Environmental Relative Moldiness Index testing analyzes dust samples using DNA methods for a broader property-wide picture.
This pairing gives Marshall clients documented proof the job worked, not just a verbal assurance.
We recommend clearance testing be done by a different technician than the one who performed the work, for objectivity.
We'll walk you through what your results actually mean in plain language, not just hand you a page of species names.
