Dry ice blasting removes mold growth and staining from joists, subfloor sheathing, band boards, studs, and roof decking without adding a drop of water to an assembly that is already fighting humidity.
Serving Mecklenburg, Union, Cabarrus, Gaston, Iredell counties and nearby Concord, Gastonia, Rock Hill along the I-85 / I-77 interchange.
Humid subtropical with summer dew points in the low 70s and mild, damp winters. Crawlspaces stay near dew point most of the cooling season, so condensation — not plumbing leaks — drives most mold calls in Mecklenburg County.
Pin and pinless moisture readings on framing plus a look at the actual driver — condensation, ground moisture, plumbing, or storm intrusion. Cleaning without the cause fixed is a repeat call.
Poly containment, HEPA negative air machines, and CO2 monitoring in the work zone. Occupied areas of the building stay isolated from the blast media stream.
Media is driven at documented pressures so growth and staining lift out of the wood grain and truss crevices that sanding and wire wheels physically cannot reach.
Surfaces and horizontal collection areas are HEPA vacuumed, then photographed and documented for third-party clearance testing.
Work is scoped to the IICRC S520 principle of physical source removal — the growth comes off the substrate rather than being encapsulated or killed in place — with containment, negative air, and HEPA filtration through the whole blast window.
Dry ice blasting removes staining and spore load from joists, subfloor sheathing, and band boards in one dry pass, then the encapsulation and dehumidification plan keeps clearance results holding through a Charlotte summer.
Acidic soot on exposed steel, ductwork, and framing is lifted without rinse water, so adjacent occupied units are not exposed to runoff or extended drying.
Conveyors, molds, and tooling are cleaned hot and in place across the I-85 corridor, cutting changeover and cool-down time out of the maintenance window.
We do not make a kill claim. Dry ice blasting physically removes mold growth and staining from the substrate, which is what the remediation standard actually asks for. Any antimicrobial application is a separate, optional step after source removal.
Pressure is set per substrate and validated on a test panel before full-scale work. Dry ice is softer than sand or soda, so structural framing, heart pine, and soft historic brick clean without the substrate loss abrasive media causes.
Most single-family crawlspaces are a one- to two-day blast window depending on square footage, joist depth, and access. There is no dry-down period afterward, so the encapsulation or dehumidification trade can follow immediately.
