Every mold genera has a different outdoor background level in different seasons and regions of Baltimore, MD. Without an outdoor baseline collected the same day from the same property, an indoor spore count is just a number — not a finding. We collect outdoor comparative samples on every job.

A spore count without an outdoor baseline is just a number. Our protocol is designed to make the number mean something.
The sampling method determines what question gets answered. We match method to question — and explain the difference before booking.
