How Icynene Products Fail – and How We Fix Them

Icynene makes good foam. But Los Angeles isn’t a good foam city. The heat, the salt air near the coast, the wild swing between 58-degree mornings and 104-degree afternoons in the Valley, that all puts stress on spray foam that a house in Minnesota never sees. Here’s what we actually find when an Icynene job goes wrong in LA:

• Icynene Classic Plus (open-cell) loses its air seal at the roof deck. This is the half-pound open-cell formula, and in Los Angeles attics it’s everywhere. The failure mode is delamination. Attic temps hit 140 degrees in August, the foam expands and contracts, and over five or six years it can pull away from the plywood at the edges. You lose the air barrier without seeing a visible crack. We inspect with a thermal camera, find the separation, and re-seal with fresh open-cell or a closed-cell perimeter bead, depending on the deck condition.
• Icynene ProSeal (closed-cell) gets brittle under UV exposure. Closed-cell Icynene was never meant to sit in direct sun. In LA garages and exposed rim joists, homeowners leave it uncovered because, hey, it’s foam, it looks fine. After two or three summers of direct light, the surface crusts and loses its R-value at the face. We cut back the UV-brittled layer and re-apply, then counsel you to cover it. That’s a fix Icynene’s own site won’t tell you to plan for, because most of the country doesn’t beat foam with this much sun.
• Rim joist applications shrink and leave air gaps. Icynene’s low-density open-cell can shrink as much as 2 – 3% over time, and at a rim joist that gap lets cold crawl in and warm air out. We find this on nearly every older Icynene rim joist job we open. The fix is to blow the gaps clean, recondition the surface, and apply fresh foam to restore the thermal boundary, not just caulk it and hope.
• Garage ceiling foam gets chewed by rodents. Los Angeles has a rat problem, and Icynene open-cell is soft. Rats tunnel right through it. We pull out the damaged sections, seal entry points with steel mesh where the garage meets the eaves, and re-spray. If your garage sits against a slope or overgrown brush, this will happen to you eventually.
• Knockdown and re-spray issues on older Icynene jobs. When a homeowner had a partial re-roof or electrical work done, we sometimes see sections where old Icynene was scraped out and a different foam sprayed in. Different densities don’t bond well, and you get thermal bridging at the seam. We identify the mismatch and bring the whole area back to one material, one density, one continuous envelope.

Our Icynene Spray Foam Insulation Process

Chase Whitaker has been in Los Angeles attics for going on fifteen years. He’s not guessing up there. Here’s how a typical Icynene job runs with us:

1. 1
   Call and a live person picks up. You describe the problem. We book a time, and you get a live arrival window with tech tracking, the same way you’d track a rideshare. No four-hour of silence.
2. 2
   We walk the property and diagnose. We inspect the existing foam, check density, look for delamination, UV damage, shrink gaps, and moisture. We use a thermal camera where it helps. Then we write down what’s wrong in plain English.
3. 3
   You get a written price before anything starts. No verbal number, no “we’ll see how it goes.” You approve the number. Then we work.
4. 4
   We do the repair or install. We match the correct Icynene formulation, or a compatible quality aftermarket foam if it’s a better fit for the depth and budget. The decision is made with you, not for you.
5. 5
   We test and document. We check the new foam’s depth and adhesion, then photograph everything. You get before-and-after photos in your digital invoice, which you can pay from a link.
6. 6
   You get it in writing. Every Icynene job comes with the 365-Day Done Right Promise. If it fails within the year, we return and fix it. Free. That’s a written guarantee on every repair.
