This page is for Cedar Park homeowners who installed Icynene open-cell or closed-cell foam and now face rodent damage, soiled insulation, or compromised attic conditions that require cleaning and re-sealing. We are an independent Icynene service provider, not affiliated with or authorized by Icynene, and we work on Icynene LD-C-50, MD-C-200, and other common lines found in Cedar Park homes built between 2015 and 2023. Wes Okafor brought blower-door discipline from Chicago’s building science program to Central Texas, and our crew has handled Icynene retrofits across Cedar Park including the Buttercup Creek subdivision where summer attic temperatures hit 140°F and accelerate foam degradation.

How Icynene Products Fail - and How We Fix Them

• LD-C-50 open-cell sagging in Cedar Park’s heat. This entry-level open-cell foam can pull away from roof decks when attic temperatures sustain 130°F-plus for weeks each summer, which is standard in Cedar Park from June through September. The gap creates a thermal bypass and collects rodent nesting material. We remove the compromised sections, clean the substrate, and reapply only after verifying the roof deck ventilation path with a smoke pencil. We document the before-and-after gap dimensions in your photo record.
• MD-C-200 closed-cell odor retention after rodent infestation. The higher density of this medium-density closed-cell line traps urine and organic matter in the foam matrix where surface cleaning cannot reach it. Homeowners in Cedar Park’s Ranch at Brushy Creek and Shenandoah subdivisions have called us when the HVAC return pulls attic odor through recessed can-light penetrations. We excise the contaminated foam to solid substrate, apply enzymatic decontamination, and replace with new MD-C-200 or discuss alternatives if the original application was substandard thickness.
• Classic Series shrinkage at top plates and electrical penetrations. Early Icynene Classic installations in Cedar Park sometimes experienced 2-5% linear shrinkage as the foam cured against hot OSB in unvented attics. The resulting cracks at top plates and wire holes become rodent highways. We don’t caulk over shrinkage cracks; we cut back to sound foam, clean the cavity, and refoam with proper lift thickness to prevent recurrence. Your written scope specifies the lift depth and cure time before we close.
• Water staining on Icynene from roof leaks that went undetected. Foam’s water resistance is a benefit until it hides a slow roof leak for two years. By the time Cedar Park homeowners see ceiling staining, the Icynene has wicked moisture deep into the assembly and mold has colonized the back side. We remove the affected foam in controlled sections, inspect the roof deck with moisture meters, document the readings, and coordinate with your roofer if the leak source is still active. The photo record includes moisture meter readings at 12-inch intervals.
• Retrofit compatibility: Icynene over existing fiberglass in older Cedar Park homes. Some 1980s and 1990s homes in Cedar Park’s original neighborhoods received Icynene spray foam over existing fiberglass batts without proper cleaning or air sealing first. The trapped fiberglass compresses, rodents nest in the void, and the assembly performs worse than either material alone. We remove the entire hybrid assembly down to the drywall, clean and sanitize, seal all top plates and penetrations with blower-door guidance, then reinstall correctly. Seal the leaks first. Then insulate. The order matters more than the product.

Our Icynene Attic Cleaning & Rodent Proofing Process

1. 1
   Pre-work blower-door test and written price. We pressurize the house to measure ACH50 - the air changes per hour at 50 Pascals pressure - and identify where your envelope leaks. You get the written scope, the price, and the warranty before anyone enters the attic. No exceptions.
2. 2
   Contamination assessment and documentation. We photograph every Icynene surface, mark rodent entry points with GPS-tagged locations, and test foam density with a core sampler to confirm which Icynene line was originally installed. This determines whether OEM-spec replacement foam or compatible aftermarket product is appropriate.
3. 3
   Controlled removal and HEPA-contained cleaning. We section the attic with plastic isolation barriers, run negative air machines, and remove contaminated Icynene with specialized cutting tools that don’t tear adjacent sound foam. All debris is bagged in the attic, never dragged through living space.
4. 4
   Substrate decontamination and rodent exclusion. We apply enzymatic treatment to wood surfaces, seal all penetrations with copper mesh and foam compatible with your existing Icynene chemistry, and install rigid metal flashing at known rodent access points. Every sealed point is photographed.
5. 5
   Replacement, post-work blower-door test, and photo record delivery. We reinstall Icynene or discuss alternatives if your original application was flawed. The post-work blower-door test shows your new ACH50 number. You receive the documented photo record, both blower-door readings, and the 365-Day Done Right Promise in writing before we leave.

What Icynene Attic Cleaning & Rodent Proofing Costs in Cedar Park

Three factors move the price: how much Icynene must be removed versus cleaned in place, whether rodent exclusion requires roofline work or just interior sealing, and if the original foam was applied below manufacturer thickness and needs full replacement to perform. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly. Every estimate is free, written, and binding - no open-ended allowances. Call (737) 245-6428.
