Icynene Spray Foam Insulation in Glendale: What to Know First

Icynene spray foam insulation in Glendale typically runs $2.50 to $6.50 per board foot installed, depending on whether you’re getting open-cell or closed-cell foam, and most jobs wrap up in one to two days. We’re an independent Icynene service provider, not a factory-authorized dealer, which means we call problems the way we see them and fix them the right way rather than the corporate-policy way.

This page is for Glendale homeowners who already have Icynene foam in their walls, attic, or rim joists and need someone who actually understands how this specific product behaves in the San Fernando Valley heat. If your Icynene is pulling away from framing, sweating in the summer, or just not performing the way the original salesperson promised, call us at (747) 246-7237 and a live person picks up. Walt’s Insulation has been doing this work since 2000, and Walt Brenner still runs the show personally.

How Icynene Products Fail - and How We Fix Them

• Icynene Classic Plus (open-cell) pulling back from rafters in Glendale attics. The original Classic line has a softer, spongier cell structure than newer formulations, and after years of 100-degree-plus attic cycles, it can shrink slightly and detach from the wood. That gap becomes a thermal bypass. We cut out the affected section, inspect for moisture trapped behind it, and re-spray with a compatible open-cell product, then verify the foam fully adheres across the entire bay.
• Icynene ProSeal (closed-cell) losing adhesion on the underside of roof decks. ProSeal is a great product for unconditioned attics, but we’ve seen it peel on homes near the Verdugo Mountains where winter moisture seeps into the sheathing before the foam gets applied. If the substrate wasn’t bone-dry at application, the foam can’t bond. The fix is removing the failed section, letting the sheathing dry thoroughly, and re-spraying only after moisture readings confirm it’s below the threshold.
• Icynene ProSeal LE off-gassing complaints in the first months after install. Some homeowners report a lingering chemical smell months after a ProSeal LE job. That’s almost always an install issue: the A and B sides weren’t mixed at the right ratio or the substrate temperature was too low for proper reaction. We re-test the foam density with a core sample, and if it’s under-cured, removal and re-spray is the only honest fix. A thermal camera pass tells us quickly whether the foam is curing uniformly.
• Old Icynene MD-R-200 open-cell soaking up moisture in crawl spaces. This was an early 2000s product that homeowners in Glendale’s foothill neighborhoods sometimes still find when they open up a wall. It has the consistency of a firm sponge, and if a plumbing leak or ground moisture found it, the foam holds water against framing. That’s rot waiting to happen. We remove it, dry out the cavity, fix whatever introduced the water, and replace it with closed-cell foam suited for below-grade exposure.
• Rim joist spray foam with Icynene that never fully filled the cavity. When installers rush a rim joist job, the foam can settle before it expands fully, leaving a void at the top of the cavity where cold air pours in. Homeowners feel the draft and think the Icynene failed. It didn’t fail; it was under-applied. We inspect with a thermal camera, map the voids, and fill them in. This is one of the most common callbacks we see from other companies’ work.

Our Icynene Spray Foam Insulation Process

1. 1
   You call, a person answers. That’s us, not an answering service. We talk through what you’re seeing or hearing, and we schedule a visit at a time that works for you. No trip charge inside the service county.
2. 2
   We do a full attic or wall assessment. Thermal imaging, moisture readings, and a visual inspection of the existing Icynene. We’re looking for voids, shrinkage, moisture intrusion, and air leaks around penetrations.
3. 3
   We give you a straight number. Upfront pricing, not an estimate with a question mark. If another company already gave you a written estimate, bring it. We’ll give you a free second opinion and tell you honestly if their scope makes sense.
4. 4
   We make the repair or re-spray. We use OEM Icynene products where the job calls for them, and quality compatible alternatives when they perform better or cost less. We’ll tell you which and why before we spray anything.
5. 5
   We test before we leave. Foam depth checks, density verification on closed-cell, and another thermal pass. If the numbers don’t look right, we fix it before the day is done.
6. 6
   You’re covered by the Done Right Promise. Lifetime workmanship. If it’s not done right, we make it right. No runaround, no fine print.
