The IICRC Mold Remediation Protocol, Explained for Homeowners

S520 is the standard professional mold remediation follows. Here is what each requirement means for a New Jersey home in plain language.

Every credible mold remediation job in New Jersey follows the same industry standard. Knowing its four pillars lets you judge any contractor in about five minutes.

Pillar one: safety and containment

Occupants and workers are protected before anything is touched. That means sealed containment, negative air pressure, PPE, and shutting down HVAC in the affected zone.

If a contractor proposes opening a wall without any of that, the standard is not being followed and cross-contamination is nearly guaranteed.

Pillar two: document the conditions

Moisture readings, photographs, the extent of growth and the suspected cause are all recorded before work starts. This is both a quality control step and your insurance evidence.

Documentation continues daily, so the final package shows the structure actually reaching dry standard rather than being declared dry.

Pillars three and four: remove and verify

Contaminated porous materials are physically removed rather than treated in place — encapsulation alone does not satisfy the standard when material is colonized.

Verification closes the job: visual inspection plus sampling that confirms conditions have returned to normal for the building. Without it, you have a cleaned room and no proof.

Key takeaways

  • Containment, documentation, removal and verification are the four pillars
  • Encapsulating colonized porous material does not meet the standard
  • Ask for the verification result in writing before final payment
