Icynene Attic Cleaning & Rodent Proofing in Anaheim: What to Know First
Icynene attic cleaning and rodent proofing in Anaheim typically runs between $1,200 and $4,800 depending on attic size, contamination level, and whether you own a Classic, ProSeal, or newer open-cell line. Most jobs are completed in one to two days, including removal of soiled insulation, decontamination, air sealing, and exclusion work. We’re an independent Icynene service provider, not a manufacturer affiliate, which means we fix what’s actually wrong without pushing a full replacement unless you need one.
This page is for Anaheim homeowners who bought Icynene spray foam thinking it was permanent, then discovered rodents can still tunnel through it, nest in it, and turn it into a health hazard. If that’s you, call (657) 214-8224 and you’ll get a live person, not a voicemail. Walt Brenner or one of our techs will walk you through what we’re seeing in your neighborhood and what it’ll take to fix it.
- Key takeaway: Icynene foam doesn’t repel rodents. It gives them a warm, chewable burrow. Cleaning and proofing is a real fix, not a patch job.
- Key takeaway: We’ve been doing attic work in Anaheim since 2000. We’ve seen every foam failure mode this city’s heat and rat population can produce.
- Key takeaway: Every job is covered by the Done Right Promise. If it’s not done right, we make it right. No runaround.
How Icynene Products Fail - and How We Fix Them
Icynene makes good foam. It’s not magic. In Anaheim’s attic heat and with the roof rat and Norway rat pressure we get from mature landscaping and older construction, even the best spray foam breaks down or gets invaded. Here’s what we actually see on Icynene jobs across Anaheim, from the Platinum Triangle condos to the ranch houses in West Anaheim.
- Icynene Classic (open-cell) rodent tunneling. Classic is soft and spongy, which makes it easy for rats to burrow through. We regularly open up Classic attics in Anaheim and find tunnel networks running from the eaves to the HVAC chase. The fix isn’t just bait. We remove the compromised sections, sanitize, and install exclusion at every entry point before re-insulating.
- Icynene ProSeal delamination from trapped moisture. ProSeal is a closed-cell product that’s great at air sealing, but if rats chew through the vapor barrier or your attic ventilation is undersized for Anaheim’s summer humidity, moisture gets trapped between the foam and the roof deck. You smell it before you see it. We cut out the delaminated sections, address the airflow problem, and reapply.
- Rodent urine saturation in open-cell Icynene. Open-cell foam acts like a sponge. Once rats nest in it, urine soaks deep into the cells. You cannot clean this. You have to remove the affected foam, sanitize the framing, and start fresh. We see this most often in older Anaheim homes with original shake roofs that have small gaps at the eaves.
- Boric acid and pest-controller overspray damage. Some pest companies treat attics without considering the foam. Their chemicals can degrade Icynene’s fire retardant and cause premature crumbling. We’ve cleaned up after enough of these jobs in Anaheim to recognize the pattern immediately. Our decontamination process removes residue before we touch the insulation.
- Icynene Classic shrinkage around recessed lights and vent penetrations. In Anaheim attics that hit 140°F plus in August, open-cell Icynene can shrink back from penetrations over a decade or two. That creates air leaks and rodent highways. We re-foam these gaps with compatible material and seal the openings properly.
Our Icynene Attic Cleaning & Rodent Proofing Process
- 1
Inspection and honest assessment. We get in the attic, photograph everything, and tell you what’s actually happening. You’ll see the damage yourself. No mystery.
- 2
Entry point mapping. We trace every gap, crack, and eave opening rats are using. In Anaheim, that usually includes plumbing vents, AC line sets, and old shake roof transitions.
- 3
Contaminated foam removal. We cut out the Icynene sections that are soaked, tunneled, or crumbling. We bag and remove everything, not just the visible surface.
- 4
Sanitizing and decontamination. We treat the framing and sheathing with an antimicrobial cleaner that kills the bacteria and neutralizes odor. This step matters. Skip it and the smell comes back.
- 5
Exclusion and proofing. We seal every entry point with steel mesh, hardware cloth, and foam-compatible sealants. We use materials that hold up in Anaheim heat, not caulk that cracks in two summers.
- 6
Re-insulation and final test. We reapply Icynene or another appropriate insulation, then do a final inspection to confirm nothing’s getting back in. Every job is covered by the Done Right Promise.

Why Anaheim Homeowners Call Walt’s Insulation for Icynene Work
We’ve been the one down the road since 2000. Walt Brenner started this company with a simple idea: do the job right the first time, because we’re the ones who have to stand behind it. That’s not a slogan. It’s how we’ve stayed busy in Anaheim for over 25 years while national chains cycle through crews and contractors ghost their customers.
Our techs are background-checked and uniformed. They know Icynene’s product lines because they’ve cut into them, removed them, and reinstalled them for years. And when a job calls for something other than Icynene, we work with Owens Corning, Rockwool, Johns Manville, Knauf, CertainTeed, Demilec, and GreenFiber. For radiant barrier work, we also handle Reflectix. We’re not married to one brand. We’re married to doing it right.
Every call is answered by a live person, 24/7. That includes weekends, holidays, and 2 a.m. when you hear scratching in the ceiling and can’t sleep. Call (657) 214-8224. You’ll talk to a real person who actually knows attic work.
FAQs
It can, if the work is done incorrectly. That’s why we follow warranty-safe removal practices and document everything with photos. As an independent Icynene service provider, we can’t speak for the manufacturer, but we can tell you that leaving rodent-contaminated foam in place is worse for your home than any warranty concern.
Surface cleaning works for dust and light debris, and we can do that. But if rats have tunneled through the foam or urinated in it, no cleaning product on the market will fully penetrate open-cell Icynene. That foam has to come out. Anyone who tells you otherwise is selling you a temporary smell fix.
In most cases, we can inspect within 24 to 48 hours. Emergency rodent situations are different. We’ve had Anaheim homeowners hear rats in the attic on a Sunday and have us out Monday morning. Call (657) 214-8224 and we’ll tell you exactly when we can be there.
It depends on how much foam is compromised. If 20% or less is damaged, we can remove just those sections and re-foam the gaps. That’s usually the most cost-effective route. If rats have tunneled through more than half the attic, full removal and re-insulation often costs less than patching forever. We’ll show you the numbers both ways and let you decide.
Yes. Part of our cleanout and decontamination process is removing any carcasses, droppings, and nesting material. We don’t leave the nasty stuff for you to deal with. When we’re done, the attic is clean, sanitized, and sealed.
Sometimes, especially if the damage is recent and you have documentation. We provide detailed photos and a written report that many Anaheim homeowners use to file claims. Call (657) 214-8224 and we can talk through what your policy might cover. Estimates are free.
