How Demilec Products Fail - and How We Fix Them

• Demilec Heatlok Soya HFO overspray on attic decking - the bio-based content in this series can attract rodents seeking residual organic oils, especially in Laguna Niguel’s warm, dry attic environments where food sources are scarce. We remove contaminated overspray mechanically, then apply a borate-based sanitizer that neutralizes scent markers without degrading the foam chemistry.
• Demilec Sealection 500 open-cell degradation near roof penetrations - this low-density open-cell foam can absorb moisture vapor if the vapor retarder is compromised, creating a cellulose-like substrate that rodents will nest in. We cut back degraded sections to sound foam, install a proper vapor retarder, then restore the thermal and air barrier with compatible material.
• Demilec Heatlok XT closed-cell delamination from substrate - the high R-value per inch is excellent until rodents tunnel behind it, separating the foam from roof decking or top plates. We remove delaminated sections, re-secure with mechanical fasteners plus compatible adhesive, and rodent-proof the access path with 26-gauge steel flashing.
• Demilec Froth-Pak sealant gaps around attic hatches and chases - this two-component kit foam shrinks slightly over time in Laguna Niguel’s temperature swings, leaving hairline gaps that mice exploit. We remove old Froth-Pak, install rigid blocking with fire-rated sealant, then verify with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing.
• Demilec recycled-content blown-in settling in irregular cavities - the GreenFiber-blended product line settles 15 to 20 percent in the first two years, creating thermal bypasses that rodents use as highways. We extract settled material, air-seal every top plate and penetration first, then reinstall to specified depth with depth markers at twelve points across the attic floor.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Written price and scope before arrival. We review your Demilec product type, attic layout, and contamination level, then deliver a flat price with written warranty before anyone schedules. No work starts without it.
2. 2
   Blower-door test and thermal imaging on day one. We pressurize the house to 50 pascals, record the CFM50 reading, and photograph thermal anomalies. This baseline tells us whether the Demilec insulation is performing or merely occupying space.
3. 3
   Contamination removal with HEPA containment. All Demilec material with rodent soiling, nesting, or urine saturation is removed under negative air pressure. We bag it, weigh it, and document the volume on your photo record.
4. 4
   Structural repair and rodent exclusion. We seal every penetration larger than one-quarter inch with steel mesh, concrete, or copper wool - materials rodents cannot chew. Demilec-specific gaps at foam-to-substrate interfaces get 26-gauge flashing and fire-rated sealant.
5. 5
   Air sealing before any replacement insulation. Seal the holes first. Then insulate. The order isn’t optional. Every top plate, can light, wire penetration, and chimney chase gets sealed and verified with a post-work blower-door test.
6. 6
   Documentation and 365-Day Done Right Promise. You receive printed pre- and post-test ACH50 numbers, thermal images, installed depth measurements at twelve points, and a written warranty before we load the truck.
