear choice and a fair price either way, and we don’t mark up material beyond what’s reasonable for a local independent shop.
For small damaged areas, spot repair is cheaper up front and works fine if the rest of the attic is clean. For extensive contamination or a long-running rodent problem, full removal and replacement is usually cheaper in the long run because you’re not paying to re-clean the same attic every year. We’ll show you the numbers both ways and you decide; estimates are free.
