Dry Ice Blasting Mold Removal Newark NJ

How Dry Ice Blasting Actually Works

A blasting rig accelerates rice-sized dry ice pellets — solid CO2 at around -109°F — at the moldy surface. On impact, two things happen: the kinetic hit knocks contamination loose, and the pellet instantly sublimates into gas, expanding nearly 800 times and lifting residue out of the wood grain. The CO2 simply dissipates into the air. No water, no chemicals, no blasting media to sweep up afterward.

That's why blasting dominates attic and framing work: it cleans rafters, joists, and sheathing in hours where hand-scrubbing would take days, and it reaches into grain and crevices that wire brushes miss. It's not right for everything — drywall and painted surfaces are usually better handled manually — but on bare wood it's unmatched.

• Sublimation, not abrasion — Pellets vanish into CO2 gas on impact; the cleaning comes from thermal shock plus kinetic energy.
• Zero secondary waste — No sand, no soda, no water to collect — only the dislodged mold debris, HEPA-vacuumed after.
• Gentle on sound wood — Properly calibrated pressure cleans without gouging framing members.
• Reaches the grain — The expanding gas lifts contamination out of wood pores hand tools can't reach.
• Fast on large areas — Whole attics and crawl space framing cleaned in hours, not days.
• Dry process — No moisture added, so there's no drying wait before verification.
• Contained work zones — Blasting generates heavy particulate; we seal and ventilate the area first.
• Licensed and insured — License and insurance details provided on request.
