Do you take cases for both plaintiffs and defendants?
Yes. We accept engagements from either side — homeowner, insurer, contractor, HOA or manager — provided a conflict check clears. Our opinions do not change with who signs the retainer.

FAQs
Litigation Support — common questions
Will you testify at deposition and trial?
Yes. John P. Lapotaire, CIEC has testified in Florida state and federal courts on mold, IAQ and water-intrusion matters since 2010.
Can you review another consultant's report without a site visit?
Yes — record and standards review is a common early engagement. We will tell you plainly if a site inspection is needed before we can offer opinions to a reasonable degree of professional certainty.
What standards do your opinions rely on?
ASTM D-7338, IICRC S520, IICRC S530 (John is Chair of the S530 Committee), ANSI/IICRC S500 for water damage, and ANSI/ASHRAE 62.1 / 62.2 for ventilation.
