How Icynene Products Fail - and How We Fix Them

Icynene open-cell and closed-cell foams behave differently in attics, and each has its own weak points we see across Inglewood. Here’s what actually goes wrong:

• Icynene Classic (open-cell) shrinkage at top plates. Open-cell foam can pull back from framing as it cures, especially in attics that bake under Inglewood’s summer heat. That leaves a hairline gap along every top plate - small enough to ignore, big enough to leak conditioned air. We trace the perimeter, clean the joint, and seal with a compatible foam or caulk that flexes with the framing.
• Icynene ProSeal (closed-cell) can-light gaps. Closed-cell doesn’t shrink much, but recessed can lights were often skipped during the original spray because of fire-rating concerns. That leaves a hot, leaky ring around each fixture. We install proper covers or seal from below with the right material, keeping clear of the housing so you don’t create a fire hazard.
• Icynene Classic Low-Density around duct boots. Duct boots are notorious for pulling loose as homes settle. Where the boot meets the drywall, we often find daylight showing through. We seal the boot-to-drywall seam and the duct-to-boot connection, because air leaking into the attic from either joint means your HVAC is paying to condition the roof.
• Attic hatch leakage - the one nobody thinks about. Your Icynene could be perfectly installed and your attic still leaks if the pull-down hatch or access door isn’t gasketed. We add weatherstripping, insulation board to the hatch itself, and latch tension so it actually closes tight against the frame.
• Incomplete coverage around plumbing and electrical penetrations. We regularly find stacks, wires, and bathroom fan vents that were sprayed around but never fully sealed, especially in older Inglewood homes where these were added after the original foam. We seal each penetration at the drywall plane, not just the attic floor, which stops the stack effect in both directions.

Our Icynene Attic Air Sealing Process

Here’s exactly how a typical Icynene attic air sealing job goes from first call to final walkthrough:

1. 1
   You call, a live person answers. We ask about your home’s age, when the Icynene was installed, and what symptoms you’re seeing - hot upstairs rooms, high bills, dust, drafts. We book a time that works.
2. 2
   Diagnostic walkthrough. Neil Ashford or one of our trained techs inspects the attic floor, top plates, penetrations, can lights, duct boots, and hatch. We photograph what we find and show you before sealing anything.
3. 3
   Parts and material decision. We use Icynene-compatible sealants and, where replacement foam is needed, quality materials that bond correctly with your existing foam. We never upsell you to a brand swap if your Icynene is still doing its job.
4. 4
   The sealing work. Most jobs are completed in a single visit. We work methodically, seal every identified leak, and clean up after ourselves - no foam drips left on your garage floor.
5. 5
   Verification. We re-check each sealed location, test the hatch, and run through the work with you before we leave.
6. 6
   The 90-Day Done Right Promise kicks in. If anything we sealed isn’t right, we come back and make it right. That’s a written commitment, not a handshake.

What Icynene Attic Air Sealing Costs in Inglewood

• Full attic floor air sealing, including penetrations and duct boots: $850-$2,400 depending on attic condition and access
