This page is for Thousand Oaks homeowners who already have Icynene insulation, or are considering it, and want straight answers about how blown in insulation works with it. No manufacturer jargon. No surprise pricing. Just what we’ve learned after years in attics across Thousand Oaks.
How Icynene Products Fail – and How We Fix Them
Icynene makes open-cell and closed-cell spray foam, but plenty of Thousand Oaks homes have a hybrid setup: Icynene foam in the roofline or walls, with blown in insulation on the attic floor. Here are the failure modes we see most often, and what we actually do about them.
- Icynene Classic Plus shrinkage around penetrations. This open-cell foam can pull back slightly from can lights, vent pipes, and framing over time. That gap lets conditioned air escape and draws dust into the foam. We re-seal those gaps before adding blown in insulation, because blowing fiber on top of a leaky air seal just buries the problem.
- Icynene ProSeal uneven application. This closed-cell line is sprayed, and we sometimes find thin spots where the installer moved too fast, especially along hip roofs and dormers in older Thousand Oaks ranch homes. The fix is spot-foaming the thin areas, then balancing the attic floor with blown in insulation to hit a consistent R-value across the whole ceiling plane.
- Moisture trapped between Icynene foam and roofing deck. Thousand Oaks gets the marine layer pushing in from the coast and hot inland afternoons, which creates condensation cycles. If bathroom fans or dryer vents were routed into the attic instead of outside, moisture collects against the foam. We identify the source first, correct the venting, then address any compromised insulation.
- Open-cell Icynene absorbing dust and attic debris. Open-cell foam has a sponge-like texture. Over years, dust from Thousand Oaks wind events and Santa Ana conditions settles into the top layer of the foam and reduces its air-sealing performance at the surface. We don’t replace it for that. We stabilize what’s there and add blown in insulation to restore thermal performance without disturbing the foam.
- Improperly installed Icynene in vented attics. This is common. A previous contractor sprayed Icynene on the attic floor in a vented attic, which traps heat between the foam and the ceiling drywall. The correct approach in a vented attic is blown in insulation on the floor with proper airflow from soffit to ridge vents. We remove failed floor foam, restore the ventilation path, and blow in fresh insulation.

What Icynene Blown In Insulation Costs in Thousand Oaks
Straight numbers, because you shouldn’t have to guess. Blown in insulation over existing Icynene in a typical Thousand Oaks attic runs from $1,800 to $2,800 for fiberglass and $2,200 to $3,400 for cellulose. If we need to remove failed Icynene foam from an attic floor first, add $1,500 to $3,000 depending on depth and accessibility. Spot foam repairs to Icynene ProSeal or Classic Plus run $350 to $850 per area.

FAQs
In most cases, no. Icynene warranties cover the foam product itself, not what you add on top of it. That said, we’re an independent Icynene service provider, not a manufacturer-authorized contractor, so we recommend checking your specific warranty document. We’ll work in a way that respects the existing foam and doesn’t compromise what’s already in place. Call (805) 309-1610 and we’ll walk through your setup.
Yes, if the Icynene is on the roofline or walls and the attic floor is bare or under-insulated, blown in insulation goes right on the floor. If the Icynene was sprayed on the attic floor itself in a vented attic, it usually needs to come out first so the attic can breathe the way it was designed to. We’ll tell you which situation you have during the inspection.
Most Icynene blown in insulation jobs in Thousand Oaks are scheduled within 24 to 48 hours. If your attic has exposed wiring or moisture issues causing active damage, we can often prioritize same-day assessment. Call (805) 309-1610 and a live person will get you on the schedule.
Repairing is almost always cheaper when the foam is structurally sound.
