Dry ice blasting uses solid CO2 pellets accelerated at high velocity to lift mold from wood, concrete and drywall in Mentone properties. The process leaves no residue because the pellets sublimate on contact, which matters in older homes near Zanja Creek where moisture from cool winters often hides behind baseboards and in crawl spaces. Technicians control blast pressure and angle to avoid damaging plaster or framing common in San Bernardino County houses built before modern vapor barriers.
Hot dry summers in Mentone drive homeowners to run evaporative coolers that can push spores deeper into wall cavities. Dry ice blasting reaches those areas without the water introduction that liquid cleaning methods risk. Crews seal off Mentone Park-adjacent neighborhoods during work to prevent cross-contamination into nearby Redlands and Yucaipa homes that share similar soil and drainage patterns.
Edge cases include attics with blown-in insulation where pellets can dislodge material if pressure is not dialed down, and exterior stucco homes where thermal shock from the cold pellets must be managed to prevent cracking. Local code requires containment and HEPA filtration on every job; skipping either step violates San Bernardino County air-quality rules and can spread spores into Calimesa properties downwind.
After blasting, surfaces are vacuumed with HEPA equipment and treated with an antimicrobial that meets current California guidelines. Homeowners receive a written report noting moisture readings at Zanja Creek-influenced lots where groundwater can reintroduce conditions within one season if grading is not corrected.
Technician insight
In Mentone, the thing that catches most people out with dry ice blasting mold is how cool winter air from Zanja Creek keeps soil moisture high around older slab foundations near Mentone Park, letting spores survive in the subfloor even after visible growth is gone.
Attic Mold Near Zanja Creek
A Mentone homeowner noticed musty odors after the first cool spell. Inspection found hidden mold on roof sheathing above the garage where summer evaporative cooler use had pushed moisture. Dry ice blasting removed the growth without tearing out insulation. Post-treatment readings stayed below county limits and the odor did not return the following winter.
How it works
- 1
Initial Containment
Technicians seal the work zone with plastic sheeting and negative air machines to protect adjacent rooms in Mentone homes.
- 2
Dry Ice Blasting
Pellets are blasted at controlled pressure to remove mold from framing, concrete and drywall without water or harsh chemicals.
- 3
HEPA Vacuum and Antimicrobial Application
All loosened material is vacuumed and surfaces receive an approved antimicrobial treatment.
- 4
Final Moisture and Air Testing
Readings confirm levels meet county standards before containment is removed.
