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

About
How wall cavity mold testing works
Our certified mold inspectors create a small access point in a discreet location, then thread sampling equipment through to reach inside. Air sampling and swab sampling collect material from within, sealed and sent to a state-certified lab.
Our process includes:
- —Identifying suspect wall sections through moisture readings
- —Minimally invasive access at the chosen sample point
- —Air or swab sampling from within the wall structure
- —Lab-verified results identifying mold species in a mold inspection report
