Icynene Insulation Removal & Replacement in Mountain View: What to Know First
We provide independent Icynene insulation removal and replacement in Mountain View, 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 the area run between $3.80 and $5.20 per board foot, depending on accessibility and whether the foam has degraded or been compromised by moisture. This page is for homeowners who found Icynene spray foam in their attic, walls, or crawl space and need it safely extracted and replaced with a properly air-sealed, high-performing system.

How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell, 3.5 lb density) - shrinkage and pull-away from framing. In Mountain View’s dry summer heat, Classic Max can contract 5-10% from original volume over 8-12 years, creating gaps at stud bays and top plates. We remove the detached foam mechanically, then air-seal every joint with closed-cell foam at the rim joist and transition zones before installing replacement insulation.
- Icynene MD-R-200 (medium-density closed-cell) - moisture trapping behind impermeable skin. When MD-R-200 is applied too thick in a single pass, the exothermic reaction traps solvent vapor that later condenses against sheathing. We find this most often in Rex Manor and Old Mountain View homes with original 2012-2016 installations. Our fix: full removal, moisture meter readings on every rafter, then staged replacement with vapor-smart layering.
- Icynene LD-C-50 (low-density open-cell) - rodent nesting and biological loading. The semi-rigid structure of LD-C-50 makes attractive tunneling for roof rats, which are persistent in Mountain View’s tree-canopied neighborhoods. We extract contaminated sections, apply enzyme treatment to substrates, and replace with borate-treated cellulose or sealed closed-cell systems that rodents won’t occupy.
- Icynene H2Foam Lite (water-blown open-cell) - off-gassing and odor persistence. Improper catalyst mixing during original application leaves residual amines that off-gas for years, especially in warm attics. We remove the full lift, ventilate the cavity for 48 hours with forced air, then verify air quality before installing replacement material.
- Icynene Classic Plus (hybrid open-cell with vapor retarder coating) - coating delamination. The acrylic vapor retarder applied to Classic Plus peels where attic temperatures cycle above 140°F, common in Mountain View’s south-facing roofs. We strip foam and failed coating together, then specify replacement insulation appropriate to the actual vapor drive of the assembly.
Our Icynene Insulation Removal & Replacement Process
- 1
Site assessment and blower-door baseline. We pressurize the house to measure CFM50 - the starting leak rate - and photograph every Icynene-located cavity. You get both before any quote is written.
- 2
Written price and scope under Haven Standard Clause 1. Flat price, written warranty, documented photo record included. No work starts without your signature on the scope.
- 3
Controlled removal with HEPA containment. Icynene foam is removed mechanically or chemically softened depending on density and substrate. We isolate the work zone with negative air pressure; this is not a DIY procedure.
- 4
Substrate drying and air sealing. Every top plate, can light, and penetration at the attic floor is sealed before replacement insulation goes in. Seal the leaks first. The insulation has nowhere to go if the air does.
- 5
Replacement installation and blower-door verification. We retest after sealing and again after insulation. The two readings go in your written report, along with ACH50 - air changes per hour at 50 pascals.
- 6
Cleanup, photo record delivery, and 365-Day Done Right Promise activation. You walk away with before-and-after images, blower-door printouts, and a single point of contact if anything needs attention.
What Icynene Insulation Removal & Replacement Costs in Mountain View
| Scenario | Typical Range | What Moves Price |
|---|---|---|
| Partial Icynene removal (contaminated section, up to 200 sq ft) | $1,800 - $3,400 | Height of attic, presence of HVAC ducting, rodent soiling depth |
| Full attic Icynene extraction (1,200-1,800 sq ft) | $4,500 - $7,200 | Density of original foam, sheathing condition, need for substrate repair |
| Icynene removal + closed-cell replacement (R-21 walls) | $6,800 - $10,500 | Cavity depth, number of penetrations to seal, finish repair scope |
| Icynene removal + blown-in cellulose (attic, R-38 to R-49) | $3,200 - $5,800 | Prep and air sealing extent, baffle installation, access hatch upgrade |
These ranges reflect Mountain View’s current labor and disposal costs, including Icynene’s classification as a polyurethane waste stream requiring specialized handling. The only way to get your exact price is a site visit, which is free and produces a written, locked quote before any work starts.

Wes Okafor sequences every job the same way he learned on the Peninsula: air seal first, insulate second, document everything. Our crews are background-checked and uniformed; the phone is answered by a live person, 24/7. We also service Reflectix and other radiant barrier systems when the assembly calls for hybrid solutions. The 365-Day Done Right Promise applies to every Icynene removal we complete, backed by a written scope and warranty delivered before anyone lifts a tool. Nine thousand homes sealed and insulated since we started, every one with a written price first and a documented record at the end.
FAQs
The original Icynene installation warranty is void once the foam is altered or removed, which is why we operate as an independent Icynene service provider with our own 365-Day Done Right Promise on replacement work. Our warranty covers the removal, substrate preparation, and new installation - call (669) 259-0406 and we’ll show you the written terms before any work starts.
Yes, and often improve it. Icynene Classic Max at 3.5 inches delivers about R-13; we routinely spec R-15 dense-pack cellulose or R-21 closed-cell foam in the same cavity depth, with better air-sealing performance documented on the blower-door test. Your written scope will list the target R-value and the material we plan to use.
Most residential attic jobs in Mountain View take one to two days for removal, plus a third day for drying, air sealing, and replacement installation. Larger homes in the Monta Loma area or jobs with multiple foam densities may run to four days. We give you a day-by-day schedule in the written scope.
No, and we won’t do it. Compromised Icynene - shrunken, moisture-loaded, or rodent-nested - traps humidity against sheathing and masks air leaks that new insulation will bury. The correct sequence is removal, substrate verification, air sealing, then replacement. Anything else wastes your money and violates the Haven Standard.
We typically schedule Icynene assessments within 48 hours in Mountain View, with removal crews available within a week depending on containment setup requirements. Call (669) 259-0406 - a live person answers, and you’ll get a text when your technician is on the way.
