Every mold genera has a different outdoor background level in different seasons and regions of Mount Rainier, 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.
