This page is for homeowners in West Hollywood, the Fairfax District, Beverly Grove, and the hills above Sunset who own Icynene-insulated homes or are considering it for a remodel. We’ll cover what actually goes wrong with Icynene foam in this climate, what repairs cost, and why we approach these jobs differently than other insulation contractors.

Key takeaways:

• We install and repair Icynene open-cell (Classic Plus, ProSeal) and closed-cell (ProSeal LE) lines.
• Most Icynene failures in West Hollywood trace to moisture, improper original installation, or settling gaps near rim joists and roof decks.
• Walt’s Insulation is a locally owned, owner-operated company with a lifetime Done Right Promise and a live person answering every call, 24/7.

How Icynene Products Fail - and How We Fix Them

Icynene foam is a solid product line, but after 25 years of crawling through attics and crawl spaces across West Hollywood, we’ve seen every way it can underperform. Here are the failures we run into most often, and what we do about each one.

• Open-cell Classic Plus moisture saturation in attic roofs. In older West Hollywood buildings, especially post-and-beam homes in the hills, we find Classic Plus open-cell foam that has wicked moisture from roof leaks or persistent condensation. Open-cell is vapor-permeable by design, which is fine in Ontario but a liability when a flat roof above Santa Monica Boulevard starts seeping. The foam darkens, holds water against the roof deck, and loses R-value fast. We remove the saturated sections, identify and seal the water source, and re-insulate with closed-cell ProSeal LE where the roof assembly can handle it.
• ProSeal shrinkage gaps where walls meet rim joists. Icynene’s early-generation open-cell formulations could settle and pull away from framing as they cured, especially in taller wall cavities. We regularly see a half-inch or wider gap running along the top plate where the foam has pulled back. That gap is a direct air-sealing failure, and air sealing is the whole point of spray foam. We cut back the affected area and re-spray, but we also check every linear foot of the rim joist while we’re in there, because if it separated in one spot, it usually separated in five.
• Overspray from sloppy original installations. A surprising amount of West Hollywood Icynene work was done during the 2005-2015 remodel boom by crews rushing through multiple units. We find foam oversprayed onto can lights, bath fan housings, and even PVC vent stacks, creating fire-safety and serviceability problems. The foam has to be carefully trimmed and, in some cases, a non-flammable barrier installed around the fixture. This is tedious work that requires patience, which is exactly what an owner-operated business can offer that a volume shop can’t.
• Premature yellowing and degradation from UV exposure. If Icynene foam is left exposed to sunlight, even through a partially open vent or a skylight well, it degrades. The surface gets powdery and friable. We see this most often in garage ceilings and knee-wall attics where access panels were left open. The fix is straightforward: remove the degraded layer, re-spray, and make sure the access that caused the UV exposure is closed properly this time.
• Under-specified foam thickness from the original installation. We’ll inspect a West Hollywood condo where the homeowner paid for R-30 closed-cell on the underside of the roof and measure just over two inches of actual foam in places, meaning they got R-13. Spray foam contractors who thin their material to stretch the job are more common than anyone wants to admit. We measure with a depth gauge and give you an honest report. If the foam is under spec, adding a layer of either Icynene ProSeal LE or another brand to bring the assembly up to code is usually the economical fix.

Our Icynene Spray Foam Insulation Process

Every Icynene job we do in West Hollywood follows the same path, whether it’s a full attic application or a targeted repair. Here’s how it works:

1. 1
   Call and talk to a person. You call (213) 527-4062 and someone picks up, day or night. We ask what’s going on, make a note, and get you on the schedule. No voicemail, no answering service.
2. 2
   On-site diagnosis. A uniformed, background-checked technician shows up on time and does a full inspection of the existing Icynene foam, including the areas you didn’t call about. We never diagnose from a photo alone.
3. 3
   Honest scope and quote. We tell you what needs to be fixed, what can wait, and what it costs. If you already have a written estimate from another contractor, we’ll give you a free second opinion on it. No trip charge in our service county.
4. 4
   The install or repair. We prep the space properly, protect your floors and belongings, and spray the foam. Every job gets the right product for the assembly, whether that’s Icynene Classic Plus, ProSeal LE, or a complementary product from Owens Corning or Demilec if the situation calls for it.
5. 5
   Verification. We check the thickness with a depth gauge, confirm the air seal is sound, and walk you through what we did before we leave.
6. 6
   Lifetime coverage. Every job is covered by our Done Right Promise. If it’s not done right, we make it right - no runaround, no fine print.

What Icynene Spray Foam Insulation Costs in West Hollywood

Here are real numbers for the Icynene jobs we do most often in West Hollywood. These reflect typical pricing in our market as of 2026:

• Open-cell Classic Plus attic application (1,200-1,500 sq ft): $2,400-$4,200
• Closed-cell ProSeal LE roof deck application (800-1,200 sq ft): $3,800-$6,500
• Rim joist spray foam in a crawl space: $1,000-$1,800
• Garage ceiling spray foam (single-car garage): $900-$1,600
• Targeted Icynene repair (moisture damage, gap filling, UV degradation): $600-$2,200 depending on access and scope

What moves the price in West Hollywood? Access is the biggest variable. Tight attics in older courtyard-style buildings, steep hillside lots where the truck can’t park close to the house, and homes with existing rodent activity that needs to be addressed before we insulate all add time and labor. Closed-cell foam costs more per board foot than open-cell, but it delivers roughly double the R-value per inch, and it’s what we recommend in West Hollywood’s mild coastal climate where roof decks and rim joists face real moisture exposure.

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

We’re the one down the road. Walt’s Insulation is a locally owned, owner-operated business, founded in 2000 and run by Walt Brenner - not a franchise with a call center in another state. We have a published address and a license number you can look up, and when you call, a live person answers. Every time. That matters when you’ve got open-cell foam crumbling in the attic and you need a straight answer at 11:00 at night.

Our technicians are background-checked and uniformed, so you know who’s walking into your home. We work with Icynene, Owens Corning, Demilec, Rockwool, and other manufacturer lines - plus Reflectix for radiant barrier applications - which means we’ll recommend the right product for the job rather than the one we happen to stock. And every single job is covered by our lifetime Done Right Promise. If it’s not done right, we make it right. No runaround, no fine print.

We have been doing this in West Hollywood long enough to know this market’s quirks: the older hillside homes above Sunset with flat roofs and minimal venting, the courtyard condos near Santa Monica Boulevard where HOA rules dictate what you can and can’t access, the mid-century post-and-beam homes where spray foam is often the only realistic way to hit modern insulation standards. This isn’t theory. We’ve done the work in these exact buildings.
