This page is for West Hollywood homeowners who already have Icynene in their walls or are considering it for a retrofit. We’ll cover what goes wrong, what it costs, and how we approach the work differently than the chain that originally sold it to you.

How Icynene Products Fail - and How We Fix Them

Icynene open-cell and closed-cell spray foams are solid products, but they’re only as good as the installation and the building around them. In West Hollywood, we see the same failure patterns repeat across older stucco and wood-frame homes near the Santa Monica Boulevard corridor and up in the hills. Here’s what we find:

• Icynene Classic (open-cell) shrinkage gaps at stud bays. Open-cell foam can pull away from framing as it cures if the substrate was too cold or dusty during the original install. We see hairline gaps along studs in West Hollywood homes built before 1990. The fix is a targeted injection of compatible open-cell foam into the void, not a full tear-out. We check with a thermal camera first so we’re not guessing.
• Icynene ProSeal (closed-cell) density problems near window headers. Closed-cell foam sprayed too thin doesn’t hit its R-value. We’ve measured ProSeal installations at 1.2 to 1.5 inches when the spec called for 2 inches, especially around window and door headers where installers rush. Our fix is usually a drill-and-fill supplement with Demilec or Icynene closed-cell, depending on what’s compatible with the existing foam.
• Moisture trapping from missing vapor management. Open-cell Icynene is vapor-permeable, which is fine in a ventilated wall assembly, but some West Hollywood homes got it installed directly against stucco without proper drainage plane details. That’s not an Icynene defect, it’s an installation flaw, and it leads to musty smells and degraded foam at the base of walls. We address the water entry source first, then repair or replace the affected foam. We don’t just mask it.
• Rodent and pest tunneling through open-cell foam. Rats and mice in the Hollywood Hills chew through open-cell Icynene like it’s nothing. We regularly pull damaged foam from wall cavities in homes near Runyon Canyon and the Bird Streets where rodent pressure is real. After we remove and replace the damaged material, we seal entry points and recommend a pest exclusion plan so you’re not paying twice.
• Sound transmission complaints with Icynene open-cell in interior walls. Homeowners often expect open-cell spray foam to block noise between rooms, but open-cell Icynene is a mediocre sound barrier compared to Rockwool or a dense-pack cellulose. If you’re soundproofing a home office or bedroom wall in a West Hollywood condo or duplex, we’ll tell you straight: adding Rockwool safe’n’sound or GreenFiber dense-pack to the cavity typically outperforms a foam-only solution. We install what actually works for the job, not what’s easiest for us.

Our Icynene Wall Insulation Process

Here’s how a typical Icynene wall job goes from the first call to cleanup:

1. 1
   You call (213) 527-4062. Walt or one of our senior techs answers, live. We ask about your home’s age, the wall in question, and what symptoms you’re noticing. That conversation usually tells us whether we’re sending someone out for a diagnostic visit or a full inspection.
2. 2
   We inspect the wall and take measurements. We use a thermal camera and, when needed, a borescope through a small access hole to see what’s actually inside the cavity. We check foam depth, adhesion, moisture levels, and whether the original install left gaps.
3. 3
   We give you a written quote with a real number. No vague ranges, no “we’ll see when we open it up” line. If another company has already quoted you, bring it in. We’ll give you a free second opinion on any written estimate.
4. 4
   We do the work. Depending on what we found, that means drill-and-fill injection foam, targeted removal and re-spray, or a full cavity flush. We protect your floors and furniture, and we keep the work area contained so foam dust doesn’t migrate through the house.
5. 5
   We test and verify before we pack up. We re-scan the wall with the thermal camera to confirm the cavity is filled and there are no dead spots. If it’s not right, we fix it before we leave.
6. 6
   Every job is covered by the Done Right Promise. That’s our lifetime workmanship guarantee. If something isn’t right, we come back and make it right. No runaround, no fine print games.

What Icynene Wall Insulation Costs in West Hollywood

Here are realistic numbers for the most common Icynene wall jobs we handle in West Hollywood:

• Drill-and-fill supplement for one wall (open-cell gaps, 20-30 linear feet): $700-$1,400
• Full exterior wall retrofit, single-story home (1,200-1,800 sq ft): $2,800-$4,200
• Interior soundproofing wall (one shared wall in a condo or duplex): $900-$1,800
• Rodent damage removal and foam replacement (one wall section): $1,100-$2,200
• Moisture remediation plus foam replacement (base of wall, stucco home): $1,400-$2,800

What moves the price: access (interior walls with drywall removal cost more than exterior drill-and-fill), the extent of existing foam damage, and whether we’re matching open-cell or closed-cell material. Every job gets a written quote before we touch anything. If you have a repair over $200, we take $40 off. Call (213) 527-4062 for an exact number.

Why West Hollywood Homeowners Call Walt’s Insulation for Icynene Work

We’re the one down the road, not an 800 number in another state. Walt’s Insulation has been locally owned and owner-operated since 2000, with a published address and license number you can look up. When you call us, a live person answers, 24/7. Not a voicemail, not a call center script. The technicians who show up at your door are background-checked and uniformed, and they know Icynene because we’ve been installing and repairing it across West Hollywood for years. We also service other brands including Reflectix, Owens Corning, Rockwool, and Demilec, so if Icynene isn’t the right fit for your wall, we’ll tell you that instead of forcing it. We do the job right the first time, because coming back to fix it isn’t good for either of us.
