Icynene Attic Cleaning & Rodent Proofing in Pasadena: What to Know First
Icynene attic cleaning and rodent proofing in Pasadena typically runs $1,200 to $3,800 depending on attic size, how long rodents have been active, and whether the existing Icynene foam needs repair or full sections removed and replaced. Most jobs are done in one to two days, and we work as an independent Icynene service provider, which means we fix what’s there without pushing a full replacement you may not need.
This page is for Pasadena homeowners who have Icynene spray foam insulation in their attic and have either found rodent activity, noticed odors, or suspect the foam has been compromised. You already paid for good insulation. The question now is whether it can be saved, and what it costs to make your attic clean, sealed, and rodent-free again. Call (626) 606-2964 and you’ll get Walt or one of our techs, not a call center.
Key takeaways:
- We clean, sanitize, and rodent-proof attics with existing Icynene foam, and repair or replace damaged sections as needed.
- Rodents chew through Icynene open-cell foam faster than you’d think, and the damage is often hidden behind the surface.
- We’re an independent shop, not an Icynene dealer, so we recommend what’s right for your house, not what moves inventory.
- Live person answers 24/7. Same-week appointments available in most Pasadena neighborhoods.
How Icynene Products Fail, and How We Fix Them
Icynene makes a good product. But in Pasadena attics, with our heat, our rats, and our older housing stock, we see the same failure patterns repeat themselves. Here’s what actually goes wrong, and what we do about it.
- Icynene Classic (open-cell) rodent tunneling. Rats and mice burrow straight into open-cell foam. It’s soft, it’s warm, and it makes a perfect nesting material. The damage often looks minor from the surface, but underneath you’ll find tunnels running feet into the foam. We cut out every affected section back to clean foam, remove contaminated material, then reinforce the area before any re-insulation. Patching over tunnels doesn’t work. The rodents just come back to the same spot.
- Icynene ProSeal (closed-cell) urine saturation at the sheathing line. Closed-cell foam resists moisture, but rodent urine pools on top and works into the seam where foam meets roof decking. The smell lingers because the urine has nowhere to drain. We remove the affected foam, treat the decking with an enzyme decontaminant, and install new ProSeal or equivalent closed-cell in its place. Skipping the enzyme step means the attic still smells on hot Pasadena afternoons.
- Icynene Classic delamination from gable-end heat cycling. Pasadena attics regularly hit 130°F in August. Over years, the heat cycling causes open-cell Icynene to pull away from roof sheathing, especially on west-facing gable ends. That gap is where rodents travel unnoticed and where your A/C leaks conditioned air. We re-adhere where possible or replace the delaminated section, then air-seal the framing joints before refinishing.
- Droppings and dander embedded in Icynene’s rough surface. Open-cell foam has a nubby, irregular texture that traps droppings, dander, and dust. A surface vacuum doesn’t get it out, and disturbing the foam too aggressively tears it. We use soft-bristle HEPA extraction followed by an enzyme mist, and we’re careful not to compromise the foam’s integrity. If the contamination is deep, we cut and replace. No amount of cleaning makes deeply soiled foam sanitary again.
- Rodent entry points hidden behind Icynene at the soffit line. The number one reason rodent problems come back after a cleaning job is that the entry points were never found. Icynene installed into the soffit area can hide gaps where the roof line meets the fascia. We pull back the foam at every suspect penetration, seal the gap with steel mesh and sealant, then respray. If the entry isn’t sealed, the cleaning doesn’t matter.
Our Icynene Attic Cleaning & Rodent Proofing Process
Every Icynene job follows the same sequence, whether it’s a century bungalow near the Rose Bowl or a newer build in Hastings Ranch. Here’s how it goes.
- 1
Call and a real conversation. You tell us what you’re seeing, smelling, or hearing. We ask about your Icynene type if you know it, the attic layout, and how long the problem’s been going on. You can send photos or we can just come look.
- 2
Attic inspection. Uniformed, background-checked techs go up and map everything: foam condition, rodent activity, entry points, ventilation, and contamination level. We take photos so you see what we see. No scare tactics, just facts.
- 3
Written plan and price. You get a line-item proposal covering what gets removed, what gets cleaned, what gets sealed, and what gets replaced, if anything. We use OEM Icynene product when the existing foam has remaining manufacturer warranty that matters, and quality-compatible material when it doesn’t. We explain which is which.
- 4
The work. We contain the work area, remove contaminated foam, vacuum and extract debris with HEPA equipment, apply enzyme treatment to decking and framing, seal entry points with exclusion-grade materials, and re-insulate any removed areas.
- 5
Post-job walkthrough. We show you the before-and-after photos, point out every seal we made, and explain what to watch for. If a rodent shows up in a spot we sealed, we come back under the Done Right Promise and find what we missed. No runaround.
- 6
Follow-up. We check in after a couple weeks to make sure things are quiet. If they aren’t, we’re back out.

What moves the price: attic square footage, how deeply the rodents got into the foam, whether the Icynene is open-cell or closed-cell, how accessible your attic is, and how many entry points need sealing. We offer no trip charge inside our service county, and you’ll get a free written estimate before any work starts. The price we quote is the price you pay.

Why Pasadena Homeowners Call Walt’s Insulation for Icynene Work
Walt Brenner started this company in 2000, and we’ve been up and down every canyon and boulevard in Pasadena since. We’re the one down the road, not a franchise with an 800 number and a rotating cast of subcontractors. When you call, a live person picks up, 24/7, because your house doesn’t keep business hours and neither do we.
We know Icynene because we’ve worked with it for over two decades, alongside Owens Corning, Rockwool, Johns Manville, CertainTeed, Demilec, Knauf, and GreenFiber. If your attic has a Reflectix radiant barrier mixed in with the Icynene, we handle that too. Every job is covered by the Done Right Promise: if it’s not done right, we make it right. For life. Plus a permanent 10% discount for seniors and veterans, and $40 off any repair over $200. That’s the whole deal, no fine print.
Frequently Asked Questions
No. Icynene’s limited warranty covers manufacturing defects and, on some installer-applied warranties, thermal performance. It does not cover rodent damage, pest intrusion, or contamination. Rodent damage is considered an environmental issue, not a product defect. Before we do any work, we’ll help you check whether your remaining warranty has any value, and we’ll tell you straight if it doesn’t.
Sometimes, yes. Surface dust and light debris can be carefully extracted without removing the foam. But if rodents have tunneled through it or saturated it with urine, cleaning won’t do the job. We’ll show you photos and tell you honestly which situation you have. If it can be cleaned, we clean it. If it can’t, we replace only what’s necessary.
Most calls get a same-week visit, and we keep slots open for emergencies where there’s active rodent activity or water intrusion into the foam. Call (626) 606-2964 and you’ll speak to a person who can tell you the next available time, not a recording.
Sometimes it is, especially if the rodent damage is extensive and the foam is badly compromised. But Icynene’s air-sealing performance is hard to match with batts alone, so we only recommend switching when the numbers and the attic condition actually support it. We do plenty of both, so there’s no upsell pressure either way.
Yes. The Done Right Promise covers our workmanship for life. If rodents get back in through an entry point we sealed and shouldn’t have missed, we return and fix it at no charge. We can’t stop new rodents from trying to get in, but we can make sure they don’t succeed through the places we worked on.
