The problem this solves
Surface mold on exposed framing, joists, subfloor decking, and structural steel needs to come off the substrate without introducing more moisture into the structure. Wet methods are usually disqualified; dry methods are typically slow.
The honesty point: mold remediation is a containment-and-moisture-control project before it's a cleaning project. The blast scope is necessary but not sufficient — the IEP scopes the work, the remediator owns containment and clearance, and the GC fixes the moisture source.
Why dry ice blasting fits
Dry ice removes surface mold colonies and the underlying soil without adding water to the structure. The substrate dries faster because it wasn't wet to begin with. The contaminant captures into the containment vacuum and ships out per the remediator's protocol.
The blast pass is what makes the eventual clearance test cleaner. It's not a substitute for the IEP-scoped work and clearance protocol — it's the mechanical step that lets the protocol close out.
Surfaces and equipment we clean
- Exposed framing and joists
- Subfloor decking
- Open-web steel and trusses
- Crawlspace ceilings and band joists
- Attic rafters and sheathing
Where this isn't the right method
- Drywall and porous board with embedded growth — that's removal-and-replace, not blasting.
- Active water source — fix the moisture source before blasting starts.
How the engagement runs
- 01Scope with the remediator + IEP
We work to the IEP-scoped work plan. Our role is the blast step, not the containment or clearance.
- 02Containment integration
We blast inside the remediator's containment with HEPA capture coordinated to their vacuum strategy.
- 03Per-zone documentation
Timestamped photos by containment zone — for the remediator's clearance package.
- 04Handoff for clearance
The remediator runs clearance. We don't gate that process.
What drives the quote
- Square footage in scope
- Containment integration complexity
- Documentation depth
- Number of containment zones
What we bring, what we coordinate
- Respiratory PPE per IEP-scoped contamination class.
- CO₂ monitoring inside containment.
- Coordinated with the remediator's air-scrubber + negative-pressure setup.
Mold Remediation Prep — questions buyers ask us
No. We're the blast subcontractor. The remediator owns containment, IEP coordination, and clearance.
We remove the colony from the substrate mechanically. Killing is a separate question — dry ice on its own isn't a biocide. The remediator's protocol handles that step.
No. Containment is about airborne spore control, not water. Containment stays.
