Air sampling, surface swabs, and ERMI dust analysis each serve a different purpose, and our Markham, VA technicians will recommend the method that actually fits your situation.
Every result comes with a written report you keep, regardless of what we find. We'll flag a sample as inconclusive rather than force a result that isn't reliable. Reordering a follow-up test later is quick since your baseline is already on record.
