Post-Remediation Verification: The Questions to Ask Before Paying

Clearance testing is the proof mold remediation worked. Six questions every New Jersey homeowner should ask before the final invoice.

The end of a mold job should look like a document, not a handshake. These are the six things to confirm before you release final payment.

The six questions

Who performed the verification, was it independent of the crew, what was sampled, how do indoor readings compare to an outdoor baseline, is the area visually clean and dry, and what were the final moisture readings on the repaired assemblies.

You should receive answers on paper. A verbal all-clear is worth nothing if the growth returns in September.

Why the outdoor baseline matters

Indoor spore counts are always compared to outdoor air on the same day, because normal indoor air is never sterile. A number without its baseline is unreadable.

Genus profile matters too: indoor air dominated by species that are scarce outdoors suggests an active indoor source, even at modest counts.

What happens if it fails

A failed clearance means additional cleaning and re-testing at the contractor's cost, not yours. Confirm that in writing before work begins.

Keep the verification report with your home records. It is exactly what a buyer's inspector will ask for at resale.

Key takeaways

  • Verification should be independent and in writing
  • Indoor counts only mean something against a same-day outdoor baseline
  • Re-cleaning after a failed clearance is the contractor's cost
