Wall Cavity Mold Testing

Most mold problems start inside the wall, not on its surface. We confirm what's growing before any demolition.

Overview

Why wall cavity mold testing matters

Leaking pipes, condensation building on cold walls, and past water intrusion all leave moisture stuck inside wall cavities, where mold grows for months without anyone noticing. A standard visual inspection misses this completely. Wall cavity mold testing uses small access points, typically about the diameter of a drill bit, to pull air or surface samples from within the wall structure. The result confirms whether growth is present and identifies the species, before any demolition gets approved.

Wall cavity mold testing detects:

  • —Active mold growing hidden inside drywall or plaster
  • —Elevated spore counts from past water damage
  • —Hidden growth around plumbing runs and exterior walls
  • —Mold in walls that smell musty but show no visible staining
