Mold inspection in New Jersey
An inspection that finds the water is worth more than a test that names the species. Remove growth without fixing the moisture and it returns in the same place.

A visual assessment is somebody walking the house with a moisture meter and often a thermal camera, looking for where water is or has been. A sampled inspection adds air or surface samples sent to a laboratory, producing a written report.
Most of the confusion about cost comes from not knowing which one is being quoted. The EPA does not recommend routine sampling, because the recommended action — remove the growth, fix the moisture — does not change based on which species is identified. Where a report earns its cost is when you need documentation rather than information.
Why older New Jersey housing holds it
Full basements under nearly every house, foundations that predate the idea that a basement wall should be a water barrier, and lower levels finished in the 1970s and 1980s with framing set directly against masonry and no vapour barrier behind it. Add a century of layered mechanical systems running through the same joist bays, and there are a great many places for moisture to sit unseen.
