Icynene Attic Cleaning & Rodent Proofing in Glendale: What to Know First
Icynene attic cleaning and rodent proofing in Glendale typically runs between $1,800 and $4,500 depending on attic size, contamination level, and how much exclusion work is needed. Most jobs take one to two days, and we can usually get a crew to your home within 48 hours. Call (747) 246-7237 for an exact quote based on what’s actually up there.
This page is written for homeowners in Glendale who have Icynene spray foam insulation, open-cell or closed-cell, and have discovered rodent activity, odors, or just years of accumulated dust and debris in the attic. If you’re not sure which Icynene product you have, that’s fine. We’ll identify it when we inspect. What matters is that you’re dealing with a foam product that needs different handling than fiberglass or cellulose, and most attic cleaning companies don’t know the difference.
Since 2000, Walt’s Insulation has worked on Icynene attics across Glendale, from the hills above Brand Boulevard to the flats near Glendale Community College. We’re an independent Icynene service provider, not a manufacturer affiliate, which means we answer to you, not a warranty department.
How Icynene Products Fail - and How We Fix Them
Icynene is a solid product, but it’s not indestructible. In Glendale’s heat, where attic temperatures regularly hit 140°F in August, we see the same failure patterns year after year. Here’s what we find and what we do about it:
- Icynene Classic (open-cell) absorbs rodent urine and droppings deep into the foam matrix. Open-cell foam is spongy. Rats and mice burrow tunnels through it, nesting inside the foam itself. Urine soaks in and the ammonia smell can’t be surface-cleaned. The fix is cutting out the contaminated section, sanitizing the area, and replacing with new foam or, where the homeowner prefers, upgrading to a closed-cell product like Icynene ProSeal. We map the damage before we cut so you’re not paying to replace foam that’s still clean.
- Icynene ProSeal (closed-cell) hides rodent entry points behind its rigid shell. Closed-cell foam is dense and rodents can’t burrow into it the way they do open-cell. But they do chew along the edges where foam meets framing, and the entry holes are often hidden behind the rigid foam surface. We inspect the full perimeter with a borescope camera before assuming we’ve found every gap.
- Icynene ProSeal LE edges pull away from rafters in Glendale’s dry heat cycles. Glendale gets big temperature swings between day and night, summer and winter. That expansion and contraction causes closed-cell foam to separate from wood framing over time, leaving hairline gaps that rodents exploit. Mice can squeeze through a gap the size of a dime. We refoam those edges and, in attics that show significant separation, we recommend adding a mechanical exclusion barrier like steel mesh over the re-foamed joints.
- Icynene LD-C-50 (low-density open-cell) is a dust magnet in attics with older roofing. Low-density foam has a rougher surface texture that traps dust from fiberglass-based roofing underlayment that breaks down over the years. In Glendale homes built before 1990, we often see LD-C-50 attics with a thick gray coating of degraded underlayment dust on the foam surface. Cleaning requires a HEPA vacuum with a soft brush attachment, not the standard attic cleaning equipment most crews bring, because aggressive brushing tears the open-cell foam.
- Rodent damage to Icynene foam is rarely covered by the manufacturer’s warranty. Icynene’s warranty covers manufacturing defects, not animal intrusion. Most homeowners don’t realize this until they file a claim. We handle warranty documentation as an independent contractor, but we’re straight with you: rodent damage out of warranty still needs to be fixed, and ignoring it means the damage spreads. We’ll give you a written scope and price before we touch anything.
Our Icynene Attic Cleaning & Rodent Proofing Process
Every Icynene attic job follows the same sequence. It’s not complicated. It’s thorough. Do it right the first time or you’ll be doing it twice, and the second time costs more.
- 1
Inspection and mapping. We document the foam type, the extent of contamination, all entry points, and any previous repair attempts. You get photos and a scope of work before we start.
- 2
Exclusion first. Rodent proofing happens before cleaning, not after. We seal every entry point at the roofline, utility penetrations, and gable vents using steel mesh, exclusion sealant, and foam compatible with your existing Icynene product.
- 3
Contaminated foam removal. We cut out saturated sections of open-cell foam using a clean, controlled removal process. Closed-cell foam usually stays unless it’s been structurally compromised by chewing or separation.
- 4
HEPA sanitation and decontamination. The entire attic gets vacuumed and treated. We use a hospital-grade disinfectant rated for the bacteria in rodent waste, not just an odor mask. For open-cell foam surfaces, we use soft-brush HEPA equipment so we don’t shred the foam.
- 5
Foam replacement and repair. Damaged sections are re-foamed. Where you have open-cell Classic and want better rodent resistance, we discuss upgrading to closed-cell ProSeal. The decision is yours; the quote is itemized either way.
- 6
Final inspection and warranty walk-through. We walk the attic with you or send photos of every step we took. The work is covered by our lifetime Done Right Promise. If it’s not done right, we make it right, no runaround.
What Icynene Attic Cleaning & Rodent Proofing Costs in Glendale
Here’s what we quote most often in Glendale. Every price includes labor, materials, and the cleanup, but your exact number depends on attic size, foam type, and how long the rodents have been up there.
- Attic cleanup only, no rodent work: $900 to $1,800 for a typical 1,200 to 1,800 square foot Glendale attic.
- Rodent proofing and exclusion, no foam damage: $1,200 to $2,500, depending on entry point count and roofline complexity.
- Full cleanout with contaminated open-cell foam removal and replacement: $3,500 to $6,000, with the high end for attics with widespread Icynene Classic saturation.
- Attic sanitizing and decontamination only: $700 to $1,400, including HEPA vacuuming and disinfectant treatment.
What moves the price is foam contamination extent, attic accessibility, and how many entry points need exclusion. We give you a written, line-item quote before we start. No surprises at the end. Call (747) 246-7237 and we’ll send a technician out. The estimate is free, and if you have a written quote from another company, we’ll give you a free second opinion on it.
Why Glendale Homeowners Call Walt’s Insulation for Icynene Work
We’re the one down the road, not a franchise with a call center in another state. Walt Brenner started this business in 2000 after learning the trade fundamentals at St. Philip’s College and has been working Glendale attics long enough to know which blocks have original 1960s roof decking and which tract was re-roofed after the 1994 Northridge quake. That local knowledge matters when you’re tracing rodent entry points on a 45-degree Spanish tile roof near Adams Hill.
Every technician who walks into your home is background-checked and wearing a uniform with our name on it. We answer the phone live, 24/7. Not a voicemail, not an answering service. You call, a person picks up. And if you have Reflectix radiant barrier in the same attic, we service that too, because a lot of Glendale homes have a combination of products from different installation eras, and it’s easier for you if one crew understands all of it.
We install and service products from Owens Corning, Rockwool, Icynene, Johns Manville, CertainTeed, Demilec, Knauf, and GreenFiber. That means we don’t have one brand to push. We have the one that’s right for your attic. Seniors and veterans always get 10% off. Any repair over $200 takes $40 off. No trip charge if you’re inside the service county.
FAQs
Yes, rodent urine and droppings in and around Icynene foam create a health hazard that requires professional attention with proper protective equipment and hospital-grade disinfectants, not just a dust mask and some bleach. We wear full PPE, use HEPA filtration, and treat the area so it’s safe to be in your home while we work.
No, Icynene’s manufacturer warranty covers manufacturing defects, not animal intrusion, so rodent cleanup and foam replacement comes out of your pocket or your homeowners insurance. We’ll document everything for your insurance claim if you file one, but the fastest path is usually getting the work done and moving on. Call (747) 246-7237 and we’ll tell you what we’re seeing before you commit to anything.
Yes, when the contamination is surface-level, we can HEPA vacuum and disinfect open-cell Icynene foam while leaving it in place. When rodent urine has soaked into the foam matrix, though, no surface cleaning removes the ammonia odor, and the contaminated sections have to come out. We’ll show you the difference before we recommend removal.
We’re usually on a Glendale roof within 48 hours of your call, and for active rodent infestations we can often schedule same-week. If you hear scratching at 2 a.m., call (747) 246-7237. A live person answers, even at 2 a.m.
It’s cheaper now, every time. Rodents don’t stop, and every week they’re active means more contaminated foam, more chewed wiring, and more entry points to seal. A $1,500 exclusion job becomes a $5,000 foam replacement in a season. Call us at (747) 246-7237 for a free estimate and we’ll show you exactly what you’re looking at.
Yes, we service and install products from Owens Corning, Rockwool, Johns Manville, CertainTeed, Demilec, Knauf, and GreenFiber, along with Reflectix radiant barrier.
