Icynene Insulation Removal & Replacement in Pomona: What to Know First
We provide independent Icynene insulation removal and replacement in Pomona, typically completing attic jobs in one to two days with a written price locked before any work starts. Most Icynene open-cell foam removals in a standard Pomona ranch run between $3,800 and $7,200 depending on thickness, contamination level, and whether the substrate needs repair. This page is for homeowners who found Icynene foam in their attic or walls - often from a 2010s energy upgrade - and now need it out due to failure, remodeling, or air-quality concerns. Call (562) 242-7569 for a free estimate with a written scope, or bring us another contractor’s quote for a free second opinion.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (MD-R-200) shrinkage and pull-away. This open-cell line was widely sprayed in Pomona Valley attics during the 2012-2018 retrofit boom. In our climate’s 100°F+ summer attic peaks, Classic Max can shrink 3-5% over five to seven years, pulling away from rafter bays and top plates. The gap looks small but creates a convection loop - hot attic air scours the conditioned side. We remove the compromised foam mechanically, repair the substrate, and replace with a product matched to the assembly and budget.
- Icynene LD-C-50 water absorption and wood rot. This lower-density open-cell formulation was sometimes used in crawl spaces and rim joists where bulk water intruded. LD-C-50 is vapor-permeable - it lets moisture pass - which is fine above grade but disastrous below. We’ve pulled saturated LD-C-50 off sill plates in Pomona’s older Ganesha Park and Lincoln Park neighborhoods where yard drainage slopes back toward the foundation. Removal exposes the rot, which we document with photos before recommending repair and a vapor-closed replacement strategy.
- Icynene H2Foam Lite (closed-cell) improper application over hot roofs. H2Foam Lite is a 2.0 lb density closed-cell product, excellent when specified correctly. Some Pomona installers sprayed it directly against roof sheathing in unvented assemblies without first calculating dew-point risk. In winter, interior moisture drives outward, hits the cold foam/sheathing interface, and condenses. We remove the foam, assess sheathing damage, and redesign the assembly - sometimes adding exterior rigid insulation, sometimes switching to a vented approach with different materials.
- Icynene Classic Max rodent infestation and bio-contamination. Open-cell foam’s texture invites nesting; we’ve found Classic Max tunneled through by roof rats in Pomona’s hillside neighborhoods near Phillips Ranch. The foam itself isn’t food, but the voids become highways. We remove contaminated sections, perform full attic cleaning and rodent proofing, and replace with a less penetrable assembly. Every job gets a Documented Photo Record showing before, during, and after.
- Icynene formulations from the 2009-2014 period with amine catalyst off-gassing. Early Icynene batches using certain tertiary amine catalysts can produce persistent odor complaints, especially in tight Pomona homes with limited ventilation. The smell isn’t dangerous at typical levels, but it’s unacceptable to live with. We remove the affected foam, ventilate the cavity thoroughly, and replace with a current-formulation product - or a different material entirely if the homeowner prefers.
Our Icynene Insulation Removal & Replacement Process

- 1
Call and scheduling. A live person answers 24/7. We book a site visit, send a text with the technician’s name when they’re en route - Haven Standard: Arrive on schedule, you get a named technician.
- 2
Assessment and blower-door baseline. Wes Okafor or a senior tech runs a blower-door test - a pressurization reading that shows, in one number, how much air the building envelope is losing. For Icynene removals, this establishes whether the foam was doing any air-sealing work we’ll need to replace. We photograph the foam condition, measure thickness, and note substrate type.
- 3
Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No work starts without it. We specify removal method (mechanical shaving, chemical-assisted, or full substrate replacement), disposal routing, replacement material, and timeline.
- 4
Removal and substrate repair. Icynene foam comes out with specialized cutting tools and HEPA-contained vacuums. We don’t grind it to dust - that spreads particles. Substrate damage from shrinkage, moisture, or removal is repaired before anything new goes in. Seal the leaks first. The insulation is just the last layer of the answer.
- 5
Replacement, air sealing, and verification. New insulation goes in only after top plates, can lights, and penetrations are sealed. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers so you can verify the performance change you paid for.
- 6
Documentation and closeout. You receive the written warranty, the Documented Photo Record, and the blower-door readings. The 365-Day Done Right Promise is in effect from day one.
Before
AfterWhat Icynene Insulation Removal & Replacement Costs in Pomona
These ranges reflect what we’ve written for actual Pomona jobs in the past eighteen months. Every home differs - roof pitch, access, contamination level, and whether the substrate needs repair all move the number.
| Scenario | Typical Range |
|---|---|
| Partial Icynene removal (contaminated or failed section, up to 300 sq ft) | $1,800 - $3,400 |
| Full attic Icynene removal, standard ranch, no substrate repair | $3,800 - $5,600 |
| Full attic removal with substrate repair/replacement | $5,200 - $7,200 |
| Closed-cell removal from roof assembly (H2Foam Lite) with redesign | $6,500 - $10,000+ |
| Crawl space Icynene removal with moisture remediation | $4,000 - $7,500 |
What moves the price: foam density (closed-cell is harder to remove), accessibility (steep roofs and tight crawl spaces add labor hours), hazardous material handling (vermiculite mixed with foam requires abatement protocol), and whether we find structural damage once the foam is out. We price for what we see, not what we hope to find. Call (562) 242-7569 for a written estimate - estimates are free, and we’ll read a competing quote with you at no charge.
Why Pomona Homeowners Call Topside Attic Insulation Pomona for Icynene Work

We’ve removed Icynene from more than 200 Pomona Valley homes since 2016 - ranch houses near Ganesha Park, two-story builds in Phillips Ranch, and mid-century stock throughout the Lincoln Park corridor. Our techs know the difference between Classic Max shrinkage and H2Foam Lite dew-point failure without guessing. We’re an independent Icynene service provider, not affiliated with or authorized by Icynene, which means we recommend replacement materials from our full catalog - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, GreenFiber, and Reflectix - based on what the assembly actually needs, not what a single manufacturer sells. The 365-Day Done Right Promise applies to every job, and our before-and-after blower-door numbers are published, not promised.
FAQs
The original Icynene installation warranty was issued to the first owner by the installing contractor and is generally non-transferable; removal by any party terminates what coverage remains. As an independent Icynene service provider, we do not extend manufacturer warranties, but our 365-Day Done Right Promise and written scope document what we stand behind. Call (562) 242-7569 to review your specific situation.
Yes - R-value is a material property, not a brand property. We often replace removed Icynene with cellulose, fiberglass, or a different foam formulation to hit the target R-value while solving the problem that caused the removal. The blower-door test tells us whether air sealing or thermal resistance was the foam’s primary contribution, and we design accordingly.
Most partial removals finish in one day; full attic jobs typically take two days, with a third day if substrate repair is needed. We don’t rush removal - mechanical shaving is slower than grinding but keeps particles contained. Call (562) 242-7569 for availability; a live person answers 24/7.
Spot repair is cheaper only when the failure is isolated, the substrate is sound, and the remaining foam tests intact. In our experience, shrinkage and moisture damage in Pomona’s hot attics spread beyond what’s visible. We price both options when possible, but we won’t patch over a systemic problem. The written scope shows exactly what each approach includes.
We don’t stock Icynene product for resale - we’re a removal and replacement contractor, not a distributor. Replacement materials from our supplier relationships (including Icynene, Demilec, and others) typically arrive within three to five business days. Rush sourcing is available for an added freight charge when the situation demands it.
