Swab Testing

Mold swab testing handles the textured, damp, and irregular surfaces where mold often grows without any visible sign.

Overview

Why mold swab testing matters

Mold grows in damp areas without always showing on the surface. Swab testing detects microbial growth on materials that are soft, porous, or moisture-prone, and is the right approach after water damage or in spaces that resist visual inspection.

Mold swab testing detects:

  • —Hidden mold on porous or textured materials
  • —Growth in damp spots like under sinks or around HVAC
  • —Contamination on organic materials including wood and fabric
  • —Mold that visual inspection alone tends to miss
