Start with the repair history
Tell us when the damage appeared, which work has been attempted and whether the affected surface was recently covered or repaired. Photographs, dates and access to adjoining areas can be more useful than a description of color. We explain where observations support a decision and where further access is needed.
Separate known conditions from open questions
An accessible surface does not reveal every layer behind it. Moisture readings can support an investigation but need interpretation for the material and conditions. A proposal should identify the assumptions that could change if a cavity is opened or an adjacent source is investigated.
Turn findings into useful stages
The assessment should help decide which source work comes first, what material handling is proposed and when finishes can be considered. We discuss the needs of owners and other trades so that an inspection leads to a workable next step rather than an unexplained equipment reading.
Your questions
Does a moisture meter tell you which mold is present?
No. It measures a material-related electrical response or moisture estimate, depending on the instrument. It does not identify species.
Will you open the wall during an assessment?
Further opening may be needed in some projects. Access and any destructive investigation are discussed and agreed before work.
