01
Agree on the sampling plan
Tell us why you are testing and who needs the results. For a purchase, rental concern or completed cleanup, share any written requirements and deadline before the visit. We agree on the locations, sample count and deliverables.
02
Prepare without changing the evidence
Ask for preparation instructions when booking. Share recent cleaning, open-window use, HVAC operation, air purifiers and ongoing building work. Avoid changing those conditions just to influence a result; record any necessary changes with the technician.
03
Collect and record samples
The pump draws a measured air volume through the selected collection media using the applicable method. We record sample identification, location and relevant site conditions. Flow and duration follow the method rather than a single time used for every property.
04
Laboratory analysis
Samples are labeled and submitted with collection records. Laboratory processing and any expedited option affect the result date. Confirm the expected turnaround before booking; a same-day collection appointment does not mean same-day laboratory results.
05
Review the next step
We connect the results to the concern, observations and sampling limits. Further inspection can be more useful than repeating samples if a damp area or odor remains unexplained. Cleanup or repair decisions need supporting building evidence.
