Clearance testing in Coral Gables: what to know
Coral Gables's Spanish Mediterranean Revival mansions and estates from the 1920s–1940s use barrel tile roofs and stucco exteriors over hollow-tile or concrete block — moisture intrusion through failed stucco joints and tile underlayment is the primary mold driver in these historic properties.
The neighbourhood's mature tree canopy keeps surfaces shaded and moist, and fallen organic debris on roofs and in gutters creates micro-environments where mold colonises exterior surfaces and eventually penetrates the envelope.
High-value historic properties in Coral Gables require mold assessors with experience in historic construction to avoid damage to irreplaceable finishes during assessment and remediation.

- The written protocol specifies clearance testing as a completion requirement

- An insurance claim requires certified clearance documentation
- The remediator has offered to perform their own clearance (this should be declined)
- A previous clearance test failed and re-clearance is required after additional work
How we handle clearance testing in Coral Gables
Clearance testing is the final step of any IICRC S520-compliant mold remediation and the critical quality control measure that confirms the work was done correctly. The clearance test must be performed by an independent licensed mold assessor — the company or individual that performed the remediation cannot perform their own clearance test. This independence is mandated by the NYS 2015 Mold Law and is best practice in all markets.
The timing and conditions of clearance testing are specified in the written remediation protocol. Standard protocol requires that containment remains fully in place when samples are collected, that the HEPA-filtered negative air machine has been running for at least 4 hours before sampling, and that an outdoor control sample is collected simultaneously with indoor samples.
