WQB Mold Removal partners with an independent accredited lab to give Topsfield clients real, documented answers instead of a visual guess.
This service exists separately from inspection and remediation because sometimes all a Topsfield client needs is a number — for an insurance claim, a real estate deal, or plain peace of mind. 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.

Environmental Relative Moldiness Index testing analyzes dust samples using DNA methods for a broader property-wide picture.
Testing before remediation establishes a baseline; testing after confirms the work actually brought levels back to normal.
We recommend clearance testing be done by a different technician than the one who performed the work, for objectivity.

An inspection is a visual and moisture-based assessment; testing involves lab-analyzed samples with documented spore counts.
Some Topsfield clients only want clearance testing after a visible problem was already treated — either approach is fine.
Recent cleaning can temporarily lower airborne spore counts, so we'll advise on timing before your Topsfield appointment.
