Icynene Attic Cleaning & Rodent Proofing in Santa Monica: What to Know First
Icynene attic cleaning and rodent proofing in Santa Monica typically runs $1,200 to $3,800 depending on attic size, contamination level, and whether rodents have chewed through the foam. Most jobs take one to two days, and we can usually start within three to five business days. If you’re hearing scratching above the bedroom or you’ve found droppings near your attic hatch, call us at (424) 396-5828 and a live person will pick up, day or night.
This page is for Santa Monica homeowners with Icynene spray foam insulation who’ve discovered that rodents don’t care how much you paid for your attic. Raccoons, roof rats, and squirrels chew through open-cell Icynene like it’s a soft cheese course. We’re an independent Icynene service provider, not a manufacturer rep, which means we’ll tell you what’s actually going on up there, not what corporate wants us to say. As Walt Brenner will tell you, spray foam makes a comfortable attic, and rodents are happy to take advantage of that comfort too.
How Icynene Products Fail - and How We Fix Them
Spray foam is excellent insulation. It’s also a material with real failure points in the Santa Monica climate, and when rodents get involved, those failures get expensive. Here’s what we see on Icynene jobs in this city, week after week.
- Open-cell Icynene Classic chewed into tunnels. The Classic line is soft, open-cell foam. Roof rats in the palms that line San Vicente and the streets around Montana Avenue burrow straight through it, creating tunnel networks that destroy the air seal. We remove the damaged foam, address the entry points, and re-insulate with Icynene or another brand that fits the cavity.
- Closed-cell Icynene ProSeal lifting from roof sheathing. ProSeal is rigid, closed-cell foam. When it loses adhesion, often due to moisture cycling from the marine layer working against the sheathing, gaps form at the foam-to-wood junction. Rodents exploit those gaps. We cut out the separated foam and re-seal, then verify the roofline is dry so it doesn’t happen twice.
- Contaminated foam from urine saturation. Rodent urine soaks into open-cell foam and stays there. You can’t steam-clean it out, despite what YouTube suggests. In Santa Monica’s damp attic conditions, that contamination breeds odor and mold. We remove the saturated foam down to the framing, sanitize, and replace with fresh Icynene or a rodent-resistant alternative if that’s what the job calls for.
- Electrical gnawing near foam edges. Santa Monica has a lot of older wiring running through attics, especially in the bungalows north of Wilshire. Rodents gnaw wiring next to foam edges, which is a fire risk. During every Icynene attic cleaning, we inspect wiring paths, flag damaged conductors, and recommend an electrician before foam goes back in.
- Attic hatch and soffit gaps inviting re-entry. If the foam is intact but rodents keep returning, the problem is almost always a gap elsewhere. We see it constantly on Santa Monica homes with older soffits or unsealed vent screens. Rodent proofing isn’t just patching foam; it’s sealing every opening bigger than a dime around the attic perimeter.
Our Icynene Attic Cleaning & Rodent Proofing Process
Every job follows the same discipline, whether you have a small area of open-cell Icynene in a Sunset Park bungalow or a full closed-cell attic near Ocean Park. The goal is the same: get the attic clean, keep the rodents out, and do it right the first time. That last part matters, because a second visit is always more expensive and more frustrating.
- 1
We inspect and document everything. Before touching the foam, we map the damage: type of foam, extent of contamination, entry points, nesting areas, and any electrical or framing concerns. You get photos of what we find. No mystery quotes.
- 2
We decide what stays and what goes. Not every damaged section needs removal. Some closed-cell Icynene can be repaired with proper prep and compatible foam. Contaminated open-cell foam almost always comes out. We’ll tell you the honest answer, even when it means less work for us.
- 3
We clean and sanitize. We remove droppings, nesting material, and contaminated insulation, then vacuum and sanitize the affected areas and any surfaces in the living space where odors are migrating. We use proper containment, negative pressure when needed, and personal protection on every job, every time.
- 4
We seal entry points. This is the difference between a cleanup and a fix. We close gaps at the roofline, soffits, vents, and utility penetrations using materials appropriate to each opening. This is where most companies save time, and it is why their customers call someone else six months later.
- 5
We restore the insulation and air seal. Depending on what we find, we refresh the Icynene where needed, and if the existing foam has failed beyond saving, we’ll recommend the best insulation fit for a Santa Monica attic. Around here, the marine air means your attic seal needs to be genuinely tight, not just visually complete.
- 6
We test and walk you through it. We verify the attic is clean, the entries are closed, and the air seal is restored. Then we walk you through what we did and what to watch for. If anything returns, the Done Right Promise applies for the life of the workmanship.
What Icynene Attic Cleaning & Rodent Proofing Costs in Santa Monica
Here’s an honest look at pricing for the jobs we do most often in Santa Monica. These are real ranges from real jobs, not bait numbers. The final price depends on attic size, access, foam type, and how thorough the rodents were.
- Inspection and assessment: Free with any booked service. No trip charge in Los Angeles County.
- Localized Icynene repair and spot cleaning (small area, minor damage): $800-$1,500
- Full Icynene attic cleanout with sanitizing (average Santa Monica home): $1,500-$2,800
- Cleanout plus full rodent proofing and exclusion: $2,500-$4,500
- Complete contaminated Icynene removal and re-insulation: $4,000-$8,000+ depending on attic size and foam type
What moves the price is the square footage of attic, how much foam is contaminated, whether we’re doing crawl space work too, and how many entry points need sealing. We give you a written estimate before the work starts, and it’s the number you pay. No add-on surprises at the end. Call (424) 396-5828 for a free estimate.

FAQs
Icynene foam itself doesn’t attract rodents, but it does create a warm, stable attic environment they like once they find a way in. The foam is not a food source, but rodents will burrow through open-cell Icynene Classic to create nesting galleries. If you’ve got foam and rodents, the issue is usually an entry point, not the product. Call (424) 396-5828 for an inspection.
Surface-cleaned Icynene can sometimes be saved, but urine-saturated open-cell foam cannot be cleaned effectively and should be removed. Rodent urine penetrates deep into the foam’s cell structure, and no surface treatment reaches it. We’ll tell you what can stay and what needs to come out after we inspect.
We’re an independent Icynene service provider, so our work doesn’t void your manufacturer’s warranty, but the warranty itself typically covers material defects, not rodent damage. Rodent chewing and urine contamination are almost never covered by any foam manufacturer’s warranty. That’s why exclusion and proofing matter so much.
Most Icynene attic cleaning and rodent proofing jobs start within three to five business days in Santa Monica, and we can often begin sooner for active infestations. If you’ve got rodents actively chewing wiring or you’re hearing them at night, call (424) 396-5828 and we’ll get you on the schedule fast.
It depends on the schedule, but we always answer live, even at 2 a.m., and we’ll tell you honestly when we can be there. If it’s an emergency, we’ll do everything we can to move things around. Call (424) 396-5828 and ask for the next available slot.
