We are doing our part to help “flatten the curve” and limit the potential exposure to the COVID-19 by implementing the following protocol:

Our State Certified Technicians will be wearing protective gloves and mask. All of our field equipment, coolers and vehicles are constantly being wiped down with a disinfectant solution as well as any work surface in our laboratory and office.

All inspections will be conducted outside, unless the house is unoccupied.

We ask if buyers, sellers, and/or agents are present during the inspection to please wear a protective mask and keep a minimum of 6 ft social distance from our technicians.

Office and laboratory doors are locked.  Ice coolers are provided on the front steps. Please fill our chain of custody form and submit with samples. Call office prior to drop off.
