Icynene Attic Cleaning & Rodent Proofing Nationwide

Icynene Attic Cleaning & Rodent Proofing in Campbell: What to Know First

We provide independent Icynene attic cleaning & rodent proofing in Campbell, typically completing most jobs same-day or next-day with a written price before any work starts. Most Campbell homeowners with Icynene spray foam systems pay between $2,800 and $6,400 for full attic cleaning, sanitizing, and rodent exclusion, depending on foam condition and infestation severity. As an independent Icynene service provider, we’re not affiliated with or authorized by Icynene - we service the product based on hands-on field experience, not factory directives.

Call (831) 534-3206

This page is for Campbell homeowners who found droppings in their attic, noticed a smell, or had a pest company tell them their Icynene foam needs attention after rodent activity. If that’s you, call us at (831) 534-3206. We’ll read your situation with you and give you a written price before anyone lifts a tool.

How Icynene Products Fail - and How We Fix Them

• Icynene Classic Max (open-cell) - moisture trapping behind compressed foam. Classic Max is hydrophilic by design, meaning it holds water rather than shedding it. In Campbell’s Mediterranean climate, where winter rains hit roof assemblies that summer sun baked to 140°F, rodent tunneling through Classic Max creates channels where condensation collects against the roof deck. We’ve pulled out sections near the Winchester Boulevard corridor where the foam had turned to a dense, gray sponge, hiding rot from the homeowner for two seasons. We remove the saturated foam, treat the deck with antimicrobial, and reinstall only after verifying the roof leak source is fixed.
• Icynene MD-R-200 (medium-density closed-cell) - rodent gnaw-through at penetration points. MD-R-200 cures to a rigid shell that rodents can’t easily tunnel through, but they exploit the edges where it meets electrical conduit and vent stacks. The gap forms because closed-cell foam shrinks roughly 2-3% during cure, and Campbell’s older stock - particularly the Eichler-influenced homes near San Tomas Aquino Creek - has irregular framing that exaggerates the problem. We cut back the compromised foam, install steel mesh exclusion barriers, and re-foam with matching density so the thermal boundary stays continuous.
• Icynene LD-C-50 (low-density open-cell) - dust and allergen retention in degraded surface layer. After five to seven years, the top surface of LD-C-50 oxidizes to a friable crust that traps rodent dander, urine salts, and airborne particulates. Homeowners near the Pruneyard Plaza corridor have called us thinking they needed new HVAC filters when the real source was their attic foam. We HEPA-vacuum the degraded layer, apply a non-toxic enzymatic treatment, and seal the surface with a vapor-permeable coating so the foam can still breathe.
• Icynene ProSeal Eco (water-blown closed-cell) - delamination from substrate in high-heat attics. ProSeal Eco adheres well to wood, but Campbell’s south-facing roofs with dark shingles create sustained attic temperatures above 160°F. Combined with rodent urine’s ammonia compounds, the adhesive bond fails in patches. We’ve found this most often in the older ranch homes east of Bascom Avenue. We scrape the delaminated sections, re-prep the substrate with primer, and reapply - but we also recommend ridge vent augmentation because the thermal load is the root cause.
• Icynene H2Foam Lite - structural compromise from nesting activity. H2Foam Lite has excellent R-value per inch but lower compressive strength than medium-density alternatives. Roof rats, which are endemic to Santa Clara County, compress it significantly when building nests, reducing thermal performance by 30-40% in affected bays. We map the compromised areas with thermal imaging, remove and dispose of the contaminated foam, and replace with H2Foam Lite or upgrade to MD-R-200 if the homeowner wants better rodent resistance - we explain the trade-off in writing before deciding.

Our Icynene Attic Cleaning & Rodent Proofing Process

1. 1
   Site survey and thermal imaging. We walk the attic with a FLIR camera to map foam condition, moisture anomalies, and rodent pathways. You get a Documented Photo Record before we touch anything.
2. 2
   Written price and scope. We specify which Icynene line you have, what we’re removing, what we’re treating, and what we’re reinstalling. No work starts without your signature on a fixed price.
3. 3
   Controlled removal and HEPA containment. We section out contaminated foam with dedicated cutting tools, never grinding it airborne. Debris is bagged in the attic, not dragged through your living space.
4. 4
   Substrate treatment and exclusion install. We treat wood surfaces for urine and pathogens, then install steel mesh at all penetrations - plumbing, electrical, HVAC - before any new foam goes in. Seal the leaks first. The insulation has nowhere useful to go until you do.
5. 5
   Reinstallation and verification. We match the original Icynene density and thickness, then run a blower-door test - a pressurization measurement that shows, in one number, how much air your building envelope is losing - to verify we didn’t compromise the air barrier during removal.
6. 6
   Documentation delivery. You receive the photo record, blower-door before-and-after readings, and a written warranty under our 365-Day Done Right Promise.

What Icynene Attic Cleaning & Rodent Proofing Costs in Campbell

Price movers: square footage of affected foam, accessibility (Campbell’s low-slope ranch attics are easier than steep Victorian pitches), whether the roof deck needs repair, and how many exclusion points we need to seal. We also service Reflectix radiant barrier systems if your attic has hybrid insulation - we’ll note that in the scope and price it separately if needed.

Our technicians are background-checked and uniformed; calls are answered by a live person, 24/7, not a voicemail loop measured in business days.

We don’t lock you into proprietary products. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - we specify what fits your assembly, not what moves our inventory. Every job closes with a Documented Photo Record and, on applicable work, printed blower-door numbers showing the performance change you paid for. The 365-Day Done Right Promise applies to all completed work: if it’s not done right, we make it right.
