Icynene Spray Foam Insulation in Glendale: What to Know First
We provide independent Icynene spray foam insulation in Glendale, typically with same-day or next-day turnaround for standard jobs and a written price delivered before any work starts. Most Icynene open-cell and closed-cell repairs in a Glendale home run between $1,800 and $4,500 depending on cavity access and the extent of degradation. This page is for homeowners who already have Icynene foam in their walls, attic, or roof deck and need to know whether it can be repaired, topped off, or fully removed and replaced.

How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell) shrinkage in roof decks. The Classic Max line can pull away from rafter bays in Glendale’s dry summer heat, creating a gap that vents conditioned air straight into the attic. We find this most often in homes built between 2012 and 2018 near the Chevy Chase Canyon area. Our fix: mechanical removal of the separated foam, reconditioning the substrate, and reapplication with proper humidity control during cure.
- Icynene MD-R-200 (closed-cell) off-ratio curing from temperature swings. When the B-side isocyanate doesn’t fully react due to cold substrate conditions during original install, the foam stays soft and may emit odor. We core-sample suspect areas, identify off-ratio sections with a durometer reading, and cut out only the compromised material rather than stripping the whole cavity.
- Icynene LD-C-50 (low-density open-cell) moisture retention in balloon-frame walls. Older Glendale homes near the Verdugo Woodlands with balloon framing can trap humidity behind LD-C-50 if the exterior clapboard isn’t properly back-primed. We pull back the foam at the base of stud bays, inspect for sheathing rot, and replace with a vapor-smart closed-cell application at the lower third if the wall assembly demands it.
- Icynene Waterblown .5 (legacy product) powdering and dust release. Discontinued in the mid-2010s, this early waterblown formula can degrade to a friable dust in hot attic conditions. We treat this as a hazardous removal job, using HEPA-contained extraction and full personal protective equipment, then replace with current-spec open-cell or dense-pack cellulose depending on the attic ventilation strategy.
- Icynene ProSeal Eco (closed-cell) delamination from OSB roof sheathing. The high-adhesion ProSeal line can actually tear the surface layer off OSB if the panel was wet during install or if roof leaks developed later. We remove the failed foam, assess sheathing integrity, replace compromised panels, and refoam with a primer-sealed substrate and staged cure cycles.
Our Icynene Spray Foam Insulation Process
- 1
Call and scope. A live person answers 24/7. We schedule a site visit, and you receive a text with the technician’s name when they’re en route.
- 2
Blower-door test and thermal imaging. We pressurize the house to measure CFM50 leakage, then use FLIR to map where the Icynene foam has failed, shrunk, or delaminated. Seal the bypasses first. Insulation over air leaks is just expensive noise reduction.
- 3
Core sampling and material identification. We extract small foam cores to confirm the Icynene product line and check for off-ratio cure or moisture intrusion. This determines whether repair, spot removal, or full replacement is warranted.
- 4
Written price and material selection. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. For Icynene jobs, we use OEM-spec replacement foam or equivalent-density product from Demilec or Johns Manville when the original line is discontinued.
- 5
Execution and documentation. The crew completes the work, performs a post-installation blower-door test, and delivers a Documented Photo Record plus printed pre- and post-ACH50 readings.
- 6
365-Day Done Right Promise activation. The written warranty is in effect. If the ACH50 doesn’t hold or the foam fails, we make it right.
Before
AfterWhat Icynene Spray Foam Insulation Costs in Glendale
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Spot repair, open-cell (1-2 rafter bays) | $1,800 - $2,800 | Cavity access, scaffolding, extent of degraded foam |
| Closed-cell removal and replacement, rim joist | $2,400 - $3,800 | Crawl space clearance, off-ratio sections, vapor barrier integration |
| Full attic removal and refoam (Icynene legacy product) | $4,200 - $7,500 | Attic square footage, HEPA containment requirement, sheathing repairs |
| Roof deck refoam, open-cell | $3,500 - $6,200 | Roof pitch, ventilation strategy, whether tear-off is concurrent |
Most Glendale Icynene jobs fall in the $2,200-$4,100 band for partial repairs with documented blower-door verification. Full removals cost more because of containment labor and disposal fees for legacy foam. We also service Reflectix radiant barrier systems if your assembly combines foam with reflective insulation.

Why Glendale Homeowners Call Topside Attic Insulation Glendale for Icynene Work
We’ve been running jobs across Glendale since 2016, including older ranch-style homes near the Verdugo Woodlands where dense-pack cellulose in balloon-frame walls is still the right call. Wes Okafor learned the trade at Richard J. Daley College, where the curriculum was heavy on air sealing before it was fashionable anywhere, and his crew still won’t open a bag of insulation until the blower-door test shows where the air is actually going.
Every Icynene job closes with a Documented Photo Record and printed pre- and post-ACH50 numbers. The 365-Day Done Right Promise is backed by a written scope delivered before work starts. Our materials come from Icynene, Demilec, Johns Manville, and other named manufacturers - no proprietary lock-in, no upsell to a “preferred” product line. As an independent Icynene service provider, we fix what’s actually broken rather than what a brand manual says to sell.
FAQs
The original Icynene install warranty, typically 10 years on product and workmanship, covers defects in the original application - it does not cover damage from roof leaks, rodent intrusion, or subsequent remodeling. Our repairs come with their own written warranty under the 365-Day Done Right Promise, and we document whether the failure was original-defect or post-install damage so you have a clear chain of evidence if a claim is warranted. Call (213) 474-3828 and we’ll review your paperwork with you.
We use current-spec Icynene product when the line is still in production; for discontinued formulations like Waterblown .5, we match density and closed-cell content with equivalent foam from Demilec or Johns Manville and document the substitution in your written scope. This keeps the assembly performance-neutral without chasing obsolete stock. For an exact read on what’s available for your product line, call (213) 474-3828.
Spot repair is cheaper when the failure is localized shrinkage or delamination in accessible cavities - typically 40-60% less than full removal. Full removal and replacement is the better economic choice when the foam is friable legacy product, when off-ratio curing is widespread, or when the attic has multiple failure modes that would require sequential repairs. We quote both paths when both are viable. Call (213) 474-3828 for a written comparison.
Most spot repairs are done in one day; full attic removals with refoam take two to three days depending on containment setup and cure time. We schedule same-day or next-day site visits, and the written price arrives within 24 hours of that visit. Call (213) 474-3828 to book.
Yes - we service Reflectix radiant barrier installations and can assess whether the reflective layer is properly integrated with your Icynene foam or creating a moisture trap at the assembly boundary. The photo record and blower-door test cover the full envelope, not just the foam. Call (213) 474-3828 for a free estimate.
