This page is for Fullerton homeowners who had Icynene spray foam installed and now have rodent damage, old droppings, or just want the space cleaned out properly. We’ve been doing this since 2000, and we’ve cleaned out more Icynene attics in Fullerton than we can count, from houses near Hillcrest Park to the tract homes off Bastanchury Road.

Key Takeaways

• Icynene open-cell foam absorbs rodent urine and holds odor, which is why a simple vacuum-out rarely solves the smell problem.
• Rodents tunnel through open-cell Icynene in a way they don’t through closed-cell foam or fiberglass.
• Repairing an Icynene attic after rodent damage usually means cutting out contaminated sections, sanitizing, and re-foaming or patching.
• We offer a free second opinion on any written estimate, no trip charge inside our service county, and a permanent 10% discount for seniors and veterans.

How Icynene Products Fail - and How We Fix Them

Spray foam is a great product, but Icynene’s open-cell lines have some specific weaknesses in Fullerton attics. Here’s what we actually see when we open an access hatch.

• Icynene Classic open-cell foam absorbs rodent urine like a sponge. Once rats or mice nest in it, the foam holds moisture from urine and droppings. That means the smell doesn’t go away with a surface cleaning. We cut out the contaminated sections, bag them, and sanitize the remaining material before patching. In Fullerton’s warm summers, that absorbed waste bakes and intensifies, so this is a job you don’t want to put off.
• Icynene ProSeal and Classic both get tunneled through by roof rats. Roof rats, the species we mostly deal with in Fullerton, chew nesting cavities right through open-cell foam. They don’t just skim the surface. We’ve pulled rats out of Icynene nests that were three feet deep in the foam near the eaves. The fix is removal of the tunneled foam, full exclusion sealing at every entry point, and replacement with new Icynene foam or a closed-cell alternative where the homeowner prefers it.
• Open-cell Icynene hides rodent damage from view. This is the one most owners don’t know. Rodents burrow inside the foam where you can’t see the damage from the attic hatch. You’ll smell it or hear it long before you spot it. We use a camera probe to check the interior of the foam field during inspection, not just the surface. Most companies don’t do that.
• Icynene foam delaminates from the roof deck after rodent traffic. The constant in-and-out of rodents breaks the foam’s bond to the sheathing, and once the foam pulls away, condensation can form between the foam and the wood in Fullerton’s cool, damp winter mornings. That leads to mold. Removing delaminated sections and re-foaming is a standard part of almost every rodent-damaged Icynene job we do.
• Evidence of rodent activity can void Icynene’s manufacturer warranty. Most spray foam warranties don’t cover damage from pests. Homeowners who call us before tackling the rodent problem are protecting themselves: we document everything, handle the cleaning and exclusion, and you keep your paperwork straight. We’re an independent Icynene service provider, so we won’t steer you toward a claim we know won’t fly. We’ll tell you the truth.

Our Icynene Attic Cleaning & Rodent Proofing Process

Every job starts with a phone call and ends with a walkthrough. Here’s how a standard Icynene attic cleanout and rodent proofing goes in Fullerton:

1. 1
   Call and talk to a person. You reach us directly, any hour. We’ll ask about what you’re hearing, what you’re smelling, and when the foam was installed.
2. 2
   Inspection and estimate. We come out, get into the attic, inspect the foam condition, identify entry points, and map out what needs to come out. You get an upfront price before any work starts.
3. 3
   Contaminated foam removal. We cut out urine-soaked, tunneled, or delaminated Icynene foam, bag it in the attic, and haul it out. We wear full PPE, and we lay down containment so nothing spreads into your living space.
4. 4
   Sanitizing and decontamination. We treat the remaining surfaces with an antimicrobial and enzyme-based cleaner that actually breaks down rodent waste. A simple bleach wipe-down won’t cut it on open-cell foam.
5. 5
   Exclusion sealing. This is the part most attic cleaning companies skip. We seal every possible entry point - soffit gaps, roof intersections, pipe penetrations, gable vents with damaged screens - using rodent-proof materials. If we don’t do this, the rats come back.
6. 6
   Re-foaming, patching, and final walkthrough. We replace the damaged Icynene with fresh spray foam (or another material of your choice), clean up, and walk you through the attic so you can see exactly what was done. Every job is backed by the Done Right Promise: if it’s not done right, we make it right.

What Icynene Attic Cleaning & Rodent Proofing Costs in Fullerton

Here are real, honest numbers for what Fullerton homeowners typically pay for Icynene attic work with us. No vague quotes, no surprises.

• Basic attic inspection and spot rodent entry sealing: $350 to $800
• Partial Icynene foam removal and localized sanitizing: $900 to $1,800
• Full attic cleanout with complete foam removal, sanitizing, and exclusion: $1,800 to $3,500
• Complete cleanout plus re-foaming with new Icynene: $3,000 to $4,500+ depending on square footage and foam depth

What moves the price: how much foam is contaminated, how long rodents have been active, how many entry points need sealing, and whether your attic is a tight, low-clearance space or a walkable one. Fullerton ranch homes from the 1960s and 1970s often have shallower attics that take longer to work in. We give you the price before we start, and we honor it. Call (657) 216-9948 for a free estimate, and remember: seniors and veterans always get 10% off, and we offer a free second opinion on any written estimate you already have.

Why Fullerton Homeowners Call Walt’s Insulation for Icynene Work

There are bigger companies out there. But the one down the road is the one that will show up when there’s a problem. We’re locally owned and owner-operated since 2000, with a published address and license number. Walt Brenner started this business because he got tired of watching homeowners get run around by companies that sold them a job and disappeared. He still answers the phone himself more often than not.

When we send a technician to your Fullerton home, you get a background-checked, uniformed person whose name you’ll know before they arrive. We work on Icynene foam every month, and we also handle other major spray foam and insulation brands including Owens Corning, Rockwool, Johns Manville, CertainTeed, Demilec, Knauf, GreenFiber, and Reflectix. That matters when your repair involves matching an older foam or choosing a better material for your situation. We do the job right the first time - because we’re the ones who have to stand behind it. That’s the Done Right Promise, and it’s good for life.
