Icynene Insulation Removal & Replacement Nationwide

Icynene Insulation Removal & Replacement in La Puente: What to Know First

We provide independent Icynene insulation removal & replacement in La Puente, typically completing most jobs in a single visit with a written price delivered before any work starts. Most Icynene attic removals in the San Gabriel Valley run between $2,800 and $5,400 depending on contamination level, square footage, and whether the existing foam needs mechanical scraping or can be pulled in sheets. This page is for homeowners who know they’ve got Icynene in their attic - open-cell LC-50 or closed-cell MD-R-200, usually - and need it out because of rodent damage, water intrusion, or a failed initial install that’s trapping moisture against the roof deck.

How Icynene Products Fail - and How We Fix Them

• LC-50 open-cell attic foam oversprayed against roof decks. In La Puente’s combination of hot, dry summers and occasional winter rains, LC-50 sprayed directly to the underside of plywood roof decking without a vent channel can hold moisture at the wood interface. We’ve pulled sections in Valinda where the foam was intact but the deck behind it was punky. Our fix: mechanical removal with specialized foam planers, then installation of proper baffles or a vented assembly before any replacement insulation goes in.
• MD-R-200 closed-cell with inadequate substrate prep. MD-R-200 bonds aggressively when the substrate is clean and dry, but in the tract homes off Hacienda Boulevard built during the 2004-2007 rush, we’ve found it delaminating from dusty OSB or oil-stained framing. The foam itself is fine; the adhesion failed. We remove the detached sections with reciprocating blades and wire brushes, then prep the substrate properly before reinstalling or switching to a different insulation strategy.
• Water staining from condensate lines or roof leaks trapped behind the foam. Icynene’s open-cell products are vapor-permeable, but when they’re sprayed thick enough to act as an air barrier, they can mask the path of a leak until the damage is extensive. We find this in La Puente’s older ranches near Puente Hills, where original galvanized flashing has failed. Our crew cuts away the affected foam in blocks, documents the water damage with photos, repairs the source, then replaces the insulation - never burying a leak.
• Rodent infestation in foam with embedded nesting material. Mice and rats tunnel into open-cell Icynene more readily than dense fiberglass or mineral wool. The urine and feces saturate the foam matrix and create a persistent odor. Standard attic cleaning won’t reach it. We remove the contaminated foam entirely, treat the framing with an enzymatic cleaner, and install new insulation only after the attic passes a clearance test.
• Original install with no air sealing beneath the foam. This isn’t a foam failure, it’s a sequencing failure - and it’s common. A previous contractor sprayed Icynene over unsealed top plates, can lights, and wire penetrations. The foam looks fine, but the house still leaks. We remove or work around the existing foam, seal the leaks with targeted foam and gasketed covers, then replace or supplement the insulation. Seal the leaks first. The insulation is just the last layer, not the fix.

Our Icynene Insulation Removal & Replacement Process

1. 1
   Site assessment and written scope. We inspect the attic, identify the Icynene product line and condition, and photograph everything. You get a written price before any work starts - Haven Standard Clause 1.
2. 2
   Containment and protection. We seal the attic hatch, cover finished surfaces below, and set up negative air if the foam is friable or contaminated. Our crew wears PPE rated for the specific material.
3. 3
   Mechanical removal. Open-cell LC-50 often pulls away in manageable sheets with pry bars and specialized blades. Closed-cell MD-R-200 requires planers, scrapers, and sometimes controlled heat application. We bag all debris per local La Puente disposal requirements.
4. 4
   Substrate repair and air sealing. With the foam gone, we seal top plates, electrical penetrations, can lights, and chimney chases - the work that should have happened first. We document this with photos.
5. 5
   Replacement insulation installation. Depending on your goals and budget, we install new blown cellulose, fiberglass, or a different spray foam system - sourced from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Demilec, or GreenFiber. No proprietary lock-in.
6. 6
   Final documentation and walkthrough. You receive a Documented Photo Record, a written depth log with R-value achieved, and on applicable jobs, before-and-after blower-door numbers showing the actual air-sealing improvement.

What Icynene Insulation Removal & Replacement Costs in La Puente

Most Icynene removal and replacement jobs in La Puente fall in these ranges:

What moves the price: accessibility (steep roof pitch, tight scuttle vs. full staircase), whether the foam is mechanically bonded or delaminated, presence of asbestos-containing vermiculite underneath, and the replacement insulation type selected. We also service Reflectix and other systems if your project involves mixed materials. Every estimate is free, written, and includes no obligation - bring us a competing written quote and we’ll review it with you at no charge.
