Icynene Attic Cleaning & Rodent Proofing in West Hollywood: What to Know First
Icynene attic cleaning and rodent proofing in West Hollywood typically runs $1,400 to $3,800 depending on attic size and contamination level, with most jobs completed in one to two days. We’re an independent Icynene service provider, not a factory crew, so we call it like we see it, fix what’s actually broken, and stand behind the work with our lifetime Done Right Promise. If you own a West Hollywood home with Icynene spray foam and you’ve heard scratching overhead or found droppings near your hatch, this page tells you exactly what you’re dealing with. Call (213) 527-4062 any hour, a live person picks up.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic (open-cell) soaks up rodent urine like a sponge. Open-cell foam is roughly 60% air by volume, which made it great for sound dampening in older West Hollywood condos near Santa Monica Boulevard, but it’s porous. When rats or mice nest in it, urine saturates deep. Surface cleaning won’t touch it. We cut out the contaminated foam, sanitize the decking beneath, and reapply a compatible open-cell product so you’re not left with a smell that comes back every warm afternoon.
- Icynene ProSeal seams pull away from rafters in dry heat. West Hollywood’s late-summer Santa Ana stretches put real stress on spray foam adhesion. ProSeal and similar closed-cell lines expand and contract at a different rate than the framing. When hairline gaps open at the seam, rodents exploit them. We inspect every linear foot of foam-to-wood contact, remove the failed section, and re-foam with proper surface prep so the next rodent doesn’t find an open door.
- Rodents tunnel through Icynene’s softer open-cell blends in weeks, not months. Unlike fiberglass batts that just get flattened, open-cell Icynene gets excavated. Rats carve nesting chambers right into the foam, leaving a honeycomb of tunnels. You can’t patch tunnels with canned foam and call it done. We cut back to solid, uncontaminated foam, rebuild the section, and then address the entry point, because if you skip step two, they’ll just tunnel the new foam too.
- Icynene closed-cell hides roof leak damage until the decking rots. Closed-cell foam seals so well that a small roof leak can sit trapped between the foam and the roof sheathing for a year before you see a ceiling stain. By the time we’re called for attic cleaning, we often find soft decking behind what looked like a small stain. We’ll tell you before we start cutting, because we don’t want you paying for cleaning twice.
- Old Icynene installs in West Hollywood often skipped rodent exclusion entirely. A lot of the foam work done during the 2000s condo conversion boom was insulation-only, no wire mesh, no gap sealing at the eaves. The foam does not stop rodents. We pull the contaminated material, then rebuild the attic’s defenses the way it should have been done the first time, sealing every penetration from the vent stacks to the chase ways.
Our Icynene Attic Cleaning & Rodent Proofing Process
- 1
We inspect the entire attic. We check foam condition, look for tunnels and urine stains, map entry points, and document everything so you know what we found and why we’re recommending what we are.
- 2
We give you a written price. Not an estimate, a price. If you have another written estimate, we’ll give you a free second opinion. No trip charge inside Los Angeles County, $40 off any repair over $200.
- 3
We remove contaminated or damaged Icynene. We cut out only what’s compromised. Clean foam stays. We bag and remove everything the same day.
- 4
We sanitize and decontaminate. Decking, framing, and any remaining foam get treated for bacteria and odor. We don’t mask with fragrance, we kill the source.
- 5
We seal entry points. Steel mesh, flashing, and foam-compatible sealants close off every gap a rodent can squeeze through. A full-grown rat needs a hole the size of a quarter. We treat anything bigger than a dime.
- 6
We test and walk you through it. We re-inspect the full perimeter, show you before and after photos, and you’re covered by the Done Right Promise for as long as you own the home.
We do the job right the first time - because coming back to fix it isn’t good for either of us.
What Icynene Attic Cleaning & Rodent Proofing Costs in West Hollywood
Here’s the straight talk on what we see across West Hollywood attics, from the compact bungalows off Fairfax to the larger properties tucked behind the Sunset Strip:
- Light contamination, small attic (under 1,000 sq ft): $1,400 - $2,200
- Moderate rodent damage, partial foam removal, standard attic: $2,300 - $3,100
- Heavy contamination, full foam removal, re-insulation, complete exclusion: $3,200 - $4,800
- Emergency same-day response for active infestation: add $150 - $300, depending on schedule
What moves the price is how much foam has to come out, how much new foam or insulation goes back in, and how many entry points need sealing. Steep roofs and tight access add labor. We’ll give you a number that doesn’t change when the crew shows up. Call (213) 527-4062 and we’ll come look, on our dime if you’re in the county.
Why West Hollywood Homeowners Call Walt’s Insulation for Icynene Work
We’ve been doing this since 2000, and we’ve cleaned more Icynene attics in West Hollywood than we can count, including plenty of older buildings along the Santa Monica Boulevard corridor where the original foam job was, to put it charitably, an afterthought. Walt Brenner himself grew up in the trade, learned it properly before heading west, and still gets on the phone when you call. You get a background-checked, uniformed tech at your door, not a rotating cast of subcontractors. We work with Icynene, Owens Corning, Rockwool, Johns Manville, CertainTeed, Demilec, Knauf, GreenFiber, and Reflectix, so if your repair calls for a different material than what’s up there now, we’ll tell you and explain why. We’re the one down the road. That’s the point.
FAQs
No. We’re an independent Icynene service provider, and our cleaning methods don’t void the manufacturer’s material warranty. What voided it was probably the rodents, since no foam warranty covers animal damage. We document everything so you have a clear record if you ever file a claim.
Usually, yes. Most West Hollywood attics we see need partial removal, not a full gut. We cut out only the contaminated or tunneled foam, sanitize what remains, and patch in new material. A full removal only makes sense when contamination is widespread or the original install was poorly done. Call (213) 527-4062 and we’ll tell you which camp you’re in.
Same-day and next-day appointments are normal for active infestations. We answer the phone live at (213) 527-4062, 24/7, so you won’t leave a message and hope someone calls back by Thursday.
Cleaning and proofing is almost always cheaper when the foam is in good structural shape. A full Icynene removal and re-spray runs at the top of the range, $3,200 and up. We’ll show you the numbers for both options and let you decide. We don’t push replacements just because they’re a bigger invoice.
Yes. It’s a permanent 10% off for seniors and veterans, applied to any job we do, including attic cleaning and rodent proofing. Just mention it when you call, and it comes off the final invoice.
