How Icynene Products Fail - and How We Fix Them

We’ve opened more Icynene attics in West Covina than we can count, and the failure patterns repeat themselves. Here’s what we actually see:

• Icynene Classic Plus (open-cell spray foam) and rodent tunneling. Open-cell foam is soft enough for roof rats and mice to chew through, especially along soffit edges and where the foam meets framing. Once they’re in, they carve runways right through the foam. We remove the contaminated sections, sanitize, and install steel exclusion at entry points before any new foam goes back.
• Icynene ProSeal and air-sealing gaps. ProSeal is a closed-cell product, which handles moisture better, but if the original installer didn’t foam the top plates or can-light boxes, rodents squeeze through gaps smaller than a nickel. We find these gaps with thermal imaging, seal them with proper materials, and re-inspect every penetration.
• Icynene Blown Insulation (loose-fill fiberglass) and contamination. This is the one we see most often in older West Covina homes near the Eastland Center corridor. Rodents nest in the loose fill, soak it with urine, and turn it into a biohazard. We remove all of it with HEPA-filtered vacuums, sanitize the deck, and install fresh material or spray foam depending on what the attic needs.
• Baffle and vent blockages on Icynene attics. When spray foam is applied too aggressively around soffit vents, airflow stops. West Covina summers push attic temps past 130°F, and a blocked vent means a hot attic and a hotter house. We clear and repair baffles, then confirm the venting actually works before we leave.
• Deteriorating sealant around roof penetrations. Over time, the sealant around plumbing stacks and flue pipes dries out and separates from the foam. That’s an open door for rodents and a silent air leak. We scrape, re-seal with fire-rated materials around flues, and verify the foam is intact around the repair.

Our Icynene Attic Cleaning & Rodent Proofing Process

1. 1
   Call and talk to a person. You call (626) 612-1532. We answer live, ask about the symptoms, and schedule a visit. No call center, no voicemail.
2. 2
   Attic inspection. A background-checked, uniformed tech walks the attic with a flashlight and a camera. We document what we find: rodent entry points, damaged Icynene foam, contaminated insulation, duct damage.
3. 3
   Straightforward quote, before any work. We give you a written number and explain exactly what’s included. No vague line items, no surprise fees. Free second opinion on any written estimate.
4. 4
   Removal and sanitizing. We remove contaminated material, vacuum with HEPA filtration, and apply an antimicrobial treatment to the decking and framing. This kills the bacteria that cause odor and health issues.
5. 5
   Exclusion and proofing. We seal entry points with steel mesh, hardware cloth, and foam rated for pest resistance. Gaps at vents, eaves, gables, and plumbing penetrations get addressed one by one.
6. 6
   Final check and the Done Right Promise. We verify the attic is clean, sealed, and dry before we call the job done. Every job is backed by our lifetime workmanship guarantee. If it’s not done right, we make it right.
