At PurEstate, we believe mold remediation should focus on physical removal of contamination, not simply killing, staining, encapsulating, or masking it. Dry ice blasting is one of the most effective methods available for cleaning mold-contaminated structural wood while preserving salvageable building materials.

Dry ice blasting uses compressed air to propel solid carbon dioxide (CO₂) pellets (rice) at high velocity at contaminated surfaces. Upon impact, the dry ice sublimates directly from a solid to a gas, lifting mold growth, fungal staining, and embedded contamination from the surface of the wood without introducing moisture or chemical residues. The process produces minimal secondary waste because the dry ice dissipates on contact, leaving only a small amount of sawdust and the removed contamination.

Remove Mold From Wood

Why We Use Dry Ice Blasting

Dry ice blasting allows us to:

  • Physically remove mold contamination from structural lumber.

  • Clean irregular surfaces, cracks, nail penetrations, and wood grain.

  • Avoid introducing additional moisture into already damaged building materials.

  • Optimize labor by doing large areas with fewer employees required

  • Reduce secondary waste compared to many other traditional media blasting methods.

  • Actually REMOVE MOLD

Where Dry Ice Blasting Works Best

Not every situation requires dry ice blasting, and not every mold-contaminated material can be saved. When structural materials have experienced deterioration, decay, or loss of integrity, removal and replacement may still be necessary.

Part of a Complete Remediation Process

We don’t stop there. After blasting, we follow that up with our typical small-particle cleaning. HEPA vacuum the dust and particulate left behind. Followed by a damp wipe and dry wipe. Effectively removing all of the contaminants.

A Better Option for Sensitive Clients

Many homeowners come to PurEstate after experiencing unsuccessful remediation projects that relied heavily on chemicals, fogging agents, or encapsulation coatings. Because dry ice blasting relies on mechanical removal rather than chemical treatment, it aligns with our philosophy of reducing unnecessary chemical exposure while focusing on source removal.

Dry ice blasting is perfect for a renovation or a down-to-the-studs remodel. We are limited by the host length, so this is not always a viable option in crawl spaces and attics unfortunately.
